The murder trial of an Australind woman accused of stabbing and killing her boyfriend at their Leschenault Drive home in January began today.
Rachael Boyd, 29, has pleaded not guilty to the murder of Trent Panizza, 29, in the Supreme Court in Bunbury.
Prosecutors claim Ms Boyd intended to injure Mr Panizza during a heated argument at home on January 28, 2012.
But Ms Boyd claims she was only holding a 16cm butchers knife to ward off Mr Panizza - to warn him not to approach - when he lunged at her and came into contact with the knife, which then entered his heart.
Prosecutor Robert Wilson said the State accepted Ms Boyd did not intend to kill her de facto partner, but she must have known her actions would result in life threatening injuries, making her liable for murder.
Mr Wilson said in his opening address that the couple, who had a turbulent relationship, had been arguing bitterly that afternoon, before Mr Panizza was killed at 6pm.
“It was a heated argument in which fry pans and cat food were thrown, and it ended tragically for all when the knife entered the left chest, and into the heart, of the deceased,” he said.
The court was told Mr Panizza was heavily intoxicated and an argument over his drinking, and Ms Boyd’s desire to go and visit her parents, descended into violence.
Prosecutors say Ms Boyd admitted to throwing two fry pans at Mr Panizza, as well as cat food cans on the floor, before he pushed her to the ground in the kitchen.
Ms Boyd then grabbed a butcher’s knife from the sink and held it out in front of her, and said he "came at her".
The defence admits Mr Panizza died from a puncture wound to the heart, and that Ms Boyd had been holding the knife.
The court was told Ms Boyd was deeply distressed and rang ambulance officers immediately, and could be heard sobbing "don’t die sweetheart, I’m sorry".
Defence lawyer Linda Black says her client was holding the knife for protection and to dissuade him from coming closer, so did not intend to harm him.The trial is due to continue this week.
