A two year investigation into a Central Oregon drug trafficking ring has resulted in a half dozen arrests in Madras. Lieutenant Ken Mannix says it's believed this ring distributed large amounts of illegal drugs, mostly meth, throughout Central Oregon. “We do take comfort in knowing that just dismantled a fairly significant organization in the Central Oregon area. As much as I hate to say it; unfortunately when you dismantle one, another one pops up.”  Andres Garcia-Mendoza, 26, was working with five other coconspirators in dealing drugs.   Agents with the Drug Enforcement Administration and Alcohol Tobacco and Firearms were involved in the arrests. A pound of meth amphetamine, drug packaging material, firearms and cash were seized by police in last Thursday's arrest. One of the arrests occurred after two suspect vehicles were southbound on Highway 97 in Redmond.
