Police want to question McAfee about Gregory Paull, who was found lying in a pool of blood at his home, CNN reported Monday.
Paull, a 52-year-old U.S. citizen, was found dead by a housekeeper during the weekend at his home on the Caribbean island of Ambergris Caye. Police said he had been shot in the back of the head.
Reports differ on when the body was found. Raphael Martinez, a national police spokesman, said Paull, who lived alone, was found Saturday morning. A police website said Paull was found about 8 a.m. Sunday and had last been seen alive about 10 p.m. Saturday.
The whereabouts of McAfee, who left his firm in 1994, are unknown.
He told the website for Wired magazine he had been hiding from Belizean authorities for several months and knew "nothing" about Paull's death "other than I heard he had been shot."
