Gardaí in Kildare have renewed an appeal for information in relation to Deirdre Jacob who has been missing for 21 years today.
Deirdre was last seen crossing the road towards her home at Roseberry, Newbridge, Co. Kildare, at around 3pm on Tuesday, July 28, 1998.
The family of the trainee teacher are hopeful progress can be made in the Garda investigation.
She was 18 years old at the time, five foot three inches tall with a slim build, grey/green eyes and dark chin-length hair.
She was wearing a navy v-neck t-shirt with a white trim-on collar and sleeves, navy or black straight jeans and blue Nike runners.
She was carrying a distinctive black satchel type bag with long shoulder straps and the word CAT in large yellow capital letters was printed on the front of the bag.
The bag has never been found and Gardaí are appealing for any information "no matter how small".
Officers are also interested in hearing from anyone who has ever found or noticed a bag similar to this.
Her father Michael has again urged anyone with information to come forward to gardaí.
He told Newstalk’s Breakfast with Susan Keogh: “They’re in the final stages of that case… that review will probably come to conclusion within the next couple of months.
“That then will give the detectives on the review case the go-ahead to add those to the great mix of information and hopefully progress the case.”
Deirdre had been visiting her grandmother before she disappeared.
Anyone with information is asked to contact Newbridge Garda Station at 045-431212, the Garda Confidential Line at 1800 666 111 or any Garda Station.
