Before STEELE, Chief Justice, JACOBS, and RIDGELY, Justices.

Opinion:
RIDGELY, Justice:
Defendant-Appellant Jose Lopez-Vazquez appeals his convictions, following a Superior Court jury trial, of various drug charges. He argues that the trial judge erred in denying his motion to suppress evidence found as a result of what he asserts was an illegal 'stop that violated his Fourth Amendment rights. Specifically, Lopez-Vazquez contends that the police lacked reasonable suspicion to seize him when they did, thereby tainting the subsequent consent he gave to a search of his vehicle that resulted in the seizure of cocaine. We conclude that the Superior Court erred in denying the motion to suppress. Accordingly, we reverse.
I. Facts
Detective Hector Cuadrado received a tip from a past-proven reliable confidential informant that "Popi Chulu," later identified as Julio Polanco-Lugo, was selling drugs in the city of Wilmington, Delaware. Police began to mount an investigation of Polanco-Lugo, including setting up two controlled purchases. After the first controlled purchase, police observed the seller and followed his Dodge Caravan as the seller met with other subjects and engaged in what police believed were other drug sales. They also followed the car back to the 3900 block of Lancaster Avenue, Lancaster Court Apartments, where they saw the driver enter Building 3914, an multi-unit apartment building.
Eleven days later, police set up a second controlled purchase. During surveillance at 3914 Lancaster Avenue, police observed the same Dodge Caravan parked in front of the apartment building. They also observed a green Dodge Stratus pull in front of 3914 Lancaster Avenue and park. Detective Cunningham, who had seen the seller during the first controlled buy, noted that the driver of the Dodge Stratus was the same person (Polanco-Lugo). Detective Cunningham set up a second controlled purchase and went to meet the seller. Detective Cuadrado remained behind, and saw Polanco-Lugo get into the Dodge Stratus. Although Detective Cua-drado began to follow Polanco-Lugo, Detective Cunningham told him to return to set up surveillance at 3914 Lancaster Avenue.
After Detective Cuadrado set up surveillance, he saw a green Saab pull up and park on the southeast corner of Court Drive and Lancaster Avenue. The driver of this car, later identified as Lopez-Vazquez, walked over to and stopped in front of 3914 Lancaster Avenue. Lopez-Vazquez was unknown to the police and was not a target of the investigation. Detective Cuadrado watched Lopez-Vazquez talk for about fifteen minutes with another man, who had independently arrived on the scene, while standing in front of the steps of the front entranceway of the apartment building. That man was Michael Hernandez, who Detective Cuadrado recognized as a subject of an unrelated drug investigation. Based on his experience in drug investigations, Detective Cua-drado testified that the two men appeared to be nervous and anxious, and waiting for someone to return. Dispatch then informed the detective that the driver of the Dodge Stratus was headed back to the Lancaster Court Apartments.
Detective Cuadrado testified that after the Dodge Stratus arrived and parked, Lopez-Vazquez and Hernandez reacted in a way that led him to believe that the driver was the person for whom the men had been waiting. He saw Polanco-Lugo approach Hernandez and Lopez-Vazquez. Hernandez was positioned on the front step of the building, and Lopez-Vazquez was on the ground level. Polanco-Lugo threw the keys "up high" toward Hernandez (who caught them), and then walked away from them. Polanco-Lugo did not speak to Lopez-Vazquez or acknowledge his presence. Hernandez walked into the building. Lopez-Vazquez entered the building after Hernandez. Because they disappeared from sight, Detective Cuadra-do explained that he was unable to tell where each went after entering the building. Polanco-Lugo walked into the same building about five minutes later.
While Detective Cuadrado was making these observations, Detective Cunningham had applied for and obtained a search warrant for Polanco-Lugo's apartment. The team arrived to execute the search warrant about an hour after Hernandez and Lopez-Vazquez entered the building. Meanwhile, but after the search warrant had been executed, another officer told Detective Cuadrado that he saw Lopez-Vazquez coming out of the rear of the building and was heading toward the Saab. Detective Cuadrado radioed Detective Silva, who had just arrived on the scene, to approach Lopez-Vazquez and ask what his business was with Polanco-Lugo, since Lopez-Vazquez had been observed with some of the targets that he was investigating.
Detective Silva testified that he walked up to Lopez-Vazquez and asked Lopez-Vazquez if he would speak with him. When Detective Silva did not get an an swer, he thought Lopez-Vazquez might speak Spanish, and asked him in Spanish whether he would speak to him. Lopez-Vazquez answered "Sure." They then engaged in a conversation about where Lopez-Vazquez was coming from and what was his name.
Detective Silva testified that Lopez-Vazquez acted nervously during this encounter. Lopez-Vazquez told the detective that he was coming from his apartment, but could not tell him what his apartment number was. He also had his hands in his pocket, which prompted Detective Silva to ask him to take out his hands for safety purposes. When Lopez-Vazquez did that, the detective saw that he had a set of keys with a Saab emblem on them. Although Detective Silva knew that Lopez-Vazquez was facing the green Saab, he asked him whether his car was in that area. Lopez-Vazquez told him that it was, looked at the green Saab, but then pointed toward a different location.
Detective Silva then asked Lopez-Vazquez if he had anything in his possession and whether he could search him. Lopez-Vazquez told Detective Silva that he did not, and then consented to a search. Detective Silva found some money wrapped in plastic, although the significance of this fact was not explained. Based on his answers, demeanor, and the money being plastic-wrapped, Detective Silva testified that he placed Lopez-Vazquez "under arrest, or detained him." He then asked Lopez-Vazquez, who was facing the green Saab, "Are you sure that the car that you're talking about is not the one that you're looking at?" Lopez-Vazquez "lowered his head" and answered yes. When Detective Silva asked if there was anything in that car, Lopez-Vazquez answered "No, there's nothing." He then consented to Detective Silva's request to search the vehicle. A police canine was brought to the scene and provided a positive indication for the presence of drugs in the Saab. The vehicle was towed, and when later searched pursuant to a warrant, police found cocaine in a hidden compartment.
Lopez-Vazquez filed a motion to suppress, claiming that the police did not possess a reasonable and articulable suspicion that he was engaged in criminal activity. In response, the State argued that "the veteran detectives in this case conducted a valid Terry stop that was followed by a valid consent by the defendant." The State conceded that Detective Silva had "seized" Lopez-Vazquez during the initial encounter, which raised the issue of whether the detective had reasonable and articu-lable suspicion to detain him at that point. In a bench ruling, and without the benefit of a transcript, the trial judge denied Lopez-Vazquez's motion. A Superior Court jury convicted him of Trafficking in Cocaine, Possession with Intent to Deliver and Use of a Vehicle for Keeping a Controlled Substance. After sentencing, Lopez-Vazquez filed this appeal.
II. Discussion
A. Standard of review on motions to suppress
On appeal, Lopez-Vazquez argues that the trial judge erred in denying his motion to suppress. We review the grant or denial of a motion to suppress for an abuse of discretion. To the extent that we examine the trial judge's legal conclusions, we review the trial judge's determinations de novo for errors in formulating or applying legal precepts. To the extent the trial judge's decision is based on factual findings, we review for whether the trial judge abused his or her discretion in determining whether there was sufficient evidence to support the findings and whether those findings were clearly erroneous. Where as here, we are reviewing the denial of motion to suppress evidence based on an allegedly illegal stop and seizure, we conduct a de novo review to determine whether the totality of the circumstances, in light of the trial judge's factual findings, support a reasonable and articulable suspicion for the stop.
B. Review standard for when a stop takes place and the determination of reasonable suspicion
Determining whether an officer had reasonable and articulable suspicion to conduct the stop requires a threshold finding of when the stop actually took place. "Under the Fourth Amendment to the United States Constitution, a seizure requires either physical force or submission to assertion of authority." Once the point at which the stop or seizure occurred has been determined (the Terry stop), we examine whether at that point the police had a reasonable and articulable suspicion that criminal activity was taking place. Like probable cause,- reasonable suspicion is an "elusive concept" , but requires "some objective manifestation that the person stopped is, or is about to be, engaged in criminal activity." In determining whether a Terry stop was supported by reasonable suspicion, the courts consider the totality of the circumstances known to the officer at the time of the stop.
To meet this standard and establish the reasonable and articulable suspicion necessary to survive a motion to suppress, the State must show specific facts "which, when taken together with rational inferences from those facts, reasonably warrant" the stop. Consistent with federal law, we have adopted a two-pronged analysis when assessing the officer's articulation of the facts and his conduct. First, the court must assess the "objective observations and consideration of the modes or patterns of operation of certain kinds of lawbreakers." Second, the court "must consider the inferences and deductions that a trained officer could make which might well elude an untrained person."
The analysis of these factors is not done in isolation. Nevertheless, it is "possible for factors, although insufficient individually, to add up to reasonable suspicion — that is the nature of a totality of the circumstances test. But we think it impossible for a combination of wholly innocent factors to combine into a suspicious conglomeration unless there are concrete reasons for such an interpretation." This Court has consistently explained that a determination of reasonable suspicion must be evaluated in the context of the totality of the circumstances to assess whether the detaining officer had a particularized and objective basis to suspect criminal activity. The totality of the circumstances must be viewed through the eyes of a reasonable, trained police officer in the same or similar circumstances, combining objective facts with the officer's subjective interpretation of those facts.
A finding of reasonable suspicion is both "somewhat abstract" and "fact specific" and depends on the "concrete factual circumstances of individual cases." 'While the police may properly employ hunches to investigate, more is required to detain a citizen in a public place." Put another way, standing alone, an officer's "subjective impressions or hunches" are insufficient for a stop. Similarly, activity such as "leaving the scene upon the ap proach, or the sighting, of a police officer" or the "refusal to cooperate with an officer who initiates an encounter" cannot be the sole grounds constituting reasonable suspicion. These events, however, may be considered as part of the totality of the circumstances. Other circumstances may also be considered, such as the presence of a defendant in a high crime area, the defendant's "unprovoked, headlong flight," a defendant "holding a bulge in his pocket that appeared to be either a gun or a large quantity of drugs" , a "focused" warning shout of police presence, or a furtive gesture after the officer's approach or display of authority. The officer's subjective interpretations and explanations of why these activities, based on experience and training, may have given him a reasonable suspicion to investigate further are also important, as is the trial judge's evaluation of the officer's credibility. With these principles in mind, we evaluate whether there was a reasonable and artic-ulable suspicion to seize Lopez-Vazquez.
C. There was no reasonable and articulable suspicion
At the suppression hearing, the State rested its argument on its contention that "the veteran detectives in this case conducted a valid Tetry stop that was followed by a valid consent by the defendant." Before both the Superior Court and this Court, the State agreed with the defense that Lopez-Vazquez was "seized" for all relevant purposes when Detective Silva asked if he could speak to him. The doctrine of waiver applies equally to the State as it does to a defendant. Thus, any argument that Detective Silva initiated a consensual encounter has been waived. Therefore, we are left to determine whether at the point the agreed-upon seizure took place (that is, when Detective Silva approached Lopez-Vazquez), the totality of the circumstances supported the conclusion that the police had reasonable suspicion that Lopez-Vazquez was engaged in criminal activity. We find that they did not.
A review of the record shows that the following events had taken place prior to Detective Silva's approach. Lopez-Vazquez was not known to the police nor was a subject of their investigation of Po-lanco-Lugo. He had pulled up in a green Saab in front of an apartment building at the same time the police were investigating Polanco-Lugo for drug activity, but after Polanco-Lugo had left the scene. Lopez-Vazquez spoke to Hernandez, a second but unrelated drug suspect, for approximately fifteen minutes. Both Lopez-Vazquez and Hernandez appeared nervous and anxious, behavior which the observing officer considered to be consistent with waiting for someone. But when Polanco-Lugo, the target of the drug investigation, returned, he threw a set of keys specifically to Hernandez before walking away. Contrary to the officer's suggestion that Lopez-Vazquez was waiting for someone, Polanco-Lugo did not speak to Lopez-Vazquez or even acknowledge his presence. Although Lopez-Vazquez entered the building after Hernandez, there is no evidence of where he went or that he was accompanying Hernandez. An hour later, Lopez-Vazquez was seen outside of the building alone.
In its bench ruling, the Superior Court made two factual findings that we must specifically address: (1) the police observed Lopez-Vazquez "make a contact" with Polanco-Lugo and (2) their surveillance revealed that Lopez-Vazquez had met with Polanco-Lugo in Polanco-Lugo's apartment. The parties have not shown us, nor have we found, any evidence in the record supporting these findings. To the contrary, Hernandez, not Lopez-Vazquez, was the one observed to "make a contact" with Polanco-Lugo when Polanco-Lugo threw his keys at him. The only later surveillance of Lopez-Vazquez involved seeing him outside the apartment building, not inside it. Because these additional findings are clearly erroneous, they cannot be used to support a finding of reasonable suspicion. Therefore, we must determine whether the remaining factual findings give rise to reasonable suspicion at the time of the stop.
The observed nervous behavior by an unknown person standing next to and conversing with a known drug suspect gave police a "hunch" that the unknown person might be involved with the target of their investigation. Nothing in the record, however, provides concrete reasons why the remainder of the wholly innocent events that occurred before the seizure (for example, entering into a multi-unit apartment building after Hernandez, spotting Lopez-Vazquez outside of the building — and alone — an hour later by himself) combine into a "suspicious conglomeration" which supports a Terry stop. We do not find the totality of the circumstances to give rise to the requisite reasonable and articulable suspicion of criminal activity by Lopez-Vazquez required under Terry to justify seizing him.
D. Consent is tainted by the illegal seizure
The absence of a reasonable basis for a Fourth Amendment seizure bears directly upon the validity of Lopez-Vazquez's subsequent consent to search. "If consent is given after an illegal seizure, that prior illegality taints the consent to search" because the primary purpose of the federal exclusionary rule is to deter future unlawful police conduct and safeguard constitutional rights. Notwith standing this purpose, taint may be purged and the evidence may be admissible through one of the doctrinal exceptions to the exclusionary rule, such as the independent source doctrine, the inevitable discovery doctrine, the exigent circumstances doctrine, and the attenuation doctrine.
The attenuation doctrine exception permits courts to find that the poisonous taint of an unlawful search and seizure has dissipated when the causal connection between the unlawful police conduct and the acquisition of the challenged evidence becomes sufficiently attenuated. Thus, even if there is an illegal search or seizure, direct or derivative evidence, such as consent, may still be admissible if the taint is sufficiently "purged." In Brown v. Illinois, the United States Supreme Court explained that courts should consider three factors when determining whether evidence that is impermissibly obtained may be sufficiently purged of the primary taint and admitted through the attenuation doctrine: (1) the temporal proximity of the illegality and the acquisition of the evidence to which the instant objection is made; (2) the presence of intervening circumstances; and (3) the purpose and flagrancy of the official conduct. No "single factor" is dispositive in determining whether the evidence should be suppressed.
Applying these attenuation factors in this case, the record does not demonstrate that Lopez-Vazquez's consent was purged of the primary taint. The consent occurred during an illegal seizure. There were no intervening circumstances that would have provided independent probable cause or would otherwise have operated to dissipate the primary taint. These two considerations outweigh the fact that Detective Silva's conduct in asking for consent was neither egregious nor a flagrant abuse of police power. Accordingly, the evidence that was obtained following the invalid Terry stop must be suppressed as fruit of the poisonous tree. The Superior Court should have granted Lopez-Vazquez's motion to suppress.
III. Conclusion
The judgment of the Superior Court is REVERSED and this matter is RE MANDED for further proceedings consistent with this Opinion.

.Neither before the Superior Court, nor before this Court did any party argue that the police had reasonable and articulable suspicion to stop Lopez-Vazquez because he was a companion of Hernandez. In examining the "automatic companion" rule under current federal law, the Superior Court has determined the rule has been defunct under federal law since Ybarra v. Illinois, 444 U.S. 85, 100 S.Ct. 338, 62 L.Ed.2d 238 (1979), and at least four circuits have since rejected it. See State v. Henderson, 906 A.2d 232, 236-37 (Del.Super.Ct.2005) (citing cases and also noting that the Third Circuit and the District Court of Delaware had not weighed in on it), aff'd on alternate grounds, 892 A.2d 1061 (Del.2006). The Superior Court rejected the automatic companion rule as a matter of state constitutional law and noted that the automatic companion rule would run counter to the underlying principles of the totality of the circumstances approach used for stops. See id. at 238-46, see also id. (appendix to opinion) at 246-48. This Court has not decided the issue, and we will not do so here. See State v. Henderson, 892 A.2d 1061, 1064 (Del.2006) ("We are not asked to, and therefore we do not, rule on the constitutionality of the 'automatic companion rule.' "); Hunter v.
