A jury has heard that Elaine O'Hara told her father she had been seeing a married architect from Foxrock for four years, since 2008, and that she had asked him to kill her but he would not do it. O'Hara's father, Frank, also told the court that his daughter told him the man tied her up and performed sex acts with her.

A pathologist who examined the skeletal remains of Elaine O'Hara has told a jury he could not establish the cause of her death.

Architect, Graham Dwyer of Kerrymount Close, Foxrock denies murdering the 36 year old at Killakee in the Dublin mountains in August 2012.

The jury also heard Elaine O'Hara's remains were found by a dog walker in the Dublin mountains in September 2013, more than a year after her disappearance.

Deputy State Pathologist Dr Michael Curtis said around 60-65 per cent of her skeleton was found along with tracksuit bottoms, a running shoe and a sock. The court heard Ms O'Hara's skull was not found in the search.

He said the cause of death is undetermined but he did not rule out a stabbing.

The jury heard Elaine O'Hara was discharged from a psychiatric hospital and picked up a number of medicines including anti-depressants on the day of her alleged murder.

Women she worked with at a newsagents in Blackrock gave evidence that the 36 year old worried about money, had mentioned a married man, and a bondage web site.
