Upon the conclusion of his temporary placement in the records division of the agency, Aaron was hired and began working full-time as a civilian within the same department. Aspiring to be a police officer, Aaron requested a transfer to corrections in 1998, where he would join the security detachment of the Roger D. Wilson Detention Facility. In the fall of 1999, after fulfilling the requirements of Tennessee Peace Officers Standards and Training (P.O.S.T.) Commission, Aaron became a certified police officer. After shifting from corrections to the front-line in 2000, the following five years on patrol would afford Aaron an opportunity to serve his agency within the capacity of Field Training Officer (FTO)–a voluntary commitment in training new police recruits.
Supervisor of Technology
Captain Aaron Yarnell
Following his promotion to the rank of Sergeant/Detective in 2006, and although spending the majority of his time assigned to the Major Crimes Division of the Sheriff’s Office investigating felonious crimes against persons, Aaron’s investigative expertise is multifaceted and inclusive of comprehensive investigative experience. Correspondingly, Aaron has conducted investigations from those encompassing missing person cases, property crimes, internet offenses, forgery and fraud violations to include both equivocal and unequivocal death investigations. This experience ultimately garnered Aaron a Lieutenant position entrusted with the supervision of a specialized unit focused on the exploration of multifarious incidents, both criminal and civil.
In 2012 unique strategies were implemented within a technologically driven investigative unit guided by customized algorithms and crime analysis; methods deployed to identify, follow, and arrest active career criminals. This division of investigations was initiated behind Aaron’s forward-thinking, a concern circumscribing the exploitation of an accelerating criminal enterprise adjoining computer science. Dedication to this discipline subsequently led to a Captain promotion where Aaron founded an additional division of the Sheriff’s Office, an intelligence bureau named the Special Investigations Unit.
As the current supervisor of the Technology division – a unit consisting of 35 employees, both civilian and certified police officers – Aaron’s responsibilities involve the administration of matters correlating with technology. Such commitment includes the maintenance of equipment involved within the Information and Technology Division; explorations of online deviant activity within the Digital Intelligence Unit; governance of the Organized Retail Theft Crime Division, Digital Communications, Forensic Services Unit, along with Cyber Investigations, Sex Offender Investigations, and Internet Crimes Against Children.
Throughout his career, Aaron has enthusiastically maintained the mentality that teamwork fosters groundwork. Equally, formerly a member of the Knox County Sheriff’s Office Honor Guard and Crisis Negotiation Team, Aaron is honored to contribute to distinguishing operations. Likewise and more recently, Aaron was honored to accept a position offered by the Tennessee Sheriffs’ Association, State Legislative Committee, as lead chair of the Technology Review Board.
Aaron continues to fulfill his love of Technology inside and out of his work voluntarily teaching Social Media Safety to parents he labeled as the S.M.A.R.T initiative, along with maintaining the Knox County Sheriff’s Office needs with Technology support, investigations and forensics.
