Cross-examination of the 31-year-old continued on Monday over how Jesse Baird and Luke Davies were fatally shot at a Sydney home with his police pistol in February 2024.
Lamarre-Condon has pleaded not guilty to the two murders, claiming the men were killed in self-defence.
Holding rosary beads while under heated questioning by crown prosecutor Brett Hatfield SC, the former senior constable claimed evidence about his hire car use had been hidden from the jury.
While he admits using a Mazda hired in his mother's name on the day of the fatal shootings, he claims this was not to disguise himself but only because his mother's car was in for repairs.
He said there was evidence his mother's car was at the smash repairs for more than a month which was never shown to the jury.
"You didn't do an investigation because it doesn't suit your case," he remarked.
He also accused prosecutors of neglecting to show jurors the full CCTV footage of himself and a friend at a sushi restaurant "freaking out" after the alleged murders.
Lamarre-Condon has claimed he was suicidal when he visited Mr Baird's terrace home.
He denied suggestions by Mr Hatfield that these allegations were made to drum up sympathy with the jury.
"You weren't suicidal, you were homicidal," the prosecutor said.
"I was not," Lamarre-Condon replied.
Mr Hatfield also took the 31-year-old through various inconsistencies in his version of events, including claims he wanted to retrieve his surfboard from Mr Baird's home in February 2024.
Lamarre-Condon purchased a surfboard bag the day before shootings, and the two men's bodies were later found in surfboard bags buried at a rural monastery.
He told the court he took his surfboard over to Mr Baird's place when they were dating.
However, during a covertly recorded prison conversation in December 2025, Lamarre-Condon told a friend he had purchased a surfboard for his now deceased ex-partner.
The former police officer stood by his version of events.
Lamarre-Condon claims he shot Mr Baird in the shoulder as the victim came at him with a knife.
The pair then struggled and fell to the kitchen floor when the gun accidentally discharged, hitting Mr Baird in the head, he said.
"It's the case, isn't it, that you executed him by that second shot?" Mr Hatfield said earlier on Monday.
"I never executed Jesse Baird," Lamarre-Condon said.
He has admitted responsibility for Mr Baird's "unintentional" death.
He claims he put Mr Baird into a recovery position, called triple zero and headed outside to try to flag down a passing ambulance.
On the way out, he said he saw Mr Baird's new partner Luke Davies aiming the pistol at his head.
The pair struggled, leading to the firearm accidentally discharging again, according to Lamarre-Condon.
The bullet went through the other man's head, lodging in the bedroom door behind him, he told the jury.
"It discharged at his face. That obviously was never the plan," Lamarre-Condon said.
The Crown alleges he shot Mr Davies through the door as the latter man was calling triple zero in order to eliminate a witness.
He told the jury a "huge moral dilemma" prevented him from immediately going to police.
As a police officer behind bars, he could be stabbed or killed and those events had already come close to happening after he was remanded in custody, he said.
Prosecutors allege the former officer staked out Mr Baird's house for hours to wait until only his ex was left inside.
However, Lamarre-Condon claims he thought nobody was home when he went inside to try to recoup some belongings while disguised as an Uber Eats delivery rider.
The trial continues Tuesday.
