Martin Hayes was jailed for 12-and-a-half years for manslaughter at the Central Criminal Court, reported on 28 November 2023. The offence took place at Amadea McDermott’s home in Coolock in July 2017.

Mr Justice Paul McDermott said Hayes had shown no remorse and described his conduct as violent in language and action. The judge also said Hayes had tracked McDermott’s phone and held an unfounded belief that she was in a relationship.

Hayes had been found not guilty of murder but convicted of manslaughter by a jury earlier that month. The judge rejected a defence submission that the verdict could have been consistent with an accidental killing.
