Bernadette Connolly's daughter Jade is continuing to appeal for new information four weeks on from the 45-year-old's disappearance.
She has vowed she "can't give up" until she finds her mam and is requesting anyone in the Malahide area to check CCTV for any trace of Bernadette.
New CCTV footage from a house near the public toilets on Malahide beach shows Bernadette in the distance on Donabate Beach at 12:46pm on Friday January 7.
