A Sydney court has been told that former police officer Beau Lamarre-Condon was "homicidal, not suicidal" and manipulated allegations of workplace bullying to garner sympathy following a double homicide.

Lamarre-Condon has entered pleas of not guilty to charges accusing him of killing Jesse Baird and Luke Davies at a residence in the suburb of Paddington on February 19, 2024. Prosecutors allege the accused utilized his issued firearm to commit the killings.

More details are expected to emerge as the legal proceedings continue to develop.
