On Appeal from the County Criminal Court No. 3

OPINION

Before Justices Lang, Myers, and Brown 

Opinion by Justice Myers

Appellee Amy Lyons was charged with driving while intoxicated (DWI) and 

subsequently filed a motion to suppress, arguing that evidence was obtained through “an illegal 

stop/detention.” The trial court granted the motion. The State appeals the trial court’s order, 

contending the trial court erred by granting the motion to suppress. We reverse and remand.

BACKGROUND AND PROCEDURAL HISTORY

Irving Police Officer Khanh Quach testified that on May 26, 2013, at approximately 2:40 

a.m., he received a dispatch to a location on Highway 161, the President George Bush turnpike, 

to assist the DPS on “[a] possible DWI.” According to the “call notes,” the dispatch concerned

“a vehicle with two deflated tires.” Officer Quach proceeded to that location. 

Based on the video footage from the police car’s dashboard camera, which was 

introduced at the suppression hearing, and the officer’s testimony at the hearing, upon arriving at 
–2–

the scene, Officer Quach pulled his patrol car behind a North Texas Tollway Authority (NTTA) 

truck that was parked on the shoulder of the road behind a white Chevy SUV. Officer Quach did 

not have his overhead emergency lights activated and was, at that point, the only officer on the 

scene. In the video, Officer Quach exits his patrol car and walks up to NTTA truck driver. He 

asks, “Is this the DWI, or is there another one?” The NTTA driver––he was never identified by 

name and did not testify at the suppression hearing––can be heard saying “she got two flats,” but 

the rest of his response is inaudible. Officer Quach testified that the NTTA driver told him 

appellee “had shown signs of intoxication, and he told me that she had two blown-out tires.” 

Officer Quach also recalled, “If I remember right from the video, he said that she smelled––she 

had carried the odor of alcohol.” 

The next voice that is distinctly heard in the video is the officer asking, “You got DPS 

coming out here?” Officer Quach also asks: “Can you confirm? If not, I’ll take it.” In the 

background, the NTTA driver says, “She doesn’t know what happened to her car.” The officer

asks the NTTA driver if the SUV hit something. The NTTA driver then says, “[S]he must hit 

something [sic],” but the rest of his response is inaudible. The officer asks, “Two flats?” The 

NTTA driver’s response is, again, inaudible. Officer Quach tells the dispatcher that “[t]here’s no 

DPS officers out here.” 

Officer Quach walks past the NTTA truck and approaches the SUV. His weapon is not 

drawn, but he can be seen in the video holding a flashlight in his hand. At the suppression 

hearing, he testified that when he walked up to the vehicle, appellee was sitting in the driver’s 

seat, the keys were in the ignition, and the engine was running. In the video, Officer Quach can 

be heard asking appellee, “You okay, Ma’am?” She responds, “Yeah, I’m . . . , at which point 

the officer interjects, “What happened?” Appellee says, “My tire blew out.” The officer asks, 

“Your tire blew out? Which one?” Appellee’s response to this question is inaudible. The 
–3–

officer then asks, “On which side?” Appellee says, “It’s one of those.” The officer replies, 

“Okay, give me a second.” Officer Quach testified at the hearing that as he “contacted” appellee, 

he “also smelled the odor of alcohol” and “noticed that she was slurring” her speech, and then he 

“asked her to step out of the vehicle at that point.”

In the video, after speaking to appellee, Officer Quach can be heard telling the NTTA 

driver, “We’ll take it.” When another officer arrives, Officer Quach speaks to him briefly and 

says, “Hey, I’m going to take this DWI, unless you want it.” After the other officer drives away, 

Officer Quach drives his patrol car around the NTTA truck and parks on the shoulder of the road 

behind appellee’s vehicle.

1

 He walks back to the driver’s side of the SUV, opens the door, and

asks appellee, “Okay, do you know what you hit or anything?” Appellee says, “I don’t know. 

It’s just like my tire blew out.” Officer Quach replies, “Okay, you’re not hurt or anything?” 

Appellee says “no.” The officer says, “Okay,” after which he asks appellee where she was 

coming from. She replies, “Just from, uh, up north.” The officer asks: “Up north? Okay, like 

Oklahoma north?” Appellee says “no.” The officer asks, “Where at?” Appellee says, “We were 

coming from Buffalo Wild Wings.” The officer asks appellee if she would mind stepping out of 

her vehicle to talk to him, and that he did not want to stand next to her vehicle given the traffic 

on the highway. Officer Quach administered field sobriety tests, after which he placed appellee

under arrest for DWI. 

Officer Quach testified at the suppression hearing that he did not see appellee driving or 

see the tire blowout, nor did the NTTA driver. The NTTA driver saw appellee’s vehicle on the 

side of the road. Officer Quach testified that the reason for approaching appellee’s car was the 

NTTA driver’s report of a possible intoxicated driver. The trial court was skeptical of the State’s

the scene, his patrol car’s emergency lights were also flashing.

case, stating it needed more than a conclusory statement “that [appellee is] intoxicated” to find 

the detention was lawful. But the court withheld ruling and passed the case to give the parties 

one week to research and locate supporting authority for their positions.

When the hearing reconvened one week later, the trial court heard arguments and legal

authorities from both sides. The State argued the encounter between appellee and Officer Quach

was consensual, not a detention.2 The State conceded the community caretaking exception to the 

warrant requirement was inapplicable. See, e.g., Diaz v. State, No. 05–12–00624–CR, 2013 WL 

1614745, at *1 (Tex. App.––Dallas April 11, 2013, no pet.) (not designated for publication) 

(stating that “community caretaking” exception to the warrant requirement provided that “a 

police officer may stop and assist an individual whom a reasonable person, given the totality of 

the circumstances, would believe is in need of help”). Counsel for appellee argued appellee had 

been subjected to a detention that was not supported by specific, articulable facts. 

The trial court found it was Officer Quach’s intent to conduct a DWI investigation prior 

to his initial contact with appellee. The trial court also found that, from the officer’s perspective,

appellee was not free to leave. The court stated on the record: 

So, I think from the officer’s state of mind, while he was never 

specifically asked, . . . is he [sic] free to leave or not, it would appear to me that 

from the officer’s testimony that “I am approaching this person to investigate a 

driving while intoxicated case and not to see if she was okay,” that it would 

appear from the officer’s state of mind that she wasn’t free to leave. 

 2 The State cited State v. Priddy, 321 S.W.3d 82 (Tex. App.––Fort Worth 2010, pet. ref’d), where the court of appeals reversed a trial 

court’s grant of a motion to suppress and concluded the police officer’s initial encounter with Priddy was a consensual police-citizen encounter 

that transitioned into an investigative detention supported by reasonable suspicion. Id. at 87-88. In that case, the police received a dispatch from 

an unidentified person at a hospital who said that the defendant had just left the hospital and appeared to be intoxicated. Id. at 84. The person

also provided the defendant’s name, address, the make of her vehicle, and the location and direction of her departure. Id. The officer located the 

defendant’s vehicle about fifteen minutes later in a business area; the vehicle was legally parked but still running with its lights on. Id. The 

officer parked behind the defendant’s vehicle, turned his spotlight on, and ran the vehicle’s license tags. Id. When the officer approached the 

defendant’s vehicle, he saw the defendant inside “laid over the seat,” eating a hamburger. Id. When the defendant saw the officer she sat up and 

rolled down the window, after which the officer smelled the odor of an alcoholic beverage and observed that the defendant had glazed and 

bloodshot eyes. Id. The court of appeals concluded that the officer’s initial interaction was not illegal because he had not engaged in a show of 

authority that would lead a reasonable person to believe she was not free to terminate the encounter. Id. at 87–88. The court also concluded that 

once the defendant rolled down her window and the officer noticed her glazed and bloodshot eyes and smelled the odor of an alcoholic beverage, 

“the voluntary encounter became an investigative detention based upon reasonable suspicion that [the defendant] had been driving while 

intoxicated.” Id. at 88.
–5–

And I also find factual difference––I find some significance that an NTTA 

officer was already there.3

 So if we were just concerned about taking care of her 

disabled car and her situation, there was already someone there to do that, that it 

would be pretty clear, I think, to everyone, including the Defendant, that the 

police were here for some other reason than to see if she was okay, because there 

was already someone there to take care of those matters.

So bringing in a second person of much higher authority, a policeman 

would have, I think––again, unless, circumstantially, to get where I am, that I 

have to––whichever way I go, but it would appear to me that she would feel with 

the NTTA officer, obviously, getting someone else involved, being a reasonable 

deduction from the evidence––well, it’s direct evidence that he did, and it would 

be a reasonable deduction from the evidence that she would feel that way, that 

this officer was here not for caretaking but for criminal investigation.

The trial court further found, based on the totality of the circumstances, that this was not a

voluntary encounter but rather “a detention to investigate for possible driving while intoxicated, 

as the officer testified that was his reason for doing the stop.” The court noted that the officer 

was dispatched to the scene of a possible intoxicated driver, he drove up to the location, talked to 

the NTTA driver, who indicated (as recalled by the trial court) that “this could be or is a DWI,” 

at which point the officer approached appellee’s SUV. The trial court concluded appellee “was 

not free to go at that time and that it was an illegal detention.”4

 The trial court specifically 

concluded as follows: (1) Officer Quach’s initial encounter with appellee was not consensual;

(2) Officer Quach’s initial encounter with appellee was not a legal community caretaking duty;

and (3) Officer Quach did not have reasonable suspicion to detain appellee for a DWI 

investigation during his initial encounter with her. The trial court granted the motion to 

suppress. 

DISCUSSION

In one issue, the State contends the trial court erred by granting appellee’s motion to 

 3 The trial court is referring to the factual difference between Priddy and the instant case. 

4 Just before the end of the first hearing, when defense counsel referred to the portion of the video where the officer asked appellee “Ma’am 

are you okay,” and she responded, the court states, “Yeah, that’s the detention.”

suppress because, under the totality of the circumstances, Officer Quach’s conduct did not 

constitute a detention. The State argues that this was a consensual encounter. The State does not 

rely on the community caretaking exception. 

Standards of Review

We review a trial court’s ruling on a motion to suppress for an abuse of discretion, and 

will overturn the trial court’s ruling only if it is outside the zone of reasonable disagreement. 

Johnson v. State, 414 S.W.3d 184, 192 (Tex. Crim. App. 2013); Martinez v. State, 348 S.W.3d 

919, 922 (Tex. Crim. App. 2011). We apply a bifurcated standard of review, giving almost 

complete deference to the trial court’s determination of historical facts and mixed questions of 

law and fact that rely upon an assessment of the credibility and demeanor of a witness, but 

applying a de novo standard of review to pure questions of law and mixed questions that do not 

depend on credibility determinations. Arguellez v. State, 409 S.W.3d 657, 662 (Tex. Crim. App.

2013); Martinez, 348 S.W.3d at 923. If, as in this case, the trial court makes express findings of 

fact, we review the evidence in the light most favorable to the trial court’s ruling and determine 

whether the evidence supports these factual findings. Valtierra v. State, 310 S.W.3d 442, 447 

(Tex. Crim. App. 2010). We must uphold the trial court’s ruling if it is reasonably supported by 

the record and correct under any applicable theory of law. Wade v. State, 422 S.W.3d 661, 667 

(Tex. Crim. App. 2013); Hereford v. State, 339 S.W.3d 111, 117–18 (Tex. Crim. App. 2011). 

Determining whether a given set of facts amount to a consensual police-citizen encounter 

or a detention under the Fourth Amendment is an issue of law. Johnson, 414 S.W.3d at 192. 

The application of legal principles to a specific set of facts is an issue of law and is subject to de 

novo review. Id. Thus, whether Officer Quach’s initial interaction with appellee constituted a 

consensual police-citizen encounter or an illegal detention is subject to de novo review. See id. 

We review the facts surrounding the police-citizen interaction by considering the “totality 
–7–

of the circumstances,” not focusing on any one particular detail in isolation. State v. GarciaCantu, 253 S.W.3d 236, 244 (Tex. Crim. App. 2008); Wiede v. State, 214 S.W.3d 17, 25 (Tex. 

Crim. App 2007). As with determinations of probable cause, a piecemeal or “divide and 

conquer” approach is prohibited. Garcia-Cantu, 253 S.W.3d at 244. 

Applicable Law

The Fourth Amendment to the United States Constitution protects against unreasonable 

searches and seizures. U.S. CONST. amend. IV. The temporary detention of a citizen by a police 

officer for investigation constitutes a seizure under the Fourth Amendment. Terry v. Ohio, 392 

U.S. 1, 16 (1968); Priddy, 321 S.W.3d at 86. However, not every interaction between a police 

officer and citizen implicates the Fourth Amendment. Priddy, 321 S.W.3d at 86. As the Texas 

Court of Criminal Appeals has explained:

There are three distinct types of police-citizen interactions: (1) consensual 

encounters that do not implicate the Fourth Amendment; (2) investigative 

detentions that are Fourth Amendment seizures of limited scope and duration that 

must be supported by a reasonable suspicion of criminal activity; and (3) arrests, 

the most intrusive of Fourth Amendment seizures, that are reasonable only if 

supported by probable cause. 

Wade, 422 S.W.3d at 667; Chambers v. State, 397 S.W.3d 777, 781 (Tex. App.—Houston [14th] 

2013, pet. ref’d); Priddy, 321 S.W.3d at 86. For Fourth Amendment purposes, a detention 

occurs “[w]hen a police officer detains someone by restricting his or her movements through 

either a show of force, the use of physical restraint, or by communicated commands,” such that 

the citizen is no longer free to move independent of police direction. Grissom v. State, 262 

S.W.3d 549, 552 (Tex. App.—Texarkana 2008, no pet.). Detentions trigger Fourth Amendment 

search and seizure restrictions and require reasonable suspicion to support an officer’s conduct. 

Garcia-Cantu, 253 S.W.3d at 238. “Unlike an investigative detention or an arrest—each a 

seizure for Fourth Amendment purposes—an encounter is a consensual interaction, which the 

citizen may terminate at any time.” Priddy, 321 S.W.3d at 86. 
–8–

“Law enforcement officers are permitted to approach individuals without probable cause 

or reasonable suspicion to ask questions or even to request a search.” Priddy, 321 S.W.3d at 87; 

see also Florida v. Bostick, 501 U.S. 429, 434–35 (1991); Florida v. Royer, 460 U.S. 491, 497–

98 (1983). “Such an encounter does not require any justification on the officer’s part.” Priddy, 

321 S.W.3d at 87. Thus, when the officer approaches someone to engage them in conversation, 

even if such contact is part of a formal criminal inquiry or investigation, such contact, without 

more, does not implicate Fourth Amendment protection. Grissom, 262 S.W.3d at 552. It is, 

instead, merely an encounter between the citizen and the police. Id. “Such interactions may 

involve inconvenience or embarrassment, but they do not involve official coercion.” Priddy, 321 

S.W.3d at 87; see also Garcia-Cantu, 253 S.W.3d at 243. “So long as a reasonable person 

would feel free to disregard the officer’s questions and go about his or her business, the 

encounter is consensual and merits no further constitutional analysis.” Priddy, 321 S.W.3d at 87; 

see also Bostick, 501 U.S. at 434. A Fourth Amendment seizure occurs when the implication 

arises that the officer’s display of authority cannot be ignored, avoided, or ended. Priddy, 321 

S.W.3d at 87; Garcia–Cantu, 253 S.W.3d at 243. 

“Distinguishing an ‘encounter’ from a ‘detention’ is not always easy,” especially 

considering the diversity in police-citizen interactions. Grissom, 262 S.W.3d at 552. Courts 

consider the time, place, and surrounding circumstances of a police-citizen interaction when 

determining whether the interaction was consensual. State v. Woodard, 341 S.W.3d 404, 411

(Tex. Crim. App. 2011). 

Circumstances indicating that a police-citizen interaction is a seizure, rather than a 

consensual encounter, include the threatening presence of several officers, the 

officer’s display of a weapon, physical touching of the citizen by the officer, the 

officer’s words or tone of voice indicating that compliance with the officer’s 

requests might be compelled, flashing lights, or the blocking of a suspect’s 

vehicle. 

Priddy, 321 S.W.3d at 87 (citing United States v. Mendenhall, 446 U.S. 544, 554 (1980)). 
–9–

“[A]bsent this type of evidence, otherwise inoffensive conduct between a citizen and a police 

officer cannot, as a matter of law, amount to a seizure of that person.” Id.; Mendenhall, 446 U.S. 

at 555. 

“There is no bright-line rule to determine when an encounter becomes a seizure.” State v.

Castleberry, 332 S.W.3d 460, 466–67 (Tex. Crim. App. 2011). “Instead, courts must take into 

account the totality of the circumstances surrounding the interaction to determine whether a 

reasonable person would have felt free to ignore the police officer’s request or terminate the 

encounter.” Id. at 467; Wade, 422 S.W.3d at 667. “If ignoring the request or terminating the 

encounter is an option, then no Fourth Amendment seizure has occurred.” Wade, 422 S.W.3d at 

668. A court must step into the shoes of the defendant and make this determination from a 

common, objective perspective. Castleberry, 332 S.W.3d at 467. “The time, place, and 

surrounding circumstances must be taken into account, but the officer’s conduct is the most 

important factor in determining whether a police-citizen interaction is a consensual encounter or 

a Fourth Amendment seizure.” Id. (citing Garcia-Cantu, 253 S.W.3d at 244); see also Woodard, 

341 S.W.3d at 411. 

Analysis

In its findings of fact, the trial court found that “when Officer Quach arrived in his patrol 

car, he did not have his overhead lights activated,” that he approached appellee’s vehicle 

“without a weapon drawn” and “never exhibited a weapon,” that Officer Quach’s patrol car was 

parked “without any emergency lights or overhead lights activated,” that upon his initial contact 

with appellee Officer Quach “never told [appellee] to exit her vehicle,” that he “never told 

[appellee] to roll down her window,” that “Officer Quach was the only law enforcement officer 

on scene” during his initial contact with appellee, and that he “never physically touched 

[appellee].” The trial court also expressly found, at the conclusion of the suppression hearing, 
–10–

that Officer Quach “did not force [appellee] out of the car before speaking to her,” “that it would 

not be necessary to block the [appellee’s] car because the car was immovable at the time,” and 

“that there was no overt showing of authority [by Officer Quach] other than [his wearing of] a 

police uniform and badge.” 

The State relies on these findings to argue that, based on the totality of the circumstances, 

there was no detention of appellee by Officer Quach “up to the point in time that Officer Quach

asked Appellee if she was ‘OK.’” The State also argues that upon perceiving the smell of an 

alcoholic beverage coming from appellee, Officer Quach possessed facts providing him with 

reasonable suspicion to conduct an investigatory detention to determine whether appellee was 

intoxicated. Appellee responds, in part, by noting that her car was on the shoulder of the road

and immobilized because it had two “blown-out” tires, and “that in full darkness at 2:40 a.m., on 

a major freeway with traffic speeding by, a reasonable person would not simply have walked 

away and abandoned her vehicle, particularly not with a tow truck5 and a NTTA employee on the 

scene to render assistance.” 

The proper inquiry in a case such as this is not whether a reasonable person would have 

believed she was free to leave, as appellee suggests, but, as pronounced by the Supreme Court in 

Bostick, whether a reasonable person would feel free to decline the officer’s requests or 

otherwise terminate the encounter. See Bostick, 501 U.S. at 436; see also State v. Valasquez, 994 

S.W.2d 676, 679 (Tex. Crim. App. 1999).

 As we noted earlier, law enforcement officers are 

free to approach individuals and ask them questions or even request a search, and such 

encounters do not require any justification on the officers’ part. Priddy, 321 S.W.3d at 87. A 

 5 It is unclear from the video whether the NTTA vehicle was actually a tow truck, but the record from the suppression hearing shows that 

the prosecutor repeatedly referred to it as a tow truck. 

6 The “reasonable person” test “presupposes an innocent person.” Bostick, 501 U.S. at 438 (emphasis omitted) (citing Royer, 460 U.S. at

519 n.4 (Blackmun, J., dissenting)). This standard ensures the scope of Fourth Amendment protection does not vary with the state of mind of the 

individual being approached. Id. (quoting Michigan v. Chesternut, 486 U.S. 567, 574 (1988)).
–11–

seizure does not occur “simply because a police officer approaches an individual and asks a few 

questions.” Bostick, 501 U.S. at 434. The court of criminal appeals has also held that a seizure 

does not occur merely because an officer approaches a parked car in a public place and knocks 

on the window. See Merideth v. State, 603 S.W.2d 872, 873 (Tex. Crim. App. 1980); Stewart v. 

State, 603 S.W.2d 861, 861–62 (Tex. Crim. App. 1980); see also State v. Bryant, 161 S.W.3d 

758, 760–62 (Tex. App.––Fort Worth 2005, no pet.); Ashton v. State, 931 S.W.2d 5, 6 (Tex.

App.––Houston [1st Dist.] 1996, pet. ref’d). Likewise, the fact that the individual’s vehicle was 

already parked or stopped when the officer arrived does not answer the question of whether the 

interaction between the officer and the individual constituted an encounter or a detention. See 

Garcia-Cantu, 253 S.W.3d at 245 n.43; Garza v. State, 771 S.W.2d 549, 556 (Tex. Crim. App. 

1989); Martin v. State, 104 S.W.3d 298, 301 (Tex. App.––El Paso 2003, no pet.).

The restriction on appellee’s movement was the condition of her vehicle––the “blownout” tires. Appellee could not drive away, and she may have been hesitant to leave her disabled 

car parked along the shoulder of a busy highway at 2:40 a.m., when an NTTA truck was already 

on the scene. Appellee’s freedom of movement, however, was restricted by a factor independent 

of police conduct––i.e., appellee’s vehicle was disabled. The focus of our inquiry is not on 

whether a defendant’s movements were confined due to circumstances independent of police 

action, but on the police conduct. See Bostick, 501 U.S. at 436 (“Bostick was a passenger on a 

bus that was scheduled to depart. He would not have felt free to leave the bus even if the police 

had not been present. Bostick’s movements were ‘confined’ in a sense, but this was the natural 

result of his decision to take the bus; it says nothing about whether or not the police conduct at 

issue was coercive.”); Immigration and Naturalization Serv. v. Delgado, 466 U.S. 210, 218

(1984) (workers may not have felt free to leave when INS agents stood near the building’s exits, 

while other agents walked through factory questioning workers, but this was not the result of 
–12–

police activity because, “[o]rdinarily, when people are at work their freedom to move about has 

been meaningfully restricted, not by the actions of law enforcement officials, but by the workers’

voluntary obligations to their employers.”). Although the surrounding circumstances, including

time and place, are taken into account, the officer’s conduct is the most important factor when 

deciding whether an interaction was consensual or a Fourth Amendment seizure. See Woodard, 

341 S.W.3d at 411; Castleberry, 332 S.W.3d at 467. 

As the State points out, the factors that might indicate the police interaction with appellee 

was a seizure, rather than a consensual encounter, are simply not present here. The emergency 

or overhead lights on Officer Quach’s vehicle were not activated, he approached appellee’s 

vehicle without his weapon drawn, he never exhibited his weapon, he did not force appellee out 

of her car, he did not ask her to exit the vehicle before speaking to her, he never physically 

touched appellee before she exited the vehicle, he never told appellee to roll down her window, 

Officer Quach did not block appellee’s vehicle, there was no overt showing of authority apart 

from the officer’s police uniform, holstered weapon, and badge, and Officer Quach was the only 

officer on the scene during the initial encounter with appellee. Furthermore, the video recording 

of the incident shows that the officer never spoke to appellee in a commanding or authoritative 

tone of voice, and that he addressed appellee in a normal, conversational tone. See Priddy, 321 

S.W.3d at 87. 

Appellee also argues that the State conceded Officer Quach was not exercising a 

community caretaking function, and that the evidence shows he believed he was investigating a 

possible DWI. However, the detention test is objective, so an officer’s subjective beliefs and 

uncommunicated state of mind do not control. See Wade, 422 S.W.3d at 668; Weide v. State, 

214 S.W.3d 17, 25 (Tex. Crim. App. 2007) (“The subjective intent or motivations of law 

enforcement officials is not taken into account when considering the totality of the 
–13–

circumstances.”); Martin, 104 S.W.3d at 301 (“An officer’s unarticulated intent to detain a 

person is irrelevant in determining whether the person was detained.”). 

Taking into account all of the circumstances surrounding the interaction, we conclude the

officer’s conduct in this case would not have communicated to a reasonable person that she “was 

not at liberty to ignore the police presence and go about [her] business.” See Bostick, 501 U.S. at 

437. Based on the totality of the circumstances, we therefore agree with the State that the initial 

interaction between Officer Quach and appellee, up to the point when the officer first approached 

the driver’s side window of appellee’s vehicle and asked her if she was “okay,” was a voluntary 

encounter. The trial court erred by concluding Officer Quach’s initial interaction with appellee 

was not consensual. When Officer Quach contacted appellee and smelled the odor of alcohol 

and noticed she was slurring her speech, the voluntary encounter became an investigative 

detention based upon reasonable suspicion appellee had been driving while intoxicated. See, 

e.g., Priddy, 321 S.W.3d at 88 (officer had reasonable suspicion defendant had been driving 

while intoxicated, which justified detention, after defendant rolled down the window of her 

vehicle, which was parked with the engine running, and officer smelled odor of an alcoholic 

beverage and saw defendant’s bloodshot and glazed eyes); Rubeck v. State, 61 S.W.3d 741, 745
