British daily Sunday Times today quoted sources close to the Jamaica police as saying that high concentrations of a herbicide were discovered in the murdered Pakistan cricket coach’s stomach and traces were found on the inside and outside of a glass from which he had been drinking champagne.

“Everything was contaminated. The stomach content, the glass, everything. There was enough to kill him,” a source said.

The weedkiller is so rare that the police have yet to establish whether it is available in Jamaica and they are focusing on two bottles of champagne gifted to him. One had been emptied and the other was left untouched.

“We think it’s something very unusual, that you can’t even buy in Jamaica. We don’t know what form it was in, whether liquid or crystal.

“The weedkiller was certainly in the glass. We aren’tsure whether it was in the bottle. Until we get further results we can’t confirm it,” the source added. It is not known whether he shared the bottle of champagne with another person.

Pervez Mir, who was the spokesman of the Pakistan cricket team for the World Cup, confirmed Woolmer had received the champagne.

“I was told that somebody has brought two bottles,” he said but added that the coach was not particularly fond of champagne.

One expert from Guy’s hospital poisons unit in London said such compounds were usually ingested accidentally or by people committing suicide.

“The use of a herbicide in homicide is pretty rare if not totally exclusive to this case,” the expert said.
