Chilling CCTV has emerged of accused killer Beau Lamarre-Condon in the days before and moments after he allegedly murdered Jesse Baird and Luke Davies.
The videos, obtained exclusively by 9News, show the 28-year-old senior constable entering and leaving a shop in Sydney's south on two separate occasions.
The first clip shows Lamarre-Condon and a friend walking into a sports store in Miranda two days before the alleged double murder, with the accused killer then walking out holding the surfboard bag police claim he used to transport Baird's body.

The second clip is taken just three hours after the alleged murders last Monday.
Lamarre-Condon is shown walking into the same store, this time by himself, and once again walks out with a single surfboard bag.
This one, police allege, was used for Davies' body.

Assistant Commissioner Michael Fitzgerald told 9News yesterday that police believe Baird's murder was planned and targeted, but that Davies was only killed because he was at his partner's Paddington house at the same time.
A different piece of new vision obtained by 9News shows a man in a black cap pulling up in a black SUV on the morning the couple were allegedly killed.
About 25 metres from Baird's terrace, the man gets out and then drives away at 9am, about 50 minutes before the two young men were allegedly gunned down with his police-issued pistol.

Police allege Lamarre-Condon returned to the house the following day in a rented van he used to move the bodies.
It wasn't until Tuesday that those bodies were found near the small NSW town of Bungonia, after the accused killer allegedly pointed out their location to officers.
Lamarre-Condon handed himself into police last Friday, before being arrested and later charged with two counts of murder.
He is currently detained in Silverwater prison.
