Yeah The Demeo Crew killed a few informants as did Casso and Amuso.Another one that Casso and Amuso took out was the GArbage guys Kubecka and Barstow.The Bompenseiro hit reminds of another outfit informant that was killed.Seifert the guy Lombardo and possibly Spilotro took out.He was killed at his workplace I believe in front of his family
