In 2019, Drug Enforcement Administration agent Brady Wilson noticed big loads of synthetic drugs, like fentanyl, popping up around St. George, Utah. St. George is not exactly known as a hot spot for drugs; it’s a sleepy city of retirees, out-of-town hikers and Mormon churches. But Wilson had a gut feeling; he suspected a Mexican cartel had set up shop in town.

That would be the beginnings of Operation Sour Cream, a federal investigation into the origins of synthetic drugs in the St. George area.

Synthetic drugs have arrived in small cities and rural areas across the United States abruptly, with immediate, devastating impact. In Utah, fentanyl overdose deaths have increased 300 percent over a three-year period, killing 170 people in 2021, according to the state health department. Mexican criminal groups have become experts in producing fentanyl and meth across the border. Now, Wilson knew, they were honing their role in retail distribution in the United States, where synthetics had reshaped the geography of drug demand.

Today on “Post Reports,” Mexico City bureau chief Kevin Sieff reports on Wilson’s investigation into how fentanyl ended up in St. George, Utah, and what this increased presence of synthetic drugs means for the opioid crisis in the United States. This story is part of Cartel RX, an investigative series from The Post looking at the deadly fentanyl pipeline from Mexican labs to U.S. streets.
