Irish woman Tina Cahill to be sentenced for killing fiance

Newly engaged Cathrina Cahill, who fatally stabbed her fiance in Sydney in 2017, is due to be sentenced for his manslaughter today.

An Irish woman who fatally stabbed her fiance in Sydney is due to be sentenced for his manslaughter.

Cathrina “Tina” Cahill, 27, pleaded guilty to the manslaughter of David Walsh, 29, who she stabbed once in the neck in the early hours of February 18, 2017, at the Padstow home they shared with two other Irish nationals.

Her plea was based on substantial impairment due to an abnormality of the mind. The fatal attack occurred when an intoxicated Mr Walsh launched an unprovoked attack on a man invited into the home by Cahill and the two other female housemates.

David Walsh and Tina Cahill became engaged five weeks before his death.

Cahill, who had also been drinking, was punched by her fiance when trying to stop the attack, before she took out a “large, very sharp, bladed knife” from the cutlery drawer and stabbed him.

At the time, she was on a good behaviour bond and the subject of an apprehended violence order issued to protect Mr Walsh, after she was convicted of recklessly wounding him with a glass candle holder in 2015.

Cahill gave evidence at her sentence hearing about Mr Walsh’s repeated violence, including punching strangers and biting her all over her body, his accusations of her sleeping with other men and his deleting texts from her phone.
