A former detective who believes he has found the motive for the murder of Nairn banker Alistair Wilson flew into the Highlands yesterday.
Peter Bleksley, who spent 21 years with the Metropolitan Police, believes he has discovered a motive for the murder, and will spend the next few days interviewing “interesting sources” to gather evidence to hopefully prove his theory.
And he claimed the investigation had significantly “moved forward” in the last few days.
Mr Bleksley is refusing to reveal what he believes to be the motive behind the 13-year-old mystery.
But just hours after landing at Inverness Airport yesterday afternoon, he told the Press and Journal: “I have obviously got a number of interesting sources to interview.
“In recent days I have been contacted by phone, text, e-mail and social media with information.
“I think I have discovered potentially a very credible motive for the murder, but I need to put some flesh on the bones, broaden it out and research it more thoroughly.”
Father-of-two Mr Wilson was a business manager with the Bank of Scotland when he was murdered on the doorstep of his home at the age of 30.
He was shot three times on November 28, 2004, by the killer, who had arrived at the family home just as he was getting his children ready for bed.
Mr Wilson was handed an envelope by the murderer, went inside to speak to his wife Veronica, before returning to the door, where he was shot.
Police have been unable to determine a motive for the killing and have no suspects.
A gun, which has been confirmed as the murder weapon, was discovered several days later in a drain.
Mr Bleksley said he has lined up interviews with a number of sources. He has had no response from Mrs Wilson or Police Scotland.
He will be in Nairn until Sunday and intends to carry out door-to-door inquiries while also posting leaflets through letter boxes.
He said: “I will be going to places of interest, revisiting the scene, meeting and talking to people. I have a lot of work to do.”
The ex-detective, who helped set up Scotland Yard’s undercover SO10 unit, is revisiting Mr Wilson’s killing for a new book looking at Britain’s most baffling unsolved murders.
