David Campbell, aged 77, was convicted of the shotgun murder of his former colleague Brian Low in February 2024. The incident took place on a secluded track near Aberfeldy, Perthshire, where Campbell, described as an expert shot, executed a premeditated attack on Low, aged 65. The circumstances surrounding the murder were chilling, with Campbell having disabled his home CCTV and used duct tape to obscure his doorbell camera to mask his activities before the crime.

During the trial, Prosecutor Greg Farrell portrayed Campbell's actions as a "brazen, brutal and planned execution" and highlighted the calculated measures taken by Campbell to evade capture. After the shooting, Campbell fled the scene on his wife's e-bike, showcasing a trail of further deception and planning. The shotgun used in the crime was disposed of and remains missing, contributing to the premeditated nature of the attack as Campbell attempted to eliminate evidence against him.

The conviction of Campbell not only brings justice to the family of Brian Low but also raises questions about workplace dynamics and the extreme consequences that can arise from professional disputes. This case serves as a grim reminder of the potential for violence within seemingly ordinary settings and emphasizes the importance of addressing conflicts in healthy, non-violent ways. The long-term implications of this case may lead to discussions about community safety and the resources available for conflict resolution among colleagues.
