Gill Woolmer, wife of Pakistan cricket coach Bob Woolmer who died in Jamaica on Sunday, said on Thursday she had not ruled out the possibility that her husband had been murdered.
Jamaican police said on Tuesday that the 58-year-old's death was being treated as "suspicious".
Former England batsman Woolmer was found unconscious in his Kingston hotel room less than 24 hours after Pakistan's shock World Cup defeat by Ireland which knocked them out of the tournament. He was pronounced dead in hospital later that day.
"I suppose there is always the possibility, I mean some of the cricket fraternity fans are extremely volatile and passionate about the game and about what happens in the game... so I suppose there is always the possibility that it could be that (murder)," she said in an interview with Sky Sports.
"It fills me with horror. I just can't believe that people would behave like that or that anyone would want to harm someone who has done such a great service to international cricket."
She said that he was "depressed" at Pakistan's defeat but ruled out suicide, adding that he was fit and had been trying to lose weight because of diabetes.
"He was very depressed and he sent me an email to that effect, but he always got depressed and down when the boys didn't do as he expected and hoped," she said.
"But that was normal in any competition, he was a very competitive person. But there's no way that suicide was involved, he would never ever..."
She said that she was waiting for the results of a second pathologist's report before her husband's body could be flown home to South Africa.
"They have given me some indication of why they think it's suspicious but I'm not prepared to say what," she added.
Conspiracy theories have abounded since Woolmer's death, with claims in some media that he had been murdered by a match-fixing syndicate.
Pakistan won their final rain-affected match on Wednesday when they beat Zimbabwe by 93 runs.
