...David Berkowitz, a.k.a the Son of Sam — the satanic letter-writing serial killer who terrorized NYC and murdered six people in the mid-1970s. [...] Berkowitz is still alive and currently lives at the Sullivan Correctional Facility in Fallsburg, New York; he has positioned himself as a spiritual leader of sorts via his web site, TheSonofHope.com, and has published a book by the same name that includes letters he's written to his followers from prison, who call themselves the Friends of Hope.
