OPINION ON REHEARING
Appellant’s motion for rehearing is overruled. This court’s opinion of December 16, 1999, is withdrawn, and this opinion is issued in its place.
INTRODUCTION
This is an appeal of a murder case tried to a jury. Appellant, Amador Cesario Rodriguez, complains that the trial court erred in denying his motion for continuance and motion for new trial, both of which were based on the failure of a key but unsubpoenaed witness to appear at trial. Appellant also complains that the denial of his motion for continuance and motion for new trial violated his right to due course of law under the state constitution and due process of law under the federal constitution. We affirm.
Background Facts
Appellant went to a Houston nightclub with a friend, where he met Candy Peque-ño and Monica Garza. Appellant left the club alone around 1:45 a.m. and proceeded to his car. On the way to his car, he saw Ms. Pequeño and Ms. Garza standing nearby and agreed to give them a ride to their car, which was in a restaurant parking lot across the street. After the three of them arrived by car in the restaurant’s parking lot, appellant began arguing with the occupants of a red Escort, driven by the complainant, Charles Haywood. In Mr. Haywood’s car were his friends, Jermaine and Maria McFadden, who were in the backseat, and Eddie Kelly, who was in the front passenger seat. The parking lot argument eventually escalated to the point that appellant pulled out a twelve gauge shotgun he kept in his car and fired at Mr. *565 Haywood’s car. The shot killed Mr. Haywood and injured Mr. McFadden. After the shooting, appellant fled the scene. Shortly thereafter, the Houston police arrested him.
At his murder trial, appellant claimed that the passengers of Mr. Haywood’s car were waving a gun, prompting him to shoot in self-defense. All three of the passengers in Mr. Haywood’s car denied that any of them had a gun on the night of the shooting. To establish his defense, appellant relied on his own testimony. He also intended to present the live testimony of Ms. Pequeño, one of the passengers in his car the night of the shooting, who earlier had testified before the grand jury that she saw the occupants of the red Escort waving a gun at appellant’s car. Ms. Pequeño had cooperated with appellant’s counsel in pretrial proceedings and had agreed to testify for appellant at trial. Because she had demonstrated reliability by appearing_for all three previous trial settings, appellant relied on Ms. Pequeño to appear at trial voluntarily and did not arrange for a subpoena to compel her attendance. When the trial began, however, Ms. Pequeño was nowhere to be found.
On the second day of the trial, which was a Tuesday, Ms. Pequeño still had not appeared, nor had appellant determined her whereabouts. At that point, appellant’s counsel secured a subpoena for her attendance at trial but was unable to locate her for service. Following appellant’s testimony on Thursday of the same week, appellant’s counsel moved for a continuance until the following Monday, stating that although the defense had not located Ms. Pequeño, they had made contact with her brother, who was helping them look for her. The trial court denied appellant’s motion for continuance but gave appellant the option of reopening his case if he located Ms. Pequeño by the next morning. In addition, the trial court allowed appellant, over the State’s objection, to read to the jury the testimony that Ms. Pequeño had given before the grand jury shortly after the shooting. By Friday morning, appellant still could not produce Ms. Pe-queño or state her whereabouts. With his motion for continuance denied, appellant presented Ms. Pequeno’s grand jury testimony to the jury.
The jury found appellant guilty of murder and sentenced him to thirty years’ confinement. After the trial was over, appellant finally located Ms. Pequeño. Appellant then moved for a new trial, arguing that by denying the motion for continuance, the trial court deprived him the opportunity to put on favorable testimony from a key witness, which may have to led to a different result. The trial court denied the motion for new trial.
Motion FOR Continuance
In his first point of error, appellant contends the trial court erred in denying his motion for continuance. The Code of Criminal Procedure provides that a continuance may be granted “when it is made to appear to the satisfaction of the court that by some unexpected occurrence since the trial began,
which no reasonable diligence could have anticipated,
the applicant is so taken by surprise that a fair trial cannot be had.” Tex.Code CRIm.PR0C.Ann . art. 29.18 (Vernon 1989) (emphasis added). The granting or denial of a motion for continuance is vested in the sound discretion of the trial court.
See Duhamel v. State,
Because a missing witness is a risk inherent in almost every case, the party seeking to present the witness must exercise reasonable diligence to protect against the possibility that a witness will not appear as promised. Taking appropriate measures (i.e., arranging for the timely issuance and service of a subpoena to compel the witness’s appearance at trial) is especially critical when the witness is material to the case. Failure to take the necessary steps to secure the attendance of a key witness demonstrates a lack of reasonable diligence. Here, appellant argues he was entitled to a continuance notwithstanding his failure to arrange for the issuance of a subpoena for the missing witness because she had appeared voluntarily on prior occasions and had assured him she would be available for trial. While the witness may have led appellant to believe that a subpoena was unnecessary to secure her attendance, appellant must be held ultimately responsible for his failure to seek compulsory process for a witness as important to his case as Ms. Pequeño, even if she had proved reliable and cooperative in the past.
The uncertainty surrounding Ms. Peque-no’s availability to testify at trial also constitutes sufficient grounds for the denial of appellant’s motion for continuance. The record does not indicate a probability that Ms. Pequeño could have been secured by a postponement. At the time appellant requested the continuance, he had no knowledge of Ms. Pequeno’s whereabouts. In fact, appellant informed the trial court that even Ms. Pequeno’s brother did not know where she was. Appellant’s counsel’s attempts to locate her had proven fruitless and there was no indication that she likely would have been secured if the trial were postponed. These circumstances do not present compelling grounds for a continuance.
Given appellant’s failure to arrange for the issuance of a subpoena on the witness until the second day of trial and the uncertainty of the witness’s whereabouts or availability, we cannot say the trial court abused its discretion in denying the motion for continuance. Furthermore, in light of the fact that the trial court permitted appellant to introduce Ms. Pequeno’s grand jury testimony (which was clear, supported appellant’s claim of self defense, and was not subject to any cross-examination), appellant had the opportunity to present the missing witness’s account to the jury. We find the trial court did not err in denying appellant’s motion for continuance. Appellant’s first point of error is overruled.
Motion FOR New Trial
In his second point of error, appellant asserts he was entitled to a new trial because (1) the trial court committed error by denying his motion for continuance; and (2) a material witness was kept from the court by fraud or was intentionally withheld, providing him grounds for relief under Texas Rule of Appellate Procedure 21.3(e). Having already determined that the trial court did not err in denying appellant’s motion for continuance, we will address only appellant’s rule 21.3(e) claim. 1
The granting or denying of a motion for new trial lies within the discretion of the trial court.
See Lewis v. State,
Under rule 21.3(e), a motion for new trial
must
be granted “when a material defense witness has been kept from the
*567
court by force, threats, or
fraud,
or when evidence tending to establish the defendant’s innocence has been intentionally destroyed or withheld, thus preventing its production at trial.” Tex.R.App.P. 21.8(e) (emphasis added). The “fraud” provision of this rule contemplates at least two actors — the material witness and one or more persons who keep that witness from court by fraud.
See, e.g., Dedesma v. State,
Appellant also argues that “a material defense witness [Ms. Pequeño] ... was intentionally withheld.” However, there is no evidence in the record to support this factual assertion. 4
Absent proof that Ms. Pequeño was kept from the court by fraud, or intentionally-withheld, appellant failed to establish entitlement to relief under rule 21.3(e). Therefore, we can not conclude that the trial court’s decision to deny appellant a new trial was arbitrary or unreasonable. The trial court did not abuse its discretion in refusing to grant appellant a new trial. Appellant’s second point of error is overruled.
Due Process
In his third and fourth points of error, appellant contends the trial court’s denial *568 of his motion for continuance and motion for new trial violated his right to due course of law under the state constitution and due process under the federal constitution. According to appellant, the “basic notions of fairness were violated by the trial court refusing to allow appellant to present the most important and crucial evidence to his sole argument of self-defense.”
The federal constitution and the state constitution entitle an accused to due process and due course of law, respectively.
See
U.S. Const, amend. XIV; Tex. Const, art. I, § 19. While the Texas constitution sometimes provides greater protection than the federal constitution, there is no authority holding that due course of law provides greater protection than due process.
See Safari v. State,
The proper procedural due process analysis is two-tiered.
See Ex parte Montgomery,
As to the first tier of the procedural due process analysis, a protected interest “may be either a ‘core’ interest, such as a liberty or vested property right, or an interest that stems from an independent source, such as state law.”
Perry v. Sindermann,
Next, we must determine whether sufficient procedural safeguards ensure there is no arbitrary interference with the interest. In light of the fact that the trial court gave appellant the opportunity to present his defense through Ms. Pequeno’s grand jury testimony, we question whether there was any interference at all. Notably, appellant does not contend that his subpoena power for obtaining witnesses in his favor was in any way abridged. In fact, he admits he elected not to arrange for issuance of a subpoena on Ms. Pequeño, opting instead to rely on her promise to appear. The fact that appellant’s reliance proved to be misplaced does not constitute interference with his right to compulsory process. In any event, the notice and the opportunity to be heard at the hearings for appellant’s motion for continuance and motion for new trial were sufficient procedural safeguards to protect appellant’s liberty interest. 5 Accordingly, we *569 overrule appellant’s third and fourth points of error.
The judgment is affirmed.
Notes
. Although appellant referred to rule 21.3(b), (e), and (h) in his brief, he has informed this court that he is not relying on subsections (b) or (h) and that his argument is limited to subsection (e).
. Appellant relied exclusively on "fraud” as grounds for a new trial under rule 21.3(e); he did not allege in the lower court, nor does he assert on appeal that Ms. Pequeño was kept from court by "force” or "threats.”
. It is undisputed that appellant knew of the existence of Ms. Pequeño before the trial and knew the substance of her testimony. Furthermore, despite appellant’s reliance on Ms. Pequeno’s assurances that she would appear at trial, the fact remains that appellant failed to secure a subpoena for Ms. Pequeño until the second day of trial.
. To the extent appellant is referring to the provision in rule 21.3(e) that entitles a defendant to a new trial upon a showing that "evidence tending to establish the defendant’s innocence has been intentionally ... withheld,” his argument fails. This record does not support a finding that Ms. Pequeño "intentionally withheld” evidence within the meaning of rule 21.3(e). To the contrary, the record shows that she not only gave a detailed and sworn account of the events in question to the grand jury, but also voluntarily communicated with the defense about the evidence she possessed. Appellant's real complaint is not that Ms. Pequeño withheld evidence but that she withheld her presence at trial. Mere failure of a witness to voluntarily appear for trial does not constitute "intentional withholding of evidence” under rule 21.3(e). Furthermore, to obtain relief under this provision, the defendant must demonstrate that the “intentional withholding” prevented the production of the evidence at trial. See Tex R.App.P. 21.3(e). Ms. Pequeno’s grand jury testimony was presented at triad; thus, even if appellant had made the threshold showing that evidence was intentionally withheld, he still would not have been entitled to a new trial because there is nothing in the record to establish that production of the evidence was prevented.
. Deprivation of a protected interest requires notice and an opportunity to be heard.
