During the early morning hours of February 19, 1983, three armed men entered the Wah Mee Club, an illegal gambling parlor in the basement of the Louisa Hotel at 665 South King Street in Seattle's Chinatown-International District. The club, known within the community for high-stakes gambling, was frequented by patrons carrying large sums of cash. The gunmen, admitted as regulars, gained entry near closing time and proceeded to bind the occupants at gunpoint before robbing them.

The attackers hogtied fourteen people with nylon cord and shot each of them, most in the head and some repeatedly, in what investigators concluded was a deliberate attempt to leave no witnesses. Thirteen victims died, making it the deadliest mass murder in Washington state history. The dead ranged in age and included gamblers, club employees, and community members; the killings devastated the tight-knit Chinatown-International District.

One man survived. Wai Yok Chin, a 61-year-old pai gow dealer and former U.S. Navy sailor, was shot but managed to loosen his bindings, crawl up the stairs, and reach South King Street, where he flagged down help and alerted police. Despite his wounds, Chin lived to identify the assailants and became the prosecution's central eyewitness across the trials. He died in May 1993 at age 71.

Police quickly identified three suspects: Kwan Fai "Willie" Mak, 22; Keung Kin "Benjamin" Ng, 20; and Wai Chiu "Tony" Ng, 25 (no relation to Benjamin). Investigators concluded the robbery was primarily planned by Mak, reportedly to pay off gambling debts. Mak and Benjamin Ng were arrested in Seattle within days. Tony Ng fled the country and remained a fugitive until he was arrested in Calgary, Alberta, Canada, on October 4, 1984, and later extradited.

All three men were convicted, but their outcomes differed significantly. Benjamin Ng was convicted on August 25, 1983, of 13 counts of aggravated first-degree murder; jurors declined to impose death, and he was sentenced the following day to life in prison without the possibility of parole. Willie Mak was convicted on October 6, 1983, and sentenced on October 22 to death by hanging. His death sentence was overturned on appeal in 1988 due to flawed sentencing-phase instructions, and after further proceedings he was resentenced on April 29, 2002, to life in prison without parole.

Tony Ng, whose defense argued he participated under duress from Mak and did not fire the fatal shots, was tried separately in 1985. On April 19, 1985, a jury found him guilty of 13 counts of first-degree robbery and one count of first-degree assault, but acquitted him of the murder charges. He was sentenced on July 3, 1985, to consecutive terms totaling a lengthy prison sentence with the possibility of parole.

As of the most recent reporting, both Willie Mak and Benjamin Ng remain incarcerated in Washington state, serving life sentences without parole. Tony Ng was granted parole in October 2013 after serving roughly 28 years and was deported to his native Hong Kong on May 13, 2014. The massacre remains a defining tragedy in the history of Seattle's Chinatown-International District, memorialized on its anniversaries.
