OPINION

NICHOLSON, Acting P. J. —

Convicted of molesting his girlfriend's young sisters and sentenced to state prison for an indeterminate term of 75 years to life, defendant Edward Dale Mestas appeals. He contends (1) the trial court abused its discretion by refusing to hold an evidentiary hearing on some of the proffered evidence of the victims' sexual histories and (2) his trial counsel was constitutionally deficient for not investigating further the victims' sexual histories. We conclude (1) the trial court did not abuse its discretion by refusing to hold an evidentiary hearing on some of the proffered evidence of the victims' sexual histories because the alleged conduct was not sufficiently similar to the conduct charged in this case and, therefore, was not highly probative of the victims' credibility in this case and (2) the defendant's assertion that his counsel was constitutionally deficient fails because it is based on speculation concerning what further investigation may have revealed. Finding no error, we affirm.1

FACTS AND PROCEDURE

In early 2009, six-year-old T.M. and seven-year-old J.M. lived with their mother, their 20-year-old sister T.P., and defendant (who was T.P.'s boyfriend), as well as others, in Sacramento. While they lived together, defendant molested T.M. and J.M.

On different occasions, defendant masturbated in front of T.M., penetrated her anus with his penis, forced T.M. to orally copulate him more than once, pressed his penis against T.M.'s lips when she refused to open her mouth, and rubbed his penis on her back.

Defendant also masturbated in front of J.M. and forced her to orally copulate him.

The contentions raised on appeal — and our resolution of those contentions — do not require us to recount at length how the molestations came to light.2 However, we note that defendant denied molesting T.M. and J.M. He caught them watching pornographic videos. And he claimed that T.M. and J.M. accused him of the molestations after he had mistreated the family's dog.

A jury convicted defendant of committing two counts each of:

— a lewd act by force or fear on T.M. (Pen. Code, § 288, subd. (b)(1); counts one and five) and

— oral copulation of T.M. (Pen. Code, § 288.7, subd. (b); counts three and four). The jury also convicted defendant of committing one count of:

— oral copulation of J.M. (Pen. Code, § 288.7, subd. (b); count seven).

Finally, the jury found true the special allegation that defendant committed lewd acts on more than one child under 14. (Pen. Code, § 667.61, subd. (e)(4).)

The trial court sentenced defendant to five consecutive terms of 15 years to life for a total state prison sentence of 75 years to life.

DISCUSSION

I

Victims' Sexual Histories

Defendant contends the trial court abused its discretion and violated his constitutional fair trial rights by excluding evidence of the victims' sexual histories. He also contends that trial counsel was constitutionally deficient for failing to investigate the allegations of the victims' sexual histories. These contentions are without merit.

A. Evidence Code Section 782

(1) Generally, a defendant may not question a witness who claims to be the victim of sexual assault about the victim's prior sexual activity. (Evid. Code, § 1103, subd. (c)(1); People v. Woodward (2004) 116 Cal.App.4th 821, 831 [10 Cal.Rptr.3d 779].) Evidence Code section 782, however, provides an exception to this general rule.3 (See generally People v. Bautista (2008) 163 Cal.App.4th 762, 781-782 [77 Cal.Rptr.3d 824]; People v. Chandler (1997) 56 Cal.App.4th 703, 707-708 [65 Cal.Rptr.2d 687]; People v. Daggett (1990) 225 Cal.App.3d 751, 757 [275 Cal.Rptr. 287] (Daggett).)

Evidence Code section 782 requires a defendant seeking to introduce evidence of the witness's prior sexual conduct to file a written motion accompanied by an affidavit containing an offer of proof concerning the relevance of the proffered evidence to attack the credibility of the victim. (Evid. Code, § 782, subd. (a)(1), (2); Daggett, supra, 225 Cal.App.3d at p. 757.) The trial court is vested with broad discretion to weigh a defendant's proffered evidence, prior to its submission to the jury, "and to resolve the conflicting interests of the complaining witness and the defendant." (People v. Rioz (1984) 161 Cal.App.3d 905, 916 [207 Cal.Rptr. 903].) "[T]he trial court need not even hold a hearing unless it first determines that the defendant's sworn offer of proof is sufficient." (Ibid.; see Evid. Code, § 782, subd. (a)(2).)

If the offer of proof is sufficient, the court must conduct a hearing outside the presence of the jury and allow defense counsel to question the complaining witness regarding the offer of proof. (Evid. Code, § 782, subd. (a)(3); People v. Fontana (2010) 49 Cal.4th 351, 365-368 [111 Cal.Rptr.3d 1, 232 P.3d 1187].) "The defense may offer evidence of the victim's sexual conduct to attack the victim's credibility if the trial judge concludes following the hearing that the prejudicial and other effects enumerated in Evidence Code section 352 are substantially outweighed by the probative value of the impeaching evidence." (People v. Chandler, supra, 56 Cal.App.4th at p. 708; see Evid. Code, § 782, subd. (a)(4).)

(2) Evidence Code section 782 applies when the defense seeks to introduce relevant evidence of prior sexual conduct by a child. (Daggett, supra, 225 Cal.App.3d at p. 757.) In Daggett, the defendant was convicted of molesting a child under the age of 14. (Id. at p. 754.) On appeal, he successfully challenged the trial court's refusal to hold a hearing pursuant to Evidence Code section 782 on the admissibility of evidence that the child had been previously molested by two older children. (225 Cal.App.3d at p. 757.) The defendant's offer of proof consisted of evidence that the child had told a mental health worker and a doctor who had examined him that he had been molested by two older children when he was five years old. (Ibid.)

The Daggett court discussed the relevance of a molest victim's sexual history: "A child's testimony in a molestation case involving oral copulation and sodomy can be given an aura of veracity by his accurate description of the acts. This is because knowledge of such acts may be unexpected in a child who had not been subjected to them. [¶] In such a case it is relevant for the defendant to show that the complaining witness had been subjected to similar acts by others in order to cast doubt upon the conclusion that the child must have learned of these acts through the defendant. Thus, if the acts involved in the prior molestation are similar to the acts of which the defendant stands accused, evidence of the prior molestation is relevant to the credibility of the complaining witness and should be admitted." (Daggett, supra, 225 Cal.App.3d at p. 757.)

B. Background

The defendant filed a motion, pursuant to Evidence Code section 782, to admit evidence of the victims' sexual histories. The motion stated: "[T]here has been documented suspicion and complaints by at least one of the minor victims, to wit, [T.M.], of a prior molestation. In addition, Defendant expects to introduce evidence of both minors hav[ing] access to and viewing pornographic movies prior to the allegations involving Defendant."

Counsel for the defendant filed a declaration supporting the Evidence Code section 782 motion, detailing information she had received.

Concerning J.M., the declaration stated that (1) when she was three years old and in foster care the boys in the home removed her shirt and underwear, kissed her on the lips, and touched her "private area"; (2) apparently about the same time she was cut with a knife in her private area; and (3) when she was five years old a foster mother caught her masturbating with a toothbrush.

Concerning T.M., the declaration stated that (1) when she was three years old she reported being molested in foster care in Kansas, but the specifics were "sketchy and unconfirmed"; (2) when she was four years old a foster mother observed her "`humping her younger brother and wanting to get under the covers'"; and (3) when she was five years old her foster mother caught her masturbating and telling J.M. to "`smell this.'"

As to both victims, the declaration stated that the victims were caught twice in 2009, when they were six and seven years old, watching pornographic movies.

The trial court considered the declaration and made the following rulings with respect to whether a hearing would be held on each of the seven allegations of sexual history contained in defense counsel's declaration:

1. The removing of J.M.'s shirt and underwear was not relevant because it was not necessarily sexual conduct; the kissing incident was not relevant because no similar conduct was charged in this case; and the touching of the private area was sufficiently relevant to be addressed at an evidentiary hearing.

2. J.M.'s being cut in the private area was relevant and could be explored in the evidentiary hearing.

3. J.M.'s masturbation with a toothbrush was also relevant and could be explored in the evidentiary hearing.

4. The report of molestation of T.M. in Kansas, which the trial court understood involved some kind of "gentle rubbing," was too vague to permit proper Evidence Code section 782 analysis.

5. T.M.'s "humping" her brother and trying to get under the covers with him was not relevant, even though it was sexualized conduct, because it was not similar to the facts of this case.

6. T.M.'s masturbation and telling her sister to "smell this" were not relevant because there was no similar conduct alleged in this case.

7. As to the pornographic movies, the court found that there was insufficient specificity concerning the content of the movies to determine whether the depictions were sufficiently similar to the facts of this case.

In summary, the trial court decided that the evidentiary hearing would explore only three of the allegations of sexual history, all involving J.M.: (1) the touching of J.M.'s private area by boys in a foster home; (2) the cut in J.M.'s private area; and (3) J.M.'s masturbation with a toothbrush.

At the evidentiary hearing, J.M., who was eight years old at the time of trial, testified that she did not remember any of these alleged incidents from when she was very young, as young as three years old. Based on that testimony, the court stated that it could not admit the evidence but that it was willing to hold a further evidentiary hearing if the defense found evidence — from the foster mothers, for example — of what happened to J.M. when she was younger.

Two days later, the court clarified that it was excluding the proffered evidence of J.M.'s sexual history under Evidence Code section 782, subject to admission under some other theory such as proof of prior injury, because J.M. did not remember the incidents and, therefore, they could not provide her with knowledge of sexual matters. The court added that it would have excluded the evidence under Evidence Code section 352 in any event.

C. Analysis

Defendant contends that the trial court abused its discretion by determining that three of the incidents recounted in defense counsel's declaration were not sufficiently similar to the facts of this case to require an evidentiary hearing. He also contends that exclusion of this evidence violated his right to a fair trial. Those incidents were (1) the boys in the foster care home removing J.M.'s shirt and underwear when she was three years old; (2) the Kansas report that T.M. was molested when she was three years old; and (3) T.M.'s masturbating when she was five years old.

(3) We first conclude that exclusion of the evidence of a victim's sexual history does not deny the defendant a fair trial. There is no fair trial problem with exclusion of all such evidence under Evidence Code section 1103. "That limited exclusion no more deprives a defendant of a fair trial than do the rules of evidence barring hearsay, opinion evidence, and privileged communications." (People v. Blackburn (1976) 56 Cal.App.3d 685, 690 [128 Cal.Rptr. 864].) Therefore, because the trial court may properly exclude all such evidence without violating a defendant's fair trial rights, there is no merit in the argument that not admitting some of the evidence under Evidence Code section 782 deprives the defendant of a fair trial.

(4) We next conclude that the trial court did not abuse its discretion by refusing to hold an evidentiary hearing on the proffered evidence. The alleged conduct was not sufficiently similar to the conduct charged in this case and therefore was not sufficiently probative of the victims' credibility to require an evidentiary hearing.

The allegation that boys in the foster care home removed J.M.'s shirt and underwear when she was three years old was not probative of J.M.'s credibility in this case. There is no allegation that she learned something from that incident that would inform the jury that some of J.M.'s testimony in this case may be false.

(5) Likewise, the Kansas report that T.M. was molested when she was three years old is not probative of her credibility. As defense counsel said in her declaration, the details of the molestation were "sketchy and unconfirmed." The purpose of an Evidence Code section 782 hearing is to establish the truth and probative value of the offer of proof, not to allow a fishing expedition based on sketchy and unconfirmed allegations.

Defendant's only argument that the court should have allowed an evidentiary hearing on the allegation of T.M.'s masturbation is that the court allowed an evidentiary hearing concerning the similar allegation that J.M. also masturbated. There is no logic to this because the probative value of each incident must stand on its own. In other words, that J.M.'s masturbation may have been probative does not establish that T.M.'s masturbation, at a different time and age and under different circumstances, was probative.

In any event, the trial court did not abuse its discretion by refusing to hold an evidentiary hearing on the allegation that T.M. masturbated when she was five years old and told J.M. to "smell this." Even if the trial court found the allegation true after a hearing, the evidence would have been excluded under Evidence Code section 352 because it had very little probative value with respect to T.M.'s credibility. The allegations against defendant were not similar or related to T.M.'s alleged masturbation.

The trial court did not abuse its discretion by refusing to hold an evidentiary hearing on these three allegations.

D. Effective Assistance of Counsel

Defendant further contends that trial counsel's representation was constitutionally deficient because she failed to investigate the facts that related to the Evidence Code section 782 offer of proof. This contention fails because there is no basis for concluding any such deficient representation prejudiced defendant.

(6) To demonstrate ineffective assistance of counsel, a defendant must show two things: deficient representation and prejudice resulting from the deficient representation. The standard for prejudice is whether there is a reasonable probability the defendant would have obtained a better result absent the deficiency. (People v. Avena (1996) 13 Cal.4th 394, 418 [53 Cal.Rptr.2d 301, 916 P.2d 1000]; Strickland v. Washington (1984) 466 U.S. 668, 687-688, 693-694 [80 L.Ed.2d 674, 693-694, 697-698, 104 S.Ct. 2052].) If there is no showing of prejudice, we need not examine counsel's performance. (Strickland v. Washington, supra, at p. 697.)

Here, there is no showing of prejudice. Defendant asserts that, if trial counsel had been more diligent, "more information regarding the complaining witnesses['] past sexual knowledge and conduct would have come before the jury." This is mere speculation. It assumes that, if trial counsel had done more investigation, she would have discovered facts that the trial court would have found admissible. It further assumes that such unknown facts would have been of a nature to undermine the jury's confidence in the victims' testimony. We will not assume there are such facts or that the trial court would have exercised its discretion to admit such unknown facts. Therefore, defendant has failed to establish that he would have obtained a better result absent trial counsel's alleged deficiency.

Defendant's ineffective assistance of counsel argument is without merit.
