Yogurt Shop Murders: New DNA Evidence and Cold Case Investigation

The 1991 Yogurt Shop Murders

• 🎯 On December 6th, 1991, four teenage girls—Jennifer and Sarah Harbison, Eliza Thomas, and Amy Ays—were murdered in an Austin, Texas yogurt shop.
• 🔪 The crime involved a robbery, fire, and murder, with the victims gagged, tied up, and shot in the head, and the shop subsequently set on fire.
• 💔 The case has deeply impacted the victims' families, with many struggling with grief, insomnia, and the ongoing lack of closure for over 30 years.

Initial Investigation and False Leads

• 🔍 Lead investigator Jon Jones and his team pursued numerous leads, including hypnosis, polygraphs, and extensive suspect interviews.
• 🕵️‍♂️ Early suspects, including Maurice Pierce and three acquaintances, were questioned but released due to insufficient evidence.
• 🎭 The investigation also explored a counterculture group and individuals connected to the occult, and a sketch of a person of interest led to a dead end with confessions that did not match crime scene details.
• 🗣️ Over the years, six false confessions were obtained, highlighting the difficulty in solving the complex case.

The 1999 Arrests and Convictions

• 🚨 In October 1999, four men—Maurice Pierce, Forest Wellborn, Michael Scott, and Robert Springsteen—were arrested, the same individuals initially questioned shortly after the murders.
• ✍️ New confessions from Michael Scott and Robert Springsteen became the primary evidence, despite defense claims of coercion.
• ⚖️ In 2001, Robert Springsteen was convicted of capital murder and sentenced to death, and Michael Scott was convicted and sentenced to life in prison.

Overturned Convictions and DNA Breakthroughs

• 🏛️ In 2016, both Scott and Springsteen's convictions were overturned on constitutional grounds due to the violation of their right to confront accusers.
• 🧬 In 2009, YSTR DNA testing on a vaginal swab from one victim revealed a male DNA profile that did not match any of the four original suspects, including Scott and Springsteen.
• 🔬 Despite efforts in 2017 and 2020 to match the YSTR DNA to a federal offender database, the FBI sample was conclusively excluded, leaving the DNA source unidentified.

Ongoing Search for Justice

• ❓ The case remains unsolved, with the DNA evidence being the most critical lead, though its source is still unknown.
• 💔 The victims' families continue to live with the pain and uncertainty, with some, like Eliza Thomas's mother, passing away with unresolved questions.
• 🎗️ Investigator Jon Jones, who suffers from PTSD, remains hopeful that the case can eventually be solved for the families' sake, keeping the shirt he wore the night of the murders as a promise to be worn only when the case is closed.
• 💡 A recent case update in September 2025 identified Robert Eugene Brashers, a deceased serial killer, as a new suspect based on new DNA evidence linking him to the case.
