A father-of-six who admits killing but denies Murdering his friend when he opened fire on him with a submachine gun in his front garden was suffering from substance-induced Psychotic disorder which would have diminished his capacity to control himself, a psychiatrist told his trial today. Consultant psychiatrist Dr John Hillery said the accused told him he was “shovelling big shovels of shit up his nose” at the time of the offence. Dr Hillery disagreed with forensic Psychiatrist Dr James Walsh, who told the trial that the accused was not suffering from a mental disorder and instead met the Criteria for Cocaine intoxication.
