John McAfee's Instagram account seems to have been taken down after posting an apparent reference to the QAnon conspiracy theory following the cybersecurity software founder's death on Wednesday. 

McAfee, 75, died by suicide in a Barcelona jail on Wednesday after learning that Spain's National Court had approved his extradition to the US to face tax evasion and fraud charges, his lawyer told Reuters. 

Within 30 minutes of English-language news outlets reporting McAfee's death, his Instagram account posted a picture of the letter "Q," the Independent reported.
