BRENTWOOD, Pa. (AP) — Authorities have identified a man found dead after a house fire in a borough near Pittsburgh caused by an apparent explosion.

The Allegheny County medical examiner's office said 56-year-old Michael Festa died in the 12:30 p.m. Thursday blaze in Brentwood.

Matt Brown, chief of the county's emergency services, said Festa was found in an area between the house and the garage. He said it was unclear whether the victim made it out of the home or was thrown from the building by the blast.

The cause of the explosion and fire remains under investigation, but Brown said he didn't think it was a gas explosion.
