WASHINGTON — The gunman who shot two Pentagon police officers was heavily armed and spent weeks driving to the Capital area from the West Coast, authorities said this morning.

Resentment of the U.S. government and suspicions over the Sept. 11, 2001, terrorist attacks have surfaced in writings by the Californian identified as the man fatally wounded in a hail of return fire.

John Patrick Bedell, 36, of Hollister, Calif., was identified as the shooter, and authorities said he had had previous run-ins with the law.

Investigators have found no immediate connection to terrorism, and the attack at the massive Defense Department headquarters appears to be a case of "a single individual who had issues," Richard Keevill, chief of Pentagon police, said in a news conference early this morning.

Keevill described Bedell as "very well educated" and well-dressed, saying Bedell was wearing a suit, armed with two 9 millimeter semiautomatic weapons and carried "many magazines" of ammunition. There was more ammunition in Bedell's car, which authorities found in a parking garage, Keevill said.

Bedell, 36, died Thursday night from head wounds received in a volley of fire with police. Keevill said the two injured officers and another officer who came to their assistance fired upon Bedell at the subway entrance into the Pentagon building in Arlington, Va.
