John McAfee hosted a live video broadcast on his blog from his Guatemalan detention centre, asking to return to the US to lead a "normal life".
In a lengthy video statement, the 67-year-old anti-virus software expert said returning to the US was his "only hope".
The former fugitive said that he had no long-term plans during hiding and "simply would like to live comfortably day by day, fish, swim, enjoy my declining years."
He denied murdering his neighbour Gregory Faull in Belize and said there was no hope for his life if ever returned to the country, claiming it is corrupt.
