Charles McElroy, 22, was shot and killed in East Oakland on September 3, 2015. Police responded to reports of gunfire about 4:09 a.m. in the 9800 block of Burr Street and found McElroy with multiple gunshot wounds to the chest. He gave a dying declaration to officers identifying longtime friend Sean Singleton as his attacker, and McElroy died at a hospital at 6:06 a.m. that morning.

Investigators arrested 31-year-old Sean Singleton of Richmond the same day. He was found driving away from his home in the car he and McElroy had used to get to Oakland; officers recovered a loaded pistol in the vehicle and another firearm was seized at Singleton’s residence. Singleton admitted involvement in the shooting and was charged with murder and carrying a loaded firearm in a city; he was held without bail and scheduled to enter a plea on September 15, 2015. The defense asserted self-defense, while prosecutors cited the weapons, Singleton’s admission, and McElroy’s dying declaration as evidence.

Were there witnesses or neighborhood cameras on Burr Street that night who can shed light on what led to the dispute?
