Dubuque Man Detained on Federal Firearms Charge after Using Drugs and Refusing to Take a Drug Test

For Immediate Release
U.S. Attorney's Office, Northern District of Iowa

Jeremy Michael Kieffer, 36, from Dubuque, Iowa, has been charged with one count of possessing a firearm while a marijuana user. ­ The charge is contained in an Indictment filed last month in United States District Court in Cedar Rapids.


The Indictment alleges that on November 7, 2016, Kieffer possessed a Glock Model 22 .40 caliber pistol. The Indictment further alleges that Kieffer was a marijuana user when he possessed the pistol. If convicted, Kieffer faces a possible maximum sentence of ten years’ imprisonment, a $250,000 fine, $100 in special assessments, and 3 years of supervised release following any imprisonment. ­


Kieffer was initially released pending his trial but was arrested last week after a drug test showed he was positive for methamphetamine. Following his arrest, a probation officer asked Kieffer for a urine sample, which he was required to provide pursuant to an order of a United States Magistrate Judge. Kieffer refused to provide a urine sample. Following yesterday’s detention hearing, the Court detained Kieffer pending his trial in April 2017.


As with any criminal case, a charge is merely an accusation and a defendant is presumed innocent until and unless proven guilty.


The case is being prosecuted by Assistant United States Attorney Tim Vavricek and was investigated by the Dubuque Police Department.
