I think I now know the answer after reading award-winning investigative journalist & author Matt Birkbeck's new book, "The Quiet Don; The Untold Story of Mafia Kingpin Russell Bufalino. Secretive-even reclusive-Rosario "Russell" Bufalino quietly built his organized crime empire in the decades between Prohibition & the Carter presidency. His reach extended far beyond the coal country of Scranton, Pennsylvania, & quaint Amish farms near Lancaster. Bufalino had a hand in global, national, & local politics of the largest American cities, many of its major industries, & controlled the powerful Teamsters Union. His influence also reached the highest levels of Pennsylvania government & halls of Congress, & his legacy left a culture of corruption that continues to this day. "The Quiet Don" is one of best crimes books I've ever read & I read a ton of them. To what extent WAS the bullying Bufalino involved in the disappearance of Jimmy Hoffa back in 1975? Check out this uniquely American saga that spans 6 decades. "The Quiet Don" follows Russell Bufalino's remarkably quiet ascent from Sicilian immigrant to mob soldier to a man described by a U.S. Senate subcommittee in 1964 as "one of the most ruthless & powerful leaders of the Mafia in the United States.

The man's also on twitter but don't ask me how to get there from here...I'm still trying to figure out e-mail!  Nicholas Pileggi, author of "Wiseguy" & the screenplays for "Goodfellas" & "Casino" writes, "The Quiet Don" is a triumph. Matt Birkbeck provides a stunning work of investigative journalism that is memorable & alive & unveils the incredible life & legacy of one of the mobs most important power brokers". As for what really happened to Hoffa, this doesn't surprise me. I had more or less suspected this all along!
