He also has another property on mainland Belize, a compound of thatched-roof homes near the Mexico border.
One resident of the island told the AP that Faull had complained about McAfee's behavior, and others said the former software executive was hard to befriend.
"His physical appearance doesn't really inspire you to go over and make friends with him. He's a little scruffy looking," said real estate agent, Bob Hamilton.
Police said Faull's computer and phone were missing, but there were no signs of forced entry at his home. Police reported finding a single 9-mm shell casing and said it appeared Faull was killed between late Saturday and Sunday morning, which was a rainy night on the Caribbean island. Faull was last seen at 10 p.m. Saturday.
