The case involved a vehicle stop for a minor traffic violation committed in the presence of the highway patrol officer. The stop resulted ultimately in an arrest for possession of unlawful drugs. However, the circuit court upheld the district court decision, because the police officer acted within the scope of legal limitations until probable cause existed to justify a formal arrest. The detention for 1 hour was determined to be reasonable in this case and did not rise to the level of a de facto arrest; the police officers accommodated the suspect's request to leave the site of the initial stop and respected his freedom of movement and privacy, using the last intrusive means of detention reasonably necessary to achieve the investigative purpose.
