MEMORANDUM OPINION

It was shortly past midnight as Officer Antony Brown of the Allen1 Police Department 

patrolled through an otherwise quiet residential neighborhood of the city and noticed a legally 

parked Volkswagen Jetta with its driver-side door open, its interior dome light on, and no visible 

person in or near it. Because an open door on an apparently unattended vehicle was “not a normal 

thing,” Brown turned his patrol car around to investigate the situation, reasoning that “[w]ith 

something like that, you don’t know if a car is broken into or, you know, or just what.” As he 

turned around and parked his patrol car in front of the Jetta, he saw a woman, later found to be 

Christi Beth Perrin, walking along that “same side of the road.” He ran the Jetta’s license plate 

and determined that the car was registered in another city. Brown saw Perrin get into the Jetta and 

begin to pull the car away from the parking space, when he turned on his overhead lights and 

stopped her car “to find out why she left her car sitting there with the door open and was walking 

. . . along the other vehicles on the roadway.”

When Brown spoke to Perrin, he noticed that her polo shirt was on backwards and that her 

eyes were abnormally dilated.

Perrin was charged with driving while intoxicated (DWI), a Class B misdemeanor offense. 

At trial, Perrin moved to suppress the evidence obtained following the traffic stop that eventually 

led to her arrest on the ground that the officer lacked reasonable suspicion to initiate the traffic 

 

1Originally appealed to the Fifth Court of Appeals in Dallas, Perrin’s case was transferred to this Court by the Texas 

Supreme Court pursuant to its docket equalization efforts. See TEX. GOV’T CODE ANN. § 73.001 (West 2013). 

Because this is a transfer case, we apply the precedent of the Dallas Court of Appeals to the extent it differs from our 

own. See TEX. R. APP. P. 41.3.

stop. The trial court denied her motion. In a jury trial, she was convicted and sentenced to six 

days in jail.

On appeal, Perrin contends that the trial court erred in denying her motion to suppress2

because the officer lacked reasonable suspicion to stop her vehicle.

We affirm the trial court’s judgment.

A routine traffic stop—a seizure—implicates both the United States and Texas 

Constitutions and, under both, must be reasonable. Berkemer v. McCarty, 468 U.S. 420, 436–37 

(1984); Francis v. State, 922 S.W.2d 176, 178 (Tex. Crim. App. 1996); see U.S. CONST. amend.

IV; TEX. CONST. art. I, § 9. It is undisputed that the officer here did not have a warrant to stop 

Perrin. Thus, the State was required to prove that the seizure was reasonable. See Delafuente v. 

State, 414 S.W.3d 173, 176 (Tex. Crim. App. 2013). Denying Perrin’s motion to suppress, the 

trial court implicitly found that the State met its burden, prompting this point of error on appeal.

We review a trial court’s ruling on a motion to suppress under a bifurcated standard of 

review, giving almost total deference to the trial court’s determination of historical facts that turn 

on credibility and demeanor while reviewing de novo other application-of-law-to-fact issues. See 

 

2Perrin told Brown that she was trying to visit a friend in Colleyville, a city more than thirty-five miles away. Perrin 

denied consuming alcohol, but admitted to Brown that, earlier that day, she had taken four prescription drugs, Valium, 

Depakote, Adderall, and Trazadone. Adderall is a nervous system stimulant, while the other three drugs are nervous 

system depressants. After administering the field sobriety tests, Brown arrested Perrin for DWI. Officer Matthew 

Johnson performed a drug recognition exam on Perrin and concluded that she lacked the normal use of her mental and 

physical faculties due to ingestion of central nervous system stimulants and depressants. She submitted to having her 

blood drawn and tested. According to the blood test, her blood contained therapeutic levels of amphetamine (such as 

Adderall) and diazepam, the generic name for Valium, but that the level of nordiazepam, a diazepam metabolite, 

exceeded therapeutic levels. The test also revealed an unquantified level of valproic acid, the generic name for 

Depakote. Forensic scientist Eduardo Padilla of the Department of Public Safety Austin Crime Laboratory, testified 

that each of the depressants could have an impairing effect on its own, and a greater impairing effect is possible when 

they are taken in combination.

Johnson v. State, 68 S.W.3d 644, 652–53 (Tex. Crim. App. 2002); Carmouche v. State, 10 S.W.3d 

323, 327 (Tex. Crim. App. 2000). Appellate courts should also afford nearly total deference to 

trial courts’ rulings on application-of-law-to-fact questions, also known as mixed questions of law 

and fact, if the resolution of those ultimate questions turns on an evaluation of credibility and 

demeanor. Guzman v. State, 955 S.W.2d 85, 89 (Tex. Crim. App. 1997). We are to conduct a 

de novo review of mixed questions of law and fact not falling within this category. Id. We must 

affirm the trial court’s decision if it is correct on any theory of law that finds support in the record. 

Osbourn v. State, 92 S.W.3d 531, 538 (Tex. Crim. App. 2002).

Law enforcement officers may stop and briefly detain individuals suspected of criminal 

activity on less information than is constitutionally required for probable cause to arrest. Terry v. 

Ohio, 392 U.S. 1, 22 (1968). To make an investigative stop, the officer must possess a reasonable 

suspicion based on specific, articulable facts that, in light of the officer’s experience and general 

knowledge, would lead the officer to reasonably conclude the person detained actually is, has been, 

or soon will be engaged in criminal activity. United States v. Sokolow, 490 U.S. 1, 9–10 (1989); 

Garcia v. State, 43 S.W.3d 527, 530 (Tex. Crim. App. 2001); Zervos v. State, 15 S.W.3d 146, 151 

(Tex. App.—Texarkana 2000, pet. ref’d); see TEX. CODE CRIM. PROC. ANN. art. 14.01(b); Wade v. 

State, 422 S.W.3d 661, 668 (Tex. Crim. App. 2013). “This is an objective standard that disregards 

any subjective intent of the officer making the stop . . . .” Ford v. State, 158 S.W.3d 488, 492 

(Tex. Crim. App. 2005). The facts used to support the investigative stop must support more than 

a mere hunch or suspicion. Davis v. State, 947 S.W.2d 240, 244 (Tex. Crim. App. 1997).

Here, the specific facts show (a) an unusual activity, an open door of an unattended car at 

12:30 a.m.; (b) evidence connecting Perrin to the unusual activity, her entry into the car and her 

act of starting to drive it away; and (c) an indication that the unusual activity is related to a crime, 

reasonable suspicion that burglary or another crime is, has, or will be committed when a car door 

is left open in an unattended car in the middle of the night.3 See Martinez v. State, 348 S.W.3d 

919, 923 (Tex. Crim. App. 2011). Therefore, the record supports the trial court’s ruling that Brown 

had reasonable suspicion to stop Perrin’s car. Accordingly, we overrule this point of error and 

affirm the trial court’s judgment.

3While there are several innocent, yet reasonable explanations for why Perrin’s car door was open, reasonable 

suspicion does not depend on the “most likely explanation” for a suspect’s conduct, and reasonable suspicion may 

exist even if the circumstances standing alone may be just as consistent with innocent activity as with criminal activity.
