The Yogurt Shop Murders | Marks Unexplained World Podcast (Ep. 156)

The 1991 Austin yogurt shop killings are an unsolved quadruple homicide that took place at an I Can't Believe It's Yogurt! shop in Austin, Texas, United States on Friday, December 6, 1991.

The victims were 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. Jennifer and Eliza were the shop employees, while Sarah and her friend Amy were in the shop to get a ride home with Jennifer after it closed at 11:00 pm.

A Y-chromosome match for the perpetrator DNA has been found in a research database of the Federal Bureau of Investigation (FBI) but it has declined to reveal the identity of the man by the law of anonymity for donors, and because thousands of men could bear this fragment of DNA, which is unable to identify individuals.
