In a new development, a group of Scotland Yard investigators has concluded that Pakistan coach Bob Woolmer died of a heart attack even as the Englishman's friends still suspect that his killers may have sent his last email.
A pathology report submitted by the Scotland Yard team said that the Pakistan coach died of natural causes, and not manual strangulation as was initially reported by Jamaica's deputy commissioner of police Mark Shields, media reported.
The Scotland Yard report specifically said that the 58-year-old Woolmer died of heart failure, contradicting earlier reports by the investigative arm of the Jamaica Constabulary Force (JCF) and a local pathologist Ere Sheshiah, who had conducted post-mortem on Woolmers's body.
According to the Scotland Yard, there was no evidence to suggest that Woolmer was murdered, a case that the JCF is yet to prove conclusively.
Meanwhile, according to a report by The Sunday Telegraph, the Jamaican police are "very interested" in the email, which is suspected to be Woolmer's resignation letter to Pakistan Cricket Board (PCB) chairman Nasim Ashraf.
Woolmer's friends suspect that his murderers might have sent it, as the language in the mail was not familiar to what the late coach used.
In a part of the e-mail, Woolmer is supposed to have written: "I would like to praise my association with the Pakistan team but now I would like to announce my retirement after the World Cup, to live the rest of my life in Cape Town. I have no lust for the job and I will not like others to make personal remarks at me."
The former Pakistan coach's friends say the wording was clearly not of someone whose first language was English.
"I have received hundreds of emails from him over the years and this is not his style - not the sort of words and phrases that he would use," said South African journalist Neil Manthorp, who is also a close friend of Woolmer.
Former Australian captain Ian Chappell said: "I can't believe it was written by a man whose first language was English."
Woolmer died at the Pegasus hotel in Kingston on March 18, hours after Pakistan had been knocked out of the World Cup.
Shields, heading the investigations into the murder, flew to Cape Town to meet Woolmer's widow Gill about the email.
