Crown prosecutors and Beau Lamarre-Condon’s defence team finished opening statements in the NSW Supreme Court on Tuesday.

Beau Lamarre-Condon’s defence lawyer John Stratton told the court his client went into his ex-boyfriend Jesse Baird’s house to recover some jewellery, rather than to kill him.

He said his client ‘didn’t want to go through the embarrassment’ of meeting Baird that morning.

The court heard that he waited until no one was home, and then let himself in dressed as an Uber Eats driver in case anyone came to the door.

Mr Stratton said Baird was holding a knife and didn’t recognise Lamarre-Condon because he was wearing a motorbike helmet and high-vis.

Lamarre-Condon was carrying his gun because he was trained as a police officer to never leave a gun in the car where it might be stolen, the court heard.

Mr Stratton said Baird grabbed the gun, there was a struggle, and the gun went off, fatally wounding Baird.

The gun was flung into the living room, the court heard, before Lamarre-Condon started walking down the hall while calling Triple-0.

He then came across Luke Davies, Baird’s new boyfriend, the court heard.

Lamarre-Condon grabbed Davies by the arm and pushed the gun away from himself, before Davies pulled the trigger and fatally shot himself.

Mr Stratton told the court that Lamarre-Condon never intended to harm anyone in Paddington that day, and that he acted in self-defence.

‘After that, the accused panicked, he knew it looked bad,’ Mr Stratton said.

‘He cleaned up as much as he could and threw the knife into the yard of a house on Lawson street.’

Mr Stratton also said his client never broke into Baird’s house in August 2023, but he let himself in because he had been given a key.

The court heard Lamarre-Condon took his break-up with Baird badly and ‘did stupid things, like looking through Baird’s phone and deleting messages’.

Gunshot sounds that were captured on security footage in the front yard of Jesse Baird’s neighbour in Paddington on the day of the alleged double murder were played for the court.

Crown prosecutor Brett Hatfield alleged the three shots heard in the footage were the same ones that killed Baird and his partner Luke Davies.

Mr Hatfield also alleged Lamarre-Condon told the friend he ‘killed two people’, and that his job as a senior constable had ‘f***ed me up’.

When the friend asked how he allegedly killed two people, Lamarre-Condon replied: ‘Pew pew.’

The court heard Lamarre-Condon stopped at a Westfield in Miranda, Sydney’s south, after the alleged murders and bought a second surfboard case – he already had one – for $85 from a Decathlon store.

He then allegedly went to Bunnings in Alexandria in Sydney’s west, and bought a bucket, mop, bleach, black cable ties, a 20-pack of cleaning cloths, double-sided tape, and garbage bags.

Lamarre-Condon also allegedly made a complaint about the NSW Police Force while on his way to hand himself in for the alleged murders of Baird and Davies, the court heard.

During that phone call, he said: ‘I’ve been bullied, but when I reported it, no action was taken … All this death and trauma and psychological abuse … Did I say trauma already?

‘… It has caused me to have symptoms of schizophrenia … sorry, can we start again? Delete the whole thing, we’ll just keep it short and sweet.’

He then handed himself in to detectives in Bondi, the court heard, during which he allegedly said he took medication for depression and schizophrenia, but couldn’t remember what the medication was called.

Crown prosecutor Brett Hatfield SC told the court Lamarre-Condon was not on any medication for mental health issues, and that mental health impairment did not form part of his defence.

Baird’s sister Courtney (pictured above in white trousers) told the court her brother was ‘fearful’ because Lamarre-Condon was a police officer with a weapon, and that he would block Baird’s contacts on his phone.

She also told the court that her brother believed he was being followed.

‘He got messages [from Lamarre-Condon] saying “you looked really good in the gym tonight”, or when he was out for coffee or a meal he would often receive messages saying he looked nice in what he was wearing.’

Baird’s mother (pictured above in black) broke down on the stand while talking about her son.
