My daughter moved too quickly for me to stop her, says grieving divorcee An 11-year-old girl leapt to her death from her Tuen Mun home during an argument with her mother yesterday - the fourth student to commit suicide within a month. Tai Suk-wah, a Primary Five student at Lau Tak Yung Memorial Primary School in Tuen Mun, had a row with her mother, 45, in their 11th-floor unit in Tip Ling House, Butterfly Estate, after waking up at 7am. According to her mother, they started to argue when the girl, who had not done her homework, refused to go to school. 'During the heated argument, she tried to run out of the flat but I blocked the exit. She then grabbed her schoolbag and hurled it on the floor before she rushed into the kitchen and jumped out of the window,' the mother said. The woman, a divorcee, said her daughter's suicide happened too quickly for her to stop it. She fainted after seeing her daughter leap out the window. The girl was taken unconscious to Tuen Mun Hospital, where she was declared dead before 8am. Police said an initial investigation showed there were no suspicious circumstances. The school headmaster, So Wai-ming, said all staff were shocked and saddened by Suk-wah's death. He said because of the girl's emotional problems, counsellors and guidance teachers at the school had paid particular attention to her since she enrolled in 2000. Yesterday afternoon, social workers and educational psychologists offered counselling to the pupils and teachers at the school. Five students have killed themselves this school year. In the past school year, 12 pupils committed suicide, down from 14 the year before. Nineteen students committed suicide in the 2000 to 2001 school year. A spokesman for the Education and Manpower Bureau said officials were concerned about the recent suicide cases. He said the government had taken different steps to tackle the problem and the number of suicides involving students had dropped over the past three years. On November 20, an 11-year-old schoolgirl hanged herself in her aunt's flat in Yan Shing Garden, Fanling. Five days later, a Form Five student, 19, plunged to his death from a public housing block in Sheung Shui. Earlier in November, Permanent Secretary for Education and Manpower Fanny Law Fan Chiu-fun described youngsters who took their own lives as 'irresponsible, selfish and cowardly'. Mrs Law's comments came a day after a 15-year-old schoolgirl jumped to her death in Tin Shui Wai on November 11.
