Gardai have launched a fresh appeal for information on the movements of Mark Hennessy, the suspected abductor of Jastine Valdez.
They want to speak to anyone who may have seen the dad of two and his Nissan Qashqai car over the weekend.
They say the 40 year old may have stopped at restaurants, cafes, shops or petrol stations in South Dublin.
These areas include Dalkey, Killiney, Ballybrack, Sallynoggin, Cherrywood and Rathmichael.
A vigil is being held this evening for Jastine Valdez in her home village of Enniskerry.
