John Smith was last seen near a golf course by a neighbour.
He was described by police as a 'vulnerable man'.
Searches were made by the police, air support, mountain rescue, the RNLI and the RAF but no trace of him has ever been found.
It was noted that he needed to take certain medicine each day and it was not known whether he had had any on him when he had gone missing.
