Episode Overview
When 36-year-old programmer Lisa Valdez doesn't arrive at work, her apartment manager discovers her gruesomely murdered in her small studio. Her body is covered in stab wounds, and the walls are splattered with blood. The crime scene reveals that the killer took her long, dark hair as a grisly trophy. Detectives wonder if a serial killer is on the loose or if Lisa was killed by someone she knew. While clues on her answering machine point to a co-worker with unreciprocated feelings for her, two bloody fingerprints found on a toilet seat exonerate him, leaving the case unsolved for over a decade. The investigation reignites when a detective finds a match in the state’s DNA database, unearthing a surprising connection from Lisa's past.
