Thursday morning, police continued to look for more possible suspects in and around the building.
The victim was shot in the seventh-floor hallway of the Saint Mary's Houses on Westchester Avenue just after 8:30 p.m. Wednesday.
He apparently got into a fight with at least four other men in the hallway when shots were fired, and he was struck in the upper right shoulder. The victim was pronounced dead at Lincoln Hospital.
The motive for the fight and shooting was not immediately known, but money was found on the hallway floor, and detectives are investigating if the dispute started as a robbery.
Hours after the murder, police specialized units descended on the apartment building and burst into multiple apartments.
Seven persons of interest were taken into custody and a gun was recovered.
Those in custody are being questioned, and no charges were immediately filed.
The name of the victim has not yet been released.
