Forty-eight alleged drug traffickers and violators from San Angelo and the surrounding areas have been arrested as part of an 18-month-long narcotics operation, announced United States Attorney for the Northern District of Texas Ryan Raybould at a press conference in San Angelo, Texas today.

“This message should send a loud and clear message to drug dealers in the Concho Valley.  We are coming for you,” said U.S. Attorney Ryan Raybould.  “This operation is proof of concept for state, local, and federal agents coming together to dismantle an alleged drug trafficking network.  As U.S. Attorney, I will put more time, attention, and resources into ensuring that the Concho Valley is safe.”

“Operation Concho Valley was a decisive, collaborative effort. By combining resources and expertise, we dismantled this drug trafficking organization and removed a dangerous presence that had cast a shadow over West Texas communities. These drugs fuel addiction, breed violence, and destroy families. The network we targeted was importing large quantities of methamphetamine, cocaine, heroin, and lethal fentanyl — substances that threaten public safety and the quality of life for residents,” said DEA San Antonio Division Special Agent in Charge Miguel Madrigal.

Twenty-four of the alleged drug dealers were federally indicted on May 13, 2026, and were arrested following a large-scale drug bust in San Angelo last week.  Another 24 alleged violators were charged by local district attorneys on felony and misdemeanor offenses related to the operation.
