A former police officer is alleged to have become obsessed with one of his victims, leading to a double murder in Sydney, a court has heard. Beau Lamarre-Condon, 31, is on trial for two counts of murder and one of aggravated break and enter, and he has pleaded not guilty. He is accused of fatally shooting Jesse Baird, 26, and Baird's partner, Luke Davies, 29, at Baird’s home in Paddington in February 2024. Lamarre-Condon allegedly used his police service weapon during the attack. The trial began in Sydney’s Supreme Court, where he appeared in a light grey suit and repeated his plea of not guilty. He also offered to plead guilty to a lesser charge of manslaughter, but the prosecution rejected the offer. Prosecutors allege that Lamarre-Condon and Jesse Baird had a romantic relationship from late 2022 into 2023. Crown prosecutor Brett Hatfield told the jury that Lamarre-Condon developed an "infatuation and obsession" with Baird, which led to compulsive behavior. This behavior reportedly escalated after Baird ended all contact with Lamarre-Condon in November 2023. According to the prosecution, Lamarre-Condon began planning the murders in early 2024. He allegedly researched ways to muffle gunfire, rented a vehicle under his mother's name, and purchased a surfboard bag to help dispose of the bodies. Lamarre-Condon also retained his police weapon, even though he had no legitimate need to carry it, and disguised himself as an Uber Eats rider to gain access to Baird’s home. On 19 February 2024, Lamarre-Condon allegedly entered Baird’s home using a key he had previously obtained, wearing a motorcycle helmet and dressed as an Uber Eats rider. He shot Baird twice in the kitchen and then went to the bedroom, where he shot Luke Davies, the court heard. The bodies were discovered nearly 200 kilometers away in Bungonia eight days after the murders. Prosecutors said Lamarre-Condon had attempted to sink the bodies in a nearby dam but failed. The case has drawn widespread public and media attention, filling the courtroom with spectators. Baird and Davies’ family members, including their mothers and siblings, were also present. The jury has now been selected, and the trial is expected to last two to three more months. The court will continue to hear evidence and arguments as the case progresses.
