Graham Dwyer's defence team has said that it accepts that the skeletal remains found at Killakee in the Dublin Mountains were those of Elaine O'Hara.
The 42-year-old architect with an address at Kerrymount Close, Foxrock denies murdering the childcare worker in August 2012.
The prosecution alleges Graham Dwyer was in a sado-masochistic relationship with Elaine O'Hara and that he stabbed her to death to satisfy his sexual desires.
The 36-year-old childcare worker was last seen near Shanganagh cemetery in Dublin on the evening of August 22, 2012.
Her partial remains along with tracksuit bottoms, and a runner were found by a dogwalker in a rough wooded area of the Dublin mountains on September 13 the following year.
Gardaí have this morning given evidence of preserving the scene – the defence does not deny that the bones found were those of Elaine O'Hara.
The dogwalker Magali Vergnet said she also saw a rusted knife, but gardaí who initially attended the scene said they do not recall being made aware of this.
