The victim was identified Thursday morning as Ali Flores. Police took at least seven people into custody but were continuing to search for other possible suspects.
Francisco Deleon, 23, was charged with murder in connection to the case, and a 15-year-old boy was also arrested and charged with second-degree murder.
Flores 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. A gun was recovered at the scene.
Flores was pronounced dead at Lincoln Hospital.
Hours after the murder, police specialized units descended on the apartment building and burst into multiple apartments.
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.
The victim's family is now devastated and say they want answers.
"He was a good father and the last time I saw him was February, we had a family reunion and he always says, I love you, and I always said, you know, tell him I loved him," the victim's great-aunt Renee Reed said.
