Gardaí have issued a renewed appeal for information, in relation to her disappearance and murder.
Searches have been ongoing on the farmland located near Grangecon on the Wicklow/Kildare border - with Gardaí issuing an update to say they expect the operation to continue over the weekend, and early into next week.
It comes almost a week on from the 29th anniversary of Jo Jo Dullard's disappearance.
The 21-year-old from Callan in Co. Kilkenny was last reported to have been in Moone County Kildare, on November 9th, 1995.
The open ground, where the search operation is currently taking place, is understood to be located around 15 minutes away from Moone.
A man was arrested earlier this week in connection with the investigation into Jo Jo's disapearance and murder - but has since been released without charge.
Gardaí are appealing to anyone with any information, to contact them.
