"All of a sudden it had gone so quiet you could have heard a pin drop, it was that quiet," Madison Rake told the NSW Supreme Court in Orange on Wednesday.

In that moment of silence Ms Rake's then-boyfriend Richard "Ricky" Eggins was stabbed in the chest by Darryle Tailford who was holding a barbecue fork.

Within two minutes Mr Eggins died in the early hours of March 2, 2019, with the two-pronged utensil piercing his aorta.

Tailford, 28, has pleaded not guilty to murder and guilty to manslaughter, but the Crown has not accepted the latter plea.

Tailford fled in his car shortly after the confrontation and Ms Rake along with Michael and Renee Eggins found their sibling inside the hallway of an Orange home in central west NSW.

His chest was covered in blood and more was coming out of his nose and mouth.

One of the first police officers to arrive previously worked as a nurse and tried to revive Mr Eggins but he was pronounced dead by paramedics.

As the day unfolded Tailford visited various friends and messaged one saying: "I'm on da run bra got no one and nothing".

He also sent a text message to Mr Eggins' mother saying: "I dunno what to even think Wendy I'm so sorry".

"What do I do".

Wendy Eggins was at the time with police officers who instructed her to write that he should hand himself in, which he did that afternoon.

Madison Rake told the court how a birthday celebration for Michael Eggins began at Hotel Canobolas in Orange.

Tailford, complaining of a toothache, said he needed to consume more alcohol than the others, and downed about 10 rum and cokes.

The group left about 11pm for Ms Rake's home she shared with Mr Eggins and continued drinking.

In her police statement, she wrote that Tailford appeared "smashed" compared to the others as everybody suggested he might slow down his consumption.

"He was spilling his drink everywhere ... drinking all sorts of drinks, whatever he could get his hands on," she wrote.

At one point he asked to borrow Mr Eggins' shirt because he had vomited on his own and outside the home.

Tailford and his then-girlfriend Renee Eggins left for their home but were later followed by the others inviting them for dessert at McDonald's.

After arriving Ms Rake watched an agitated Tailford leave the living room and heard him kicking something around in his garage before trying to leave in his car.

His girlfriend pulled the roller door down daring him to drive over her, in a bid to get him out of his vehicle.

When the Eggins brothers tried to prevent Tailford driving, he entered the house and ran out holding the fork that Ms Eggins tried to grab off him.

Within a minute of Tailford walking back into the garage, Michael Eggins darted out leaving his brother inside.

The roller door prevented anyone from witnessing when the blade pierced through his ribs, by 60 millimetres on one side.

Tailford's defence has argued he did not intend to cause the brother of his then-girlfriend serious bodily injury, but the Crown submits he did and was capable of making decisions that evening despite being highly intoxicated.

The trial before Justice Stephen Rothman continues.
