Former colleagues of constable Tsui Po-ko told the Coroner's Court how they were impressed by his fondness for sport and reading, his quiet nature and self-confidence. A psychological report revealed Tsui had been self-confident and independent from a very young age. He was tough and suppressed his emotions. The Testimony Woman constable Law Wai-fun, 37, told the inquest Tsui drove her team to the scene of a bank robbery in Tsuen Wan he is believed to have committed. Constable Suen Wai-kuen, 40, was Tsui's colleague in Chek Lap Kok when the airport was still being built in 1997. 'I remember Tsui fired six bullets into the head of the silhouette in a shooting session and our trainer told him to target the lower part instead.' The court heard that targeting the trunk increased accuracy and the objective when opening fire was to subdue rather than kill. Police clinical psychologist Ephraem Tsui Pui-wan said Tsui could have been affected by his parents' divorce, especially when told by his mother that the separation was her fault. 'He might have thought the separation was his father's fault. When his mother told him this, he might have been very confused and reacted to it with anger. When he was rejected for promotion, he could have been very disappointed and angry.' Dr Tsui presented and analysed 16 letters Tsui wrote to his wife in 1998, telling her that he was going to travel alone and promising he would treat her better. Tsui had shown he wanted a promotion to inspector within two years. Today The inquest will continue with the psychological report and further forensic evidence on the Tsim Sha Tsui shoot-out.
