The long-running investigative program 20/20 will air a new two-hour episode titled “Home Alone” on Friday, October 2, 2026. Reported by correspondent John Quiñones, the investigation explores the 2015 murder of Allison Feldman and the scientific breakthrough that eventually ended a years-long search for her killer.
The episode is scheduled to premiere on ABC News. Viewers who miss the linear broadcast can stream the program on Hulu and Disney+ beginning the following day, Saturday, October 3, 2026.

The Murder of Allison Feldman
The case began in February 2015, when 31-year-old Allison Feldman was found dead inside her Scottsdale, Arizona, home. Feldman had been brutally beaten and sexually assaulted. The discovery sparked a massive local investigation, but despite Scottsdale police interviewing more than 100 potential suspects, no immediate match for the DNA found at the scene was identified.
For years, the case remained unsolved. The investigation eventually turned to forensic familial DNA testing, a method that looks for partial matches in genetic databases to identify relatives of an unknown suspect. This technique allowed investigators to narrow their focus and eventually identify the person responsible for Feldman’s death after traditional leads had been exhausted.
Advanced Forensics and Expert Contributors
The “Home Alone” episode features insight from David and Kristen Mittelman of Othram Labs, who have joined the program as contributors this season. Othram Labs specializes in forensic genetic genealogy, the specific science that has become a cornerstone in resolving high-profile cold cases across the country. Their expertise provides a technical perspective on how modern DNA processing can overcome the limitations of older forensic systems.
The program details the timeline from the initial crime scene to the moment law enforcement finally secured an arrest.
