(Portland, OR) -- A West Linn man has pleaded guilty to illegally importing and selling two-and-a-half million dollars worth of counterfeit N95 masks during the pandemic. Federal court documents show Jiang Yu worked with others to import the masks, market them online, and sell them. When customers asked about authenticity, they were sent fake certificates claiming they were N95 masks. At least two-and-a-half million dollars worth of masks were sold. As part of his plea agreement, Yu must pay restitution, forfeit 600-thousand counterfeit masks and surrender his 2004 Lamborghini, a Mercedes SUV, and more than 25-thousand dollars in cash.
