Gardaí investigating the discovery of the remains of a 36-year-old woman the Dublin mountains have sealed off a second crime scene in Co Wicklow.

The remains have been identified as those of Elaine O’Hara from Killiney in Dublin.

She had been missing for the past 13 months.

Gardaí have also discovered a number of personal items belonging to Ms O’Hara near a reservoir in Roundwood, around 8km from where her remains were found.

Ms O'Hara was seen leaving Belarmine Plaza in Stepaside on Wednesday 22 August.

She was later seen close to the railway footbridge at Shanganagh Park in Shankill.

She had been unwell and had only recently been discharged from hospital.

Her father reported her disappearance to gardaí and her car was found at Shanganagh Cemetery at 3pm on Friday 24 August.

Her remains were discovered last Friday in a private forest by a woman out walking her dog.

Gardaí are trying to establish how she got to Killakee Mountain, which is about 15km from where she was last seen alive.

A second crime scene has been sealed off at a reservoir at Roundwood in Co Wicklow.

Last Wednesday, a number of items, including one relating to Ms O'Hara's work and material that could have been used for restraint, were found there and handed into gardaí.

A further search of the area yielded more personal items, including clothes believed to belong to Ms O’Hara and today the Garda Underwater Unit searched the reservoir.

The cause of Ms O'Hara's death has not been established, but gardaí are treating it as suspicious and carrying out a criminal investigation.

They have issued an appeal for anyone with information to come forward.
