A woman accused of the brutal stabbing murder of her ex-lover has changed her plea to guilty after a WA court heard devastating evidence of the victim's final moments.
WARNING: This story contains details some readers may find distressing.
Hannah Louise Glover, 30, and James Anthony Sorgiovanni, 29, have been on trial accused of murdering Tara Morrison in Busselton in April 2024.
The Supreme Court heard the trio were using drugs in Glover's Broadwater home before the killing.
Ms Morrison, 38, had previously been in a relationship with Glover, but had since begun a new relationship with Mr Sorgiovanni.
Her body was found in a wardrobe. She had suffered multiple stab wounds.
At the start of proceedings on Thursday, Glover rose to her feet and pleaded guilty to murder.
Glover's admission followed a day of evidence from a woman who was in prison with her, who testified that Glover had described in detail how Ms Morrison died.
The trial of Mr Sorgiovanni is continuing.
Victim dragged, stabbed in neck
The woman, whose name has been suppressed, told the court that Glover said four knives had been used, and how she stabbed Ms Morrison while Mr Sorgiovanni held her hands behind her back.
She said Glover had explained she was wearing a pink sarong or bandana across her face, and had grabbed Ms Morrison's hair.

Glover told the woman Ms Morrison had been dragged around the house during the assault, and described where blood landed in the home.
Glover said she stabbed Ms Morrison in the neck three times to make sure she was dead, then tried to burn down the home.
The woman told the court Glover did not reveal the total number of times Ms Morrison had been stabbed, nor explain how she was placed in the wardrobe.
Glover got 'high' from murder
The woman said Glover claimed she committed the murder because she had seen Ms Morrison give drugs to her young daughter, although the prosecutor earlier told the court there was no evidence this had occurred.
The court also heard Glover said Ms Morrison was obsessed with her and Mr Sorgiovanni was angry about this.
She said Glover showed "no remorse whatsoever" and even laughed about what she had done.
She told the court Glover claimed it gave her a "high" like she had never had.

Under questioning from Mr Sorgiovanni's lawyer, Lisa Boston, the woman admitted Glover had said "Jimmy" tried to pull her away, and at one point had grabbed her in a "bear hug".
The court was played several recordings of conversations between the woman and Glover, captured by a surveillance device placed in the woman's cell.
When the woman was asked why she told authorities about Glover's admissions, she said the details were "horrific" and that it was the right thing to do.
She said justice needed to be served.
