Garrett Cooper, 46, of Tulsa, Oklahoma, was found dead from gunshot wounds behind a business at 6744 South Lewis Avenue on Sunday afternoon, March 19, 2023. Officers later determined the shooting occurred about 7 p.m. on March 15, leaving his body undiscovered for several days in a partly hidden area of the commercial strip near 71st and Lewis.

Investigators focused on people in Cooper’s personal circle. Police identified 42-year-old Steven Lee Gillis as the person who confronted Cooper at 6744 South Lewis and later acknowledged to officers that he had shot Cooper. Authorities also located Ashley Abel and brought her in; she was reported to be arrested on an accessory charge and, along with Gillis, was charged in connection with the killing. Police said no additional suspects were being sought at that time.

Is anyone in the Tulsa area familiar with Cooper, Gillis, or Abel and the dynamics described between them?
