Husband who beheaded wife found not guilty of murder by reason of insanity

A man from Charlestown, County Mayo, has been found not guilty of murdering his wife by reason of insanity at the Central Criminal Court. The jury unanimously determined that Diego Costa Silva was suffering from cannabis-induced psychosis when he killed his wife, Fabiola De Campos Silva, at their home in Finglas, Dublin, on 4 November 2021. Two forensic psychiatrists gave evidence that Mr Silva's mental disorder caused him to believe his wife was possessed by a serpent and would kill him. Medical professionals had noted signs of psychosis after he was detained two days before the killing and recommended he remain as a voluntary patient, but he left hospital. Mr Silva was remanded to the Central Mental Hospital for assessment, with the case to return to court on 22 March for a psychiatric report on his current condition. The jury deliberated for two hours and 24 minutes before reaching their verdict.
