An East Ridge police officer was recently fired for having a sexual relationship with an 18-year-old high school student, despite an internal affairs investigation that determined he had not violated any department policies or criminal laws.

Acting City Manager Kenny Custer fired officer Adam Rose on Nov. 21, saying Rose's conduct was "contrary to the community standards of honesty, justice and/or good moral values," according to his notice of termination.

On Oct. 25, East Ridge High School Principal Tammy Helton contacted the police department after a teacher learned about a student having a relationship with a police officer, according to internal affairs records. The next day Rose, 29, was placed on administrative leave with pay and an internal affairs investigation began.
