The 31-year-old former senior constable - and Taylor Swift fan - has pleaded not guilty to murdering ex-partner Jesse Baird and Mr Baird's new boyfriend Luke Davies on February 19, 2024.
A childhood friend of the officer, known by the pseudonym Elizabeth Kennedy, told the court she unwillingly accompanied Lamarre-Condon on a 200km trip south to Bungonia two days later where he attempted to dump the bodies.
But Lamarre-Condon's barrister suggested in cross-examination that Ms Kennedy was the one who encouraged the disposal of the bodies.
"Did you say: 'I watch a lot of crime documentaries, we have to hide the bodies, they won't believe you?'" John Stratton SC asked.
"No," Ms Kennedy replied.
Mr Stratton asked whether Ms Kennedy, a fellow Swiftie, referenced one of the pop star's songs emphasising the gravity of the officer's situation.
"No, no, no ... they won't believe you, this is like the Taylor Swift song 'No Body, No Crime'," Ms Kennedy was asked if she said to the accused.
But the officer's friend denied bringing up the song, saying it was Lamarre-Condon who raised the music icon.
"He was the one who put that song on in the car ... it's not one of her mainstream songs," Ms Kennedy said.
"I tried to play a few more songs from the album and he didn't know any of them."
Mr Stratton also challenged Ms Kennedy's evidence she never noticed anything out of the ordinary in the back of the van.
"(He) showed you the head of the deceased Jesse Baird ... (you said) 'Oh my God, I saw his head, you're not joking'," Mr Stratton said.
"No ... he definitely didn't want me to know there was anything in the back," Ms Kennedy replied.
She has not been charged with any offences relating to the deaths of Mr Baird and Mr Davies.
She gave an induced statement to police, protecting her evidence from being used against her.
When they reached Goulburn, Lamarre-Condon made Ms Kennedy buy him an angle grinder from Bunnings, she said.
Ms Kennedy said he took a long time to cut the padlock using the angle grinder after arriving at Cella Farm.
She said he then left her at the gate and drove into the property, where he stayed 30 to 40 minutes.
Lamarre-Condon allegedly attempted to dispose of the men's bodies in a dam using gym weights and quick-set concrete, the Crown claims.
The 31-year-old is also accused of breaking into Mr Baird's house - allegedly using a key he had secretly cut for himself - in August 2023 and stealing his ex's phone and wallet.
"I put to you that the accused never told you he had a key cut," Mr Stratton said.
"You're very wrong, he told me that face-to-face," she said.
Earlier in the NSW Supreme Court trial, jurors were shown extensive CCTV footage of the two days after Mr Baird and Mr Davies were killed.
On February 20, a disguised figure alleged to be the then-28-year-old police officer can be seen walking towards Mr Baird's house carrying a bucket.
Later, Lamarre-Condon is seen making multiple purchases at Bunnings Alexandria, including a power drill and hi-vis clothing.
That evening, he picked up a friend, yet to give evidence at trial, and went with him to dinner at a Sushi Train restaurant in Cronulla.
The Crown alleges the friend seen with Lamarre-Condon at Sushi Train is the same person seen on CCTV buying a surfboard bag with the officer three days earlier.
When driving the friend back to his house, the accused's Tesla can be seen stopping at Club Cronulla.
A man, alleged to be the friend, gets out of the passenger side of the car and inspects a skip bin in the car park.
Later that night, the same camera at the bowling club captures a white van pulling into the car park.
A figure lifts the bin lids and dumps items in it.
The bloodied belongings of Mr Baird and Mr Davies were found in the bin by a groundskeeper at the club the following day.
The trial continues.
