CLINTON — A Clinton Public Schools teacher reportedly confessed to having sex with a student several times, including during the ongoing teacher walkout, according to the Oklahoma State Bureau of Investigation.

On Saturday, Keri Hoffman, 36, and her husband drove to the Clinton Police Department, where she told law officers that she had sex with the 15-year-old boy several times inside her car in Washita County and inside her father's detached garage in Custer County, according to a news release.

Hoffman also said she had taken a group of students to the walkout at the Capitol last week. Hoffman picked the boy up first and dropped him off last, having sex with him each time, the release states.

Hoffman was charged Monday in Custer County District Court with two counts of second-degree rape, a count of facilitating sexual conduct with a minor by use of technology and a count of pattern of criminal offenses, court records show.
