A dispute at a July 12, 2024 barbecue in the Albany Houses courtyard in Crown Heights turned fatal when 21-year-old Dyseem Jackson was shot and killed just after midnight. Reports say the confrontation began after Jackson intervened when another man inappropriately touched a woman. Police got a 911 call for an assault at 1400 Bergen Street at 12:18 a.m.; officers found Jackson with multiple gunshot wounds to his head and he was pronounced dead at the scene. Evidence markers and shell casings were found both in the building lobby and on the sidewalk, and a firearm was recovered.

A few hours after the shooting authorities arrested 37-year-old Usamah Sidberry, a fellow Albany Houses resident, and charged him with murder and two counts of criminal possession of a weapon. Sidberry pleaded not guilty at his arraignment in Kings County Supreme Court; the hearing erupted into a physical altercation between the families, and Sidberry’s sister was taken into custody after throwing her phone and a bag at Jackson’s mother. Sidberry’s next court date was set for September 6.

If anyone witnessed the confrontation in the lobby or on the sidewalk that night, or has information about what happened before the shooting, please come forward.
