The Louisa Hotel had stood at the corner of South King Street and Maynard Avenue South since 1909, a fixture of Seattle's Chinatown. The building's history mirrored the neighborhood itself -- Prohibition-era murals would later be discovered on its walls, evidence of the layers of life that had played out within. The Wah Mee Club occupied the basement, one of several gambling establishments that operated semi-openly in the district. Patrons were mostly older Chinese American men, many of them members of the Bing Kung Tong, a fraternal organization with deep roots in the community. The club had a manager, a cook, and doormen who controlled access. On any given night, the stakes at the pai gow tables could be significant, and the three men who planned the robbery knew exactly how much cash circulated in that basement room.

The three perpetrators were Willie Mak, age 22; Benjamin Ng, age 20; and Tony Ng (no relation), age 25 -- all Hong Kong immigrants. Shortly before midnight on February 18th, Mak and Tony Ng entered the club and lingered at the bar on the upper level. Around 12:30 AM, Benjamin Ng arrived carrying a paper bag with pre-cut nylon cords inside. The three men drew their weapons, ordered everyone to the ground, bound them, and robbed the club. Then, in an act of calculated brutality meant to eliminate all witnesses, they shot every person in the room. Among the thirteen killed were restaurateur Moo Min Mar and his wife Jean Bick Chinn, a retired postal worker, a fishmonger, cooks, a theater projectionist, and a former Army sergeant. But one man survived. Wai Yok Chin, a 61-year-old pai gow dealer and former Navy sailor, had been shot but played dead. He would become the prosecution's key witness.

Mak and Benjamin Ng were arrested almost immediately. Mak confessed, declaring he had "shot them all" -- a statement he later recanted. Tony Ng fled, evading capture for twenty months before the Royal Canadian Mounted Police arrested him in Calgary, Alberta, where he had been living under the alias Jim Wong and working as an electronics technician. The trials drew national attention. Benjamin Ng was convicted of thirteen counts of aggravated first-degree murder and sentenced to life without parole. Willie Mak was initially sentenced to death by hanging, but the Washington State Supreme Court later ruled the 1983 jury had not properly assessed his role, and he was resentenced to life without parole. Tony Ng was acquitted of murder but convicted of thirteen counts of first-degree robbery and one count of assault, receiving a combined sentence of thirteen life terms totaling 35 years. He was paroled in 2013 and deported to Hong Kong the following year.

The massacre devastated Seattle's Chinese American community in ways that extended far beyond the immediate grief. The Wah Mee Club was part of a social fabric -- the gambling dens, whatever their legal status, were gathering places for an immigrant generation that had built lives in a neighborhood shaped by decades of exclusion laws and discrimination. The crime reinforced painful stereotypes and drew unwanted scrutiny to Chinatown's internal affairs. Families who had lost fathers, husbands, and brothers found themselves navigating a justice system that stretched across decades. Relatives of victims spoke at parole hearings as late as 2009, expressing outrage that Tony Ng was nearing release. The Louisa Hotel itself suffered a devastating fire in December 2013, though owners later preserved the exterior and converted the building into apartments, which opened in 2019. The Wah Mee Club space remains sealed, a silent memorial to the thirteen lives taken on that February night.
