John Patrick Bedell had a history of mental illness

The man who opened fire in front of the Pentagon had a history of mental illness and had become so erratic that his parents reached out to local authorities weeks ago with a warning that he was unstable and might have a gun, authorities said Friday.

It's still unclear why John Patrick Bedell opened fire Thursday at the Pentagon entrance, wounding two police officers before he was fatally shot. The two officers were hospitalized briefly with minor injuries.

Bedell was diagnosed as bipolar, or manic depressive, and had been in and out of treatment programs for years. His psychiatrist, J. Michael Nelson, said Bedell tried to self-medicate with marijuana, inadvertently making his symptoms more pronounced.

"Without the stabilizing medication, the symptoms of his disinhibition, agitation and fearfullness complicated the lack of treatment," Nelson said.

His parents reported him missing Jan. 4, a day after a Texas Highway Patrol officer stopped him for speeding in Texarkana. Bedell told the highway patrolman he was heading to the East Coast, and began acting strangely — sitting on his knees by the side of the highway and turning off his cell phone when it would ring.

Bedell said it was his mother calling, prompting the patrolman to answer the phone and talk briefly with her. Family friend Reb Monaco said Kaye Bedell asked the officer to take him to a mental health facility, but that the son refused.
