102 N.E.3d 369
Mass.2018Background
- William McDonagh was tried and convicted on two counts of aggravated statutory rape and three counts of indecent assault and battery on a child under 14 for sexual abuse of his son Colin; one dissemination-of-obscene-matter conviction was later reversed as insufficient.
- Colin testified that between 2009–2010 his father repeatedly touched him, forced oral sex, and showed photographs and videos of naked adults and children; images from the defendant’s computer were admitted at trial.
- The Commonwealth introduced by stipulation that McDonagh had been arrested (Oct. 25, 2010), admitted possessing child pornography, and later pleaded guilty—evidence admitted for limited purposes including corroboration and grooming.
- At the judge’s permission, the prosecutor argued in closing that the defendant’s admission to possessing child pornography showed his "state of mind"—that he was sexually attracted to children; defense objected but the judge allowed the argument.
- The SJC found the judge erred in permitting the prosecutor to argue state of mind/sexual attraction (a propensity inference) because the defendant’s state of mind was not at issue; nevertheless, the court held the error was not prejudicial and affirmed the convictions.
Issues
| Issue | Plaintiff's Argument (Commonwealth) | Defendant's Argument (McDonagh) | Held |
|---|---|---|---|
| Whether prosecutor could argue the defendant’s admission to possessing child pornography showed his "state of mind"/sexual attraction to children | The stipulation (admission) was admissible to show state of mind and corroborate victim; prosecutor may reasonably argue that fact in closing | Such an argument invited an impermissible propensity inference because state of mind was not a material issue; it suggested bad character | The judge erred in permitting the state-of-mind/attraction argument; it amounted to an improper propensity inference |
| Whether defense preserved the objection for appeal | Commonwealth contended objection was inadequate | Defense argued it sufficiently objected when contesting propensity/character use | Court held the objection was adequate in context and reviewed for prejudicial error |
| Whether the other-act evidence itself was admissible and for what limited purposes | Evidence admissible via stipulation for corroboration, grooming, opportunity, relationship, and timeline | Defendant accepted limited admissibility but contested broader uses (propensity/state of mind) | Other-act evidence was admissible for nonpropensity purposes (corroboration, grooming, opportunity) but not to prove propensity |
| Whether the prosecutor’s improper remark required reversal | Commonwealth argued error, if any, was harmless given strong evidence and limiting instructions | Defendant argued the propensity inference was prejudicial and required reversal | Court concluded error was harmless given corroborating evidence, the limited use of the improper remark in closing, and clear limiting jury instructions; convictions (except the conceded insufficient dissemination count) affirmed |
