On November 20, 2022, Fang Hui Lin was working at a rural marijuana farm outside Hennessey, Oklahoma, when a dispute over money erupted into lethal violence. A male Chinese national of Asian descent, he was one of four workers at the isolated grow operation who would not survive the night, killed alongside three co-workers in what investigators would later describe as execution-style shootings.
The farm where Fang lived and worked sat on roughly ten acres of land in Kingfisher County, about a dozen miles from town, ringed by hoop houses and greenhouses that sheltered thousands of marijuana plants. Court and investigative records describe it as part of Oklahoma’s booming but increasingly lawless medical marijuana sector: a large, heavily developed site with more than a hundred grow structures, guarded access, and workers who slept in trailers, in the main house, or even in the garage where plants were stacked to dry. The operation’s license had been obtained through a local “straw” owner who fronted for out-of-state investors, and later investigations concluded the paperwork had been secured illegally, placing the farm squarely in the gray area between regulated agriculture and organized crime.
Into this tense environment stepped Wu Chen, also known in some records as Chen Wu, a mid-forties investor who had previously worked at the farm. Prosecutors later said he had put about $300,000 into the enterprise and had fallen into a bitter dispute with the people running it. On the evening of November 20, he arrived at the farm in a Toyota Corolla, went into one of the buildings around dusk, and gathered several workers into the garage area. What began as a confrontation over his money escalated quickly: witnesses told investigators that he demanded $300,000 in cash “on the spot” as a return on his investment, threatening to kill the workers if they could not produce it within half an hour. What they did have, by all accounts, were plants, tools, and a little cash—nowhere near the amount he was demanding.
Inside the garage, the situation deteriorated minute by minute. At some point during the standoff, Wu shot the farm’s boss in the leg, leaving him bleeding on the concrete floor while the others frantically tried to improvise a tourniquet with a long-sleeved shirt. The wounded man, realizing how dire his situation had become, reportedly told the gunman to “finish him off,” and Wu responded by firing twice into his chest. Panic then exploded into chaos: when two of the hostages rushed him in a desperate attempt to stop the attack, Wu unleashed a barrage of gunfire that cut down three more workers, including Fang and two of his colleagues. Another employee, Yi Fei Lin, was hit but survived, badly wounded, while a different worker fled and managed to leave a phone recording on near the garage, capturing the sound of gunshots and the killer’s departure into the night.
Outside, the November sky had gone completely dark by the time deputies were dispatched. Kingfisher County’s sheriff sent a mass text to his team shortly before 8 p.m., describing a possible hostage situation at the farm and urging everyone to rush to the scene. Responding officers arrived to an eerie, sprawling compound lit only by flashlights and the glow from scattered buildings. In the garage, they found four victims lying dead among stacks of marijuana; elsewhere, they discovered a wounded man collapsed in a black pickup and, later, another terrified worker hiding in a barn. The early moments of the investigation were dominated by fear that the shooter might still be somewhere amid the maze of greenhouses and outbuildings, turning the search for survivors into a manhunt conducted in pitch darkness.
The survivors quickly gave investigators a name. Using translation apps and hurried questioning at the scene and later at the hospital, deputies and state agents pieced together that the gunman was Wu Chen, a former worker and investor who had left the farm after arguing with his partners. With that identification in hand, the Oklahoma State Bureau of Investigation and other agencies issued a warrant and began tracing his escape route. According to court records and later news reports, Wu drove east immediately after the killings, heading across multiple states toward Florida and making calls along the way to contacts with ties to smuggling networks, apparently seeking help to flee the country.
Two days after the murders, license-plate readers in Miami Beach flagged the car he was driving, connecting it to the Oklahoma warrant. Local police moved in and arrested him without incident, finding themselves face-to-face with a man who, prosecutors alleged, had executed four people and tried to kill two others in a matter of minutes over a vanished investment. Extradited back to Oklahoma, he was charged in Kingfisher County with four counts of first-degree murder and one count of assault and battery with a deadly weapon. Prosecutors asked that he be held without bond, describing the killings as premeditated, execution-style murders, and citing eyewitness accounts and video evidence recorded by one of the fleeing workers.
In the months that followed, Fang’s name appeared in court documents and press accounts—often rendered as “Fang Hui Lee”—alongside those of the other three slain workers: Quirong Lin, a man in his forties; veteran grower Chen He Chun, who was about sixty; and another colleague, Chen He Qiang. Together they formed a small community of laborers who had come to Oklahoma for work and instead found themselves at the center of a crime that drew national and international attention. Their deaths were noted in memorial sites and news stories as a stark example of how the convergence of big money, lax regulation, and transnational criminal networks had turned parts of rural Oklahoma into a dangerous frontier.
On February 9, 2024, Wu Chen stood in a Kingfisher County courtroom and entered a guilty plea to all charges. Under the plea agreement and the judge’s ruling, he was sentenced to life in prison without the possibility of parole on each of the four murder counts, along with an additional sentence for assault with a deadly weapon, ensuring he will spend the rest of his life behind bars. Officials from the district attorney’s office and state investigative agencies later said the outcome brought a measure of justice for Fang and the other victims, even as they warned that the case underscored the lethal risks that had grown around Oklahoma’s illegal and illegally licensed marijuana operations.
Beyond the killer himself, the investigation rippled outward through the network that had allowed the farm to exist. The site’s nominal local owner was arrested soon after the shootings, and separate state and federal cases later targeted the alleged straw owner and an accountant tied to multiple marijuana operations, accusing them of helping to obtain licenses fraudulently and to move money and product through the black market. Those cases focused on financial and licensing crimes rather than homicide, but together with Wu’s conviction they painted a fuller picture of the world in which Fang had been working—a world in which the promise of quick profit collided with human lives, and where one night’s demand for $300,000 ended in four bodies on a garage floor and a life sentence handed down in a quiet Oklahoma courtroom.
