A GARDA investigation file into the death of childcare worker Elaine O'Hara contains more than 300 statements and 800 exhibits, a court has heard.
Graham Dwyer (41) appeared via videolink before Cloverhill District Court this morning and Detective Sergeant Peter Woods outlined the extent of the investigation into the killing of Ms O'Hara.
Sgt Woods said the garda investigation is at an advanced stage and he expects the file will be ready in the next two weeks to go to the DPP's office for directions.
Sgt Woods said the garda investigation into the death of 37-year-old Elaine O'Hara contains 441 lines of enquiry, 336 statements, 349 reports and 814 exhibits.
Dad of two Dwyer, of Kerrymount Close in Foxrock, is charged with the murder of Elaine O'Hara, whose remains were found in the Dublin mountains on August 22, 2012.
Earlier this month Dwyer, an architect who is originally from Cork, was denied bail at the High Court.
The accused, who appeared before the court via videolink from Cloverhill Prison, was wearing a grey tracksuit and black polo t-shirt. He spoke to the court only to confirm his name and that he understood proceedings.
He also leaned forward, with his hands clasped on his knees, to better hear what was happening in the courtroom.
Defence solicitor Jonathan Dunphy told Cloverhill court his client was anxious for matters to be progressed.
Sgt Woods outlined the extent of the garda investigation into Ms O'Hara's murder, saying the file is almost ready to go to the DPP's office.
He said the file contains 441 lines of enquiry, 336 statements, 349 reports and 814 exhibits.
Mr Dunphy said there was consent to a four week remand in custody for DPP's directions on the charge.
Mr Dunphy also applied for free legal aid, saying gardai had no objection to it.
Judge Grainne Malone said she had a statement of means signed by the accused, and it appeared he comes under the legal aid scheme.
However, Judge Malone said there were a number of matters which she wished to clarify with the accused.
The judge ordered that Dwyer be produced in court, and she let the matter stand until later today.
Childcare worker Ms O'Hara, who also had a part-time job in a newsagents, was last seen at around 6.15pm on August 22, 2012 last year, near Shanganagh cemetery in south Dublin, where her mother is buried.
Her skeletal remains were found in undergrowth by a woman walking her dog on September 13 this year on Killakee mountain, Rathfarnham.
Several items belonging to Ms O'Hara were found near Roundwood, Co Wicklow, at different times in the days before and after the discovery of her body.
Dwyer has been remanded at Cloverhill Prison since he was formally charged last month. Asked by Detective Sergeant Peter Woods if he had anything to say after charge, Dwyer replied "I do - not guilty".
The accused, a married man with two children, is a member of the Royal Institute of Architects of Ireland. He is a director of the A&D Wejchert & Partners firm on Baggot Street.
Ms O'Hara, from Belarmine Plaza, Stepaside, had been missing for more than a year when her partial remains were found.
