A FORMER policeman, who had been on the run for 10 years, fled a 30th floor flat from which his girlfriend had fallen to her death, the Coroner's Court was told yesterday. Chan Kam-yui, 27, a former masseuse, was found dead on the second floor podium of a City One block in Sha Tin early on September 23 last year. The cause of death was multiple injuries. Her boyfriend, Chan Kwok-keung, 47, said he had fled because he was frightened that police might look for him. He said he had met Chan Kam-yui about two years ago and later moved in with her at her flat in City One. The court was told that Chan Kam-yui was depressed after she had lost a large sum of money on foreign currency speculation. Chan Kwok-keung said he fled because he knew he was suspected of involvement in a theft case dating back 10 years. Questioned by Coroner's officer Paul Madigan, he admitted that the first thing that came to his mind was to leave the scene since his identity might be disclosed. Asked whether it was more important to find out whether Chan Kam-yui was alive or not, he said: ''In a split second, I could not decide. If the police came, they might find out something happened.'' He testified that he packed up photographs and some clothing, and fled after checking the police had not yet arrived. He said he met the building's watchman downstairs, who told him Chan Kam-yui had jumped. The witness said he went into hiding but surrendered to police on September 26 after reading newspaper reports that accused him of involvement in the alleged murder of Chan Kam-yui. He testified that he gave himself up to show his innocence. Chan Kwok-keung told the court he and Chan Kam-yui had gone to bed at about 10 pm on September 22. When he woke at about 4.50 am, he found his girlfriend was missing. He checked the flat and later found the window open and its metal grille loosened. He said he paused for a while and thought she might have jumped. The witness, who said he was nervous at the time, said he pulled the grille aside but could not see anything. He then turned on the television set and switched to the channel showing the surveillance camera of the building to see whether police had arrived. The witness testified that he had tried to cheer up his girlfriend by raising about $200,000 and depositing it into her investment account several days before she died to help her to recoup her investment losses. But her brother-in-law, Tsang Chak-lung, and cousin testified that they did not think she had committed suicide, adding that Chan Kam-yui had been strong and cheerful. Forensics expert Ms Nora Cheung told the court that if Chan Kam-yui did jump from the window, then either someone had closed it or Chan Kam-yui had from the outside while balanced on the ledge. Coroner Warner Banks will sum up today.
