The victim was identified as Aschton Charles, who had been asleep on the Brooklyn borough home's first floor when the living room fire broke out about 3 a.m., the New York Daily News reported. He was unconscious when firefighters carried him out and was pronounced dead at the scene.
Several other people in the two-story brick home, including his mother, were evacuated. One resident and a firefighter were taken to the hospital with minor injuries, the Daily News said.
The fire was spotted by a neighbor who was out taking photos of the snow and firefighters had the blaze extinguished within a half hour.
A source familiar with the investigation told the Daily News the home had no working heating system and the space heater may have been the only source of warmth for the family of eight. The source said there were no working smoke detectors in the residence.
The landlord, who was at the scene, wept but had comment, the newspaper said.
