In a significant legal development, a Melbourne magistrate has dismissed rape and constructive murder charges against a man accused of killing a sex worker, while allowing a standalone murder charge to proceed to trial. Michael James Chalmers, 36, will face Victoria’s Supreme Court exclusively on murder allegations following a judicial determination that insufficient evidence existed to support sexual assault claims.
The case centers on the death of a 62-year-old woman, identified by advocates as Yuko, who was discovered deceased at the Rainbow Garden brothel in Footscray on November 29, 2024. Prosecutors alleged Chalmers visited the establishment after conducting online searches for nearby brothels, with CCTV footage purportedly showing him entering a bedroom with the victim.
During Tuesday’s committal hearing, Magistrate Vincenzo Caltabiano evaluated the evidentiary basis for three initial charges: murder, rape, and constructive murder—defined as an unintentional killing occurring during sexual assault. The prosecution presented footage described as depicting “quite shocking acts of violence,” showing a man allegedly placing Yuko in a headlock before forcing her onto a bed.
Forensic evidence included Chalmers’ DNA on Yuko’s body and anal injuries that prosecutors argued indicated sexual assault. However, defense lawyer Barnaby Johnston successfully challenged this interpretation, noting that the victim had seen approximately a dozen clients in the week preceding her death, creating reasonable doubt about the origin of these injuries.
Magistrate Caltabiano ultimately found the medical evidence inconclusive, with the examining physician acknowledging that anal trauma could potentially result from non-assaultive causes. The court also heard conflicting pathological opinions regarding the exact cause of death, with one expert listing it as “unascertained” while another cited neck compression or smothering.
Chalmers formally entered a not guilty plea to the murder charge and will appear for a directions hearing in the Supreme Court on April 16. The case has drawn attention from sex worker advocacy groups, who held a vigil outside the courthouse proceedings.
