Accused double murderer Beau Lamarre-Condon told a friend he broke in Jesse Baird's home on two occasions, a court has heard. 

The witness alleged Mr Lamarre-Condon altered Mr Baird's social media settings on his phone so he could track him.

The jury heard Mr Lamarre-Condon also took photos of Mr Baird sleeping with another man while he watched through a window. 

Former police officer Beau Lamarre-Condon told a friend he had broken into Jesse Baird's Sydney home twice and altered social media settings in his phone, tracked his location through Snapchat, and photographed him with another man through a bedroom window, a court has heard.

The 31-year-old ex-police officer has pleaded not guilty to murdering Mr Baird and Luke Davies and is on trial in the NSW Supreme Court.

He is accused of shooting the couple with his police pistol in Mr Baird's Paddington home on February 19, 2024, before attempting to dispose of their bodies in rural Bungonia, south of Sydney.

The Crown's case is that Mr Lamarre-Condon developed a jealous infatuation with Mr Baird, who ended their brief, at-times casual connection in November 2023, and that he had stalked him in the lead-up to the alleged murders.

The jury has heard allegations the accused initially attempted to sink the men's bodies in a farm's dam using quick-set cement and weights, but they were ultimately found in surfboard bags near a monastery in the area, eight days after the alleged murders.

A former friend of the accused, who is known by the pseudonym Elizabeth Kennedy at the trial, recalled on Tuesday how they reconnected sometime after 2019.

She said the defendant asked her to download the encrypted app Signal because it was safer for a police officer to use, but when his communications were about him "chasing a celebrity", she would receive photographs as iMessages.

The witness said she first heard Mr Lamarre-Condon mention Mr Baird in early 2023 and remembered the defendant sending her photographs of Mr Baird's work on television as a Channel 10 presenter.

"He started to tell me he's the one, and he became infatuated with him," Ms Kennedy said.

She told the court about a conversation she had with the accused on her balcony, after an initial split in 2023 between Mr Baird and the accused.

She claimed Mr Lamarre-Condon appeared "excited" and "happy" when he told her he had broken into Mr Baird's home after seeing where Mr Baird left a spare key and getting it cut.

Ms Kennedy said the accused told her he had gone into Mr Baird's home while he was asleep, taken his phone, and walked across the street.

She testified that he told her he had deleted contacts and alarms, deleted photos with other men, turned the location services on for Snapchat, and returned the phone.

Ms Kennedy told jurors that the accused appeared "very bubbly… very happy with himself" during the conversation.

She said that he had "unmuted" his own Instagram stories on Mr Baird's account so Mr Baird would see posts during an upcoming Europe trip the defendant had planned.

Ms Kennedy said after that trip, Mr Baird continued to come up in conversations — in person, on the phone and on Signal.

She told the court Mr Lamarre-Condon was trying to "bump into" Mr Baird.

"He knew what supermarket he would go to and what time …He'd know what time he'd leave the gym," she said.

Ms Kennedy gave evidence that the defendant told her about a second alleged break in at Mr Baird's home, during which Mr Baird had woken up when a phone charging cord was dropped.

The court has previously heard that Mr Baird chased an intruder out of the home during a break in that occurred in August 2023. 

Mr Lamarre-Condon has pleaded not guilty to a charge of aggravated break and enter.

Ms Kennedy said today: "The accused grabbed his wallet to make it look like it was a robbery."

She also recalled another time where she had received Signal messages about Mr Lamarre-Condon going to Mr Baird's home.

"He would take photos through the window of Jesse having intercourse with another man. So he didn't go into the house, but he was creeping out the front window," she said.

Ms Kennedy said Mr Lamarre-Condon had also told her he set up fake profiles of Mr Baird on the dating apps Tinder and Grindr.

She testified that on one occasion, he directed a man from Grindr to Mr Baird's home.

"Did the accused explain how he knew the man went to Jesse's house" Crown Prosecutor Caitlin Diggin asked.

She told the jury that in the early part of 2023, before the first split, based on what she saw on the defendant's Instagram account, it appeared to her the two were an "official" couple, but she said Mr Lamarre-Condon was worried about Mr Baird seeing other people.

Their dates included going to a lighthouse, the Figure 8 pools and concerts, the court heard, and Ms Kennedy claimed that Mr Lamarre-Condon would "use" his pet French bulldog named Ivy during their involvement.

"He would sort of use Ivy against him, because he knew Jesse really liked Ivy, so he would sort of tempt him with the dog."

Mr Lamarre-Condon's lawyers have indicated they will argue self-defence.

The defence case is that Mr Baird and Mr Davies died during separate struggles involving the pistol, jurors heard in the first week of the trial.

The Crown's case is that Mr Baird was shot twice in the kitchen before Mr Davies was shot through the bedroom door as he was trying to call Triple Zero (000).

A suspected bullet hole was belatedly discovered in the bedroom door in July this year, after it was previously covered by a stick-on hook and felt pad.

The court on Tuesday released a video showing a test shot from Mr Lamarre-Condon's pistol, which police fired through a similar area of the door to where the hole was found.

The video, which was played last week during the e…
