A man was charged with fatally stabbing his ex-girlfriend and her roommate inside their Manhattan apartment on Tuesday morning, police and sources said.

The victims, Jaslynn Pena, 37, and Belky Cruz, 51, were found inside the Fort George apartment at about 10 a.m. after a neighbor spotted blood outside of their door and called police, according to police and sources.

Pena and Cruz were both stabbed in the chest and neck, sources said.

They were taken to the Harlem Hospital and pronounced dead, cops said.

Their alleged attack, Kelvin Valdez, who used to be in relationship with Pena, was seen fleeing the apartment.

Police caught up to the suspect, who had a cut to his hand, about a block away from the scene, sources said.

Later Tuesday, Valdez was charged with two counts each of murder and criminal possession of a weapon, according to police.
