Explosion and fire kill mom and 6 kids at Pennsylvania home

Authorities say a mother and six children ranging in age from 3 to 11 were killed in an explosion and fire at a central Pennsylvania home.

Pennsylvania State Police say firefighters responding to a report of an explosion and fire at a home in Clinton County on Sunday morning confirmed that seven people were trapped, but they couldn't search the building engulfed in flames.

All seven died.

Police identified them as 34-year-old Sarah Stolzfus, four sons and two daughters.

The cause is under investigation.

Police say a propane leak inside the home may have caused the explosion and fire, however exterior propane tanks did not explode and were not contributing factors.
