On the night of November 3, 2011, 26-year-old Keandre Ellis was shot dead in an upstairs apartment at 1006 South Saint Louis Avenue in midtown Tulsa. Neighbors heard a commotion and gunfire shortly before midnight; officers who entered the unit found Keandre mortally wounded by a chest wound and pronounced him dead at the scene. His younger brother, 22-year-old Timothy McDowell, was critically injured with multiple gunshot wounds and taken into surgery. A third resident told police she awoke to a fight, then a gunshot.

Early investigators were unsure whether shots were fired from inside or from outside the apartment, but told reporters they believed the victims knew the person responsible rather than it being random. Police and news reports identified 56-year-old Richard Mayne as someone who had been at the residence earlier that evening; he left on foot before officers arrived and was publicly sought in the immediate aftermath.

Anyone with information about that night, the apartment at 1006 South Saint Louis Avenue, or Richard Mayne’s whereabouts is asked to come forward.
