2. A Man And A Bike

Having already heard about David Campbell’s temper, todays episode moves on to the relationship between him and the victim, Brian Low. The court hears that they were colleagues, who didn’t always see eye-to-eye.

And we hear evidence about an incident, more than a decade earlier, which might have cemented ill feeling between them.

Later in court – attention turns to an incident in 2023, just three months before the murder. A man is seen riding a bike, close to the location where Brian would later be killed. Some witnesses think he’s carrying a gun. And their evidence leads to a possible identification. Is this an early clue, or a red herring which might confuse the jury?

Inside Murder Trial is hosted by Jane MacSorley, with expert analysis from Tommy Ross KC. The series is a Firecrest Films production for BBC Scotland.
