Psychiatrist tells murder trial accused was unable to refrain from killing

At the Central Criminal Court, a defence psychiatrist has testified that a man charged with murdering an elderly patient at Cavan General Hospital was unable to refrain from killing due to the withdrawal of anti-psychotic medication. Ian Harman, aged fifty, from Carrigallen in County Cavan, has pleaded not guilty to the murder of Michael Treanor at the psychiatric unit on 27 June 2011. Consultant psychiatrist Dr Bob Johnson told the court that Mr Harman's olanzapine medication was discontinued upon admission, causing akathisia, a distressing condition characterised by severe restlessness. Dr Johnson stated that Mr Harman's responsibility for the killing was not merely diminished but destroyed. A clinical pharmacologist also gave evidence for the defence, asserting that Mr Harman should not have been prescribed the medication in the first place. The prosecution challenged these assertions during cross-examination. The trial before Mr Justice Garrett Sheehan continues.
