BRITISH toxicologist Dr John Slaughter was yesterday unable to say conclusively whether the poison cypermethrin was in the body of former Pakistan cricket coach Bob Woolmer.

Slaughter, when asked by the foreman of the jury whether the drug and its by-products would be detectable in urine if a large dose was orally ingested, said he did not know.

“It is possible, but I don’t know.”

Earlier, Slaughter, while being re-examined by Director of Public Prosecutions Kent Pantry, said that testing urine for cypermethrin was not a common practice in England as there was not much scientific literature to support that the insecticide would be found in urine even if large amounts were taken. This, he said, was his reason for not testing the urine sample for the poison.

On Thursday, Slaughter testified that he tested samples of body fluids taken from Woolmer’s body and found that there was no cypermethrin in any of the samples.

This was in contrast with director of the Forensic Sciences Centre in Barbados, Cheryl Corbin’s evidence that cypermethrin was found in the DNA samples taken from Woolmer’s body and sent to her by the local forensic laboratory.

Also giving testimony yesterday, police scenes of crime analyst, Detective Sergeant Devon Harris, said he had taken two drinking glasses and an empty champagne bottle from Woolmer’s room and that tests revealed a fingerprint impression on one of two of the drinking glasses.
