It is not known if it is an audio or video recording.
Jennifer Petelcyzc and Rowena Bombara were best friends, and Bombara mistakenly believed his estranged wife was staying at the Floreat home.
Gunman 'manipulative'
The court heard Rowena Bombara and her daughter Ariel had moved out of the family home in April 2024, just weeks before the murders, and had sought police assistance to move their belongings from the house.
When police arrived at the house, Bombara's son opened the door and appeared nervous, saying his father had "all the [gun] licences you can possibly imagine".
"I don't know if there are any firearms in [the safe] … there may be firearms in other locations," Issac Bombara is heard to say on the body-worn camera footage.
Constable Shaun King called for a second police car to attend and told the arriving officers to make sure they had "their plates in", referring to their protective vests.
But when he entered the house and met Bombara, he was the "opposite" of what he was expecting.
"I hate to say it, but he seemed like a nice man," Constable King told the court.

Bombara was accommodating, offering refreshments and allowing the officer to inspect his gun safe.
Constable King turned him down as he "did not want to escalate the situation" but admitted in hindsight he "should have" looked at the safe.
The coroner's court heard the conversation was an attempt by Bombara to "groom" the junior officers into thinking he was not a threat, despite his access to firearms.
"I believe it was manipulative … calculated … in an effort to place seeds of doubt in the attending officers' minds," said Superintendent Andrew Wilson, who reviewed the body-worn camera footage.
"In my opinion he was quite determined to find out what would happen to his guns … I believe he took the opportunity to try and manage that conversation."
Superintendent Wilson agreed this was common behaviour in a family violence situation.
He said police policy had changed since the Floreat murders.
Superintendent Andrew Wilson describes the gunman's demeanor as "manipulative" to officers.
Firearms are seized, and domestic violence perpetrators are removed from the home before family enter to retrieve their belongings.
