The Tennessee Bureau of Investigation is investigating an allegation of sexual misconduct against a Grundy County corrections officer.
Grundy County Sheriff Clint Shrum confirmed his agency is working with the TBI and the 12th Judicial District Attorney's Office investigating claims that employee Mark Nunley had inappropriate sexual contact with a female inmate or inmates, according to a Grundy County Sherrif's Office news release.
Nunley has not been charged, but was terminated Wednesday for reasons indirectly related to this incident. Nunley was the supervisor over the inmate litter crew and assigned to the corrections division.
"At the request of 12th District Attorney General Michael Taylor, TBI Agents are investigating an allegation of official misconduct against an employee of the Grundy County Sheriff's Department," a TBI spokesperson said.
"This administration will not tolerate this type of conduct. The security of our female inmates is a priority and we have taken steps to ensure that. While this accusation is very disturbing, it does not define every employee of the Sheriff's Office. We will continue to work with both the TBI and District Attorney's Office to find answers," Shrum said.
