The Wah Mee massacre (traditional Chinese: 華美大屠殺; simplified Chinese: 华美大屠杀; Jyutping: Wa4mei5 daai6tou4saat3; pinyin: Huáměi dàtúshā) was a multiple homicide that occurred during the night of February 18–19, 1983, in which Kwan Fai "Willie" Mak, Wai Chiu "Tony" Ng, and Keung Kin "Benjamin" Ng (no relation) bound, robbed, and shot fourteen people in the Wah Mee gambling club at the Louisa Hotel in Chinatown-International District, Seattle. Thirteen of their victims died, but Wai Chin, a dealer at the Wah Mee, survived to testify against the three in the separate high-profile trials held in 1983 and 1985. It is the deadliest mass murder in Washington state history.
