Martin says he now has that video in possession and he's seeking to attain another video showing the two having sex.
The student's attorney, Warren Martin, says other students at Provine High School reported the two to administrators after they saw the videos posted to social media.
One of the videos reportedly shows the teacher - who has not been named because she has not been charged with any crime - performing oral sex on the teen.
The last time the two had sexual contact was on April 27.
They mostly had sex in the teacher's car, which she used to drop him off at home after tutoring sessions. While the age of consent in Mississippi is 16, it's always illegal for anyone in a position of authority, such as a teacher, to have sex with a minor.
'This teacher saw him, preyed upon him and when she realized he was close to revealing her criminality, she sought efforts to conceal it by offering my client cash payments.'After administrators heard about the allegations, they made a report to the Department of Human Resources and the State Department of Education.
