A young mother broke down as she was led away yesterday to begin a 10-year jail term for killing her live-in lover and keeping his body in a box of salt. Yik Po-man, 20, showed no emotion as a jury cleared her of murder but convicted her of manslaughter on the basis of lack of intent to kill Cheung Wai-man, 22, or cause him serious bodily harm. But when the judge left the courtroom the young mother burst into tears. Cheung's body - minus its left arm and leg - was found inside a metal box of salt at their home in Tai Hing Estate, Tuen Mun, on February 14 last year - about four days after the incident. Yik, together with her daughter, moved home twice but was caught by police in Sham Shui Po on February 22. The girl, now four, has since been placed with foster parents. Yik denied murder but admitted manslaughter and prevention of the lawful burial of a body. Prosecutors had put her on trial for murder. Defence lawyer John Mullick, pleading in mitigation, said: 'She lived a double life for several years and that could not have been a happy time for her. It certainly cannot be denied that the deceased might have used violence towards her.' Yik had testified that her relationship with Cheung started after he raped her as a schoolgirl. She also accused him of often beating her up for no reason. The court heard that on the night of the killing, Cheung confronted Yik, then 19, for infidelity and attacked her. She fetched a knife and stabbed him. Passing sentence, Madam Justice Clare-Marie Beeson said: 'His body was treated with great disrespect and that must have caused great pain to his family.'
