A Dublin woman is among the people featured on a BBC programme aiming to reunite vulnerable missing men and women with their families.
Ellen Coss, who would now be 56, has not been seen since November 3rd, 1999, when her sister dropped her off at Manchester's Piccadilly Station at the start of a trip back to the Irish capital.
She never arrived back in Dublin. Her story is one of those being featured on BBC1's Missingseries, which is being shown every week night for two weeks in the run-up to Christmas.
The programme's production crew were given unprecedented access to the National Missing Persons Helpline, the UK's only charity dedicated to finding missing people.
Ellen's brother Tom Brown said: "This is a chance to highlight Ellen and to make people aware of how much we miss her and what we go through day to day.
"The National Missing Persons Helpline charity has been a fantastic support for all of Ellen's family and I don't know how I would have coped without them."
Ellen is described as being five feet, three inches talll; of slight build; with long greying dark brown hair that she usually ties back. She was supposed to be travelling back to Ireland by ferry from Holyhead, but she never arrived home.
Anyone with any information about Ellen's whereabouts should contact the helpline on 00800-70007001 (from Ireland) or 0500-700700 (from Northern Ireland).
The programme featuring her will be shown on December 21st on BBC1 at 9.15am.
