David Matthew Mazza, known as Matsy, was 46 when he was fatally shot on the night of June 13, 2023, in Clarksburg’s North View neighborhood. Police responded to reports of gunfire near Hamill Avenue, close to the former RESA VII building, and found Mazza with multiple gunshot wounds. He was taken to WVU Medicine United Hospital Center and later died. Court documents state he was shot four times and that parts of the incident were captured on surveillance video.

Investigators used surveillance and license plate reader data to trace a 2015 Nissan Altima to Ulices Alexander Pineda, 43, of Bridgeport. Authorities allege footage shows Pineda chasing and shooting Mazza, then firing additional rounds after Mazza fell. Police say they recovered a .40-caliber Smith & Wesson and ammunition from a safe during a June 16, 2023 search; a round in the gun was reported to match crime-scene evidence. Pineda was arrested and charged with first-degree murder and related firearm offenses and held without bond.

The criminal proceedings did not reach a jury verdict, leaving the case without a conviction. If anyone knew Mazza or has information about the shooting, please come forward.
