HBO has set August 3 for the debut of The Yogurt Shop Murders, a four-part true-crime documentary airing Sundays at 10 p.m. ET/PT and streaming on Max. Directed by Austin-based filmmaker Margaret Brown and backed by A24 and Fruit Tree, the series will roll out weekly through August 24.
The project revisits the still-unsolved 1991 slayings of Eliza Thomas, Jennifer Harbison, Sarah Harbison and Amy Ayers, whose bodies were discovered in a torched “I Can’t Believe It’s Yogurt!” shop on Austin’s north side.
Brown weaves archival news footage, interrogation tapes and fresh interviews with relatives, detectives and legal experts to re-examine a case that shattered the city’s self-image and remains open more than three decades later.
Investigators initially focused on four teenage boys; two confessed under intense questioning and spent nine years in prison. DNA testing in 2008 excluded them, and prosecutors dropped the charges the next year, leaving families and suspects alike in limbo. The series explores how false confessions materialized and why no physical evidence has ever pointed to a definitive killer.
Speaking after an early screening at South by Southwest, Brown said her fascination began while living in Austin in the late ’90s, when billboards pleaded for answers. “Nobody knew what happened,” she told the crowd. At the same event, Eliza Thomas’s sister Nora called the gathering “an act of collective care” and thanked viewers for keeping the victims’ memories alive.
Police maintain that the cold case remains active; relatives hope renewed attention—and modern forensic tools—may finally pinpoint whoever staged the fire that December night. For viewers, Brown promises a study in grief, memory and resilience as Austin confronts an enduring scar on its history.
