A seasoned police officer called to the bloody scene of an attempted robbery-turned alleged murder by samurai sword kept his junior staff away so they weren't exposed to the traumatic aftermath, a jury has heard.
Leading Senior Constable Elias Tsougranis recalled people everywhere when he was called to the Sydney inner west road on August 10, 2018, in the middle of the day.
After seeing the amount of blood coming from 30-year-old Jett McKee's head after it had just been sliced open, he "didn't think it was going to end well," he told the NSW Supreme Court on Tuesday.
Soon after he made orders to keep his junior staff away from the horrific scene.
"Don't need to expose them to that ... I've gone through this, they haven't," he said.
Hannah Quinn, 26, and Blake Davis, 31, have pleaded not guilty to murdering Mr McKee, while she has also denied a charge of being an accessory after the fact to murder.
After rendering aid to the man who had a pepper spray can in his pocket and blood pouring out of the "large gaping hole" in his head, Sen Const Tsougranis noticed no responses or pulse.
Mr McKee was declared dead shortly after paramedics arrived.
A female officer in attendance also observed a significant amount of blood loss causing her to turn to her two colleagues inside their vehicle and declare: "This is a very bad situation".
Constable Amanda Sillis saw brass knuckledusters, a black balaclava in a pool of blood and a blank-firing handgun nearby.
But her attention was quickly diverted to a group of people screaming and shouting at the end of the street where she ran over to find Mr McKee with a large open wound to his head.
After yelling out for a towel to stem the flow of blood, due to the nature of the wound she said she "didn't know what to do to help him".
The Crown has alleged Mr McKee who was high on the drug ice at the time planned to rob the couple who were thought to be drug dealers.
But shortly after Mr McKee burst into their home Quinn chased him down the street and allegedly tackled him, before Davis struck him with the sword.
Another sergeant who has previously given evidence on Tuesday recounted seeing "brain matter" and "skull fragment" along with black knuckledusters.
He then examined the contents of an Uber Eats bag the couple stashed in an alleyway before going on the run.
The delivery bag with "Hannah" written in blue on the front contained large amounts of cash, two mobile phones, medicine for Davis, multiple sets of nunchucks and an imitation gun.
After leaving in a hurry the couple's home was observed by police "flooded with empty food containers and dirty dishes," with old beer bottles strewn across a coffee table and an open can of baked beans containing a silver spoon.
Pink tracksuit pants with blood were also found at the end of the bed, while a black machete was located at the top of a cupboard.
The trial continues.
