In July 2012, the government decided to make a review of the mandatory death penalty applied to certain drug trafficking or murder offences. In the midst of this review, a moratorium was imposed on all the 35 pending executions in Singapore at that time (7 for murder and 28 for drug trafficking). During that period of the review of the mandatory death penalty, one convicted murderer named Pathip Selvan s/o Sugumaran (who made headlines for the violent murder of his 18-year-old girlfriend in 2008) won his appeal in October 2012 and was instead sentenced to 20 years' imprisonment for culpable homicide; a Chinese national named Wang Zhijian, the culprit of the 2008 high-profile Yishun triple murders case, was sentenced to death for a conviction of murder under Section 300(a) of the Penal Code in November 2012 (he is presumably executed since 2014 after the dismissal of his appeal), and another unnamed death row convict died of natural causes while in prison.
