Architect Graham Dwyer, who is accused of the murder of childcare worker Elaine O'Hara, has been sent forward for trial after being served with an eight-volume book of evidence.

Mr Dwyer, who is originally from Cork, but has an address at Kerrymount Close, Foxrock in Dublin, is accused of the murder of Ms O'Hara, 37, in Co Dublin on 22 August 2012.

Her remains were discovered on Killakee mountain in Rathfarnham in September 2013, more than a year after she was last seen.

The 41-year-old married father-of-two was charged on 18 October and when asked if had anything to say, he replied: "I do, not guilty".

He was subsequently refused bail and today appeared again at Cloverhill District Court before Judge Victor Blake.

Detective Sergeant Peter Woods served the book of evidence on the accused, who was then given the standard warning by the judge that if he intended to use an alibi in his defence he must notify the prosecution within 14 days.

He replied "understood" and the judge then told him that he was making an order sending him forward for trial to the present sittings of the Central Criminal Court in respect of the single charge in the book of evidence.

Judge Blake said that Mr Dwyer had already been granted legal aid and defence solicitor Jonathan Dunphy said that in relation to this issue there had been no change.

Solicitor Ronan O'Brien, for the Director of Public Prosecutions,, asked for a section 56 order to be made in relation to providing the defence with video evidence.

However, this has already been complied with, Mr Dunphy explained.

The court heard that one volume of the book of evidence contained statements and the other seven involved the exhibits.

At a previous hearing, the prosecution said the file on the case was quite large.

Gardaí had taken more than 300 statements and have in excess of 800 exhibits, the court has also been told.

In November, the district court ruled that Mr Dwyer could be granted legal aid as he is no longer on a salary and a mortgage on his family home was in arrears.

Ms O'Hara, from Killiney in Dublin, was last seen on 22 August 2012.

The 37-year-old's remains were found in undergrowth by a woman walking her dog on 13 September last year on Killakee mountain.

A bag containing several items belonging to her were found near Roundwood in Co Wicklow at different times in the days before and after the discovery of her body.

The opening of an inquest into her death heard that no cause of death has been established. The inquest has been adjourned until the outcome of criminal proceedings.
