DNA Solves 3-Year Arizona Murder Mystery
3 Oct
Summary
- Allison Feldman found deceased in her Arizona home in February 2015.
- Killer identified over three years later using advanced DNA testing.
- Ian Mitcham was convicted in April 2026 for the 2015 murder.

The tragic murder of Allison Feldman, a 31-year-old resident of Scottsdale, Arizona, was initially a perplexing mystery. Feldman was discovered deceased in her home by her then-boyfriend on February 18, 2015, one day after she was last heard from. The crime scene indicated a struggle, and an autopsy revealed she had been sexually assaulted and died from blunt force trauma and asphyxia on February 17, 2015.
The investigation faced challenges, with numerous suspects initially considered. Over three years later, authorities utilized familial DNA testing with a sample from the crime scene. This led investigators to Ian Mitcham, whose DNA matched the crime scene sample. Mitcham was arrested on April 10, 2018, and charged with burglary, rape, and murder.
Ian Mitcham's trial commenced in late 2025, with the prosecution arguing he sexually assaulted and murdered Feldman on February 17, 2015, before attempting to clean the scene. The defense maintained his innocence, questioning the DNA evidence collection. On April 9, 2026, Mitcham was found guilty of first-degree murder, sexual assault, and second-degree burglary. Sentencing followed in May 2026 for the lesser charges.
