Sex Offender. Practice, Civil, Sex offender, Civil commitment, Report. Evidence, Sex offender, Expert opinion, Police report. Witness, Expert.

Petition filed in the Superior Court Department on February 5, 2019.

The case was tried before Michael J. Pineault, J.

Frederic G. Bartmon for the petitioner. Brian P. Mansfield for the Commonwealth.

TOONE, J. Because sexually dangerous person proceedings

seek to determine a person's propensity to commit sexual

offenses in the future, they are governed by a unique and

complex set of evidentiary rules, some prescribed by statute and

others based in common law. See McHoul, petitioner, 445 Mass.

Commonwealth v. Mackie, 100 Mass. App. Ct. 78, 84-85 (2021). In this case, the petitioner, Michael Tomaso, was civilly committed as a sexually dangerous person in 2009, and in 2019 he filed a petition pursuant to G. L. c. 123A, § 9, for release from his confinement. Following a trial in the Superior Court, a jury found that he remained sexually dangerous. At trial, each of the three psychologists called by the Commonwealth opined that, even though the petitioner was last convicted of a sexual offense thirty-five years ago, he was likely to sexually reoffend if released because he suffered from sexual sadism disorder, among other conditions. In arriving at their diagnoses of sexual sadism, all three experts relied predominantly, if not exclusively, on the alleged facts underlying dismissed sexual offense charges against the petitioner in 2002 and 2003. Because we cannot determine from the record whether those alleged facts were "independently admissible" under Department of Youth Servs. v. A Juvenile, 398 Mass. 516, 531 (1986), and Commonwealth v. Markvart, 437 Mass. 331, 337 (2002), due to the Commonwealth's failure to make such a showing and the judge's failure to hold a hearing on that issue as the petitioner had requested, it was error to admit the experts' sexual sadism disorder diagnoses. As we cannot say that this evidence had no impact on the jury's verdict, we

vacate the judgment, set aside the verdict, and remand this case to the Superior Court for a new trial.

Background. The petitioner was convicted of sexual offenses on three occasions. In 1977, he pleaded guilty to indecent exposure and threatening to commit a crime; the victims were his adult sister and her boyfriend. He was sentenced to two months in the house of correction, suspended, with one year of probation. In 1982, the petitioner grabbed a stranger's breast over her clothing in a public setting. He was convicted of sexual assault, and committed to the house of correction for eight months followed by one year of probation upon release. In 1991, the petitioner fondled a woman's breasts on a bus and kicked her father after the father confronted him. A jury convicted him of indecent sexual assault and battery on the woman and assault and battery by means of a dangerous weapon on the woman's father, and he was sentenced to eighteen months in the house of correction and three years of probation.

Other sexual offense charges did not result in convictions.

In 1978, the petitioner was charged with breaking and entering, assault with the intent to rape, and assault and battery related to an incident involving his girlfriend (1978 charges). Those charges were dismissed. In 2002, while traveling in Rhode Island, the petitioner allegedly forced a man to perform sexual acts on him, but the resulting sexual assault charge (2002

charge) was dismissed. In 2003, the petitioner assaulted a woman with a knife. Three years later, he pleaded guilty to assault by means of a dangerous weapon, carrying a dangerous weapon, and failure to register as a sex offender, and was sentenced to a term of from three to five years in State prison (2006 convictions); but the remaining charges against him -- rape, rape with force, unnatural rape, indecent assault and battery on a person over fourteen, kidnapping, and unnatural acts -- were dismissed (2003 charges).

In 2009, the petitioner was found to be a sexually dangerous person and committed to the Massachusetts Treatment Center pursuant to G. L. c. 123A, § 9. In 2019, he petitioned the Superior Court for examination and discharge, claiming that he was no longer sexually dangerous. In connection with his petition for discharge, he was examined by two qualified examiners, Dr. Katrina Colistra and Dr. Crystal Cookman. See G. L. c. 123A, §§ 1, 9. See Chapman, petitioner, 482 Mass. 293, 303-309 (2019) (discussing role of qualified examiners in discharge proceedings). Both qualified examiners submitted reports to the court, as did Dr. Gregg Belle on behalf of the Community Access Board (CAB).1

Prior to trial, the petitioner filed a series of motions in limine to exclude certain evidence at trial. One motion sought to exclude evidence of the dismissed 1978, 2002, and 2003 sexual offense charges. Another asked the judge to, among other things, exclude the opinions of the qualified examiners or, at least, conduct a voir dire "prior to any opinion being offered or allowed." In support of these motions, the petitioner asserted that "no information is available" regarding the 1978 charges, which were "dismissed for lack of prosecution, with consent of [the petitioner] and the complainant." The Commonwealth did not dispute that there was no available police report for the petitioner's 1978 charges. With respect to the 2002 charge, the petitioner attached a pleading from the Rhode Island Attorney General's Office stating that it had "reviewed this case and determined it is non-prosecutable for the following reason: Insufficient credible evidence. Complaining witness cannot be located." With respect to the dismissed 2003 charges, the petitioner attached a transcript of his plea colloquy for his 2006 convictions in which the prosecutor

§ 9. CAB witnesses are not independent experts, however, and their diagnoses cannot serve as the requisite clinical basis for a finding of sexual dangerousness. See Green, petitioner, 475 Mass. 624, 625, 629-630 (2016); Johnstone, petitioner, 453 Mass. 544, 551-552 (2009). See also Pierce, petitioner, 497 Mass. 140, 152 n.23 (2026).
