In February, the recently retired 65-year-old Brian Low was found dead on a remote trail close to Aberfeldy, Perthshire.
After 30 police worked to solve the case, the force—which has been accused of a bungled investigation—admitted that, two months after the cold-blooded execution, it still has no suspect and no motive.
The Police Investigations & Review Commissioner (Pirc), Scotland’s police watchdog, is investigating the first seven-day delay in announcing a murder investigation.
Martin Gallagher, a former superintendent who left the force in 2022, said there are issues with the officers who found Mr. Low’s body and prepared the case.
