G063237
Cal. Ct. App.Feb 6, 2025Background
- Heather Briana Swenson was convicted by a jury of robbery, vehicle theft, elder abuse, and simple assault in connection with an incident involving her elderly friend, Alex R.
- The jury acquitted Swenson of kidnapping and aggravated assault; she admitted prior serious felony convictions.
- Swenson received a six-year prison sentence, execution suspended, and was placed on formal probation for two years.
- Before trial, Swenson moved to dismiss the case arguing destruction of exculpatory evidence by police, and to suppress her police statements alleging an invalid Miranda waiver due to mental state concerns.
- The trial court denied both motions.
- Swenson appealed, challenging denial of both her Trombetta/Youngblood motion (regarding evidence preservation) and her Miranda-based suppression motion.
Issues
| Issue | Appellant's Argument | Respondent's Argument | Held |
|---|---|---|---|
| Motion to Dismiss for Destruction of Evidence | Police knowingly destroyed exculpatory evidence (Alex’s cellphone data) that could aid defense | No evidence of exculpatory content; no bad faith by police; phone had missing SIM and was not defendant’s property | Denied; no bad faith or apparent exculpatory value, substantial evidence supports ruling |
| Motion to Suppress on Miranda Grounds | Waiver was not knowing, intelligent, or voluntary due to mental illness and disorganized thinking | Swenson understood warnings, affirmed understanding, no evidence of incapacity or coercion | Denied; waiver valid under totality of circumstances, mental condition alone insufficient |
