A posting on John McAfee's blog has claimed the anti-virus software pioneer, wanted by police over his neighbour's murder, appears to have been found after weeks in hiding.
The website set up by Mr McAfee after he went on the run said there was an unconfirmed report that he was apprehended on the Belize-Mexico border.
The website whoismcafee.com has carried updates of Mr McAfee's progress since the murder of Gregory Faull, a 52-year-old retired American builder, on November 11. He has also taken to Twitter to promote his posts.
Under the title Breaking: John captured? a post, on December 1, said: "We have received an unconfirmed report that John McAfee has been captured at the border of Belize and Mexico.
"More information as it is received."
But a subsequent posting on the blog, by a person claiming to be close to Mr McAfee, said there was no confirmation that he had been found.
Mr McAfee has written entries describing how he has disguised himself as a beggar, a street trader and a drunken German tourist in order to watch police as they searched his Belize home.
At one point he claimed he was actually hiding out on his compound on the island of Ambergris Caye.
He said he set up the website to counter claims made about him by the media and the Belize authorities and to assert his innocence shortly after his disappearance.
In an early post Mr McAfee said that he had given enough information to a friend to keep the website going should he be captured.
Police have said they simply want to question Mr McAfee over the murder of Mr Faull, who was found dead in a pool of blood at his home. He had suffered a single gunshot wound to the head.
Mr McAfee has denied he was responsible for the murder and says he went into hiding only because the Belize authorities have a vendetta against him. He believes he was the intended victim of the shooting, not Mr Faull.
Mr McAfee amassed a \$100m (£63m) fortune from his software business but said he lost all but \$4m of it in the financial crisis. He moved to Belize in 2008.
