'Deranged monster' who claimed abused partner stabbed herself to death launches conviction appeal
Summary
Martin Hayes, aged 34, was convicted of manslaughter for the 2017 death of Amadea McDermott, aged 27, after a domestic‑violence relationship. He was found not guilty of murder by a majority verdict in the Central Criminal Court. Hayes admitted using violence against McDermott and was sentenced to 12 years and six months' imprisonment. He appealed, arguing that evidence from a subsequent partner, Niamh Higgins, was highly prejudicial. Higgins had testified that Hayes had helped her stab herself and that she feared he might be released on bail. Hayes' counsel claimed this evidence should have led to a jury discharge, while the prosecution contended it was irrelevant and outweighed by other evidence. The Court of Appeal will decide the appeal at a later date.
