A 27-year-old Irish woman has told a Sydney court she tried to leave her fiancé multiple times over the course of their abusive relationship before she killed him in February 2017.
On Tuesday, Cathrina Ann Cahill, who has pleaded guilty to the manslaughter of David Walsh, faced the final day of her sentencing hearing in the New South Wales Supreme Court.
According to a set of agreed facts in the case, which Justice Peter Johnson described more than once as “unusual”, Cahill killed Walsh in the early hours of February 18, 2017, after he violently assaulted one of three friends Cahill had returned home with after a night out drinking.
She inflicted a fatal stab wound to his neck as the chaotic scene unfolded at the home she and Walsh shared in the south west Sydney suburb of Padstow.
The pair were both Irish nationals in Australia on working holiday visas.
