State v. Anthony L., 179 Conn. App. 512

Defendant (uncle) was charged with sexual assault in the first degree, risk of injury to a child, and sexual assault in the third degree for repeatedly digitally penetrating his niece between May 23, 2002 and December 31, 2003; last alleged act occurred in December 2003 in Massachusetts.
Complainant testified to earlier uncharged abuse (prior to May 23, 2002) in detail and to repeated, similar forceful digital penetration during the charged period (more than once, locations included car, couch, bedroom).
Defendant moved to exclude evidence of uncharged misconduct (incidents before May 23, 2002 and the act in Massachusetts) as unduly prejudicial; trial court admitted that evidence to prove motive/intent and gave three cautionary instructions to the jury.
Jury convicted on all counts; defendant appealed arguing (1) insufficiency of evidence (complainant’s testimony lacked specificity for the charged period) and (2) erroneous admission of uncharged misconduct because it was more prejudicial than probative and effectively the main evidence of guilt.
Appellate court evaluated sufficiency under the Stephen J. R. three-factor approach (kind of act, number of acts, general time period) and reviewed admission of other-acts evidence under Connecticut’s relevance/materiality and probative-prejudicial balancing standards.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Sufficiency of evidence for first-degree sexual assault and risk of injury (digital penetration)	State: Complainant described digital penetration during charged period, frequency (>1), force, and age (13–15), satisfying elements	Defendant: Testimony for charged period lacked specific instances/dates; relied on uncharged acts for detail, so evidence insufficient	Held: Affirmed — testimony sufficiently specific (digital penetration, force, multiple occurrences, general time period) to support convictions
Admissibility of uncharged misconduct (prior acts and out-of-state act)	State: Prior and subsequent acts involving same complainant and same nature are admissible to show motive/intent and corroborate pattern; probative value outweighs prejudice; limiting instructions given	Defendant: Detailed uncharged testimony was more prejudicial than probative and was effectively the primary evidence of guilt	Held: Affirmed — trial court did not abuse discretion; evidence was material to motive/intent, not unduly prejudicial, and limiting instructions mitigated risk
