The DeMeo involvement in child porn is disgusting. Roy DeMeo and his crew in general seem like very sick fucks. I believe they killed a few women and other people who were not involved in the mob. Killing other criminals is one thing, killing some 19 year old girl because she was in the wrong place is really evil.
Tommy Karate Pitera is another one that seems like a sick fuck. He did torture some of his victims before killing. I am not a big Philip Carlo fan, but read the book he wrote about Pitera, the killing of that guy Stern is fucked up.
The Campisis (Genovese associates) in Newark, NJ kidnapped an innocent guy out of a store parking lot, murdered him and buried him in an unmarked grave in a swamp in the early 70s. All because they thought he MIGHT be able to testify against them in a robbery case.(he wasn't testifying) It's in the book Deal by Harvey Aronson.
