A 40-year-old pregnant woman surnamed Hsu, with a prior drug record, passed away after feeling unwell at her boyfriend's home in Chiayi. Despite an emergency C-section, the 7-month-old fetus also died. Police found residues of 'Etomidate' (zombie smoke bombs) at the residence, and her boyfriend admitted to drug use. Prosecutors will conduct an autopsy on May 20 to clarify the cause of death.
