Last year a very good biography on Manson came out, and it was very well researched and went in depth about his time in prison, and there was no mention of him befriending any mafia guys in prison, not to stay it couldn't have happened though. He did spend the vast majority of his life in prison, even before he got life. The book is "The Life and Times of Charles Manson." I'm not really evem into the Manson stuff, but found the book great, it dispelled a lot of misinfo accepted as truth over the years.
