vs.

STEPHEN JASZEK.

MEMORANDUM AND ORDER PURSUANT TO RULE 23.0

After a Superior Court jury-waived trial, the defendant,

Stephen Jaszek, appeals from his convictions of four counts of

rape of a child and one count of indecent assault and battery on

a child. He argues that an excessive amount of prior bad acts

evidence was improperly admitted at trial and that the

prosecutor's closing argument was inflammatory, expressed

improper opinions, and vouched for witness credibility. For the

reasons set forth below, we affirm.

Background. We summarize the facts the judge could have

found, reserving certain details for later discussion. Jaszek

is a former elementary school music teacher. The victim -- an

adult by the time of trial -- was one of Jaszek's students when

she was in the third through fifth grades. For several months starting in the fall of the victim's fifth-grade year, Jaszek frequently told her to stay inside from recess for extra music lessons. It was during these extra lessons that the assaults occurred.

The victim did not like Jaszek as a teacher, describing him as "mad and loud," and recalling being scared of him. She testified to Jaszek's getting mad at her on at least two specific occasions when he assaulted her. She further testified that there were other times when Jaszek would be mad and yell at her without her knowing why.

The victim struggled with her mental health throughout her life, including experiencing selective mutism as early as third grade, attending an in-patient behavioral clinic as a teenager, and seeking counselling while in college. Medical records from various points in her life were introduced at trial, including notes on her memory and mental health.

The victim was a senior in high school when she first disclosed to a friend that she had been assaulted by her music teacher in elementary school. Then, in college, the victim began seeing a therapist regarding the assaults, and eventually law enforcement became involved.

Jaszek was subsequently indicted. The victim was the only witness who testified directly to the assaults, with other

witnesses providing varying degrees of corroboration. Of the Commonwealth's twelve witnesses, eight -- including the victim - - testified to Jaszek being an angry, scary, creepy, intimidating, or even violent person. Jaszek did not object to the vast majority of this testimony; when he did object, it was not on propensity grounds.1 Jaszek's defense was that the assaults had never happened and that the victim's memory and testimony were unreliable. On cross-examination of the victim and during closing arguments, defense counsel used portions of her medical records to challenge her credibility. The only witness for the defense was a cognitive psychologist who testified as an expert about memory distortion and the creation of false memories. Jaszek was convicted.

Discussion. As Jaszek did not object at trial on the grounds he now argues, we review to determine whether any error created a substantial risk of a miscarriage of justice. See Commonwealth v. Randolph, 438 Mass. 290, 297-298 (2002). That

question turns on whether we have "a serious doubt whether the result of the trial might have been different had the error not been made." Commonwealth v. LeFave, 430 Mass. 169, 174 (1999).

1. Propensity and prior bad acts. Jaszek argues that evidence of his having a bad temper, being angry, mistreating students, or breaking classroom objects was inadmissible propensity evidence. He further argues that, even if the evidence was otherwise admissible, the amount of such evidence was so unfairly prejudicial as to require a new trial. In the specific context of this jury-waived trial, and where Jaszek did not object on propensity grounds at any point, his arguments are unpersuasive.

Evidence of prior bad acts may not be introduced to prove the defendant's "bad character or propensity to commit the crime charged, but such evidence may be admissible if relevant for some other purpose" (citations omitted). Commonwealth v. Helfant, 398 Mass. 214, 224 (1986). One permissible purpose is "to show [the victim's] state of mind -- the explanation for her long-delayed disclosure of what had happened to her: fear of the defendant." Commonwealth v. McKinnon, 35 Mass. App. Ct. 398, 404-405 (1993). Nonetheless, "even if relevant, a judge must guard against the risk that evidence of prior bad acts will divert . . . attention from the charged acts," Commonwealth v. Dwyer, 448 Mass. 122, 129 (2006), and such evidence will not be

admitted if its probative value is outweighed by the risk of unfair prejudice to the defendant. See Commonwealth v. Crayton, 470 Mass. 228, 249 (2014).

Evidence of Jaszek's bad temper and poor treatment of his students was relevant for at least one nonpropensity purpose. Specifically, the evidence explained why the victim did not disclose the assault at the time, i.e., that she was scared of Jaszek and did not want him to be mad at her. Testimony from other witnesses about Jaszek's temper tended to corroborate the victim's testimony and so was relevant to her credibility and the accuracy of her memory, which were decisive issues here. See Commonwealth v. Kindell, 84 Mass. App. Ct. 183, 188 (2013) (witness's credibility is relevant issue in any case).

Thus, the evidence was admissible unless its prejudicial effect outweighed its probative value. In general, this risk is low in a jury-waived trial, because the judge is presumed to have applied correct principles of law and not to have relied on evidence for an improper purpose. See Commonwealth v. Milo M., 433 Mass. 149, 152 (2001); Commonwealth v. Dragotta, 89 Mass. App. Ct. 119, 128 (2016), S.C., 476 Mass. 680 (2017). Here, the amount of evidence about Jaszek's temper appears to have been excessive. But, even assuming that some of the testimony would have been excluded had there been an objection, Jaszek has not argued on appeal that the judge considered the evidence for an

improper purpose. Indeed, when discussing an objection at one point, defense counsel told the judge, "[t]here's no jury here, so I trust that you'll filter it out." As we see no unfair prejudice on this issue, any error in admitting the evidence created no substantial risk of a miscarriage of justice.2 2. Closing argument. Jaszek argues that the prosecutor made two main errors in his closing argument: (1) expressing a personal opinion on the evidence, including by vouching for the victim's credibility, and (2) appealing to the sympathies of the fact finder. While we agree that some portions of the prosecutor's argument were impermissible, we conclude that there was no substantial risk of miscarriage of justice.
