latest first- Limerick man awaits sentencing for indecent assault of third victim Co. Limerick
Christopher O'Mahony (68), of Kerrykyle, Ardagh, County Limerick, sexually abused his daughter Emma O'Shaughnessy, now 42, from 1993 to 1996 when she was aged 10 to 13, and his sister-in-law Helen Costelloe, now 51, from 1983 to 1989 when she was aged between nine and 15. The abuse emerged after a family meeting on 4 July 2021 when Ms Costelloe disclosed it and Ms O'Shaughnessy said she had also been abused, and O'Mahony presented himself at Henry Street Garda Station with his wife three days later and admitted it. He pleaded guilty to 18 sample counts of sexual and indecent assault from 54 on the indictment and was jailed for nine years by Judge Sinead McMullan at Limerick Circuit Criminal Court on 20 March 2025, and placed on the sex offenders register. In November 2026, a third victim who contacted gardai after reading reports of the case came forward, and O'Mahony pleaded guilty at Limerick Circuit Criminal Court to two counts of indecently assaulting her on two dates in the 1970s when she was aged between five and 12, with sentencing due on 19 November 2026.
