Bayley’s extensive violent criminal history later generated intense outrage after it emerged he had previously committed multiple sexual and violent offenses before being released on parole.

Beau Lamarre-Condon is a former New South Wales Police senior constable accused of murdering television presenter Jesse Baird and Baird's partner, Luke Davies, in Sydney on February 19, 2024.

The prosecution alleges Lamarre-Condon developed an obsessive and jealous fixation on Baird, stalked him and ultimately entered his Paddington home armed with his police pistol. Prosecutors allege he shot Baird and Davies before transporting their bodies to a rural property near Bungonia. Lamarre-Condon has pleaded not guilty to two counts of murder and one count of aggravated break and enter.

His conviction became one of the country’s most high-profile murder cases, inspiring documentaries, books and films while generating decades of speculation about what truly happened in the Outback. Murdoch maintained his innocence until his death from throat cancer in 2025, never revealing the location of Falconio’s remains.
