A mother and four children were killed when flames swept through their home in the small Franklin County town of Warwick.
Officials said the fire broke out in the single-family home early Saturday morning.
Warwick Fire Chief Ron Gates became emotional as he said the house was fully engulfed in flames when firefighters arrived, and there was little they could do to prevent the tragedy.
“We’re a very tight bunch, and obviously this is tough on all of us,” Gates said at a Saturday afternoon news conference, according to WWLP.
According to published reports, two other members of the household — a father and child — escaped with minor injuries.
The state fire marshal said the blaze appears to be accidental, and may have originated at a wood stove in the kitchen.
A statement from the Massachusetts Department of Fire Services said the number of fire-related deaths statewide in 2017 is now 18. That includes three victims from a fatal Holyoke fire in January.
Last September, a fire in Greenfield killed four, including a four-year-old boy.
