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 Paul, 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 Paul was a well-liked builder who hailed originally from California. The two men had been at odds for some time. Last Wednesday, Paul 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.

Evidently, McAfee’s behavior has been extremely erratic, probably due in no small part to his experimentation with psychoactive drugs. McAfee had posted extensively on a Russian drug message board about his quest to purify psychoactive drugs, such as “bath salts,” and about testing the products on himself (including using a technique known as “plugging,” or rectal insertion). During the past several months, he spent time in the Belizean jungle attempting to synthesize drugs from native plants as well as associating with known drug gangsters.

Twitterers aren’t quite sure what to make of the news:

Just another manic Monday.
