Antivirus software tycoon John McAfee apparently hanged himself in a Spanish jail cell on Wednesday.
The 75-year-old eccentric tech entrepreneur was arrested in October and was awaiting extradition in the Barcelona jail when he was found dead by hanging, police sources told El Pais.
The Spanish High Court had agreed to extradite McAfee, who had been charged with a number of federal financial crimes in two districts in the United States.
McAfee was hit with a 10-count indictment in the Western District of Tennessee in October for allegedly evading taxes on millions of dollars in income.
