On a Friday night in December 1991, four teenage girls were closing up a frozen-yogurt shop in Austin, Texas.
Jennifer Harbison was 17. Her little sister Sarah was 15. Their friend Amy Ayers was just 13. Eliza Thomas was 17. They were Future Farmers of America kids who loved animals — Amy wanted to be a veterinarian. None of them made it home.
Sometime before midnight, a man came in. The girls were robbed, attacked, and shot with two different guns. Then the shop was set on fire — not in a panic, but to burn the evidence away. The sprinklers and fire hoses finished the job. By morning, Austin had lost four daughters and almost every clue to who took them.
Then the case went the wrong way
Under long, high-pressure questioning, two young men confessed to the murders. Robert Springsteen was sent to death row. Michael Scott was given life in prison. Two others were accused. Here is the hard part: all four were innocent. Their confessions did not match the crime scene — they matched what a grieving, frightened city wanted to hear.
The families never stopped pushing. For 34 years, they refused to let Austin forget Jennifer, Sarah, Amy, and Eliza.
What finally told the truth
It was not a confession. It was Amy.
She fought her attacker hard enough to leave his skin under her fingernails. That tiny piece of evidence sat in an evidence freezer for decades, waiting for science to catch up. In 2025, three things came together: DNA from Amy's fingernails, genetic genealogy (building family trees from public DNA databases to trace a relative, and then the suspect), and a single spent shell casing found in a floor drain.
They pointed to one man: Robert Eugene Brashers. Investigators say he killed in more than one state. He died in 1999 — which means he was never tried for Austin. He was identified by the evidence, not convicted in a courtroom. But the men who lost years of their lives behind bars were, at last, clearly not the ones who did it.
The same fingernail evidence that named the killer is what set the innocent free.
I spent months rebuilding all of it — the night, the failed investigation, the wrongful convictions, and the science that finally cracked it — in a new book, Before Midnight: The Austin Yogurt Shop Murders. It is coming soon. You are already in the best seat to hear when it lands — you are reading this.
