An Post will distribute leaflets today seeking information about the missing woman, Ms Deirdre Jacob (18), to 6,000 houses near her home in Newbridge, Co Kildare.
Local gardai say they have had a good response to a reconstruction of the student teacher's last-known movements on July 28th which was broadcast on RTE television news on Tuesday evening.
The incident room in Newbridge Garda station received dozens of calls, according to a spokesman, but yielded no new information.
Ms Jacob was last seen about 300 yards from her home on the Barrettstown Road, a mile outside Newbridge.
Her father, Mr Michael Jacob, yesterday renewed his appeal to farmers and land-owners to check their premises for any clues. "Someone out there could have a tiny piece of information that might be exactly what the gardai need," he said.
Gardai are still anxious to talk to anyone who walks the Hawkfield Bog, about a mile from Ms Jacob's home. A girl roughly matching Ms Jacob's appearance was seen walking there at about 5 p.m. on the day she disappeared. But she was believed to be wearing a tracksuit and carrying a rucksack. Ms Jacob was probably wearing navy jeans and carrying a shoulder bag with the CAT logo.
Garda underwater teams yesterday continued their search of the Liffey nearby, while Civil Defence and local volunteers searched fields and hedgerows.
Anyone with information should contact the Garda in Newbridge, tel: (045) 431212, or the Garda confidential number 1-800 666111.
