No DNA from gun in banker murder

Alistair Wilson was gunned down on his doorstep nine months ago

New forensic tests on the gun used to kill Nairn banker Alistair Wilson have failed to uncover any trace of DNA.

Northern Constabulary had taken swabs from the inside of the firearm, after earlier tests on the outside of the gun did not find any useable material.

Detective Chief Inspector Peter MacPhee had said the tests would be probably be the last chance to get any forensic evidence from the handgun.

Mr Wilson was killed on the doorstep of his home in November last year.

No motive

The semi-automatic gun was found in a drain near to Alistair Wilson's home 10 days after his murder.

Northern Constabulary said they would continue to try to trace the weapon's origins.

About 40,000 of the guns were produced in Germany in the 1920s and police suspect the weapon may have been brought back to the UK either as a war trophy, for legitimate export or on the black market.

Police have still not established a motive for the murder.
