Gangland info missing with vanished jail chief David Prideaux MISSING jail boss David Prideaux had copies of statements made by gangland serial killer Carl Williams and his father, George, including sensational allegations of police involvement in corruption and murder, when he disappeared in Victoria's high country during a hunting trip in June 2011. It is understood that police have been unable to locate the explosive statements, contained on a CD-ROM, since Mr Prideaux's disappearance. The Australian has learned that during the eight-day search for Mr Prideaux, a work colleague found sensitive files in his four-wheel-drive vehicle parked at the remote Tomahawk Hut, on the Buckland Spur Track in the Alpine National Park, where he was last seen.
