LAKESIDE, Calif. (AP) - Authorities say a man suspected of abducting a 16-year-old Southern California girl might be armed with homemade explosives. San Diego County Sheriff's Capt. Duncan Fraser said Thursday that evidence recovered at James Lee DiMaggio's home east of San Diego suggests he might have fled with explosives. The search for Hannah Anderson and her younger brother has reached four Western states, Canada and Mexico. The FBI and various state and local law enforcement agencies are assisting. Fraser says it's possible DiMaggio was infatuated with the girl. Her mother was found dead at DiMaggio's burning home near a dead child who might be the girl's younger brother.
