COMMONWEALTH vs. JAMES W. MCDONOUGH.

LIACOS, J. In November, 1984, a Suffolk County grand jury indicted the defendant, James W. McDonough, for forcible, unnatural sexual intercourse with a child under the age of sixteen. [Note 1] The acts were alleged to have occurred between August 22, 1979, and May 14, 1982. After trial in the Superior Court in Suffolk County, the jury returned a verdict of guilty of statutory rape. G. L. c. 265, Section 23 (1986 ed.). [Note 2] The defendant was sentenced to a term of from seven to twelve years at the

Page 641

Massachusetts Correctional Institution at Cedar Junction. [Note 3] The defendant appealed, and we transferred the case to this court on our own motion.

We state some of the relevant evidence. [Note 4] The victim lived with his mother in South Boston until he was six or seven years old. When he was approximately four years old, his mother showed him something that he was "going to be doing." The victim demonstrated to the jury how his mother had put her fingers in his mouth in a sexually explicit manner. He testified that she stated that this conduct would make friends and would make people happy. When he was four to five years old, he met the defendant at his mother's apartment and performed fellatio on him in his mother's presence. The victim testified that he was scared when he did this; he thought that his mother would hit him if he refused. [Note 5] The victim could not remember how many times he had performed oral sex on the defendant, but he knew that it was more than once.

In January, 1982, when the victim was approximately six years old, he started to visit his father. In June, 1982, the father obtained temporary custody of the child. Permanent custody was granted to the father in April, 1983. In May, 1983, he told his father that he had performed fellatio on the defendant. [Note 6] The victim testified that he did not tell his father

Page 642

right away because he was nervous, afraid, and embarrassed. When his father asked why he had done this, he answered that his mother had taught him and "told [him] it was a good way to make friends."

The victim's father informed the State police. Lt. Thomas L. Mclaughlin of the State police spoke with the victim on August 10, 1983. The victim told the lieutenant that his mother initially had introduced him to pornographic material which depicted some of the acts she was talking about, required him to place his penis on her vagina, and told him that fellatio makes other people happy. He also told the lieutenant that he had performed fellatio upon the defendant and a male social worker for the Department of Social Services. [Note 7]

Lt. McLaughlin then called the defendant's home on January 5, 1984, to ask the defendant to come to the police station. The defendant went voluntarily to the station three hours later. He spoke with the lieutenant and with Corporal Jack Nasuti. Lt. McLaughlin read the defendant the Miranda warnings. The defendant then signed and dated a Miranda card. During an approximately forty-five minute conversation, the defendant admitted that the victim had performed fellatio upon him three or four times over a period of two or three months.

The defendant testified that he knew the victim and the mother. He denied allowing the victim to perform fellatio on him. When asked whether he remembered telling Lt. McLaughlin that the victim had "sucked [his] penis maybe four or five times," the defendant replied that he "might have said that, but out of fear or something."

On appeal, the defendant argues that the judge erred by (1) excluding the victim's hospital records; (2) refusing to allow two physicians to testify as expert witnesses; (3) excluding evidence of allegedly false accusations of rape; (4) allowing Lt. McLaughlin to testify as to the victim's fresh complaint; (5) "improperly" instructing the jury on fresh complaint evidence; and (6) denying the defendant's motion to suppress his statements at the police station.

Page 643

1. Hospital records. The defendant argues that the judge erred by excluding certain medical records of the victim. The judge based his ruling on the grounds that the records contained hearsay and privileged matter. The defendant claims that the Commonwealth failed to prove that the records came within the psychotherapist-patient privilege, G. L. c. 233, Section 20B (1986 ed.), primarily because a resident physician of Children's Hospital Medical Center, Dr. Barbara Burr, failed to qualify as a "psychotherapist" within the meaning of G. L. c. 233, Section 20B.

Conversations between a psychotherapist and a patient, relative to the diagnosis and treatment of the patient's mental and emotional condition set forth in writing in a hospital record otherwise admissible under G. L. c. 233, Section 79, may be inadmissible because of the statutory privilege. General Laws c. 233, Section 20B, defines "communications" to include not only the conversations but also any record, memoranda, or notes thereof. Usen v. Usen, 359 Mass. 453, 455-456 (1971). A trial judge may also exclude portions of an otherwise competent hospital record if he determines that the record's impact would be more prejudicial than probative. Commonwealth v. Perry, 385 Mass. 639, 642 (1982).

The judge stated that he had examined each page of the records that defense counsel wished to read to the jury. He found that most of the otherwise relevant material in the records was "totem pole," or multiple, hearsay, [Note 8] with the exception of

Page 644

portions relating to diagnosis and treatment which were inadmissible under the psychotherapist-patient privilege or the social worker-client privilege. G. L. c. 112, Section 135 (1986 ed.). He further found that the apparent purpose of introducing the records was to attack the victim's credibility, by showing that his father had psychiatric problems of his own. The judge noted that, although he had conducted extensive voir dire examinations to allow defense counsel to develop that theme, it had never been developed. After impounding and identifying privileged information, the judge copied and distributed the record to both counsel. The judge indicated that he had permitted counsel for the defendant to examine the hospital records in order to permit the defendant full confrontational rights when his counsel examined the victim's father.

General Laws c. 233, Section 20B, defines a "[p]sychotherapist" as "a person licensed to practice medicine who devotes a substantial portion of his time to the practice of psychiatry or a person who is licensed as a psychologist by the board of registration of psychologists; provided, however, that such person has a doctoral degree in the field of psychology or is a registered nurse" (emphasis supplied).

The defendant's claim that Dr. Burr does not qualify as a "psychotherapist" is based on his argument that a person licensed to practice medicine who devotes a substantial portion of his or her time to psychiatry is not qualified unless that person also possesses a doctoral degree in psychology or is licensed as a nurse. This interpretation files in the face of the clear language of the statute, the legislative history, and common sense. The statutory definition of a "psychotherapist" requires either a license to practice medicine and a substantial portion of time devoted to psychiatry or a license as a psychologist and a doctoral degree in psychology. General Laws c. 233, Section 20B, was amended in 1977 by inserting the language on which the defendant relies. St. 1977, c. 817. The proviso regarding the doctorate was part of the new provision bringing psychologists within the prior definition. It is unreasonable to assume that the Legislature intended the requirement of a doctoral degree in psychology to apply also to the original provision regarding physicians.

Page 645

In this case, Dr. Burr testified that she was a physician; that she had completed two years of a fellowship in child psychiatry, and that she was a resident in adult psychiatry at the time of trial. The judge ruled that Dr. Burr was a "physician specializing in psychiatry." We note that this court recently held in Robinson v. Commonwealth, 399 Mass. 131, 136 (1987), that the same doctor qualified as a psychotherapist within the meaning of G. L. c. 233, Section 20B. There was no error. [Note 9]

The defendant claims that the hospital records were relevant to the victim's bias, motive, and credibility. He also argues that the judge's "prohibition against use of the medical reports" to address the victim's mental stability and credibility deprived him of his constitutional right to cross-examination. This, the defendant maintains, resulted "in the denial of due process and of a fair trial, effective cross examination and confrontation as guaranteed by the Fifth and Sixth Amendments to the United States Constitution [and] Article 12 of the Massachusetts Declaration of Rights."

The defendant's characterization of the judge's ruling is misleading. The record establishes that the judge permitted counsel for the defendant to examine the hospital record and to use material from the hospital record to impeach the victim's father.

Page 646

The one passage from the hospital record which the defendant particularly complains of not being allowed to use stated: [Note 10] "In spite of some strengths, [the victim] is a child with a severe psychiatric disorder. This is manifest by cognitive confusion over the events of his life (e.g. inability to distinguish real episodes of sexual abuse from the abudant and constant suggestions he receives from his father). . . ." This passage appears in the victim's discharge summary from Children's Hospital, which was dictated by Dr. Burr and signed by Dr. Robert Riskind. It is repeated in a three-page letter to a social worker at Boston Children's Services, dated February 7, 1984, and signed by Dr. Burr, Dr. Riskind, Ester Schleifer, a licensed social worker, and Lee Farrington, a social work intern.

Assuming, without deciding, that this statement was an appropriate part of the hospital record, and further assuming, without deciding, that the statement was not inadmissible as an unusual or controversial diagnosis, Diaz v. Eli Lilly & Co., 14 Mass. App. Ct. 448, 454 (1982), any error in excluding the statement was not prejudicial; the statement was cumulative of evidence before the jury. Defense counsel cross-examined the victim extensively and vigorously in an effort to impeach his credibility and to bring forth inconsistencies in his testimony. [Note 11] The issue of the victim's credibility was more than adequately explored in the jury's presence.

As to the defendant's Federal constitutional claim, the Supreme Court has recently held in Pennsylvania v. Ritchie, 480 U.S. 39 (1987), that a criminal defendant charged with various sexual offenses was entitled only to have a trial judge review a confidential file in camera to determine whether it contained information that probably would have changed the outcome of

Page 647

his trial. The Court held that the Supreme Court of Pennsylvania had erred in holding that defense counsel must be allowed to examine the confidential information. The Court stated that "[t]o allow full disclosure to defense counsel in this type of case would sacrifice unnecessarily the Commonwealth's compelling interest in protecting its child abuse information." Id. at 1003. That case concerned a statutory privilege protecting records of a State protective service agency charged with investigating cases of suspected mistreatment and neglect of children. We note that the State's interest in protecting the confidentiality of patients' communications with psychotherapists is at least as strong as its interest in protecting disclosures to a State protective services agency. The judge below did more than is required under this Federal standard. We conclude that there was no violation of the defendant's Federal constitutional rights. [Note 12]

2. Expert testimony. The defendant argues that the judge erred in ruling that Dr. Burr and Dr. Riskind were not qualified to render an opinion whether the victim could distinguish real episodes of sexual abuse from imagined ones. After an extensive voir dire, the judge found that, while Dr. Riskind was qualified as an expert, he had no personal knowledge of the victim's mental and emotional condition.

Dr. Riskind, a board certified psychiatrist, had been chief of service and attending psychiatrist at the specialized pediatric unit at Children's Hospital, where the victim was treated. While all children admitted to the unit were assigned to him as the attending physician, Dr. Riskind testified that he never reviewed the victim's referral information and that he never interviewed the victim individually. Further, while he had to sign every official hospital document regarding children on his units, he had never discussed with Dr. Burr the statement which the defendant wished to introduce.

Dr. Burr testified that she had first seen the victim in January, 1984, a significant time after the alleged incidents. Her

Page 648

opinion at that time was that he was a child who "had difficulty forming relationships with adults, trusting adults, and talking about his feelings." Dr. Burr testified further that she had done no psychological testing of the victim, and that the victim "was unable to discuss any issues pertaining to alleged sexual abuse with [her]." She acknowledged, and the judge ruled, that "she is not in a position to assist this jury to determine whether or not the [victim], has or does not have the capacity to give objective evaluations and judgments about the real world, and, thus, appropriately advise the jury as to whether or not he was impaired to such an extent that fantasy overtook reality."

"[T]he qualification of a witness to offer an expert opinion on a given question is for determination by the trial judge as a preliminary issue of fact." Commonwealth v. Seit, 373 Mass. 83, 92 (1977). "Whether we say that he has a wide discretion in deciding the question, or that his ruling will be reversed only for error in point of law . . . the result is that such decisions at trial level are rarely upset on appellate review" (citations omitted). Id. See Commonwealth v. Perry, 385 Mass. 639, 645 (1982); Commonwealth v. Gaulden, 383 Mass. 543, 549 (1981). The judge's findings were amply supported by the evidence; there was no error. See Campbell v. Thornton, 368 Mass. 528, 540-541 (1975). Cf. Commonwealth v. Garabedian, 399 Mass. 304, 310 (1987).

3. Prior accusations of rape. At trial, defense counsel sought to introduce in evidence numerous allegedly false accusations of rape that were made by the victim. [Note 13] After a lengthy and extensive voir dire, the judge ruled that only one of the prior accusations was admissible for the limited purpose of impeaching the victim's credibility. On appeal, the defendant argues that the judge erred in excluding evidence regarding the victim's other allegations. [Note 14]

Page 649

At the voir dire, Lt. McLaughlin provided a list of persons upon whom the victim had allegedly performed fellatio. After disregarding references to other sexual activities, and to other children, the judge reduced the list to approximately eight names. [Note 15] The defendant sought to call several of the accused persons to testify as to the falsity of the accusations. The judge allowed counsel for the defendant to ask whether the victim had mentioned the defendant to Lt. McLaughlin, but prohibited inquiry as to the other names unless he could show that the accusations were false. In a memorandum of decision and order, the judge set forth in detail his reasoning and his conclusions on this issue.

Based on Lt. McLaughlin's list and the essentially duplicative list of the victim's father, the judge determined that defense counsel had made a showing that some accusations had been made by the victim. However, only one accusation, concerning the male social worker for the Department of Social Services, was shown to contain an independent basis for a claim of falsity because one Linda Saucier, who was allegedly present when the victim performed fellatio upon the social worker, provided an independent third-party basis of falsity. One individual testified and denied the allegations. The judge found that "his denial did not, in itself, constitute sufficient evidence of falsity or even an exaggeration of truth as required in [Commonwealth v. Bohannon, 376 Mass. 90 (1978), S.C., 385 Mass. 733 (1982), and Commonwealth v. Sherry, 386 Mass. 682 (1982)]." As to the other names, however, he ruled that there was "`"not a scintilla of evidence" showing that the statements

Page 650

were anything but true accounts of past events. Rather, the defendant[ ] engaged in speculation that the statements demonstrated the victim's "idiosyncratic and distorted perceptions." Conjecture about "distorted perceptions" cannot substitute for some evidence which would warrant the jury in finding the statements inaccurate.' Commonwealth v. Lefkowitz, 20 Mass. App. Ct. 513, 515-516 (1985)."

The judge also stated that "the defendant was not denied his right to develop a defense of bias at trial as he was allowed extensively to cross-examine the victim and his father and adequately to put before the jury the issue of the [victim's parents'] child custody battle. See Commonwealth v. Elder, 389 Mass. 743, 751 (1983) (`where evidence of bias is available by other means, no evidence of the complainant's prior sexual history should be admitted')."

The judge concluded that, although the defendant had adequate time and wide latitude to develop a claim of bias through a theory of false accusations, the evidence fell short of what is required. The judge ruled that "[i]n the case at bar, with respect to all but one of the supposedly prior false allegations of rape, it was not demonstrated that the `statements were false or even an exaggeration of the truth.' " Commonwealth v. Sherry, 386 Mass. 682, 692 (1982).

The defendant claims that he complied with the prerequisites for admission of prior false allegations of rape set forth in Commonwealth v. Bohannon, 376 Mass. 90, 95 (1978) (Bohannon I). He is mistaken. While his offers of proof -- a police report, a probation report, and certain medical records -- may constitute independent third-party records that allegations were made, they in no way provide a factual basis for concluding that the accusations were false.

"[T]he exception to the general rule barring evidence of prior false accusations is a narrow one. Bohannon I involved `special circumstances,' Commonwealth v. Sperrazza, 379 Mass. 166, 169 (1972) . . . and is applicable only in `unusual fact situations where justice demands.' Commonwealth v. Trenholm, 14 Mass. App. Ct. 1038, 1039 (1982)." Commonwealth v. Hicks, 23 Mass. App. Ct. 487, 489 (1987). In Commonwealth

Page 651

v. Sperrazza, supra at 169, we described the "special circumstances" of Bohannon I as follows: "[T]he witness was the victim in the case on trial, her consent was the central issue; she was the only Commonwealth witness on that issue, her testimony was inconsistent and confused, and there was a basis in independent third-party records for concluding that the prior accusations of the same type of crime had been made and were false." No such "special circumstances" warrant applying the exception of Bohannon I to this case. In Bohannon I, consent was the central issue. Here it was not an issue at all. Unlike Bohannon I, this victim was not the only witness on the central issue. The defendant himself admitted to Lt. McLaughlin that he allowed the victim to perform fellatio on him four or five times. At trial, after initially denying that he had made that statement, the defendant admitted that he "might have said it." Most important, there was no basis in "independent third-party records for concluding that the prior accusations of the same type of crime . . . were false." Sperrazza, supra at 169.

It was well within the judge's discretion to rule that defense counsel's offer of proof was insufficient to permit testimony of other witnesses and cross-examination of the victim regarding accusations of sexual misconduct against individuals other than the male social worker for the Department of Social Services. See Commonwealth v. Sherry, supra at 692-693; Commonwealth v. Hicks, 23 Mass. App. Ct. 487, 490 (1987). There was no error.

4. Fresh complaint. The indictment charges the defendant with rape of the victim "between August 22, 1979, and May 14, 1982, the exact date . . . unknown." The victim's father obtained temporary custody of the boy in June, 1982. The father testified that he did not recall if the victim stated to him, while he had temporary custody, that the defendant had sexually abused him.

Within one month after the father's obtaining permanent custody in April, 1983, the victim began telling him about sexual abuse by his mother and by the defendant. The father reported the incident to the State police, and the victim spoke with Lt. McLaughlin on August 10, 1983.

Page 652

Defense counsel called the victim's father as a witness and elicited from him his son's story concerning his sexual abuse by his mother and the defendant. He cannot, therefore, complain on appeal that the judge allowed in evidence the victim's complaint to his father.

As to the child's complaint to Lt. McLaughlin, the defendant objected to admission of the lieutenant's testimony because of the time that had elapsed between the alleged incidents of abuse and the child's complaint to the officer. When he admitted the conversation, the judge noted that "since the child has already testified that he was under some fear of the mother by virtue of physical abuse, [and] that as soon as he had an opportunity, he described what had occurred . . . according to our case law, such is considered a fresh complaint even though a considerable period of time has elapsed."

"The determination whether statements are sufficiently prompt to constitute fresh complaints rests within the sound discretion of the trial judge." Commonwealth v. Comtois, 399 Mass. 668, 673 (1987), citing Commonwealth v. Sherry, supra at 691. The test is whether the victim's actions were reasonable in the particular circumstances of the case. Id. Commonwealth v. King, 387 Mass. 464, 473 (1982). "There is no absolute rule of law as to the time within which the victim of a sexual assault must make [his or] her first complaint of the assault in order to qualify that complaint for admission in evidence as a fresh complaint." Commonwealth v. Bedard, 6 Mass. App. Ct. 959, 959 (1978). See Commonwealth v. Bailey, 370 Mass. 388, 391-393 (1976).

In the present case, the victim was a young child whose sexual encounters with the defendant were coached and monitored by his mother, with whom he lived. He testified several times that "she said if I didn't do it, she would hit me. So I kept on doing it." The victim told his father approximately one month after his father gained permanent custody. His father then told the State police the following month; and the child's interview with Lt. McLaughlin came two months later. Thus, the child's conversation with the lieutenant, which the judge admitted as fresh complaint, occurred three months after the father gained permanent custody of the boy.

Page 653

We have stated that, "where a young victim has been under the control of, and in reasonable fear of, a defendant who is a close relative, the promptness of a complaint is usually measured from the date when the victim leaves the defendant's control." Commonwealth v. Comtois, supra at 672 n.9, citing Commonwealth v. King, 387 Mass. 464, 473 (1982). In the particular circumstances of this case, where fear of his mother compelled the child's sexual activity with the defendant, we think the same rule should apply. There was no abuse of discretion in admitting the corroborative testimony of the lieutenant. [Note 16]

5. Instructions to the jury. The defendant next complains that the judge failed to give proper instructions regarding the fresh complaint testimony of Lt. McLaughlin. He argues that the judge did not instruct the jury that they must consider both whether the victim's complaints were made "reasonably promptly," Commonwealth v. Sherry, supra at 691, and whether they corroborated his testimony.

The defendant's argument relies on a selective reading of the transcript and ignores the judge's final instructions to the jury. When Lt. McLaughlin testified regarding the victim's fresh complaint, the judge gave a preliminary instruction, told the jury he would instruct them more fully at the conclusion of the case, and asked counsel whether he had stated the principle correctly. The defendant made no objection and offered no correction to the instruction which he now attacks. At the most, if there was error, we would review the challenged instructions only to determine whether the charge as given created a substantial risk of a miscarriage of justice. Commonwealth v. Drew, 397 Mass. 65, 81 (1986). There was, however, no error.

In his final instructions, the judge stated: "In considering such statements, you must first determine whether they were,

Page 654

in fact, a prompt complaint about the incident. If they were not a prompt complaint . . . you may not consider such statements at all." He added that they should only consider the fresh complaint evidence "for the purpose of determining whether or not the victim . . . was truthful when he testified here in court." The defendant's claim ignores the well-established principle that "[w]e are concerned with the impression left with the jury by the charge as a whole." Commonwealth v. Ramey, 368 Mass. 109, 114 (1975). See Commonwealth v. Doucette, 391 Mass. 443, 450 (1984); Commonwealth v. Sellon, 380 Mass. 220, 231-232 (1980). We do "not [scrutinize] bits and pieces removed from their context." Commonwealth v. Cundriff, 382 Mass. 137, 153 (1980), cert. denied, 451 U.S. 973 (1981).

The judge's instructions, viewed as a whole, explained the principles of fresh complaint evidence with care and precision. There was no error, much less a miscarriage of justice.

6. Voluntariness of the defendant's waiver. The defendant's final claim is that the judge erred in denying his motion to suppress his January 5, 1984, statements to Lt. McLaughlin. He argues that the statements should have been suppressed because he lacked the mental capacity knowingly, intelligently, and voluntarily to waive his Miranda rights during his interview with the police. The Commonwealth maintains that the defendant was not subjected to custodial interrogation and that, even if he were, he was properly informed of his Miranda rights and made a knowing, intelligent, and voluntary waiver of those rights.

With court approval, the defendant underwent psychological tests to assess his mental capacity. The results of these tests were presented at a pretrial suppression hearing where the psychologists who had administered the tests, the defendant, and Lt. McLaughlin testified.

Based on the testimony and evidence presented, the judge made the following findings of fact. At approximately 6:30 P.M. on January 5, 1984, Lt. McLaughlin telephoned the McDonough residence and asked if the defendant would come to the police station to talk about his relationship with the

Page 655

victim and his mother. The defendant arrived at approximately 9:50 P.M.; the lieutenant read him his Miranda rights prior to questioning. When asked if he understood his rights, the defendant replied several times that he did. The defendant testified that he understood that he could stop the questioning at any time but did not. He also stated that he wanted to answer any questions because he had "nothing to hide." The interview took forty-five minutes and included one break. He was not arrested after his interview.

The defendant's attorney hired Bruce Mermelstein, a psychologist, to conduct psychological tests to assess the defendant's capacity to understand and voluntarily waive his Miranda rights. Mermelstein testified that the only objective test administered, the Wechsler Adult Intelligence Scale, indicated that the defendant's full scale I.Q. was within the borderline range of intelligence and that he was "not mentally retarded." He opined that the defendant had "diminished cognitive capacity" and, therefore, did not have the mental capacity to understand his legal rights. On cross-examination, however, Mermelstein admitted that "diminished cognitive capacity" was just another way of saying that he was "just not very bright."

Based on those findings of fact, the judge made the following rulings of law. Since an individual's right to Miranda warnings is triggered by "custodial interrogation," Commonwealth v. Haas, 373 Mass. 545, 551 (1977), S.C., 398 Mass. 806 (1986), the initial issue is whether the defendant was subject to "questioning initiated by law enforcement officers after . . . [being] taken into custody or otherwise deprived of his freedom of action in any significant way." Commonwealth v. Bryant, 390 Mass. 729, 736 (1984), quoting Miranda v. Arizona, 384 U.S. 443, 444 (1966). The judge applied the factors outlined in Commonwealth v. Bryant, supra, [Note 17] and concluded that the defendant

Page 656

"reasonably could not have perceived the interrogation[ ] as coercive in nature." The police never threatened or abused the defendant. There was no mention of arrest, nor did an arrest occur. Therefore, the judge found that the statements attributed to the defendant were the product of a noncustodial interrogation. Since no Miranda warnings were necessary, whether the defendant voluntarily and intelligently waived his Miranda rights was irrelevant. The judge concluded, therefore, that the defendant's statement was admissible.

The judge further ruled that, even if the defendant's statements were the product of "custodial interrogation[ ]," they are nevertheless admissible if Miranda warnings were properly given and if a knowing, intelligent, and voluntary waiver was effected. The judge found that the defendant's waiver was made knowingly, voluntarily, and intelligently. As the judge indicated, the defendant was read his rights; stated that he understood those rights, singed the waiver portion of the Miranda card, and so testified at the suppression hearing. Although the defendant testified that he did not understand the Miranda rights at the relevant time, the judge correctly noted that he was not obligated to believe his testimony. Commonwealth v. Day, 387 Mass. 915, 919 (1983).

Furthermore, the judge found that the atmosphere of the interrogation was not threatening. After observing the defendant during his testimony and taking into consideration his educational and employment background, the judge was convinced beyond a reasonable doubt that he had sufficient mental capacity to understand his rights under Miranda, supra; that he did understand those rights; and that he effected a knowing, intelligent, and voluntary waiver of those rights when he signed the Miranda card on January 5, 1984.

"In reviewing a trial judge's determination that a voluntary waiver was made, the judge's subsidiary findings will not be

Page 657

disturbed, if they are warranted by the evidence, and his resolution of conflicting testimony will be accepted." Commonwealth v. Tabor, 376 Mass. 811, 822 (1978), quoting Commonwealth v. Santo, 375 Mass. 299, 303 (1978). Commonwealth v. Mahnke, 368 Mass. 662, 666 (1975), cert. denied, 425 U.S. 959 (1976). While the judge's ultimate findings and conclusions of law are open for this court to review, a finding of voluntary waiver is "entitled to substantial deference by this court." Commonwealth v. White, 374 Mass. 132, 138 (1977), aff'd by an equally divided Court, 439 U.S. 280 (1978). The judge properly ruled that Miranda warnings, although given, were not required. Further, even if the defendant's statements were viewed as the result of custodial interrogation, the evidence amply supports the judge's ruling that the defendant knowingly, intelligently, and voluntarily waived his Miranda rights. While the reviewing court must scrutinize the record with special care when the suspect has a diminished or subnormal mental capacity, Commonwealth v. Daniels, 366 Mass. 601, 606 (1975), such scrutiny in this case reveals nothing to criticize in the careful, thorough findings of the judge. There was no error.

Judgment affirmed.
