Walter Tompkins is a gay teacher at Manor Hill Academy and serial statutory rapist of the students there. Due to the rape culture existing there that was covered up by Brett Forrester, Tompkins came forward and confessed to his statutory affairs with the boys at the school, fearing he only encouraged what already existed.
He was originally forced by Forrester to take the fall in a lone public apology, but one student came forward and said he consented with Tompkins, who helped him be proud to be gay. However, another teacher and serial rapist, Benjamin Strepek, made passes at the student from wanting to legitimately prey on him. Tompkins testified in court when charges were attempted at the academy, but the judge threw out the case.
Eventually, when more students came forward, including Brett's son Nathan, Brett apologized publicly and admitted the negligence of the sexual abuse on the campus. (SVU: "Lessons Learned")
