GROVES et al.
v.
The STATE.
No. A10A1499.
Court of Appeals of Georgia.
November 15, 2010.
Catherine S. Bernard, for appellants.
L. Craig Fraser, Dublin, Lashonda C. Harris, for appellee.
*372 DOYLE, Judge.
In this interlocutory appeal, Curtis Groves and David Smith challenge the denial of their motions to suppress evidence obtained by an officer during a traffic stop. Because the officer executed the traffic stop without the suspicion required to justify such a stop under the Fourth Amendment of the United States Constitution, we reverse.
On appeal from a motion to suppress, the evidence is viewed in a light most favorable to upholding the trial court's judgment. The credibility of witnesses and the weight accorded their testimony rest with the trier of fact. Thus, the trial court's findings on disputed facts and credibility must be accepted unless clearly erroneous. Where the evidence is uncontroverted and there is no issue as to witness credibility, however, we review de novo the trial court's application of the law to the undisputed facts.[1]
In this case, the relevant facts are not in dispute. The record shows that an officer on patrol spotted a lone sedan parked at the edge of an otherwise empty parking lot at a truck plaza. The officer pulled his marked patrol car behind the car and noticed that it was occupied by a passenger, Smith, and a driver, Groves, who was leaning briefly into the passenger side. Neither occupant noticed the officer, and approximately one and a half minutes elapsed as the officer called in the tag number. Groves then looked up, noticed the patrol car in his rear view mirror, put his car into gear, and "continued to drive on." The officer immediately activated his emergency lights and executed a traffic stop of the vehicle.
After the car stopped, the officer spoke to the occupants, noticed the smell of alcohol coming from Groves, obtained consent to search the car, and discovered what turned out to be crushed oxycodone packaged in cellophane in the car's glove box. Based on the contraband, Groves and Smith were arrested and charged with one count of possession of oxycodone in violation of the Georgia Controlled Substances Act.[2] The two defendants unsuccessfully moved to suppress the evidence from the stop, and this Court granted their application for interlocutory appeal.
Groves and Smith argue that the trial court erred by concluding that the officer's initial traffic stop was justified and by ruling that the evidence obtained during the stop was therefore admissible. We agree.
According to Terry v. Ohio,[3] police-citizen encounters are generally categorized into three tiers: consensual encounters; brief investigatory stops, which require reasonable suspicion; and arrests that must be supported by probable cause. In a first-tier encounter, police officers may approach citizens, ask for identification, and freely question the citizen without any basis or belief that the citizen is involved in criminal activity, as long as the officers do not detain the citizen or create the impression that the citizen may not leave.... So long as a reasonable person would feel free to disregard the police and go about his business, the encounter is consensual and no reasonable suspicion is required.[4]
As an initial matter, we note that "[t]he actions of an officer approaching a stopped vehicle, requesting to see a driver's license, and inquiring about possible criminal or suspicious activity clearly fall within the realm of the first type of police-citizen encounter and do not amount to a stop" implicating Fourth Amendment concerns.[5] Thus, before Groves pulled away, while the officer merely sat in his patrol car behind Groves's stopped vehicle, the encounter had not yet risen beyond a consensual, first-tier encounter requiring no suspicion. Therefore, Groves was free to ignore the officer and *373 leave if he chose.[6]
However, after Groves began to pull away, the officer activated his emergency lights, executed a traffic stop, and asked Groves for his identification. This escalated the encounter to a second-tier Terry stop,[7] because the officer's intention was undisputably to stop Groves from driving away.[8]
During a second-tier encounter, ... a police officer, even in the absence of probable cause, may stop persons and detain them briefly, when the officer has a particularized and objective basis for suspecting the persons are involved in criminal activity. To stop a citizen, the officer must possess more than a subjective, unparticularized suspicion or hunch. The officer's action must be justified by specific and articulable facts which, taken together with rational inferences from those facts, reasonably warrant that intrusion, and the officer must have some basis from which the court can determine that the detention was neither arbitrary nor harassing.[9]
Here, the officer testified at the suppression hearing that the car seemed "extremely out of place" in the empty truck plaza parking lot, but he had no other reason to suspect any criminal activity. Nevertheless, despite having no "specific and articulable facts" supporting a suspicion of criminal activity, the officer conducted "a traffic stop as soon as the driver put the vehicle into gear and went to leave the scene." Such stops are unauthorized.[10] That the car was "out of place" perhaps gave rise to a generalized suspicion or hunch, but in the absence of other circumstances, Groves's mere presence in an empty truck plaza parking lot was not sufficient to warrant a traffic stop.[11]
This evidence simply did not constitute an objective manifestation that [Groves and Smith were], or [were] about to be, engaged in criminal activity sufficient to warrant the intrusion of a traffic stop. While such behavior might justify an officer in closely observing the individual[s] engaged in that behavior, it is not alone sufficient to indicate that the individual[s] [are] or might be engaged in illegal activity so as to provide a reasonable, articulable suspicion to stop [those] individual[s].[12]
Moreover, Groves's actions prior to the stopputting the car into gear and proceeding on his waywere not sufficient to justify the stop, because at that point the encounter was a consensual, first-tier encounter, and Groves was entitled "to exercise his right to ignore the police and to leave. Indeed, a citizen's ability to walk away from or otherwise avoid a police officer is the *374 touchstone of a first-tier encounter."[13] "Such conduct may not provide the basis for elevating the encounter to a second-tier Terry stop."[14]
In light of our conclusion, the oxycodone at issue in this case was inadmissible because it was discovered pursuant to consent that was the product of an unauthorized traffic stop.[15] Likewise, the smell of alcohol about Groves's person did not authorize further investigation or detention because it was observed during the unauthorized traffic stop.[16] Accordingly, we reverse the trial court's denial of the defendants' motions to suppress.
Judgment reversed.
ANDREWS, P.J., and ELLINGTON, J., concur.
