evidence: "The availability of dangerous substances like fentanyl on dark net marketplaces is helping to fuel the crisis that has claimed far too many American lives," said FBI Director Christopher Wray. "That's why we will continue to join forces with our law enforcement partners around the globe to attack this problem together. The FBI is proud to stand with our domestic and foreign partners as we continue to shine that light into the deepest corners of the dark net and hold those accountable who continue to peddle this poison around the world." "The Sinaloa and Jalisco drug cartels, and the global networks they operate are killing Americans by sending fentanyl into the United States. Their associates distribute this fentanyl into communities across America by every means possible, including the dark web," said DEA Administrator Anne Milgram. "The DEA is committed to shutting down the fentanyl supply chain from beginning to end, and we will relentlessly pursue the associates of these cartels wherever they hide, even in the dark corners of the internet."
