The prosecution will finish summing up its case to the jury in the Graham Dwyer murder trial later this morning.

The architect from Kerrymount Close, Foxrock denies fatally stabbing childcare worker Elaine O'Hara at Killakee Mountain in Dublin in August 2012.

Sean Guerin for the prosecution spent around 3 hours on his feet yesterday tying together the various strands of evidence against Graham Dwyer.

He'll complete that task this morning.

He alleges the architect manipulated a lonely and troubled Elaine O'Hara as part of a predatory sexual relationship and finally lured her to Killakee to live out his deep seated sexual fantasy of stabbing a woman to death during sex.

It's their case Graham Dwyer was fully aware the childcare worker had been in a psychiatric hospital and that her death could be seen as suicide.

Once the prosecution finishes, Remy Farrell for the defence will address the jury.
