THE murder of father-of-two Alistair Wilson on the evening of November 28 remains an unsolved mystery.
The 30-year-old banker was shot at his home in Crescent Road, Nairn. No one has ever been arrested or charged with his murder although the police continue to investigate the killing.
Mr Wilson's wife, Veronica, told police a stranger rang the doorbell at 7.45pm and asked to speak to her husband.
Mr Wilson spoke for just a few minutes, closed the door and went upstairs with a turquoise envelope.
He went back downstairs and Mrs Wilson heard a sound like slates being smashed. Her husband had been shot three times.
A massive police inquiry was launched at the time.
The only trace of Mr Wilson's killer was the Haenel Suhl Model 1 Schmeisser's patent handgun which was found down a drain by council workers carrying out gully cleaning two streets away from where the shooting was carried out.
Forensic analysis identified it as the murder weapon but tests on the gun failed to extract any DNA.
