In the early hours of June 2, 2017, 48-year-old Dedric Ellis of Turtle Creek was found critically wounded inside his overturned SUV on McClure Avenue in Pittsburgh’s Marshall-Shadeland neighborhood at about 12:15 a.m. He had multiple gunshot wounds to the trunk and was taken to Allegheny General Hospital, where he was pronounced dead at 1 a.m. The Allegheny County Medical Examiner ruled his death a homicide.

Investigators say Ellis was shot while in his vehicle, which then crashed. Shell casings were recovered several blocks from the crash scene, and a witness reported seeing two cars driving down the street while occupants were shooting at each other before one car, believed to be Ellis’s, crashed and the other fled. Surveillance footage identified a gray Chevy Impala as having followed Ellis’s SUV for about half a mile; the footage allegedly shows the Impala’s driver pull alongside and fire several shots. A witness who viewed the video identified the driver as Melvin Russaw, known as Slug, and later selected him in a photo lineup. Russaw was arrested five days after the shooting and charged in connection with the case.

Did anyone in the area witness the vehicles or the shooting that night or have surveillance footage that wasn’t shared with investigators?
