Alberto R. Walter Tavares was 16 when he was fatally shot in Brockton, Massachusetts, in the early morning hours of September 14, 2018. A Brockton High School student and motocross enthusiast who liked to dance, Alberto was the front-seat passenger in a vehicle driven by his older brother when a bullet tore through the front passenger seat and struck him.

According to investigators, the shot originated from the back seat where two passengers had been sitting, one identified as Tony Semedo-Cardoso, who was reportedly handling a firearm behind the driver. After the gun discharged at about 1:12 a.m. near the James Edgar playground, the two back-seat occupants fled. Alberto was taken to Signature Healthcare Brockton Hospital but was pronounced dead at 2:05 a.m.

Brockton Police and State Police detectives investigated the case and an arrest warrant was issued for Tony Semedo-Cardoso. He was taken into custody and initially arraigned on a murder charge; a Plymouth County grand jury later returned an indictment on manslaughter and unlawful possession of a firearm charges.

Does anyone have information about Alberto, the vehicle’s occupants that night, or events near the James Edgar playground on September 14, 2018?
