Authorities say an Amish woman and her six children ranging in age from 3 to 11 were killed in an explosion and fast-moving fire at a rural Pennsylvania home. Pennsylvania State Police say firefighters responding in Clinton County on Sunday morning found that seven people were trapped, but they couldn't search the house engulfed in flames. All seven died. Police identified them as 34-year-old Sarah Stoltzfus, 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. An obituary posted online by a local funeral home identified Stoltzfus as a member of the Old Order Amish Church community.
