Murder Trial: Death of a Dog Walker: BBC Documentary Examines a Disturbing Murder Case
Murder Trial: Death of a Dog Walker is now available to stream on BBC iPlayer, taking viewers inside a disturbing murder investigation that initially appeared to be a tragic case of natural death.

The latest installment of the BBC’s popular Murder Trial true-crime series focuses on the death of Brian Low, a man who was killed while out walking his dog. What initially seemed to be a heart attack soon became something far more sinister, as investigators uncovered evidence that Low had been murdered and that the original police investigation had been badly mishandled.
The case ultimately led to a complicated trial involving disputed evidence, crucial witness testimony and long-standing tensions within the local community.

What is Murder Trial: Death of a Dog Walker about?
The two-part documentary examines the investigation into Brian Low’s death and the subsequent case against his neighbour and former gamekeeper, David Campbell.
Police initially believed Low had died from a heart attack. That conclusion was later overturned when the circumstances surrounding his death were reconsidered and the investigation was found to have been botched.
As the case developed, Campbell faced accusations over Low’s murder. His conduct throughout the legal proceedings was described as shockingly callous, adding another unsettling dimension to an already disturbing case.
The prosecution and defence both relied heavily on witness testimony, while tensions within the community gradually came to the surface. Old grudges and disputes emerged as investigators and prosecutors attempted to establish what had really happened to Low.

A case built from a trail of evidence
The investigation became increasingly complicated as new pieces of evidence came to light.
Deleted CCTV footage emerged late in the investigation, while other recordings from the surrounding area appeared to provide incriminating evidence. Rather than relying on one decisive discovery, the case gradually took shape through a series of smaller details that helped investigators build a more complete picture.
The documentary follows those developments as the evidence is examined and attempted cover-ups are challenged. What initially appeared to be a straightforward investigation into a sudden death eventually became a far more tangled murder case.
