The four-episode series focuses on the 1991 murders of Eliza Thomas, Jennifer Harbison, Sarah Harbison and Amy Ayers at a yogurt shop in Austin, Texas.

In 1991, four teenage girls, Eliza Thomas, 17, Amy Ayers, 13, and sisters Jennifer Harbison, 17, and Sarah Harbison, 15, were brutally murdered at an I Can’t Believe It’s Yogurt! shop in Austin, Texas.

The case is the subject of a new HBO series, The Yogurt Shop Murders. Directed by Margaret Brown and produced by A24 and Fruit Tree, the four-part true crime documentary delves into the many developments that have arisen in the decades since, including the arrest (and eventual release) of the case's four prime suspects.
