Michael Chalmers: Experts differ on cause of death for sex worker as accused killer faces court

A pivotal committal hearing for accused murderer Michael James Chalmers, 36, has been marked by conflicting medical testimony from forensic experts regarding the death of a 62-year-old sex worker. The proceedings at Melbourne Magistrates’ Court will determine whether sufficient evidence exists to proceed to trial for the alleged November 2024 killing.

According to police allegations, Chalmers raped and murdered the victim, whose body was discovered during a welfare check at the Rainbow Garden brothel in Footscray on November 29. Investigators contend the killing occurred in the early hours of November 27, based on the victim’s last known communication on November 26.

The forensic investigation has produced divergent conclusions from two pathologists. Dr. Joanne Ho classified the cause of death as “unascertained” while noting physical indicators consistent with asphyxiation through strangulation or smothering. However, Dr. Ho acknowledged that facial bruising and other injuries might be unrelated to the fatal mechanism, leaving open the possibility of alternative causes.

In contrast, Dr. Joanna Glengarry, head of forensic pathology at the Victorian Institute of Forensic Medicine, testified that the victim died from “broad neck compression.” Dr. Glengarry concurred with defense suggestions that asphyxiation could result from various mechanisms, including compression from being sat upon.

Detective Senior Constable Daniel Fallone, leading the investigation, revealed that CCTV footage identified three patrons visiting the establishment within the 24-hour period preceding the alleged murder. Two additional men approached the brothel after the estimated time of death but departed without entering. The investigation also uncovered that the victim had been prescribed medication for a heart condition and had reported at least one client assault in the weeks before her death, though these reports were not made to police.

The hearing will resume next Monday after defense attorneys submit written arguments regarding the contradictory medical evidence and overall case viability.
