Antivirus pioneer John McAfee is on the run from murder charges, Belize police say. According to Marco Vidal, head of the national police force's Gang Suppression Unit, McAfee is a prime suspect in the murder of American expatriate Gregory Faull, who was gunned down Saturday night at his home in San Pedro Town on the island of Ambergris Caye. Details remain sketchy so far, but residents say that Faull was a well-liked builder who hailed originally from California. The two men had been at odds for some time. Last Wednesday, Faull filed a formal complaint against McAfee with the mayor's office, asserting that McAfee had fired off guns and exhibited "roguish behavior." Their final disagreement apparently involved dogs.

Police say they simply want to question the 67-year-old about the murder of fellow American Gregory Faull, a Florida native who was found dead at his home last month in a pool of blood on the Caribbean island of Ambergris Caye.

Faull, 52, was shot in the back of the head, according to a police report. There were no signs of a break-in, and a laptop and cell phone were missing.

McAfee has said he fears for his life and was fleeing authorities with whom he has been at odds ever since refusing to make a donation to a local politician’s campaign.

In Belize, a source at the US embassy speaking privately said people close to McAfee, in the town of Carmelita, in the San Pedro area, had denied that he was captured. A police spokesman meanwhile said he had no information on a possible arrest.
