The barrister for a Dublin man who strangled his ex-girlfriend in a city hotel has said the totality of the evidence supported his client having a mental disorder.

However, the prosecutor said the accused “well knew” that what he was doing was wrong, was well able to control himself and there could not be any question of diminished responsibility due to such a disorder.

The barristers were giving their closing speeches on Friday in the Central Criminal Court trial of Eric Locke, who used a fake Facebook profile to meet Sonia Blount after she had cut contact with him.

Mr Locke is charged with murdering the mother-of-one in a room at the Plaza Hotel in Tallaght on February 16th, 2014.

The 35-year-old, with an address at St John’s Park East in Clondalkin, has pleaded not guilty, but admits causing the 31-year-old’s death.

He strangled her with hands and the cable of her phone charger and pushed her T-shirt into the back of her mouth.

Remy Farrell SC, prosecuting, described consultant psychiatrist Dr Seán Ó Domhnaill as “the cornerstone of the defence for diminished responsibility”.

He noted that the other defence psychiatrist said he was relying on Dr Ó Domhnaill’s diagnosis of Pervasive Developmental Disorder in Mr Locke.

“Dr Ó Domhnaill is wholly unreliable,” he said. “His lack of familiarly with the evidence is simply stunning.”

Mr Farrell suggested there must be a basic concern for his competence as a witness in such a case.

Case of insanity

“He has come to a series of outlandish conclusions that not even the defence are prepared to rely on,” he said.

“He says this is actually a case of insanity,” he said, adding that nobody else was “buying that”

The barrister said the defence had asked its psychiatrists to proceed on the presumption that Mr Locke’s account of what happened in the room was true.

Mr Locke said he had brought items to restrain Ms Blount so she would listen to him. He said she screamed when she saw them and that he panicked and strangled her.

“This is the foundation of this defence,” he said. “If something totally different, substantially more sinister, more deliberate happened in that room, then your deliberations may be very, very swift indeed.”

He said Mr Locke was capable of telling elaborate lies.

“I suggest the starting point for you is that Eric Locke would appear to be an absolutely inveterate liar,” he said.

He told the jury that the accused had thought through every step of his plan to meet her in the hotel room. He pointed to messages in which, posing as Shane Cully, he was ‘needling her’ to leave a keycard for him at reception.

“He has anticipated there very well may be a peephole in the door. He doesn’t want to run the risk of knocking on the door, and Sonia Blount looking out to see who it was,” he said. “You can be damn sure that if Sonia Blount had looked out that door and seen Eric Locke, she would not have opened that door.”


He described as ‘distasteful’ any suggestion that Ms Blount may have subconsciously wanted to see the accused.

He said that the accused was not a compulsive liar, who just lied for the hell of it. “Eric Locke is somebody who, in the words of Dr Bunn, is a purposeful liar,” he said, referring to a second defence psychiatrist.

“He lies for a reason,” he added. “Most fellas, if they’re looking for a reconciliation, might turn up with a bunch of flowers, not with a pellet gun and masking tape.

“Mr Locke, lucky guy, turns up and is very quickly engaged in kissing.”

He said it was “contemptible” for him to have said that he dressed the body to give Ms Blount dignity in death. This was a lie, he said.

“There’s only one reason to clothe the body,” he suggested. “If there’s a naked lady found dead in a hotel room, that’s quite different from a clothed lady found dead in a hotel room.”

He asked if there was one member of the jury, who thought their sex had been consensual, something that was “integral to his story”.

He said the evidence clearly showed that Eric Locke knew well that what he was doing was wrong, was well able to control himself and that there could not be any question of diminished responsibility.

Psychiatric diagnosis

“This is a man, who until the eve of a murder trial, did not have any psychiatric diagnosis. That should set off alarm bells to you,” he said. “I suggest this construct of diminished responsibility is little more than that.”

Patrick Gageby SC, defending, said the three psychiatrists who had given evidence were markedly different.

“It is not their function to decide the question of whether Eric Locke is truthful,” he told the jury. “You’re entitled to cherry pick.”

He said Dr Ó Domhnaill had appeared poorly prepared and not very good at court presentation, but said he did appear to have expertise in developmental issues. He said he hadn’t heard any evidence to the contrary, and was ‘not so sure’ that he was challenged on his diagnosis of PDD.

Mr Gageby said that the question of PDD stood up.

“Eric Locke has always been different since his teens,” he said.

“When they broke up, he went to pieces,” he continued. “He gave up his job.”

He outlined his suicide attempt and consequent treatment in hospital, as well as his dealings with Pieta House.

“What do these things say about his mental condition?” he asked.

He said that nearly all of this case went back 35 years, noting that his client had not been known to gardaí until arrested to prevent his suicide after the breakup with Ms Blount.


“That’s unusual. It’s also a bit unusual if you take the view that he has a personality disorder,” he said, referring to the diagnosis given by the State’s psychiatrist, which would not qualify for diminished responsibility.

“The totality of the evidence supports a mental disorder,” he said. “We’re not asking that you absolve him of responsibility; it’s a question of diminishing it substantially.”

He quoted another psychiatrist who used to suggest that juries in insanity cases would ask: “Was the illness in the driving seat?”

Mr Gageby suggested that the jury make some small adjustment to that analogy for diminished responsibility.

“If the accused is in the driving seat,” he began. “Was there a steer, which was deflecting to the extent that it diminishes substantially the responsibility?”

He told the jurors that this was for their consideration, not for one of the doctors.

“It’s not the function of psychiatrists to put a benign spin on one side or the other. They should stay out of the facts,” he said. “My respectful position to you is that there is, on the balance of probabilities, cause to find diminished responsibility.

Mr Justice Michael Moriarty will charge the jury on Monday.
