Police Scotland make fresh Alistair Wilson murder appeal

On November 28 2004 Alistair Wilson spent the perfect Sunday rambling along the blustery Scottish coast with his wife Veronica before returning home for dinner and to tuck his two young boys into bed.

Hours later a strange man came to the door asking to speak to the 30-year-old banker.

The events that unfolded in the following few minutes would see Mr Wilson brutally gunned down on his doorstep - shot twice in the head and once in the body - and his wife and children without a husband and father.

The investigation into his murder stunned Scottish police and remains one of the most baffling unsolved cases in its history.

But two new leads and pioneering DNA technology have given police fresh hope they can finally find out what happened - and get justice for the Wilson family.

This weekend a gun, identical to the 1920s Haenel Schmeisser that killed him, turned up at a local house clearance sale.

A caller has also rang into a radio station saying they know more information about the crime. 

Police Scotland are also planning to re-run DNA tests on key pieces of evidence with new technology introduced in 2015 that tests 24 elements of someone's DNA - instead of the previous 11.

They think this could lead them to the murderer.

Speaking on the 13th anniversary of the killing this week, Detective Superintendent Gary Cunningham: 'Recently we have seen a number of theories and rumours put forward about the motive behind Alistair Wilson's murder.

'Our investigation has previously looked into these theories. As part of a thorough ongoing investigation we have to remain open-minded and will continue to review all scenarios.

'Additionally, we constantly review advances in forensic science. There has been significant investment in improving our DNA technologies in the last few years. 

'With the advent of DNA24, we are now obtaining DNA profiles from items which, when previously tested, had not produced a profile. 

'As such, we are continuing to review the items suitable for further testing in this case.
