1991 Austin Yogurt Shop Killings
Unsolved Quadruple Homicide
CLASSIFICATION: Mass Murder
LOCATION
Austin, Texas
TIME PERIOD
December 6, 1991
VICTIMS
4 confirmed
On December 6, 1991, at approximately 11:00 PM, a quadruple homicide occurred at an I Can't Believe It's Yogurt! shop in Austin, Texas, resulting in the deaths of four teenage girls: 13-year-old Amy Ayers, 17-year-old Eliza Thomas, 17-year-old Jennifer Harbison, and Jennifer's 15-year-old sister Sarah. The victims were shot execution-style, with evidence indicating at least one had been raped, and the crime scene was later set on fire to destroy evidence. A male suspect was seen in the shop shortly before closing, and DNA from an unknown male has been collected, with a Y-chromosome match found in an FBI database, but the identity remains undisclosed due to privacy laws. The case remains unsolved, with the Austin Police Department continuing to investigate leads and analyze evidence.
Theories surrounding the 1991 Austin yogurt shop killings include the belief that the perpetrator was an experienced adult criminal rather than teenagers, given the organized method of operation and ability to control the victims. Some speculate that the man who used the bathroom prior to the crime may have been involved, as he was seen acting suspiciously. Additionally, the presence of DNA from an unknown male linked to one of the rapes has led to ongoing speculation about potential suspects or connections to other crimes.
A Night of Terror: The 1991 Austin Yogurt Shop Killings
The Crime
On the chilly evening of December 6, 1991, the bustling city of Austin, Texas, was about to be thrust into the throes of a horrific crime that would remain unsolved for decades. The scene was an I Can't Believe It's Yogurt! shop, where four teenage girls met a brutal end. The victims: 13-year-old Amy Ayers, 17-year-old Eliza Thomas, 17-year-old Jennifer Harbison, and Jennifer's 15-year-old sister, Sarah Harbison. On that fateful night, Jennifer and Eliza were working at the shop, while Sarah and her friend Amy awaited a ride home with Jennifer after closing time, scheduled for 11:00 p.m.
An hour before the shop was set to close, an unidentified man, who had been attempting to hustle customers, was allowed to use the restroom. He lingered suspiciously, possibly jamming a rear door open. As closing time approached, witnesses recalled seeing two men acting furtively at a table. At precisely 11:00 p.m., Jennifer locked the front door, marking the last time anyone saw the girls alive.
Discovery and Initial Investigation
As midnight approached, a police patrolman noticed flames licking at the yogurt shop. The discovery was chilling: the bodies of the four girls lay inside, victims of a horrific massacre. Each girl had been shot execution-style in the head, and one had been raped. Evidence indicated the killers used a .22 and a .380 pistol, and they likely made their escape through the back door, left unlocked. The crime's meticulous nature suggested the work of an experienced criminal rather than impulsive teenagers.
The Austin Police Department recovered DNA from an unknown male, a crucial piece of evidence in the investigation. Despite this, the DNA's Y-chromosome match in an FBI database remained anonymous, with thousands of potential matches. The investigation hit a wall, despite the initial flurry of activity and numerous persons of interest, including a 15-year-old with a .22 caliber gun found days later. However, he and three friends were eventually ruled out, as detectives determined they were motivated by avoiding gun charges.
The Suspects and Trials
Years rolled by, and a new detective revisited the case, casting suspicion back on the original group of teens from 1991, now adults. Through a series of intense interrogations, confessions were extracted from Robert Springsteen, Michael Scott, Maurice Pierce, and Forrest Welborn. The lack of recorded interrogations from 1991 left room for doubt about the validity of these confessions, as it was unclear if detectives had inadvertently supplied the suspects with incriminating details.
The prosecution's case leaned heavily on these confessions, leading to the convictions of Springsteen and Scott. Springsteen faced a death sentence, while Scott was sentenced to life imprisonment due to his age at the time of the crime. However, the prosecution's strategy of using each defendant's confession against the other was deemed a violation of the Confrontation Clause, resulting in their convictions being overturned in 2009. Meanwhile, DNA evidence revealed that none of the implicated men matched the DNA found at the scene, prompting the abandonment of retrial plans.
The Quest for Justice
The specter of coercion loomed over the case, particularly involving Detective Hector Polanco, who had faced accusations of extracting false confessions in another notorious case. This cast further doubt on the legitimacy of the confessions obtained in the yogurt shop case. As the years passed, seven jurors publicly stated they would not have convicted Scott and Springsteen had they known about the DNA evidence earlier.
At the time of the murders, known serial killer Kenneth McDuff was in the area, but he was soon ruled out as a suspect, and he was executed in 1998 for other crimes. Over the years, more than 50 individuals confessed to the yogurt shop murders, including McDuff on the day of his execution, but all confessions proved false.
In 2006, the Texas Court of Criminal Appeals overturned Springsteen's conviction, and the U.S. Supreme Court upheld this decision. By 2008, defense lawyers requested further DNA testing, which eventually led to the release of both Springsteen and Scott on bond in 2009. The charges against them were dismissed later that year, citing the lack of conclusive evidence.
The Ongoing Investigation
The case continued to haunt investigators. On December 23, 2010, Maurice Pierce, one of the original suspects, was shot and killed by police during a confrontation following a routine traffic stop. Despite the passage of time, efforts to solve the case persisted. In December 2021, legislation was passed allowing families to petition the federal government to reexamine cold cases. By February 2022, advancements in DNA technology brought investigators closer than ever to identifying the perpetrators. In August 2022, President Joe Biden signed The Homicide Victims' Families' Rights Act, designed to ensure federal law enforcement reviews cold case files with modern technology.
Cultural Impact
The haunting nature of the yogurt shop murders has left a lasting mark on popular culture. Beverly Lowry's nonfiction book "Who Killed These Girls? Cold Case: The Yogurt Shop Murders," Corey Mitchell's "Murdered Innocents," and Scott Blackwood's novel "See How Small" all delve into the heart-wrenching story. In 2025, HBO released a four-part documentary exploring the case, keeping the conversation alive.
