On December 30, 1990, 22-year-old Valeri Camille Brooks was working the overnight shift at a convenience store in Versailles, Kentucky. Just after 2 a.m., an alarm was triggered. When police arrived, the store was empty and Valeri was gone.

Hours later, her body was discovered in rural Woodford County. Investigators determined she had been abducted, sexually assaulted, and murdered.

More than three decades later, the case remains unsolved.

In Episode 10 of Buried in the Bluegrass, Greg examines the timeline, the evidence, the unanswered questions, and the five missing hours that may hold the key to identifying Valeri's killer.

Warning: This episode discusses sexual assault, abduction, and homicide.
