A man who killed his elderly landlady after using his 11-year-old daughter as an unwitting decoy was yesterday jailed for nine years. Check Sze-yip, 59, gained access to neighbour Chau Chau-kam's home by sending his daughter round with a bowl of soup. Moments later, the 76-year-old grandmother was tied up and strangled. Check and an accomplice who fled to the mainland escaped with jewellery and cash after ransacking the flat in Ping Shan, Yuen Long, on October 11 last year. Mr Justice Arthur Leong Shiu-chung told Check his crime was 'especially heinous' because of the way he tricked his way into Chau's home by pretending to return her kindness. In a surprise verdict on Tuesday, the jury acquitted Check of murder, but convicted him of manslaughter and robbery. Yesterday, his counsel Robert Forrest told the Court of First Instance Check might have been little more than a lookout man. Legal sources said the sentence was light, given the crime was at the worse end of the scale for manslaughter.
