"There's a history of mental health problems with him that the family's been dealing with for a number of years," said Curtis Hill, sheriff of San Benito County, California. Two months ago, John Patrick Bedell's parents filed a missing person report about him, and his mother was concerned he may have purchased a weapon, Hill told CNN. Bedell returned home a week after his parents filed the report, he said. In addition, records show Bedell had run-ins this year with police in California and Nevada. The information came to light as police and FBI investigators looked into Bedell's history. Bedell, 36, "was very well dressed in a suit" and showed "no distress in his appearance" as he approached a screening area to enter Pentagon grounds about 6:40 p.m. Thursday, Pentagon Police Chief Richard S. Keevill said. "He walked very directly to the officers and engaged. He was very well armed. I will tell you that he had two 9 mm semiautomatic weapons and many magazines." The two officers who were shot fired back, as did a third who came to assist, Keevill said. The gunman, identified as Bedell, was shot in the head and arm and died early Friday, authorities said. He wore no body armor, Keevill said. The two wounded officers had superficial injuries and were treated at a hospital and released. Surveillance video shows the gunman acted alone, Keevill said. There is no known connection to domestic or international terrorism, he said. When officers found Bedell's vehicle at a nearby parking garage, they found more ammunition inside, he said. Bedell appears to have railed against the government repeatedly on the Internet. Through podcasts and a Wikipedia page, a man identified online as JPatrickBedell cast the government as a criminal force destroying personal liberties. "This seizure of the United States government by an international criminal conspiracy is a long-established reality," the man said in a podcast in November 2006, which also was published as text online. Such an organization, the man said, "would use its powers to convert military, intelligence, and law enforcement bureacracies (sic) into instruments for political control and the domination and subjection of society, while discrediting, destroying, and murdering honest individuals within those services that work to root out corruption and faithfully serve their fellow citizens." The FBI and Pentagon Police, in a joint news release, said Bedell was from Hollister, California. Court records from California show that investigators arrested a John Patrick Bedell in June 2006 on charges of cultivating marijuana and resisting arrest. That John Patrick Bedell had the same birth date authorities give for the Pentagon shooter. In an Internet posting, JPatrickBedell referred to being arrested in 2006 on marijuana charges. "Given my belief that cannabis prohibition is the least defensible and most unjust aspect of the prohibitionist regime existing throughout the world today, I decided in March 2006 to cultivate cannabis in full view of the world," the person said in a 2006 podcast. In a video posted on YouTube in October 2006, a man identified as jpbedell talked about his idea for "information currency," which he said would "create a financial market for information." The man in the video is the same man shown in a photograph of the shooter released Friday by the FBI. The man's voice in the YouTube video also sounds similar to the voice in the podcasts. A person using the screen name JPatrickBedell wrote about the same idea on a Wikipedia page that was taken down early Friday. At a news conference Friday morning, Keevill, the Pentagon police chief, said Pentagon and Metro cameras of the area show the gunman in the time leading up to the shooting. He showed "no real emotion in his face" as he approached the officers Thursday evening, Keevill said. When asked for identification to enter the Pentagon, authorities said, he pulled a gun from his pocket and fired. Officers Jeffrey Amos and Marvin Carraway returned fire with semiautomatic weapons, Pentagon spokesman Terry Sutherland said. The officers suffered nonthreatening injuries -- one in the thigh and the other in the shoulder, Keevill said. They were placed on administrative leave, which is routine in officer-involved shootings. Investigators closed the Pentagon subway station Friday, affecting the commutes of thousands of Washington-area residents. Subway trains were instructed to bypass the Pentagon, transit officials said. "It's a complicated crime scene. There were a lot of bullets fired," Keevill said. He applauded the officers for ensuring that the gunman did not set foot in the nation's defense headquarters, where about 23,000 military and civilian employees work. The officers took less than a minute to neutralize him, the chief said, adding that their action saved lives. He said it was not immediately clear which officers' shots hit the gunman. "The Fort Hood incident put us on notice that this can happen anywhere," he said, referring to the Texas Army post shooting in November that left 13 people dead. The FBI, which is helping investigate, is checking "everywhere" the man has ever visited, Keevill said. Authorities do not know what the man's motive may have been, he said. It also was not immediately clear if he said something before opening fire, the police chief added. "Investigators are searching the car, conducting interviews and reviewing a video of the shooting in an effort to piece together a timeline of Bedell's activities leading up the incident," the FBI said in a news release.
