Allison Feldman Murder: How Familial DNA Helped Solve the 2015 Killing of an Arizona Woman

For more than a decade, the murder of Allison Feldman remained an unresolved case that haunted her family and investigators in Arizona. The 31-year-old medical sales representative was found dead inside her Scottsdale home in February 2015. It would take years of investigation, a controversial DNA search and a lengthy legal battle before the man convicted of her killing was brought to justice.

Feldman was a University of Arizona graduate who had built a life and career in Arizona. Friends and family described her as a loved and valued part of their lives. When they suddenly stopped hearing from her, they became concerned that something was wrong.

On February 18, 2015, her boyfriend went to check on her at home and discovered her body. Investigators determined that she had suffered fatal head injuries. Evidence at the scene indicated that she had also been sexually assaulted, and authorities believed someone had attempted to clean up after the attack.

The investigation initially produced no immediate arrest. Detectives examined potential suspects and followed leads, but the case remained unsolved for more than three years.

A breakthrough came in 2018, when investigators used familial DNA testing to identify a potential suspect. Rather than finding a direct match to a known offender, authorities found that DNA evidence collected from the crime scene was similar to the DNA profile of a suspect’s relative.

That lead pointed investigators toward Ian Mitcham, a Phoenix-area man whose DNA was subsequently matched to evidence from Feldman’s home. He was arrested and charged in connection with her murder.

The DNA evidence later became the focus of a complicated legal dispute. Mitcham’s defense challenged the way authorities had obtained and retained his DNA sample, arguing that it should not have been used in the investigation. The case went through years of court proceedings before the Arizona Supreme Court allowed the evidence to be used at trial.

In April 2026, a jury found Mitcham guilty of first-degree murder, sexual assault and second-degree burglary. Prosecutors argued that he had entered Feldman’s home, sexually assaulted her and beaten her to death. The defense disputed the accusation and argued that investigators had focused too heavily on the DNA evidence. Authorities have not established a motive for the killing.

The sentencing proceedings brought another difficult chapter. In May 2026, jurors could not reach a unanimous decision on whether Mitcham should receive the death penalty, resulting in a mistrial in the penalty phase. He received a prison sentence for the sexual assault and burglary charges, while prosecutors planned to pursue another sentencing proceeding on the death penalty. He has also appealed his conviction.

Feldman’s father, Harley, spent years following the case and advocating for justice for his daughter. He also helped support other families affected by homicide and promoted the use of familial DNA to help solve crimes. He died in April 2026, only weeks after the guilty verdict.

For Feldman’s loved ones, the conviction represented a major development after years of waiting, but it could never undo their loss. Her case also highlighted how DNA technology can help solve old crimes, while raising important questions about privacy, evidence collection and the legal safeguards that govern investigations.
