A CORONER'S jury yesterday returned a verdict of death by lawful killing on an illegal immigrant allegedly involved in a $1.3 million goldsmith's shop robbery. The jury also made two recommendations over the case involving a mainlander, who was about 30 and believed to be nicknamed ''Hui Bor''. His exact identity remains a mystery. The court heard that the deceased died of a gunshot wound to the chest in hospital on February 15. The jurors recommended police deployed at a serious crime scene be fully informed of potential risks. They also said officers should exercise special care when discharging firearms if hazardous substances, such as liquefied petroleum gas (LPG), were present. Detective Inspector James McIlveen, of the Regional Crime Unit (Team 1B, Hong Kong Island), said it had not been established which of the 12 shots fired by the officers at the scene had hit the deceased. During the two-day inquest, the court was told that the deceased and another man allegedly raided the Emperor Gold and Jewellery Company at King's Road, North Point. The two men and a third alleged accomplice hijacked businessman John Lee Siu-man and his car. He managed to disarm the gunman and run off. The alleged robbers later hijacked a lorry loaded with LPG. Police then opened fire.
