Police have vowed to leave no stone unturned in the search for the bodies of two missing men amid confirmation a patrol car responded to a triple-zero call made from one of the duo’s phones.

Beau Lamarre-Condon, 28, is behind bars after being charged with murdering ex-Network Ten reporter Jesse Baird, 26, and boyfriend Luke Davies, 29, in Sydney.

The senior constable is accused of using his police-issued firearm to kill the couple after entering Mr Baird’s home in inner-city Paddington on February 19.Play

Police on Tuesday confirmed a triple-zero call was made from Luke Davies’ mobile phone, rather than from Mr Baird’s phone as previously reported, four minutes after neighbours heard gunshots at the house.

A patrol car was later sent searching for the source of the call, which was disconnected before anyone spoke.

But officers were unable to locate the user and did not attend Mr Baird’s house at the time.

Investigators allege the crimes followed a months-long campaign of “predatory behaviour” by the charged officer, culminating in the fatal shooting at the Paddington home.

Mr Baird’s friend Isaac Muller said the former TV presenter and Lamarre-Condon were never in a relationship. 

“Jessie briefly had an encounter with Beau,” he told the ABC’s 7.30 program on Monday night.

“He was not his ex boyfriend … they never were going out.”

Police allege Lamarre-Condon acted alone but divulged “partial admissions” to others before he handed himself in.

Independent state MP and former police officer Rod Roberts questioned how the 28-year-old former celebrity blogger ever got a job with the force.

“His background in chasing celebrities doesn’t sound like it’s a fit for the police force,” he told Sydney radio 2GB on Tuesday.

Mr Roberts added Lamarre-Condon’s supervisors and senior officers should have picked up any red flags “much earlier”.

NSW Police officers on Sunday began to search dams at a property in Bungonia, near Goulburn almost 200km southeast of Sydney.

Investigators believe Lamarre-Condon could have dumped the men’s bodies at the site, before returning later to move them to another, unknown location.

A search of rural land near to the property was expected to continue into Tuesday.

NSW Police Commissioner Karen Webb said investigators were “leaving no stone unturned” in the search for the two men’s bodies.

“Police are still on site conducting line searches in and around the area,” she told Nine’s Today program.

“We believe there’s still evidence in that area that might link the murders and the victims to that scene.”

Lamarre-Condon has exercised his right to silence after receiving legal advice.
