Man who beheaded wife to remain in Central Mental Hospital

A man convicted of killing his wife in Finglas, Dublin in 2021 has been returned to the Central Mental Hospital for continued treatment. Diego Costa Silva, aged 35, was found not guilty of murder by reason of insanity following his trial at the Central Criminal Court earlier this month. He had pleaded not guilty to the charge relating to the death of his wife on November 4, 2021 at their home in Charlestown Place. Evidence presented to the jury established that Mr Costa Silva was suffering from cannabis-induced psychosis at the time, causing him to believe his wife was possessed and posed a threat to him. Two forensic psychiatrists confirmed he met the criteria for a finding of insanity under the Criminal Law (Insanity) Act 2006. At today's hearing, Mr Justice Michael MacGrath ordered his return to the Central Mental Hospital, where a consultant psychiatrist confirmed he continues to require in-patient treatment. His case will be reviewed again on July 29.
