The documents claim that the teacher and student started exchanging naked pictures and obscene films before having two physical interactions.
According to the lawsuit, the youngster allegedly went to the classroom Hancock was instructing during her lunch break.
The teacher is accused of grabbing the adolescent during at least one meeting as they shared a kiss inside the classroom closets.
Superintendent Mike Franz informed the newspaper that the abuse was brought to the attention of the school district in November.
Hancock was swiftly kicked out of the school and reported to the Police.
According to some residents of Wellston, Hancock is the wife of Chief of Police Alfred Hancock and the daughter of Mayor Paul E. Whitnah.
Because of the conflict of interest, the Oklahoma State Bureau of Investigation is handling the case, according to Lincoln County Sheriff Charlie Dougherty.
