A woman who tried to commit suicide pleaded guilty yesterday to the manslaughter of her three-year-daughter last September. Prosecutor Dee Crebbin told the Court of First Instance that housewife So Yuet-kam, 34, tried to kill herself and her daughter after running up gambling debts. The court heard that on September 16, So placed burning charcoal inside a bedroom at her Tai Po flat, took sleeping pills and gave some to her daughter. Before retiring to the bedroom, So left a suicide note saying that their daughter wanted to die with her and apologising to her husband. Ms Crebbin said two psychiatrists who examined So in July and September concluded she was 'suffering from such an abnormality of mind, through her severe depressive disorder, as to substantially impair mental responsibility for her acts'. So was convicted of manslaughter on the basis of diminished responsibility. The prosecution told the court that on the day of the girl's death, So had revealed her plans to her friend, Kong Kwan-hing. But when Ms Kong and two other friends visited So's home to check on her, they received no answer when they knocked on the door. They then contacted So's husband, Tang Hung-chau, who returned home. When the four entered the flat, they found So and her daughter unconscious in the bedroom, with burning charcoal on the floor and the windows closed. The girl was pronounced dead on arrival at Alice Ho Miu Ling Nethersole Hospital. So was in a coma and initially listed in a critical condition, but regained full consciousness the next day. Mrs Justice Verina Bokhary called for two psychiatric reports on So and adjourned the case until November 10 for sentencing.
