Second Hillwalker Dies In Hospital
A second hillwalker who was among a group of three elderly men rescued after being missing overnight has died.
A large-scale search was launched for Bobby Thomson, 64, George Crosbie, 73, and Geoffrey Stewart, 74, after they failed to return from a walk in the hills around Durisdeer in Dumfries and Galloway on Tuesday afternoon.
The men were found 2.5 miles east of the village on Wednesday following a search involving police and mountain rescue teams, and they were airlifted to hospital.
Police confirmed shortly afterwards that one man had died. He was later named as Mr Crosbie.
Police have also now said Mr Stewart died in hospital late on Wednesday night.
Mr Thomson is recovering in Dumfries and Galloway Royal Infirmary.

Rachel Slater, 24, and Tim Newton, 27, failed to return from an outing on Ben Nevis in the Scottish Highlands at the weekend.
It is believed the experienced climbers, from Bradford in West Yorkshire, had been camping behind the Charles Inglis Clark memorial hut on the north side of the mountain.
The alarm was raised on Monday afternoon when the couple were reported to be overdue in returning from the expedition.
Heavy snow, fog and high winds prevented teams from carrying out detailed searches for them on Wednesday and an avalanche elsewhere saw a rescue helicopter diverted from the hunt.
Two men were airlifted from the Creag Meagaidh area of north Lochaber following the avalanche and one of the climbers later died in hospital. The other remains in a serious condition.
