John Carthy (9 October 1972 – 20 April 2000) was a 27-year-old Irish citizen with known psychiatric illnesses shot dead by the Garda Emergency Response Unit in controversial circumstances on 20 April 2000, after a twenty-five-hour siege at his home in Toneymore, Abbeylara, County Longford.
John Carthy was born the only son of John and Rose Carthy on 9 October 1972. He had one sister, Marie, who was two years his junior. He was an avid Handballer and member of Abbeylara Handball Club. His father, with whom he was very close, died on 12 April 1990. In 1992 John was diagnosed with clinical depression and, subsequently with bipolar affective disorder. John's general employment was in the construction industry. He resided with his mother in an old, three-bedroom house in Toneymore, Abbeylara. She and John were due to move from this old house to a new home which had been built on their land by Longford County Council as part of a rural housing scheme. The old house was due to be demolished. On 19 April 2000, the day prior to his death, John stayed in the family home all day with his mother. His mother's testimony to the Barr Tribunal indicated that John was very hostile to the move and that this was the primary topic of their discussions that day.
Like many people in the countryside, John Carthy was the legal owner of a double-barreled shotgun, in this case a Russian-made Baikal IJ-43M. He was also in possession of a licence in relation to this firearm. This license had been of limited duration prior to November, 1998 when it was changed to an unlimited type and this was subsequently renewed on 29 August 1999.
At approximately 15:40 on Wednesday 19 April 2000 John Carthy went to the cabinet within which was his shotgun. He brought it, a full box of cartridges and his gun belt back to the kitchen remonstrating, according to his mother, that "no one was going to put him out of his house". He loaded the gun with two cartridges, went outside the hall door and discharged two shots.
It is not quite clear whether John then forced his mother out of the family home, or whether she left at her own volition. However, Rose Carthy left the family home and travelled to her sister's home, two doors away. Mrs Carthy informed the Barr Tribunal that her son did not order her out of the home, despite rumours to the contrary at the time. She was, however, very afraid for her son. Rose Carthy asked her sister, Nancy Walsh, to ring the Gardaí in Granard, three kilometres away, to come out and "take the gun from John".
