Newly engaged woman pleads guilty to fiance's manslaughter

An Irish woman has pleaded guilty to the manslaughter of her fiance in their Sydney home after the charge was downgraded from murder.

The court heard Catherina Cahill, also known as Tina, was often abused and degraded by her partner David Walsh.

The couple had only been engaged for a month when their final fight ended as Cahill stabbed her fiance to death at their Padstow home in February last year.

Today was meant to be the start of a six-week murder trial, but a last minute deal saw the 27-year-old plead guilty to manslaughter.

The court heard Cahill and Mr Walsh had a “stormy relationship” and that the deceased had “abused and degraded” the accused with “provocative and controlling behaviour”.

Cahill’s attorney James Trevallion said both of the Irish nationals’ families had flown to Sydney for the trial.

“Her mother and dad are over here from Ireland. They have had a chance to talk to her in court today,” he told 7 News.

The story is making headlines around the world.

“Both of the individuals are from County Wexford so obviously it’s big story there for locals who would know both of the people involved,” Irish Daily Mirror Assistant Editor Aine Hegarty told 7 News.

“It’s been extremely difficult for both families,” she added.

Ms Cahill was arrested immediately after the stabbing almost two years ago and has been in custody ever since.

She will now be sentenced on the lesser charge of manslaughter next month.
