John McAfee—the antivirus tycoon whose eccentric, larger-than-life, and often illegal antics on yachts and in tropical rain forests came to define him in later years—took his own life in a Spanish prison cell while awaiting extradition to the US. He was 75.

The death was first reported by El Pais and later by Reuters, both of which cited law enforcement sources in Barcelona. Multiple news agencies also reported the death.

According to El Pais, prison personnel found McAfee hanging in his cell and provided emergency medical services but were unable to save his life.
