Who Was Paddy O’Mahony? A Beloved Kerry Grandfather and Community Pillar
Patrick ‘Paddy’ O’Mahony was a much-loved 84-year-old grandfather, father, farmer, and former Army Reserves officer from Ballyreameen, near Castlemaine, Co Kerry. Known for his warmth, humor, loyalty, and storytelling, he was a registered firearms dealer with a passion for history and antiques.
He served in the FCA (now Army Reserve) from 1955, retiring as a Captain in 1994 with an exemplary record. Recently widowed after losing his wife to dementia in November 2023, Paddy was described by his granddaughter Grace as a protective figure who made everyone feel safe. His home was a place of laughter, stories, and love – until that fateful weekend visit from his old friend Thomas Carroll.
The community of Castlemaine remains in shock over the loss of such a respected figure in this quiet rural area of Mid Kerry.
The Fatal Weekend: From Friendship to Fatal Shooting
Thomas Carroll, a retired Defence Forces sergeant major with over 30 years of service including peacekeeping tours, had been friends with Paddy O’Mahony for decades. He visited O’Mahony’s home on the weekend of February 24, 2024. The first evening was pleasant, but tensions escalated the next day.
CCTV footage showed an argument, with Carroll locking O’Mahony out of his own house and throwing his walking sticks away – an act prosecution called “cruel.” The footage then captured the fatal shooting with a Beretta pistol. O’Mahony convulsed and fell, left lying outside in the cold for over 12 hours while Carroll retreated indoors without aiding him.
Initial reports suggested a fall, with no visible blood. Carroll called O’Mahony’s son, Paddy Junior, claiming his father had fallen. It was only during mortuary examination that a bullet wound was discovered – the projectile had traversed the liver and spleen, causing fatal haemorrhage, with no exit wound.

Grace O’Mahony’s Heartbreaking Victim Impact Statement: Family ‘Shattered’
In an emotional address at the Central Criminal Court, Grace O’Mahony, Paddy’s only granddaughter whom he affectionately called his “favourite,” detailed the devastating toll on the family.
Coming just three months after losing her grandmother, the murder left them unable to grieve properly. Grace spoke of constant intrusive thoughts, nightmares, anger, fear, sadness, and betrayal. She misses her “Gaga” terribly and finds small comfort imagining him reunited with her “Nan.”
“Our family was shattered… There has not been a single day that I have not thought about what happened to him.” The family seeks justice to begin remembering the joy rather than the pain of his horrific death.
Grace thanked the jury, judge, prosecution, and gardaí for their sensitivity throughout the process.
Judge’s Scathing Remarks and Life Sentence for Thomas Carroll
Mr Justice Patrick McGrath described Carroll’s actions as “abhorrent and appalling,” lacking human decency. He highlighted the cruelty of leaving his “dear long-time friend” outside overnight and then fabricating lies to exploit the family’s kindness.
The judge noted Carroll’s brief admission during garda interviews – calling it a “cold-blooded and vicious act” when shown CCTV – as the only truth he told. Rejecting intoxication as a defense, the jury found intent to murder.
Carroll accepted responsibility and expressed remorse through his counsel, but showed no visible reaction to the mandatory life sentence, backdated to his custody date.
