MURDER accused Graham Dwyer told detectives he could not explain why he visited gore websites but that he knew it was sick, the Central Criminal Court has heard.
The architect was being questioned by gardaí investigating the death of Elaine O'Hara about images and files retrieved from his mobile phone - which was synchronised with his laptop. The phone was seized the morning of his arrest, October 17, 2013.
Mr Dwyer (42) denies murdering Ms O'Hara (36) in Killakee, Rathfarnham, on August 22, 2012.
Det Sgt John Colgan, of the National Bureau of Criminal Investigation, interviewed the accused for a fifth and final time in Blackrock Garda Station at 5.47am on October 18, 2013.
One document put to the murder suspect had two images of what appeared to be the same female from Lovelydisgrace.com, the jury heard.
One was entitled "17 year old girl immobilised, gagged and then killed on her bed with more than 80 stab wounds all over her body."
"I would have looked at these websites on my laptop, they are gore websites, again concerned with horror," Mr Dwyer said.
He was asked why he needed to go on the sites.
"I can't explain, I know it's sick," said Mr Dwyer.
The suspect was also asked about several items from a YouTube application including "Close up stabbing" dated May 26, 2013; "Woman stabbed prison guard," dated on April 23, 2013; files titled "Stabbing" and "Stabbing 3"; as well as "woman strangled" and "woman strangled yoga," dated May 30, 2013.
"I wouldn't dispute it but I have to say I never strangled anybody," Mr Dwyer replied.
When asked about another document that contained an item entitled "submissive" -with contact values "submissive hyperlink mail to 391@Gmail.com" - he replied: "Is it Elaine O'Hara?".
Mr Dwyer told Det Sgt Colgan he was not guilty of the offence he was presented with.
"From what I have heard today and from what I knew before today, there are other people you should talk to as well as me and that is not being done in my opinion," he added.
He was asked what people?
"Anybody else like me who has been in contact with Elaine O'Hara," he replied.
One of the leading investigators on the case, Det Sgt Peter Woods, earlier admitted it was "disgraceful" that a source within the gardaí leaked information to the media the day of Mr Dwyer's arrest.
He agreed with Remy Farrell SC, Mr Dwyer's defence counsel, that "some" of the details about the suspect being a professional from Foxrock and Ms O'Hara visiting niche websites, must have emanated from the gardaí.
Mr Farrell said there had been a "full-blown media frenzy" that day and described it as the "worst leaking in the history of the gardaí."
"I think it's disgraceful that that information was out there to be honest," said Det Sgt Woods. "It's not something that helps the investigation or anybody."
The court was also told that Det Sgt Woods - who took Mr Dwyer's DNA the morning of his arrest - had never been told that more senior officers had taken items from Mr Dwyer's rubbish bin weeks before his arrest.
"You became aware weeks after all of this that in fact Chief Superintendent (Diarmuid) O'Sullivan had arranged to go rummaging through Mr Dwyer's bins some weeks before and taken a can of Turtle Wax," said Mr Farrell.
"That's right," Det Sgt Woods said. "But it was never capable of being used as evidence," he added.
The State's final witness - Detective Garda Darren Kerins - gave evidence about journeys he was asked to travel and time.
These included Mr Dwyer's workplace on Baggot Street, Dublin, to Quinn's Road Park in Shankill; from Killakee mountain to Mr Dwyer's home at Kerrymount Close; via Roundwood reservoir; and from Carrickmines to Kilakee Mountains.
"That is the evidence for the prosecution," said Sean Guerin SC, whose team had presented 327 exhibits and 194 witnesses over 37 days.
Mr Justice Tony Hunt then told the jury to "take a break" until next Wednesday, when the defence is expected to start its evidence. He also told them not to discuss the case with anyone outside the jury and to avoid media coverage. "The only opinions that are important are your opinions," Judge Hunt added.
