Antivirus software pioneer John McAfee dead after hanging himself in jail

Antivirus software tycoon John McAfee apparently hanged himself in a Spanish jail cell on Wednesday — just hours after a court ruled he would be extradited to face federal charges in the US.

Authorities said a preliminary investigation determined there were no signs of foul play, the Spanish newspaper El Pais reported.

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 newspaper reported McAfee was pulled from his cell in Barcelona and police are investigating the circumstances around his death.
