Authorities in Spain say that a judge has ordered an autopsy on the remains of John McAfee, the gun-loving antivirus pioneer, cryptocurrency promoter and occasional politician who died in a cell pending extradition to the United States (US) for allegedly evading millions in unpaid taxes.

A court spokeswoman for the Catalonia region said on Thursday that a forensic team would need to perform toxicology tests on McAfee’s body to determine the cause of death and that results could take “days or weeks.” Authorities have said that everything at the scene indicated that the 75-year-old tycoon killed himself.
