A former police officer accused of killing his former boyfriend and another man will try to prove he acted in self-defence.

Beau Lamarre-Condon, 31, appeared before the Supreme Court in Sydney on Tuesday for the second day of his trial for the alleged double murder of Jesse Baird, 26, and Luke Davies, 29, in their Paddington home in February 2024.

After the Crown laid out its case to the 15-member jury, Lamarre-Condon’s barrister John Stratton told the court how the defence intends to argue what happened.

Stratton said the deaths of Baird and Davies was “of any view a tragedy” and that the defence wouldn’t contend submissions from witnesses about his client and Baird previously being in a relationship.

He added that the pair broke up once in April 2023 and got back together briefly before splitting for the final time in November.

“(Lamarre-Condon) was very upset by the second breakup ... (and) thought Baird had not been honest with him,” Stratton said.

But he refuted the Crown’s version of events, which alleges Lamarre had a months-long obsession with Baird in the lead-up to the fatal night.

Defence lays out version of events

Stratton told the jury his client had travelled to the Paddington home in order to recover personal items and waited for a moment he believed no one was inside in order to avoid the “embarrassment” of an interaction with Baird.

Lamarre-Condon wore an Uber Eats outfit with a motorcycle helmet only to “masquerade as a delivery person if someone was to open the door” — not to avoid being identified by other potential witnesses as the Crown argued — according to Stratton.

According to the defence, the accused then walked through the front door of the home with his police-issued pistol as he was trained not to leave the weapon behind in a vehicle.

But when he entered the home he was confronted by Baird, who could not recognise him because of the disguise, and a struggle broke out between the pair.

The defence claims Baird was wielding a knife at the time and two shots were fired during the struggle, killing the 26-year-old before the gun flew into the living room.

Stratton said his client called triple-0 soon after but was interrupted by Davies, who had picked up the gun. Another struggle occurred which ended in Davies shooting himself dead.

‘The actions of a man who panicked’

Stratton argued Lamarre-Condon had no intention of causing harm when entering the home and that his client solely acted in self-defence.

The alleged cover-up, including cleaning of the crime scene and dumping of the two bodies in the days following, was due to Lamarre-Condon panicking as he was an active police officer and the incident “looked bad”, according to the defence.

“The conduct of the accused was not the actions of a man that was guilty of murder, but the actions of a man who panicked considerably and knew how the (alleged) crime may have been perceived,” Stratton said.

Lamarre-Condon’s alleged admission hours after shootings

The defence’s opening statement to the jury followed the Crown laying out its own case on Monday, which will include an alleged confession soon after the deaths of Baird and Davies.

Prosecuting barrister Brett Hatfield told the court that in the hours after killing the couple, Lamarre-Condon met a friend at his work after saying he was “in a bit of trouble but couldn’t speak in the home”.

Hatfield said the witness is expected to detail the meeting, which allegedly included Lamarre-Condon admitting to killing two people.

Lamarre-Condon allegedly told the witness he had killed the pair with a gun, made a gun gesture with his hand and said “pew pew”.

When asked if he was joking, Lamarre-Condon allegedly told the witness “I wish I was”.

The witness also claims to have been told by Lamarre-Condon he had waited for housemates to leave before entering the home and shot the first person in the head.

According to the Crown, Lamarre-Condon then heard scuttling near the front of the home and overheard someone trying to call police, shooting that person dead through a door.

The witness then claimed Lamarre-Condon killed the second person because he couldn’t “take the risk” and leave “no witnesses”.

It will also be alleged he called the witness later that night, claiming he had made up the story as a joke and said he “should get an Oscar”.

CCTV of alleged gunshots played to jury

The court watched CCTV footage from a neighbouring home at the time of the deaths of Baird and Davies, which the Crown will argue features three distinct gunshots within one minute.

Hatfield said the Crown will argue the first two gunshots, separated by just four seconds, were from Lamarre-Condon shooting Baird once in the neck before firing a fatal shot to the head execution-style.

A call to triple-0 was made from from Davies’ phone in the 51 seconds between the second and third shot, the Crown will argue.

The Crown will suggest the muffled phone call features Davies saying “get out .... f*** off” before a gunshot.

Hatfield said evidence will show Davies was fatally shot in the head through a door.

The Crown says Lamarre-Condon alleged planning stretched back weeks. He allegedly tested ways to muffle gunfire by firing shots through a paper bag in a park with a friend. He’s also accused of researching how to hide mobile phone records.

The Crown said the killings were the culmination of months of alleged stalking by Lamarre-Condon after he and Baird broke up.

“The accused’s infatuation and obsessive conduct continued and tragically escalated,” the court heard.

Lamarre-Condon is alleged to have slashed Baird’s tyres, broken into his home, stolen his wallet and phone, and even falsely claimed to have cancer.

At one point, he’s accused of sending Baird a text message: “You pull at people’s heart strings and expect no repercussions.”

The trial, where Lamarre-Condon has pleaded not guilty, is expected to last 12 weeks.
