On 16 May 2018 federal agents served search warrants on grow houses in Seattle, Burien, Kent, Tacoma and Renton in an Organized Crime Drug Enforcement Task Force investigation.[1] They seized more than 3,000 marijuana plants along with business records and equipment such as water tanks and grow lights.[1]

Agents arrested 37-year-old Seattle resident Xiamin Huang, and all three suspects, Huang, her husband Qifeng Li and his brother Qiwei Li, were charged with conspiracy to manufacture and distribute marijuana; the two men were still being sought.[1] Investigators said large wire transfers from China had paid for some of the 17 homes in the ring, whose marijuana was shipped to New York’s black market, and that one property alone ran up more than $37,000 in electricity bills in three months.[1]
