The mum of one of Ireland's most high-profile missing women has revealed that she will never see her daughter again.
US student Annie McCarrick vanished after a night out in the Johnnie Foxes in March 1993.
The Garda Serious Crime Review Team or ‘Cold Case Unit’ has now taken over the case.
Speaking on Monday's Crimecall, Annie's mother Nancy told presenters it was a "terrible loss" and she now just wants to get her daughter's body back.
She said: "And it’s been a long time, such a very long time. I’m pretty sure you know that I’ll never see her again.
"But I guess my greatest wish would be to be able to take her home. And have a grave that I could go to.
"So to find out what happened to her really would be a great gift at this point. It really would."
When the Cold Case unit become involved in a case their role is to open up all possibilities in the investigation and review all the information gathered to date.
Working with local detectives, they introduce a ‘What if’ to everything, and in this way, generate new lines of enquiry to move the investigation forward.
Nancy travelled from her home in New York, to talk to Crimecall and the Cold case team about her daughter’s disappearance.
Detective Superintendent Walter O’Sullivan said Annie was just 26 when she vanished 23 years ago.
"Investigators investigating her disappearance collected information at the time, to say that Annie visited Johnnie Fox’s Pub here, in the village of Glencullen, high in the Dublin Mountains.
"The information suggests that she was sometime here in the pub between 9pm and 11pm. It was Friday, it was the 26th March, it was 1993."
Det Supt O'Sullivan explained that the student loved to walk in the village of Enniskerry in Co Wicklow.
Investigators know that she took the 44 Bus from Ranelagh to Enniskerry at approximately 3.40pm.
"We are reasonably satisfied that her journey took her beyond Milltown, but did she reach the village of Enniskerry?
"Would she have walked from Enniskerry to Johnnie Fox’s on that cold, wet, miserable evening?
"Enniskerry is 6km away. It would have been dark. It would have possibly been between 8 and 9 o’clock when she embarked on her journey. Would Annie have walked this road?"
