The man, whose identity is suppressed, said Lamarre-Condon arrived at his workplace on February 19, 2024, and told him he had 'killed someone'. When pressed, the accused allegedly said he shot the first victim 'through the head' and the second 'through the door', adding that the second person 'wasn't meant to be shot' but he 'couldn't leave any witnesses'. The friend said he was in shock and declined Lamarre-Condon's request to take the day off to help move the bodies.
The court heard that Lamarre-Condon later tried to pass off the confession as a joke, messaging the friend to ask whether he liked his 'Oscar performance' before telling him it was real and that he did not want him to tell anyone.
Earlier evidence focused on a trip to a national park in early 2024, where the accused allegedly test-fired his police-issue Glock pistol with bullets taken from police training sessions. He gave the friend a police-issued radio and asked him to listen for any reports of police movement. The friend described the sound as 'super loud' and said it echoed through the valley.
Lamarre-Condon, 31, has pleaded not guilty to two counts of murder and one charge of aggravated break and enter. He is accused of shooting dead Jesse Baird, 26, a former Network Ten producer and presenter, and Luke Davies, 29, a Qantas flight attendant, in Baird's Paddington home.
The Crown alleges Baird's murder was premeditated and that Lamarre-Condon shot Davies through a bedroom door to eliminate a witness. The defence claims both men died accidentally during a struggle and that Lamarre-Condon acted in self-defence, panicking and disposing of the bodies days later.
The trial before Justice Natalie Adams continues.
