(BENTON, IL) — On March 17, 2015, Daniel J. E. Overmyer, 23, of Carterville, IL, was sentenced for his involvement in a methamphetamine conspiracy, the United States Attorney for the Southern District of Illinois, Stephen R. Wigginton, announced Wednesday. Overmyer, who had previously pled guilty to the one-count indictment charging conspiracy to manufacture methamphetamine, was sentenced to 87 months in federal prison, to be followed by 3 years’ supervised release, and was $400. The offense occurred between 2010 and January 2014, in Jackson, Williamson, Union, and Franklin Counties. Evidence at the plea and sentencing hearings established that Overmyer was involved with others in the manufacture of methamphetamine. Overmyer and others purchased pseudoephedrine for others to use in the manufacture of methamphetamine. At sentencing, the district court found that Overmyer was responsible for the illegal possession of 180.06 grams of pseudoephedrine. Also, on March 17, 2015, two of Overmyer’s co-defendants, James C. Leming, 53, and Dawn E. Unterfer, 45, both of Carbondale, entered guilty pleas to the one-count methamphetamine indictment. Leming and Unterfer were allowed to remain on bond pending June 10, 2015, sentencing hearings. Six co-defendants have previously been sentenced for their involvement in the methamphetamine conspiracy. One co-defendant has pled guilty and is awaiting sentencing. Four co-defendants have pled not guilty and are awaiting jury trial. The ongoing investigation is being conducted by the Jackson County Sheriff’s Office, Murphysboro Police Department, Carbondale Police Department, Illinois State Police/Southern Illinois Drug Task Force, and Drug Enforcement Administration. The case is assigned to Assistant United States Attorney Amanda A. Robertson for prosecution.
