FBI forensic experts told a court that tested blood evidence did not match Nigel Christian. The testimony came during a major murder trial in Antigua and Barbuda.

First, an FBI DNA specialist explained the findings under cross-examination. Defence attorney Wendel Alexander questioned the expert in detail.

The case involves the killing of Christian, a senior customs official. Prosecutors have charged three men with his murder.

Those accused are Saleim Harrigan, Wayne Thomas, and Lesean Bully.

However, the expert confirmed an important detail during testimony.

None of the blood samples tested from several pieces of evidence matched Christian’s DNA.

Nevertheless, investigators did find other DNA links during the investigation.

For example, testing strongly connected Harrigan to gloves recovered in Cassada Gardens.

In addition, investigators found blood-stained overalls in Perry Bay. DNA evidence also tied Harrigan to those overalls.

Meanwhile, scientists identified Thomas as the main contributor of DNA found on a shirt recovered in the same area.

Jurors also heard about DNA connected to a key witness in the case.

This witness told the court he drove the accused men on the day of the killing. Later, investigators detected his DNA on clothing collected during the probe.

However, several samples created problems for forensic testing.

According to the expert, some blood stains were extremely small. Others had degraded over time.

Therefore, scientists could not produce reliable DNA results from those samples.

Still, one item contained DNA linked to both Christian and one of the accused.

Investigators found that mixture on the inside of overalls recovered from Perry Bay.

Even so, the expert explained the DNA match was relatively weak. The likelihood ratios for both Christian and Harrigan remained low.

In addition, another piece of evidence produced no useful DNA results.

Police recovered a ski mask during searches that led to the arrests.

Yet testing found no DNA linking any of the accused men to the mask.

Because of this, the defence highlighted the issue during questioning. Lawyers suggested the evidence leaves unanswered questions about the investigation.

Meanwhile, prosecutors continue presenting their case in court.

The trial is taking place before Justice Rajiv Persaud.

Proceedings will pause briefly before continuing on Monday.

As the trial moves forward, jurors will hear more testimony and examine additional forensic evidence.
