Blood, a hire van and a remote property: a timeline of the search for Jesse Baird and Luke Davies

New South Wales police say they have found the bodies of Jesse Baird and Luke Davies four days after one of their officers, Sen Const Beau Lamarre, was charged with murdering the two men.

The story has horrified Sydney and Australia. Police previously said Lamarre was not assisting them with inquiries but that on Tuesday he disclosed the location of Baird’s and Davies’ bodies.

Here’s what we know about the Sydney couple’s disappearance and the alleged involvement of Lamarre.

Friday 16 February

Lamarre allegedly took a force-issued handgun from storage at the Miranda police station in south Sydney.

Lamarre signed the gun to work at a “protest activity” happening on Sunday 18 February, police say. It is unclear whether he actually worked at the event.

It was a “user pays” event where police officers are hired for private events – such as music festivals and rallies. Organisers pay for policing services.

9.50am – Neighbours hear gunshots at Baird’s home in Paddington, police say. The shots were not reported to police until days later.

9.54am – An emergency call is made to triple zero from Davies’ phone but is terminated before being connected to an operator.

Later that evening – Lamarre allegedly hires a white Toyota HiAce van from Sydney airport.

Tuesday 20 February

Lamarre allegedly makes “partial admissions” about the killings “to an acquaintance of having been involved in the deaths of two individuals”, police say.

Police allege at some point between Tuesday and Wednesday morning, Lamarre drove the hired van to Cronulla and discarded some personal items of former TV presenter and AFL umpire Baird, 26, and Qantas flight attendant Davies, 29.

Wednesday 21 February

11am – Bloodied clothing and personal items are found in a skip bin in Cronulla, which leads police to launch a missing person investigation. The homicide squad is notified.

Later that afternoon – Investigators search Davies’ home in Waterloo.

During the same day – Police allege Lamarre attends a Bungonia property near Goulburn with an acquaintance. The acquaintance is described by police as “an innocent agent”.

Lamarre and the acquaintance allegedly buy an angle grinder and a padlock from a hardware store in the area before driving to the gates of the property in the NSW southern tablelands.

Lamarre allegedly cuts the padlock with the grinder and proceeds into the property in the hired van. The acquaintance says they wait at the entrance at the top of the property for about half an hour.

After Lamarre places a new padlock on the property’s gate, the pair drive back to Sydney later that afternoon, police say.

Police say the acquaintance who visited the property with Lamarre is a “long-term friend of the accused” and “we don’t believe she was fully aware of what had taken place”.

Detectives say they believe the Bungonia property was previously visited by Lamarre through a former relationship.

11pm – Lamarre allegedly buys weights from a department store.

Police allege Lamarre then returns to the rural property near Goulburn during that evening or overnight. Lamarre allegedly acquires two torches from the acquaintance before he returns.

Thursday 22 February

4.30am – Lamarre allegedly leaves the Bungonia area again in the hired white van and drives back to Sydney.

It is believed Lamarre drove to the city and remained in that area before he attended another acquaintance’s home in Newcastle.

Lamarre didn’t disclose anything to this acquaintance but asked for access to a hose to clean the van, police allege.

11.30pm – Detectives say a third person – later identified as Lamarre – “may be able to assist with investigation”. They raid a home in Balmain thought to be connected to Lamarre.

4pm – Lamarre appears before Waverley local court. He does not apply for bail and the matter is adjourned to 23 April.
