Woman cut off lover's penis and beat him to death with hammer after he forced her to have sex

A woman drugged her lover, cut off his penis and bludgeoned him to death with a hammer after he forcibly had sex with her, the High Court heard yesterday.

Yeung Ki, 41, fed Zhou Hui, 32, soup laced with sleeping pills before raining "almost uncountable" blows to his face and the back of his head, prosecutor Nicholas Adams said. "She also cut off his penis and flushed it down the toilet."

Yeung, a mainlander living in Hong Kong on a one-way permit, has admitted she killed Zhou - a two-way permit visitor - on Boxing Day 2012, but denied murder, saying she was provoked and suffered from depression.

Yeung told police in an interview shown in court yesterday that Zhou had beaten her and her four-year-old daughter because she refused to give him HK$200,000 to buy a car. He then stripped her and had forcible sex with her on the bed.

After the killing in a tiny public housing flat in Chai Wan, Yeung wrapped the body in a bed sheet and covered it with a mattress, the court heard.

The day after the killing, Yeung took her daughter to a Social Welfare Department centre where she wept and confessed she killed Zhou. "I cut it," Yeung told a social worker. "I think it was cruel. I did not mean it."
