Michael and Ami Medlin were indicted Monday on three charges each of taking indecent liberties with a student, first degree sexual exploitation of a minor, and sexual servitude.

The charges stem from a criminal investigation of the couple that began in May for possibly having an “inappropriate relationship” with a former student.

On May 17, the SBI was requested by the Johnston County District Attorney to investigate Mike Medlin who had been a school resource officer at Corinth Holders High School along with his wife, Ami Medlin, a teacher at the same school.

Mike Medlin was officially terminated from his position on May 17, CBS 17 previously reported.
