According to Albert DeMeo - he said that that last Christmas (meaning Dec 1982) his father spent pretty much the entire day locked in his study, Roy wasnt in the festive mood because he knew his days were numbered, he even walked around outside with a 12 gauge in his coat in the final days of his life.

As to the feds giving him a deal! giving Gravano one was bad enough but could they ever give a deal to a guy who had dismembered bodies and chucked them over Fountain Avenue dump?
If the feds had 26 murders to charge the DeMeo crew with you can bet your bottom dollar that the real number was alot higher!
