    THE STATE OF TEXAS                                                          STATE

    FROM THE 89TH DISTRICT COURT OF WICHITA COUNTY
    ------------
    OPINION
    ------------
    I. INTRODUCTION
    Appellant Mark Alan McCulley appeals his conviction for murder. In two
    points, McCulley contends that the trial court erred by determining that he was
    not in custody at the time he made incriminating statements to the police and by
    determining that he did not invoke his right to terminate the interview. Because
    we hold that the police cured their failure to timely advise McCulley of his rights,
    and because we hold that McCulley never unambiguously invoked his right to
    terminate the interview, we will affirm.
    II. BACKGROUND
    McCulley called the police on the night of May 20, 2007. When police
    arrived at his house, McCulley was covered in blood and his wife had been
    stabbed.   The police took McCulley to the hospital, where an ambulance
    transported his wife, who later died.      The police extensively photographed
    McCulley. From there, McCulley accompanied the police to the police station,
    where the police questioned him for almost four and one-half hours. McCulley
    eventually implicated himself in his wife’s death. Before trial, McCulley filed a
    motion to suppress the statement he made to police. The trial court held a
    suppression hearing.
    At the suppression hearing, the State called Detective Kelly Brunson of the
    City of Wichita Falls Police Department to testify. Brunson testified that he was
    trained in conducting interviews for the police department. He averred that he
    also had been trained regarding Miranda warnings and the warnings contained in
    Texas Code of Criminal Procedure article 38.22.        According to Brunson, his
    sergeant called him on the night of May 20, 2007. The sergeant sent Brunson to
    the hospital to ―view the body and to speak to [] McCulley.‖ After McCulley
    consented to the search of his house, Brunson said that he asked McCulley to go
    to the police station so that he could interview him.      Brunson testified that
    McCulley obliged and that another officer brought McCulley to the police station.
    He also said that McCulley was not a suspect at this time and that the interview
    was intended to ―gather leads and any intelligence he might have to try to find out
    2
    what happened.‖        Brunson said that the videotaped interview began shortly
    before 1:00 a.m. on May 21.
    Brunson said that as he interviewed McCulley, he had McCulley verify to
    him that he was there of his own free will, and Brunson said that McCulley freely
    answered his questions. Brunson testified, as the video of the interview played
    for the trial court, that after asking McCulley, ―is there anything that you haven’t
    talked about that might help me out on this case, anything at all that might help
    me, ― McCulley responded, ―I just want to see her,‖ and ―I just want to go to the
    hospital.‖ After telling McCulley that his wife ―was still at the hospital,‖ Brunson
    told McCulley that he could see her ―as soon as we finish here.‖
    Brunson said that during the interview, he reminded McCulley that he was
    still free to leave: ―I was just making sure that he understood that he was there
    on his own free will, that he wasn’t under arrest and he wasn’t charged with any
    offense.― Brunson testified that his specific statement was ―You’re here under
    your own free will, you still understand that, right?‖ McCulley responded, ―I would
    like to go to the hospital.‖ Brunson responded, ―Even if we let you go to the
    hospital, . . . I don’t know if we would let you see your wife right away,‖ and
    ―Now’s probably not a good time to see her.‖ When asked what would have
    happened if McCulley had gone to the hospital, Brunson said, ―I wouldn’t have let
    him see her [body].‖
    Brunson testified that after asking to go to the hospital, McCulley asked,
    ―Can I go home?‖ Brunson responded that the police were still at his house and
    3
    that he could take him there as soon as they were finished. As the interview
    continued, Brunson said that another detective stepped into the interview room.
    Brunson explained to the other detective that McCulley wanted to see his wife
    and that Brunson had told McCulley it probably wasn’t a ―good idea at this time.‖
    The detective responded that she did not think it was a good idea for McCulley to
    see his wife and also that the police would be at his home for some time.
    McCulley asked again, ―Can I go home?‖ He was told again that it was not a
    good idea. Brunson said that what the detective meant when she said that the
    police would be at McCulley’s home for a while was that the police would be
    processing crime-scene evidence and no one would be allowed in the home.
    Brunson said that even after these requests, McCulley was not a suspect at this
    time and that he was still free to leave the interview.
    By Brunson’s account, if McCulley were to leave the police station, an
    officer ―would have transported him.‖ Brunson acknowledged that McCulley was
    not wearing shoes. Brunson said that McCulley’s transportation ―would have
    been up to me.‖ An hour into the interview, Brunson asked McCulley whether he
    had committed the murder.        Later, Brunson explained to McCulley that the
    person closest to the victim is often the suspect in a murder.          Brunson
    maintained that for the majority of the nearly four and one-half hour interview,
    McCulley was free to leave at any time but that to leave would have required
    Brunson’s assistance because ―it’s . . . kind of a sneaky way out.‖ When asked
    4
    directly how McCulley would have left the police station, Brunson said, ―I would
    have to had shown him the way out.‖
    Brunson said that just before 5:00 a.m., he and McCulley read McCulley’s
    Miranda rights and his article 38.22 rights together.        Brunson averred that
    McCulley acknowledged that he understood his rights. When asked whether he
    was still willing to talk to Brunson, McCulley responded, ―Can I just go to sleep?‖
    Brunson responded, ―We need to talk. We need to get things worked out.‖ He
    told McCulley, ―You can go to sleep when we’re done.‖ But Brunson also said, ―If
    you want to invoke your rights, that’s your right also." McCulley said, ―I’ll talk to
    you,‖ and signed a waiver that he understood his rights and that he was talking to
    the police voluntarily. According to Brunson, he did not have probable cause to
    arrest McCulley even at this juncture, but McCulley ―was becoming a focus of the
    investigation.‖ At that time, another detective entered the room, and McCulley
    said, in response to the detective’s question about how he was doing, that he
    was not doing well because he was being charged with murder. The detective
    responded that McCulley was not actually being charged at this time.             But
    Brunson did testify that at this time, McCulley was no longer free to leave. The
    trial court denied McCulley’s motion to suppress.
    The video of the interview reflects many of the statements Brunson
    testified to. In the video, as the interview begins, Brunson tells McCulley that he
    is not under arrest and is not being charged with anything. Brunson also has
    McCulley verify that he knows he is there of his own free will. It is clear that
    5
    McCulley is not wearing shoes. Less than thirty minutes into the interview, the
    questions by the detectives primarily concern McCulley’s timeline of events.
    McCulley’s initial story is that his wife had left earlier that day, that he was
    watching a movie, and that his stomach got upset during the movie, so he went
    for a walk. When he arrived home from his walk, he discovered his wife lying on
    the living room floor, bleeding. According to McCulley’s initial story, she asked
    for his help and declared that she was dying.
    Brunson asks McCulley about previous physical altercations with his wife
    and a prior record of violence with her. Brunson asks several questions about
    why McCulley was not wearing shoes, what shoes he wore when he allegedly
    went for a walk during the movie, and when and where he took them off.
    Brunson physically examines McCulley by looking at the bottoms of his feet,
    looking at his hands, and lifting up his shirt and examining his torso. Brunson
    questions McCulley about cuts on his hands. Each time McCulley asks to go
    home or to the hospital, Brunson’s responses, although couched in terms of that
    not being a ―good idea‖ or not ―right now,‖ were statements suggesting that
    McCulley could eventually go to those places, but not during the time the
    interview was being conducted. At one moment, McCulley asks ―when‖ he can
    go to the hospital. Brunson responds, ―[A]s soon as we finish here.‖ Later, when
    McCulley asks to go home, Brunson responds similarly with, ―[W]e can take you
    there when we get finished.‖
    6
    Multiple times during the interview, Brunson asks McCulley whether things
    had gotten ―out of hand,‖ and ―[D]id you do this?,‖ and he tells McCulley that the
    person closest to the victim is usually the suspect.       Multiple detectives ask
    McCulley about the whereabouts of a particular knife. Multiple detectives also
    state to McCulley that his timeline does not make sense.
    In the interview, two detectives other than Brunson also question
    McCulley.   The first of the two question him before he was ever given any
    warnings. She asks him about violence in his relationship. The detective also
    tells McCulley that, according to his timeline, he would have been leaving the
    movie during its climactic moment. She tells him directly that his timeline does
    not make sense.       After almost four hours, Brunson and McCulley read
    McCulley’s Miranda and article 38.22 warnings together. McCulley eventually
    states that he had ―killed her‖ and had thrown the knife in a neighboring yard.
    The State introduced McCulley’s videotaped statement at trial, and a jury
    found him guilty of murder. The jury also found that McCulley acted in the heat
    of passion. See Tex. Penal Code Ann. § 19.02 (West 2011). McCulley was
    sentenced to twenty years’ incarceration. This appeal followed.
    III. CUSTODY AND THE ADMISSIBILITY OF MCCULLEY’S STATEMENT
    In his first point, McCulley contends that the trial court erred by determining
    that he was not in custody at any time during his nearly four and one-half hour
    interview with the police. McCulley does not contend in his brief that the trial
    court should have granted his motion to suppress his statement made to police
    7
    because he was in custody. But because that is the logical extension of his
    argument, we assume that he intended to argue that his statement should have
    been suppressed.
    A.      Custody
    The prosecution may not use statements, whether exculpatory or
    inculpatory, stemming from custodial interrogation of the defendant unless it
    demonstrates the use of procedural safeguards effective to secure the privilege
    against self-incrimination.   Miranda v. Arizona, 
    384 U.S. 436
    , 444, 
    86 S. Ct. 1602
    , 1612 (1966). Additionally, article 38.22 of the code of criminal procedure
    precludes the use of statements that result from custodial interrogation without
    compliance with its procedural safeguards. See Tex. Code Crim. Proc. Ann. art.
    38.22 (West 2005) (providing that no statement made as a result of a custodial
    interrogation shall be admissible against the accused in a criminal proceeding
    unless, among other things, prior to the giving of the statement, the statutory
    warnings are administered to the accused).
    Custodial interrogation is questioning initiated by law enforcement officers
    after a person has been taken into custody or otherwise deprived of his freedom
    of action in any significant way. 
    Miranda, 384 U.S. at 444
    , 86 S. Ct. at 1612. If
    an investigation is not at an accusatorial or custodial stage, a person’s Fifth
    Amendment rights have not yet come into play, and the voluntariness in waiving
    those rights is not implicated. Melton v. State, 
    790 S.W.2d 322
    , 326 (Tex. Crim.
    App. 1990).
    8
    Four factors are relevant to determining whether a person is in custody:
    (1) probable cause to arrest, (2) subjective intent of the police, (3) focus of the
    investigation, and (4) subjective belief of the defendant. Dowthitt v. State, 
    931 S.W.2d 244
    , 254 (Tex. Crim. App. 1996). Factors two and four have become
    irrelevant except to the extent that they may be manifested in the words or
    actions of police officers; the custody determination is based entirely upon
    objective circumstances. Id.; see also Stansbury v. California, 
    511 U.S. 318
    ,
    322–23, 
    114 S. Ct. 1526
    , 1528–29 (1994). Simply becoming the focus of the
    investigation does not necessarily equate to custody for purposes of determining
    whether a statement is voluntarily given. Meek v. State, 
    790 S.W.2d 618
    , 621
    (Tex. Crim. App. 1990).
    As a general rule, when a person voluntarily accompanies law
    enforcement to a certain location, even though he knows or should know that law
    enforcement suspects that he may have committed or may be implicated in
    committing a crime, that person is not restrained or ―in custody.‖ Livingston v.
    State, 
    739 S.W.2d 311
    , 327 (Tex. Crim. App. 1987), cert. denied, 
    487 U.S. 1210
    (1988). More specifically, so long as the circumstances show that a person is
    acting only upon the invitation, request, or even urging of law enforcement, and
    there are no threats, either express or implied, that he will be taken forcibly, the
    accompaniment is voluntary, and such person is not in custody. Anderson v.
    State, 
    932 S.W.2d 502
    , 505 (Tex. Crim. App. 1996), cert. denied, 
    521 U.S. 1122
    (1997). But the mere fact that an interrogation begins as noncustodial does not
    9
    prevent custody from arising later; police conduct during the encounter may
    cause a consensual inquiry to escalate into custodial interrogation. Ussery v.
    State, 
    651 S.W.2d 767
    , 770 (Tex. Crim. App. 1983).
    There are at least four general situations when a suspect’s detention may
    constitute custody: (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 arrest1 and
    law enforcement officers do not tell the suspect that he is free to leave. 
    Dowthitt, 931 S.W.2d at 255
    .     In the first through third situations, the restriction upon
    freedom of movement must amount to the degree associated with an arrest as
    opposed to an investigative detention. 
    Id. (citing Stansbury,
    511 U.S. at 
    322–23, 114 S. Ct. at 1528
    –29). Concerning the fourth situation, the officers’ knowledge
    of probable cause must be manifested to the subject, and such manifestation
    could occur if information sustaining the probable cause is related by the officers
    to the suspect or by the suspect to the officers. Id.; see Ruth v. State, 
    645 S.W.2d 432
    , 436 (Tex. Crim. App. [Panel Op.] 1979) (holding that a suspect’s
    ―statement that he had shot the victim immediately focused the investigation on
    1
    Probable cause to arrest exists when, at that moment, the facts and
    circumstances within the knowledge of the arresting officer and of which he has
    reasonably trustworthy information would warrant a reasonable and prudent man
    in believing that a particular person has committed or is committing a crime.
    Jones v. State, 
    493 S.W.2d 933
    , 935 (Tex. Crim. App. 1973).
    10
    him and furnished probable cause to believe that he had committed an offense[;]
    [a]fter that time, the continued interrogation must be considered a custodial
    one‖). Situation four, however, will not automatically establish custody; rather,
    custody is established if the manifestation of probable cause, combined with
    other circumstances, would lead a reasonable person to believe that he is under
    restraint to the degree associated with an arrest. 
    Dowthitt, 931 S.W.2d at 255
    .
    Additionally, the length of time involved is an important factor to consider in
    determining whether a custodial interrogation occurred. 
    Id. at 256.
    Here, according to Brunson, McCulley voluntarily rode with an officer to the
    police station from the hospital. Brunson’s testimony is the only evidence at the
    suppression hearing regarding McCulley’s ride to the police station.             This
    testimony indicates that McCulley was not in custody when the interview at the
    police station began.   Miller v. State, 
    196 S.W.3d 256
    , 266 (Tex. App.—Fort
    Worth 2006, pet. ref’d) (reasoning that appellant’s choice to voluntarily meet
    police at a location demonstrated          that police encounter was initially
    noncustodial). McCulley, however, was not wearing shoes and had blood on his
    clothing. At the suppression hearing, Brunson testified that in order for McCulley
    to return home or to the hospital, the police would have needed to transport him.
    When    asked    whether   McCulley    was   dependent     upon   the   police    for
    transportation, Brunson answered, ―It would have been up to me.‖ Brunson also
    averred that leaving the interrogation room would have been difficult, requiring
    knowledge of a ―sneaky way out,‖ so much so that Brunson said more than once
    11
    that he would have been required to escort McCulley out of the building. When
    taken as a whole, we conclude that McCulley was physically deprived of his
    freedom in a significant way.
    And even though the police never directly told McCulley that he could not
    leave, a reasonable person in McCulley’s situation would have believed that his
    freedom of movement had been significantly restricted.      Each time McCulley
    indicated a desire to go to the hospital or his home, the police indicated that he
    could not go to those places until the police were ―finished.‖ Furthermore, the
    police possessed probable cause that McCulley had committed the murder, and
    Brunson expressed this directly to McCulley several times during questioning.
    The questioning in the video reflects an interview primarily focused on McCulley.
    His version of his timeline was the subject of most of the questions asked by
    multiple police officers. Regarding McCulley’s statement that he had been on a
    walk only to come home and find that his wife had been stabbed, Brunson asked
    McCulley several questions about his lack of shoes and when he had taken them
    off. Brunson asked McCulley multiple times, ―Did you do this?,‖ and if things had
    gotten ―out of hand.‖ Brunson also examined McCulley’s hands, asked about
    cuts on his fingers, examined the bottoms of his feet, and even had him raise up
    his shirt to physically examine his torso.        McCulley had already been
    photographed in this same manner at the hospital before he went to the
    interrogation room. Multiple police officers directed questions to McCulley that
    focused on the murder weapon.
    12
    At one point, Brunson explained to McCulley that the person closest to the
    victim was a natural suspect. McCulley responded ―I’m probably in trouble.‖ This
    statement later served as one of Brunson’s transitions back to questioning
    McCulley about his timeline and about whether McCulley had been the one who
    stabbed his wife. McCulley was also told directly that his timeline did not make
    sense, and detectives asked him why he would leave the movie he was watching
    at such a climactic moment.      Again, all of these questions were framed by
    McCulley’s questions about when he could go home or to the hospital, and each
    time those requests were rebuffed with statements indicating that McCulley could
    not go to either of those places and, moreover, could not leave until the officers
    were finished questioning him. Police finally read McCulley his rights almost four
    hours after they brought him to the interrogation room. See 
    Dowthitt, 931 S.W.2d at 255
    –56 (reasoning that the length of time involved is an important factor to
    consider in determining whether a custodial interrogation occurred).             We
    conclude that McCulley was in custody and the focus of the police’s investigation
    well before 4:55 a.m., when police finally read McCulley his Miranda and article
    38.22 warnings. See 
    id., 931 S.W.2d
    at 254 (holding that a suspect being the
    focus of police investigation is a relevant factor in determining whether suspect is
    in custody). But our analysis does not end with this conclusion.
    B.    McCulley’s Custodial Statement
    The real question in McCulley’s first point is whether the trial court erred by
    overruling his motion to suppress his statement that was the result of custodial
    13
    interrogation without the benefit of police timely providing him with Miranda and
    article 38.22 warnings.
    1.     Standard of Review
    We review a trial court’s ruling on a motion to suppress evidence under a
    bifurcated standard of review.    Amador v. State, 
    221 S.W.3d 666
    , 673 (Tex.
    Crim. App. 2007); Guzman v. State, 
    955 S.W.2d 85
    , 89 (Tex. Crim. App. 1997).
    We give almost total deference to a trial court’s rulings on questions of historical
    fact and application-of-law-to-fact questions that turn on an evaluation of
    credibility and demeanor, but we review de novo application-of-law-to-fact
    questions that do not turn on credibility and demeanor. 
    Amador, 221 S.W.3d at 673
    ; Estrada v. State, 
    154 S.W.3d 604
    , 607 (Tex. Crim. App. 2005); Johnson v.
    State, 
    68 S.W.3d 644
    , 652-53 (Tex. Crim. App. 2002).
    2.     Midstream Miranda Warnings
    Generally, the failure to give timely Miranda warnings2 results in the
    prosecution being required to forfeit the use of any statement obtained during
    that interrogation during its case-in-chief. Missouri v. Seibert, 
    542 U.S. 600
    , 608,
    
    124 S. Ct. 2601
    , 2608 (2004); 
    Martinez, 272 S.W.3d at 620
    .           But not every
    2
    The seminal cases analyzing midstream Miranda warnings all use the
    same analysis to determine the subsequent effectiveness of both Miranda and
    article 38.22 warnings. See Carter v. State, 
    309 S.W.3d 31
    , 36 (Tex. Crim. App.
    2010) (analyzing midstream Miranda warnings and article 38.22 warnings with
    singular analysis); see also Martinez v. State, 
    272 S.W.3d 615
    , 622–23 (Tex.
    Crim. App. 2008) (same); Ervin v. State, 
    333 S.W.3d 187
    , 213–14 (Tex. App.—
    Houston [1st Dist.] 2010, pet. ref’d), cert. denied, --- S. Ct. ----, No. 10-9555,
    
    2011 WL 999357
    at *1 (U.S. June 13, 2011) (same).
    14
    violation of Miranda requires suppression of the evidence obtained; evidence is
    admissible when the central concerns of Miranda are not likely to be implicated
    and when other objectives of the criminal justice system are best served by its
    introduction. 
    Martinez, 272 S.W.3d at 624
    (citing 
    Seibert, 542 U.S. at 618
    –19,
    124 S. Ct. at 2614) (Kennedy, J., concurring).         A suspect who has once
    responded to unwarned yet uncoercive questioning is not thereby disabled from
    waiving his rights and confessing after he has been given the requisite Miranda
    warnings.   Oregon v. Elstad, 
    470 U.S. 298
    , 318, 
    105 S. Ct. 1285
    , 1297–98
    (1985). The central question when determining the admissibility of post-Miranda
    warning confessions made after Miranda violations is whether the evidence
    shows that the officer deliberately employed a two-step ―question first, warn later‖
    interrogation technique to circumvent the suspect’s Miranda protections. 
    Carter, 309 S.W.3d at 36
    . This is so because when the warnings are inserted in the
    midst of coordinated and continuing interrogation, they are likely to mislead and
    deprive a defendant of knowledge essential to his ability to understand the nature
    of his rights and the consequences of abandoning them. 
    Martinez, 272 S.W.3d at 626
    , n.20 (citing Moran v. Burbine, 
    475 U.S. 412
    , 423–24, 
    106 S. Ct. 1135
    ,
    1142 (1986)). When a question-first interrogation begins, it cannot be known
    whether the suspect will incriminate himself, but the suspect’s rights as set out in
    Miranda have already been violated. 
    Martinez, 272 S.W.3d at 624
    . And it is
    immaterial whether incriminating statements emerged from the unwarned portion
    of the interrogation. 
    Id. If a
    deliberate two-step question-first strategy has been
    15
    used, post-Miranda statements that are related to the substance of pre-Miranda
    statements must be excluded unless curative measures are taken before the
    post-Miranda statements are made. 
    Id. at 626–27.
    No curative steps were taken
    in this case.
    Here, police should have given McCulley his Miranda and article 38.22
    warnings at the moment his interview turned from an investigation to an
    interrogation.       Therefore, we must determine whether the police deliberately
    employed a two-step question-first strategy in an effort to thwart McCulley’s
    understanding of his rights.
    3.     No Deliberate Tactic by Police to Undermine Miranda
    The standard of review for a trial court’s finding of an officer’s subjective
    deliberateness in the ―question first, warn later‖ Miranda context is that the
    finding shall not be set aside unless clearly erroneous, and due regard shall be
    given to the opportunity of the trial court to judge the credibility of the witnesses.
    
    Carter, 309 S.W.3d at 38
    –39. Because the ―question of whether the interrogating
    officer deliberately withheld Miranda warnings will invariably turn on the credibility
    of the officer’s testimony in light of the totality of the circumstances surrounding
    the interrogation,‖ a factual finding regarding the officer’s credibility is entitled to
    deference on appeal and is reviewed only for clear error. 
    Id. at 39.
    Here, the trial court made the specific finding of fact at the suppression
    hearing that Brunson was a credible witness. Brunson testified that he did not
    believe that McCulley was in custody at any time during the interview. Because
    16
    the question of whether Brunson deliberately withheld warnings turns on his
    credibility and because the trial court determined he was in fact credible, we
    defer to the trial court’s determination.   Based on the trial court’s credibility
    determination, the record does not show a deliberate tactic to employ a two-step
    interrogation technique. We hold that the record fails to show that the police
    deliberately used a two-step, ―question first, warn later‖ strategy. See 
    Carter, 309 S.W.3d at 36
    ; see also 
    Ervin, 333 S.W.3d at 213
    –14) (―Because the trial
    court found credible the officers’ testimony that appellant was not in custody . . .
    even if the officers erred in their belief that she was not in custody, that error
    does not amount to a deliberate tactic to circumvent Miranda.‖).
    4.      McCulley’s Statement was Admissible
    When the two-step questioning tactic is not deliberately employed, ―the
    admissibility of any subsequent statement should turn . . . solely on whether it is
    knowingly and voluntarily made.‖ 
    Elstad, 470 U.S. at 309
    , 105 S. Ct. at 1293;
    
    Carter, 309 S.W.3d at 32
    .        Thus, the factfinder must examine all of the
    circumstances and the course of police conduct in evaluating the voluntariness of
    those post-Miranda statements. 
    Carter, 309 S.W.3d at 41
    . We must give great
    deference ―to the trial judge’s decision to admit or exclude such evidence, which
    will be overturned on appeal only where a flagrant abuse of discretion is shown.‖
    
    Id. at 42;
    see United States v. Stewart, 
    536 F.3d 714
    , 723 (7th Cir. 2008) (stating
    that when the interrogation process used was not a deliberate end run around
    Miranda, a trial court should determine ―whether the initial unwarned confession
    17
    would flunk the voluntariness standard of Elstad such that the taint would carry
    over to the second warned confession‖).
    In this case, the trial judge made specific findings that McCulley’s post-
    Miranda statement to police was voluntarily made. We find that the record and
    reasonable inferences from that record support this finding.               Brunson
    administered appropriate Miranda and article 38.22 warnings prior to McCulley’s
    statement that he had killed his wife. In the video of the interview, McCulley
    repeatedly said that he understood his rights and was willing to talk to the police.
    Thus, predicated on the legal conclusion that it was voluntarily made, we agree
    with the trial judge that McCulley’s statement was admissible. See 
    Carter, 309 S.W.3d at 37
    (holding that trial court’s finding that defendant’s statement was
    voluntarily made supported trial court’s admission of statement despite mid-
    Miranda warning). We overrule McCulley’s first point.
    IV. MCCULLEY’S RIGHT TO TERMINATE THE INTERVIEW
    In his second point, McCulley contends that the police did not honor his
    request to remain silent or to terminate the interview.
    A.     Standard of Review
    An appellate court should afford almost total deference to a trial court’s
    determination of the historical facts that the record supports, especially when the
    trial court’s fact findings are based on an evaluation of credibility and demeanor.
    Guzman v. State, 
    955 S.W.2d 85
    , 89 (Tex. Crim. App. 1997); Hollingsworth v.
    State, 
    15 S.W.3d 586
    , 591 (Tex. App.—Austin 2000, no pet.). Appellate courts
    18
    should give the same amount of deference to a trial court’s 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, 955 S.W.2d at 89
    ; Hargrove v. State, 
    162 S.W.3d 313
    , 318
    (Tex. App.—Fort Worth 2005, pet. ref’d). Appellate courts review de novo ―mixed
    questions of law and fact‖ not falling within this category. 
    Guzman, 955 S.W.2d at 89
    ; 
    Hargrove, 162 S.W.3d at 318
    . At the hearing on a motion to suppress, the
    trial court is the sole trier of fact and judge of the witnesses’ credibility and the
    weight to be given their testimony. Ramirez v. State, 
    44 S.W.3d 107
    , 109 (Tex.
    App.—Austin 2001, no pet.). The trial judge may choose to believe or disbelieve
    any or all of a witness’s testimony. 
    Id. B. Invoking
    the Right to Remain Silent
    The Fifth Amendment privilege against self-incrimination is protected
    during custodial interrogation by certain procedural safeguards delineated in
    Miranda. 384 U.S. at 
    444, 86 S. Ct. at 1612
    . These ―safeguards‖ have been
    codified in the Texas Code of Criminal Procedure. See Tex. Code Crim. Proc.
    Ann. art. 38.22.      Within these principles, the right to terminate a custodial
    interrogation is a ―critical safeguard‖ of the right to remain silent. See Michigan v.
    Mosley, 
    423 U.S. 96
    , 103, 
    96 S. Ct. 321
    , 326 (1975). No formal invocation of this
    right is necessary.    Watson v. State, 
    762 S.W.2d 591
    , 597 (Tex. Crim. App.
    1988).     If the suspect indicates ―in any manner‖ that he invokes the right to
    remain silent, the interrogation must stop.     
    Miranda, 384 U.S. at 473
    –74, 
    86 19 S. Ct. at 1627
    . But any indication that the suspect wishes to remain silent must
    be unambiguous, and interrogating officers are not required to clarify wishes that
    are ambiguous.      
    Dowthitt, 931 S.W.2d at 257
    .        An officer’s failure to stop
    custodial interrogation after an unambiguous invocation of the right to remain
    silent renders any later obtained statements inadmissible. 
    Id. ―Of course,
    when a suspect makes an ambiguous or equivocal statement it
    will often be good police practice for the interviewing officers to clarify whether or
    not he actually wants‖ to terminate the questioning. Davis v. U.S., 
    512 U.S. 452
    ,
    461, 
    114 S. Ct. 2350
    , 2356 (1994). The officer is not, however, required to ask
    clarifying questions, and if the suspect’s statement is not an unambiguous or
    unequivocal request to terminate the interview or to invoke the right to silence,
    the officers have no obligation to stop questioning him. 
    Davis, 512 U.S. at 461
    –
    62, 
    114 S. Ct. 2356
    ; Ramos v. State, 
    245 S.W.3d 410
    , 418 (Tex. Crim. App.
    2008). In determining whether the right to remain silent was unambiguously
    invoked, courts look to the totality of the circumstances. 
    Williams, 257 S.W.3d at 433
    (Tex. App.—Austin 2008, pet. ref’d).
    Here, McCulley contends that his questions about whether he could go to
    the hospital or go home, coupled with his statements that he wanted to ―go to
    sleep,‖ were sufficient to invoke his right to terminate the interview. But none of
    these statements constitute an unambiguous and unequivocal invocation of the
    right to remain silent or otherwise terminate the interview.        And each time,
    Brunson followed the statements with clarifying remarks of his own. In fact, when
    20
    McCulley ultimately told Brunson, ―I just want to go to sleep,‖ Brunson did not
    simply ignore the statement and continue questioning. Instead, Brunson sought
    to clarify McCulley’s wishes before continuing the interview. See Marshall v.
    State, 
    210 S.W.3d 618
    , 628 (Tex. Crim. App. 2006), cert. denied, 
    552 U.S. 847
    (2007) (stating that federal constitutional law does not prohibit officer from
    clarifying whether arrestee wished to waive right to remain silent); Williams v.
    
    State, 257 S.W.3d at 432
    (same). Brunson even told McCulley, ―If you want to
    invoke your rights, that’s your right, also.‖ McCulley replied, ―I’ll talk to you.‖
    Giving due deference to the factfinder’s credibility determinations, we conclude
    that the trial court did not abuse its discretion by overruling the motion to
    suppress as pertaining to any right to remain silent and admitting McCulley’s
    statement. See 
    Dowthitt, 931 S.W.2d at 257
    (holding that appellant’s statement,
    ―I can’t say more than that. I need to rest,‖ was ambiguous and indicated only
    that appellant believed that he was physically unable to continue); 
    Hargrove, 162 S.W.3d at 319
    (holding that accused’s statement that he wanted to ―terminate it‖
    was ambiguous and did not require the officer to stop questioning); Franks v.
    State, 
    90 S.W.3d 771
    , 786–87 (Tex. App.—Fort Worth 2002, no pet.) (holding
    defendant’s statement, ―I don't want to talk anymore. I’m tired,‖ was ambiguous,
    and his rights were not violated by the continuation of the interrogation). We
    overrule McCulley’s second point.
    21
    V. CONCLUSION
    Having overruled both of McCulley’s points, we affirm the trial court’s
    judgment.
