Kelli Ann Cox was 20 and a University of North Texas criminal justice student when she disappeared on July 15, 1997. She had driven to Denton that day for a class visit to the local police department, parked across from the station and accidentally locked herself out of the car. Around noon she called her boyfriend to help get into the vehicle; by the time he arrived, her car was still in the lot but Kelli was gone. She failed to pick up her child that evening, and her mother reported her missing to Denton police.

Extensive searches and investigations did not locate Kelli at the time. Her remains were found in 2016; decomposition prevented a definitive cause of death. Investigators later linked the case to William Lewis Reece. In June 2022 Reece pleaded guilty to Kelli’s murder along with other Texas killings and received life sentences.

What details about Kelli’s movements in Denton on July 15, 1997, or anyone who saw her near the police station that day might help clarify what happened?
