Brian Ackerman was a white supremacist whose group was investigated in the shooting of three schoolchildren, one of which died. He had a son named Kyle, who was killed by FBI Agent Dana Lewis during the boy's shooting rampage at his father's trial, which claimed the lives of a court officer, Judge T. Schuyler, and Brannon Lee Redding. Ackerman later claimed that he was proud that his son died a "hero". (SVU: "Raw")
Five years later, Ackerman sent Seth Coleman to rape Lewis to get revenge for her killing his son. (SVU: "Penetration") He is currently serving a life sentence without parole in Attica for murder in the first degree and conspiracy to commit terrorism in the first degree.
