Thirteen people die and one is seriously injured in the Wah Mee massacre in Seattle. It is said to be the largest robbery-motivated mass-murder in U.S. history.

The Wah Mee massacre was a mass shooting that occurred during the night of February 18–19, 1983, in the Wah Mee gambling club at the Louisa Hotel in Seattle, Washington, United States. Fourteen people were bound, robbed and shot by three gunmen, 22-year-old Kwan Fai "Willie" Mak, 20-year old Keung Kin "Benjamin" Ng and 25-year-old Wai Chiu "Tony" Ng. Thirteen of the victims died, but 61-year-old Wai Yok Chin, a former U.S. Navy sailor and Pai Gow dealer at the Wah Mee, survived to testify against the three in the separate high-profile trials held between 1983 and 1985.
