OPINION
delivered the opinion of the Court,
Appellant was convicted of capital murder and sentenced to death. We affirmed his conviction and sentence on appeal.
Prible v. State,
Appellant argues that Chapter 64 of the Code of Criminal Procedure violates the due-process rights of appellants who seek to have DNA evidence from a crime scene tested for the presence of a third party’s DNA. Appellant says he contended all along that someone else committed the murders, so the possibility that there is DNA evidence from a third party is crucial to his case. The Chapter 64 requirement that the case raise an issue of identity violates his due-process rights because it prevents him from introducing evidence that someone else committed the crime.
At the hearing on the motion for DNA testing, Appellant pointed out that the Supreme Court had recently held that a state cannot enforce a statute that prevents a defendant in a criminal trial from introducing evidence to prove that someone else committed the offense.
See Holmes v. South Carolina,
ANALYSIS
Under Article 64.03, a defendant is not entitled to DNA testing unless he first shows that unaltered evidence is available for testing; that identity was an issue in the case; that there is greater than a 50% chance that he would not have been con *468 victed if DNA testing provided exculpatory results; and that the request is not to delay the execution of the sentence. See Code of Criminal Procedure Article 64.03(a). 1
In the case relied upon by Appellant,
Holmes v. South Carolina,
Under this rule, the trial judge does not focus on the probative value or the potential adverse effects of admitting the defense evidence of third-party guilt. Instead, the critical inquiry concerns the strength of the prosecution’s case: If the prosecution’s case is strong enough, the evidence of third-party guilt is excluded even if that evidence, if viewed independently, would have great probative value and even if it would not pose an undue risk of harassment, prejudice, or confusion of the issues.
Furthermore, as applied in this case, the South Carolina Supreme Court’s rule seems to call for little, if any, examination of the credibility of the prosecution’s witnesses or the reliability of its evidence. Here, for example, the defense strenuously claimed that the prosecution’s forensic evidence was so unreliable (due to mishandling and a deliberate plot to frame petitioner) that the evidence should not have even been admitted. The South Carolina Supreme Court responded that these challenges did not entirely “eviscerate” the forensic evidence and that the defense challenges went to the weight and not to the admissibility of that evidence. Yet, in evaluating the prosecution’s forensic evidence and deeming it to be “strong” — and thereby justifying exclusion of petitioner’s third-party guilt evidence — the South Carolina Supreme Court made no mention of the defense challenges to the prosecution’s evidence. Interpreted in this way, the rule applied by the State Supreme Court does not rationally serve the end that the Gregory rule and its analogues in other jurisdictions were designed to promote, ie., to focus the trial on the central issues by excluding evidence that has only a very weak logical connection to the central issues. The rule applied in this case appears to be based on the following logic: Where (1) it is clear that only one *469 person was involved in the commission of a particular crime and (2) there is strong evidence that the defendant was the perpetrator, it follows that evidence of third-party guilt must be weak. But this logic depends on an accurate evaluation of the prosecution’s proof, and the true strength of the prosecution’s proof cannot be assessed without considering challenges to the reliability of the prosecution’s evidence. Just because the prosecution’s evidence, if credited, would provide strong support for a guilty verdict, it does not follow that evidence of third-party guilt has only a weak logical connection to the central issues in the case. And where the credibility of the prosecution’s witnesses or the reliability of its evidence is not conceded, the strength of the prosecution’s case cannot be assessed without making the sort of factual findings that have traditionally been reserved for the trier of fact and that the South Carolina courts did not purport to make in this case.

[T]he rule is “arbitrary” in the sense that it does not rationally serve the end that the Gregory rule and other similar third-party guilt rules were designed to further. Nor has the State identified any other legitimate end that the rule serves. It follows that the rule applied in this case by the State Supreme Court violates a criminal defendant’s right to have “a meaningful opportunity to present a complete defense.”
The distinguishing factor in the ease before us is that the issue in Holmes relates to a defendant’s right to present a complete and meaningful defense at trial, including evidence of third-party guilt, whereas this case involves Chapter 64 claims that arise long after the defendant has presented his defense evidence in a fair trial. 2 There is no constitutional right to post-conviction DNA testing in order to determine the presence of a third-party’s DNA. Because the holding in Holmes is based on state rules that prohibit the admission of third-party evidence at a criminal trial, it does not relate to our Chapter 64 motions for DNA testing. Additionally, Chapter 64 does not exclude all evidence of third-party guilt. Rather, the statute proscribes testing if additional DNA testing would not result in exculpatory evidence that would have altered the outcome of the trial. See Code of Criminal Procedure Article 64.03(a). If, regardless of the re- *470 suits, retesting would not show by a preponderance of the evidence that Appellant would not have been convicted, then there is no reason for the court to order the DNA testing. There is nothing unreasonable or unjust with the way Chapter 64 deals with requests for DNA testing.
Evidence of a another person’s DNA in addition to Appellant’s is not exculpatory evidence in this case due to the additional evidence presented at the trial. 3 Thus, even if the evidence was retested and determined to contain another person’s DNA in addition to Appellant’s DNA, it would not establish by preponderance of the evidence that Appellant would not have been convicted if the jury had heard that DNA from a third-party was present.
In
Bell v. State,
Finally, we reject Appellant’s argument that the Article 64.03(a)(1)(B) requirement that identity be an issue in the case is satisfied simply because he pled not guilty and claimed throughout the trial that someone else committed the murders. Under Article 64.03(b), a determination that identity was an issue in the case is not precluded based solely on a guilty or nolo contendere plea. Using the same reasoning, the issue of identity as it pertains to Chapter 64 is not raised solely by a plea of not guilty. The identity requirement in Chapter 64 relates to the issue of identity as it pertains to the DNA evidence. Therefore, if DNA testing would not determine the identity of the person who committed the offense or would not exculpate the accused, then the requirement of Article 64.03(a)(2)(A) has not been met.
CONCLUSION
We agree with the findings of the trial court and hold that Appellant’s due-process rights are not violated by the requirements of Chapter 64. Appellant’s point of error is overruled, and the decision of the trial court to deny Appellant’s motion for post conviction DNA testing is affirmed.
Notes
. Article 64.03(a) states that:
(a) A convicting court may order forensic DNA testing under this chapter only if:
(1) the court finds that:
(A) the evidence:
(i) still exists and is in a condition making DNA testing possible; and
(ii) has been subjected to a chain of custody sufficient to establish that it has not been substituted, tampered with, replaced, or altered in any material respect; and
(B) identity was or is an issue in the case; and
(2) the convicted person establishes by a preponderance of the evidence that:
(A) the person would not have been convicted if exculpatory results had been obtained through DNA testing; and
(B) the request for the proposed DNA testing is not made to unreasonably delay the execution of sentence or administration of justice.
. Because Appellant has not alleged that a constitutional violation occurred at his trial, his is a Herrera-type claim.
