Senior Sergeant Bronwyn Lansley, a specialist crime scene officer, began giving evidence on Tuesday as prosecutors continued building their case against Lamarre-Condon, 31, who has pleaded not guilty to two counts of murder.
The jury was told a fired cartridge case was located above the kitchen cupboards of Mr Baird's Brown Street home, and that a bullet was found on the subfloor beneath the kitchen. Investigators also identified impact damage to a kitchen wall consistent with a bullet hole, and blood in the sub-floor level below which testing suggested was from Mr Baird.
Photographs shown to the court depicted blood-stained bedding, including a quilt cover, fitted sheets and a pillowcase, along with a jumper, shorts, button-up shirt and four white AFL goal umpire flags, all retrieved from black bin bags found in a skip bin in Cronulla. DNA testing confirmed matches to the profiles of both Mr Baird and Mr Davies. A watch, wallet, and identification and bank cards in Mr Davies's name were also located in the bin.
Lamarre-Condon, a former NSW police officer, is accused of shooting the couple with his service pistol at Mr Baird's terrace on February 19, 2024. The prosecution alleges he developed an "obsessive and jealous infatuation" with Mr Baird, a former Network Ten producer and presenter, after their casual relationship ended in November 2023. His lawyers have indicated there will be a self-defence argument.
