It’s been confirmed 24-year-old student Jastine Valdez was strangled to death.
She was last seen being forced into a car in Wicklow on Saturday evening.
Gardaí have launched a fresh appeal for information on the movements of her suspected abductor Mark Hennessy.
The dad of two left a blood stained note in his car before he was shot dead, expressing remorse for what happened.
A vigil for Ms Valdez is being organised this evening in her home village of Enniskerry in Co Wicklow.
An online fund set up to help the 24 year old’s family has raised more than €55,000.
Gardaí would like to speak to anyone who saw anything suspicious over the weekend in the area of Pucks Castle Lane and Murphy's Lane - or anyone using the Carrickgollogan Forest Recreation Area or the Lead Mines in Kiltiernan.
They’re particularly asking any hillwalkers, cyclists or drivers who used the area and may have a dashcam to contact them.

Local Wicklow TD John Brady said tonight's vigil is a chance for people to pay their respects to Jastine.
"People really don't know what to be doing or what they can do, but they want to show their support for Jastine's family - who are obviously going through a horrendous time at this stage.
"So they're organising a vigil at 7 o'clock at the clock-tower in Enniskerry village".
