The sister of missing Jo Jo Dullard has urged anyone with information to come forward - saying the family would be 'so grateful' and that they don't want revenge.
She has called on people who know something about the disappearance to 'break their silence', and to not be afraid about doing so.
21-year-old Jo Jo went missing from Moone in Co Kildare on 9th November 1995.
She had been travelling home to Co Kilkenny from Dublin, but decided to hitch lifts after only missing the last bus home and only being to travel part of the way.
After ending up in Moone, she rang a friend from a phone box to tell her where she was - then saying a car had stopped for her.
Shortly after, a woman matching Jo Jo's description was seen leaning in the back door of a dark-coloured Toyota Carina type car.
It was the last known sighting of the 21-year-old.
Gardaí earlier this year upgraded their investigation into the disappearance to a murder inquiry, while Jo Jo's family continue their campaign for answers.
Today marks National Missing Persons Day, and Jo Jo's sister Kathleen Bergin spoke to Lunchtime Live.
She said it's hard to believe 25 years have passed since the disappearance.
She told Andrea: "It’s so hard to explain to people exactly what it’s like. It has been devastating for our family - we never thought we’d be here 25 years after, still looking for answers and asking people to come forward and help us.
“We know somebody knows something, but for whatever reason they’ve kept their silence. We’re asking them now to break their silence and tell us where she is."
She said Jo Jo was making a journey home, and the family wants her to be able to finish that journey.
'We just want Jo Jo back'
Kathleen said the disappearance of Jo Jo has affected her family, friends, neighbours and people who watched her grow up.
Some of those who knew Jo Jo have since passed away, and Kathleen says it's 'heartbreaking' to know they never got the answers they wanted.
She said: “Ireland’s a small country - I thought in the beginning we’d find her. But it’s like searching for a needle in a haystack.
"I want people to know if they’re afraid to come forward, [don’t] be afraid. We’re so grateful to people coming forward.
“We just want Jo Jo brought back - we don’t want revenge. We pray for them to have the courage and strength to come forward."
She said recent appeals have led to new information being provided, so she urged people to pass on anything they might know about what happened 25 years ago.
