JOHN McAfee's Instagram account posted a mysterious "Q" just minutes after his jail "suicide" death was reported. The antivirus pioneer reportedly killed himself after he was prepared to be extradited to the United States, and within 30 minutes after a news outlet shared the news, McAfee's Instagram uploaded a photo of the capital letter Q. McAfee's latest Instagram post was shared without a caption and showed a black letter "Q" on top of a white background, the Independent reported. The letter "Q" represents a disproven and discredited far-right conspiracy theory, known as QANON, about pedophiles running a worldwide child sex-trafficking ring. Additionally, McAfee once claimed that if he was ever discovered dead by suicide that he did not kill himself.
