Software mogul John McAfee, known for his eponymous anti-virus software, has been found dead in his prison cell near Barcelona, hours after a Spanish court approved his extradition to the United States. He was facing charges of tax evasion and money laundering, as well as of cheating investors in a multi-million-dollar cryptocurrency scheme. Plus, France's highest court has overturned a ruling that shops cannot sell cannabidiol, or CBD, a non-psychotic compound derived from hemp.
