Authorities are investigating a fire that left one man dead at a home in Braintree, Massachusetts late Sunday night.
The fire broke out at a home on Nicholas Road just before 11 p.m. and quickly reached two alarms.
Firefighters responding to the home found heavy smoke coming from the one-floor house.
Fire officials said an older man and his wife who uses a wheelchair were rescued, but their son, 46-year-old Colin Gray Jr., was found dead in a back bedroom where he was likely sleeping when the blaze broke out.
The body was found after firefighters had brought the fire under control.
Neighbors said the family didn't get out much due to health issues.
"That's terrible," said Peggy DelPico, a Meals on Wheels volunteer who arrived Monday morning with food for Gray's parents.
The exact cause of the fire remains under investigation, but fire officials said a space heater is likely to blame. They say there were no working smoke detectors in the home.
