An autopsy will be conducted today on the body of a 16-year-old boy, reported missing since Saturday, whose body was found floating in the sea off Chai Wan with a neck injury. Police said the body of Eason Tsang, a jobless school dropout, was found by a man fishing at Ka Yip Street on Monday night. Marine police brought the body, decomposed but still stained with a large amount of blood, to their Sai Wan Ho base. Police estimate the boy, whose identity card was with him, had died at least two days earlier. They regard his death as suspicious. A person familiar with the investigation said police would not be able to determine the cause of death or how the injury was inflicted until the autopsy report was ready. 'Things will be clearer after forensic experts have conducted the autopsy,' he said. Tsang, who lived on the Hing Tung Estate in Chai Wan, dropped out of school a year ago and did not have a job, the person said. His parents' only son, he had left home on Friday and his family did not hear from him again. His parents reported him missing on Saturday. The parents claimed his body from the Sai Wan Ho marine police base yesterday and it was transferred to a mortuary in Western district. Family members performed religious rituals at the scene. It is understood that Tsang, who had a good relationship with his family, had no gambling or drug habits and was not in debt.
