LOS ANGELES (AP) — Federal and local investigators searched through debris, looking for remnants of a possible explosive device, after a blast at a Southern California medical office building that left a woman dead and three other people injured. The explosion occurred around 1 p.m. Tuesday in Aliso Viejo, about 50 miles (80.5 kilometers) south of Los Angeles. It blew siding off the walls, exposing insulation and framing and shattering windows at the two-story building that houses medical offices. "The corner of that building, the whole bottom floor is pretty much blown out," fire Capt. Tony Bommarito said.
