Brian Ackerman is a white supremacist who was the leader of the Revolutionary Aryan Warriors Neo-Nazi group.
His 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 fellow supremacist Brannon Lee Redding. Ackerman later claimed that he was proud that his son died a "hero". It is revealed that Brian was hired by the dead boy's parents to kill him for the insurance money. (SVU: "Raw")

He is currently serving a life sentence without parole in solitary confinement in Attica for murder in the first degree and conspiracy to commit terrorism in the first degree and as a result of Coleman's conviction, was denied any human contact for life.
