Authorities in Texas hope an unexploded bomb will provide clues in the hunt for a killer. A U.S. congressman from Texas is confirming that a suspicious package found at a FedEx facility in Austin contain a bomb. Representative Lloyd Doggett told the "Austin American-Statesmen" federal officials believed the suspect or suspects used the same FedEx store to send at least two parcel bombs. Four bombs have gone off in the Austin city limits this month, killing two people and injuring four others.
