Mail Bomb Kills Man, Injures Wife in Colorado

A man was killed and his wife was hospitalized in serious condition Monday after a mail bomb exploded in their driveway, hurling fragments nearly two blocks away.

Investigators searched for clues to the origin of the bomb, which had been mailed last Tuesday in Colorado Springs and picked up at a post office on Saturday.

Police did not release the names of the victims. The woman, who has head injuries and a broken arm, is in the Army, stationed at Ft. Carson. Her husband was a former soldier.
