Warren County, Iowa. Recently it was determined that Officer Devin Thomas from the Indianola Police Department had not previously been certified through the Iowa Law Enforcement Academy to conduct OWI investigations including administering field sobriety tests, invoking implied consent, or operate the Datamaster. Nevertheless, he engaged in an OWI investigation and subsequent arrest of a GRL client including having him submit to a breath test despite not being certified. This lack of certification came to light at the administrative DOT hearing and a subsequent motion to suppress was filed in the criminal matter. As a result all evidence of the OWI investigation was thrown out and the charge was ultimately dismissed.
