The 47-year-old from Buckie was reported missing to Police on Friday after his family raised concerns they had not seen or heard from him since Christmas Eve.
It has been more than three weeks now since Alan Morrison was last seen at his home at Lawson Place.
Police inquiries have been ongoing in the vicinity of the area to establish his last movements, with searches also launched in the area by specialist teams focusing on the Burn of Buckie.
Detective Inspector Norman Stevenson said: “To help with our searches I’m asking people who live in Buckie to check their gardens, sheds and any outbuildings to make sure that Alan hasn’t taken shelter.
“In addition if you are out walking in the area please keep an eye out for any sign of activity. All I ask is that you don’t put yourself in any danger.”
He added: “It is extremely concerning that Alan wasn’t in touch with his family over the festive period, in particular Christmas Day, and as more time passes our concerns for him understandably grow.
“Alan was last seen at his home on Christmas Eve but wasn’t there when his family checked on him on Christmas Day therefore he must have left that night. Did you see him that evening? Or do you have dash-cam footage of the area which may have captured him? I appreciate this footage may be wiped by now but if you do have information which could assist please let us know.”
Alan is described as being around 5ft 9, of a medium build with short dark and grey receding hair and a beard. He is believed to be wearing black Adidas Samba trainers, a long-sleeved dark T-shirt, a navy padded jacket and could also be wearing a beanie hat and gloves. He is also a heavy smoker.
Anyone with information should call Police on 101 quoting ref. no. 2636 of Jan 11.
