An Garda Siochána said the area will be searched and subject to excavation, technical and forensic examinations over several days.

On Thursday, the excavators worked to heap up soil in large piles under the watch of investigating Gardaí.

One of the lines of inquiry being pursued by Gardaí is that prime suspect in the Deirdre Jacob murder, Larry Murphy, was seen burying a car in the area of the search several years ago. 

A source said: "Larry Murphy was seen burying a car in this area and that vehicle could contain significant evidence for the investigation."

Josephine “Jo Jo” Dullard went missing on November 9 1995 while on her way home to Callan in Co Kilkenny after socialising in Bruxelles bar on Dublin’s Harry Street.

The 21-year-old missed her last bus to Kilkenny and instead boarded a 10pm bus to Naas, Co Kildare, intending to hitchhike the rest of the way home.

She hitched a lift from Naas to the slip road on the M9 motorway at Kilcullen, Co Kildare, and at 11.15pm got another lift to Moone.

There, Ms Dullard called her friend Mary Cullinan at 11.37pm from a phone box.

During that call, Ms Dullard told Ms Cullinan that a car had stopped for her and she was going to take the lift.

Ms Jacob was last seen near her home at Roseberry, Newbridge, in Co Kildare at around 3pm on July 28 1998.
