OPINION
Veronica Zavala filed an application for writ of habeas corpus seeking to prevent her retrial for capital murder. The trial court held a hearing and denied relief. Zavala filed notice of appeal. In her sole point of error, she urges that further prosecution of her for capital murder is jeopardy barred. We disagree and affirm the trial court’s denial of relief.
Zavala was indicted and tried by jury for capital murder. After deliberating for two days, the jury deadlocked, and the trial court declared a mistrial. Zavala then filed her application for writ of habeas corpus. Zavala asserted in her application that although the jury did not return a formal verdict at her trial, the jury informally acquitted her by unanimously voting her “not guilty” of capital murder and was deadlocked only on the lesser included offense of murder.
At the habeas hearing, a partial statement of facts from Zavala’s trial was introduced. It shows the jurors returning to the courtroom after the presiding juror sent a note *869 indicating that the jury could not and would not reach a unanimous decision. 1 When questioned by the court, the presiding juror said, “we can reach a decision on one of the charges.” When the judge asked whether they could reach a decision “on the case itself,” the presiding juror said, “No.” The trial judge refused Zavala’s request to ask the jury if they had reached a decision on capital murder. The trial judge also refused Zavala’s request to have the jury return to the jury room to make a decision on one of the charges. 2 The State then requested a mistrial “based on the foreman’s presentation,” and the trial court granted the State’s motion. The jury did not return any verdict form.
At the habeas corpus hearing, four of the jurors who served at Zavala’s trial testified. Two jurors, including the presiding juror, testified that all twelve jurors had unconditionally voted for “not guilty” on the capital murder charge and that the jurors became deadlocked while deliberating the murder charge.
Two other jurors, Yolanda Cisneros and Catherine Helmer, contradicted this testimony. They testified that they had not agreed to return a “not guilty” verdict on capital murder. They explained that the jurors had deliberated but could not agree whether Za-vala was guilty of capital murder. When the jurors were split eight to four for guilty on capital murder, the jurors agreed to vote Zavala “not guilty” of capital murder if the others would find Zavala “guilty” of murder. The jurors took a vote and all twelve conditionally voted Zavala “not guilty” of capital murder. But, when the other jurors then refused to vote Zavala “guilty” of murder, they withdrew their “not guilty” votes for capital murder. Later, when the jury notified the judge that they were deadlocked, the trial court granted a mistrial.
Juror Yolanda Cisneros testified, “I told the rest of the jurors, [the split vote on murder] would void my tentative vote of ‘not guilty’ of the capital murder charge.” Juror Catherine Helmer testified that the vote had been eight to four for “guilty” on capital murder but that the jurors conditionally agreed to vote “not guilty” so the others would vote “guilty” on the murder charge. But, “When they backed down, we backed down.” Helmer repeatedly asserted that her “not guilty” vote on capital murder was only conditional.
The presiding juror testified that he would have signed the “not guilty” of capital murder verdict form but did not do so because the trial court dismissed the jury before he realized the case was over.
The Double Jeopardy Clause prohibits a second trial following acquittal.
Stephens v. State,
In
Antwine v. State,
As Zavala’s jury returned no formal verdict, she can prevail on her habeas claim only if she was informally acquitted. Applying the standard used in Antwine, we hold that the trial court did not err unless Zavala showed that her jury “plainly intended” to acquit her of capital murder.

The burden of proof in a habeas corpus hearing is on the petitioner.
Ex parte Plumb,
The case of
State ex rel. Hawthorn v. Giblin,
For the above reasons, we find that the trial court did not err in denying relief on this ground.
Zavala argues alternatively that the jury was not allowed to deliberate a sufficient time before being interrupted by the trial court. Zavala did not raise this contention in her application for writ of habeas corpus and thus may not raise the matter on appeal. Tex.R.App.P. 52(a).
Even if appellant had raised this matter at the habeas hearing, the appellate record contains no evidence which would allow us to determine whether the trial court abused its discretion in discharging the jury and declaring a mistrial after two days of deliberations.

See Galvan,
We find no error in the trial court’s ruling. The order of the trial court denying relief is affirmed.
Notes
. The presiding juror wrote, in part: “I, G.W. Crouch, as the presiding juror believe that certain jurors have taken a stand and will not reverse their decision so as to arrive at a 12-0 decision either for or against the defendant. Arguments have arisen that have some of the jurors feeling they are being attacked personally. Thus, this has caused the taking of the posture that certain jurors will not change their decision under any circumstances.”
. Tex.Code Crim.Proc.Ann. art. 37.10(a) (Vernon Supp.1995) directs the trial court to order the jury to reduce an informal verdict to proper form. The Code does not define an "informal verdict.” For a historical discussion of verdicts in Texas, see
Berghahn v. State,
. Article 37.01 provides: "A ‘verdict’ is a written declaration by a jury of its decision of the issue submitted to it in the case."
. The trial court may discharge a hung jury when the parties consent to the discharge or when the jury cannot agree and has been kept together for such time as to render it altogether improbable that it can agree.
See
Tex.Code Crim. Proc.Ann. art. 36.31 (Vernon 1981). We use the abuse of discretion standard to review the trial court’s determination that it is altogether improbable that the jury can agree.
