Amid the growing feeling that Bob Woolmer probably died of natural causes, widow of the slain cricket coach insisted her husband was murdered in a Kingston hotel on March 18.
"He was murdered -- but I don't have a clue who would do it," Gill was quoted as saying by The Sun website.
Gill believes in the Jamaican Police version that Woolmer was subdued before he was strangled to death.
"Bob must have been subdued because he was a big man and able to defend himself. But who would do it? The average person would not go to such extremes," Gill said.
Deputy Commissioner of Jamaican Police Mark Shields has been insisting that Woolmer was murdered and said the killer could have been from outside Jamaica.
Shields met Gill and briefed her on the investigation.
Gill also rubbished the notion that her husband was about to blow the whistle on match-fixing.
