"Deputy State Fire Marshals and ATF agents have concluded their on-scene investigation and turned the scene over to the insurance representatives," officials said Monday. "Crews have already begun cleaning up the copious debris strewn throughout the neighborhood, and restoration companies are beginning to make repairs to nearby homes."

Officials plan to review all evidence collected at the scene, including gas and electrical piping. They said there was no evidence of criminal activity. The National Transportation Safety Board is also looking into the matter.

Authorities ask anyone who smelled gas in the area before the blast to contact them.
