Murder of Jesse Baird was ‘premeditated,’ police allege

Police will allege the murder of Jesse Baird was premeditated by Beau Lamarre-Condon but his partner Luke Davies was killed only for being in the Sydney home at the time.

Assistant Commissioner Michael Fitzgerald told 9News reporter Damian Ryan police believe Baird's murder was planned and targeted.

Police believe Lamarre-Condon, a serving senior constable, was looking for Baird on Monday last week but also found Davies at the Paddington terrace.

"We will be strongly claiming in our case that this murder was premeditated, and the second murder occurred because of unfortunately Luke's appearance at the house," Fitzgerald said.

Both men were allegedly killed with the officer's service pistol.

Police allege Lamarre-Condon purchased a surfboard bag at Miranda two days before the fatal shootings.

But, detectives claim, he had to go back and buy a second one after he allegedly killed Davies, who was not the initial target.

They claim there's also evidence of the accused police officer's behaviour towards Baird escalating in the weeks leading up to the alleged murder.

He is accused of breaking into Baird's house, keying his car and pouring water into his car's engine block.

Fitzgerald revealed police believe the men's bodies had been left at a different property in Bungonia for a day and a half before they were moved to the second location where they were eventually found.

Detectives were still at the first property in Bungonia and quickly rushed to the second property to uncover the bodies after information was provided to police by Lamarre-Condon at Silverwater jail yesterday morning.

"He agreed at the time to show us where the bodies were, he showed those detectives after we acquired a computer … (for him) to point exactly where the location of the two deceased were," he said.
