Lamarre-Condon has pleaded not guilty to two counts of murder over the shooting deaths of Baird, 26, a former Network Ten producer and presenter, and Davies, 29, a Qantas flight attendant, on February 19, 2024. Their bodies were found in Bungonia, near Goulburn, in two layers of surfboard bags on February 27, 2024. Footage released by the court showed Lamarre-Condon buying a surfboard bag with a friend.
The friend, whose identity cannot be reported due to a court order, gave evidence on Monday about a series of recorded conversations in 2024 and 2025. In one call, on April 8, 2024, Lamarre-Condon said: "Make sure you don't talk to people about stuff, you know what I mean?" The friend replied: "I don't know what you're talking about, bro." Crown prosecutor Brett Hatfield, SC, put to the friend that he was "putting on a bit of a voice" in the call. "Sounds like it, yes," the friend replied. By that date the friend had provided statements to police, on February 23 and 24 and March 12.
The friend has given evidence that Lamarre-Condon bought a surfboard cover shortly before the alleged murders and later told him he had killed two people, with the second person killed to eliminate a witness. Lamarre-Condon said in the recorded conversations that he had never said this. "Don't you dare switch up," the friend replied. The accused suggested his friend was wrong in his recollection.
In a later call, on December 14, 2025, Lamarre-Condon told the friend to "bring your big boy diapers" before they were due to speak in person later that day. Asked what he believed the accused meant, the friend said: "We were going to have a conversation that might not make me feel too good."
During that face-to-face meeting, which was recorded, Lamarre-Condon said he had been suicidal from late 2023 because of trauma from work. He said this was why he took the friend on a drive to the Royal National Park in early 2024, where he used police training bullets to shoot his service pistol twice into bushland and asked the friend how loud the gunshots were. He said he planned to return to that location alone and take his own life. "If they think I'm a missing person, perfect," he said.
The recordings also captured Lamarre-Condon discussing the end of his casual relationship with Baird in November 2023, saying he was "upset like anyone is" but that it was "normal". He said he entered Baird's Paddington share house to "get my shit back" after the breakup and was "not doing anything wrong". The friend pressed him, asking: "How is it not break and enter?" Lamarre-Condon replied that Baird had a key cut for him, adding: "It's technically not. He gave consent. It actually doesn't meet the definition. It's trespass. Normal people do this on an everyday basis."
The friend told the court on Friday that Lamarre-Condon had been trying to buy a silencer in December 2023 or February 2024. In the recorded conversation, Lamarre-Condon said: "You cannot put a silencer on a police-issued f---ing firearm."
The Crown case is that Lamarre-Condon had his police-issued Glock pistol with him for a work shift on Sunday, February 18, the day before the alleged murders, and pretended to return it to a police gun safe at Balmain later that day. "He retained it despite having no authorised reason to do so," Hatfield said in his opening address to the jury. The Crown alleges Lamarre-Condon pretended to retrieve the pistol from Balmain on February 20 before returning the weapon, which was already in his possession, to Miranda police station, where he was based. The trial continues.
