In December 1991, police in Austin, Texas, found four teen girls murdered in a yogurt shop. Now an Alabama filmmaker’s look at the seemingly random crime and its convoluted aftermath is set to debut at a major film festival.

Mobile native Margaret Brown recently announced that “The Yogurt Shop Murders,” a series she directed for A24 and HBO, will premiere in March at the South by Southwest Film Festival.

Brown’s past projects include the documentary films “Order of Myths,” about racial lines in Mobile’s Mardi Gras celebrations; “The Great Invisible,” about the Deepwater Horizon Disaster; and “Descendant,” an award-winning project that drew new attention to the story of the slave ship Clotilda and the Africatown community. This will be her first time directing a series and her first project in the true-crime genre.

According to a description on the festival website, “The Yogurt Shop Murders” series “dives into the immense trauma left by the crime and details the maze of the investigation. Interviews with family members, investigators, and suspects, along with a trove of archival footage, reveal a crime scene ravaged by fire and water, an overwhelmed police department, and a terrified city. Countless twists and turns uncover false confessions, overturned convictions, and endless speculation. The central question of the series revolves around the experience of loss and the ways in which we bear its scars.”

The case became a subject of long-term interest in part because the crime scene was gruesome and the results of multiple investigations were inconclusive: Two men were convicted but those convictions later were overturned. According to the Internet Movie Database, the case has been the subject of episodes of “People Magazine Investigates” and “48 Hours.”

The SXSW Fest takes place March 7-15. According to the festival website, “The Yogurt Shop Murders” will be screened at noon March 10. The project is being produced by Fruit Tree, a production company co-founded by actress Emma Stone and her husband, comedian and director Dave McCary.

No release date has been announced for “The Yogurt Shop Murders.”
