(AP Photo/Alan Diaz, File)NEW YORK – Antivirus software entrepreneur John McAfee was indicted on fraud and money laundering conspiracy charges alleging that he and cohorts made over $13 million by fooling investors zealous over the emerging cryptocurrency market, authorities said Friday. McAfee, authorities said, is detained in Spain on separate criminal charges filed by the U.S. Justice Department's tax division. There was still no lawyer listed for him in the Memphis, Tennessee, federal court where tax charges were lodged against him in October. McAfee developed early internet security software and has been sought by authorities in the U.S. and Belize in the past. The Tennessee indictment said McAfee failed to file tax returns from 2014 to 2018, despite receiving “considerable income” from several sources.
