Bowe Bergdahl, a former missing U.S. prisoner of war who is facing charges of desertion, was a surprise guest at a drug raid Tuesday morning at a marijuana farm in Northern California. Bergdahl was visiting a friend in Mendocino Country when the police force arrived. He was not arrested or connected with the farming of drugs. Mendocino County Sheriff Tom Allman told The Daily Beast that Bergdahl told him he knew the target of the raid, who had 181 plants, for 10 years. “He was very polite,” Allman said. “He was very clear that he had not smoked marijuana.” According to a spokesman at Fort Houston, Bergdahl was on authorized leave when the raid happened. “He did not do anything wrong,” the spokesman told The Daily Beast. “He was not the target of the sheriff’s investigation.” Bergdahl has since returned to the military base.
