OPINION BY
FORD ELLIOTT, P.J.E.:
Michael Anson Harrell appeals from the judgment of sentence of February 14, 2011, following his conviction of two counts of first degree murder and related offenses. We affirm.
The trial court has summarized the history of this case as follows:
At approximately 1:00 a.m. on January 18th, 2008, Amy Baney called 911 to report a shooting at the residence of 226 North Fourth Street. She identified the shooter as “Mike” on the phone. Two Sunbury police officers were dispatched [424]*424to the scene. The witness would again identify the shooter as “Mike” and told the officers he was a black male. The witness told police that “Mike” had used a “long gun; a rifle.” She also informed the officers that he had fled the scene by running through the backyard.
Inside the home the officers discovered a haze in the air. The officers identified the haze as smoke and smelled gunpowder. Through the living room into the kitchen, the officers discovered the body of the first victim, David Moore. The black male was lying face down, motionless. The officers checked Mr. Moore for possible signs of life, however there were none. The officers then proceeded upstairs. At the far end of the upstairs hallway, the officers noticed a wedged door and a pool of blood creeping out from under the door. They entered the blocked room through a door in the closet of an adjacent room. They discovered a young female, Crystal Gordon, propped against the door. After checking her vitals, the officers determined there were no signs of life.
As they continued their sweep of the area, the officers discovered footprints in the light snow covering of the early morning. One of the officers is a trained K9 officer, and he had his dog, Rocky, with him in his cruiser. As other officers arrived on the scene, the K9 unit was taken to the footprints at the back of the house. As the dog picked up the scent, the tracking began. The dog tracked the footprints over a significant distance. The officers were reassured they were on the right track as they repeatedly took notice of footprints along the way which looked similar to those footprints at the crime scene. At the intersection of Race Street and Eighth Street, Rocky stopped tracking.
The Commonwealth concedes it does not know why the dog ceased tracking. Possible explanations included that the dog was tired, it expected a reward, the scent was faint or gone, or the track stopped.
The tracking officer called another Officer to the scene. This officer also had a K9 unit with him. Rocky was taken up Race Street. The new K9 unit proceeded down Eighth Street. For about half a block, the second K9 unit wandered from one side of the street to the other, presumably looking for a scent. Finally, the K9 put its head to the ground and began tracking, with the officers being drug [sic] along. The Officer testified that as the dog was tracking, he was looking for footprints, however the snow had long since melted in the center of the street. As the dog turned into an alley, footprints did appear in the snow. The escorting officer would testify that the footprints he observed in the alley way looked very similar to those at the crime scene.
The K9 unit continued to track until he got to Fairmount Avenue. There the dog traveled up the steps and onto the porch of the house at 19 Fairmount. The officers retreated with the dog, down. the block to the parking lot of Alexander Motors. Other officers from throughout the area were then called to the scene. At about 2:30 a.m., an individual emerged from the house.
An officer on scene recognized the individual and identified him as Michael Harrell to the other officers. At that point, the officers approached, they instructed Mr. Harrell (hereafter Appellant) to get on the floor of the porch, and he complied. He was then taken into custody. At that point, a female[1] emerges from the dwelling and was tern-[425]*425porarily taken into custody. She was asked if anyone else is in the house. She responded that there are children in the house. The officers conducted a protective sweep of the house to ensure that no other individuals who might be armed and dangerous are in the house. They removed the children from their bedroom and colleet[ed] them in the front room of the house, along with the female. Finding no one else, the officers remained on scene while application was made for search warrants for the house. While conducting the sweep, the officers noticed a large blue tub in the kitchen, and the stove with glowing elements. There appeared to be water in the tub along with a pair of black sweat pants.
Appellant, at this time, was in violation of his parole as both the Omnibus Hearing Testimony of Officer Hare and the evidence in the record shows. There was also testimony concerning his failure to appear at a scheduled hearing and a bench warrant being issued for his arrest as a result. The testimony included a conversation held between Appellant and Officer Hare concerning Appellant’s decision to leave the state after his failure to appear.
As Appellant was being taken to Sun-bury Police department, he made a statement to Officer Hare that all he had done was “break her f* * *ing jaw, and I’m in custody for that.” He was then placed in the holding cell at Sun-bury PD.
At the same time, the lead investigators in the case were dispatched to the crime scene where they interviewed the eye witness and thoroughly reviewed the crime scene.
Appellant was observed at various times throughout the morning lying down on the bench in the holding cell. There was testimony that Appellant was provided a piece of pizza later in the day with a cup of water, but the pizza remained untouched. Appellant denies this event took place and maintains that he was denied a trip to the restroom and was ignored when asked what would happen to him.
From 8:30 a.m. to 9:44 a.m., the lead investigators were interviewing the eye witness to the murders in an attempt to settle some issues which had come to light from the information received from the witness. The investigators then decided to show the eye witness a photo lineup. A lineup was constructed, and consisted of eight photographs of eight black men. See Commonwealth’s Exhibit # 148. The lineup was given to the witness at 9:44 a.m. Prior to receiving the lineup, the witness was instructed to pick out the person who shot David Moore and Crystal Gordon, if that person was present in the photo lineup. She was also instructed that if that person was not present in the lineup, that she should not pick someone out. The investigator looked at his watch after he handed her the lineup. His testimony is that it took Amy Baney exactly 12 seconds to identify the picture of the defendant in the lower left corner of the exhibit. That photograph was, in fact, a picture of the Appellant.
At approximately 10:35 a.m. the morning of January 18t, Appellant was taken into an interview room. The lead investigators identified themselves, showed Appellant their identification, and informed him they were investigating the murders of David Moore and Crystal Gordon. He was asked if he could read and write the English language, and Appellant acknowledged that he could.
The lead investigator, Corporal Bramhall, then placed the Miranda [426]*426Warning form in front of Appellant. See Commonwealth’s exhibit # 276. Corporal Bramhall told the Appellant he was free to read along, and then the Corporal read aloud the rights and warning form to the Appellant. The Corporal would testify that it appeared to him that Appellant was reading along. Prior to giving the rights and warning form to Appellant, the Corporal filled out the particulars on the form, including Appellant’s name, date of birth, the time and date, the location of the interview, and the Corporal’s name. After reading the rights and warning portion of the Miranda Warnings, the waiver statement was read aloud to Appellant by Corporal Bramhall. When Appellant was asked if he understood those rights and the waiver, he acknowledged that he did. When Appellant was asked if he’d be willing to talk to the police, Appellant acknowledged that he would. He was asked if he had any questions, he indicated he did not. He was asked to sign the form, and he did. Then the interview commenced.
Appellant denied his involvement with the murders. Corporal Bramhall asked him then to recount his activities from the previous day, and Appellant complied. What is noteworthy about Appellant’s recollection of his daily activities is that he includes specific times — down to the minute — that he conducted his normal activities. This was the narrative portion of the interview.
At approximately 12:30 p.m., Appellant was informed by Corporal Bramhall that they did not believe his account of his prior day’s activities, and that they knew that he had killed both David and Crystal, they just didn’t know why. See Omnibus Pretrial Transcript pg. 44. The officers had amassed a great deal of information from the eye witness to the murders and from the female living with Appellant at the residence on Fairmount Avenue. After being confronted with this information, Appellant admitted to the murders. He then gave the officers a statement. The Appellant indicated that he used a .30 caliber carbine, .30 caliber carbine rounds, and fifteen rounds were fired. Fifteen shell casings were recovered at the scene of the crime.
Following that, he was asked to give a written statement. He agreed and was given a written statement form. The officers then left the room and Appellant wrote for a short time. He then sat without writing for a time, then wrote again, and then sat again. He then ripped up the statement. The Corporal entered the room, recovered the ripped pieces of paper, and reconstructed them. See Commonwealth’s Exhibit # 274. The statement reads, “I, Michael Harrell state the following: I went to Amy’s house and was involved in an altercation with the deceased.”
The officers asked Appellant to give another written statement. He complied and wrote “I will take the needle. I want to take the needle. Nothing is worse than this much grief or pain. I would like to take the time and get it over with at the earliest time, like tomorrow or right now,” and initialed the document, M.H. The officer then wrote a question,
“Why do you want to take the needle?”
Appellant replied, “Maybe the next life will be better,” and initialed again.
The officer wrote, “Did you kill someone today?”
Appellant replied, “Yes,” and initialed. The officer wrote, “Who did you kill?”
Appellant responded, “David and Crystal,” and initialed.
[427]*427The officer wrote, “How did you kill them?”
Appellant refused to answer. He was asked to give a taped statement and he refused.
As officers executed three warrants on the residence at Fairmount Avenue, they recovered several items of interest. A sneaker was recovered which belonged to the Appellant. The tread mark was analyzed and matched the tread mark in the footprints in the snow indicating defendant had, in fact, been at Amy Bane/s house. DNA evidence was recovered from the bullet casings, though it was not a positive match it gave a percentage of exclusion with regard to the individuals in the population and the defendant. There was testimony that the DNA on the casings was consistent with the Appellant’s DNA to the exclusion of over 90 percent of the population.
The Appellant and eye witness both gave accounts that other individuals were present at the crime scene. However, through police investigation, the presence of any of the individuals that either Appellant, or the eye witness indicated, was definitively ruled out — as there was testimony that each of the individuals were observed the night of the murder in another location.
While Appellant was housed at Nor-thumberland County Prison, his girlfriend visited him. A prison guard, sitting eight feet away, testified that he heard Appellant admit the killings to his girlfriend. Another guard would testify that he heard the Appellant state that the Commonwealth would never find the murder weapon.
A forensic pathologist testified that David Moore had seven areas of gunshot wounds. He would also testify that Crystal Gordon had seven areas of gunshot wounds through her body. His opinion, to a reasonable degree of medical certainty, was that the bullet paths line up if Ms. Gordon was in a crouched position, with her hands over her head. This position is inconsistent with Appellant’s contention during his oral statement to police that the victim was armed with knives when he shot her.
The eye witness gave several differing accounts of the events that transpired in the early morning of January 18th, 2008. Her accounts included various individuals being present, who were, in fact, not present. However, through all of her accounts, she consistently identified Appellant as the shooter.
Prior to trial, a Frye hearing was conducted to determine whether expert testimony would be allowed on the subject of false confessions. The Court held a two-day hearing and took testimony from “experts” in the field of false confessions and from others who refute the validity of such scientific endeavors. The Court determined that evidence of false confessions was not sufficient to pass the Frye standard and precluded the admission of such evidence at trial.
In addition, three search warrants were obtained throughout the course of the proceedings. Two of the search warrants signed by a magistrate, included D.N.A. samples from the Appellant; and a request for ammo, a laptop computer, and clothing items from the house on Fairmount Avenue. The third warrant covers the shoes the Appellant was wearing the on [sic] January 18th in the morning.
At trial, the Commonwealth requested at the conclusion of its case-in-chief to have any notes of interviews with defense witnesses turned over for use on cross-examination. Defense objected. This Court ruled that “any and all state[428]*428ments of the defense witnesses taken by-defense may be requested by the Commonwealth at the beginning of cross examination. Specifically in accordance with Commonwealth v. Brinkley and Commonwealth v. Perez, the statements are those statements that were signed, adopted, or otherwise shown to be substantial and/or verbatim statements of witnesses. The Commonwealth will need to elicit from each witness whether the witness provided any such statement to the defense. At that time the defense will provide all applicable statements to the Commonwealth, and the Commonwealth will be allowed and allotted sufficient time to review each such statement.” See Trial Transcript Volume II pg. 964.
Following a ten-day trial, Appellant was found guilty on all counts and was later sentenced. This appeal follows.
Trial court opinion, 7/13/11 at 1-8.
On February 14, 2011, appellant received consecutive life sentences on the two counts of first degree murder. Appellant was also sentenced to six to 12 years’ imprisonment for firearms not to be carried without a license, to be served consecutively to his life sentences. Two counts of aggravated assault merged for sentencing purposes. A timely notice of appeal was filed on March 9, 2011. Appellant timely complied with the trial court’s order to file a concise statement of errors complained of on appeal pursuant to Pa.R.A.P., Rule 1925(b), 42 Pa.C.S.A., and the trial court has filed an opinion.
Appellant has raised the following issues for this court’s review:
I. Whether [appellant]’s due process rights were violated where the police failed to create a recording of his interrogation and alleged confession?
II. Whether the trial court erred in precluding the expert testimony at trial of Dr. Richard Ofshe on the influence of police interrogation and the phenomenon of false confessions?
III. Whether the trial court erred when it ordered unredacted disclosure of the defense investigator’s reports from interviews of witnesses regarding subject matter beyond the scope for which the witness was being offered or questioned?
IV. Whether the trial court erred when it denied the motion to suppress [appellant’s statements to the police where such statements were made involuntarily and without a knowing, willing and voluntary waiver of his Miranda rights?
V. Whether the trial court erred when it denied [appellant’s motion to suppress physical evidence stemming from the search of his residence where the search warrants were defective and where the initial warrantless entry was not supported by probable cause or exigent circumstances?
VI. Whether the trial court erred when it denied the motion to suppress identification evidence where [appellant’s right to counsel during the photographic lineup was violated?
Appellant’s brief at 12.
In his first issue on appeal, appellant argues that his due process rights were violated by the failure to record his interrogation and confession. Appellant argues that the failure to reeoi'd his interrogation deprived him of an opportunity to establish that his confession was involuntary and the product of police coercion. According to appellant, the police deliberately failed to record the interrogation so [429]*429that appellant would be unable to contest the voluntariness of his confession by examining the surrounding circumstances including the police tactics employed, the length of questioning, promises made, etc. (Appellant’s brief at 24-25.)
In Commonwealth v. Craft, 447 Pa.Super. 371, 669 A.2d 394 (1995), this court held that custodial interrogations do not need to be recorded to satisfy the due process requirements of the Pennsylvania Constitution. Id. at 397.2 The majority of states, with the exception of Alaska and Minnesota, have not adopted a rule requiring police to record interrogations. Id. at 396. Nor has the United States Supreme Court been asked to determine whether the United States Constitution requires the recording of custodial interrogations as a matter of federal due process. Id. This court determined that the Pennsylvania Constitution does not require contemporaneous recording of statements and that the adoption of a rule requiring contemporaneous recording of custodial interrogation should be left to the Pennsylvania Supreme Court or the General Assembly, not an intermediate appellate court. Id. at 398. Appellant’s first claim fails.
Next, appellant contends that the trial court should have allowed his proposed expert, Dr. Richard Ofshe, to testify regarding the phenomenon of false confessions. According to appellant, Dr. Ofshe is a leading scholar on the issue of false confessions and related topics. (Appellant’s brief at 30.) As stated above, appellant argued that his confession was coerced. Appellant wished to present Dr. Ofshe to educate the jury regarding false confessions, that false confessions exist, how to recognize them, and police interrogation techniques in general. (Id. at 31.) Following an extensive pre-trial hearing, the trial court denied appellant’s motion to admit Dr. Ofshe’s testimony on the basis that it failed to meet the standard for admissibility set forth in Frye v. United States, 293 F. 1013 (D.C.Cir.1923).
As we held [] in Track v. Fellin, 817 A.2d 1102 (Pa.Super.2003) [ (en banc), appeal denied, 577 Pa. 725, 847 A.2d 1288 (2004) ], the Frye test sets forth an exclusionary rule of evidence that applies only when a party wishes to introduce novel scientific evidence obtained from the conclusions of an expert scientific witness. Track, 817 A.2d at 1108— 1109. Under Frye, a party wishing to introduce such evidence must demonstrate to the trial court that the relevant scientific community has reached general acceptance of the principles and methodology employed by the expert witness before the trial court will allow the expert witness to testify regarding his conclusions. Id., 817 A.2d at 1108-1109, 1112.
However, the conclusions reached by the expert witness from generally accepted principles and methodologies need not also be generally accepted. Id., 817 A.2d at 1112. Thus, a court’s inquiry into whether a particular scientific process is “generally accepted” is an effort to ensure that the result of the scientific process, i.e., the proffered evidence, stems from “scientific research which has been conducted in a fashion that is generally recognized as being sound, and is not the fanciful creations [sic] of a [430]*430renegade researcher.” See id., 817 A.2d at 1111 (quoting Blum v. Merrell Dow Pharms., Inc., 564 Pa. 3, 9-10, 764 A.2d 1, 5 (2000) (Cappy, C.J., dissenting)).
Reading Radio, Inc. v. Fink, 833 A.2d 199, 208 (Pa.Super.2003), appeal denied, 577 Pa. 723, 847 A.2d 1287 (2004) (emphasis deleted).
[A]s to the standard of appellate review that applies to the Frye issue, we have stated that the admission of expert scientific testimony is an evidentiary matter for the trial court’s discretion and should not be disturbed on appeal unless the trial court abuses its discretion. See Commonwealth v. Zook, [532 Pa. 79, 98-99], 615 A.2d [1] at 11 [(1992), cert. denied, 507 U.S. 974, 113 S.Ct. 1420, 122 L.Ed.2d 789 (1993) ]. An abuse of discretion may not be found merely because an appellate court might have reached a different conclusion, but requires a result of manifest unreasonableness, or partiality, prejudice, bias, or ill-will, or such lack of support so as to be clearly erroneous. Paden v. Baker Concrete Constr., Inc., 540 Pa. 409, 658 A.2d 341, 343 (1995).
Grady v. Frito-Lay, Inc., 576 Pa. 546, 559, 839 A.2d 1038, 1046 (2003). “[W]e emphasize that the proponent of expert scientific evidence bears the burden of establishing all of the elements for its admission under Pa.R.E. 702, which includes showing that the Frye rule is satisfied.” Id. at 558, 839 A.2d at 1045. “[I]n applying the Frye rule, we have required and continue to require that the proponent of the evidence prove that the methodology an expert used is generally accepted by scientists in the relevant field as a method for arriving at the conclusion the expert will testify to at trial.” Id., citing Commonwealth v. Blasioli, 552 Pa. 149, 152-53, 713 A.2d 1117, 1119 (1998).
Recently, in Commonwealth v. Szakal, 50 A.3d 210 (Pa.Super.2012), we upheld the trial court’s denial of the defendant’s request to call Dr. Debra Davis, an expert in the field of false confessions:
[I]f the expert is only testifying generally about the fact that false confessions happen, that is well within the grasp of the average layperson and expert testimony would not be required under Rule 702. The components of a false confession, according to Dr. Davis, include factors such as the interrogation tactics employed, the training of the law enforcement personnel involved, and the stress tolerance of the suspect. This [c]ourt found that testimony concerning these factors can be elicited (and attacked) through the testimony of other witnesses and is capable of being understood by the average juror. The jury can then make its own determination as to the weight afforded to the defendant’s confession. Therefore, Dr. Davis’ testimony was not proper because expert testimony is inadmissible when the matter can be described to the jury and the conditions evaluated by them without the assistance of one claiming to possess special knowledge upon the subject.
Id. at 228, quoting trial court opinion, 6/9/10 at 30-32. “We find no error with the trial court’s analysis and ultimate decision to preclude Dr. Davis’ testimony as it would not assist the trier of fact.” Id.
Similarly, here, in addition to identifying various problems with Dr. Ofshe’s methodology, the trial court opined that the issue of false confessions was not beyond the ken of the average layperson:
First, the Court is not convinced that any specialized knowledge is required for jurors to understand the proposition that a person possessing any of a number of unique factors (mental disability, fatigue, hunger, tender age, propensity [431]*431toward acquiescence to authority figures etc.) may be more susceptible to police interrogative techniques. Further, the jurors would certainly be able to evaluate any evidence or arguments presented at trial by the defense to advance a theory that the conditions of [appellant]^ interrogation, the techniques used by police, or the personal characteristics of [appellant] had an impact on the veracity or voluntariness of [appellant’s confession without the assistance of the proffered expert testimony. If anything, the testimony could confuse the issue by suggesting causal relationships which are not borne out by the research actually conducted.
Trial court opinion, 10/6/10 at 5; Commonwealth’s brief, Appendix A. We agree and find that the trial court did not abuse its discretion by precluding Dr. Ofshe’s testimony.
In his third issue on appeal, appellant argues that the trial court erred in directing him to turn over verbatim or substantially verbatim statements of defense witnesses. The trial court ordered as follows:
Any and all statements of the defense witnesses taken by defense may be requested by the Commonwealth at the beginning of cross examination. Specifically, in accordance with “Commonwealth versus Brinkley” and “Commonwealth versus Perez”, the statements are those statements that were signed, adopted or otherwise shown to be substantial and/or verbatim statements of the witness. The Commonwealth will need to elicit from each witness whether the witness provided any such statement to the defense. At that time the defense will provide all applicable statements to the Commonwealth, and the Commonwealth will be allowed and allotted sufficient time to review each such statement.
Notes of testimony, 10/21-11/19/10, Vol. II at 964.
In Commonwealth v. Brinkley, 505 Pa. 442, 480 A.2d 980 (1984), the defendant was ordered to turn over to the Commonwealth certain defense memoranda containing statements of four defense witnesses. Id. at 447-448, 480 A.2d at 983. Counsel objected to disclosure on the basis of the “work product” privilege. Id. at 448, 480 A.2d at 983. The Supreme Court of Pennsylvania rejected this argument, stating that, “The ‘protective cloak’ of the qualified work product privilege ‘does not extend to information which an attorney secures from a witness while acting for his client in anticipation of litigation.’ ” Id. at 449, 480 A.2d at 984, quoting Hickman v. Taylor, 329 U.S. 495, 508, 67 S.Ct. 385, 91 L.Ed. 451 (1947). However, in what has subsequently been characterized as dicta, the Brinkley court went on to remark that, “It is well established that where the Commonwealth has in its possession pretrial statements of its witnesses which have been reduced to writing and relate to the witness’ testimony at trial, it must, if requested, furnish copies of these statements to the defense. So too, where the defense attorney possesses pretrial statements of witnesses, the needs of the criminal justice system require disclosure.” Id. (citation omitted). “To ensure that justice is done, it is imperative to the function of courts that compulsory process be available for production of evidence needed either by the prosecution or the defense.’’ Id. at 450, 480 A.2d at 984, quoting United States v. Nixon, 418 U.S. 683, 709, 94 S.Ct. 3090, 41 L.Ed.2d 1039 (1974) (emphasis in Brinkley).
In a concurring opinion, Chief Justice Nix noted that the sole argument raised before the trial court and on appeal was [432]*432that the material was attorney work product and, therefore, privileged against disclosure. Id. at 459, 480 A.2d at 989. Chief Justice Nix agreed that the material disclosed did not fall within any accepted definition of “attorney work product.” Id. However, he maintained that had defense counsel objected on the grounds that disclosure of the subject statements was not authorized by the Rules of Criminal Procedure, the admission of the statements would have been error. Id. at 460, 480 A.2d at 990. Chief Justice Nix rejected any implication that a reciprocal prosecu-torial discovery right exists: “What compels me to write separately is the majority’s unnecessary attempt to bolster its conclusion that the statements were not ‘work product’ with dicta which implies that the Commonwealth should be entitled to full reciprocal discovery in criminal prosecutions. I strongly disagree with such a suggestion.” Id. “It would be a mockery of due process if the state could, in addition to relying on its infinitely more effective position as an investigating body and its superior resources, compel the defendant to lighten the prosecution’s burden of proving its case through the discovery process.” Id. at 461, 480 A.2d at 990, citing Murphy v. Waterfront Comm., 378 U.S. 52, 55, 84 S.Ct. 1594, 12 L.Ed.2d 678 (1964).
In Commonwealth v. Perez, 698 A.2d 640 (Pa.Super.1997), the Commonwealth made a blanket discovery request for any and all written statements from defense witnesses who were expected to testify at trial. Id. at 642. The trial court concluded that Brinkley required disclosure of statements that were signed, adopted or otherwise shown to be substantially verbatim statements of the witnesses. Id. The trial court compelled the defense to disclose a signed, notarized statement of Jose Rodriguez, finding that it was the only statement that met the requirements set forth in Brinkley. Id. The Commonwealth then used this statement to impeach Rodriguez’s testimony on cross-examination. Id.
This court determined that the trial court erred in approving blanket discovery of the defense witnesses’ statements. We noted that the comments in Brinkley which are read to create such discovery rights are dicta and are not controlling, and that Brinkley has not been affirmatively cited for the privilege of reciprocal discovery in any subsequent case. Id. at 643-644. As Chief Justice Nix observed, the only issue to be decided in Brinkley was whether the work product doctrine barred disclosure of the witness statements. Id. at 643. In Perez, the defendant did not claim work product, rather he argued that the Rules of Criminal Procedure did not entitle the Commonwealth to such a request for reciprocal discovery. This court agreed, citing Pa.R.Crim.P., Rule 573(C), 42 Pa.C.S.A. (formerly Rule 305): “Nowhere in this explicit rule does it grant a right to written or taped statements of defense fact-witnesses. Thus, although our Supreme Court has suggested that defense witness statements are discoverable, they have not amended the Rules of Criminal Procedure to include such broad and sweeping reciprocal discovery rights and until our high court advises otherwise we choose to read Brinkley narrowly.” Id. at 644, citing Commonwealth v. Stehley, 350 Pa.Super. 311, 504 A.2d 854, 858 (1986) (“[wjhile the rules specifically require the Commonwealth to disclose such witness statements, the rules do not provide [the Commonwealth] with reciprocal discovery.”).
Ultimately, however, while this court in Perez found that the trial court’s tacit approval of mutual discovery rights was in error, we affirmed on the basis that Rodriguez admitted giving a statement to a [433]*433defense investigator on the witness stand. Id. at 645. “It is basic law that when a witness has given a statement to a party and testifies on behalf of that party, an adverse party may obtain disclosures or that statement for review and use on cross-examination.” Id. (citations omitted).
Instantly, the trial court did not grant the Commonwealth blanket discovery, nor did the trial court tacitly approve a reciprocal discovery right as in Perez. Rather, the trial court directed that on cross-examination, the Commonwealth would need to elicit from each witness whether or not he provided the defense with a statement. (Notes of testimony, 10/21-11/19/10, Vol. II at 964.) If so, then such statements would be turned over to the Commonwealth at that time. (Id.) The trial court’s order applied only to statements signed, adopted or otherwise shown to be substantially verbatim statements. (Id.) This is in accordance with established law and the trial court did not approve mutual discovery. Commonwealth v. Presbury, 445 Pa.Super. 362, 665 A.2d 825, 831-832 (1995), appeal denied, 544 Pa. 627, 675 A.2d 1246 (1996) (discussing when prior inconsistent statements are admissible as substantive evidence).
Furthermore, contrary to appellant’s assertions on appeal, the trial court permitted the defense to redact the statements to remove opinions of the defense investigator, references to trial strategy, etc. (Notes of testimony, 10/21-11/19/10, Vol. II at 965.) Since the trial court was sitting as fact-finder, it was impossible to conduct in camera review to determine which statements were discoverable. (See trial court opinion, 7/13/11 at 16.) Therefore, the trial court and the Commonwealth agreed that the statements could be redacted by the defense. (Id.)
Appellant complains that some of the statements related to matters outside the scope of direct examination. (Notes of testimony, 10/21-11/19/10, Vol. Ill at 1352; appellant’s brief at 33-34.) However, he fails to specifically identify any such statement. We determine that the trial court’s order was not improper..
In his fourth issue on appeal, appellant claims that his statements to police were made involuntarily. Appellant claims that the trial court erred in denying his motion to suppress his inculpatory statements to police, where he did not knowingly, intelligently, and voluntarily waive his constitutional right to remain silent.
In reviewing the denial of a motion to suppress, our responsibility is to determine whether the record supports the suppression court’s factual findings and the legitimacy of the inferences and legal conclusions drawn from those findings. If the suppression court held for the prosecution, we consider only the evidence of the prosecution’s witnesses and so much of the evidence for the defense as, fairly read in the context of the record as a whole, remains uncontradicted. When the factual findings of the suppression court are supported by the evidence, the appellate court may reverse if there is an error in the legal conclusions drawn from those factual findings.
Commonwealth v. Lopez, 415 Pa.Super. 252, 609 A.2d 177, 178-79 (1992) (citation omitted).
A confession obtained during a custodial interrogation is admissible where the accused’s right to remain silent and right to counsel have been explained and the accused has knowingly and voluntarily waived those rights. The test for determining the [434]*434voluntariness of a confession and whether an accused knowingly waived his or her rights looks to the totality of the circumstances surrounding the giving of the confession.
Commonwealth v. Jones, 546 Pa. 161, 170, 683 A.2d 1181, 1189 (1996) (citations omitted). ‘The Commonwealth bears the burden of establishing whether a defendant knowingly and voluntarily waived his Miranda ‘rights.’[3] Commonwealth v. Bronshtein, 547 Pa. 460, 464, 691 A.2d 907, 913 (1997) (citation omitted).
Commonwealth v. Davis, 861 A.2d 310, 317 (Pa.Super.2004), appeal denied, 582 Pa. 708, 872 A.2d 171 (2005).
When deciding a motion to suppress a confession, the touchstone inquiry is whether the confession was voluntary. Voluntariness is determined from the totality of the circumstances surrounding the confession. The question of vol-untariness is not whether the defendant would have confessed without interrogation, but whether the interrogation was so manipulative or coercive that it deprived the defendant of his ability to make a free and unconstrained decision to confess. The Commonwealth has the burden of proving by a preponderance of the evidence that the defendant confessed voluntarily.
Commonwealth v. Nester, 551 Pa. 157, 162-163, 709 A.2d 879, 882 (1998) (citations and footnote omitted).
When assessing voluntariness pursuant to the totality of the circumstances, a court should look at the following factors: the duration and means of the interrogation; the physical and psychological state of the accused; the conditions attendant to the detention; the attitude of the interrogator; and any and all other factors that could drain a person’s ability to withstand suggestion and coercion.
Id. at 164, 709 A.2d at 882 (citations omitted). “The determination of whether a confession is voluntary is a conclusion of law and, as such, is subject to plenary review.” Commonwealth v. Templin, 568 Pa. 306, 310, 795 A.2d 959, 961 (2002), citing Nester, supra.
We agree with the trial court that appellant knowingly and voluntarily waived his Miranda rights and gave a voluntary confession. While noting the length of appellant’s detention and the time of day, the trial court found that several factors militated in favor of appellant’s confession being voluntary:
Notably, the method by which he answered the officer’s questions, his responses were completely responsive and he provided his initials after each answer. He read along with the officer while the officer read the Miranda rights and waiver form. Both reading words and hearing them spoken drastically increase the likelihood that Appellant comprehended their meaning. He did not appear tired or intoxicated. He was offered food, though he chose not to consume it. He was given a bathroom break. There was no testimony concerning Corporal Bramhall’s demeanor as being unorthodox or inappropriate. While the presence of two officers, with their sidearms at their sides, would seem to weigh on coerciveness, the Appellant’s experience with law enforcement diminishes the effect of such visual stimuli.[4]
[435]*435The officers’ statements to the Appellant, first that they did not believe his story and second that they knew he had killed Dave and Crystal elicited responses from Appellant which were not coerced. Appellant was in a sound mind during the questioning and in fact had regaled the officers with a two-hour narrative of his activities for the day in question. There was little in the record to suggest that Appellant is unable to psychologically deal with such accusatory statements. Indeed, Appellant himself testified at trial and demonstrated to the Court an extensive vocabulary and spoke very clearly.
The length of the interview was not unduly burdensome on Appellant’s will, nor was the fact that he was in custody at the time. He demonstrated a calm demeanor when escorted to the interview room. He spoke for two hours of the roughly four hour interview. While he certainly was not free to leave, his needs were accommodated. The fact that the officers confronted Appellant with the “holes” in his story and accused him of the murders was not impermis-sively [sic] coercive. A certain amount of psychological persuasion is permitted. See Commonwealth v. Williams, 537 Pa. 1, 640 A.2d 1251 (1994). In addition, Appellant demonstrated control of his faculties when he refused to explain where he had come into possession of the gun he used in the killings and when he refused to do a taped confession.
Trial court opinion, 7/13/11 at 22-23.
Appellant argues that his confession was involuntary because of the delay between his arrest and his arraignment. (Appellant’s brief at 41^42.) According to appellant, he was not arraigned on these charges until five months later, in violation of Pa.R.Crim.P. 519.5 (Id. at 42.) However, the record indicates that appellant was actually arrested on a detainer, and was not formally charged in this case until June 2008. Furthermore, this argument was not raised in appellant’s Rule 1925(b) statement and is waived on appeal. Pa. R.A.P., Rule 1925(b)(4)(vii), 42 Pa.C.S.A.
Appellant also argues that the fact the police did not record his interrogation and confession is evidence that it was coerced. (Appellant’s brief at 43.) We have already addressed this issue and concluded that the officers were not required to record appellant’s interrogation and confession. We also observe that appellant declined to have his confession taped.
The totality of the circumstances indicate that appellant knowingly and voluntarily chose to waive his Miranda rights and make a statement. The trial court did not err in denying appellant’s motion to suppress his inculpatory statements to police.
Next, appellant argues that the initial search of his home was unconstitutional as it was a warrantless search and there were no exigent circumstances present. Appellant also argues that the search warrants were insufficient and were tainted by the illegality of the initial, warrant-less search. We disagree.
A protective sweep is “a quick and limited search of [the] premises, incident to an arrest and conducted to protect the safety of police officers or others.” Maryland v. Buie, 494 U.S. 325, 327, 110 S.Ct. 1093, 108 L.Ed.2d 276 (1990) []. There are two levels of protective [436]*436sweeps: (1) officers can, without probable cause or reasonable suspicion, look in closets and other spaces close to the place of arrest from which an attack could be launched and (2) officers can search for attackers further away from the place of arrest if they can sufficiently articulate specific facts that justify a reasonable fear for the safety of officers on the premises. See Commonwealth v. Taylor, 565 Pa. 140, 771 A.2d 1261, 1267 (2001).
In re J.E., 907 A.2d 1114, 1118 (Pa.Super.2006), affirmed, 594 Pa. 528, 937 A.2d 421 (2007) (emphasis deleted).
Here, officers arrested appellant on the front porch of his residence. (Trial court opinion, 7/13/11 at 29.) However, they did not recover the weapon used to kill the two victims. (Id.) A female, described as frantic, exited the residence and informed officers that there were children inside. (Id.) Officers did not know at that time if there was anyone else involved in the shooting, if the murder weapon was inside the house, or if the children were in danger. (Id.) Under these circumstances, the officers were justified in performing a protective sweep of the residence.
Appellant also argues that the search warrants were insufficient, specifically those issued on January 18, 2008 and July 18, 2008. (Appellant’s brief at 49.) Appellant argues that the affidavits of probable cause omitted critical details including when Melissa Ranck last saw appellant in possession of the firearm; the reliability of the K-9 units and their handlers; and information regarding the Commonwealth’s key witness, Baney, such as her criminal history, her multiple versions of events that night, and the fact that she failed a polygraph test. (Id. at 50.)
As we have often indicated, the legal principles applicable when reviewing the sufficiency of an affidavit to determine whether it establishes the probable cause necessary for the issuance of a warrant are well established. Before an issuing authority may issue a constitutionally valid search warrant, he or she must be furnished with information sufficient to persuade a reasonable person that probable cause exists to conduct a search. The information offered to demonstrate probable cause must be viewed in a common sense, nontechnical, ungrudging and positive manner. It must also be remembered that probable cause is based on a finding of the probability, not a prima facie showing of criminal activity, and that deference is to be accorded a magistrate’s finding of probable cause.
Commonwealth v. Baker, 532 Pa. 121, 126-127, 615 A.2d 23, 25 (1992) (citations omitted).
The affidavit of probable cause in support of the January 18, 2008 search warrant alleged, inter alia, that when officers arrived at the scene of the shooting they observed the two victims with multiple gunshot wounds. (Notes of testimony, 4/16/09, Commonwealth’s Exhibit 12.) Both were pronounced dead at the scene. (Id.) An eyewitness, Amy Baney-Banks, told police that a black male known as “Michael” shot the victims. (Id.) He was described as wearing black sweatpants, black sneakers, a black hoodie and carrying a brown and black firearm. (Id.) K-9 units eventually led police to 19 Fairmount Avenue, where appellant was taken into custody. (Id.) When officers entered the residence to secure the scene, they observed a tub filled with steaming water. (Id.) Inside the tub appeared to be a dark pair of sweatpants and bloody water. (Id.)
Melissa Ranck identified appellant as Michael Harrell and stated that he had a .30 caliber firearm, brown and black in color, which was consistent with Baney’s [437]*437description of the murder weapon. (Id.) Ranck also informed police that earlier that night, appellant was wearing a black shirt, black sweatpants and black Nike sneakers. (Id.) Baney identified appellant as the shooter in a photo array. (Id.) The January 18, 2008 search warrant application sought the clothing worn by appellant at the time he was taken into custody, including the black Nike sneakers. (Id.)
Clearly, the January 18, 2008 affidavit of probable cause was sufficient for a search warrant to issue. Police had an eyewitness, Baney, who identified appellant and stated that he was the shooter. K-9 units tracked appellant to the residence. Ranck confirmed that appellant was wearing black sweatpants and black sneakers that night and possessed a .30 caliber, brown and black firearm. When officers went inside the residence to perform their protective sweep, they observed bloody dark colored sweatpants soaking in hot water.
Appellant complains that the search warrant was tainted by the initial, illegal warrantless search. (Appellant’s brief at 49.) Specifically, appellant contends that the search warrant was based on the articles of clothing officers observed soaking in the kitchen. (Id.)
We have already concluded, for the reasons discussed above, that the warrantless entry was justified as a protective sweep. Therefore, officers were in a lawful position to view the bloody clothes. Furthermore, even if we disregard the allegation concerning the bloody sweatpants, there were sufficient independent facts to justify issuance of a warrant.
Regarding the July 18, 2008 search warrant application for the .30 caliber firearm, appellant claims it was based on “stale” information. Appellant argues that it was based on a photograph from 2006. (Id. at 50-51.)
The July 18, 2008 affidavit of probable cause alleged that, as stated above, Ranck identified appellant as Michael Harrell and stated that he owned a .30 caliber firearm matching Baney’s description of the one used in the shooting of January 18, 2008. (Notes of testimony, 4/16/09, Commonwealth’s Exhibit 13.) Ranck identified herself as appellant’s live-in girlfriend. (Id.) Officer Vern Petty also observed an October 2006 photograph of appellant holding a firearm. (Id.) The affidavit further alleges that on June 2, 2008, police were contacted by Randi Musser, the current tenant of 19 Fairmount Avenue. Musser related that she was contacted by Ranck’s half-brother who requested permission to go into the attic to retrieve the firearm. (Id.) According to Musser, Ranck wanted her half-brother to pull up the floor boards where the murder weapon was supposedly stashed. (Id.) An earlier search of the attic was conducted by police but portions of the attic could not be searched due to thick layers of insulation below the floor boards. (Id.) The search warrant affidavit requested permission to search the attic again using a sophisticated metal detector. (Id.)
Again, appellant’s argument is patently meritless. The July 18, 2008 affidavit was more than sufficient for a search warrant to issue regardless of the allegation concerning the October 2006 photograph. Police did not recover the murder weapon and they had new information that it may be stashed under the floor boards in the attic. The trial court did not err in denying appellant’s motion to suppress physical evidence.
In his sixth and final issue on appeal6, appellant argues that his constitu[438]*438tional right to counsel was violated when he was not provided counsel at the photographic line-up. As stated above in the recitation of the facts, Baney picked appellant out of a photo array the morning of January 18, 2008. Appellant asserts that he was entitled to have counsel present at that line-up.
Appellant is correct that in Pennsylvania, a defendant has a constitutional right to have counsel present during identification procedures. See Commonwealth v. Whiting, 439 Pa. 205, 266 A.2d 738 (1970), cert. denied, 400 U.S. 919, 91 S.Ct. 173, 27 L.Ed.2d 159 (1970), and its progeny.7 However, this right is triggered by the arrest of the accused. See Commonwealth v. DeHart, 512 Pa. 235, 253, 516 A.2d 656, 665 (1986), cert. denied, 483 U.S. 1010, 107 S.Ct. 3241, 97 L.Ed.2d 746 (1987) (“To extend the Sixth Amendment right to counsel during photographic identification proceedings to any person merely suspected of a crime would be an unreasonable burden on law enforcement officials and on the taxpayer, who in many instances must ultimately underwrite the cost of such representation.”).
Instantly, appellant was arrested on January 18, 2008 on a detainer for violating his parole, not for the murders. (Trial court opinion, 7/13/11 at 33.) Appellant was not formally charged with the offenses in this case until June 4, 2008, when the criminal complaint was filed. (Id.) Therefore, appellant did not have a right to counsel at the photographic line-up on January 18, 2008. See Commonwealth v. Blassingale, 398 Pa.Super. 379, 581 A.2d 183, 190 (1990), citing Commonwealth v. McKnight, 311 Pa.Super. 370, 457 A.2d 931, 934 (1983) (“in Pennsylvania, the right to counsel at a photographic array does not attach when the suspect is in custody for a different offense than that for which the array has been compiled.”).
At any rate, there was an independent basis supporting Baney^ identification of appellant at trial. See Whiting, supra, 439 Pa. at 210, 266 A.2d at 740 (“Since appellant’s right to counsel at the pretrial identifications was violated, the victim should not have been permitted to make her in-court identification, absent a showing that the identification had an ‘independent origin.’”) (citation omitted). Here, Baney testified that she had known appellant for approximately two years prior to the shooting and saw him “every day.” (Notes of testimony, 10/21-11/19/10, Vol. I at 366.) In fact, they had a sexual relationship “on and off’ until December 2007. (Id.) In
addition to the photo array, Baney clearly identified appellant as the shooter at trial. (Id. at 389.) Therefore, there was an independent basis for Baney’s identification. Appellant’s argument fails.
Judgment of sentence affirmed.
