But on Tuesday, Jamaican police said independent pathologists from Britain, South Africa and Canada determined that Woolmer died of natural causes, and closed the murder probe.

The South African pathologist, Lorna J. Martin, said Woolmer's death most likely was related to heart problems, though Jamaican authorities have not disclosed the official cause pending a coroner's report.

"Taking into account his medical history and the findings of the autopsy,
it looks very certainly like it's a cardiac cause of death," said Martin,
who is head of forensic medicine and toxicology at the University of Cape Town.

But Seshaiah told the Observer he is confident the coach was slain.

"Woolmer is not a first for me," he said. "I have been doing autopsies
here since 1995."

An opposition lawmaker called for Seshaiah to be fired.

"He led the investigation team down a wrong path," Derrick Smith said outside parliament.

"Now that we have found out that he has made an error, he should be terminated."
