DNA samples recovered during forensic examinations of the area are to be compared with DNA samples taken from witnesses known to have been in the area subsequent to the murder of Alistair Wilson, with the aim of eliminating them from the inquiry.

UPDATE: (Friday 4FEB05 00.40 GMT) DNA tests on witnesses are to be carried out at Nairn Police Station over the next two days.
