Julian Cuddihy, aged 43, was accused of murdering his mother Kathleen, aged 73, and father James, aged 77), at their home in Churchtown, Carndonagh, Co Donegal on October 22, 2014.
Earlier this month, he pleaded not guilty by reason of insanity and a jury delivered a unanimous not guilty verdict after less than an hour of deliberation at the Central Criminal Court.
Mr Cuddihy, who believed that by killing his parents he was sending them to heaven, was yesterday committed to the Central Mental Hospital (CMH) in Dundrum for inpatient care.
Ms Justice Margaret Heneghan ordered his committal on foot of a report by Dr Sally Lenihan, consultant forensic psychiatrist based at the CMH in Dublin.
Dr Lenihan told the court that Mr Cuddihy was first admitted to the CMH on October 31, 2014, suffering from psychotic symptoms and delusional beliefs.
She assessed him as suffering from paranoid schizophrenia, a state of mind that affects his thinking, perception, emotion, and judgement, and which impairs his mental function to the extent that he requires care or treatment.
She told the court that the kind of care Mr Cuddihy needs is available only at the CMH.
Ms Justice Heneghan said she was satisfied that Mr Cuddihy was suffering from a mental disorder under the definition of the 2006 Criminal Law (Insanity) Act and was in need of inpatient care in “the only designated centre” — the Central Mental Hospital, Dundrum.
The judge ordered his committal to the CMH for inpatient care and treatment.
