Evidence 'sound' in Cranks case

A series of checks was made to ensure that there were no discrepancies in the DNA analysis of samples taken from the remains of suspected murder victim Betty Ketani.

This was the testimony of Ana Bilic, a quality assurance and quality control manager at the International Commission for Missing Persons, in Bosnia, in the trial of three men accused of murdering Ketani, a chef at the defunct Cranks Thai restaurant in Johannesburg.

Carrington Laughton, and brothers David and Carel Ranger, are on trial in the Johannesburg High Court for the murder of Ketani, who was last seen in May 1999.

Thirteen years later, six bones believed to be hers were discovered in a shallow grave. Three of the bones were sent to Bosnia for analysis and three were analysed in South Africa.

Bilic took the court through the analytical procedure. She said there were no discrepancies in the analysis and the reference samples had not been contaminated.
