After punching Mr Davis hard in the face with knuckledusters on, Mr McKee grabbed Ms Quinn’s bag and ran out of the couple’s granny flat.
The 23-year-old Tafe student and barista gave chase – “a remarkable thing, for a young woman who could be described as a waif”, Mr Hughes told the court – and caught up with Mr McKee.
Ms Quinn says when she grabbed her bag, Mr McKee tried to punch her and he fell over. Police will allege that Ms Quinn grabbed his jacket and flung him to the ground.
In hot pursuit, police facts say Mr Davis allegedly “inflicted a penetrating wound into the deceased’s skull using the samurai sword” he had grabbed from inside the home.
The sword penetrated three major bones in the skull, causing “major blood loss and death” in the aspiring rapper.
“What the f— have you done?” Ms Quinn screamed at her boyfriend.
Ms Quinn’s alleged next steps – climbing through a neighbour’s window to help her boyfriend, giving him first aid, changing clothes, booking a hotel room – led to her being charged on Thursday with a second offence, accessory to murder after the fact.
The couple spent the weekend in a number of hotel rooms across Sydney and in contact with various family members who advised them to hand themselves in, which they did on Monday evening.
Ms Quinn’s parents and brothers were in Newtown Local Court on Thursday when magistrate Margaret Quinn granted her conditional bail. Her mother openly sobbed as she saw her daughter on audio-visual link from Silverwater prison wearing prison greens and a scrunchie around her wrist.
As the court heard the facts, Ms Quinn also sobbed.
She will be set free on bail on the conditions that she reports daily to Redfern Police Station, surrenders her passport, makes no contact with Crown witnesses and is of good behaviour.
Her mother also lodged a $60,000 surety to the court.
Her solicitor Lauren MacDougall told Fairfax Media outside court that she and her client were thrilled with the result.
“She doesn’t belong in jail,” she said.
Ms Quinn and Mr Davis will both return to the same court in October.
