A jogger who is the last witness to have seen Dublin childcare worker Elaine O'Hara alive described her to Gardaí as "distant and uninterested".
Conor Guilfoyle is giving evidence at the trial of Graham Dwyer of Kerrymount Close, Foxrock who denies murdering the 36-year-old at Killakee, Rathfarnham, on August 22nd, 2012.
Mr Guilfoyle was jogging at Shanganagh at around 5.30pm on the night of Elaine O'Hara's disappearance.
He is the last witness to have seen the 36-year-old alive. He said he stopped to give her directions towards a footbridge by the railway line.
He said she was wearing a light blue raincoat and did not say thank you - like she had rather not engage in conversation.
He could pinpoint where he met her because he was using an app that timed and tracked the route of his run.
He told the jury he saw her again minutes later on the footbridge walking towards the sea.
It is the prosecution's case that Elaine O'Hara was in a sado-masochistic relationship with Graham Dwyer and that the architect murdered her in the Dublin mountains that evening for his own sexual gratification.
