OPINION
A jury convicted appellant Thomas Otis Palmer of aggravated sexual assault of a child and indecency with a child by exposure and assessed punishment, respectively, at life imprisonment and a $10,000 fine and ten years’ imprisonment and a $10,000 fine. In four issues, appellant complains (1) the jury charge contained error, (2) the evidence is legally and factually insufficient to establish penetration, and (3) the evidence is factually insufficient to estab *94 lish that the incident giving rise to both indictments occurred. Because we find error exists in the jury charge that caused appellant egregious harm, we reverse and remand.
Factual and PROCEDURAL Background
Appellant lived with his girlfriend, Jill, and her three minor daughters L.G., fourteen, complainant L.M., eight, and C.M., six. 1 On April 24, 2003, Jill moved with her daughters into the Brazoria County Women’s Shelter. Four days later, Ronald Weidman, a Child Protective Services investigator, interviewed L.M. Weidman asked L.M. if anyone had ever touched her inappropriately, and at that time, L.M. answered no. However, three days later, L.M. told Jill that one night while Jill was working, appellant exposed his penis to her and C.M. while they were on Jill’s bed and “stuck his finger inside of [L.M.].” He then asked if anyone had done that to her before and told her to smell his finger. L.M. later told an interviewer at the Children’s Assessment Center about the sexual assault. The State charged appellant with aggravated sexual assault and indecency with a child.
At trial, the State called Jill, who testified about L.M.’s outcry statement. L.M. then testified about the sexual assault. She said she did not remember if appellant touched her on the inside or outside of her vagina but that it hurt on the inside. She also said she initially did not tell anyone about the sexual assault because she was afraid of appellant. Some of L.M.’s testimony about the assault differed from Jill’s account of her outcry statement. 2 During cross-examination, appellant questioned her about these differences, and L.M. replied, “She probably didn’t hear me right.” Also during cross-examination, appellant asked L.M. about a similar sexual assault accusation she made about three years previously against her mother’s friend, Melissa Bridges. L.M. testified that she was lying on Jill’s bed when Bridges reached under her clothes and inserted her finger in L.M.’s vagina. As with appellant, an uninvolved third person was in the room when Bridges sexually assaulted L.M., and Bridges only assaulted her once.
The State also called pediatrician Dr. Sheela Lahoti, who testified that L.M. had a normal physical exam with “no evidence of penetrating trauma.” However, Dr. La-hoti also said that because the abuse allegedly occurred seven months prior to L.M.’s examination, it was “highly unlikely” that any injuries would still be visible. Mar-gaux LaFortune, a youth and family therapist who treated L.M., testified that L.M. exhibited some symptoms of post-traumatic stress disorder, suggesting she had experienced a traumatic event. Upon questioning by the State, LaFortune further testified that children who are coached to lie about sexual abuse are unlikely to be able to consistently “fake” emotional reactions to the alleged abuse.
Appellant called his step-mother, Jenny Palmer. Palmer testified that on April 24, 2003, she asked L.M. if appellant had ever touched her because Jill was “concerned about [appellant’s] actions.” L.M. told Palmer, “[N]o, he knows not to touch me because I would tell because I tell everything, don’t I, mommy?” Palmer said she asked L.M. the same question on three separate occasions, and L.M. always an *95 swered the same. At trial, L.M. testified that she did not remember Palmer asking her if appellant touched her inappropriately. She also said she did not remember meeting with Weidman or that he asked her if anyone had inappropriately touched her.
Analysis
In his first issue, appellant claims the jury charge contains error. In assessing such a claim, we first determine whether error exists in the jury charge.
Arline v. State,
The jury charge included the following instructions:
There is also testimony before you in this case concerning a previous allegation of sexual assault made by [L.M.] You cannot consider such evidence unless you first find beyond a reasonable doubt that the allegation made by [L.M.] was false, and even then, you may only consider the same in aiding you, if it does aid you, in judging the credibility of [L.M.] and for no other purpose,
(emphasis added).
A defendant seeking to impeach a witness with evidence of a previous false accusation against a third party must, as a threshold evidentiary matter, produce evidence showing the prior accusation is actually false.
See Lopez v. State,
Having found error, we next consider whether it constitutes egregious harm.
See Arline,
We find that, under these particular facts, the jury charge error caused appellant egregious harm. In its jury charge, the trial court subjected the evidence of L.M.’s prior accusation to an unnecessary and extremely high burden, thus effectively depriving appellant of impeachment evidence admitted during trial. The prosecutor compounded the jury charge error by repeatedly stressing the erroneous language throughout closing arguments.
See Ngo v. State,
In appellant’s second issue, he complains that the evidence is legally insufficient to support his conviction for aggravated sexual assault of a child. Specifically, he claims the evidence is insufficient to establish that he penetrated L.M.’s vagina with his finger. We address this claim even though we sustain appellant’s first issue.
See Rankin v. State,
We find the evidence legally sufficient to establish that appellant penetrated L.M. Under Texas case law, the slightest penetration of the female sexual organ is sufficient to uphold a conviction.
See Vernon v. State,
Because we find that appellant was egregiously harmed by an erroneous jury instruction, we reverse the trial court’s judgment and remand for a new trial.
Notes
. The girls’ ages refer to the time of trial, not the offense.
. L.M. testified that C.M. was not in the room when appellant touched her vagina but that appellant called her in afterward and then exposed himself to the girls. According to Jill, L.M. told her appellant called C.M. in the bedroom, exposed himself, and then touched her vagina.
. When the trial judge ruled that appellant could question L.M. about her prior accusation, he commented that “there is some evidence of falsity on that.” On appeal, neither side argues that the evidence was improperly admitted; thus, we do not consider whether the trial court abused its discretion in admitting it.
. We need not consider appellant’s third or fourth issues raising factual sufficiency challenges because, unlike his legal sufficiency challenge, neither issue would entitle appellant to an acquittal instead of remand; thus, their resolution is not "necessary to final disposition of the appeal.” Tex.R.App. P. 47.1.
