Firefighters worked for about three hours to get the fire under control.
“The house has fireworks in it,” said Derry Township Fire Chief Mark Piantine. “We haven’t found them yet, but the neighbor, who was the first one here, said the fireworks were going off when he came across the yard.”
The fire marshal is working to figure out what sparked the fire and what role, if any, those possible fireworks may have played.
Five people, including children, were able to escape safely.
