 Authorities say one person is dead and another is missing after a natural gas explosion at a college prep school in Minneapolis. Fire officials say the body was found Wednesday after the explosion caused a partial building collapse at Minnehaha Academy. The school says longtime receptionist Ruth Berg died in the blast and that janitor John Carlson remained unaccounted for Wednesday evening. Now there are media reports within the hour indicating another body has been pulled from the rubble, but there was no confirmation that it was Carlson's body. Contractors were working on the building at the time of the explosion. Authorities say seven adults are hospitalized, including three with critical injuries.
