A mortuary attendant in the hospital where the body of a baby boy went missing could not recall if the body was in the same tray as an adult body when the adult body was removed on December 19, the Hospital Authority says in a paper submitted to the Legislative Council's health panel. The panel will discuss the paper at a meeting on the operation of mortuaries at public hospitals on Monday. According to a preliminary Hospital Authority investigation of the incident submitted to Legco, the body of the boy was wrapped in a dedicated body bag, which was clearly labelled, and sent to the Pamela Youde Nethersole Eastern Hospital mortuary on December 15. The body was placed in tray No3 in a special compartment designated for dead babies and large adult bodies. A large adult body was placed in the same compartment on December 17 and two name tags were placed on the door of the compartment to indicate two bodies were inside. The occupancy rate of the mortuary at the time was about 75 per cent. On December 19, the adult body was released to relatives, but the mortuary attendant who released the adult body could not recall if the baby's body was in the same tray. A mortuary technician conducted a routine fortnightly check on January 2 and discovered the baby's body was missing. The technician and attendant started a search for the body in the mortuary but failed to find it. The incident was reported to hospital management on Monday afternoon. A hospital source said the body of a boy was last seen several hours before the adult body was released. Police are investigating the incident. At least two police tactical unit platoons, more than 80 officers, will search Tseung Kwan O landfill for the baby's body from Monday. Environmental Protection Department officers and police yesterday discussed details of the search, in a special-treatment trench at the landfill used for the disposal of hazardous biochemical and clinical waste, and what kind of protective gear and disinfection procedures would be needed for the operation. As the clinical waste to be excavated from the trench is hazardous, environmental protection officers will help police dispose of the waste in another trench as soon as possible after the search. Secretary for Food and Health York Chow Yat-ngok said yesterday that while it would be very difficult to find the body at the landfill, the government hoped it could be located.
