Beau Lamarre-Condon accused of faking cancer diagnosis to manipulate friend before alleged murders

Beau Lamarre-Condon “guilt-tripped” a friend into helping him fake a cancer diagnosis in the hope of explaining his erratic behaviour, months before the police officer allegedly murdered Jesse Baird and Luke Davies, a Sydney court has heard.

Beau Lamarre-Condon has been accused of fatally shooting Baird, 26, and his partner, Davies, 29, with a police service weapon in Baird’s Paddington home on 19 February 2024.

The 31-year-old has pleaded not guilty to two counts of murder and one charge of aggravated break and enter.

A close friend of Lamarre-Condon told the NSW supreme court on Friday that the policeman had become “infatuated” with Baird during a brief relationship.

Baird ended the relationship in November 2023 after the accused went through his phone and deleted messages from other men, which made Lamarre-Condon “really upset”, Shae Davison told the jury.

Lamarre-Condon then asked to stay at her house because he did not want to be alone, Davison said.

The police officer arrived at her home with a backpack the next day and asked to send a message from her Instagram to Baird as “one last try to win Jesse back”, she told the court.

But Lamarre-Condon did not want her to read the message, claiming there were medical details he did not want her to know.

She didn’t want to do it initially but said: “He put a lot of pressure on me, he said he never asked anything of me, he’s so upset, can I help.”

“He wore me down,” Davison said on Friday. “It felt like guilt-tripping to me and using my friendship to get what he wanted.”

She agreed, on the condition Lamarre-Condon read out the text to her, while leaving out the medical details.

When he read out the message, she asked him to delete parts that weren’t true, and it looked like he was typing and actioning her edits, she told the court.

He then sent the note in a series of messages, and told her she was allowed to read it after 4 December 2023, when he told her he was set to undergo surgery. He left her home about an hour after he arrived.

The 1,600-word Instagram note claimed Davison had gone to Westmead hospital with Lamarre-Condon.

“He was told he had a cancerous tumour growing in his left shoulder joint/ligament area,” the text read out in court stated.

“Worst-case scenario, it could result in … possibly having his arm amputated.

“He was then immediately subscribed [sic] numerous medications … everyone knows these medications are some of the strongest you can be subscribed, which throw off your hormones massively, which throws off how a person can act in their day to day life.”

The friend told the jury she had not attended the hospital with Lamarre-Condon, nor did he clear this part of the text with her.

The messages tried to justify the officer going through Baird’s phone and stated “this is very out of character for him”.

“There is real love there, trust can be built back on that,” the note purportedly from Davison stated. “Even if you guys never hang out again, I know Beau wants to make things right.”

The friend was unsure if Baird read the messages but said it was possible he had seen them through Instagram’s preview function. Lamarre-Condon later asked her to unsend the messages.

She obliged and tried to ask him about the content of the messages but he did not want to talk about them.

“He was quite annoyed, I could tell in his voice he was frustrated that I had [read them],” she said.

It’s alleged Lamarre-Condon began planning to murder Baird in early 2024.

The defence team has claimed the police officer was acting in self-defence after he disguised himself as an Uber Eats driver and entered Baird’s home on the day of the shootings.

The trial before justice Natalie Adams continues.
