John McAfee Death and Cause of Death
John McAfee was found dead in his prison cell in Barcelona, Spain, on June 23, 2021, while awaiting extradition to the United States on tax evasion charges. The official cause of death was reported as suicide by hanging by Spanish authorities and the Catalan regional government. He was 75 years old at the time of death and was being held at the Brians 1 prison near Barcelona after a Spanish court approved his extradition order earlier that month. Forbes reported the immediate details of his death.
Before his death, McAfee had repeatedly denied the tax evasion charges and claimed he was being politically targeted by U.S. authorities. His legal team filed multiple appeals against extradition, arguing that his health conditions and the risk of harsh treatment in U.S. custody made extradition dangerous. Spanish courts ultimately rejected those appeals, and the decision to extradite him was finalized just days before his death in custody. U.S. Department of Justice documents outline the tax fraud charges against him.
John McAfee Net Worth, Companies, and Financial Legacy
McAfee Antivirus and Early Business Career
John McAfee founded McAfee Associates in 1987 and built one of the earliest commercial antivirus software companies, which was later acquired by Intel in 2010 for an estimated sum that contributed to his personal wealth. He served as CEO of the company until 2014, when he left amid disputes over the company's direction and his public statements. The company evolved into Intel Security and later became part of Trellix, a cybersecurity firm that continues to operate independently today. Forbes covered his business trajectory and net worth.
Crypto Projects and Regulatory Scrutiny
In his later years, McAfee promoted various cryptocurrency projects, including his own token, and became a vocal advocate for decentralized finance and privacy-focused digital currencies. The U.S. Securities and Exchange Commission charged him in 2020 with failing to register securities offerings and promoting crypto assets without disclosing payments he received. SEC enforcement documents detail the crypto-related charges. His death in a Spanish prison interrupted further legal proceedings and left several ongoing regulatory and civil matters unresolved.
John McAfee Death Timeline and Extradition Process
McAfee fled the United States in 2019 after the IRS charged him with tax evasion for failing to file returns for multiple years. He traveled through several countries, including Guatemala, where he was detained in 2020 on an Interpol red notice and later deported back to the United States. Spanish authorities arrested him upon arrival in Spain in October 2020, and Spanish courts spent months reviewing extradition requests from U.S. prosecutors. DOJ press releases track the timeline of charges and extradition.
