Mr Sandison, (24), was reported missing from Peterhead on Saturday, August 10 following a night out.
Ruairidh was last seen by friends in the Gadle Braes area around 4.20am that Saturday, and despite a massive police search operation including the force helicopter, drones, dogs and searchers, no trace was ever found of the young man.
A spokesman for Police Scotland said: “We can confirm that shortly before midday on Wednesday, September 18, the body of a man was found on the north-east coast at Boddam.
