John McAfee's wish to return to the United States appears to have been granted after officials in Guatemala said the eccentric software pioneer would be deported to his home country.

McAfee fled to Guatemala from Belize after being named as a person of interest in the murder of a neighbor and fellow expatriate in Belize, Gregory Faull.

After spending three weeks on the run and slipping across the border into Guatemala, he was detained in Guatemala City where he has been held for the past week on immigration violations.

An immigration official in Guatemala said McAfee was scheduled to leave for the United States on a Wednesday afternoon flight. "Complying with migration law, John McAfee is to be deported to his country of origin," Guatemala immigration office spokesman Fernado Lucero told Reuters.

McAfee said he was booked on a flight to Miami at 3.30pm local time. "That was the only option I had. I can't take a flight that stops in any other country and there are only two flights going to America today."

The US has an extradition treaty with Belize, meaning if the authorities there charges McAfee with an extraditable offense, and requests his extradition, he could be be sent back to the country. As yet, McAfee has not been charged with any crime.

McAfee, who has dual British citizenship, has expressed distrust in the Belize government and claims to have evidence of internal corruption. The government, in turn, has expressed doubts about McAfee's mental stability – the country's president called him "bonkers."

McAfee has posted numerous scribes against the Belize government on the blog whoismcafee.com ,where he and his allies have been posting updates on his situation daily.

On Wednesday, he explained that posts written under the name Harold M had actually been by him and that he had been treated well by Guatemalan authorities.

"The Guatemalans, by the way, have been as nice to me as my own family," McAfee said "The guards and orderlies have been supportive and have treated me with kindness."

On Sunday, he answered questions in the detention center and said he hoped to return to the US which he left in 2008 to retire to Belize.

"I simply would like to live comfortably day by day, fish, swim, enjoy my declining years," McAfee said. "My long-term plan was simply to get away from Belize, think, and decide what to do."

McAfee has been unusually outspoken about his life on the run, contacting reporters by phone, email and in-person since he went into hiding November 11.

This openness seems to have contributed to his eventual arrest in Guatemala after journalists from the fringe-culture magazine Vice, who for a time had been accompanying McAfee, left embedded location data in a photo they posted online.

Though Vice has lost its association with McAfee, Montreal-based production company Impact Future Media announced Monday that it had secured the intellectual property rights to McAfee's life story. The company said it was seeking investors for the project, tentatively titled Running in the Background: The True Story of John McAfee.

McAfee's friend Chad Essley is also represented by the company, which will help with the production and publishing of Essley's graphic novel and animated documentary on McAfee.
