Summary

Diego Costa Silva, 35, pleaded not guilty to the murder of his wife, Fabiola Camara De Campos Silva, 33, at their home in Charlestown Place, Finglas, Dublin 11, on November 4, 2021. The Central Criminal Court heard evidence from two consultant psychiatrists who agreed that Mr Costa Silva suffered from a cannabis-induced psychotic disorder, a mental disorder under the Criminal Law (Insanity) Act 2006. They testified that he believed his wife was possessed by a serpent and that he had to decapitate her to ensure the serpent was dead. Both experts stated that due to this disorder, Mr Costa Silva did not understand the nature and quality of his actions or that they were wrong. Prosecution and defence counsel both submitted that the evidence supports a finding of not guilty by reason of insanity. Mr Justice Michael MacGrath has begun charging the jury, who will consider their verdict tomorrow. The matter is at the sentencing stage following the validated procedural stage, though the final verdict is pending.
