It's alleged Adam Azzi used the stainless steel steak knife, shown by Detective Senior Constable Darryl Glynn to a jury in Wagga on Tuesday, to kill Lloyd Kennedy.

The item was found by Neptune Drive resident Jayne Bullock in her yard a day after the alleged incident on Webb Street.

The court had previously heard Azzi was armed with the knife and a table leg on November 6, 2016, outside his ex-partner's Webb Street home.

He has pleaded not guilty to murdering Mr Kennedy and threatening his friend, Nathan Vercoe.

The table leg, which the court heard was found on the road, and a brown table top which Mr Vercoe said he had armed himself with, were also shown to jurors.

The exhibits were later sent to the jury room.

The court heard a doctor certified Mr Kennedy was "life extinct" at Albury hospital at 9.37pm on the night.

A crime scene was set up in an Albury hospital surgical room after Mr Kennedy died to preserve evidence.

Detective Senior Constable Darryl Glynn said the scene of the alleged murder was chaotic after the incident.

Sergeant Stephen Bosch said he had viewed Mr Kennedy's body.

He said Mr Kennedy's partner, Sianne Mather and brother, Brendan, expressed a desire to go in and identify the body.

Detective Senior Constable Glynn said he also attended the hospital while Mr Kennedy was in surgery before going to the crime scene.

"Essentially the place was in chaos," he said of arriving outside the home.

He spoke to Mr Vercoe and said he was identified as a witness rather than a suspect.

The detective agreed that Mr Vercoe told him "someone named Adam or 'Abo' was responsible" for Mr Kennedy's death.

DNA was taken from the late man, Azzi, and Azzi's former partner Lisa Restall, but not Mr Vercoe.

"Nathan Vercoe was never considered a suspect," the detective said.

Senior Constable Justin Dickson said in a statement a man he knew as Nathan was "in a hysterical state" at the scene.

Jurors had previously been shown a video walk through involving Mr Vercoe and police at the Webb Street home the day after the incident.

Mr Vercoe could be seen picking up the timber table top next to a front door and showing his alleged interactions with Azzi outside the home.

The court heard that because it was picked up by Mr Vercoe, it was impossible to tell if his DNA was on it before or after the walk through.

Police conducted a search of nearby Lavington East Primary School after the incident but didn't find any evidence.

The court heard Azzi was arrested somewhere in the Albury CBD the day after the alleged murder.

Detective Senior Constable Glynn said allegations were put to Azzi during an interview but he exercised his right to silence.
