Sex site user tells Elaine O'Hara trial of cut marks on her abdomen

A court has heard Elaine O'Hara complained to a man she met on an adult website about non-consensual cutting marks on her abdomen.

It was heard in the trial of 42-year-old architect Graham Dwyer of Kerrymount Close, Foxrock, who denies stabbing Elaine O'Hara at Killakee Mountain in Dublin in August 2012 for his own sexual gratification.

The court heard from a number of witness who made contact with Ms O'Hara on sex web sites.

One of them, Mark Guerin, used the moniker time2killinDublin on alt.com which the jury has heard is a website for people who like to be submissive or dominant in sexual relations.

He gave evidence Elaine O'Hara was nervous when he visited her bedsit accommodation in Blackrock about five years ago.

He agreed with the prosecution that she spoke about self harming, another partner she had had, and cutting marks on her abdomen that were not consensual.

He said he did not have sex with her that time but did on another occasion.

However, he concluded they were not compatible for play as she was into "restraint, degradation and blood letting" and he liked "light kink".

The trial continues.
