Director Margaret Brown joins Killer Thriller Docu to discuss HBO's The Yogurt Shop Murders, the gripping documentary series exploring the 1991 murders of four teenage girls in Austin, Texas, and the decades-long search for justice.

Margaret shares what drew her to one of Texas' most haunting unsolved cases, the emotional responsibility of telling a story rooted in unimaginable loss, and how false confessions and flawed interrogation tactics led to wrongful convictions.

She also reveals what happened when the unimaginable occurred: just weeks after the documentary premiered, the case was finally solved - prompting the series to return for a stunning final episode.
