Gardaí investigating the disappearance of Co Wexford woman Fiona Sinnott in 1998 are expected to continue their search of a Wexford field in the morning.
The dig began yesterday in a beet field in Killinick, Co Wexford, and a large steel barrier remains placed around the excavation site.
Today's dig was called off at around 4pm. It is understood an archaeological team used a radar scanning device to ascertain if the earth had been disturbed in the last number of years.
Ms Sinnott, the mother of a baby girl, has been missing since February 1998.
The Garda investigation into her disappearance has been one of the most intensive conducted in the State.
Ms Sinnott went missing after leaving a pub near her home at Our Lady's Island in Co Wexford on February 8th, 1998. She was the youngest of five brothers and sisters.
Last September six people were arrested in connection with her disappearance. They were subsequently released without charge.
In 1999 detectives involved in Operation Trace, the Garda investigation into the cases of six missing women came to Wexford but failed to turn up any new leads.
Afterward, gardaí were said to be satisfied there was no link between Ms Sinnott's case and others.
Operation Trace was set up seven years ago by then Garda commissioner Pat Byrne to review the files of Ms Sinnott, Josephine Dullard, Deirdre Jacob, Ciara Breen, Fiona Pender and Annie McCarrick.
