Summary

In the trial of Sean Murphy, 29, who stabbed his housemate Michael Olohan, 35, to death, the prosecution argues a not‑guilty‑by‑reason‑of‑insanity verdict, citing two psychiatrists who say Murphy was psychotic and unable to resist. The defence, however, maintains that Murphy has some criminal responsibility and should be found guilty of manslaughter due to diminished responsibility. Both sides agree Murphy suffered a severe mental illness, diagnosed as obsessive‑compulsive disorder with psychotic symptoms. The jury is instructed to consider whether Murphy's mental state negated all responsibility or merely reduced it. The case is set to be heard by a jury of twelve, with deliberations to begin the following day. The trial is ongoing and no verdict has yet been reached. Sean Murphy pleaded not guilty and was found not guilty by reason of insanity.
