Authorities are looking for a motive for yesterday's shoot-out at the Pentagon.

The Associated Press reports that John Patrick Bedell has been identified as the shooter, and that Bedell had issues with the military and questions about the 9/11 terror attacks.

Bedell was killed after he came out of the subway and opened fire at a Pentagon security booth. He wounded two Pentagon police officers.

Bedell, who is from California, had apparently driven for the last couple of weeks from the West Coast to Washington. After he died, police found ammunition on his person, and in his vehicle which was parked at a local parking garage.
