PLUM, Pa.—Three houses at the center of a recent explosion near Pittsburgh that killed six people will need to be torn down and 10 others are not currently inhabitable, county officials said over the weekend.
The Aug. 12 blast in Plum leveled one home and engulfed two neighboring houses in flames. The 10 uninhabitable homes will need to be inspected by structural engineers for next steps, an Allegheny County spokesperson said.
