Graham Dwyer, originally from Cork but with an address at Kerrymount Close, Foxrock, Dublin 18, is accused of the murder of Ms O’Hara, aged 37, a childcare worker, in Co Dublin on Aug 22, 2012.
The 41-year-old architect had been detained for questioning at Blackrock Garda Station overnight before being brought to appear at Dún Laoghaire District Court on Oct 18.
At that hearing, Det Sgt Peter Woods had said Mr Dwyer had been cautioned and, when asked if had anything to say after he was charged, he had replied: “I do, not guilty.”
He was remanded in custody and yesterday appeared before Mr Justice Paul Butler at the High Court, sitting in Cloverhill, Dublin, to make a bail application.
Gareth McCormack SC, for Mr Dwyer, urged the High Court to consider granting Mr Dwyer bail, saying Mr Dwyer’s father was in court and was prepared to act as an independent surety and would stand €25,000 bail for his son.
It was also proposed that Mr Dwyer could reside at an address in Bandon, Co Cork, and the court was asked to take into consideration that Mr Dwyer, if denied bail, could spend a lengthy period in custody pending his trial.
Supt Diarmuid O’Sullivan outlined objections to bail to prosecution barrister Eoghan Cole SC.
Following submissions, Mr Justice Butler refused to release Mr Dwyer, who remained silent throughout the hearing.
He will face his next hearing at Cloverhill District Court on Nov 20, when the issue of whether he is to be granted free legal aid is to be decided.
Ms O’Hara, from Killiney, in Dublin, was last seen at about 6.15pm on Aug 22, 2012, near Shanganagh cemetery in south Dublin, where her mother is buried.
Her remains were found in undergrowth by a woman walking her dog on Sept 13 on Killakee mountain, Rathfarnham. A bag containing several items belonging to her were found near Roundwood, Co Wicklow.
