Blood stains, bone fragments and bullet revealed in Beau Lamarre-Condon murder trial

Hundreds of images from an inner-city sharehouse have been shown to a jury, as prosecutors piece together how Beau Lamarre-Condon allegedly murdered two men. Forensic evidence from the various crime scenes involved in the 31-year-old police officer’s alleged double murder has taken centre stage in the second week of the NSW Supreme Court trial.

Lamarre-Condon has pleaded not guilty to the murder of Jesse Baird, 26, and Luke Davies, 29, in the former’s Sydney terrace in February 2024. Images released by the court show how forensic investigators found dozens of blood stains in and under the Paddington house in the days after the killings.

Blood stains and bone fragments found among the men’s belongings dumped in a Cronulla skip bin were also shown to the jury on Wednesday. Crime scene officer Senior Sergeant Bronwyn Lansley explained to the 15-member jury how luminol, a chemical that highlights areas of possible blood staining, was used throughout the house.

The prosecution alleged Lamarre-Condon killed Baird “execution-style” in the kitchen, before shooting Davies through the bedroom door when he attempted to call triple-0. The officer spent hours in the coming days attempting to clean the scene before handing himself in, prosecutor Brett Hatfield SC said.

Lamarre-Condon says he killed the men in self-defence and they died from gunshot wounds during two separate violent struggles. While some evidence of blood was found on the floors and walls of the house, it was when investigators searched under the floorboards they made more notable discoveries.

A tarpaulin with a stain from pooled blood was found underneath the bedroom, Lansley said. There was also extensive staining on the underside of the floorboards and the joists supporting them, she said. “Blood flowed down a joist and saturated into the timber,” the crime scene officer told the jury. Under the kitchen, officers found a bullet that allegedly killed Baird, with impact damage and a small blood stain.

The bullet travelled through a source of blood before penetrating the wooden floor, Lansley told the jury. Body-worn video was played to the jury showing the moment detectives first arrived at the scene of the alleged murders. A trio of pre-arranged cleaners were in the house tidying up when investigators arrived, but were forced to leave to try and preserve the crime scene. Investigators discovered evidence of more bullet damage less than two months before the trial began during a final sweep of the house, the investigator said.

A stick-on plastic hook covered a repaired bullet hole in the bedroom door that wasn’t found until July, the jury heard. Receipts tendered earlier in the trial shed light on Lamarre-Condon’s cleaning of the Paddington house after the men’s deaths. Between February 19, the day the two men were killed, and February 23, Lamarre-Condon made 10 transactions at four Bunnings stores totalling $1448.71. A bucket and mop, disposable gloves, tape, cable ties, bleach and garbage bags were purchased by the officer in his first trip to the hardware store, four hours after he allegedly murdered the two men. Lamarre-Condon’s actions to clean the house did not show he intended to kill the two men, his barrister said in his opening statement.

“The conduct of the accused ... (was) not the actions of a man who believed he was guilty of murder, but a man who panicked considerably,” John Stratton SC said. Sporting goods were also part of the officer’s haul through three trips to Decathlon sporting stores. Lamarre-Condon bought a surfboard bag with a friend two days before the shootings, a purchase captured on CCTV and played to the jury. But the officer bought another surfboard bag in the hours after the two men died, an action prosecutors say indicates he was forced to adapt to the unplanned killing of Mr Davies. The trial continues.
