Authorities arrested the wife of a former South-Doyle High School assistant football coach on Thursday after a grand jury met and charged her with six counts of statutory rape and one count of exploiting a minor.

According to the presentment, Kelsey McCarter had multiple sexual encounters with the young man between February and December in 2015, who was listed on the football team's roster.

The documents said McCarter was in a "position of trust" with the boy and used that position to create the sexual relationship.

Kelsey McCarter’s arrest follows an “extensive investigation and collaborative effort” between the Child Abuse Unit of the Knox County District Attorney General’s Office and the Family Crisis Unit of the Knox County Sheriff’s Office, prosecutors said.

McCarter’s bond was set at $30,000. She was released on bond early Friday morning.

She is married to Justin McCarter, who resigned in February after citing a “career change.”

The DA’s Office also “reviewed the actions” of Justin McCarter, principal Tim Berry and assistant principal/athletic director/head football coach Clark Duncan, focusing on “their conduct in the aftermath of the allegations concerning” Kelsey McCarter.

Berry and Duncan were placed on paid administrative leave in February, pending an investigation into allegations they didn’t perform their “essential responsibilities and duties,” according to records.

Prosecutor said they looked into the trio since “this conduct related to state law requiring the immediate reporting of child sexual abuse to DCS of law enforcement officers.”

District Attorney General Charme Allen said “after a careful review of the evidence in this case” she was not going to pursue criminal charges against them.”

Berry, a former principal in Loudon County, has been with KCS since July 2011 and earned a salary of almost $103,000. Duncan has been with the school system since 1981 and earned $86,640.

McCarter, who resigned Feb. 4, joined KCS in 2008 and earned $15,400.

SDHS assistant principal Sherry Smith is acting principal.
