"Sopranos": What was Johnny Sack's crime?

At the end of Season 5, Johnny Sack was arrested. But for what crime? I recall one of the government lawyers in a Season 6 episode say they’ve got him for “conspiracy to commit murder.” But whose murder? The Wikipedia article says only:

He was arrested for violation of the RICO (Racketeer Influenced and Corrupt Organization acts. If you remember, he

made a deal with the Feds. He pled guilty to 47 RICO predicates for a reduced sentence of 15 years and a fine of $4.2 million. He also had to enter an allocution that he was part of an organized crime family. He asked Tony to convince his partners, the Calviac brothers to sell their business so he could get his share in order to provide for his wife and Tony had Johnny sell his house for half its value to Janice and Bobby as part of his fee.

But what has any of that to do with “conspiracy to commit murder”? A charge of which the Feds were very confident they could convict him, and neither Johnny nor his lawyer ventured to contradict them.

“conspiracy to commit murder” is probably a pretty easy charge to level at a mobster.

From Wikipedia:“Under RICO, a person or group who commits any two of 35 crimes—27 federal crimes and 8 state crimes—within a 10-year period and, in the opinion of the US Attorney bringing the case, has committed those crimes with similar purpose or results can be charged with racketeering.”

“Commision of murder for hire” is one of the crimes defined in the act and certainly could be what the Feds were talking about.

Only if you can link it to the name of some particular intended victim.

Sure… the guy who turned states evidence against him. Let’s just say he was the intended victim and he knew it… or he was the intended trigger man maybe the intended victim wasn’t family related.
