DOWNTOWN BROOKLYN — A 44-year-old man who was found with a severe head wound in a Brooklyn treatment residence died early Sunday, police said.
David Barron was found at 6:27 a.m. by cops responding to a 911 call of an assault inside a Nevins Street housing facility run by the Institute for Community Living, according to police and workers.
The man was rushed to Long Island College Hospital, where he was later pronounced dead on arrival, cops said.
Leonardo Martinez, 32, who also lived at the SRO, was detained at the scene and later charged with murdering Barron, police said.
The eight-story building, called Stepping Stone, serves as a residential and supportive single-resident occupancy and treatment facility for adults battling mental illnesses and drug addictions, according to organization websites and residents who spoke to DNAinfo.com New York.

Several residents said they heard it started with a fight, and that the incident occurred near the victim's fifth floor apartment.
Workers at the building refused to comment on the attack, but a spokesman for the organization said the ICL was working with authorities.
"We are saddened by this loss and we support the work of the investigators and we will help them in any way we can," said Ron Gold, a spokesman for ICL.
