An unsolved quadruple homicide took place at an frozen yogurt shop in Austin, on 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 employees of the shop, while Sarah and her friend Amy were in the shop to get a ride home with Jennifer after it closed at 11:00 pm.
Two men stayed late in the shop, although their horrific actions would some come to light, their identities have remained uncertain for more than 30 years.
