A constable who fell asleep at the wheel of a police minibus that mounted a pavement in Sai Kung and killed a shopowner was yesterday convicted of dangerous driving causing death. Duncan Chiu Wai-hong, 37, was found to have fallen asleep while driving along Hiram's Highway towards Kowloon. He was remanded in custody pending sentencing after having pleaded not guilty. Chiu claimed he had suffered temporary blindness before the accident and 'all things became white at that moment'. But magistrate Raymond Wong Kwok-fai pointed out a colleague of Chiu testified that the defendant had admitted falling asleep at the wheel of the vehicle. Mr Wong said the witness' evidence was credible as the officer had no relationship with Chiu. The magistrate said Chiu's own testimony also showed he was likely to have been tired at the time of the accident, which occurred in September last year near Sun On Tsuen. 'He failed to brake and negotiate a bend during the accident,' Mr Wong said. Kwun Tong Court heard that the minibus went straight on at a left-hand bend, crossing into the opposite lane and mounting the pavement, only coming to a stop after striking two lamp posts and two pedestrians. Tyre shop owner Kong Pak-chun, 53, died in the accident, while his employee Chow Wan-leung, 46, was seriously injured. The men, who had been standing outside their shop, were trapped under the minibus and had to be cut free by firemen. It was estimated that the vehicle had travelled 60 metres on the road and 16 metres on the pavement during the four seconds Chiu was asleep at the wheel. He was alone in the minibus while transporting documents to Marine Police headquarters.
