1991 Austin yogurt shop murders

• 1. Introduction

  ›

  The 1991 Austin yogurt shop murders began with a fire. Shortly before midnight on Friday, the 6th of December 1991, a patrolman with the Austin Police Department radioed his dispatcher. Flames were coming from an I Can't Believe It's Yogurt! shop in Austin, Texas. Firefighters put out the blaze and went inside. They found four girls, all of them dead.

  The case that followed would stay open for more than three decades. It raises hard questions. Who would walk into a shop at closing time and do this to four teenagers? Why would young men confess to a crime that DNA later showed they had no part in? And what finally put a name to the person responsible?

  Amy Ayers was 13 years old, and she had come to the shop that Friday only to wait for a ride home. She was there with her friend Sarah Harbison, who was 15. Sarah's sister Jennifer, 17, worked behind the counter. Jennifer's coworker Eliza Thomas, also 17, was on shift that night as well.

  The arrangement was ordinary. When the shop closed at 11:00 p.m., Jennifer would take the two younger girls home. Two employees and two friends waiting on a lift made up the whole group inside.

  About an hour before closing, a stranger would ask to use the back restroom, and investigators spent decades trying to learn what that visit meant.

• 3. The Closing Hour

  ›

  About an hour before the 11:00 p.m. closing, a man was allowed into the public restroom at the back of the shop. Investigators believe he waited there and may have propped a rear door open. A couple who left just before closing said they saw two men at a table acting furtively. Those sightings were never tied to the crime.

  The scene told its own story. Each girl had been shot in the head with a .22 caliber lead bullet. Three of them, Sarah, Eliza and Jennifer, had been bound and gagged with their own clothing and badly burned by the fire.

  Amy was found in a different part of the shop. Her burns were second-degree and in places early third-degree, across 25-30 percent of her body. A cloth that looked like a sock was around her neck. The .22 bullet had missed her brain, but a second wound, from a .380 caliber bullet fired from an AMT Backup pistol, had done severe damage.

  At least three of the girls had been raped. From those assaults, police collected DNA from a male suspect. The killer most likely left through a back door that was later found unlocked.

  One of the original detectives read the scene as the work of adults. The organized method, the control over four victims and the fire set to destroy evidence all suggested experienced criminals rather than teenagers. The DNA from that night would sit in evidence for years, waiting for something to compare against.

• 4. A Flood of Suspects

  ›

  Kenneth McDuff, a known serial killer with a record of murders involving teenagers, was in the Austin area in 1991. Police soon ruled him out. He was executed on the 17th of November 1998.

  His name still turned up in the case again. Austin police admit that more than 50 people have confessed to the yogurt shop murders, and McDuff was one of them, on the day of his execution. In 1992, two Mexican nationals held by Mexican authorities also confessed. That claim was disputed and finally ruled false.

  A few days after the murders, a 16-year-old was caught at a nearby shopping mall carrying a weapon of the same caliber used in the killings. He first gave detectives promising information. After hard questioning, the detectives decided he was only trying to escape the gun charge. They eliminated him, along with three petty criminal friends he had named. None of the four was older than 17.

  Years later, a new detective would look back at a different group of teenagers from 1991, and the case would take a very different turn.

• 5. Confessions and Trials

  ›

  Several years after the murders, a new detective on the case argued that four teenagers from 1991 were credible suspects. They were by then in their twenties. Their names were Robert Springsteen, Michael Scott, Maurice Pierce and Forrest Welborn.

  A string of interrogations by various detectives produced confessions from some of the men. They said that all four had taken part. There was no record of what had been said to the men in the 1991 interrogations. That made it impossible to know whether detectives had fed details to the suspects, details that could later be repeated back as proof of guilt.

  One of the detectives in those sessions, Hector Polanco, had already been accused of coercing false confessions in an earlier case. It involved Christopher Ochoa and Richard Danziger, who were both released after 13 years in prison. Danziger was assaulted behind bars and suffered permanent brain damage.

  Scott and Springsteen were arrested in 1999. Their trials took place in 2001 and 2002 respectively. Prosecutors described the horror of the crimes in great detail but offered no hard evidence beyond the confessions. Both men were convicted of capital murder. Springsteen received a death sentence, and Scott received life in prison.

  In 2005, Governor Rick Perry commuted Springsteen's sentence to life, following the Supreme Court decision in Roper v. Simmons. Springsteen was 17 at the time. His conviction itself, however, was about to be challenged on constitutional grounds.

• 6. Convictions Unravel

  ›

  In 2006, the Texas Court of Criminal Appeals overturned Robert Springsteen's conviction on the ground of an unfair trial. In February 2007, the U.S. Supreme Court refused to reinstate it. In 2008, the same Texas court overturned both convictions. It ruled that prosecutors had violated the Confrontation Clause of the U.S. Constitution. They had used parts of the co-defendants' alleged confessions at trial, and defense lawyers could not cross-examine the men who made them.

  Science soon complicated the retrial. In March 2008, prosecutors submitted evidence for Y-STR testing, a method that looks only for male DNA and suits samples mixing female and male material. On the 20th of August 2008, defense lawyers asked for DNA testing of alternative suspects. No matches turned up against evidence found earlier that year.

  On Wednesday, the 24th of June 2009, Judge Mike Lynch freed Springsteen and Scott on personal bond. Travis County District Attorney Rosemary Lehmberg had asked to postpone Scott's trial, which was set for the 6th of July. At 2:50 p.m. that day, both men walked out of the Travis County Jail with their attorneys.

  Lehmberg said in a statement that the evidence pointed to a single unknown male. In her words, the science presented "one, and one only, unknown male donor." She added that she remained confident Scott and Springsteen were responsible, but she would not risk a trial before that man was identified.

  Forensic work then showed that the DNA found in one of the victims was not from Scott, Springsteen or the other two men named in the confessions. The prosecution gave up its plan for a retrial. On the 28th of October 2009, all charges against Scott and Springsteen were dismissed.

  Seven jurors from the original trials have since said they would not have voted to convict had that DNA evidence been available.

• 7. The Cold Case Years

  ›

  On the 23rd of December 2010, Austin officer Frank Wilson and his rookie partner, Bradley Smith, stopped a vehicle driven by Maurice Pierce in the northern part of the city. A brief chase on foot followed. Pierce struggled with Wilson, pulled a knife from his belt and stabbed the officer in the neck. Wilson survived. He drew his gun and shot Pierce dead.

  On the 8th of December 2021, the House Judiciary Committee passed a bill from Representative Michael McCaul. It lets families of cold case victims petition the federal government to reexamine cases older than three years. On the 5th of February 2022, Austin investigators announced that advanced DNA technology was bringing them closer than ever to solving the murders.

  On the 3rd of August 2022, Congress passed the Homicide Victims' Families' Rights Act of 2021, a law motivated by the yogurt shop murders. It aims to make federal law enforcement review cold case files with the latest technologies and investigative standards. It also states that families can request such a review from federal agencies.

  The case kept drawing writers and filmmakers. Scott Blackwood published the novel See How Small in 2015. In 2016, Beverly Lowry wrote the nonfiction book Who Killed These Girls? Cold Case: The Yogurt Shop Murders, and Corey Mitchell published Murdered Innocents. Crime Junkie and Generation Why each devoted a podcast episode to it. People Magazine Investigates covered it in 2023 in an episode titled "Who Killed Our Girls?"

  HBO released a five-part documentary, The Yogurt Shop Murders, in August 2025. A month later, Austin police held an announcement of their own.

• 8. The DNA Answer

  ›

  On the 26th of September 2025, Austin police announced that Robert Eugene Brashers had been linked to the yogurt shop murders by DNA. Brashers was a serial killer and serial rapist. Investigative genetic genealogy, led by CeCe Moore, had identified him in 2018. He died by suicide during a standoff with police in 1999.

  Three separate pieces of evidence pointed to him. Investigators developed a Y-STR DNA profile from swabs taken from three of the victims. It matched none of the earlier suspects, but it matched Brashers. Further testing found that the DNA profile under Amy Ayers's fingernails also matched him. A bullet casing recovered from a drain at the scene was consistent with patterns made by the gun he used to take his own life in 1999.

  On the 19th of February 2026, Judge Dayna Blazey formally exonerated Michael Scott, Robert Springsteen, Maurice Pierce and Forrest Welborn. They were declared factually innocent, and their charges were dismissed with prejudice.

  That ruling matters for money. Texas courts had earlier decided that Scott and Springsteen were not owed compensation because they had not proven they did not commit the crime. Under Texas law, a person whose conviction is overturned and who is also formally declared innocent can receive up to $80,000 for each year imprisoned. That outcome is uncommon, but the lawyers for Springsteen and Scott say they "remain hopeful."
