A divorced couple killed by a landslide that hit their hut in Tuen Mun during a rainstorm in 2008 died by accident, a coroner ruled. Lu Shuangfeng , 30, and Xie Yongsheng , 32, suffocated in the mud that filled the hut, Coroner William Ng Sing-wai said. He recommended the Development Bureau install a warning system to monitor slopes that fall below safety standards before consolidation work can be done. Also, the bureau should educate the public about ways to find out the safety of slopes near their homes, he said. It seemed that residents living below the slope had little knowledge of it. The ruling did not please Xie's eldest brother, Tse Wing-Ngan, who said a government department should be held responsible. 'The slope was already assessed to be below the safety standard, but the report said [the landslide] was caused by heavy rain. It's an excuse,' Tse said. The pair died after a 30-tonne concrete wall fell on the hut at Cafeteria Old Beach, Castle Peak Road, at 6am on June 7. It took 12 hours for rescuers to recover their bodies. The court heard that in mid-2007, a consultant company evaluated the slope for the Civil Engineering and Development Department and said it did not pose imminent danger but fell below the safety standard. On May 19, 2008, the department ordered consolidation work on the slope, which was due to start on June 22, Ng said. But the landslide occurred before the work could start because of persistent rainfall. The couple, from a village in Guangdong, were staying with Lu's twin sister, Lo Mau-tan, who ran a food stall and barbecue venue at Cafeteria Old Beach. They left two sons, 12 and 13, on the mainland, Tse said. He said he was one of their closest relatives but the two orphans could not come to Hong Kong to stay with him. The family would seek Legal Aid Department help to claim compensation to support the children. Ng said he could understand why there was a time gap, but it was problematic. 'Even if a slope does not pose imminent danger, the situation can change, which reduces its stability,' he said. One of the changes that occurred was the mass clearing of vegetation on the top of the slope, which loosened the soil, he said. 'When there is heavy rainfall, the government tells the public to stay in safe places. Residents need to know whether [their home] is a safe place to make an informed decision,' he said.
