LOS ANGELES (AP) — A homeless man has been indicted on charges of planting an explosive that detonated outside a synagogue in Santa Monica last month.

A federal grand jury on Tuesday brought four counts against 60-year-old Ron Hirsch, including use of an explosive to damage property. He could face up to 70 years in prison if found guilty of all charges.
