The horrific 1991 “Yogurt Shop Murders” in Texas remained one of America’s most disturbing unsolved crimes for more than three decades. The brutal killings of four teenage girls shocked the city of Austin and destroyed the lives of many families connected to the case. Now, after 34 years of unanswered questions, investigators say DNA evidence has finally identified the killer — a deceased serial rapist named Robert Brashers.
What Happened in the Yogurt Shop Murders?
On the night of Dec. 6, 1991, four teenage girls were at an I Can’t Believe It’s Yogurt shop in Austin, Texas.
The victims were:
| Victim | Age |
|---|---|
| Sarah Harbison | 15 |
| Amy Ayers | 13 |
| Jennifer Harbison | 17 |
| Eliza Thomas | 17 |
Sarah and Amy were waiting for Jennifer and Eliza to finish their work shift before heading to a sleepover.
According to investigators, a man entered the yogurt shop while the girls were cleaning up for the night.
Police said the attacker sexually assaulted several of the girls, tied them up, shot them in the head, and then set the store on fire in an attempt to destroy evidence.
The murders horrified the Austin community and became one of Texas’ most infamous cold cases.
DNA Finally Solved the Case After 34 Years
For decades, investigators struggled to identify the killer despite countless tips and multiple investigations.
The breakthrough finally came in 2025 after Austin detectives reopened the case using newer forensic technology.
Dan Jackson, the detective leading the renewed investigation, reexamined old evidence from the crime scene.
A spent shell casing recovered from a drain was later connected to another unsolved murder in Kentucky.
Investigators then used advanced Y-STR DNA testing, which focuses on male DNA markers, to compare evidence across multiple databases.
The DNA eventually matched Robert Brashers, a known serial rapist and suspected serial killer.
Who Was Robert Brashers?
According to investigators, Brashers was 33 years old at the time of the murders.
Police later discovered that he had been stopped by authorities near Las Cruces, New Mexico, just two days after the killings while driving a stolen truck.
Brashers later died by suicide in 1999 during a police standoff before authorities could arrest him in another case.
Investigators now believe he may have committed additional murders before his death.
Amy Ayers’ Final Act Helped Solve the Crime
One of the most emotional moments in the investigation involved DNA found under Amy Ayers’ fingernails.
Detective Jackson said Amy likely fought back during the attack, unknowingly helping preserve the evidence that eventually solved the case decades later.
Officials described her actions as a key reason investigators were finally able to identify the killer.
Wrongful Accusations Destroyed Lives
While the real killer remained unidentified, four young men were wrongly accused of the murders for years.
The original suspects included:
- Michael Scott
- Robert Springsteen
- Forrest Welborn
- Maurice Pierce
Some gave confessions during long interrogations that they later claimed were coerced.
Several were convicted before courts eventually overturned the cases.
In February 2026, a judge formally declared all four men innocent.
Austin Approved $35 Million Settlement
The city of Austin later agreed to a $35 million settlement with the surviving wrongly accused men and the family of Maurice Pierce.
As part of the agreement, the city also banned unsupervised interrogations of underage suspects.
The settlement aimed to address the lasting damage caused by the wrongful accusations and years of public suspicion.
HBO Documentary Revived Attention to the Case
The final developments in the case are featured in the HBO docuseries The Yogurt Shop Murders directed by Margaret Brown.
The documentary explored the emotional toll on the victims’ families, the wrongly accused suspects, and investigators who spent decades searching for answers.
Families Continue Living With the Trauma
Sonora Thomas, who was just 12 years old when her sister was murdered, said finally learning the truth brought both pain and relief.
She also revealed that her mother struggled deeply with the unanswered questions surrounding the case and later died by suicide years before the killer was identified.
For many families involved, the emotional wounds from the murders still remain despite the case finally being solved.
