Dr. Langley started his law enforcement career more than 30 years ago in Custer County working as an office deputy. He quickly rose through the ranks there, and hired on with the OSBI as a Special
Agent in 1977 assigned to the Lawton office. Only three years later, Langley was promoted to Deputy Inspector in Woodward. He was the lead investigator within that region and supervised the only long term "sting operation" in the history of the agency. Dr. Langley became Inspector in that region four years later.
In 1990, he was promoted to Deputy Director of OSBI. Five years later, the Commission appointed him as Director. Langley has spear headed the implementation of many revolutionary crime fighting tools including the first statewide criminal intelligence unit and the first Association of Crime Laboratory Directors (ASCLD) accredited laboratories in the state. Under his Administration, the OSBI became the first state level law enforcement agency to become accredited through the Commission on Accreditation of Law Enforcement Agencies (CALEA). Director Langley holds a Bachelor of Science Degree in Law Enforcement from Northwestern Oklahoma State University, a Masters of Science Degree in Natural and Applied Science, and a Doctorate of Education in Applied Educational Studies from Oklahoma State University.
