This is the public’s first look inside the nerve-centre of the new inquiry into the shooting of Nairn banker Alistair Wilson.
The team of 30 detectives assigned to the case this week have begun the painstaking work of re-examining the thousands of statements taken during the nine-year investigation into the circumstances of the 30-year-old’s death in Nairn.
The public are being urged to respond to the plea for help to solve the puzzling case.
Mr Wilson was shot on the doorstep of his home in Crescent Road on November 28, 2004.
Minutes earlier, his wife, Veronica, had opened the door to a stranger who asked for her husband.
He had just put his sons, Andrew, then four, and two-year-old Graham, to bed.
Mr Wilson spoke to the man before returning inside, carrying an A4 envelope, to speak to his wife.
When he went back to the front door, he was shot several times. Mr Wilson, who had been a business manager with Halifax Bank of Scotland in the Highland capital, was due to start a new job with Building Research Establishment, a consultancy business expanding in the north of Scotland.
The inquiry team has now established its base at Burnett Road Police Station, Inverness.
Detectives from around Scotland have been drafted in to help the new investigation.
Attention is focused on the gun used in the shooting.
It was a Haener Suhl Model 1 Schmeisser’s Patent pistol made more than 60 years ago.
It was found 10 days after the murder when a Highland Council road-sweeper dredged it up from a drain a few streets away from the Wilsons’ home.
The .25-calibre ammunition used in the killing originated in the Czech Republic.
At the time of the original inquiry, officers travelled to mainland Europe to trace the history of the weapon.
New forensic tests are being carried out on the pistol but results are not expected to be available for some weeks.
Mrs Wilson, who was 33 at the time, was able to provide a description of his killer.
The man was between 35 and 40 and of stocky build. He was clean-shaven, wearing a baseball hat and a blouson jacket and was last seen heading towards the seafront.
Crimestoppers has offered a £5,000 reward for information leading to the arrest and conviction of the killer.
Anyone with information about the shooting should contact police on 101 or Crimestoppers on 0800 555111.
