Gardaí have renewed an appeal for information about the whereabouts of Imelda Keenan, who disappeared in Waterford city 31 years ago.
Ms Keenan, who was originally from Mountmellick, Co Laois, had moved to Waterford and was living with her boyfriend.
On the day she disappeared, the 22-year-old woman was seen as she left her apartment at 1.30pm on 3 January 1994, and walked down William Street onto Lombard Street.
The last confirmed sighting of her was at the corner of the Tower Hotel and Lombard Street, where she was seen crossing the street.
Ms Keenan was reported missing by her brother, Edward, the following day.
Despite extensive garda investigations, there have been no further confirmed sightings of her.
If Ms Keegan is still alive, she would now be 53 years old.
Garda Superintendent Gavin Hegarty said: "Imelda was known for her quiet demeanour, her love of music and her strong family ties. Despite extensive investigations spanning 31 years, the silence surrounding her fate remains unbroken.
"We continue to urge anyone with information or the ability to assist our investigation to come forward."
Anyone with information is asked to contact gardaí at Waterford Garda Station on 051 305 300, the Garda Confidential Line on 1800 666 111, or any garda station.
