State v. Argueta, 469 P.3d 938

Background

Late-night incident: A.C. awoke half-asleep to someone touching her; J.W. confronted a man (Argueta) fleeing the apartment and neighbors detained him until police arrived.
At the scene Argueta was given Miranda warnings, invoked his rights, then nevertheless made an unsolicited denial/brief explanation that he had met A.C. at a bar and found keys in the door.
Charged with burglary and forcible sexual abuse; at trial Argueta expanded his account claiming he visited to collect an old $20 debt and entered to put keys inside as a "good deed."
The court admitted two prior bad-act items under Rule 404(b): a 2010 trespassing conviction and a 2014 peeping incident (limited to rebut intent), and the jury convicted Argueta.
On appeal and certiorari Argueta challenged (1) prosecutor’s cross-examination/closing comments about omissions between his on-scene statement and trial testimony (a Doyle claim), (2) admission of the trespassing incident under the doctrine of chances, and (3) admissibility of the peeping incident (preservation issue).
The Utah Supreme Court affirmed: it held the peeping objection was unpreserved, declined to definitively decide the Doyle/Charles line issue, and found any assumed constitutional or evidentiary errors harmless beyond a reasonable doubt.

Issues

Issue	State's Argument	Argueta's Argument	Held
Whether prosecutor’s references to facts omitted from Argueta’s on-scene statement violated his Fifth Amendment right to remain silent (Doyle claim)	Cross-examination and argument legitimately impeached prior voluntary statements; even if Doyle implicated, any error was harmless beyond a reasonable doubt	Comments impermissibly drew adverse inference from invocation/silence after Miranda and thus violated Doyle	Court assumed arguable Doyle error but found it harmless beyond a reasonable doubt given overwhelming contrary evidence; did not resolve constitutional question definitively
Whether admission of the 2010 trespassing conviction was proper under the doctrine of chances (Rule 404(b))	Evidence was admissible to rebut Argueta’s claim of innocent intent in entering the apartment	Admission was erroneous and prejudicial because the events were not shown sufficiently similar or statistically improbable	Court could not definitively resolve doctrinal application due to insufficient articulation by State, but held any error was harmless given the overall evidence against Argueta
Whether the 2014 peeping incident should have been excluded under Rule 403 as unreliable eyewitness ID	Evidence was admissible to rebut intent and identity; trial court allowed defense to call an expert on ID reliability	Eyewitness ID was unreliable and should have been excluded under Rule 403; alternatively, trial court erred	Court held the specific Rule 403/unreliability challenge was unpreserved (defense below argued only trial burden and confusion); thus the claim was forfeited on appeal
