Mario Guerrero, 26, was shot in the head outside his home at 1898 Belmont Avenue in the Bronx's East Tremont just after 5 p.m. on Thursday, September 5, 2024. He was pronounced dead at the scene. His family says he was a quiet guy who worked construction and kept to himself.

Police are looking for a man with a dark complexion, about 5'10", with braided hair, dressed all in black and carrying a black book bag. He ran north on Belmont Avenue.

That was broad daylight on a busy block, and there may be camera footage. If you recognize that description, NYPD Crime Stoppers is 1-800-577-TIPS.
