Graham Dwyer: Killer appealing murder conviction
An architect in the Republic of Ireland has lodged an appeal against his conviction for murder.
Graham Dwyer, 42, from Foxrock in south Dublin, was given a life sentence for the murder of 36-year-old Elaine O'Hara.
Her remains were found in the Dublin mountains in September 2013.
Dwyer had denied murder but was convicted by unanimous verdict at the Central Criminal Court in Dublin last month.
A judge told the court Dwyer had preyed on Ms O'Hara to satisfy his "perverse and debauched desires".
During the trial, the married father admitted having an affair with his vulnerable victim, a childcare worker, whom he met through a website.
The trial heard evidence that he and Ms O'Hara had a bondage and sadomasochist relationship in which he was the master and she was the slave.
The court was told that he fantasised about stabbing a woman to death for sexual gratification.
She was last seen on 22 August 2012, the day of her murder and had been missing for more than a year before her remains were discovered.
The jury found that Dwyer stabbed Ms O'Hara to death on Kilakee Mountain in Rathfarnham on 22 August, 2012, the day she left a psychiatric hospital.
