Volunteers search for missing Gwyn Morris, 88 27 December 2012 Last updated at 10:58 Volunteers are searching for an 88-year-old man missing from a Hertfordshire care home, three weeks to the day after his disappearance. Gwyn Morris went missing from his home in Stanstead Abbotts on 6 December, People were asked to meet at the Jolly Fisherman pub on the town's High Street at 11:00 GMT on Thursday. Mr Morris' daughter Ann Hawker, who organised the search through social media, said "I'm just desperate, I don't know what else to do." "I have been so anxious over Christmas, I needed to be doing something and I just wanted to get something going," she added. He could conceivably be anywhere. Mr Morris' family has turned to Facebook for help while Hertfordshire Police continue the hunt and the search has been organised through the Help Find Gwyn Morris page. The family has posted photographs of Mr Morris online and are also discussing his disappearance on Twitter using the phrase #HelpFindGwyn. Nationwide publicity Mrs Hawker's husband Robin Hawker said Thursday's search was not just about trying to find Mr Morris in the area, but also to get the story in the public eye and "keep the hope going." "You hear stories of people being found several months later out of the district," he said. There is not a great deal of hope of him being found safe and well unless he has been taken in at a hostel and has not been recognised. But he could have got some distance and if he did get a train and got to the centre of the country, there hasn't been a great deal of nationwide publicity. It is thought Mr Morris, who has dementia, may have been trying to return to Wales where he grew up and still has family ties. Police have described missing Mr Morris, whose family ran a farm at Llangurig, Powys, as "extremely vulnerable." He is described as 5ft 4in (1.62m) and medium build. He has short, balding grey hair. Officers said they would be supporting the search and giving the volunteers maps of the area and advice.
