On the evening of March 14, 2018, 22-year-old Collis Walker was found shot to death in the driver’s seat of an SUV in a parking lot at 12241 N. Pennsylvania Ave in northwest Oklahoma City. The initial call of shots fired came around 8 p.m.; when officers arrived Walker, originally from Dallas and a senior studying industrial safety at the University of Central Oklahoma, was deceased. He had been a former defensive lineman for the university’s football team and was months away from graduating.

A friend who had been with Walker reportedly ran into a nearby liquor store and asked a clerk to call 911; store security footage later showed that person hiding in an aisle after seeking help. The Oklahoma City Police Department classified the death as a homicide and said in the days afterward that they had no new leads. No arrests or suspect identifications have been publicly announced and the investigation remains open.

If anyone has information about collisions, activity, or people in the parking lot at 12241 N. Pennsylvania Ave that night, please share what is known with investigators.
