Two of the victims were standing in the third floor hallway of 350 E. 124th St. about 1 a.m. when bullets started flying, striking both men in the back, police said.
The third victim was walking up the stairway between the third and fourth floors when he was shot in the right his and right shoulder.
All of the wounded were expected to survive their injuries, according to authorities.
It is unclear what caused the shooting. Third floor residents of the building where the shooting happened declined to talk about the incident Monday morning.
One man said he was not in the building when it happened. A woman who declined to open her door to a reporter said she didn't know anything about it.
The shooting comes two weeks after Holder's death and one month after the death of Lamont Mason, who was also shot at the Wagner Houses.
No arrests have been made, police said.
