Roscommon man who stabbed his mother to death found not guilty of murder by reason of insanity

A 29-year-old man from Roscommon has been found not guilty of murdering his mother by reason of insanity at the Central Criminal Court. Paul Henry was charged with killing Ann Henry at Abbeystown, Ballyphesan on 17 September 2011. The defence conceded that Henry killed his mother but argued he was legally insane at the time. Two psychiatrists gave evidence: the defence called a consultant psychiatrist who diagnosed a delusional disorder, whilst the prosecution's forensic psychiatrist diagnosed paranoid schizophrenia. Both experts testified that Henry lacked capacity to form criminal intent due to his mental condition. The jury deliberated for one hour and 36 minutes before returning a unanimous verdict of not guilty by reason of insanity. The judge ordered Henry's detention at the Central Mental Hospital and praised the jury for their careful consideration of the evidence.
