Fifteen-year-old Mohamed Hussein was shot fatally on September 19, 2023, in Pittsburgh’s Allentown neighborhood. First responders found him about 10:45 a.m. on the 700 block of Excelsior Street with a gunshot wound to the torso; he was taken to a hospital in critical condition and later died.

Witnesses reported a suspect fleeing down Excelsior toward Allen Street, leading detectives to detain two people at an Allen Street residence. Investigators later arrested 17-year-old Diontae Carter; he was taken into custody without incident and charged as an adult with criminal homicide, robbery, carrying a firearm without a license, and possession of a firearm by a minor. Carter is being held in the Allegheny County Jail.

Police say Hussein had been present at a prior Braddock shooting on August 27, 2023, that killed two 17-year-olds, Nazir Parker and Rimel Williamson. Video evidence recovered from another teen’s phone and body camera footage reportedly placed Hussein near that scene and showed him handling firearms; one gun was later recovered at the Braddock scene. Authorities have not disclosed a definitive motive or confirmed a direct link between the Braddock incident and Hussein’s killing.

If anyone saw Hussein that morning on Excelsior Street or has information about possible connections to the earlier Braddock shooting, please come forward.
