The family of Jo Jo Dullard have thanked the public for their support as the search for her continues, and have asked them to "keep the candle of hope burning to help her find her way home".
Ms Dullard went missing 29 years ago as she was on her way back to Kilkenny from Dublin on 9 November 1995.
The 21-year-old was hitchhiking home to Kilkenny, and took a lift at Moone in Co Kildare, and has not been seen since.
The missing persons investigation was upgraded to murder four years ago.
In a statement this afternoon, her family said that she was "all alone and had no one to help her" on the night she went missing, adding that "you can help her now."
"Jo Jo has suffered enough and deserves to be laid to rest beside her Mam and Dad," they added.
They continued: "We would like to thank everyone for all the lovely messages and prayers during this time.
"We really feel that both our local community and the country as a whole have been behind us every step of the way.
"We cannot put into words how much we appreciate and cherish this support."
They have asked that people keep Ms Dullard in their prayers, and appealed for anyone with any information "no matter how small" to come forward.
