Investigators Sift Through Wreckage After Explosion

BRISTOL, Pa. (AP) — Crews are using construction equipment to clear the rubble of a Pennsylvania nursing home after a powerful explosion killed two people and hospitalized 20 others. The blast happened Tuesday at the Bristol Health & Rehab Center, northeast of Philadelphia. Bristol Police Chief Charles Winik said Wednesday that searchers accounted for everyone who had been thought to be missing. Authorities say a utility crew was responding to reports of a gas odor when the explosion occurred. Investigators are examining whether a gas leak caused the blast. Emergency responders evacuated residents amid flames, a strong gas odor and a second explosion. On Wednesday, workers were clearing sections of collapsed roof and walls to help investigators gain better access.
