Western Reserve Joint Fire District Chief David Comstock tells 21 News that one woman in her 50s died in a Poland Township blaze Monday morning. 

Two dogs also died in the blaze. 

Dispatch issued an all-call around 6:00 a.m. Monday following an incident that was initially reported as "a house explosion" on Arrel Rd. between Struthers and Woodland Rds. 

Neighbors tell 21 News that they heard a "loud boom" in the early hours. One person, commenting on a post about the incident on Facebook, said the boom was loud enough to wake them up nearly a quarter mile away on Woodland Rd.

The initial call in Poland Township was followed by mutual aid requests to Boardman, Struthers, Youngstown, Springfield, Lowellville, New Middletown, and Beaver, who all responded to the scene according to dispatch.

"Given the fact it came in as an explosion, we have some reason to believe based on that that there may have been gas involved," said Western Reserve Joint Fire District Chief David Comstock.

"We initially shut down the gas to the house itself, and then we asked Dominion to shut it off at the curb and to assist with the investigation," Comstock said.

Police and fire crews remained on scene for more than half the day, and a definite cause of the fire remains under investigation.
