Video shows ex-gamekeeper David Campbell disabling CCTV cameras at his home in an attempt to conceal his whereabouts ahead of murdering his old colleague.
Campbell, 77, killed Brian Low, 65, with a shotgun on 16 February 2024. A jury at the High Court in Glasgow heard that he had harboured a “festering grievance” against Mr Low, who he had worked with at Edradynate Estate.
