New details reveal accused killer cop’s alleged cover-up attempts

New details have emerged about the alleged steps Beau Lamarre-Condon took to cover up the murders of Jesse Baird and Luke Davies.

Police will allege investigators "found three cleaners in the process of cleaning the premises" on February 21 when they arrived at the Paddington terrace where the alleged murders took place two days earlier, a statement of facts sheet obtained by the Sydney Morning Herald and seen by 9News reveals.

It states that cleaners had "mopped half the wooden floor before police arrived and stopped them".

Investigators said they found "blood staining" underneath the floorboards in the kitchen and in Baird's bedroom that was "consistent with a body bleeding heavily", as well as bullet holes and a .40 calibre cartridge in the kitchen.

Police will allege a phone call was made to triple zero from Davies' phone at the time of the alleged murders, with a male voice heard shouting "get out, f— off" before the call was terminated.

At 8pm that same night, a housemate returned to the Paddington home and saw two surfboard bags lying outside near the roller door.

They were covered with a tarpaulin and the housemate took three photographs "and prodded them with their finger", unaware there were bodies inside.

Lamarre-Condon was arrested and charged over the murders last week.

Police have struggled to put a complete timeline together but allege Lamarre-Condon killed the couple on Monday, February 19, before hiring a van to move the bodies from the Paddington home on Monday night.

He allegedly messaged Baird's friends from his phone on Tuesday, before throwing bloodied items belonging to both Baird and Davies, in a skip-bin in Cronulla on Wednesday.

On Thursday, police allege, he drove to a friend's home in Newcastle, where he asked for a hose to clean out the van.
