551 P.3d 416
Utah Ct. App.2024Background
- In 1988, Peggy Sue Case disappeared after attending a party with her boyfriend, Michael Kufrin; she was last seen with him.
- Police investigations at the time were inconclusive; Peggy’s body was not found until 2017, buried in a root cellar at their former residence.
- Evidence included differing stories told by Kufrin about Peggy’s whereabouts, disposed decaying items linked to Peggy, and bank documents showing potentially forged checks draining Peggy’s account.
- Expert testimony at trial concerned decomposition timelines, which was material to whether Peggy could have been moved and buried in the root cellar within a given timeframe.
- At trial, a detective briefly referenced Kufrin’s “previous cellmates”; Kufrin moved for a mistrial, which was denied. He was convicted of murder and appealed on multiple grounds.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Denial of Mistrial (cellmate comment) | Mention unfairly suggested prior criminal history | Reference was brief, unsolicited, and innocuous | No abuse of discretion, motion properly denied |
| Admission of Expert Testimony (decomposition) | Testimony unreliable; not based on sufficient facts/data | Opinion based on extensive experience and literature | No abuse; testimony admissible |
| Ineffective Assistance (failure to object) | Counsel should’ve made Rule 403 objection to relationship testimony | Testimony probative; objection would be futile | No deficiency; claim fails |
| Cumulative Error | Individual and collective errors deprived fair trial | No errors, thus no cumulative effect | No cumulative error identified |
