Last week three area residents were charged with possession of cocaine, and this follows a rising trend of cocaine-related arrests being seen in Knoxville. That’s according to Knoxville Police Chief Dan Losada. Pella Police Chief Michael Marcinkowski says his officers have not made any cocaine-related arrests, but both Losada and Marcinkowski say their departments continue to deal with users of methamphetamine. An undercover narcotics deputy with the Marion County Sheriff’s Office told KNIA/KRLS News that prescription drug and meth use are still more common than cocaine.
