"American billionaire tycoon John McAfee, known for creating antivirus software, has been found dead in his Catalan prison cell, as confirmed by prison sources. The inmate’s death comes a day after the Supreme Court approved his extradition to the United States for alleged tax crimes committed between 2016 and 2018.
The well-known computer scientist was arrested in October last year at Spain’s El Prat airport and has been in the Sant Esteve Sesrovires jail (Barcelona) since where a search and arrest warrant from the United States was placed on him."
