We consider what evidence is required to establish that a sexual assault, victim is mentally retarded, to support that element of the offense of indecent assault and battery on a mentally retarded person, under G. L. c. 265, § 13F. We conclude that the evidence in the present case was sufficient to support the defendant’s conviction. We also reject the defendant’s contention that the trial judge abused his discretion in finding the victim competent to testify at trial.
The term “mentally retarded” is not defined in G. L. c. 265, § 13F. We accordingly look to the term’s “usual and accepted meaning!],” so long as it is “consistent with the statutory
“manifested by significantly subaverage intellectual functioning, existing concurrently with related limitations in two or more of the following applicable adaptive skills areas: communication, self-care, home living, social skills, community use, self-direction, health and safety, functional academics, leisure and work.”
A DMR service coordinator testified at trial that the victim was eligible to receive services from DMR, and that only persons with an IQ level below 76 were so eligible. The witness further testified that the victim’s IQ was significantly below that threshold, having tested at 33 in 1959 (at age 10) and at 27 in 1962, and that she required assistance with virtually all of her basic life skills, including managing her money, making and keeping medical appointments, and even keeping track of the days of the week. Given the severe impairment of the victim’s mental function, it is of no consequence that the evidence did not include testimony by an expert psychiatric witness.
The Commonwealth also presented sufficient evidence that the defendant was aware that the victim was retarded. The defendant assaulted the victim in her room on the first floor of a group home managed by DMR and the Massachusetts Association for the Blind. According to the DMR service coordinator, all of the residents of that group home were mentally retarded. The defendant had been employed at the group home for approximately five years at the time of the assault, and testified that his duties included caring for mentally retarded patients and that he had received training in the care of mentally retarded patients. Finally, the victim testified extensively at trial, and the
The victim’s retardation was, in fact, sufficiently pronounced that the defendant claims error in the determination by the trial judge that she was competent to testify at trial. However, the trial judge holds broad discretion to make that determination. See Commonwealth v. Whitehead,
Judgment affirmed.
Notes
The defendant made no objection at trial to the testimony of the DMR service coordinator.
The defendant’s contention that the evidence was insufficient to support a conclusion that he committed an indecent assault and battery rests on his claim that there was no evidence of the assault other than the victim’s testimony. The victim’s testimony, of course, provides sufficient direct evidence to support the jury’s conclusion. See Commonwealth v. Peters,
