Volume IX of the HSCA's Appendices contains reports on organized crime. While the HSCA report was equivocal on the source of the JFK conspiracy, Chief Counsel Blakey went on to co-write a book which charged that Kennedy was killed by organized crime. Much of the analysis relates to Jack Ruby, whose organized crime connections were analyzed in great depth compared with the Warren Commission, which avoided Ruby's mob connections. The organized-crime link to Oswald is much weaker, consisting largely of his uncle's connection to the Marcello crime family.
