A 41-year-old man who strangled his brother to death with a bungee cord before hiding his body in a pit by the Cliffs of Moher has been found not guilty of his murder by reason of insanity.

Declan O'Cualáin, of An Caoran Beag, An Cheathrú Rua, Co Galway was charged with murdering Adrian Folan at Lislorkin North, Liscannor, Co Clare on 4 July 2014.

Mr O'Cualáin pleaded not guilty at the Central Criminal Court to murdering Mr Folan by reason of insanity.

Prosecution Counsel, Mr Anthony Sammon SC, had told the jury that the accused had become "fixated with paedophilia" and held the baseless delusion that his brother was a person "afflicted with this difficulty and he may have sexually abused a sibling".

Mr Sammon said the accused was in "an utterly delusional state of mind" at the time and the delusions were "not to be given any weight whatsoever".

Two consultant forensic psychiatrists gave evidence that Mr O'Cualáin should not be held responsible for his actions and he met the requirements for the special verdict of not guilty by reason of insanity.

After just 21 minutes deliberating, a jury of nine men and three women returned a verdict of not guilty by reason of insanity.

Mr Sammon SC told the court that a recommendation had been made that Mr O'Cualain be committed to the Central Mental Hospital and return to court in 14 days time.

Ms Justice Heneghan then made an order committing Mr O'Cualáin to go to the CMH today and be brought back before the court on 5 May.
