Anti-virus software pioneer John McAfee says he is moving every four hours to avoid police who want to question him about the murder of his neighbour.
Mr McAfee denies killing American Gregory Faull, 52, who was found dead in a pool of blood at his home in the Central American country of Belize on Sunday.
Three people who worked for Mr McAfee, 67, are under interrogation, said Belize police.
Mr McAfee, who has amassed a \$100m (£63m) fortune, told CNBC television he had been "accused of something I didn't do".
He said he was keeping on the move out of fear for his safety, worried that police want to "shake him down" and extort money from him.
A police report said that Mr Faull was shot in the back of the head. It said there were no signs of a break-in, and a laptop and mobile phone were missing.
"We are looking for Mr McAfee to interrogate him," police spokesman Raphael Martinez said, adding he was "not suspected of murder".
Police raided Mr McAfee's mansion on Ambergris Caye, an island off the northeastern coast of Belize, on Sunday to question him about the murder.
Earlier in the year, police searched the property for weapons and drugs, and detained him for several hours.
Mr McAfee claimed afterwards he had been arrested because he refused to make a donation to a local politician's campaign.
He sold his stake in the company that is named after him in the early 1990s and moved to Belize about three years ago to lower his taxes.
He told The New York Times in 2009 that he had lost all but \$4m (£2.5m) of his fortune in the US financial crisis.
