His lodger Mr Bellante was arrested at the scene and was later charged.
He was brought before Blanchardstown DC on Monday morning. The court heard he replied: "I am guilty" when the charge was first put to him.
He told Judge David McHugh he did not need a lawyer because he wanted to represent himself.
Judge McHugh ordered for him to be medically assessed while in custody. He was later admitted to the Central Mental Hospital for treatment.
Mr Bellante, who is originally from Palermo in Sicily, is due before Cloverhill District Court this morning.
