The 1991 yogurt shop murders in Austin remain unsolved after four teenage girls were bound, shot, and burned in a frozen yogurt shop. Despite initial confessions from Robert Springsteen and Michael Scott that led to convictions, their cases were overturned due to improper handling of evidence. Unidentified male DNA found at the scene has never matched any known suspects. More than three decades later, the case still haunts Austin as investigators await new DNA technology that might finally reveal the truth.
A Night of Horror: The Crime Scene at “I Can’t Believe It’s Yogurt”
devastating crime scenes. As firefighters battled the blaze at the I Can’t Believe It’s Yogurt! shop, they discovered the unthinkable—four teenage girls, bound, naked, and gagged.
Investigators determined that Eliza Thomas, Jennifer Harbison, Sarah Harbison, and Amy Ayers had been executed, each shot in the head before the perpetrators used lighter fluid to set the shop ablaze. The fire severely compromised evidence, washing away critical clues as water from firefighters’ efforts flooded the site.
The methodical nature of the crime—using two different firearms and attempting to destroy evidence—suggested a calculated attack that would haunt Austin for decades. The Austin murders have drawn comparisons to other unsolved violent crimes, and the calculated nature of the crime continues to disturb investigators and the public alike.
The Four Young Victims: Lives Cut Tragically Short

Behind the cold forensic details of Austin’s darkest crime lay four vibrant young lives, each with dreams and futures violently stolen that December night.
Jennifer Harbison, 17, worked at the yogurt shop in the strip mall alongside her friend Eliza Thomas, also 17. Jennifer’s younger sister Sarah Harbison, 15, and their friend Amy Ayers, 13, had stopped by that evening. None could have imagined the horror awaiting them.
The assailants forced them into a storage room, where this innocent gathering became a capital murder scene. The perpetrators shot each girl execution-style before setting a fire meant to destroy evidence. Crime scene investigators faced an overwhelming challenge amid the charred remnants.
You’ll never know how much was lost—not just evidence, but potential, laughter, and futures that would never come to pass.
The tragedy echoed the somber history of the Battle of Gonzalez in Texas, where violence similarly shattered lives unexpectedly.
Initial Investigation and Dead Ends: 1991-1999
As the horrific crime scene went cold, Austin police faced mounting pressure to solve what quickly became known as the yogurt shop murders—the most brutal crime in the city’s modern history.
Within days, investigators questioned four teenage suspects—Springsteen, Scott, Pierce, and Welborn—but released them when evidence fell short. The fire had destroyed essential forensic material, hampering detectives’ efforts to find the killers who had bound and shot the four girls.
For eight years, the case languished with few leads until 1999, when a breakthrough seemed imminent: Springsteen and Scott confessed. Yet both quickly recanted, claiming police coercion. DNA testing couldn’t conclusively link them to the crime scene, and their convictions were eventually overturned. Meanwhile, grand juries declined to indict Pierce and Welborn, leaving the case frustratingly unresolved.
The community’s outrage over the unresolved murders paralleled the Texian unrest that had fueled significant historical conflicts in Texas’s past.
Confessions and Controversy: The Arrests of Springsteen and Scott

The 1999 arrests of Robert Springsteen and Michael Scott marked a stunning development in the long-stalled yogurt shop murder investigation. Both men confessed to killing the four teenage girls, with Springsteen subsequently receiving the death penalty and Scott getting a 99-year sentence for capital murder.
Their convictions didn’t last. The Texas Court of Criminal Appeals later overturned both, citing the improper use of their confessions against each other. Questions immediately surfaced about the reliability of these admissions, which they both recanted. Critics questioned whether the suspects had been influenced by media reports or leading interrogation tactics.
The case exposed serious investigative flaws. With an overwhelming number of tips and false confessions after the murders, and a compromised crime scene, authorities struggled to produce evidence that conclusively linked any suspect to the brutal killings.
Trial, Conviction, and Reversal: Legal Battles and Overturned Verdicts
Robert Springsteen and Michael Scott’s journey through the justice system proved as controversial as their confessions. In separate trials, Travis County prosecutors secured convictions against both men. Springsteen received a death sentence, while Scott was sentenced to 99 years in prison.
Meanwhile, charges against Maurice Pierce and Forrest Welborn were dropped after grand juries declined to indict them. The legal foundation of the case began crumbling when courts scrutinized the way the confessions were obtained. Eventually, both convictions were overturned due to constitutional violations related to the use of their statements.
More than 30 years later, the case remains cold. The reversal of these verdicts left four murders unsolved and a city still longing for justice.
The DNA Mystery: Unidentified Genetic Evidence
Uncovering a partial male DNA profile at the crime scene seemed like a breakthrough—but it only deepened the mystery. The sample didn’t match any of the original suspects, nor over 100 other men subsequently tested, including law enforcement personnel.
A potential match surfaced in a public DNA database in 2017, briefly renewing hope. However, it was later revealed the match stemmed from an FBI research submission, not an investigative lead. Advanced DNA testing in 2020 created further complications, showing the sample no longer matched the original profile due to limitations in interpretation or degradation.
Today, investigators are preserving what’s left of the DNA sample, awaiting technological advances that could finally identify the source. After 30 years, this fragment remains the strongest remaining clue in Austin’s most notorious cold case.
Alternative Theories and Overlooked Suspects
While DNA evidence remains the central focus, some witness accounts have raised questions about alternative suspects. Credible witnesses reported seeing two men exit the yogurt shop shortly before the girls were murdered—a detail inconsistent with the theory involving four teenage boys.
Supporting this theory were overlooked items like an unopened Coke can and a misplaced napkin holder, potentially tied to the unidentified men. Some investigators believe one man may have surprised Eliza Thomas while she retrieved a soda, setting off the deadly chain of events.
Even Dick Ellis, a former law enforcement official involved in the case, has suggested this theory merits renewed focus. Defense attorneys argued these suspects were never adequately pursued, raising concerns about whether the real killers escaped justice.
Impact on Austin: How the Case Changed a City

Before December 6, 1991, Austin was considered a safe, family-oriented college town. The brutal murders of four young girls working and hanging out at a yogurt shop shattered that perception and marked a turning point in the city’s collective psyche.
Law enforcement heightened its presence, and the community became more guarded. The lack of conclusive evidence—and the eventual reversal of convictions—undermined public faith in the justice system. Parents who once encouraged independence began enforcing strict curfews and greater oversight.
Yet the tragedy also brought unity. Calls to “Remember the Yogurt Shop Murder Victims” became a rallying cry for community accountability, and a symbol of the fight for justice. The impact lingers as a constant reminder of vulnerability and resilience in the face of tragedy.
The Search for Justice: Modern Efforts to Solve the Decades-Old Case
More than three decades after the tragedy that transformed Austin, the yogurt shop murders remain unsolved—but efforts to crack the case continue. The killing of four teenage girls at I Can’t Believe It’s Yogurt! remains one of Texas’s most chilling cold cases.
Today, the key lies in a partial DNA profile recovered from the crime scene. Despite testing over 100 individuals, including known suspects and law enforcement, no match has been confirmed.
Congressman Michael McCaul and local investigators remain hopeful, as advancements in forensic science may one day yield results from the fragile DNA evidence. The FBI’s 2017 database entry offered no leads, but the search continues. Austin still waits for closure—for a moment when technology and justice finally converge to solve this haunting case.
