A homeless man has pleaded not guilty to charges he set off a homemade bomb near a Southern California synagogue.
Sixty-year-old Ron Hirsch entered pleas Monday in Los Angeles federal court to four felonies involving use of an explosive and a destructive device. He faces up to 70 years in federal prison if convicted.
Hirsch is accused of setting off an April explosion that caused a 250-pound steel pipe partially encased in concrete to crash through the roof of a home next to the Chabad (hah-BAHD) House synagogue in Santa Monica.
Some debris went through the ceiling of a bedroom where a 12-year-old girl was sleeping but nobody was hurt.
Hirsch was later tracked to Cleveland and arrested.
He also faces state charges that carry a potential life sentence.
