A man collapsed after a coroner ruled his 51-year-old wife's death was accidental. Leung Wai-yee was killed by falling masonry last November 9, just days before her planned retirement. She suffered multiple injuries when the bus on which she was travelling was hit by debris from a nine-storey building under demolition. Her husband, only known as Mr Lo, who has a history of heart problems, fainted as he was leaving the court with his two sons. He was taken to Eastern Hospital. Outside the court, the family refused to comment fearing it might prejudice any future proceedings. Coroner John Saunders heard from a government engineer that an amended building law to strengthen supervision of demolition works had been submitted to the Legislative Council. The inquest was told a consultant had been appointed to advise on safe demolition and to prepare a code of practice. With effect from April, statements of any approved demolition methods and associated working procedures should be written in both English and Chinese. Mr Saunders found in the fatal incident, supervisor Luk Wai-shing had not consulted the site architect or other authorised persons as required after he found a crack at the building in San Po Kong. The inquest heard Mr Luk instead decided to pull down the parapet wall on the rooftop with cables and ropes. The coroner rejected evidence by worker Chow Kin-on who said he had signalled traffic to go farther away from the site.
