A heartbroken man has told of his family's desperate attempts to find his missing 81-year-old brother who has dementia.
The family of James (Jim) Wilson believe he may been trying to find his old family home and are now frantically searching country roads for him.
Jim Wilson has not been seen since 8.30pm on Tuesday night when he left the Hamiltonsbawn Road nursing home where he was living.
His brother David has appealed to the public for help in locating him in the Hamiltonsbawn area as the old family homestead in Tassagh is just eight miles away.
"The biggest worry for him is the cold but we are just hoping that people will keep an eye out for him," said David Wilson (66) last night.
"We are very worried about him at the moment. We have exhausted everything we can think of, searched every road, every nook we can find and have even gone to Dundalk.
"But with a missing person, until you find out where they are, there's no closure."
Jim Wilson is described as being approximately 6ft tall, of medium build with grey hair and had been wearing a blue, tweed jacket, blue trousers, a white shirt and a striped tie.
David Wilson told the Belfast Telegraph that his elder brother had lived for 60 years in north Wales with his wife where he worked in several hydro-electric stations.
After his wife died three years ago, the family took Jim back home to Northern Ireland to be cared for as the couple had no family of their own.
Mr Wilson said: "A dementia patient at some point always wants to go home but he was happy living at the nursing home for the last two years."
"Jim may be confused but he is a very placid type of man.
"Apart from suffering from dementia, he would be a very fit man for his age.
"We just don't know if he has got himself in somewhere for shelter."
He said that there had been a concerted local effort to locate his brother, led by the PSNI, but also supported by his wider family circle and friends.
The family have distributed posters of Jim locally and have launched a separate Facebook appeal for information.
Armagh police are appealing for anyone who may have spotted the missing man to ring them on 101.
