Millions of dollars worth of illegal drugs were seized by Riverside authorities last week-the culmination of a nearly year long investigation. The amount of drugs seized included 376 pounds of methamphetamine, 1.4 kilograms of cocaine, 37.4 pounds of fentanyl and 600,000 fentanyl tablets with the potential to provide ingredients for nearly 10 million lethal doses and were worth an estimated $16 million.
