Over 1,000 pounds of methamphetamine was seized in Colorado during an operation to take down a drug ring with connections to Mexico.
The details of the seizures were released as part of a 15-person federal grand jury indictment announced Wednesday by the U.S. Attorney for the District of Colorado, which said it marks the largest meth seizure in state history.
Eleven of the 15 individuals indicted are in custody, while the other four are thought to be somewhere in Mexico, according to the U.S. Attorney’s Office. All the defendants face drug charges, while four also face money laundering charges.
