STEWART, Tenn. -- The bodies of an elderly couple killed in a mobile home explosion in North-Central Tennessee were found in the debris, holding each other.

The blast killed Dorris and Dot Stephenson, 73 and 78-years-old. The couple's daughter said her parents heard a loud explosion late Monday night. Dorris Stephenson ran to the back of the home to get his wife, but neither made it out. Investigators believe a number of oxygen tanks delivered to the home this week were a factor in the blast.
