Search continues for missing hillwalker in the Highlands
Neil Gibson went missing with his brother Alan, who has since been found dead.
Rescuers are continuing their search to find a hillwalker who went missing with his brother in the Wester Ross.
Neil Gibson, 63, was reported missing with his brother Alan, 56, and a black pointer dog called Archie after going walking in Strathcarron on Thursday morning.
The body of Alan Gibson, who was from Durham, was discovered by search teams on Saturday.
They returned to the area on Sunday as to continue their search for Neil in the Achnashellach area and will stay out until last light.
It has emerged that Neil, from Nairn, helped save a US woman's life while working as a golf caddy in the town in 2013.
Marilyn Holter, a retired lawyer from New Jersey, was playing at Nairn Golf Club in the Highlands when she became unwell, showing symptoms of a cardiac event.
Neil, who was caddying for her, persuaded Mrs Holter to let him take her to Nairn Town and County Hospital, from where she was taken by ambulance to Raigmore Hospital in Inverness.
He then returned to the course to collect Mrs Holter's husband, driving him to Raigmore Hospital to be at his wife's bedside.
She spent two nights being treated for a heart condition before being released to continue her recovery at home.

Mrs Holter later said: "Although I am not a doctor, I am convinced that Neil's actions were not only wildly and unusually considerate, but also life-saving."
She thanked him "for caring so much and so effectively for a couple of strangers".
He also won praise from the golf club's manager and the tour company who had organised Mrs and Mr Holter's trip.
Neil was quoted as saying at the time: "It's nice to receive praise but I just did what I thought was right and thankfully things worked out well.
"Nairn caddies like to show consideration to their clients."
The search for Neil is being carried out by Torridon, Dundonnell and RAF Lossiemouth Mountain Rescue Teams, Coastguard Rescue Helicopter and the Search and Rescue Dog Association.
