|First Appearance||"Catfishing Teacher"|
Nat Phelps is a man who was sexually abused by his teacher Donald Bazinski when he was a teenager. Afterwards, he kept quiet about it for several years. However, after Bazinski kidnapped and molested another student, Nat went to Bazinski's home and tortured him to death.
He videotaped the assault and brought the footage to the Special Victims Unit, confessing that he did it so Bazinski could no longer abuse his students. He was arrested for murder and imprisoned. (SVU: "Catfishing Teacher")
