Another FBI failure.
The FBI had Esteban Santiago in their custody and the FBI let him go.
"In November 2016, Esteban Santiago walked into the Anchorage FBI Field Office to report that his mind was being controlled by a U.S. intelligence agency. During the interview, Santiago appeared agitated and incoherent, and made disjointed statements. Although Santiago stated that he did not wish to harm anyone, as a result of his erratic behavior, interviewing agents contacted local authorities who took custody of Santiago and transported him to a local medical facility for evaluation. The FBI closed its assessment of Santiago after conducting database reviews, interagency checks, and interviews of his family members" FBI Spokesperson
