Suppression of evidence is required when a vehicle is stopped for speeding and other infractions, but the officer extends the stop longer than necessary to deal with the offenses for which the stop was made. Mere nervousness and shaking of the Defendant’s hand, and refusal to consent to a search, were insufficient grounds to make the Defendant wait for a drug dog sniff. Hence, because the scope of the seizure was impermissible, the evidence had to be suppressed and the resulting OWI charge dismissed.
