Geometry of a Cover-Up: How Ballistics and Digital Traces Dissect a Police Officer’s Defence

When a former police officer stands accused of double murder, the defence strategy often rests on chaos—a sudden struggle, an unexpected escalation, a terrible panic. In the Sydney trial of 31-year-old Beau Lamarre-Condon, however, the prosecution has spent its recent courtroom hours painting a portrait of precise geometry and prior knowledge. Facing two counts of murder and a charge of aggravated break and enter, the ex-constable claims he acted in self-defence during two separate physical altercations. Yet the physical evidence assembled at the New South Wales Supreme Court suggests something far less spontaneous.

Inside the Paddington terrace house where Jesse Baird and Luke Davies were killed on 19 February 2024, bullet holes tell a precise story. A 3D computer reconstruction shown to the jury traced the alleged path of Lamarre-Condon through the home, mapping trajectory lines alongside photographs of damage inflicted by his police service weapon. The prosecution maintains that Baird was shot twice in the kitchen before Davies was killed through a closed bedroom door. Forensic firearms examiner Lucas Van Der Walt provided technical backing for this sequence, explaining that stippling—the distinct pattern of unburnt gunpowder particles—around a hole in the wooden door places the firearm's muzzle a mere 10 to 20 centimetres away when fired.

That same door had been hastily repaired with wood putty and concealed under a plastic hook, an intervention the defence framing attributes to a panicked aftermath. Van Der Walt's ballistics testing, conducted by firing the suspect firearm into the removed door under laboratory conditions, yielded a near-identical particle spread. Crucially, the presence of clear stippling directly on the painted wood undermines the defence suggestion that another body might have been standing between the barrel and the door at the time of discharge.

Beyond the ballistics, the geography of the alleged cover-up points to pre-existing familiarity rather than panicked wandering. Months before the killings, in November 2023, Lamarre-Condon had visited a rural property in Bungonia accompanied by an acquaintance met on a dating app. The farm, equipped with four dams and a padlocked gate, even featured on the officer's social media accounts. When the time came to dispose of the bodies of Baird and Davies, it was to these exact dams that Lamarre-Condon allegedly turned.

The attempt to submerge the remains in the farm’s waters ultimately failed, leading to their eventual discovery near a monastery fence line 20 kilometres away. As Justice Natalie Adams guides the jury through the technical arguments, the prosecution’s case relies on a simple premise: a trained officer does not accidentally fire a service weapon at point-blank range through a door, nor does he randomly choose a secluded rural farm with dams he had scouted months earlier. The trial continues as the court weighs forensic geometry against claims of blind panic.
