He started his FBI career in March 1991 as a special agent focused on criminal enterprise, gangster and illegal drug activities, the bureau said Thursday.
Cox was chosen in August 2009 to help the agency build relationships with international partners under a legal attache program in Copenhagen, Denmark.
Before that role, he held the positions of supervisory special agent, program manager and assistant intelligence branch lead in the FBI Sacramento division.
Cox also operated anti-crime initiatives for the FBI hostage rescue unit based in Quantico, Va. between 1996 and 2002 and later managed international counterterrorism programs at FBI’s headquarters.
Prior to his FBI career, he served as a police department officer in the city of Berea, Ohio.
