Natural gas identified as cause of deadly explosion that killed 2

Authorities in Gloucester County, New Jersey say natural gas caused an explosion that leveled a home killing two people last week. Investigators say they also found no evidence of foul play.

The Gloucester County Fire Marshal's Office says it was unable to pinpoint the source of the gas leak or say what sparked the blast in Newfield on Saturday. The agency issued its finding Monday, listing the nature of the explosion as "undetermined."

An office spokeswoman said "numerous possible sources of ignition" set off the explosion that killed 73-year-old John Paladino and 72-year-old Carole Paladino at their home on the 300 block of Oakwood Drive.

Neighbors have said the couple had a new stove delivered the day before the explosion occurred. But the office's finding didn't mention the stove in its determination.
