Christy Chan Yin-lam, a 15-year-old student, died on or shortly after 19 September 2019. Her naked corpse was found floating in the sea near Yau Tong, Hong Kong on 22 September 2019. Following a preliminary autopsy, police asserted that no foul play was suspected and that Chan had killed herself, while some protesters spread conspiracy theories alleging she was murdered by Hong Kong authorities in connection with her participation in the 2019 Hong Kong protests. The coroner's inquest concluded with the jury unanimously returning an open verdict, as the cause of death could not be determined, after Magistrate Ko Wai-hung ruled out both homicide and suicide as possible causes due to insufficient evidence to support this.
