Computer software pioneer John McAfee, who is wanted for questioning in Belize over the murder of a fellow American, arrived in Miami on Wednesday, Dec 12 evening after he was deported by Guatemala, according to fellow passengers on an American Airlines flight, Reuters reported.

After landing, McAfee, 67, was escorted from the plane by airport security officers, passengers said.

Shortly afterward, he tweeted, "I am in South Beach," referring to the popular tourist area on Miami Beach.

McAfee had been held for a week in Guatemala, where he surfaced after evading police in Belize for nearly a month following the killing of American Gregory Faull, his neighbor on the Caribbean island of Ambergris Caye.

Police in Belize want to quiz McAfee as a "person of interest" in Faull's death, although the technology guru's lawyers blocked an attempt by Guatemala to send him back there.

Authorities in Belize say he is not a prime suspect in the investigation. McAfee has denied any role in Faull's killing.

"I'm happy to be going home," McAfee, dressed in a black suit, told reporters shortly before his departure from Guatemala City airport. "I've been running through jungles and rivers and oceans and I think I need to rest for a while. And I've been in jail for seven days."

Guatemala's immigration authorities had been holding McAfee since he was arrested last Wednesday for illegally entering the country with his 20-year-old Belizean girlfriend.
