The Department of Justice (DOJ) declined to prosecute Massachusetts-based biochemical company MilliporeSigma for its “extraordinary cooperation” in uncovering a “rogue” employee’s scheme to procure and ship discounted products to China using falsified export documents.

Gregory Muñoz, a MilliporeSigma salesperson, and his accomplice, Ben Yu, pleaded guilty to one count each of wire fraud conspiracy for their roles in the scheme, the DOJ announced in a press release Wednesday.
