PLUM BOROUGH (KDKA) - Saturday was not the first time Plum Borough experienced a home explosion.
Just last year, in April, a home on Hialeah Drive was leveled and in 2008, less than a half-mile away, another home exploded on Mardi Gras Drive.
An investigation from the National Transportation Safety Board found that the 2008 explosion was caused by a two-inch gas line that had been hit years before.
