Although Bell never attempted to put the assassination market concept into practice, a subscriber to the Cypherpunks mailing list, musician Carl Johnson, developed Dead Lucky, a non-functional mock "assassination bot" which aggregated fictitious contributions and simulated rewards of accurate dead pool predictions. The bot was just a bare implementation of the idea consisting of a web page and email client with no backend to actually use digital cash.  Federal investigators issued a warrant for Johnson's arrest for posting three threatening messages in August 1998.  Johnson was convicted for sending threatening email messages to federal judges and Bill Gates, with prosecutors asking for a seven-year prison sentence...On October 11, 2001, Thomas C. Wales, Assistant U.S. Attorney and a prosecutor in the case, was assassinated, succumbing to multiple gunshot wounds.  The murder remains unsolved.
