Detectives probing the unsolved murder of Nairn banker Alistair Wilson have noted more than 150 new statements in the last year.
Next month marks 17 years since Alistair was gunned down on his own doorstep.
No one has ever been arrested for the crime.
No motive for the murder of the father-of-two has ever been established.
Last October, Alistair’s son Andrew – who was just four at the time of the shooting – appealed for help in the hunt to find the killer.
He revealed the only memory he has of his father is the image of him lying on the family doorstep, covered in blood.
‘This crime has left a family devastated’
Figures obtained through a Freedom of Information request revealed that 164 new statements have been noted since Andrew’s public appeal.
Detective Superintendent Graeme Mackie said: “The investigation into the murder of Alistair Wilson is active and we continue to investigate any new information we receive.
“It cannot be stressed often enough that this crime has left a family devastated and Police Scotland is committed to finding the answers for them and bringing the offender to justice.”
What happened to Alistair Wilson?
On November 28, 2004, Nairn made headlines around the world.
30-year-old Alistair was reading his two young sons a bedtime story when his killer rang the doorbell of his three-storey sandstone house.
It was around 7pm and the family were going through their usual Sunday night routine.
Alistair’s wife Veronica answered the front door to a man wearing a baseball cap who uttered only: “Alistair Wilson.”
A few minutes later, the bank manager was fatally shot – with three rounds being fired.
Nairn will be forever linked with the mysterious case
Sandy Park was Nairn’s Provost at the time of Alistair’s murder and remains hopeful that somebody can be brought to justice.
Sandy had met Alistair just a few months before his death at a business dinner in the town’s Newton Hotel.
He said: “When I’m out somewhere, people say ‘oh you come from Nairn that’s where the murder was’.
“I’m pleased to hear Andrew’s appeal has created that amount of statements.
“It might be something that he should think about doing again.
“It will just need something to open a door and it is such a mystery that there hasn’t been anyone brought to justice.
“I will never forget it. This time of year it always comes up in conversation in my circle of friends.
I would welcome any help from members of the public and hopefully the appeal continues to jog people’s memories.”
