KINGSTON, Jamaica (CNN) -- A pathology report indicated that Pakistani cricket coach Bob Woolmer died of "manual strangulation," according to a statement from Jamaican police commissioner Julius Thomas.
"We are now treating this as a case of murder," the statement said.
Police announced Tuesday that Woolmer's death was suspicious, two days after he was found unconscious in his hotel room. Woolmer, 58, was declared dead at a hospital soon after he was found.
Initial media reports indicated he died of a heart attack.
The tragedy came less than 24 hours after his team were beaten by underdogs Ireland in one of the biggest shocks in World Cup cricket history.
Earlier Thursday, it was revealed that Pakistani players were being interviewed and fingerprinted by police who are probing Woolmer's mysterious death.
Players whose rooms were on the same hotel floor as Woolmer will submit statements as part of the ongoing investigation, a team spokesman told CNN.
"It is standard procedure," spokesman Pervez Mir said. "Each of them will come along and give a written statement."
"The interviews are taking up to an hour for each player," added Pakistan team manager Talat Ali.
"The impression being created by the media is that the team are being interviewed as suspects. That is not the case. They are being interviewed as others are."
The team will then leave Kingston later in the day and head to Montego Bay, Jamaica, for two days' rest before returning to Pakistan, Mir added.
Former England Test cricketer Woolmer, 58, died shortly after being found unconscious in his Kingston hotel room on Sunday night.
Jamaican police said on Tuesday night that his death was "suspicious" leading to a string of conspiracy theories.
Speaking to Sky News from her home in South Africa, Gill Woolmer said she did not believe her husband had committed suicide.
"It is suggested there might be foul play and they (the Jamaican police) don't want to jump to any conclusion.
"I suppose there is always the possibility as some of the cricket fraternity fans are extremely volatile and passionate about the game."
"That fills me with horror, I can't believe that anyone would behave like that towards someone who had given such great service to international cricket," she said.
