Background

At approximately 3:00 a.m., a Portage County sheriff’s deputy followed a blue vehicle onto a narrow, unpaved dead-end road in a remote area. The deputy found that vehicle parked behind another occupied vehicle driven by Derek Lamb. The deputy had not observed a traffic violation, knew of no prior crimes on the road, and saw no interaction or suspicious activity between the vehicles’ occupants.

After the deputy approached in a marked squad car and shined a spotlight into Lamb’s vehicle, Lamb began driving forward. About two seconds later, the deputy moved his squad car in front of Lamb’s vehicle and activated its emergency lights. The ensuing stop led to the seizure of methamphetamine and drug paraphernalia.

The circuit court denied Lamb’s suppression motion, reasoning that the time, remote location, presence of two vehicles, and Lamb’s attempt to avoid contact supplied reasonable suspicion. Lamb then pleaded no contest to possessing methamphetamine as a repeat offender and appealed the resulting judgment.

The Court’s Holding

The Court of Appeals held that the State failed to establish reasonable suspicion that Lamb had committed, was committing, or was about to commit a crime. Although the reasonable-suspicion threshold is low, the deputy needed specific, articulable facts rather than a mere hunch. The lawful presence of two occupied vehicles on a remote dead-end road at 3:00 a.m. was insufficient, particularly because the area was not shown to be a high-crime location and the deputy identified no suspected crime, relevant training or experience, furtive conduct, interaction between occupants, or prior knowledge connecting Lamb or the vehicles to criminal activity.

The court further concluded that Lamb’s unhurried attempt to drive away was more akin to going about his business than flight. Because reasonable suspicion did not exist before Lamb attempted to leave, his exercise of the right to avoid police contact could not create it. Even if his conduct were characterized as flight, it did not tip the totality of the circumstances toward reasonable suspicion.

The court reversed the judgment and remanded with directions to vacate Lamb’s conviction and grant his motion to suppress the evidence obtained from the unlawful seizure.

Key Takeaways

  • Late-night presence in a remote location, without facts tying the conduct to a particular crime, does not by itself establish reasonable suspicion.
  • A person’s unhurried effort to avoid a consensual police encounter cannot create reasonable suspicion where none existed beforehand.
  • The State must identify specific, articulable facts supporting the stop; an officer’s curiosity or generalized sense that circumstances appear unusual is insufficient.

Why It Matters

The decision reinforces that lawful but unusual conduct does not automatically justify a Terry stop. Contextual factors such as the hour and location carry limited weight when officers observe no violation, criminal interaction, furtive movement, or other conduct reasonably suggesting that criminal activity is afoot.

It also draws an important line between headlong or dangerous flight and merely declining police contact. Officers generally may approach and investigate consensually, but a person’s decision to leave cannot retroactively supply the reasonable suspicion required for a seizure.
