RAPID CITY, SD (KELO) -- A federal judge on Friday sentenced a Rapid City man, tied to a Mexican drug cartel, to 25-years in prison.

38-year-old Guillermo Calderon pleaded guilty in March to Conspiracy to Distribute a Controlled Substance.

Prosecutors say Calderon was the leader of the conspiracy that trafficked significant amounts of methamphetamine to Rapid City and Pine Ridge from Mexican cartel operatives.

Authorities in Iowa arrested Calderon in January 2024, while he was allegedly driving 20-pounds of meth into South Dakota.
