They say last November, he walked into the FBI's office in Anchorage, Alaska, claiming that his mind was being controlled by the CIA and that it was forcing him to join ISIS. He appeared agitated and incoherent, and made disjointed statements -- and although he said he didn't wish to hurt anyone, agents were concerned by his erratic behavior and decided to call local authorities, a senior federal law enforcement official said.
Local police took him to a local medical facility for evaulation, and the FBI closed its assessment of Santiago after conducting database reviews, interagency checks and interviews with family members, the official said.
