If you were driving on the frontage road near miracle mile Sunday afternoon you may have heard a bomb go off.
Police blew up two pipe bombs found on the west side of I-10 just north of Miracle Mile. A homeless man found them and reported them to police. They don't know who made them or why they were left there. But they say the two devices were sitting next to each other.
