OPINION
delivered the opinion of the Court
Appellant was charged with possession with intent to deliver cocaine. He filed a pre-trial motion to suppress the crack cocaine that officers found during a warrant-less search of a van that appellant had borrowed. After hearing the evidence, the trial judge ruled that appellant’s original detention was reasonable and that he lacked standing to challenge the search of the van. A jury then found appellant guilty and sentenced him to twenty-two years in prison. The court of appeals affirmed, agreeing that appellant lacked standing to challenge the van’s search and upholding appellant’s detention, even though it was based largely on information from an anonymous tip. 1
We granted review to determine (1) whether a person who legitimately borrows a vehicle has standing to challenge its search, and (2) if appellant’s initial and continued detention was supported by reasonable suspicion. 2 We conclude that, although appellant originally had standing to challenge the search of the borrowed van, he abandoned any expectation of privacy *600 (and hence his standing) when he fled from the officers and the van. Second, the officers had reasonable suspicion to detain appellant that was not based solely on the anonymous tip, and appellant’s act of fleeing increased their suspicion and further justified his continued detention to await the arrival of a drug dog.
I. Background
On July 23, 2009, at 11:11 p.m., Officer Zimpelman was dispatched to a food store on Hattie Street in Fort Worth to respond to an “anonymous” 911 call. Although the tipster did not leave her name, Officer Zimpelman’s “call screen” displayed the tipster’s phone number and address. According to the caller, a black male named Neil Matthews, wearing a white muscle shirt and dark pants, was selling “crack” out of a white van parked in front of the store. This was a high-crime area, known for drug and weapons arrests.
When Officer Zimpelman pulled up to the food store, he saw a white van in front of it. He stopped behind the van, got out of his patrol car, and walked up to the passenger side window of the van, while his partner, Officer Smith, approached the driver’s side. Appellant was in the driver’s seat of the van, wearing a white muscle shirt and dark pants. He was just sitting there with the keys in the ignition and the engine off.
When Officer Zimpelman looked in the passenger window, he could see appellant’s right hand, but appellant’s left hand was hidden from view. Concerned that appellant was hiding a weapon “because that area is known for pretty much a high crime rate area,” Officer Zimpelman told appellant to show his other hand, but appellant ignored him. 3 When Officer Zim-pelman repeated his request, appellant said that he was showing his hands, even though his left hand remained hidden by the driver’s side door. Because it was close to midnight, difficult to see, and a high crime area, Officer Smith told appellant to get out of the van after he had repeatedly refused to show both his hands. Officer Smith led appellant to the back of the van and frisked him. Appellant was unarmed. When Officer Zimpelman asked appellant for his name, he said, “Cornelious Matthews.”
Based on the details from the anonymous tip, the fact that appellant’s name was very similar to “Neil Matthews” (the name provided by the tipster), and appellant’s gestures, Officer Zimpelman asked for consent to search the van. Appellant refused, stating that the van was not his, so he could not allow the search. 4 Officer Zimpelman explained to appellant that “he was sitting in the driver’s seat, so therefore he’s in the care, custody, and control of the vehicle, that he can provide ... permission.” Appellant responded “I don’t even have the keys.” Officer Zimpelman reminded him that the keys were in the ignition, but appellant still did not consent to the search.
Officer Zimpelman called dispatch and requested a K-9 unit. When appellant heard that request, “[h]is body became more tense. His eyes got larger” and his breathing became “more rapid, kind of the fight or flight response.” Officer Zimpel-man told a third officer to put appellant in *601 the back of the squad car for further investigation. But as the officers walked to the squad car, appellant took off running. Officer Zimpelman pursued appellant on foot for several blocks, finally caught him, and brought him back to the squad car. When they returned, the anonymous tipster was at the scene and identified herself as the caller. When officers discovered that she had outstanding warrants, they arrested her as well.
K-9 Officer Macy arrived with his dog, Hutch, and conducted an “open-air sniff’ around the van. Hutch alerted, so the officers searched the van and found a package of marijuana in the driver’s-side door pocket and crack cocaine in a small compartment behind the driver’s seat. 5 The officers arrested appellant on drug charges.
Appellant filed a motion to suppress, but after hearing the testimony of Officer Zim-pelman, Officer Macy, and appellant, the trial judge denied the motion. The judge stated that appellant did not own or have any possessory interest in the van, and thus he did not have standing to challenge the search. 6 A year later, right before the trial began, appellant filed another motion to suppress that challenged his original detention while also rearguing the standing issue. After hearing testimony from the same witnesses, the trial judge ruled that appellant had standing to challenge the detention and search of his person, but that the detention and search were reasonable under the circumstances. 7 He again *602 concluded that appellant lacked standing to challenge the search of the van.
The court of appeals agreed that appellant did not have standing to challenge the search of the van. 8 Because appellant did not have complete dominion and control over the van and because the “owner’s grant of permission to Appellant to be in the vehicle does not rise to a claim of privacy consistent with historical notions of privacy[,]” he did not have a reasonable expectation of privacy in the van. 9
The court of appeals also held that appellant’s detention was supported by reasonable suspicion. 10 When the officers arrived at the food store, they were able to corroborate some of the tipster’s story—a man wearing the described clothing was sitting in the described vehicle. 11 In addition, the officers knew that the location was a “high-crime, high-drug area.” 12 After they approached the windows of the van, appellant refused to comply with instructions to show both of his hands. 13 Although a Terry frisk did not uncover any drugs or weapons, “the other facts known to the officers by personal observation increased the indicia of reliability of the anonymous tip.” 14 The court of appeals held that the entire investigative detention was lawful. 15 We granted review of both of those holdings.
II. Reasonable Suspicion for the Investigative Detention
In his second ground for review, appellant argues that his continued detention after the Terry frisk was unlawful because it was not supported by reasonable suspicion; it was supported only by the 911 call of an anonymous tipster. Appellant now purports to concede that the officers’ original approach, request for him to get out of the van, and the pat-down search were permissible. He argues that “the Constitutional line was crossed” when officers wanted him to sit in the patrol car and wait for approximately fifteen to twenty-five minutes for a drug dog to arrive, rather than release him when they did not find anything illegal during the Terry frisk or initial investigation. 16 Appellant nevertheless continues, within his brief, to challenge the propriety of the initial detention. We therefore address the constitutionality of the detention from its inception.
A. Legal Principles
Under the Fourth Amendment, a brief investigatory detention must be justi *603 fied by reasonable suspicion. 17 “A police officer has reasonable suspicion to detain if he has specific, articulable facts that, combined with rational inferences from those facts, would lead him reasonably to conclude that the person detained is, has been, or soon will be engaged in criminal activity.” 18 In determining whether an officer has reasonable suspicion to detain, we look at the totality of the circumstances through an objective lens, disregarding the officer’s subjective intent. 19 Although some circumstances may seem innocent in isolation, they will support an investigatory detention if their combination leads to a reasonable conclusion that criminal activity is afoot. 20
An anonymous tip alone is seldom sufficient to establish reasonable suspicion. 21 Reasonable suspicion is de-pendant not only on the content of the information possessed by law enforcement, but also on its reliability. 22 To support reasonable suspicion, an anonymous tip requires some indicia that the caller is credible or that his information is reliable. 23
Reasonable suspicion is not a carte blanche for a prolonged detention and investigation. The investigatory detention must be “reasonably related in scope to the circumstances which justified the interference in the first place.” 24 An officer must act to confirm or dispel his suspicions quickly. 25 But the temporary detention may continue for a reasonable period of time until the officers have confirmed or dispelled their original suspicion of criminal activity. 26 One reasonable method of confirming or dispelling the reasonable suspicion that a vehicle contains drugs is to have a trained drug dog perform an “open air” search by walking around the car. If the dog alerts, the presence of drugs is confirmed, and police *604 may make a warrantless search. 27 If the drug dog does not alert, the officer’s suspicions will normally be dispelled, and the citizen may go on his way. 28
B. Appellant’s Detention Was Reasonable
Appellant was seized, and the investigatory detention began, when he was ordered to get out of the van and was frisked for weapons. However, contrary to appellant’s claims, his detention was not based solely on the word of an unreliable anonymous tipster. Rather, the totality of the circumstances established reasonable suspicion to support the scope and duration of the officers’ investigatory detention.
Officer Zimpelman responded to an “anonymous” tip alleging that appellant was selling crack from a white van outside the food store. In addition to the description and location of the van, the tip not only contained a detailed description of appellant, but also identified him by name. While the specificity of this tip contains indicia of reliability, 29 we need not decide whether this tip alone supported reasonable suspicion because Officer Zimpelman had additional facts before making his investigatory detention.
After Officer Zimpelman received the dispatch call at 11:11 p.m., he confirmed that the described van contained the described man at the described location, a high-crime area known for drug and weapons violations. When he approached the passenger-side window of the van, he saw appellant concealing his left hand near the driver’s side door. 30 Fearing that appellant was holding a weapon, Officer Zimpel-man asked appellant to show both of his *605 hands. Appellant did not comply; rather, he glanced at Officer Zimpelman but ignored his request. When Officer Zimpel-man repeated his request to see appellant’s left hand, appellant responded that “he was showing ... his hands.” Officer Smith, standing near the driver’s side door of the van, told appellant to exit the van. Appellant complied and followed Officer Smith to the back of the van, where Officer Smith made a Terry frisk.
This investigatory detention was not based solely on the anonymous 911 call. 31 In addition to the tip,
• Officers discovered appellant in a high-crime area, known for drug and weapons offenses, late at night;
• He was dressed as the 911 caller had described and was named as the 911 caller had said;
• He was sitting in the driver’s seat of the van that the 911 caller had described with the key in the ignition, but the engine off. He was just sitting there; 32
• Appellant refused to comply with the officers’ request to show both of his hands, and he did so in a suspicious manner.
When coupled with the specific anonymous tip that appellant was selling “crack” from that van, the totality of circumstances established reasonable suspicion to briefly detain and investigate the officers’ suspicions. 33 With their suspicions aroused, officers requested that appellant exit the vehicle, and they performed a pat-down search. The pat-down did not reveal any contraband or weapons. Appellant argues, “It was at this point where the Constitutional line was crossed,” because instead of being released, Officer Zimpelman radioed for a K-9 unit and asked Officer Rodriguez to take appellant to the patrol car. 34 As appellant notes, “The testimony presented at the hearing established that [the wait for the K-9 unit] was expected to take between fifteen to twenty-five minutes.” 35
The post-frisk detention was not unreasonable, nor was it unnecessarily prolonged. Although the officers did not find any weapons or contraband during that frisk, the fact that appellant was not carrying a knife or a firearm did not address their suspicion that he was selling drugs from the van or that more drugs were in the van. To quickly confirm or dispel that suspicion, Officer Zimpelman called for a K-9 unit to make a walk-around search of the van. Although the wait for the K-9 unit was only expected to *606 take 15 to 25 minutes, 36 appellant did not wait at all. He took off running. This two-block flight only increased the officers’ suspicion that appellant was engaged in illegal activity. 37 Furthermore, this attempted flight constituted its own offense, evading arrest or detention. 38
Officer Zimpelman caught appellant and returned him to the patrol car. By this time, the K-9 unit had arrived, and a dog alerted to the van. The officers searched the van and found marijuana and crack cocaine. At no point was appellant unlawfully detained.
III. Standing to Challenge the Search of the Van
In appellant’s first ground for review, he argues that the court of appeals erred in holding that he lacked standing to challenge the search of the van. The rights protected by the Fourth Amendment to the U.S. Constitution and Article I, Section 9, of the Texas Constitution are personal. 39 As such, an accused must show that the search violated his, rather than a third party’s, legitimate expectation of privacy. 40 He must show (1) that he exhibited an actual subjective expectation of privacy in the place invaded (“i.e., a genuine intention to preserve something as private”) 41 and (2) that “society is prepared to recognize that expectation of privacy as objectively reasonable.” 42
To determine whether a person’s expectation of privacy is reasonable, we examine the totality of circumstances *607 surrounding the search, 43 guided by a non-exhaustive list of factors:
• whether the accused had a property or possessory interest in the place invaded;
• whether he was legitimately in the place invaded;
• whether he had complete dominion or control and the right to exclude others;
• whether, before the intrusion, he took normal precautions customarily taken by those seeking privacy;
• whether he put the place to some private use; and
• whether his claim of privacy is consistent with historical notions of privacy. 44
Although we defer to the trial judge’s factual findings, we review the legal issue of standing de novo. 45
A. Generally, a person driving a borrowed car has a subjective and reasonable expectation of privacy in that vehicle.
Normally, all six of the above factors indicate that a person who borrows a car with the owner’s permission has a reasonable expectation of privacy in that car. Although a borrower may not have the full panoply of ownership, he has some property or possessory rights. 46 And if his use of the car is authorized, it follows that his presence in the car is authorized. Because he holds the keys to the car, he may control who enters it and who drives it, thus his dominion or control is superior to all others. 47 Unless he flings open the doors or hands the keys to a mere passerby, the borrower likely uses the normal precautions customarily taken by those seeking privacy in their cars. And unless the borrower abandons the vehicle or converts it into a public bus, he likely puts the vehicle to private use. Finally, privacy in a borrowed car is consistent with the historical notions of a bailee’s privacy. 48
This recognition of a reasonable expectation of privacy in a borrowed car is hardly novel. Back in 1978, Professor LaFave wrote: “If the owner of a vehicle has turned it over to another person for some period of time, then surely this latter person has standing vis-a-vis the car during the duration of bailment.” 49 Relying on this language, we held that a defendant had' standing to challenge the search of a parked car that he had borrowed. 50 Several federal circuits recognized this privacy interest decades ago. 51 And many Texas *608 courts of appeals have also properly found a reasonable expectation of privacy in these circumstances. 52 Officer Zimpelman said it best at the motion-to-suppress hearing: “Just like if you rent a car from Enterprise, if you rent it, you’re not the owner, you’re leasing it. But you can let people in your car or not let people in your car.”
B. A borrower who abandons a car no longer has an expectation of privacy in it.
No person can reasonably expect privacy in property he abandons. Thus, “when a defendant voluntarily abandons property, he lacks standing to contest the reasonableness of the search of the abandoned property.” 53 But merely discarding property is not synonymous with *609 abandonment. In order to abandon property, the decision to abandon must be voluntary, and a defendant must intend to abandon the property. 54
Abandonment is not voluntary if it is the product of police misconduct. 55 It cannot be “ ‘coerced by unlawful police action such as approaching a suspect with the intention to arrest without probable cause [or by] the initiation of an illegal investigatory stop or search.’ ” 56
Intent to abandon “may be inferred from words, acts, and other objective facts-the question being whether the actor has voluntarily discarded or relinquished his interest in the property in question.” 57 The issue is not whether he intended to discard the property permanently, but rather whether he abandoned the property in such a way “that he could no longer retain a reasonable expectation of privacy with regard to it at the time of the search.” 58
Determining when a car is abandoned presents a unique challenge because cars differ from other types of personal property. They are somewhat like mobile locked suitcases.
[A] car and an overcoat are different; one can hardly expect privacy in an overcoat left on the street, but cars are regularly parked on the street for brief periods of time without an expectation that they will thereby be subject to entry. 59
But despite this inherent difference, when the circumstances indicate that a person intended to abandon a car, he also abandons any reasonable expectation of privacy in it. Thus, “[c]ourts have ... found cars to be abandoned when it appeared that the operator of a vehicle left the car behind in an effort to avoid apprehension by the police.” 60
*610 C. Appellant Lost His Standing to Challenge the Search of the Borrowed Van When He Took Flight and Abandoned It.
Before appellant fled, he had both a subjective and reasonable expectation of privacy in the white van. Appellant exercised a subjective expectation of privacy when he refused to consent to the search of the vehicle. The fact that his refusal was based on his argument that the van did not belong to him is not dispositive. Appellant did not claim that he had not been using the car, or that he had no connection to the car; he stated that the car did not belong to him, which was true, but that does not alone extinguish a right to privacy. Furthermore, appellant’s expectation of privacy was reasonable. The evidence at the motion to suppress showed that appellant had permission to use the vehicle, which belonged to Joaquin Cardo-na. Appellant was in the driver’s seat, the doors were closed, and the keys were in the ignition. There was no evidence that the van’s owner had revoked his consent or limited its scope.
However, appellant abandoned his reasonable expectation of privacy in the van when he fled. As explained above, the investigative detention of appellant was lawful. Officer Zimpelman got on his radio and requested a K-9 unit to perform a walk-around. When Officer Rodriguez began walking appellant to the patrol car to await the K-9 unit, appellant “took off running,” leaving the keys in the ignition of the vehicle. Appellant ran for two blocks and entered a vacant field. He stopped only when Officer Zimpelman activated his taser and pointed it at appellant. These circumstances show that appellant intended to abandon any expectation of privacy in the van he left behind. 61
IV. Conclusion
In sum, appellant’s detention was supported by reasonable suspicion. The officers did not rely solely on the content of an anonymous tip; other circumstances including the location, the time of night, and appellant’s suspicious behavior, combined with the officers’ corroboration of innocent details of that tip, contributed to their suspicion. Thus the initial investigatory detention of appellant was lawful, and the officers were diligent in calling for a K-9 dog to confirm or dispel that original suspicion.
We also agree with the court of appeals that appellant lacked standing to challenge the search of the van, but for somewhat different reasons that those relied upon by the trial or appellate courts. Although a person generally has an expectation of privacy in a borrowed vehicle, appellant abandoned this expectation of privacy by fleeing from the van.
*611 Therefore, we affirm the judgment of the court of appeals.
Notes
.
Matthews v. State,
No. 08-11-00157-CR,
. Appellant’s two grounds for review are:
1. Does a person have standing to contest an unlawful search where they are in possession of a vehicle with consent and permission of the vehicle’s owner?
2. Can the police detain a person to conduct a warrantless search based on an anonymous tip when the initial investigation provides zero evidence to show any law violation?
. Officer Zimpelman testified: "I told him to show me his hands. He glanced over at me, looked straight forward or straight ahead from where he was sitting toward the store, glanced back over at me.”
. At some point, Officer Zimpelman checked the vehicle registration and discovered that the van belonged to "Joaquin Cardona.” After appellant was in custody, a Hispanic man approached the officers and said that he owned the van.
.Appellant testified at the first suppression hearing, and his version of events differed significantly from Officer Zimpelman’s. ■ Appellant said that he was waiting in the van for his "Auntie” to meet him, when two officers approached the van and told him to show his hands. Then, according to appellant,
I showed him my hands. He asked for my ID, I gave him my ID. He told the other officer to keep an eye on me. And then he told me to step out [of] the car. So he ran to go check my name. And I didn’t have no warrants. And then the other officer searched me and they didn’t find nothing. And then I told him why was they messing with me. And my auntie came around the corner and she asked them why was they messing with me because she was about to take me home.
Appellant said that he refused to consent to the search of the van because it did not belong to him. But appellant claimed that he did not run away until a drug dog arrived and failed to alert. He said that the officers continued to harass him, so he ran away. Appellant stated that, after Officer Zimpelman caught him and brought him back to the van, a second drug dog circled the van and also failed to alert.
When reviewing the ruling on a motion to suppress, we view the evidence in the light most favorable to the trial judge’s ruling.
Wade v. State,
. The trial judge explained:
This is a situation where [appellant] from the very beginning denied ownership or an ownership interest in the vehicle involved. His reason for denying the officers the consent to search the vehicle was based upon the fact that it was not his vehicle, that he did not know what was in it, his assertion that he had no possession or ownership of the vehicle is apparent.
It’s also a situation where the vehicle is actually registered to another person who— and that person apparently appeared upon the scene and claimed ownership of the vehicle. So the Court is addressing the issue of standing [and] is going to determine from the facts this is a situation where [appellant] has no standing to complain about the search of the vehicle based on the circumstances in this case.
. In ruling that appellant's detention was reasonable, the trial judge found:
[T]he encounter with [appellant] was legitimate and reasonable under these circumstances. While initially the anonymous ... *602 caller ... probably did not realize that her phone number or address was being revealed as she made the call, potentially. Although she might not have realized that, that’s certainly not a surprise with modern technology.
And the fact that she later showed up indicates a willingness to be helpful and available for follow-up investigation. So I do think it’s important that she did show up and indicate her willingness to participate further in this matter. But the Court is going to find that the encounter was legitimate, that immediately the officers were able to confirm the details of the call. The Court is also going to find that under the circumstances, the Terry frisk of the defendant was reasonable under all the circumstances. The Court will also find that a brief period of detention following that is reasonable under the circumstances.

See United States v. Jodoin,
. Recently, in
Navarette v. California,
the Supreme Court held that an anonymous tip contained adequate indicia of reliability to support reasonable suspicion because the content of the tip indicated that it was based on eyewitness knowledge, was contemporaneously made, and was made to the 911 emergency system, which “has some features that allow for identifying and tracing callers, and thus provide some safeguards against making false reports with immunity.” 572 U.S. -,
Similarly, in this case the tipster called 911, and Officer Zimpelman's “call sheet” displayed the phone number and address associated with the call. However, the call sheet does not indicate who made the 911 call from that address or whether the caller knew that her number could be traced. Nor does access to such "call sheet” information necessarily increase the likelihood that a tip is reliable.
