vs.

MIGUEL ANGEL RIVERA.1

MEMORANDUM AND ORDER PURSUANT TO RULE 23.0

After a jury trial, the defendant was convicted of thirty-

three offenses related to his physical and sexual abuse of three

minor children. After a jury-waived trial, the defendant was

convicted of being a habitual offender. On appeal, the

defendant raises nine claims. We vacate the judgment of

conviction on count eleven of the indictment, charging attempted

indecent assault and battery on a person over the age of

fourteen, and set aside the verdict on that count. All other

judgments are affirmed.

1. Expert testimony. The defendant claims that Dr.

Stephanie Block's unobjected-to testimony regarding delayed

disclosure by child sexual abuse victims requires reversal of his convictions of rape and indecent assault and battery. In particular, he claims that Dr. Block's testimony was not relevant, did not serve an explanatory purpose, distorted the fact-finding process, and improperly vouched for the child victims. We disagree.

"A trial judge has broad discretion with respect to the admission of expert testimony." Commonwealth v. Dockham, 405 Mass. 618, 628 (1989). "Expert testimony is required when the testimony concerns matters beyond the common knowledge of the jurors and will aid jurors in reaching a decision." Commonwealth v. Berendson, 73 Mass. App. Ct. 395, 399-400 (2008), citing Commonwealth v. Frangipane, 433 Mass. 527, 533 (2001). See Commonwealth v. Hinds, 487 Mass. 212, 220-222 (2021) (expert testimony admissible where relevant and scientifically reliable). We review a judge's decision to admit expert testimony for an abuse of discretion. Commonwealth v. Chism, 495 Mass. 358, 375 (2025).

Here, the defendant's abuse of the child victims began in 2016, and continued through 2020, when it was disclosed. The defense at trial was that the child victims had fabricated the allegations because they hated the defendant, for breaking their cell phones and yelling at them, and wanted him out of their

lives. In this light, the expert testimony on delayed disclosure was of assistance in assessing a victim witness's testimony and relevant because jurors may equate that delay with dishonesty.2 See Commonwealth v. Hudson, 417 Mass. 536, 540-541 (1994); Dockham, 405 Mass. at 629. Also, the jury were aware that Dr. Block never examined or saw the child victims, which mitigates the risk that the jury believed Dr. Block was vouching for the victims' credibility. See Commonwealth v. Federico, 425 Mass. 844, 849 (1997). See also Commonwealth v. Quinn, 469 Mass. 641, 647-648 (2014) (risk of improper vouching "especially acute" where expert treated victim). Finally, the judge further minimized any potential risk of misuse by giving limiting instructions immediately after Dr. Block's testimony, and again in the final charge. The instructions emphasized that credibility determinations and fact finding remained the exclusive province of the jury. See Commonwealth v. Richardson, 423 Mass. 180, 184-185 (1996).

2. Medical records of E.C. The defendant claims that the convictions of rape and indecent assault and battery of E.C., one of the child victims, must be reversed because E.C.'s medical records, which included her Sexual Assault Nurse Examiner (SANE) interview, were not properly redacted and repeatedly said that E.C. was the victim of sexual assault. Accordingly, the defendant claims the medical records, which were admitted in evidence without objection, created a substantial risk of a miscarriage of justice. We disagree.

Here, the parties agreed to admit in evidence E.C.'s medical records pursuant to G. L. c. 233, § 79, subject to specific redactions. The defendant's trial counsel expressly noted his satisfaction with the redactions. In this posture, we review for error, and if one occurred, whether it created a substantial risk of a miscarriage of justice. See Commonwealth v. Dargon, 457 Mass. 387, 397 (2010). There was neither error, nor an abuse of discretion. See Commonwealth v. Aviles, 461 Mass. 60, 72 (2011).

In general, hospital records are admissible in evidence pursuant to G. L. c. 233, § 79, to the extent they relate to a patient's treatment or medical history, but not to liability. We are to construe the statute "liberally" and permit the admission of medical records that directly and primarily relate

to diagnosis or treatment, even if those records incidentally touch on issues of liability. Dargon, 457 Mass. at 394; Commonwealth v. Dube, 413 Mass. 570, 573 (1992).

The defendant finds fault in E.C.'s medical records because they "repeatedly" refer to her as a "victim of sexual assault." The first challenged entries relayed E.C.'s descriptions of the causes of her injuries.3 However, even if these entries did not relate to medical diagnosis or treatment, and fell outside the purview of G. L. c. 233, § 79, there was no substantial risk of a miscarriage of justice from their admission. See Dargon, 457 Mass. at 397. The redacted records did not identify the defendant as the offender, nor did they express any opinion about his guilt. In this light, the records did not carry the imprimatur of the hospital's belief in the defendant's guilt. See Commonwealth v. DiMonte, 427 Mass. 233, 242 (1998).

The defendant also challenges an entry which stated, "[h]e threatened to smash her phone and tell her mother." The Commonwealth properly concedes that this entry does not relate to E.C.'s treatment or medical history. See G. L. c. 233, § 79. However, because the defendant relied on this evidence to

support his defense that the child victims hated him and wanted him out of their lives because he destroyed their cell phones and had a terrible temper, there is no risk that justice miscarried as a result of the improper entry. Also, this entry was cumulative of testimony that the defendant would break things, including the child victims' cell phones.

3. Jury instruction on the defendant's arrest and detention. The defendant further claims that an unobjected-to jury instruction erroneously told the jury that they could use the fact of the defendant's arrest and subsequent detention as evidence of his guilt.4 We disagree.

The only authority the defendant cites in support of this claim is Commonwealth v. Drayton, 386 Mass. 39, 45 n.4 (1982), for the proposition that indictments are not evidence. While that is undeniably true, it does little to support the defendant's claim here. The defendant's arrest and custodial status were directly relevant to the witness intimidation counts, where he was alleged to have committed those crimes after his arrest while in custody. See Commonwealth v. Facella, 478 Mass. 393, 401 (2017). In fact, they were closely intertwined with his motive, intent, state of mind, and plan.

Most importantly, the judge carefully instructed the jury, both contemporaneously with testimony regarding the defendant's arrest and in the final charge, that the defendant's arrest and detention could be considered only for limited, nonpropensity purposes. At no point did the judge suggest that either was evidence of the defendant's guilt, but rather stated the contrary. There was no error, and thus, no risk that justice miscarried.
