Police have been treating the case as murder since shortly after Woolmer's body was discovered in a Kingston hotel on March 18. But the change of tack has come after an investigation by a UK Home Office pathologist who flew to Jamaica to help.
It is claimed the authorities will announce Woolmer died of a heart failure caused by chronic ill health and possibly diabetes at a press conference next week. However, Karl Angell, the Jamaica police's director of communications, told The Gleaner he did not know of any planned news conference for next week.
"Mr Woolmer was not a well man," a source close to the inquiry told the Daily Mail. "It is now accepted that he died of natural causes."
The BBC sports editor Mihir Bose said that Woolmer's widow has heard nothing about her husband dying of natural causes
