But mother must share some of the blame as she did not contact babysitter who left boy home alone A babysitter working illegally was yesterday sentenced to eight months in jail for leaving a six-year-old autistic boy alone at home, where he later fell out of a window and died. Liu Yufang, 65, a two-way permit holder from Guangzhou, was convicted after pleading guilty to one count of breach of condition of stay and one of ill-treatment or neglect of a child. Tuen Mun Magistrate Joseph Yau Chi-lap described the incident as a tragedy that should act as a warning to the public. 'As adults, parents or custodians of children, they should take care of children. We wish to avoid a repeat of this tragedy,' Mr Yau said. Liu's attorney, Cecilia Liang Sun-yin, said Liu had not been told Cheuk-hei, who did not habitually climb out of windows, was autistic. But Mr Yau said Liu had been working in the home for more than 20 days and should have known the child needed special care. Prosecutor Leslie Yeung told the court yesterday Liu had entered Hong Kong on a two-way permit, for a three-month period, on January 20 this year. Her brother had introduced her to Mok-Tsz-tuen, 37, the mother of six-year-old Ho Cheuk-hei and a 12-year-old boy. Liu began working for Ms Mok as a baby sitter on March 27, staying with the family in their seventh-floor flat in an estate in Tin Shui Wai. On April 18, Liu's last day of work, Ms Mok had an appointment at 3pm that required her to leave the home. She gave Liu a mobile phone number and told her to call her after collecting Cheuk-hei from school. But Ms Mok was using a different mobile phone and Liu was unable to reach her, the prosecutor said. Liu, who had been paid on April 17, was due to return to the mainland on April 19, and had told Ms Mok she needed to leave by 6pm, Ms Liang said. She waited until 6.30pm before leaving. The prosecutor suggested Liu had been in a hurry to pack. She had left a note for Ms Mok and, expecting her or her elder son home soon, had left the key in the metal grille. A neighbour and a student heard Cheuk-hei crying for his mother, and one resident saw the boy at the kitchen window before he fell. Cheuk-hei hit a clothing rack before landing head first on the ground. Police found all the window guards in the flat hand been secured except in the kitchen. They also found Cheuk-hei's palm print at the opened window. Ms Mok had only called home at 7pm. Liu had not realised the danger of leaving the boy alone and sympathised with the family. Mr Yau said Ms Mok also had to accept some of the blame, as she had known Liu had to leave at 6pm and had not tried to contact her. Outside the court, Liu's brother Lau Yiu-wah said the sentence was reasonable but that Ms Mok should also shoulder responsibility.
