Summary

Patrick McDonagh, aged 52, is on trial for the murder of neighbour Peter McDonald, 73, on 25 July 2020. He pleaded not guilty to murder but guilty to manslaughter, a plea the State rejected. Consultant psychiatrist Dr Mary Davoren testified that McDonagh was not suffering a mental disorder at the time of the alleged offence; she attributed any abnormality to cannabis use. She described McDonagh as unreliable, noting inconsistencies in his accounts of drug use and memory. Davoren highlighted a history of substance misuse, including cannabis and benzodiazepines, and a refusal of a urinary drug screen four days after the incident. She also reported bizarre symptoms McDonagh claimed, such as seeing a bull and hearing voices, which she deemed atypical for schizophrenia. Professor Patricia Casey, called by the defence, argued that McDonagh's symptoms were reduced by acute schizophrenia. The trial continues before Mr Justice Michael MacGrath and a jury.
