Lamarre-Condon jury shown crime scene photos of bloodstains

The jury in the double murder trial of former police officer Beau Lamarre-Condon has been shown crime scene photographs of bloodstains found inside Jesse Baird's Sydney terrace.

Mr Lamarre-Condon has pleaded not guilty to murdering Mr Baird and his boyfriend Luke Davies by shooting them with his service pistol in Mr Baird's Paddington home in February 2024.

The Crown has alleged he developed an obsessive and jealous infatuation after a brief romance in 2022 and parts of 2023, and had stalked Mr Baird in the lead-up to the alleged murders.

The 31-year-old's defence team has flagged an argument of self-defence, saying there were two separate struggles in the Brown Street property involving his police pistol, which resulted in the two deaths.

The jury was on Tuesday taken through dozens of photographs from when expert forensic officers attended the property on February 22, 2024, several days after the alleged murders on February 19.

At the front of the property, police found a dismantled bed frame.

Jurors heard there were apparent bloodstains on the bed head and bed base, which was confirmed through testing. 

DNA results later suggested some stains contained a profile of Mr Baird, Mr Davies, or both of the young men.

Similar photographs were taken and testing conducted on small stains on the floorboard in Mr Baird's bedroom.

Crime scene officers used a chemical called Luminol — a liquid sprayed onto a surface, which is used as a presumptive screening tool for blood.

The chemical showed a blue glow in photographs to indicate the presence of blood not visible to the human eye, the court heard.

The jury was also shown photographs of the hallway of the terrace with a blue glow on the floor, and the same glow in areas of the bedroom.

Grounds keeper found bloodied items in skip bin

The court heard bloodied linen and possessions were found in a skip bin at a Cronulla Bowls Club after Mr Baird and Mr Davies went missing.

Their bodies were found in rural Bungonia, south of Sydney, in surfboard bags eight days after the alleged murders.

According to a grounds keeper at the Cronulla club, there were several plastic bin bags containing clothing inside the skip bin on February 20, 2024, when he realised someone had used it.

There were also AFL football shorts still in the packaging.

In his statement, which was read to the court, Craig Scott said he realised some clothing from the bags had red staining on it.

"It looked like dried blood to me," he wrote.

Mr Scott and a second worker also discovered a bedsheet with red stains, a silver watch and leather pouch, along with identification that belonged to Mr Davies.

He said they both thought something "suspicious" had occurred and reported the find to police.

The trial, before Justice Natalie Adams, is in its second week and has an estimated duration of three months.
