Nine-year-old Debbie Randall is abducted while walking home from the laundromat, just yards from her family's apartment.

Sixteen days later, her brutalized body is found dumped eight miles away. Despite law enforcement's best efforts, the seemingly random killer has been unidentified for nearly 50 years. Investigators discover a small rag inside Randall's vaginal cavity and initial testing reveals a partial DNA sample. The sample is sent through CODIS, but no one in the prison system, not even executed prisoners, is a match.

As DNA testing improves, investigators use genetic genealogy to find the killer. William Rose, 24 at the time of the murders, committed suicide just two years after Randall's murder. Randall's brother says he believes the weight of what Rose did to Debbie led Rose to take his own life.
