Multiple large tanks were found in the wreckage of a San Francisco home after an explosion and fire resulted in one death.
Law enforcement officials were spotted shortly before 8 a.m. Friday pulling the tanks and equipment from the home on 22nd Avenue in the Sunset District.
The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) told The Standard it is now assisting the fire department with its investigation into the cause of the blaze.
The blaze—which was contained by 11:25 a.m. Thursday—spread to two other homes on 22nd Avenue between Noriega and Moraga streets, officials said.
One person was seriously burned and a firefighter sustained minor injuries. A third person was found dead in the building after the fire was out, fire officials said.
The fire came after several neighbors reported hearing an explosion at 9:21 a.m. Thursday. SFFD arrived within four minutes, officials said.
