Eoghan O’Mahoney, aged 34, of Craigford Drive, Killester, was found not guilty yesterday of the attempted murder of his grandmother Catherine McGillion, now aged 91, on December 19, 2013, by reason of insanity.
The jury took 30 minutes to reach their decision, having been told by Pat McGrath, prosecuting, that the plea of insanity is not contested.
Mr McGrath read a statement made by the woman in which she described the close relationship she had with her grandson and insisted the attack was totally out of character.
She said she is proud of Eoghan, that he is the cleverest of her grandchildren, and had always been good at school. She was aware that he had some mental health issues but said he had always been good and kind to her.
She said they had grown even closer when her daughter, his mother, died.
On the day of the alleged attack, she was preparing lunch for the two of them, as was their daily routine.
When Mr O’Mahoney arrived, he took a knife and grabbed her hand.
“He kicked me four or five times,” she said. “He cut the left side of my neck. There was blood everywhere.”
The attack continued until Mr O’Mahoney’s brother Conor arrived.
Sean Gillane, defending, told the jury: “What you see here is the horror of mental illness, and you have heard and seen here that this is a family built on love and mutual respect for each other.”
Mr O’Mahoney will return to court for further assessment on November 16.
