Sydney model Revelle Balmain is at the centre of a long-running cold case after authorities name her former bosses as persons of interest, according to multiple reports. The articles say Balmain had planned to meet friends for a farewell before travelling to Japan, but she never turned up. The reports do not agree on additional investigative details, but they consistently frame the matter around the same timeline and the same individuals being identified as persons of interest. Each source notes that Balmain’s disappearance remains unresolved and is being treated as a cold case, prompting continued police attention and further inquiries. The outlets also describe the lack of resolution and the continued efforts to understand what happened to Balmain before her intended departure. Collectively, the reporting indicates that investigators are focusing on people who worked with or around Balmain in the period before she was last seen, and that the case continues to rely on information gathered through ongoing review of earlier evidence and new leads.
