Based upon the information contained therein, your Complainant believes the following to be true and correct: That at approximately 12:59 A.M. On September 28, 2025, Officer Rinzel was working a Towards Zero Death (TZD) detail traveling 80th Street in the City of Cottage Grove, Washington County, Minnesota, when he observed a motor vehicle eastbound 80th Street without a front license plate. Officer Rinzel caught up to the suspect motor vehicle and initiated a traffic stop. Once stopped Officer Rinzel approached and observed a male driver along with three male passengers.
Officer Rinzel identified the driver via a Minnesota identification card as one JOSEPH DAVID SLYMAN, hereinafter referred to as “the Defendant.” The Defendant admitted that he did not have a valid driver’s license and that his status was currently “revoked”. The Defendant also admitted that he was in the process of taking his passengers home and that they were coming from the Muddy Cow bar. During his contact with the Defendant Officer Rinzel observed the Defendant’s motor movements to be slow and deliberate, his eyes to be bloodshot and glossy and his pupils to be constricted.
Officer Rinzel returned to his squad and ran the Defendant. Officer Rinzel confirmed that the Defendant was “revoked” in Minnesota. When another Officer arrived on scene Officer Rinzel re-approached the suspect motor vehicle and asked the Defendant to step from the vehicle to perform roadside field sobriety testing. The Defendant agreed and performed poorly on a series of field tests and then tested.000 on a digital PBT. The Defendant denied taking any prescribed medication and indicated to Officer Rinzel that he didn’t want to talk about any possible drug use.
Based on his observation of the Defendant and the Defendant’s performance on field sobriety testing Officer Rinzel believed the Defendant was under the influence of a controlled substance. The Defendant was placed under arrest for DWI. Officer Rinzel transported the Defendant to the Cottage Grove Police Department. Upon arrival Officer Rinzel led the Defendant into the booking room. Officer Rinzel made an application for a search warrant for a fluid test. That warrant request was reviewed and signed by the Honorable Laura Pietan, Judge of District Court.
The signed warrant was to the Defendant who stated that he did not want to “be poked by a needle” but that he would agree to provide a urine sample. Officer Rinzel retrieved a urine kit and then supervised the collection of the Defendant’s urine sample. This sample was then sealed and mailed to the Bureau of Criminal Apprehension (BCA) laboratory for analysis. Your Complainant has been advised by RoseMarina Siegfreid and Julia Liebl and Jennifer Setterstrom, both Forensic Scientists with the BCA, that analysis of the Defendant’s urine sample revealed the presence of cocaine, benzoylecgonine, codeine, hydromorphone and morphine, all are Schedule II controlled substances.
