Hundreds are set to gather to commemorate the lives of murdered couple Jesse Baird and Luke Davies on the eve of Mardi Gras.

The memorial, at Green Park in Sydney’s inner-city suburb of Darlinghurst at 6pm, will be held one week after NSW police Senior Constable Beau Lamarre-Condon handed himself into a police station after allegedly firing three bullets and killing the couple with his service Glock, with detectives of the belief that the gunshots were captured on CCTV audio just after 9.30am on Monday, ­February 19.

Following the vigil on Friday, a separate rally not affiliated with the vigil has been organised at the centre of where Saturday’s Mardi Gras parade will be held, calling for the sacking of the Mardi Gras board after they did an about-face on their decision to ban police from the event. Police are now permitted to march in the parade, but not in uniform.

A floral tribute has continued to grow at the home in which the couple died.

Eerie footage has emerged showing Constable Lamarre-Condon entering a sporting goods shop at Westfield Miranda two days before the alleged murders, where he can be see walking out of the store with another male carrying one bag. Police believe he was intending on killing only Mr Baird. Two days later, he allegedly returned to the same store to purchase a second bag, after he also allegedly murdered Mr Davies.

It has since been reported that Constable Lamarre-Condon stole bullets from a gun range to refill his weapon so that his pistol was returned without bullets missing.

NSW Police Force Assistant Commissioner Michael Fitzgerald said police would be alleging Constable Lamarre-Condon’s offending escalated, commencing with the keying of Mr Baird’s car, then breaking into his house and pouring water into the engine block of his vehicle.

A former NSW police officer, Renee Fortuna, is said to have contacted Crime Stoppers after becoming suspicious of Constable Lamarre-Condon, who had travelled to her home in Newcastle where he asked to borrow her hose to clean his van after dumping the bodies of Mr Baird and Mr Davies at Bungonia.

Ms Fortuna and Constable ­Lamarre-Condon had previously worked together at the Youth and Crime Prevention Command.

Meanwhile, the formal procedure of having Constable Lamarre-Condon removed as an officer of the NSW Police Force has begun.
