[Update Below] One man is dead and another is in critical condition after an incident in the Fulton Houses complex in Chelsea this morning. According to the NYPD, reports of shots fired were called into 911 at 10:53 a.m.. By the time the police arrived on the scene one man was already dead with a gunshot wound to his head—it is currently unclear if the injury was self-inflicted.

The other man at the scene—authorities have not yet released either victim's name or age—was found with a stab wound to the body and has been transported to Bellevue where he is listed in critical condition.

The NYPD has since established a crime scene but no charges have been made as the details of what happened are worked out.

Update: The second man found this morning has also died, according to authorities, and police are now investigating their deaths as a potential murder-suicide. NY1 reports:

Sources say it began when Jamie Cruz and her cousin, Brandon Romero, 20, went to the apartment of Cruz's ex-boyfriend, Kenneth Waldron, 29, to pick up her things.

Sources say Cruz was in a back room when she heard a struggle and a gunshot. Additional shots were later fired and police found Waldron dead in the sixth floor stairwell after apparently shooting himself in the head.

Romero was found in an elevator with gunshot and stab wounds.
