The Carroll County Sheriff’s Office says they helped shut down a meth lab in Silver Lake this past Wednesday. Carroll County Sheriff Domenic Richardi says the Sheriff’s Department and Madison Police Department acted on an investigation being conducted by the US Department of Justice’s Clandestine Laboratory Team and Organized Crime Drug Enforcement Task Force. They say sales of precursor pseudoephedrine (PSE) in Rochester, Farmington, and Ossipee areas led to Silver Lake-resident Daniel Helm’s residency. Helm had prior history of manufacturing drugs. Using a warrant, authorities found evidence of production of methamphetamine at 121 George Chick Drive. Evidence is currently being processed by State and Regional officials. Richardi says the investigation is currently ongoing.
