OPINION
PER CURIAM.
¶ 1 Robert Wayne Lambert was tried before a jury in Creek County District Court, Case No. CRF-87-240, and convicted of two counts of First Degree Murder in violation of 21 O.S.1981, § 701.7. In accordance with the jury recommendation,1 the Honorable Donald [226]*226D. Thompson sentenced Lambert to death on each count. Lambert appeals his Judgment and Sentence.
Facts
¶2 On October 6, 1987, Robert Wayne Lambert and Scott Allen Hain robbed, kidnapped and murdered Laura Lee Sanders and Michael Houghton. At some point, Lambert and Hain locked the victims in the trunk of the car. Lambert cut the gas line and one of the defendants set the car on fire. The victims died of asphyxiation and thermal burns.
¶ 3 Lambert was originally convicted in 1988 of first degree murder of both victims and sentenced to death. He was also convicted of two counts of kidnapping, two counts of larceny of an automobile, two counts of robbery with a firearm, and one count of arson. Lambert appealed his Judgment and Sentence. In 1994, this Court reversed Lambert’s murder convictions and death sentences and remanded the case for a new trial.2 The Court affirmed the remaining convictions and sentences.
¶4 Before his re-trial, the State filed an Amended Information charging Lambert with First Degree Malice Murder and, in the alternative, First Degree Felony Murder.3 In 1996, the second trial was held. The jury again found Lambert guilty of two counts of first degree murder and sentenced him to death on each count.
Double Jeopardy Claims
¶ 5 In his first proposition of error, Lambert contends that double jeopardy barred his prosecution for felony murder. We disagree.
¶ 6 In 1988, Lambert was convicted of murder, kidnapping, larceny, robbery and arson. He appealed. In 1994, this Court reversed Lambert’s murder convictions because the State did not charge Lambert with felony murder in its original Information. The original Information only charged Lambert with malice murder. Relying on that Information, Lambert took the stand at his first trial, admitted the underlying felonies, but denied he intended to kill the victims. Then, over Lambert’s objections, the trial court instructed the jury on both malice murder and felony murder. The jury returned a general verdict of first degree murder, which this Court was compelled to treat as a finding of felony murder. The Court then concluded that Lambert was prejudiced and misled by the State’s failure to charge felony murder and found the murder convictions had to be reversed.4 The other convictions were affirmed, including Lambert’s conviction for robbery with a dangerous weapon. In affirming the robbery conviction, the Court stated, “We also recognize that should the State re-file the information charging felony murder, in addition to or in place of malice aforethought murder, the trial court can abrogate the conviction for armed robbery in the event Appellant is convicted of felony murder.”5
¶ 7 Before the second trial, the State corrected its error and filed an Amended Information charging Lambert with two counts of malice murder and, in the alternative, two counts of felony murder. The underlying felony for the felony murder charge was robbery with a dangerous weapon. The jury [227]*227was instructed on both felony murder and malice murder. Again, the jury returned a general verdict of first degree murder. The trial court did not abrogate the underlying felony conviction that was previously affirmed in Lambert I, and it does not appear that either party requested the court to do so.
¶ 8 On appeal, Lambert argues that his 1996 first degree murder convictions are barred by double jeopardy because he has already been convicted of the two underlying felonies — robbery with a dangerous weapon — and these felony convictions are final. Before getting into the merits of this argument, we note that we face the same problem that we faced in Lambert I and in Hain v. State.6 The jury, although instructed on malice murder and felony murder, returned a general verdict of first degree murder. This Court has “long held that a conviction for murder may be affirmed where alternative theories are charged when the evidence supports either malice aforethought or felony murder.”7 Here, the evidence supported either theory and the instructions on both theories were proper. However, because the jury returned a general verdict, we do not know under which theory the jury convicted Lambert.8 This Court has held that where the jury’s verdict does not specify either felony murder or malice murder, the verdict must be treated as one of felony murder.9 Thus, Lambert’s conviction must be treated as felony murder. We now turn to the merits of Lambert’s double jeopardy Claim.
¶ 9 It is well-established that when an appellate court reverses a conviction and remands the case for a new trial, double jeopardy does not bar re-trial. This principle known as “continuing jeopardy” is implicit in re-trials after a reversal on appeal and “ ‘has application where criminal proceedings against an accused have not run their full course.’ ”10 The Supreme Court has made clear that “[ijnterests supporting the continuing jeopardy principle involve fairness to society, lack of finality, and limited waiver.”11 Since this case concerns a re-trial after a successful appeal, it would appear that double jeopardy does not bar Lambert’s felony murder prosecution.
¶ 10 Lambert tries to get around this problem by arguing that jeopardy did not attach to the felony murder charge until 1996. According to Lambert, two separate prosecutions are at issue: the one in 1986, in which he was prosecuted for malice murder and the underlying felonies and at which jeopardy for malice murder and robbery attached; and the one in 1996, in which he was prosecuted for felony murder and malice murder and at which jeopardy for felony murder attached. Lambert argues that since jeopardy did not attach to felony murder until 1996, continuing jeopardy does not apply.
¶ 11 To the contrary, we find jeopardy for the charge of felony murder attached at the first trial. This Court has found that “where an information charges first degree malice aforethought murder, a conviction may be had for felony-murder if supported by the evidence.”12 Thus, if Lambert had not been prejudiced by the felony murder instructions, a conviction on those grounds would have been affirmed. Moreover, the failure to charge Lambert with felony murder was a due process error rath[228]*228er than a jurisdictional error. In Parker v. State,13 this Court stated:
Jurisdiction is conferred on the trial court by the commission of a public offense where venue properly lies in that trial court. 22 O.S.1991, §§ 121-136. Thus, a trial court’s jurisdiction is triggered by the filing of an Information alleging the commission of a public offense with appropriate venue. Therefore, this Court concludes that any failure to allege facts constituting the offense raises due process questions but does not affect the trial court’s jurisdiction.
Therefore, Lambert’s re-trial for felony murder is not a new and separate action.14
¶ 12 Lambert tries to persuade the Court that LaFevers v. State,15 controls and bars his prosecution for felony murder. Again, we disagree. In LaFevers, the defendant was originally tried and convicted of first degree burglary, first degree robbery, kidnapping, larceny of a motor vehicle; malice murder, third degree arson, first degree rape, and forcible anal sodomy. On appeal, the Court affirmed the burglary, robbery, kidnapping and larceny convictions, and reversed the malice murder, third degree arson, rape and sodomy convictions.16 LaFevers was re-tried and again convicted of malice murder. On appeal of the re-trial, LaFevers argued error occurred when the State charged him with felony murder in the re-trial since he had previously been convicted of the underlying felony of kidnapping and that conviction was affirmed, The Court agreed but upheld LaFevers’ conviction because LaFevers was convicted of malice murder and not felony murder. Lambert’s case is distinguishable from La-Fevers. First, in LaFevers felony murder was not charged or at issue in the first trial. Jeopardy for the felony murder charge thus did not attach until LaFevers’ second trial. Unlike Lambert’s case, the LaFevers ’ Court did not have continuing jurisdiction over the felony-murder charge, as we do here. Second, the Court in Lambert I clearly intended re-prosecution on felony-murder.
¶ 13 The real question here is whether affirming the robbery convictions in Lambert I somehow precludes prosecuting and punishing Lambert for felony murder. Under Oklahoma law, felony murder and the underlying felony merge into one offense.17 Traditionally, when this Court reviews convictions for both felony murder and the underlying felony, we sustain the murder conviction and vacate the underlying felony conviction.18 Lambert argues that the underlying felony convictions are final and the State cannot now exact a punishment for felony murder based on the same underlying felony. Lambert contends that to cure the “double punishment” problem [229]*229here we must set aside the felony-murder convictions rather than the underlying felony convictions.
¶ 14 The Court in Lambert I specifically retained jurisdiction over the underlying felony stating that “the trial court can abrogate the conviction for armed robbery in the event Appellant is convicted of felony murder.”19 Thus, we have jurisdiction over the underlying felonies as well as the murder convictions, and we can craft the appropriate remedy to cure any multiple punishment problem. The proper resolution of this problem is to vacate the convictions and sentences for the underlying felonies.
¶ 15 To dissuade us from this course of action, Lambert argues that the Court did not retain jurisdiction over the underlying felonies and that the language in Lambert I regarding the robbery convictions was merely advisory.20 Lambert I was not an advisory opinion. We clearly had appellate authority over the robbery convictions and clearly expressed that the district court could abrogate those convictions should Lambert be convicted of felony murder.
¶ 16 Lambert also seeks a constricted view of this Court’s mandate and scope of relief.21 In Greenwood v. State,22 the Court stated that when we issue an opinion or order, the trial court is empowered to enforce that opinion or order, but the trial court may not go beyond our mandate. The Court concluded that the trial court had the power to act on authority given to it by this Court in the body of the opinion, including specific, explicit instructions that may be set out in the opinion.23 Clearly in the body of Lambert I we granted the trial court authority to abrogate the underlying felonies. The trial court’s failure to do so was an error. We have authority to cure that error and to abrogate the underlying felonies at this time. By dismissing the underlying felony convictions, we cure the double jeopardy objections.
¶ 17 Moreover, 22 O.S.1991, § 1070 provides, “On a judgment of affirmance against the defendant, the original judgment must be carried into execution, as the appellate court may direct.” Here, the Court directed that the robbery convictions were to be affirmed but could be abrogated if Lambert was subsequently convicted of felony murder. Nothing in § 1070 defeats or limits the action taken by this Court in Lambert I. Likewise, 22 O.S.1991, § 1066 empowers this Court to do exactly what we did in Lambert I, and the underlying felony may be vacated.
¶ 18 The Court expressed and exercised its continuing jurisdiction over Lambert’s robbery convictions in its express language and instructions set out in Lambert I. The Court retains its continuing jurisdiction over the felony murder convictions. We now affirm the felony murder convictions and reverse with instructions to dismiss the underlying felonies of robbery with a dangerous weapon.
¶ 19 Lambert raises a second double jeopardy issue in his third proposition of error. Lambert contends that 21 O.S.1991, § 11 bars his prosecution for malice murder. As discussed above, the jury returned a general verdict of first degree murder, even though it was instructed on both malice murder and felony murder. In such cases, this Court treats the general verdict as felony murder. Since we must treat the verdict as one of felony murder, the question of wheth[230]*230er double jeopardy bars prosecution for first degree malice murder is moot.
Competency Issues
¶ 20 Prior to Lambert’s re-trial, the trial court conducted a post-examination competency hearing and found Lambert competent to stand trial. On appeal, Lambert raises several issues concerning his competency to stand trial.
¶ 21 In his fifth and thirteenth propositions of error, Lambert raises concerns regarding the admission of his confession at his competency hearing. In Proposition Y, Lambert contends that admission of his confession at his competency trial was error because the State failed to show that he knowingly and intelligently waived his rights before speaking with the police.
¶ 22 The post-examination competency hearing at issue here is the second time a jury has determined Lambert’s competency to stand trial. During Lambert’s initial appeal, this Court remanded the case for a retrospective competency proceeding.24 At the retrospective competency hearing, the State sought to introduce Lambert’s videotaped confession. The trial court held a Jackson v. Denno25 hearing and found that Lambert knowingly and voluntarily waived his rights. The trial court allowed the video tape to be shown to the jury. In Lambert I, we found that the trial court properly allowed this evidence at Lambert’s retrospective competency hearing.26
¶ 23 At the competency hearing before Lambert’s re-trial, the State again sought to have Lambert’s confession played to the jury. Both parties agreed to forego a Jackson v. Denno hearing and rely on the transcripts from the previous proceedings. Relying on those transcripts and this Court’s holding in Lambert I, the trial court allowed the confession to be played to the jury.
¶ 24 This Court decided this issue in LambeH I. In the current appeal, Lambert waived holding a new hearing and relied solely on the previous Jackson v. Denno hearing transcripts. As the Court found in Lambert I there is sufficient evidence to support the finding that Lambert waived his rights.27 We concur with our earlier opinion and find the trial court did not err in allowing this evidence at the competency hearing.
¶ 25 In his thirteenth proposition, Lambert argues that his competency hearing was unfair because the prejudicial impact of his confession outweighed its probative effect. As discussed above, the trial court did not abuse its discretion in allowing the confession to be heard. Lambert argues that playing the confession at the competency hearing was of little probative value. To the contrary, it gave the jury an example of Lambert’s ability to communicate, which was relevant to the issues before the jury. Moreover, this Court found this evidence relevant in Lambert’s 1991 retrospective competency hearing.28 The trial court did not abuse its discretion in allowing the video to be played for the jury.29 This proposition is denied.
¶ 26 In his eleventh proposition of error, Lambert contends the evidence is insufficient to sustain the jury’s finding that he was competent to stand trial. A defendant is deemed competent to stand trial unless he proves by a preponderance of the evidence that he is incompetent.30 Lambert contends that the jury’s finding that he was competent cannot be sustained under this [231]*231burden of proof. We disagree. The record amply supports a finding that Lambert was competent to stand trial under the preponderance of the evidence standard. This proposition is denied.
¶27 Lambert argues in Proposition XII that he was prejudiced in his competency trial by the introduction of other crimes evidence. Lambert failed to object to this evidence at trial and has waived review for all but plain error. The evidence elicited was relevant and probative to the issue of Lambert’s competence to stand trial. It related directly to Dr. Goodman’s evaluation of Lambert’s mental state. Admission of evidence of other crimes was not plain error and we decline to grant relief on this basis.
¶ 28 In Proposition XIV, Lambert contends it was error for four State witnesses to testify about Lambert’s competence. These four witnesses worked for the Department of Corrections and had regular contact with Lambert. The witnesses stated they found Lambert to be competent. They did not specifically state that he was competent to stand trial. Because these four witnesses were not experts, Lambert states that it was error to allow them to testify about Lambert’s competence.
¶ 29 Title 12 O.S.1991, § 2701 governs the admissibility of lay opinion testimony. Section 2701 provides:
If the witness is not testifying as an expert, his testimony in the form of opinions or inferences is limited to those opinions or inferences which are:
1. Rationally based on the perception of the witness; and
2. Helpful to a clear understanding of his testimony or the determination of a fact in issue.
In McGregor v. State,31 the Court stated, “Lay witnesses can testify about their observations of defendants if those observations are reasonably proximate in time to the proceedings.”32 Here, the State’s witnesses’ testimony was rationally based on their perceptions and aided the trier of fact. Under § 2701 and our case law, the trial court did not err in allowing this testimony.33
¶ 30 Lambert complains in his fifteenth proposition of error that the standard used to find him competent to stand trial is constitutionally infirm. As stated earlier, the court used the preponderance of the evidence standard as its burden of proof in this trial.34 Lambert asserts that error occurred because the trial court did not require the jurors to find that Lambert had a rational as well as factual understanding of the proceedings.
¶ 31 The trial court’s instructions comported with the Oklahoma Uniform Jury Instructions and 22 O.S.1991, § 1175.3. Lambert criticizes the Oklahoma competency definition and contends it runs afoul of Dusky v. United States.35 In Dusky, the Supreme Court stated that the standard for determining competency to stand trial is “whether [the defendant] has sufficient present ability to consult with his lawyer with a reasonable degree of rational understanding — and whether he has a rational as well as factual understanding of the proceedings against him.”36 This Court has considered Oklahoma’s standard for determining competency and found it consistent with the Dusky standard.37 We again find our competency standard is constitutional and comports with Dusky.
¶32 After reviewing all of Lambert’s alleged errors and defects in the competency proceeding, we find that the proceeding was [232]*232proper and comported with due process. We decline to grant any relief based on these claims of error.
Jury Selection Issues
¶ 33 In Proposition X, Lambert contends the trial court abused its discretion in refusing to allow individual voir dire. This Court has repeatedly stated individual voir dire is not required and the decision to allow individual voir dire is left to the sound discretion of the trial court.38 Lambert argues that in his case the trial court abused its discretion because of all the pretrial publicity in his case. Lambert overstates the pretrial publicity. Many of the jurors had not heard of the case and those who had heard of the case affirmed that they could put aside any preconceived notions they might have. Lambert has not shown that any jurors were not impartial, or that the trial court abused its discretion in denying him individual voir dire. We decline to grant relief on this basis.
Ineffective Assistance of Counsel
¶ 34 Lambert argues in his seventh proposition of error that trial counsel was ineffective for (1) failing to move for a change of venue, and (2) failing to listen to a taped confession in second stage. The standard for reviewing claims of ineffective assistance of counsel is well-established and was set out by the Supreme Court in Strickland v. Washington.39 In Strickland, the Court set out a two-part test for reviewing claims of ineffective assistance of counsel:
First, the defendant must show that counsel’s performance was deficient. This requires showing that counsel made errors so serious that counsel was not functioning as the “counsel” guaranteed the defendant by the Sixth Amendment. Second, the defendant must show that the deficient performance prejudiced the defense. This requires showing that counsel’s errors were so serious as to deprive the defendant of a fair trial, a trial whose result is reliable. Unless a defendant makes both showings, it cannot be said that the conviction or death sentence resulted from a breakdown in the adversary process that renders the result unreliable.40
Lambert’s counsel was not ineffective in failing to move for a change of venue. This issue had been raised and rejected in Lambert I and in Rain II.41 The decision to not seek a change of venue under these circumstances was a reasonable, strategic decision and it is likely that had the issue been raised, Lambert would have lost on the merits at both the trial and appellate levels. Moreover, many of the potential jurors had not heard of Lambert’s case. Those jurors who had heard of the case affirmed that they could put aside that information and fairly and objectively sit in judgment. Lambert has failed to show that counsel was ineffective in this regard.
¶ 35 Lambert argues trial counsel was ineffective because he failed to listen to a tape recording of Lambert’s statements to the police regarding other crimes prior to the admission of that tape during second stage. Trial counsel was very well-prepared, submitted many motions, and was a zealous advocate for his client. The information on the tape was not a surprise to counsel and was consistent with the evidence presented at trial. Indeed, trial counsel called Lambert to testify during second stage and Lambert’s testimony was consistent with the tape. Even if it may have been prudent for counsel to have listened to the tape, the tape was cumulative, not a surprise and consistent with Lambert’s second stage testimony. There was no prejudice and trial counsel was not ineffective.42
[233]*233
First Stage Issues
¶ 36 In his second proposition of error, Lambert argues the evidence is insufficient to support his felony-murder convictions. Under 21 O.S.1981, § 701.7(B), “[a] person ... commits the crime of murder in the first degree when he takes the life of a human being, regardless of malice, in the commission of ... robbery with a dangerous weapon.” Lambert claims that his use of an unloaded BB gun to rob Sanders and Hough-ton did not constitute robbery with a dangerous weapon, as that offense is understood under 21 O.S.1981, § 701.7. We reject this claim.
¶37 For the purposes of 21 O.S. 1981, § 701.7, the underlying felony of robbery with a dangerous weapon is defined in 21 O.S.1981, § 801.43 Section 801 provides:
Any person or persons who, with the use of any firearms or any other dangerous weapons, whether the firearm is loaded or not, or who uses a blank or imitation firearm capable of raising in the mind of the one threatened with such device a fear that it is a real firearm, attempts to rob or robs any person or persons, or who robs or attempts to rob any place of business, residence or banking institution or any other place inhabited or attended by any person or persons at any time, either day or night, shall be guilty of a felony, upon conviction therefor.
Under 21 O.S.1981, § 801, the crime of robbery with a dangerous weapon can be accomplished by means of an imitation weapon, which would include a BB gun. In McArthur v. State,44 this Court stated:
¶ 38 Significantly, section 801 allows for the consideration of a victim’s subjective belief when the weapon used is a firearm. The statute can be violated “whether the firearm is loaded or not” and forbids the use of “a blank or imitation firearm capable of raising in the mind of the one threatened with such a device a fear that it is a real firearm.”45
McArthur thus makes clear that § 801 can be violated when a defendant uses an imitation firearm' — like a BB gun — -to raise in the minds of the victims that the weapon is a real firearm. Lambert concedes that his use of a BB gun to rob Sanders and Houghton would violate § 801. He claims, however, that robbery with a dangerous weapon for the purposes of felony murder under 21 O.S.1981, § 701.7 is more narrowly drafted and that only actual use of a dangerous weapon triggers a first degree felony murder conviction.
¶ 39 In support of this argument, Lambert argues that § 801 is written in the disjunctive and that the use of the term “or” indicates that robbery using an imitation firearm is a separate and different offense from robbery using a dangerous weapon. He indicates that if the legislature had intended to include use of an imitation firearm under the umbrella of robbery with a dangerous weapon in § 701.7 they would have specifically done so.
¶ 40 Lambert analogizes to other cases involving limitations on the scope of felony murder. He first cites Richie v. State,46 in which this Court found that kidnapping by extortion was not an enumerated felony under § 701.7. However, in contrast to Lambert’s case, kidnapping by extortion is defined in 21 O.S.1991, § 745(A), whereas kidnapping is defined in 21 O.S.1991, § 741. Thus, Richie concerns two separate and distinct statutes; Lambert’s case concerns only § 801. Lambert also cites Boutwell v. [234]*234State.47 However, Boutwell concerns the construction of the murder for remuneration aggravating circumstance under 21 O.S.1991, § 701.12(3) and is not applicable to the facts presented in this case. These cases are not controlling and do not force the conclusion that Lambert would like.
¶ 41 Indeed, Lambert’s suggested narrowing of robbery with a dangerous weapon that is enumerated'in § 701.7 is inconsistent with this Court’s case law. In James v. State,48 the Court considered the scope of the underlying felony of robbery with a dangerous weapon under § 701.7. In James, the defendant had attempted to rob the victim, but was unsuccessful. During the course of the attempted robbery, the victim was shot and killed. The defendant argued that an attempted armed robbery was not among the enumerated felonies under § 701.7. The Court disagreed and “concluded that the Legislature intended to include attempted armed robbery in the felony murder statute, just as they intended to include attempted armed robbery in the statute defining armed robbery.”.49 Likewise, the Legislature intended to include robbery with an imitation weapon in the felony murder statute, just as they intended to include robbery with an imitation weapon in the robbery with a dangerous weapon statute.50
¶ 42 Moreover, in footnote 8 of Powell v. State,51 this Court set out the elements of first degree felony murder where the underlying felony is robbery with a dangerous weapon. The Court wrote:
The elements of First Degree Felony Murder with the underlying felony of Robbery with a Dangerous Weapon are: First, the death of a human; Second, the death ’occurred as a result of an act or event which happened in the commission of robbery with a dangerous weapon; Third, caused by the defendant(s) while in the commission of robbery with a dangerous weapon; Fourth, wrongful; Fifth, taking; Sixth, carrying away; Seventh, personal property; Eighth, of another; Ninth, from the person or immediate presence of another; Tenth, by force or fear; Eleventh, by use of a loaded/unloaded/ímiíaíiow firearm, or other dangerous weapon.52
Powell demonstrates this Court’s understanding that robbery with a dangerous weapon under § 701.7 includes robbery with an imitation firearm.
¶43 Finally, Lambert objects to the trial court’s instructions on felony murder.53 The trial court instructed the jury as follows:
No person may be convicted of murder in the first degree unless the State has proved beyond a reasonable doubt each element of the crime. These elements are: First, the death of a human;
Second, the death occurred as a result of an act or event which happened in the commission of a robbery with a dangerous weapon;
Third, caused by the defendant or any person engaged with he defendant while in the commission of a robbery with a dangerous weapon;
Fourth, the elements of the robbery with a dangerous weapon the defendant is alleged to have been in the commission of are as follows:
First, wrongful;
Second, taking;
Third, carrying away;
[235]*235Fourth, personal property;
Fifth, of another;
Sixth, from the person or the immediate presence of another;
Seventh, by force or fear;
Eighth, through use of a loaded or unloaded firearm or a blank or imitation firearm capable of raising in the mind of the person threatened with such device a fear that it is a real firearm or a dangerous weapon.54
Lambert objects particularly to the language in the eighth element in the robbery definition, as set out above. However, the language in the eighth element is identical to OUJI-CR 489 and OUJI-CR 2d ed. 4-144. The language is also consistent with, although not identical to, footnote 8 of Powell v. State, discussed above. The trial court’s instructions were proper.
¶44 Lambert insists that the trial court should have included an instruction defining firearms. The inclusion of the instruction was unnecessary under the facts of this case. We find the evidence sufficient to support Lambert’s conviction and find the trial court’s instructions were proper. This proposition is denied.
¶ 45 In his fifth proposition,55 Lambert contends that admission of his confession during the first phase of trial was error. During the first stage of trial, the State sought to admit the confession. The parties waived holding a new Jackson v. Denno hearing and asked simply that the court review the transcripts of the earlier proceedings. Relying on those transcripts and this Court’s decision in Lambert I, the trial court allowed the confession to be played to the jury. As discussed earlier in this opinion, in Lambert I the Court found sufficient evidence to support the finding that Lambert waived his rights.56 We concur with our earlier opinion and find the trial court did not err in allowing this evidence. Relief is denied based on this proposition of error.
¶ 46 In Proposition VI, Lambert complains that reversible error occurred in' the guilt phase of trial when the State’s rebuttal witness, Dr. Thomas Goodman, improperly referred to other crimes evidence and violated the prohibition against evidentiary harpoons. It is well-established that “when one is put on trial, one is to be convicted if at all by evidence which shows one guilty of the offense charged; and proof that one is guilty of other offenses not connected with that for which one is on trial must be excluded.”57 Other crimes evidence, however, is admissible if it “tends to establish motive, intent, absence of mistake or accident, identity or a common scheme or plan which embraces the commission of two or more crimes so related to each other that proof of one tends to establish the other.”58
¶47 In addition, the Court forbids witnesses from making “evidentiary harpoons” .that unfairly skewer the defendant. The Court has described evidentiary harpoons as voluntary statements generally made by experienced police officers or by lay witnesses59 that “are willfully jabbed rather than inadvertent” to inject other crimes evidence calculated to prejudice the defendant and which do in fact prejudice the defendant.60
¶ 48 Lambert argues that Goodman’s references to Lambert’s stealing, Lambert’s arson while in jail and an attempted sexual assault Lambert committed when he was a young adolescent constituted imper[236]*236missible evidence of other crimes or bad acts61 or alternatively was an evidentiary harpoon. The trial court had limited Dr. Goodman’s testimony regarding other crimes, and it is evident that Dr. Goodman referred to other crimes or bad acts in contravention to the court’s instructions. However, these references were brief and relatively innocuous. Under the circumstances, the error is harmless.62
¶ 49 Lambert also complains that the prosecutor improperly elicited from Thomas White that the BB gun used by Lambert in this case was stolen from White’s grandmother. At trial, Lambert objected to the evidence and the objection was overruled.63 This evidence was irrelevant other crimes evidence, and it should not have been elicited. However, again we must find that in light of the overwhelming evidence of guilt, the error was harmless.
¶ 50 In Proposition VIII, Lambert objects to: (1) photographs of the victims; (2) the State’s witnesses’ description of the victims’ bodies and the crime scene; and (3) Sanders’ mother’s testimony identifying the sleeping-bag found under Sanders’ burnt car. He argues the prejudicial effect of this evidence warrants reversal of his convictions. We disagree.
¶ 51 Without a doubt, the murders and the method of death in this case were horrible and of necessity the descriptions and photographs of this crime capture some of this horror. It is well established that “[t]he test for admissibility of a photograph is not whether it is gruesome or inflammatory, but whether its probative value is substantially outweighed by the danger of unfair prejudice.” 64 Moreover, “[t]he probative value of photographs of murder victims can be manifested in- numerous ways, including showing the nature, extent and location of wounds, establishing the corpus delicti, depicting the crime scene, and corroborating the medical examiner’s testimony.”65
¶52 At issue here are Exhibits G1 and G2, which were black and white photographs of the victims as they were found in the trunk of the car. Lambert cites Livingston v. State,66 in which the Court held that photographs of the charred remains of the victim laid out on the morgue table were prejudicial, although two small photographs of the victim at the crime scene and a photograph of the burned house were admissible. The photographs here are not as horrific as those discussed in Livingston and the photographs, as well as the witnesses’ testimony, were relevant in depicting the crime scene and corroborating the medical examiner.67 Lambert also objects to Exhibits J, R and S, none of which depicted the victims. The trial court did not abuse its discretion in admitting these photographs. Similarly, allowing the jurors to view the medical examiner’s report, which was relevant to the cause of death, was not an abuse of discretion. Finally, although several witnesses related what they found at the crime scene, the testimony was not unduly prejudicial, repetitive or un[237]*237justified. The prosecutor’s comments on this admissible evidence was not .error. Relief is not warranted.68
¶53 Lambert also complains about the State’s calling Laura Sanders’ mother to testify during first stage. Mrs. Sanders identified the sleeping bag that was found under Sanders’ burned car. Lambert objected to this evidence at trial and offered to stipulate that the sleeping bag belonged to Sanders’ brother.
¶ 54 In Hain I,69 during the first stage of trial, the State also called Mrs. Sanders to identify her daughter and some belongings. It is unclear from the Hain I opinion how extensive or emotional Mrs. Sanders’ testimony was. The Court concluded “the testimony of the relatives as to the identification of the victims and their belongings may have been unnecessary in light of other testimony to the same facts, at most it was merely cumulative. We do not find that fundamental error has occurred.”70 Here, Mrs. Sanders’ testimony was relatively straightforward and unemotional. She did not testify in an improper or inappropriate manner. Moreover, the State was not obligated to accept Lambert’s offer to stipulate to the ownership of the sleeping bag.71 The evidence.was relevant and no error occurred in allowing her to testify on this limited issue.
¶ 55 Lambert argues in his ninth proposition of error that the trial court should have given a second degree felony murder instruction. The trial court did instruct the jury on second degree depraved mind murder, but Lambert did not request, and the trial court did not give, a second degree felony murder instruction. The State argues the issue is waived. However, this Court has stated “the trial court should give such instructions whether requested or not if they are warranted by the evidence.”72 We review for plain error.
“Lesser included offenses should be given to the jury, but only when warranted by the evidence.”73 In Foster v. State,74 the Court stated that a second degree felony murder instruction should be given where there is evidence that the robbery was not accomplished through the use of a dangerous weapon.75 In Foster, however, the Court found the evidence did not warrant a second degree felony murder instruction where the defendant used a bat and a knife to beat and stab the victim. Under those facts, a lesser instruction on robbery by force or fear was not warranted.
¶ 56 Here, Lambert used a BB gun. The BB gun looked like a real weapon and was designed to place the victims in fear. Hain used a knife, which is clearly a dangerous weapon. Both the BB gun, as used here,76 and the knife, fall under 21 O.S.1981, § 801. Lambert’s actions fit squarely under § 801. A finding that the robbery was not accomplished by force or fear was not warranted by the evidence. The trial court did not err in failing to sua sponte give a second degree felony murder instruction.
¶57 Finally, Lambert argues that the failure to give the lesser instruction deprived the jury of its full sentencing options as required in Beck v. Alabama.77 Beck is [238]*238not applicable here because the jury was fully instructed on all its sentencing options, which included life imprisonment, life imprisonment without the possibility of parole and death.78
¶ 58 In conclusion, we find that none of the issues raised concerning the first stage of Lambert’s trial- are meritorious. We affirm Lambert’s murder convictions and vacate his robbery convictions.
Second Stage Issues
¶ 59 In Proposition IV, Lambert asks this Court to find the execution of the mentally retarded violates the state and federal constitutions. In light of Penry v. Lynaugh,79 we decline to grant relief.
¶ 60 In Proposition XVI, Lambert argues that during the second stage of trial the trial court should have held a Jackson v. Denno hearing regarding the admissibility of Lambert’s audio-tape confession of certain crimes committed in Kansas. This tape was introduced to prove the continuing-threat aggravating circumstance. Lambert did not object to the admission of the tape and he did not request a Jackson v. Denno hearing. The trial court asked Lambert about making a record and Lambert stated he had no objection to the introduction of the tape.80 A Jackson v. Denno hearing is not required in the absence of an objection to the evidence.81 Because Lambert did not object to the admission of the tape and did not request a Jackson v. Denno hearing, this issue is waived. The proposition is denied.
¶ 61 In Proposition XVII, Lambert challenges the constitutionality of the following aggravating circumstances: (1) continuing threat, (2) risk of death to more than one person, and (3) heinous, atrocious or cruel. He also contends the aggravating circumstances were not adequately defined. We disagree for the reasons set forth below.
¶ 62 This Court has repeatedly rejected attacks on the constitutionality of the continuing threat aggravating circumstance.82 Our case law compels us to deny this argument. Lambert also objects to OUJI-CR 2d 4-74, which defines the continuing threat aggravating circumstance.83 The instruction is consistent with our statutory and case law, and the trial court did not err in giving this instruction. This claim is denied.
¶ 63 Lambert argues that the risk of death to more than one person aggravating circumstance is overbroad. Under our case law, the killing of more than one person under the circumstances of this case satisfies this aggravating circumstance.84 This definition narrows the class of persons who may be executed and is not unconstitutional. This claim is rejected.
¶ 64 Lambert claims that the heinous, atrocious or cruel aggravating circumstance is also unconstitutionally broad. This Court has narrowed this aggravating circumstance by requiring a finding that death was preceded by “serious physical abuse.”85 However, Lambert contends the trial court did not adequately instruct the jury on this [239]*239narrowing construction of the aggravating circumstance. The trial court instructed the jury that:
As used in these instructions, the term “heinous” means extremely wicked or shockingly evil; “atrocious” means outrageously wicked and vile; “cruel” means pitiless, or designed to inflict a high degree of pain, utter indifference to, or enjoyment of, the sufferings of others.
The phrase “especially heinous, atrocious or cruel” is directed to those crimes where the death of the victim was preceded by torture of the victim or serious abuse.86
In contrast, OUJI-CR 2d 4-73 provides:
As used in these instructions, the term “heinous” means extremely wicked or shockingly evil; “atrocious” means outrageously wicked and vile; “cruel” means pitiless, or designed to inflict a high degree of pain, utter indifference to, or enjoyment of, the sufferings of others.
The phrase “especially heinous, atrocious,, or cruel” is directed to those crimes where the death of the victim was preceded by torture of the victim or serious physical abuse, (emphasis added)
Plainly absent from Lambert’s instruction is the word “physical” in the last phrase of the instructions. This error has occurred in other cases. In Mollett v. State,87 the Court found the omission of “physical” was not grounds for relief where there was evidence showing conscious mental suffering and physical abuse. In Johnson v. State,88 the Court found the absence of the word “physical” was error, but concluded the error was harmless and declined to grant relief. In Richie v. State,89 the Court concluded that since there was evidence of physical abuse, failing to include the word “physical” in the instructions was harmless, error.
¶ 66 Here, there was evidence of physical abuse prior to death. Houghton was stabbed in the back, and both victims had been kidnapped, restrained and forced into the trunk of the car. The mental anguish in this case was great as the victims were locked in the trunk of a car that was set on fire. Any error in failing to include the word “physical” was harmless.
¶ 67 In Proposition XVIII, Lambert contends that his Eighth and Fourteenth Amendment rights were violated by the introduction of unadjudicated offenses in second stage. This- Court allows the use of unadjudicated offenses to prove continuing threat.90 Accordingly, this proposition should be denied.
¶ 68 In his nineteenth proposition of error, Lambert complains that the trial court erred in refusing to give the jury an instruction on the meaning of life without the possibility of parole. This Court has held that it is not error for the trial court to fail to further define the sentence of life without the possibility of parole.91 Under our case law the trial court did not err in refusing to give Lambert’s requested instruction on life .without the possibility of parole.92
¶ 69 Lastly, Lambert argues in Proposition XX that cumulative error warrants relief. We disagree and decline to grant relief on this basis.
MANDATORY SENTENCE REVIEW
¶ 70. In accordance with 21 O.S.1991, § 701.13(C), we must determine (1) whether the sentence of death was imposed under the influence of passion, prejudice, or any other arbitrary factor, and (2) whether the evidence supports the jury’s finding of aggravating circumstances. The jury found the existence of three aggravating circumstances: (1) risk of death to more than one person; (2) heinous, atrocious or cruel; and (3) continuing threat. The evidence supported the ag-[240]*240gravatmg circumstances. Upon review of the record, we cannot say the sentence of death was imposed because the jury was influenced by passion, prejudice, or any other arbitrary factor contrary to 21 O.S.1991, § 701.13(C). Finding no error warranting modification, the judgments and sentences of Creek County District Court are AFFIRMED.
Decision
¶ 71. The Judgments and Sentences for First Degree Murder are AFFIRMED.
