Beau Lamarre-Condon rejects his feelings towards a love interest were unreciprocated, despite them cutting contact months before being fatally shot.

The 31-year-old has pleaded not guilty to murdering Jesse Baird and Luke Davies with his police-issue pistol at their inner-city Sydney terrace in February 2024.

On his sixth day of evidence in the NSW Supreme Court, the former senior constable denied liking Mr Baird more than the other man liked him.

“You were obsessed with him and he was fairly ambivalent,” crown prosecutor Brett Hatfield SC said.

“That is not the case,” Lamarre-Condon said.

“And your unrequited love turned into an obsession, didn’t it?” Hatfield asked.

“That is not the case,” the former officer repeated.

He was earlier questioned about seeing Instagram messages on Baird’s phone in November 2023.

These showed Mr Baird was dating another man named Damon Wilson.

Lamarre-Condon said he deleted messages while Mr Baird was in the shower as what he saw contradicted his belief the TV presenter was not dating Mr Wilson.

“Were you angry about this?” Hatfield said.

“Angry, no. Was I a bit kind of frustrated? … Yes,” Lamarre-Condon replied.
The 31-year-old admitted what he did was wrong.

But he told jurors he checked the messages and blocked Wilson because he did not want to help Baird cheat if he was in an exclusive relationship with someone else.

“It was based on your own sexual jealousy in relation to Mr Baird, wasn’t it?”  Hatfield asked.

“No,” the former police officer said.

Lamarre-Condon said he did not come out directly and ask Baird about the other man to avoid an argument.

“That would then be starting a fight. I didn’t want to fight with Jesse,” he said.

Lamarre-Condon admitted posting an image of flowers on Instagram six days earlier in a story only Wilson could see to falsely represent he was in a relationship with Baird.

He also posted a separate video of Baird on his bed playing with his dog to  Wilson and other close friends.

The posts were to weed out whether Wilson and Baird were in an exclusive relationship, the jury heard.

Wilson did not respond to the messages.

It was this flowers post that caused Baird to cut contact with Lamarre-Condon.

In a draft message sent to a friend after this, the then senior constable told Baird he had never lied or done anything crazy to him.

“Are you lying about not being a liar?” Hatfield asked.

“I have lied, yes,” the 31-year-old replied.

Lamarre-Condon dated Baird from December 2022 until they broke up in April the following year.

He insists they were romantically involved again between September and November 2023.

Baird and Davies were fatally shot in their Paddington home on February 19, 2024.

Prosecutors alleged Lamarre-Condon was obsessed with Baird despite the couple breaking up, staking out the other man’s house for hours before entering the home to murder him.

The 31-year-old claims he disguised himself as an Uber Eats driver to retrieve belongings from Baird’s home and has argued self-defence for the killings.

He says he accidentally shot Baird during a tussle in the kitchen and Davies shot himself during a separate altercation as he tried to leave the home to flag down an ambulance.

He led police to where their bodies were stuffed in surfboard bags and buried behind a rural monastery when he handed himself in days after the incident.
