Dallas Police have arrested an 18-year-old for killing the doorman at an illegal gaming site in the 9200 block of Skillman Street, off LBJ, an event we wrote about last week. According to a police report, Damion Deqail Williams admitted that he attempted to rob the gaming hall with a partner the night Warren Cooksey, 41, was shot in the head. Williams is now in custody at Dallas County jail.
