Accused double-murderer Beau Lamarre-Condon denies he executed his former partner by shooting him in the head to ensure he was dead.

Cross examination of the 31-year-old former police officer continued on Monday into his recount of how Jesse Baird and Luke Davies were fatally shot with his service pistol in February 2024.

Lamarre-Condon has pleaded not guilty to the two murders, saying both men were killed in self-defence.

Crown prosecutor Brett Hatfield SC took Lamarre-Condon through his claimed struggle with Baird in the kitchen of the now deceased man’s Sydney terrace house.

Hatfield took Lamarre-Condon through his previous evidence that he had shot Baird in the shoulder as he was coming at him with a knife. Lamarre-Condon has said the pair then struggled and fell to the kitchen floor when the gun accidentally discharged, hitting Baird in the head.

“It’s the case, isn’t it, that you executed him by that second shot?” Hatfield said.

“I never executed Jesse Baird,” Lamarre-Condon said.

The 31-year-old repeatedly physically motioned to show the jury how the alleged struggle played out. At one stage, he put down rosary beads he was carrying to demonstrate what he alleges happened.

He has admitted responsibility for Baird’s death but insists it was not intentional.

He said the pistol was flung towards the living room during the altercation.

Despite a lot of blood as his ex lay on the floor, Lamarre-Condon said he did not know Baird had been shot through the head.

“That’s your truthful evidence, is it?” Hatfield said.

“Yes, I’m being truthful,” Lamarre-Condon said.

He said he put Baird into a recovery position, called triple zero and headed out to the street to try to flag down a passing ambulance.

On the way out, he said he saw Baird’s new partner Luke Davies blocking the way out while holding the pistol.

The 31-year-old told jurors he put his hands over his head and told Davies he was not there to hurt him. But Davies aimed the gun at his head and the pair struggled, leading to the firearm accidentally discharging again.

The bullet went through Davies’ head, lodging into the bedroom door behind him, Lamarre-Condon told the jury.

“It discharged at his face. That obviously was never the plan,” he said.

The Crown alleges Lamarre-Condon shot Davies through the door as he was calling triple zero, to eliminate a witness.

On Monday, he said the bullet went through Davies’ head first, saying he had to clean blood from the door.

“You didn’t leave any traces of blood on that external door?” Hatfield said.

“I cleaned what I could see,” Lamarre-Condon said.

The Crown alleges Lamarre-Condon staked out Baird’s house for hours on the morning of February 19, 2024. to wait until only his ex remained inside.

But he told the court during his evidence-in-chief that he thought nobody was home when he went inside to try to find some belongings.

He said he searched the Paddington terrace house – disguised in an Uber Eats driver outfit with high-vis shirt and motorcycle helmet – to retrieve expensive shirts and a Cartier ring.

The failure to lift his visor allegedly led to the mistaken identity at the heart of Baird’s death, where Lamarre-Condon says his ex lunged at him with a knife thinking he was an intruder.

But the prosecution says he always intended to kill Baird and the disguise was simply a way to avoid being identified on CCTV.

Prosecutors allege Lamarre-Condon was motivated by jealous obsession when he shot Baird execution style.

The trial continues.
