On 6 December 1991, a Friday, Jennifer Harbison and Eliza Thomas, both 17, were closing the frozen yoghurt shop where they worked while Jennifer's sister, 15-year-old Sarah Harbison, and 13-year-old Amy Ayers, her friend, waited for a ride from Jennifer. Moments before midnight, a fire at the shop drew first responders, who discovered the four girls had been bound and murdered, with signs of sexual assault.
