An FBI forensic DNA expert acknowledged Thursday that none of the blood tested from items linked to the killing of senior Customs official Nigel Christian matched the victim.

The revelation came during cross-examination by defence attorney Wendel Alexander in the murder trial of Saleim Harrigan, Wayne Thomas and Lesean Bully.

Jurors had earlier heard that DNA testing strongly linked Harrigan to gloves recovered in Cassada Gardens and blood-stained overalls from Perry Bay, while Thomas was identified as the main contributor to a shirt found at the same location.

DNA from the Crown’s key witness — who told the court he drove the accused men on the day of the killing — was also detected on clothing recovered during the investigation.

Under questioning, the expert said Christian’s DNA was not identified in the blood samples she was able to test, explaining that several stains were too small or degraded to produce reliable results.

She also confirmed that the only item containing DNA from both Christian and any of the accused was the inside of overalls recovered from Perry Bay, where testing produced relatively low likelihood ratios for both Harrigan and the victim.

Meanwhile, a ski mask recovered during searches that led to the men’s arrest contained no DNA linking any of the accused, a point highlighted by the defence as they challenged aspects of the investigation.

The trial before Justice Rajiv Persaud continues Monday.
