“Fentanyl is one of the most lethal threats facing Maryland right now. As little as two milligrams of fentanyl can be a lethal dose, and the 20 kilograms of fentanyl seized in this case to date is enough to kill 10 million people — more than one and a half times the population of Maryland,” Maryland U.S. Attorney Robert K. Hur said in the release. “We are working with our partners to attack the sources of supply, as well as the street dealers who are committing the most violence in our neighborhoods.”
