OPINION
ADELE HEDGES, Chief Justice.
Appellant, Jose Armando DeLeon, appeals from his conviction for indecency with a child by sexual contact. A jury found appellant guilty and assessed punishment at fourteen years in prison. In two issues on appeal, appellant contends that he received ineffective assistance of counsel in the guilt/innocence and punishment phases of the trial. We affirm appellant’s conviction; however, finding that appellant received ineffective assistance of counsel in the punishment phase, we remand for a new punishment proceeding.
I. Background
Complainant, a female less than seventeen years old, made an outcry statement to her mother in January 2007 that appellant, the uncle of her mother by marriage, had inappropriately touched her on several occasions. At trial, complainant testified that the first incident with appellant occurred in October 2004 when the family was living in Tyler, Texas, and she was in the fourth grade. Her brother had just been born, and her mother was in the hospital. Appellant, his wife, and youngest daughter travelled from their home in Bryan, Texas to see the baby. Complainant testified that appellant rubbed her “upper leg” with his hand while she was sitting on the couch watching television in the living room. The only other people in the apartment at the time were her younger sister and appellant’s daughter, both of whom were in different rooms. She recalled that she did not move or say anything because she was frightened. When he stopped, he got up from the couch, and nothing else happened on this occasion.
The next incident occurred during the fall of her fifth grade year, after her family had moved back to Bryan in 2005. She was at appellant’s house after school, sitting on a couch in the living room watching television. Appellant sat next to her and touched her above her clothing on her “bottom front area” or “private part” and then told her not to tell. Subsequently, appellant continued to touch her private part “every chance that he got,” on a couch in the living room, while her sister and his daughter were in his daughter’s room. Complainant further explained that anyone in appellant’s daughter’s bedroom could not see her and appellant on the couch. The incidents continued in appellant’s house on the couch through the fifth grade and into the sixth grade in 2006. Complainant stated that appellant became [379]*379“worse” during the summer of 2006, and he would unzip her shorts and “stick his hands in” her shorts, although not beneath her underwear. She also testified that he repeated a threat: “One day I’ll get you good.” The last touching occurred the week of her twelfth birthday in December 2006. Soon thereafter, in January 2007, complainant told her mother about appellant’s touching her.
Complainant said that she didn’t understand why appellant was touching her, and it made her angry. She further stated that during this time period she argued with her mother more than she had previously. On cross-examination, complainant acknowledged that she did not tell anyone except the prosecutor that appellant had touched her inside her clothing and made threats to her.
Complainant’s mother recounted the family’s move in 2002 from Bryan to Tyler and return to Bryan in 2005. After their return, both she and her husband were at work when school ended for her daughters, so they arranged for extended family to pick them up from school and either drop them off at the Boys and Girls Club or appellant’s house. She started to notice problems in complainant’s behavior in 2005, during the fall of her fifth grade year. Complainant became angry and disobedient at home and in public. Around December 2005, complainant’s behavior was so rebellious that she was suspended from the Boys and Girls Club. The mother further testified that when she was complainant’s age, she had acted similarly as a result of having been molested. Based on her own experience, she came to suspect that complainant may have also been molested. She therefore began to question complainant about possible molestation. Over the next year, complainant’s mother made this inquiry about “half a dozen” times. By December of 2006, complainant was having so much difficulty with her family that she was kept at home through the holidays instead of being babysat outside of the home.
Detective Loup of the Bryan Police Department, the primary investigator in Bryan for sex crimes and lead detective assigned to this investigation, testified regarding his five years experience working on sex crimes as well as his specialized training and education. He described this case as a delayed outcry, which he said was common for child victims. Further, he noted that there was no need to look for physical evidence since this was an indecent contact case, and nothing suggested otherwise. The first step in the investigation was to have the complainant interviewed by a forensic interviewer at Scotty’s House, a child advocacy center. After observing that interview, Loup interviewed several other people, including appellant via interpreter, one of appellant’s daughters, and complainant’s parents. In his interview, appellant denied the accusations against him. Loup stated that based on his investigation, the last offense occurred at appellant’s home and was committed by appellant.
Cheryl Mikeska, a licensed professional counselor, testified that she has fifteen years experience working with children. She has counseled over a hundred children who had been sexually abused. Her education includes a bachelor’s degree in psychology and a master’s degree in counselor education. She described the symptoms and behavioral characteristics of sexual abuse victims. She further described the symptoms and behavior complainant had exhibited. Although she acknowledged that complainant’s behavior could have been caused by something other than sexual abuse, she opined that there were clear indicators of her having been sexually abused.
[380]*380The defense called appellant’s youngest daughter as a witness. She is a second cousin to complainant and was seventeen years old at the time of trial. She recounted the trip to Tyler to visit complainant’s family when the baby was born. She only recalled being in complainant’s parent’s bedroom when the baby was in the apartment and did not notice any unusual behavior from complainant. Appellant’s daughter also testified to her long history of babysitting complainant and siblings. She disputed complainant’s description of her home and described her bedroom as being only “two steps” from the living room, close enough that she could see people sitting on the couch from her bedroom door. She testified that she was always around complainant when she was at her house and that complainant was never alone with appellant. She asserted that complainant had accused appellant because she wanted attention from her parents. She explained that complainant was treated worse than her other siblings because she had a different father. Finally, she claimed that complainant would lie to her parents and her on occasion about “any other little thing.”
At the punishment phase of the trial, defense counsel opened with a plea to the jury to recommend probation for appellant. In his opening statement, he also mentioned that appellant was a legal resident of the United States, coming originally from Mexico. The defense then called Charlie Russ, a Brazos County probation officer. He described the treatment for sex offenders on probation and the protections in place for the community against the potential danger posed by sex offenders on probation. Also, he testified as to the greater availability of treatment to those on probation versus those jailed or on parole. On cross-examination, the prosecutor elicited considerable testimony from Russ regarding his opinions on the psychology of sex offenders, including his conclusion that: “If you want to protect the public, then you put them in a situation where they can’t have access to children.”
The jury convicted appellant of indecency with a child by sexual contact and assessed punishment at fourteen years’ confinement.
II. Standards of Review
In his first issue, appellant contends that he was denied effective assistance of counsel during the guilt/innocence phase of trial. In his second issue, appellant contends that he was denied effective assistance during the punishment phase. The Sixth Amendment to the United States Constitution guarantees the right to reasonably effective assistance of counsel in criminal prosecutions. U.S. Const. amend. VI; McMann v. Richardson, 397 U.S. 759, 771 n. 14, 90 S.Ct. 1441, 25 L.Ed.2d 763 (1970). In reviewing an ineffective assistance claim, an appellate court “must indulge a strong presumption that counsel’s conduct [fell] within the wide range of reasonable professional assistance; that is, [appellant] must overcome the presumption that, under the circumstances, the challenged action might be considered sound trial strategy.” Strickland v. Washington, 466 U.S. 668, 689, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984). Under the two-pronged Strickland test, in order to demonstrate ineffective assistance of counsel, a defendant must first show that counsel’s performance was deficient, i.e., that his assistance fell below an objective standard of reasonableness; second, a defendant must affirmatively prove prejudice by showing a reasonable probability that, but for counsel’s unprofessional errors, the result of the proceeding would have been different. Thompson v. State, 9 S.W.3d 808, 812 (Tex.Crim.App.1999).
[381]*381Any allegation of ineffectiveness must be firmly founded in the record, and the record must affirmatively demonstrate the alleged ineffectiveness. Id. at 813. Appellant bears the burden of proving by a preponderance of the evidence that counsel was ineffective. Id. In the majority of cases, the record on direct appeal is simply undeveloped and cannot adequately reflect the alleged failings of trial counsel. Jackson v. State, 978 S.W.2d 954, 957 (Tex.Crim.App.1998). This is particularly true when the alleged deficiencies are matters of omission and not of commission revealed in the record. Id. A proper record is best developed in a habeas corpus proceeding or in a motion for new trial hearing. Jensen v. State, 66 S.W.Sd 528, 542 (Tex.App.-Houston [14th Dist.] 2002, pet. ref'd). To establish ineffective assistance of counsel based on a failure to object, appellant must demonstrate that the trial court would have committed harmful error in overruling the objection if trial counsel had objected. Alexander v. State, 282 S.W.3d 701, 705 (Tex.App.-Houston [14th Dist.] 2009, pet. ref'd).
III. Counsel’s Performance During Guilt/Innocence Phase
As stated, appellant asserts in his first issue that he received ineffective assistance during the guilt/innocence phase of trial. Specifically, he contends that counsel was deficient in that he failed to object to: (1) complainant’s mother’s testimony that she (the mother) had been molested as a child; (2) the mother’s testimony that complainant exhibited symptoms of having been molested; (3) the expert testimony of Cheryl Mikeska that complainant was sexually abused; and (4) the testimony of Detective Loup that appellant had indecent contact with complainant.
A. Mother’s Testimony Regarding Prior Abuse
Appellant first complains about complainant’s mother’s testimony that she was sexually abused as a child. Specifically, when the prosecutor asked the mother why she felt something was “going on” with complainant, the mother responded that complainant was acting the same way that the mother had when she [the mother] was molested as a child. In his brief, appellant contends that this testimony was irrelevant because it did not involve either complainant or appellant, or alternatively, that it was prejudicial because it “was offered to inflame the passion and sympathy of the jury to both the witness and her daughter.” He further asserts that trial counsel’s performance was deficient because he did not object to this testimony. However, even assuming that appellant is correct regarding the admissibility of this evidence, the record is silent as to why counsel did not object. There may have been strategic reasons for counsel to decline to object even to inadmissible evidence. See Thompson, 9 S.W.3d at 814 (declining to find that representation was either effective or ineffective given lack of explanation in the record for failure to object to hearsay); McKinny v. State, 76 S.W.3d 463, 473-74 (Tex.App.-Houston [1st Dist.] 2002, no pet.) (discussing various reasons why criminal defense counsel might strategically decide not to object to inadmissible evidence).1 Accordingly, we cannot say on this record that counsel’s [382]*382performance was deficient because he failed to object to the mother’s testimony that she had been molested as a child.
B. Mother’s Opinion Testimony
Appellant next contends that counsel should have objected to the mother’s testimony that complainant’s behavioral problems “made sense” after the mother learned of the molestation of complainant. Appellant specifically asserts that this testimony was inadmissible because the mother was not qualified as an expert on such matters. However, it does not appear from the record that this testimony was presented as expert testimony; instead it appears to have been only lay opinion evidence based on the mother’s own observations and prior experience. See generally Tex. Rule Evid. 701; Bargas v. State, 252 S.W.3d 876, 897-98 (Tex.App.-Houston [14th Dist.] 2008, no pet.). Appellant offers no argument as to whether this evidence would have been properly admitted as lay opinion evidence. Accordingly, he has not met his burden to show that counsel’s performance was deficient under the first prong of Strickland. See Alexander, 282 S.W.3d at 705.
C. Expert’s Testimony
Appellant next insists that counsel should have objected to Cheryl Mikes-ka’s expert opinion that complainant had been sexually assaulted. Generally, expert testimony is admissible if it assists the jury in intelligently determining an issue but does not decide the issue for the jury. See Duckett v. State, 797 S.W.2d 906, 914 (Tex.Crim.App.1990), disapproved on other grounds, Cohn v. State, 849 S.W.2d 817, 819 (Tex.Crim.App.1993); Drake v. State, 123 S.W.3d 596, 606 (Tex.App.-Houston [14th Dist.] 2003, pet. ref'd). Expert testimony that identifies certain physical or behavioral manifestations of sexual abuse and relates those characteristics to the complainant is admissible even if the complainant has not been impeached. Yount v. State, 872 S.W.2d 706, 708-09 (Tex.Crim.App.1993). However, “[e]xpert testimony does not assist the jury if it constitutes ⅛ direct opinion on the truthfulness’ of a child complainant’s allegations.” Schutz v. State, 957 S.W.2d 52, 59 (Tex.Crim.App.1997) (quoting Yount, 872 S.W.2d at 708).
In her testimony, Mikeska highlighted certain behavioral characteristics commonly exhibited by child abuse victims, including difficulty sleeping and eating, low self esteem, depression, poor interpersonal relationships, and isolation. She further spoke specifically regarding certain of those characteristics displayed by complainant. The following exchange then occurred between the prosecutor and Mikes-ka:
Q. And when you have these symptoms, what is your impression or diagnosis of [complainant]?
A. My impression with [complainant], particularly, is that there are clear indicators of her having been sexually abused.
Contrary to appellant’s suggestion, this testimony did not offer an ultimate conclusion regarding complainant’s truthfulness in this case. Mikeska merely stated that complainant exhibited the behavioral characteristics of a child who had been sexually abused. Expert testimony that a child exhibits behavioral characteristics that have been empirically shown to be common among children who have been abused has been held admissible in similar cases. See Perez v. State, 113 S.W.3d 819, 832 (Tex.App.-Austin 2003, pet. ref'd) (citing Hitt v. State, 53 S.W.3d 697, 707 (Tex.App.-Austin 2001, pet. ref'd), Vasquez v. State, 975 S.W.2d 415, 417 (Tex.App.-Austin 1998, pet. ref'd), Yount, 872 S.W.2d at [383]*383709, and Cohn, 849 S.W.2d at 819-21), overruled on other grounds, Taylor v. State, 268 S.W.3d 571, 578 (Tex.Crim.App.2008); see also Jiron v. State, No. 01-07-00441-CR, 2008 WL 1904068, at *3 (Tex.App.-Houston [1st Dist.] May 01, 2008, no pet.) (citing Perez). Accordingly, counsel was not ineffective for failing to object to Mikeska’s testimony. See, e.g., Ex parte White, 160 S.W.3d 46, 53 (Tex.Crim.App.2004) (holding counsel was not ineffective for failing to object to admissible evidence).
D. Detective’s Testimony
Next, appellant contends that his counsel was ineffective for failing to object to Detective Loup’s testimony, which “constituted an impermissible opinion as to the guilt or innocence of an individual.” The expression of guilt or innocence in any ease is a conclusion to be reached by the jury based upon the instructions given them in the court’s charge, coupled with the evidence admitted by the judge through the course of the trial. Taylor v. State, 774 S.W.2d 31, 34 (TexApp.-Houston [14th Dist.] 1989, pet. ref'd). No witness is competent to voice an opinion as to guilt or innocence. Boyde v. State, 513 S.W.2d 588, 590 (Tex.Crim.App.1974). After explaining how a typical sexual assault of a child investigation is conducted, including the interviewing of the child, Loup responded to the prosecutor’s additional questioning as follows:
Q. And in this case, based upon your investigation, did you determine where the indecency offense had occurred?
A. Yes. The last offense occurred at ... the suspect’s home. It’s in Bryan, Brazos County.
Q. Who, based upon your investigation, was the suspect or the person who committed this indecent contact with [complainant]?
A. Jose DeLeon.
The prosecutor’s questioning was improper. The prosecutor not only asked Detective Loup who he developed as a suspect during the course of the investigation, he also asked who committed the offenses and where the last offense occurred. See Huffman v. State, 691 S.W.2d 726, 730 (Tex.App.-Austin 1985, no pet.) (finding court erred in permitting prosecutor to ask deputy sheriff if he felt crime had been committed where appellant claimed he shot victim in self defense); see also Lovell v. State, No. 12-04-00291-CR, 2006 WL 1916950, at *3 (Tex.App.-Tyler Nov. 22, 2006, pet. ref'd) (mem. op., not designated for publication) (finding trial court erred in permitting prosecutor to ask police officer whether, based upon his investigation, officer believed defendant had “violated the law,” as this was merely an expression of opinion that officer believed defendant was guilty).
However, even assuming that counsel’s performance fell below an objective standard of reasonableness due to his failure to object to this testimony, in order to be entitled to a reversal for ineffective assistance of counsel under Strickland, appellant must further demonstrate that but for counsel’s error, the result of the proceeding would have been different. See Thompson, 9 S.W.3d at 812. We begin our analysis of the second Strickland prong by noting that Detective Loup did not directly state that he believed appellant was guilty; he merely indicated that his investigation pointed to appellant as the perpetrator. Loup was the first witness in the case, and apparently the prosecutor simply wanted to establish the circumstances under which appellant was arrested, ie., to “set the scene” for the witnesses to come. In addition, the prosecutor’s questioning was so garbled that it was unlikely to have left a clear im[384]*384pression regarding Loup’s personal opinions on the matter. Furthermore, the prosecutor did not continue the line of questioning or emphasize it in any way; he did not even mention it during closing argument. Instead, the prosecutor’s primary focus in both the case-in-chief and closing argument was on complainant’s credibility. For these reasons, we decline to find ineffective assistance of counsel under Strickland, based on this one isolated failure to object to potentially inadmissible testimony. See generally Ingham v. State, 679 S.W.2d 503, 509 (Tex.Crim.App.1984) (explaining that isolated failures to object to improper evidence generally do not constitute ineffective assistance of counsel); Moore v. State, 4 S.W.3d 269, 275 (Tex.App.-Houston [14th Dist.] 1999, no pet.) (same). Finding none of appellant’s assertions of ineffective assistance in the guilt-innocence phase to have merit, we overrule appellant’s first issue.
IV. Counsel’s Performance During Punishment Phase
In his second issue, appellant contends that he received ineffective assistance of counsel during the punishment phase of trial. Specifically, he alleges that counsel was ineffective for (1) injecting national origin by pointing out that he is a legal resident in the United States from Mexico; (2) calling a probation officer as an expert witness who then gave damaging testimony; and (3) failing to object to the prosecutor’s questions which elicited the damaging testimony. We will begin by reviewing the testimony of the probation officer.
During the punishment phase, appellant called Charlie Russ, a Brazos County probation officer, to the stand. On direct examination, Russ testified that when sex offenders are placed on probation, they receive treatment to learn to control their behavior, including “on how to push away any type of temptations or desires,” and “to remove themselves from high-risk situations.” He further stated that the hope was that the offender in question would “gain enough information to where they will apply it to the rest of their life and they will have the necessary abilities to remove themselves from situations that could trigger sexual behavior. It is just — it is education, and the importance of it is to prevent further sexual behavior.” Additionally, on re-direct examination, Russ explained that a sex offender on probation would definitely receive counseling and that within the prison system, as opposed to the probation system, offenders typically do not receive the same level of counseling.
On cross-examination by the prosecutor, however, Russ testified as follows:
Q. If in a particular case the facts were to show that what a person was convicted for was a situation where either through opportunity or through planning it was in a position where nobody else would see it, it was secretive; unless a child talked nobody would know. Is that risk still there if the people around aren’t trying to prevent that? A. Sure. That risk will always be there. The risk will never disappear. Regardless if they get alone with the child, regardless if there are other adults in the house, the risk remains. [¶] The risk is in the brain. It’s up here. It’s the desire. You can put a person in prison, you can do anything you want to them. You cannot get rid of the deviancy, the sexual desire, in any offender. [¶] Sexual behavior is natural, but when it becomes deviant, that is when we get worried. Once it is with them, it doesn’t disappear. That is the purpose of treatment. [¶] Punishment — I don’t care what kind of punishment you give some[385]*385body, it never forces the issues out of their brain. They will always have some kind of deviant sexual desire, and they will always be at risk to the community. That is just the way it works.
He subsequently expanded on this line of testimony on re-cross:
Q. Now rehabilitation of sex offenders: Are they ever rehabilitated to the point where the risk is gone?
A. No. Absolutely not. The risk will always be there. It may be minimized or lessened, but the risk will always remain because we don’t know — I don’t know what anybody here is thinking. We can never assume that we know what a sex offender is thinking. [¶] The risk is this: they were sex offenders before they committed the offense. So we don’t know what he is thinking, what they’re planning. We can give them treatment, we can do all the things that are required by law; but we can’t see up here, so we can never truly predict what is going to happen from day one to day two. [¶] You have got to assume all the risk because you have heard story after story, “I never thought he would do this; I never thought my grandfather would do this; I never thought my dad would do this.” [¶] So you never, ever push out the risk. You always assume the risk is great. As long as you assume the risk is great, then hopefully that is going to create enough protection to prevent other children from being impacted one way or the other. You just don’t know. [¶] I can have guys that do everything perfectly, but up here they’re still having sexual fantasies of molesting two-year-old girls or two-year-old boys. Just because you succeed well in probation does not remove the risk,
Russ went on to list various problems he’s encountered as a probation officer dealing with sex offenders. For example, he described one particular 75 year-old probationer who had a room in his home with “little girl dresses and some dolls and a little bed made up for them.” He further described how some offenders on probation have “toys and video games so they can invite the neighbors’ little kids to come over.” He concluded that: “If you want to protect the public, then you put them in a situation where they can’t have access to children.”
This testimony was particularly damaging to appellant’s prospects for probation or a short prison sentence. Appellant contends that he received ineffective assistance of counsel because counsel failed to object to this evidence and, in fact, presented Russ as a witness. Generally, when a defendant contends that his or her counsel was ineffective because he or she failed to object to evidence, the defendant must establish that such evidence was in fact inadmissible. See Ortiz v. State, 93 S.W.3d 79, 93 (Tex.Crim.App.2002). There has been no showing here, either at trial or on motion for new trial, as to whether Russ was qualified to give expert opinion testimony on these matters. However, whether or not Russ was qualified, appellant’s trial counsel was deficient in failing to object to the highly inflammatory testimony and for calling Russ to the stand in the first place. See Mares v. State, 52 S.W.3d 886, 892-93 (Tex.App.-San Antonio 2001, pet. ref'd) (holding counsel was deficient where counsel called probation officer as witness and then failed to object when she opined that a person in the defendant’s situation would not make a good candidate for probation); Jackson v. State, 857 S.W.2d 678, 683 (Tex.App.Houston [14th Dist.] 1993, pet. ref'd) (finding counsel was deficient for, among other things, calling Child Protective Services caseworker as witness who then “raised questions” concerning possible child [386]*386abuse); see also Ex parte Hill, 863 S.W.2d 488, 489 (Tex.Crim.App.1993) (holding counsel was deficient for calling alibi witness who had already pleaded guilty to same crime). Counsel should have known how Russ was going to testify on these matters. There could have been no strategic reason for producing and permitting such damning testimony. See Andrews v. State, 159 S.W.3d 98, 102 (Tex.Crim.App.2005) (“[W]hen no reasonable trial strategy could justify the trial counsel’s conduct, counsel’s performance falls below an objective standard of reasonableness as a matter of law, regardless of whether the record adequately reflects the trial counsel’s subjective reasons for acting as she did.”).2
Turning to the second Strickland prong, it is difficult to assess exactly what impact the testimony had on the jury. Without question, indecency with a child is a heinous offense, and juries have significant latitude in the punishment they may assess for such a crime. However, given the nature of this testimony and the emphasis placed upon it (Russ’s testimony took up 36 record pages of 71 total pages of testimony in the punishment phase, and he was the only witness who could be considered an expert presented during that phase), it is likely that it had an effect on the jury’s assessment of punishment. In other words, there is a reasonable probability, ie., one sufficient to undermine confidence in the outcome, that the result of the proceeding would have been different but for counsel’s deficient performance. See Andrews, 159 S.W.3d at 102. The jury declined to recommend probation, as appellant had requested, and instead assessed punishment of fourteen years imprisonment out of a range of between two years and twenty years. See Tex. Penal Code §§ 12.33(a) (providing punishment range for second degree felonies), 21.11(a)(1) (classifying indecency with a child by contact as a second degree felony).3 Accordingly, we find that trial counsel was ineffective, and appellant is therefore entitled to a new hearing on punishment. See Mares, 52 S.W.3d at 892-93 (remanding for new punishment phase where counsel called witness who gave damaging testimony regarding defendant’s candidacy for probation and failed to object to that testimony).
Because we find that counsel was ineffective for presenting Russ as a witness and failing to object to the prosecutor’s line of questions, we need not consider appellant’s other punishment phase argument, ie., that counsel was ineffective for [387]*387raising the issue of appellant’s national origin. We sustain appellant’s second issue.
We affirm appellant’s conviction; however, finding that appellant received ineffective assistance of counsel in the punishment phase, we remand for a new punishment proceeding
