Jamaican police investigating the killing of Pakistan's coach at the Cricket World Cup have received results of toxicology tests but released no information about the findings.
"We have received the toxicology report but we're not going to go public with it right now," Deputy Police Commissioner Mark Shields told reporters at the Kingston hotel where coach Bob Woolmer's body was found the day after his team was eliminated from the World Cup.
Shields, a former Scotland Yard detective who is heading the homicide probe, said the results would "require further analysis and investigation" in coming days.
British detectives conducting a review of the investigation have delivered their findings to police, but Shields did not disclose details of that report either.
Woolmer's death March 18 shocked the global cricket fraternity and cast a pall over the Cricket World Cup, being played in nine Caribbean countries through late April.
The 58-year-old Englishman was found unconscious in his hotel room and pronounced dead at a hospital the morning after his squad was upset by Ireland on St. Patrick's Day.
A pathologist who conducted Woolmer's autopsy initially ruled his death "inconclusive" but four days later announced he had been strangled.
Shields has said Woolmer likely knew his killer or killers because there was no sign of forced entry at his hotel room. More than three weeks later, investigators have not identified any suspects.
A coroner's inquest into the killing begins in Kingston on April 23.
