Three men arrested in the largest methamphetamine seizure in Oregon have been convicted on drug and conspiracy charges. A federal jury returned guilty verdicts on all counts of a 10-count indictment against Octavio Mendoza-Morales, 36; Heriberto Montenegro-Mendez, 33; and Hector Villarruel-Lopez, 38. They were charged with conspiracy to distribute methamphetamine, heroin and cocaine, and various counts of possession. They were arrested after a 20-month investigation by the federal Drug Enforcement Administration and an Oregon interagency police team. The ringleader, Ricardo Mendoza-Morales, was recently sentenced to 25 years in prison following his guilty plea last summer. Prosecutors said more than 40 pounds of methamphetamine was seized. In addition, almost three kilograms of heroin, some cocaine, five vehicles with hidden compartments and $197,000 in cash were seized.
