The text exchange was released by the NSW Supreme Court after it was shown to the jury in Lamarre-Condon's trial over the shooting deaths of Baird, a former Network Ten producer and presenter, and Qantas flight attendant Luke Davies.
Lamarre-Condon, 31, has pleaded not guilty to murdering Baird, 26, and Davies, 29, in Baird's Paddington share house with his police-issued Glock pistol on the morning of February 19, 2024.
At 5.56pm on February 19, hours after the alleged murders, a housemate – dubbed Belinda Smith in the proceedings – texted a photo of what she believed to be "rusted water" near surfboard bags and a tarpaulin in the courtyard of the home to another housemate. The second housemate, known as Sarah King in the case, replied: "What the actual f---?"
Smith told the court on Thursday that she inspected the backyard again the following day and "saw that the surfboards had been cleared, and the liquid was gone".
Texts between all three housemates, tendered in court, show a series of messages from Baird's phone the day after his death. The court has heard Smith and King had asked Baird to move out so that another female friend could join them in the terrace. He was slated to move out on February 20, the day after the alleged murders.
"Hi both!! I've hired an air tasker to come and collect my things … I might be doing a road trip to Perth with mates on Thursday night so should be flying back Sunday and will 100% have it out by then," a message from Baird's phone at 12.28pm on February 20 read.
Earlier in the trial, the defence argued Lamarre-Condon acted in self-defence. Defence counsel John Stratton SC told jurors the deaths were "a tragedy" but maintained his client did not murder either man. Stratton said Lamarre-Condon entered the Brown Street home on February 19 intending to recover belongings without meeting Baird, disguising himself with a motorcycle helmet. He said the two men struggled and the gun went off twice, fatally wounding Baird, before it was flung into another room.
Stratton said it was not disputed Lamarre-Condon did some "stupid things" including looking through Baird's phone, deleting contacts and deleting text messages. The Crown's case is that Lamarre-Condon, then a senior constable, disguised himself as an Uber Eats delivery driver, including with a helmet, when he entered the property, shot Baird twice in the kitchen, and then shot Davies who was in a bedroom calling Triple Zero.
The trial, before Justice Natalie Adams, is expected to run for three months.
