Following a trial by jury in the Superior Court, the defendant was convicted of nine counts of rape of a child under sixteen (G. L. c. 265, § 23)
1. Dr. Serena Dеe, a pediatrician at the Greater Lawrence Family Health Center, was the final defense witness. At the time of her examination of the complainant, at least nine months after the last claimed act of intercourse, there werе no physical signs of any sexual abuse. On cross-examination Dee explained that, in most cases of confirmed sexual abuse, examination of the children’s external genitalia and vagina produced no physical findings. She gave her reasons for that phenomenon. In her opinion, injured tissue heals very rapidly in children and adolescents. She also testified that the complainant in the instant case had begun to menstruate at the age of nine and that this produced organic changes in vaginal tissue which made it impossible to tell whether a sexual battery had occurred. The defense rested its case on that somewhat equivocal note.
Thereafter, the prosecutor called Dr. Robert N. Reece, a pediatrician with expertise in the field of sexual abuse, as a rebuttal witness. That drew an objection from defense counsel, who complained that Reece’s testimony would be “somewhat redundant,” given Dee’s testimony on cross-examination “about the fact that [the physicians] don’t always find things.” Defense counsel also objected on the ground that he had insufficient notice of any studies or research materials upon which Reece might rely. The prosecution responded that she offered Reece’s testimony because the defense had raised the issue whether penetration had occurred and that she harbored some doubt about Dee’s qualifications “to provide a full picture to the jury ... of what is found or is not found” during pelvic exams. The judge overruled the defendant’s objection, noting that the defendant had opened up the subject and that the prosecution had given adequate notice to the defendant by listing Reece as a potential witness. The judge further remarked that defense counsel had declined, in spite of the judge’s earlier suggestion, to interview Reece before the trial commenced. She did, however, rule out the inclusion of references to learned trеatises or other articles in the field of sexual abuse of children in Reece’s testimony.
Because Reece’s testimony was different only in form, not in substance, from that of Dee, the concern about Reece’s
The defense’s claim of error as to the admission of Reece’s testimony rests on “the aura of reliability that the jury may find in expert testimony bearing directly on their own fact-finding role.” Commonwealth v. Francis,
It is settled that expert testimony on the typical symptoms or signs and general behavioral characteristics of sexually abused children is admissible and does not, of itself, constitute an opinion on the credibility of the complaining witness. See Commonwealth v. Richardson,
The case of Commonwealth v. Ianello, supra, does not help the defendant. The defendant in that case claimed that “the trial judge abused his discretion in refusing to allow a psychologist to give expert testimony as to the possibility of a [child’s] false allegation of sexual abuse arising from a custody and visitation dispute.” Id. at 199-200. The court determined that, “[w]hile the proрosed testimony fell short of rendering an opinion on the credibility of the specific child before the court, [there was] little difference in the final result,” and held that the trial judge properly excluded the proffered opinion because “an expert may not offer an opinion on a witnesses] credibility.” Id. at 201-202. Such “[e]valuations of credibility are, of course, within the exclusive province of the trier of fact.” Commonwealth v. Bohannon,
The case of Commonwealth v. Montanino, supra, is also distinguishable. In Montanino the child complainant had made statements to a police officer that were inconsistent with his trial testimony. At trial the police officer so testified. The Supreme Judicial Court reversed and held that it was impermissible for the police offiсer to testify, whether as an expert witness or as a lay witness, that it is normal for victims of sexual assault to reveal more details in subsequent interviews than they initially disclose. Commonwealth v. Montanino,
The reasoning in both of these cases does not support the defendant’s position here, because Reece’s testimony dealt with physiсal signs of sexual abuse and not with patterns of disclosure. Testimony pertaining to patterns of disclosure — that victims of child sexual abuse often fail to disclose their abuse until long after the fact, omit certain details, change their stories ovеr time, and give inconsistent statements, or that certain children are apt to lie about sexual abuse — goes directly to the truthfulness of the child complainant’s testimony and therefore usurps the jury’s function. Even if such testimony
Here, it appears that Reece’s testimony did no more than give the jury information concerning the medical interpretation of an absence of any physical evidence of penetration; namely, such a finding does not exclude that sexual abuse occurred. While thе jury were capable of assessing whether the complainant was telling the truth without the aid of either physician, the subject matter of Reece’s testimony was beyond the jury’s ken and was properly admitted.
We also reject the defendant’s argument that the prosecutor improperly exploitеd the admission of Reece’s testimony in his closing argument to the jury. The defendant takes umbrage at the prosecutor’s quoting Reece that “[i]t is normal to be normal.” The argument is unpersuasive because, when defense counsel arguéd, he also alluded to that part of Reece’s testimony that was in accord with Dee’s opinion that the absence of physical signs of trauma to the vaginal area is not necessarily indicative of child rape. The statement itself provided no detail that inculpated the defendant and, in light of the equivocal nature of the expert testimony, one could hardly conclude that it prejudiced the defense.
2. The defendant’s second point overlaps with the first. He argues that the judge mistakenly permitted the prosecutor to cross-examine Dee regarding conclusions that could be drawn from the lack of physical signs or symptoms of sexual abuse.
The objections were properly overruled. Although the risk of impermissible comparative testimony is usually heightened when the physician offering the general characteristics evidence also treated the child complainant, see Commonwealth v. Federico,
Judgments affirmed.
Notes
The trial judge subsequently granted the defendant’s motion for a required finding of not guilty on one of these counts of rape.
The defendant was acquitted on charges involving anothеr complainant, and an additional indictment was placed on file.
On the basis of the cases of Commonwealth v. Cancel,
The defendant also argues that Reece’s testimony on the percentages of children with confirmed sexual abuse histories who had actual physical findings was erroneously admitted, since “a mathematical probabilities formula does not lead to a valid conclusion about a specific individual.” Commonwealth v. Kappler,
See note 3, supra.
