Luke Davies’ DNA was found on the trigger and handle of Beau Lamarre-Condon’s Glock pistol, the court heard.
Police forensic expert Senior Sergeant Bridey Allan told the court she examined and swabbed the gun for fingerprints and traces of biological material.
She swabbed the gun handle and found Davies’ DNA.
Davies’ and Lamarre-Condon’s DNA was found on the trigger, while Davies’ and Jesse Baird’s DNA was found on the muzzle.
Lamarre-Condon’s lawyers previously told the court that Davies grabbed the gun and accidentally shot himself.
Prosecutors allege Lamarre-Condon shot Davies in the head through a door.
The court also heard Lamarre-Condon allegedly drove the bodies of Baird and Davies to Bungonia with a female friend, who bought him an angle grinder from Bunnings on the way.
Senior Sergeant Christine Abela told the court that Lamarre-Condon’s friend, known by the pseudonym Elizabeth Kennedy for legal reasons, walked into Bondi Police Station with a lawyer on February 21, 2024.
Ms Kennedy gave police information on two missing people, Baird and Davies, under the agreement that she would not face criminal charges herself, Ms Abela told the court.
Police were told that Ms Kennedy had driven to the Goulburn area with Lamarre-Condon in a white van that did not belong to him.
They stopped at Bunnings, where she bought him an angle grinder, before driving to a property in nearby Bungonia.
Lamarre-Condon allegedly used the angle grinder to break the padlock on a property and put it in the letterbox.
Ms Abela told the court she went to Bungonia with police over a number of days until they eventually found a property resembling the one Ms Kennedy described.
Ms Abela then broke down while recalling the moment she realised Baird and Davies’ bodies were nearby.
‘As soon as I got out of the car, there was a strong smell,’ she said.
Ms Abela told the court through tears that she recognised it as the smell of a decomposing body.
The smell was stronger as she approached the fence.
She then saw two silver and blue surfboard bags stacked on top of each other, covered with branches and stones.
Baird’s body was allegedly shoved inside three bags – a black garbage bag and two surfboard bags, the court heard.
Jurors were shown distressing images of the surfboard bags containing the bodies of Baird and his boyfriend Luke Davies.
Beau Lamarre-Condon allegedly tried to hide the body bags at a rural property in Bungonia under rocks, tree branches and foliage, but photos showed the blue bags were clearly visible underneath.
Lamarre-Condon allegedly stacked one body on top of the other.
