Eight Immortals Restaurant murders

On 4 August 1985, ten members of the Zheng family were murdered in the Eight Immortals Restaurant in Portuguese Macau. The perpetrator, Huang Zhiheng, had attacked the family at their business over unpaid gambling debts by restaurant owner Zheng Lin. After stabbing or strangling each of the victims to death, Huang dismembered their bodies and disposed of their remains in the ocean and dumpsters.

Huang was arrested in September 1986, over a year after the murders, having taken over and operated the Zheng family's restaurant during this time. He was convicted and sentenced to several prison terms the following month. Huang killed himself in prison only weeks after starting his sentence in December 1986.
