Graphic photos shown in court during Beau Lamarre-Condon murder trial

Photographs of possessions, blood-stained bedding and clothing found in a skip bin have been shown to jurors in the trial of a former police officer charged with murdering a Sydney couple.

The 31-year-old, who has pleaded not guilty to two counts of murder, is accused of shooting the pair with his service pistol in the man's Paddington terrace, in Sydney's east, in February 2024.

His lawyers have indicated there will be a self defence argument.

The Supreme Court trial is now in its second week, and jurors are being shown a large collection of photographs taken by police at key locations including the man's Brown Street home.

The court has heard police went there after a ground keeper found items with red staining on them in a skip bin in Cronulla.

On Wednesday, jurors saw photographs of clothing and bedding, which was retrieved from inside black bin bags.

The blood-stained bedding included a quilt cover, fitted sheets and a pillowcase.

Police also collected and photographed a jumper, shorts, button-up shirt, and four white AFL goal umpire flags, all of which had blood staining on them, the court heard.

Testing confirmed matches for the DNA profiles of the man and his partner.

The jury was also shown photographs of a watch, wallet and identification and bank cards in the man's partner's name, also located in the skip bin.

Crime scene specialist gives evidence

Senior Sergeant Bronwyn Lansley, a specialist crime scene officer, has been in the witness box as jurors were shown dozens of photographs from the Cronulla bin and also the Brown Street terrace.

They have been provided with a floor plan of the property, with markers of items mentioned in the evidence.

The jury has been told a fired cartridge was located above a kitchen cabinet of the man's home.

The terrace had a sub-level beneath the bedroom and part of the hallway, which extended to underneath the kitchen.

In the photographs, investigators marked multiple areas of apparent bloodstains on a dismantled bed head and base, which DNA testing later matched to the man and his partner, the court heard.

The jury has been shown photographs of small areas of visible blood staining on the bedroom floor.

They have also been shown damage to the kitchen floor in an irregular shape — which Senior Sargeant Lansley said was consistent with a bullet hole — along with damage to a wall, and blood in the sub-floor level beneath, which testing suggested was from the man.

Alleged series of events

The prosecution alleges the defendant stalked the man in the lead-up to the deaths, following a brief romance in 2022 and parts of 2023, which the man regarded as more casual.

The Crown has said he developed an obsessive and jealous infatuation with the man, who was a television presenter and AFL umpire, and would monitor his relationships with other men and interfere with his phone and Instagram account.

The Crown's case is that the defendant allegedly shot the man twice in the kitchen.

He then allegedly shot the man's partner through a bedroom door as he tried to call Triple Zero (000), in order to eliminate him as a witness to the alleged murder.

The defendant is alleged to have immediately cleaned the property before unsuccessfully attempting to sink the men's bodies in a dam at Bungonia, south of Sydney.

They were ultimately found near a monastery in an area about 20 kilometres away.

The defence has flagged an alternative version of events, saying their client's case is that there were two separate struggles in the terrace with the man and then his partner, both involving the defendant's police pistol, which resulted in the two deaths.

The trial, before Justice Natalie Adams, has an estimated duration of three months.
