Mobile phone records are to be examined by Gardaí investigating the discovery of the remains of Elaine O'Hara.
A cause of death has yet to be established while searches will continue today at Kilakee Mountain in Dublin for further remains.
The 36-year-old was last seen alive leaving her home at Belarmine Plaza in Stepaside on Wednesday evening, August 22 last year - the day before the Tall Ships festival kicked off.
Her car, a turquoise Fiat Punto was found by Gardaí at Shanganagh cemetery, two days later.
Gardaí have said they are following a number of lines of enquiry - after Elaine's personal belongings, as well as instruments that could be used for restraint - were discovered at Roundwood reservoir in Co.Wicklow.
Garda Spokesperson Superintendent David Taylor, said the O'Hara family, has asked for privacy at this difficult time.
"The family are quite upset they understand that they media are interest but they are asking for privacy at this time to grieve in private," he said.
"They have got Elaine back which is of great comfort to them and I think it beholds all of us to give them space and time to grieve."
