The official autopsy on his body John McAfee showed that he committed suicide in his cell in a prison in Catalonia while awaiting extradition to the USA.
The event is reported by El Pais newspaper, citing unnamed sources, who were near the procedure of the autopsy.
The American John McAfee was the creator of the same name software security, and was found by prison officials hanging in his cell last Wednesday. It appeared to be a suicide, his lawyer said last week.
His lawyer, Javier Villalba, said on Friday that McAfee's widow, Janis, had asked for a second, independent autopsy after the results of the first were published.
The businessman was wanted in the US for tax evasion. He was arrested last October at Barcelona airport and taken into custody. A few hours before he was found dead in his cell, the Spanish justice had given the green light for version in the US.
