A teen was found dead on the roof of a Brooklyn housing development and cops said Wednesday he was the victim of a homicide.

Cops were patrolling the Brevoort Houses on Bainbridge Street near Ralph Avenue around 4:20 p.m. Tuesday when they discovered 18-year-old Ihuoma Uchanma’s body on the roof.

EMS workers pronounced him dead at the scene.

Uchanma, who lived on Ralph Avenue around the corner from the building, was reported missing the day before, police said.

It wasn’t immediately clear how he was killed or how he ended up on the roof.
