Clayton Tierney, 17, was shot in the head and later died after the October 26, 2022 shooting in Pittsburgh’s Beechview neighborhood. He was found about 4:20 p.m. on the 1700 block of Broadway Avenue near the T light-rail tracks, transported to UPMC Presbyterian in critical condition, and pronounced dead at 11:37 p.m. The Allegheny County Medical Examiner’s office confirmed his identity the next morning.

Investigators reviewed surveillance footage showing a verbal argument, a single muffled gunshot from inside the house, and an unknown man in a black hoodie with white text fleeing. The footage also shows that same man raising his arm and firing three shots in the direction of a fleeing person before returning to the house. Pittsburgh police interviewed witnesses and continued gathering evidence.

On December 29, 2022, Pittsburgh police arrested 26-year-old Antwuan Berry in connection with the shooting. Berry, identified as Clayton’s brother, was at the scene and was visibly upset; he was taken to the hospital and later questioned at police headquarters. He was charged with criminal attempt homicide, aggravated assault, persons not to possess a firearm, and firearms not to be carried without a license and was held in the Allegheny County Jail.

If anyone has information about the events on Broadway Avenue that afternoon, please come forward.
