Geraldo: Texas Bomber 'More Like The Joker Than The Unabomber'

FBI Agent Who Helped Catch Unabomber: FedEx Blast a 'Game Changer'

The suspect in a string of bombings in Austin, Texas, was killed in a dramatic confrontation with police overnight Wednesday, authorities said.

The suspect, identified by police early Wednesday as a 24-year old male, was killed near a Round Rock-area motel he was traced to by authorities.

Police said the man fled the motel in a car, drove into a ditch and detonated two package bombs as police closed in, firing at him. It was not immediately clear whether he died from the bombs or shots fired by police. One officer was knocked back by the blasts, but none were seriously hurt.

Austin Mayor Steve Adler expressed his gratitude to the "army of law enforcement" who helped break the case.

"This morning, I expressed on behalf of an incredibly thankful community the appreciation to the law enforcement agencies and officers that have been here," Adler told Todd Piro on "Fox & Friends."

He said federal officers arrived in Austin "in waves," with more than 500 on the ground and more working on the case remotely from Quantico, Virginia.

"They worked together so well. The sophistication of the equipment that was deployed here, the priority that this was given, not only at the federal level, but the governor and the state level, the local agencies, the surrounding community, [Austin Police] Chief [Brian] Manley ... it has been such a team that has worked so seamlessly together," Adler said.

Although the suspect is deceased, authorities have warned that more package bombs could be out there.
