The son of missing Derry man John Concannon has urged people to keep him in mind as the search enters its sixth week.
Edward Concannon (21) has been routinely searching along with other relatives, official teams and an army of volunteers across Derry and Donegal since his father went missing on November 10.
Edward said the past weeks have been “life-changing” and something he never expected to have to deal with.
“You never think one of your parents will go missing. You hear it about others but you don’t think it will ever happen,” he said.
John (71), who lives in Galliagh and who suffers from dementia as well as deafness, communication difficulties, disappeared after getting the wrong bus home. He was last seen walking along Lenamore Road in the direction of the border with Muff.
Edward said there have been no new leads in the search for his father recently.
“Nothing has come up,” he said. “It’s quite tragic. We are looking over the same areas, but we want to be extremely thorough.
“I was hoping he got a lift or shelter somewhere. I don’t know what I’m hoping now.
“We are just sitting here most of the time waiting for that one call, something that would put us further closer.”
Edward urged anyone who sees a person in apparent distress or who looks like they might need help to go to them and try to communicate with them and report it straight away if they think the person might be vulnerable.
He also said his father would have a beard now as it was unlikely he has shaved in the past six weeks and he might be different looking.
He described the support from neighbours and the community as “fantastic”.
