A Michigan man sells meth to an undercover agent and is sentenced to 18 months in prison. Jack R. Martin, of Iron Mountain, was charged with delivery of methamphetamine after selling $150 work of meth at a gas station in Little Suamico to an undercover officer. Oconto County District Attorney Edward Burke said Martin was extradited from Oklahoma where he will face prison after his sentencing here is completed. Once released Martin must maintain full time employment and absolute sobriety.
