CHELMSFORD, Mass. (AP) - Fire tore through a northeastern Massachusetts condominium building, killing a couple in their late 60s or early 70s and injuring four of their relatives, including a 7-year-old boy who suffered serious burns, the state's fire marshal said Sunday.
The fire in Chelmsford began at about 11 p.m. Saturday. State Fire Marshal Stephen said he believes the fire started accidentally in the couple's home on the top floor of the four-story building, one of several in the complex.
The victims' names haven't been released. Coan said the man who died used a wheelchair, which impeded efforts to get him out of the condo.
Fire officials said two adults and two children related to the couple were visiting them when the fire began. The boy was flown by helicopter to a Boston hospital to be treated for serious burns, while the others were taken to local hospitals. His condition wasn't available Sunday.
Firefighters rescued several other residents of the top floor from their balconies.
Coan said the cause of the fire was being investigated.
It was the third fatal fire in Massachusetts since Friday.
Accidental fires killed a 70-year-old man in Winchendon on Friday evening and a 15-year-old girl in Holyoke on Saturday, officials said.
