What I don't get is: If Daniel Marino sent his nephew James Hydell to kill Casso in '86, why would Marino then reach out to Casso and the Lukes during the same time period to kill Gotti in the bomb that killed Frank DeCicco?

Marino never sent hydell to kill gaspipe....angelo ruggiero did. Casso called angelo a idiot and a blabbermouth. Angelo got pissed and ordered paradiso to kill casso and paradiso sent hydell

That's completely crazy. Angelo was a soldier in the Gambinos and Casso was a captain in the Lukes and became underboss around this time. I wonder why the hell Angelo thought he could get away with that?

actually angelo was a captain. Angelo took over gottis old crew after paul was killed an gotti took over in december 85. The whole hydell/casso thing took place in september—october 1986

But are you sure Casso was underboss already, when they tried to whack him? I thought that, with all those legal proceedings during the Commission trial, Tony Ducks's 100 year sentence was definitely upheld in 1987 only, so before that, Amuso and Casso weren't official boss and underboss yet? Although I often get specific dates confused, so can't be sure.

If they let Furnari out, Casso will eventually see the outside world.
They probably are waiting for an illness to hit, and then he will be given a release.

Casso's next-door neighbor, Philip Carlo, wrote a book about him that had a lot of Casso's own claims in it. Casso says the government took all of his information and then fed it to Sammy Gravano, but that they were suppressing Casso's information on numerous other murders and drug deals that Sammy had never confessed to (and would obviously destroy his credibility on the stand). And that the Feds wanted Gotti and would do anything they could to get him.

He also says he was offered a five-year deal but the FBI never honored it, and he had nothing in writing.

Read that book This is true..
