LOWELL, Mass., July 15 (UPI) -- Investigators say that a fire that killed seven people in a Lowell, Mass., apartment building started accidentally from an electrical problem.
At a news conference Tuesday, State Fire Marshal Steve Coan said the blaze began in a crawl space between the wood-frame building's second and third floors. He said the fire spread undetected in that area and exploded when it burned through the floor, getting a new source of oxygen.
