The killings were placed in Shenzhen, in Guangdong province, between 1999 and 2003. Four of the eleven victims were women and seven were men. At the opening of the hearing in March 2008 Wu said he had acted either for money or in anger, and he was sentenced to death.
The source is a single Xinhua News Agency dispatch of March 20, 2008. Chinese courts do not publish judgments in cases of this kind, no execution has been reported, no victim is named, and the method of killing is not recorded, so none is given here.
The figure of eleven rests on what Wu said at the opening of his own hearing, not on any published evidence, and it stands as a count he announced rather than one a court is known to have set out.
