A man accused of murdering another man on the Central Coast took a trip to Sydney to buy drugs and returned to the dead man's home for a six-pack of beers on the day of the incident, a court has been told.
Giving evidence in a jury trial on Thursday, Yolanda Howlett said that her then partner Scott David Weaver had organised a lift to Sydney to buy two ounces of heroin after stabbing her and fatally stabbing his housemate.
"We got heroin. We wanted to get ice as well but mainly just we wanted heroin," Ms Howlett said under examination from crown prosecutor Brian Costello.
Weaver, 40, has pleaded not guilty to murdering 67-year-old Larry White, whose body was found at a North Gosford unit in December 2019.
He has pleaded guilty to manslaughter in the Supreme Court in Newcastle where his trial has been told the stabbing was allegedly done in self-defence.
Giving evidence about the events of the stabbing, which took place on November 20, 2019, Howlett said Weaver fatally attacked Mr White with a knife because of suspicions she was sleeping around.
Weaver also suspected Mr White of being a "f***ing dog" and lying about not having heroin in the house, Howlett told the jury.
She said she was stabbed in the abdomen on her birthday, November 20, because Mr Weaver was in a "very agitated state" and thought she had been unfaithful.
"Something just clicked. He went back to saying that I'd cheated and before I knew it, I turned around and I had a knife in my stomach," she said.
After accusing Mr White of wanting to "f*** [his] missus", the jury heard Weaver stabbed the 67-year old in the leg causing him to fatally bleed out on the floor.
"The blood was everywhere. It was in the carpet that much that it was going between my toes," Howlett said through sobs in the witness box.
She said she kept close to Weaver after that, going with him to exchange a necklace for a shot of heroin in Erina, returning to Mr White's house for beers and then driving to Sydney for more heroin, because he had threatened to "knock her" as the only witness.
"He said to me that he should knock me, I'm the only witness, and that I'm lucky that I'm his best friend."
Weaver's defence counsel has previously argued Howlett has since "turned against" Weaver in a bid to shift blame and protect herself.
The trial continues with Justice Stephen Campbell.
