The jury in the murder trial of Saverio Bellante has heard he stopped taking antipsychotic drugs three days before killing Tom O’Gorman.
Thirty-six-year-old Mr Bellante has admitted killing his landlord on the night of January 11 last year.
The jury has been told that the only question they have to consider is whether insanity was a factor.
This afternoon the murder trial heard evidence from consultant forensic psychiatrist Dr Steven Monks.
He examined Mr Bellante when he was admitted to the Central Mental Hospital shortly after killing Tom O'Gorman (pictured) at the house they shared in Castleknock in Dublin in January of last year.
Dr Monks said Mr Bellante had suffered from mental problems in his early 20s and had been reducing the dosage of his medication under supervision, until he stopped taking it on January 9.
Dr Monks said Mr Bellante started to feel unwell on January 10, and started to interpret things as good and evil.
On the night Mr O’Gorman was stabbed, January 11, Mr Bellante said Mr O’Gorman started thinking like the devil, or was the devil.
Mr Bellante admits stabbing Mr O’Gorman and hitting him with a dumbbell, after which he ate part of what he thought was his heart.
