OPINION
delivered the opinion of the Court
On the State’s petition for discretionary review, we determine that the court of appeals erred (1) by failing to apply a
de novo
standard of review to the trial court’s ultimate legal determination that Clint Saenz, appellee, was in custody when he made incriminating statements to police, and (2) by failing to abate the appeal for further findings of fact by the trial court. We reverse and remand this case to the court of appeals with instructions to abate
I. Background
A. Facts
Just after two in the morning, Officer Bintliff was dispatched to a Corpus Christi fast-food restaurant following a call of a disturbance between several customers and two intoxicated men. When he arrived at the location, Officer Bintliff encountered two men whose clothing matched the caller’s description. The men were sitting inside a truck with the engine running in the restaurant’s parking lot. The officer approached the truck. He told the passenger, who was leaning his head outside the truck and pointing into the restaurant while yelling, to stop yelling and get back inside the truck, and told the driver, appellee, to turn off the truck.
Officer Bintliff noticed that appellee showed signs of intoxication. The officer told appellee three times to turn off the truck before appellee complied. Appellee had answered the officer’s initial requests to turn off the truck with claims that he was not driving and that he was moving the truck for someone else. The officer had appellee exit the truck, at which time he also smelled alcohol on appellee’s breath and saw that his eyes were bloodshot. To investigate his suspicion that appellee may have been driving while intoxicated, he placed appellee unhandcuffed into the back of his patrol car and called for a department DWI specialist. 1
Officer Sanders responded to the call. He took over the investigation from Officer Bintliff and spoke to appellee, who remained in the patrol car unhandcuffed. In response to questions posed by Officer Sanders, appellee said that he “drove the vehicle there” to the restaurant and had become involved in a “fight.” Appellee also said that he “tried to break up the fight” and that he had visited “several ... local bars” earlier in the evening. In response to the officer’s question about how much alcohol he had consumed that night, appellee admitted to “drinking approximately six beers in four hours.” While speaking, appellee had a moderate odor of alcohol on his breath, slurred his speech, and had bloodshot eyes. In light of the signs of intoxication, Officer Sanders asked appellee for a breath sample. Appellee refused. Explaining his decision, appellee said that he had “a much higher tolerance” for alcohol because “he drinks very often.” Appellee failed field sobriety tests and was arrested for DWI.
B. Pretrial Motion to Suppress Statements and Trial Court’s Factual Findings
After he was charged with DWI, appel-lee filed a pretrial motion to suppress his statements to Officer Sanders. At the pretrial hearing on the motion, appellee argued that his statements to Officer Sanders were inadmissible because they were obtained while he was in custody without his having received the statutory
The trial court granted the motion and suppressed appellee’s oral statements. In response to the State’s request, the trial court made findings of fact and conclusions of law. Those findings and conclusions stated that Officer Bintliff had no reasonable suspicion to detain appellee for the disturbance in the restaurant and that ap-pellee was “under arrest for suspicion of DWI when Officer Sanders began questioning” him without giving him the statutory warnings. 2 The trial court’s findings of fact omitted many details, such as whether the trial court believed that the officers were credible witnesses, whether the trial court believed that Officer Bintliff told appellee that he was not free to leave when appellee was placed in the police car or whether the officer said nothing, and how long appellee had been in the police car when he made the statements to Officer Sanders.
C. The Court of Appeals
After concluding that a deferential standard of review was appropriate for this mixed question of law and fact, the court of appeals held that the trial court properly suppressed appellee’s oral statements because they were made while he was in custody without having received the statutory warnings.
State v. Saenz,
No. 13 — 11— 00328-CR,
We granted the State’s two grounds in its petition for discretionary review to address: (1) whether the court of appeals erred (a) by applying a deferential standard of review to the determination that appellee was in custody, and (b) by failing to remand for more complete findings of fact by the trial court; and (2) whether the court of appeals erred in its ultimate determination that appellee’s statements were obtained in violation of
Miranda v.
Arizona,
II. Standard of Review for Determination of Custodial Status
In its first ground, the State suggests that the trial court’s conclusion of law that appellee was in custody should be reviewed
de novo,
as opposed to the almost-total-deference standard applied by the court of appeals.
Saenz,
The Supreme Court has described how an appellate court must decide whether a person was in custody for purposes of applying
Miranda. Thompson v. Keohane,
Two discrete inquiries are essential to the [custodial] determination: first, what were the circumstances surrounding the interrogation; and second, given those circumstances, would a reasonable person have felt he or she was not at liberty to terminate the interrogation and leave. Once the scene is set and the players’ lines and actions are reconstructed, the court must apply an objee-tive test to resolve the “ultimate inquiry”: “[was] there a ‘formal arrest or restraint on freedom of movement’ of the degree associated with a formal arrest.” The first inquiry, all agree, is distinctly factual. State-court findings ... attract a presumption of correctness .... The second inquiry, however, calls for application of the controlling legal standard to the historical facts. This ultimate determination, we hold, presents a “mixed question of law and fact” qualifying for independent review.
Thompson,
This Court has similarly described the standard of review that should be applied to a trial court’s determination that a person was in custody for purposes of
Miranda.
This Court has explained that a reviewing court applies a bifurcated standard of review to a trial court’s findings of fact and conclusions of law regarding a motion to suppress.
Guzman v. State,
When the posture of a case does not present issues of pure fact, or of mixed questions of law and fact that turn on credibility or demeanor, and presents only questions of the validity of the trial court’s ‘legal rulings’ — [including a Miranda custody determination] — an appellate court’s review is de novo.
Id.; see also Herrera,
In
Alford v. State,
this Court further explained that, “[i]f credibility and demeanor are not necessary to the resolution of an issue, whether a set of historical facts constitutes custodial interrogation ... is subject to
de novo
review because that is an issue of law[.]”
The ultimate legal determination of whether an individual was in custody requires an appellate court to take the facts, as assessed for weight and credibility by the trial court, and then to make a legal determination as to whether those facts amount to custody under the law.
Ortiz,
III. Remand is Necessary for Completion of Findings of Fact
The State’s first ground also argues that the appellate court erred by failing to remand the case for more complete findings by the trial court. In its second ground, the State contends that the court of appeals erred by determining that the facts establish that appellee was in custody under the fourth situation in
Dowthitt v. State,
A. Findings Made By Trial Court Were Inadequate
Because findings of fact were requested by the State, the losing party on the motion to suppress, the trial court was obligated to make findings that were adequate for the appellate court to decide the legal determinations in the case. “[U]pon the request of the losing party on a motion to suppress evidence, the trial court shall state its essential findings.”
State v. Elias,
As we have held in several recent decisions, an appellate court must abate for additional findings of fact when a party has requested findings of fact and the findings that are made by a trial court are so incomplete that an appellate court is unable to make a legal determination.
See Elias,
B. Omitted Findings Would Affect Ultimate Legal Conclusion
The parties dispute whether the court of appeals erred by determining that the facts established that appellee was in custody at the time of his oral statements to Officer Sanders. A person is in custody only if, under the circumstances, a reasonable person would believe that his freedom of movement was restrained to the degree associated with a formal arrest.
Stansbury v. California,
(1) when the suspect is physically deprived of his freedom of action in any significant way, (2) when a law enforcement officer tells the suspect that he cannot leave, (3) when law enforcement officers create a situation that would lead a reasonable person to believe that his freedom of movement has been significantly restricted, and (4) when there is probable cause to arrest and law enforcement officers do not tell the suspect that he is free to leave.
Dowthitt,
Although the court of appeals focused only on the fourth situation, our review of the record indicates that the second situation may also be implicated here because, at one point during his testimony, Officer Bintliff testified that after he placed appel-lee in the patrol car, he told appellee that he could not leave. If the trial court believed that testimony, then that might affect the ultimate legal determination of whether a person would reasonably believe that he was not free to leave. If the trial court’s future findings determine that Officer Bintliff told appellee that he was not free to leave, then this case could be similar to the second situation in
Dowthitt
based on evidence that appellee was in the back seat of the patrol car, was not free to leave, and was told that he could not leave.
See Dowthitt,
We also conclude that the fourth situation of
Dowthitt
may be implicated, although for different reasons than those described by the court of appeals. Contrary to the holding by the court of appeals, an officer does not necessarily manifest to a suspect that there is probable cause to arrest him merely by silently placing him in the back of a patrol car when there is probable cause to arrest. Rather, a reviewing court must determine whether, under all of the objective circumstances, a reasonable person would have believed that he was under restraint to the degree associated with an arrest.
See Shiflet v. State,
Consideration of the entire circumstances includes a determination of the length of time that the person was in a patrol car.
See Dowthitt,
In assessing whether appellee was in custody under
Dowthitt,
a future finding about what Officer Bintliff told appellee would likely affect the ultimate determination of custody.
Compare Ortiz,
382
We hold that the court of appeals erred by determining, in the absence of adequate fact-findings to reflect the totality of the circumstances, that the officer’s silence at the moment he placed appellee in the!patrol car manifested to appellee that he was in custody. The court of appeals should have abated the case for more complete findings of fact. We sustain the State’s first ground.
IV. Conclusion
The court of appeals erred in applying a deferential standard of review to ⅛ trial court’s conclusion of law that appellée was in custody at the moment he made the challenged statements. Additionally, the trial court’s findings describing the entire circumstances surrounding the interrogation were inadequate from which to reach a legal conclusion on the question of custody. Accordingly, we reverse the judgment of the court of appeals and remand this case to that court with instructions for abatement to the trial court for further proceedings.
Notes
. We note that the record is unclear as to what Officer Bintliff said to appellee when he placed appellee in the back seat of his patrol car. The record from the hearing on the motion to suppress shows the following:
[Defense Counsel]: And when you put him in the back of your car, you told him that he could not leave, for him to wait there and stay there until further investigation continued?
[Officer Bintliff]: Yes, sir.
[Defense Counsel]: Did you tell him at that point that he was suspected of DWI?
[Officer Bintliff]: No, I did not.
[Defense Counsel]: Did you tell him that he was suspected of public intoxication?
[Officer Bintliff]: No.
. The trial court made twelve findings of fact. The trial court’s first five findings state that (1) "Officer Bintliff was dispatched to a restaurant establishment ... because of a disturbance [and he] "did not observe any specific criminal act”; (2) "Officer Bintliff was given a description of two males, one wearing a white shirt and the other a green shirt”; (3) appellee "was the male wearing the white shirt and was sitting on the driver's seat with the key in the ignition and the vehicle in the reverse gear”; (4) "Officer Bintliff did not testify that a crime was about to be committed”; and (5) appellee "was identified and placed in the back seat of Officer Bintliff’s patrol car for suspicion of DWI.” The trial court’s sixth finding determined that appellee “was not free to leave the police vehicle and was under arrest.” Numbers seven through twelve are consistent with the testimony by Officer Sanders described above, and, therefore, those findings are not repeated here.
. The State's petition presents two grounds:
1. Whether the Thirteenth Court of Appeals applied the wrong standard of review by affording almost total deference to the trial court’s determination as to when the suspect was in custody, in view of the fact that there was no dispute concerning the facts surrounding the detention, nor did the trial court indicate in its findings of fact, or otherwise, that it disbelieved any of the historical facts related by the officers involved?
2. Whether the Thirteenth Court of Appeals erred by concluding that a driver temporarily detained on suspicion of DWI and placed in the back of a patrol car during a brief investigation is in custody for purposes of Miranda simply because the detaining officer did not inform the driver of the reason for the detention and that he was not under arrest?
. In the absence of any findings of fact, either because none were requested or none were spontaneously made by the trial court, we must presume that the trial court implicitly resolved all issues of historical fact and witness credibility in the light most favorable to its ultimate ruling.
State v. Elias,
. The court of appeals did not discuss the first and third Dowthitt situations. We observe, however, that the trial court’s future finding as to whether appellee was told that he could not leave would likely affect the court's analysis on those categories and the overall analysis of the case.
. The trial court is, of course, limited to making findings based on the facts that currently appear in the record.
See State
v.
Elias,
. It may be that the court of appeals’s ultimate legal conclusion in this case was correct; we, however, restrict our holding to address the court of appeals's error in attempting to reach that legal conclusion in the absence of adequate fact-findings from the trial court.
