Shaun was reported missing on Sunday 2 November 2014 after last being seen in the Strichen area of Aberdeenshire on Friday 31 October 2014.
Since Shaun was reported missing extensive searches have been carried out making this one of the biggest ever search operations carried out by Police Scotland. Officers have also used the expertise of a forensic soil scientist and a geoscientist to assist with the enquiry.
The circumstances surrounding Shaun's disappearance have been reviewed by the Major Investigation Team based in Glasgow, which included a review of the forensic work carried out in the investigation, and the search activity has also been reviewed by Police Scotland specialist search advisors and the National Crime Agency lead search advisor.
To date these reviews have all concluded that this remains a missing person inquiry and there is no evidence to suggest that Shaun has been the victim of any crime.
Officers at Police Scotland will continue to keep an open mind regarding the circumstances of this investigation and can provide every assurance that any new information provided to us will be acted upon.
