In the late 1982 the situation for Roy DeMeo was getting worse with the Feds that was trying to nail him and his boss that was finding someone who would have the ball to whack him.
But if Roy would decide to run away from NY and get on the lam in a place like the Indiana or the Idaho? In 1982 there was no Facebook, instagram or internet so would be hard for LE and mobsters to find Roy.
My second question is:Gotti in 1986 would re-admit Roy in the family?
And third:what proofs had the feds on him? Could go to trial also in 1986?

Any high level gangster from that era served long prison sentences or were killed. He’d be on year 35 of a 500 year sentence.

Why 500 years sentence? And your isn't an answer.

Dominick would have got him convicted. His murders normally had multiple witnesses. One person would eventually flip and convict him. He did way too much to walk free.

DiNome,Montiglio and Vito Arena was the demeo crew members that flipped but I don't think that could nail Roy for life.

Would have been on the run for awhile. And eventuality stand trial and get time. Hypothetical what ifs are impossible to answer. Maybe a few guys wouldnt have turned rat

He had the connections and the money. He was an international stolen car dealer. He could have gotten away long before he was killed. Just like Salvie Testa, he thought he'd be able to take whatever came at him.

He would have run out of money and if he had people sending him money the cash would be traced. I don't see him as the sort to last long on the run. I just can't picture him settling down and hanging around peacefully or blending in.

He’s dead and his scumbag friends killed him.
That’s the only way they could get him, the sneaky way.

They would not have sent him a bag of shit.

JG would not even sit in the same room with him.

The car ring was known to be his and a few Murders were already on his lap.

He completely over exposed himself.

Enrico Ponzo was on the lam from 1995 to 2011 in Idaho as cattle rancher,so I think that Roy could be able to find a job and live as a simple John Doe.

I have to disagree, I just do not see him dealing with a regular life. Imagine him in an argument or dispute with a neighbor. It is possible, but he would have to undergo a drastic change in personality.
