NUMBER 13-19-00274-CR
COURT OF APPEALS
THIRTEENTH DISTRICT OF TEXAS
CORPUS CHRISTI – EDINBURG
EDUARDO CHAPA, Appellant,
v.
THE STATE OF TEXAS, Appellee.
On appeal from the 341st District Court
of Webb County, Texas.
MEMORANDUM OPINION
Before Justices Hinojosa, Perkes, and Tijerina
Memorandum Opinion by Justice Perkes
Appellant Eduardo Chapa appeals the trial court’s order denying post-conviction
DNA testing. 1 We affirm.
1This case is before this Court on transfer from the Fourth Court of Appeals in San Antonio pursuant
to a docket-equalization order issued by the Supreme Court of Texas. See TEX. GOV’T CODE ANN. § 73.001.
I. FACTUAL AND PROCEDURAL BACKGROUND
On May 31, 2005, Chapa was indicted on murder and felon in possession of a
firearm charges. See TEX. PENAL CODE ANN. §§ 19.02, 46.04. At a jury trial, Chapa
admitted to stabbing the complainant, Abel Garza, eleven times and shooting him twice
thereafter; Chapa claimed his actions were done in self-defense. Chapa was convicted
and sentenced to fifty years’ imprisonment. Chapa appealed his conviction, and our sister
court affirmed the trial court’s judgment. See Chapa v. State, No. 04-08-00374-CR, 2009
WL 1405925, at *1 (Tex. App.—San Antonio May 20, 2009, no pet.) (mem. op., not
designated for publication).
On March 26, 2018, Chapa filed a pro se motion for DNA testing pursuant to article
64.01 of the Texas Code of Criminal Procedure, and the trial court appointed him counsel.
See TEX. CODE CRIM. PRO. ANN. art. 64.01. After reviewing the filed briefs and hearing
arguments of counsel, the trial court denied Chapa’s motion on May 6, 2019, and made
several findings of fact:
1. Evidence (a knife) exists and is in a condition making DNA testing
possible;
2. The evidence 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 way;
3. There is a reasonable likelihood that the evidence contains biological
material suitable for DNA testing;
The Court further finds that:
4. Identity is/was not an issue in the underlying case.[2]
Because this is a transfer case, we apply the precedent of the San Antonio Court of Appeals to the extent
it differs from our own. See TEX. R. APP. P. 41.
2At the hearing, Chapa’s counsel acquiesced that existing precedent on the issue of identity was
unfavorable to the defendant but urged the trial court “to go against precedent.” See Lyon v. State, 274
S.W.3d 767, 769–70 (Tex. App.—San Antonio 2008, pet. ref’d).

See id. art. 64.04. This appeal followed. See id. art. 64.05.
II. CHAPTER 64 MOTION
In a single issue, Chapa challenges the trial court’s denial of his Chapter 64 motion.
A. Standard of Review and Applicable Law
The purpose of DNA testing under Chapter 64 of the Texas Code of Criminal
Procedure is to provide an avenue by which a defendant may seek to establish his
innocence by excluding himself as the perpetrator of the offense. See Hall v. State, 569
S.W.3d 646, 655 (Tex. Crim. App. 2019); Blacklock v. State, 235 S.W.3d 231, 232–33
(Tex. Crim. App. 2007). To be entitled to post-conviction DNA testing, a convicted person
must satisfy all the applicable requirements of Chapter 64, including showing “by a
preponderance of the evidence that . . . the person would not have been convicted if
exculpatory results had been obtained through DNA testing.” TEX. CODE CRIM. PROC. art.
64.03(a)(2)(A); see Hall, 569 S.W.3d at 655. “This means that a convicted person must
show a greater than 50% chance that he would not have been convicted if exculpatory
results from the requested DNA testing had been available at trial.” Hall, 569 S.W.3d at
655 (citing Reed v. State, 541 S.W.3d 759, 774 (Tex. Crim. App. 2017)). “[T]he convicted
person’s burden will not be satisfied ‘if the record contains other substantial evidence of
guilt independent of that for which the movant seeks DNA testing.’” Id. at 656 (quoting
Swearingen v. State, 303 S.W.3d 728, 736 (Tex. Crim. App. 2010)).
The trial court entered a non-favorable finding here. Thus, we apply a bifurcated
standard of review, affording almost total deference to the trial court’s resolution of
historical facts and mixed questions that turn on credibility and demeanor, but we review
de novo mixed questions that do not turn on credibility and demeanor and questions of
3
law. Dunning v. State, 572 S.W.3d 685, 692 (Tex. Crim. App. 2019) (citing Rivera v. State,
89 S.W.3d 55, 59 (Tex. Crim. App. 2002)).
B. Analysis
The Chapter 64 statute enumerates the following requirements that are relevant to
the context of Chapa’s motion:
(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;
(B) there is a reasonable likelihood that the evidence contains
biological material suitable for DNA testing; and
(C) 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.
TEX. CODE CRIM. PRO. ANN. art. 64.03(a)(1)–(2).
The parties do not dispute that the knife, the evidence in question, still exists, is in
a condition making DNA testing possible, and has been subjected to an appropriate chain
of custody, see id. art. 64.03(a)(1)(A), or that “there is a reasonable likelihood that the
4
evidence contains biological material suitable for DNA testing.” Id. art. 64.03(a)(1)(B). The
parties instead disagree as to whether “identity was or is an issue in the case,” id. art.
64.03(a)(1)(C), and whether Chapa has established by a preponderance of the evidence
that he would not have been convicted if exculpatory results had been obtained through
DNA testing. See id. art. 64.03(a)(2)(A).
We find the issue of identity to be dispositive in this case. Chapa specifically seeks
DNA testing to show that Garza was the aggressor and that he acted in self-defense.
However, when a defendant raises a self-defense claim, the identity of the alleged
perpetrator is ipso facto not an issue. See Pegues v. State, 518 S.W.3d 529, 535 (Tex.
App.—Houston [1st Dist.] 2017, no pet.); Peyravi v. State, 440 S.W.3d 248, 249–50 (Tex.
App.—Houston [14th Dist.] 2013, no pet.); Lyon v. State, 274 S.W.3d 767, 769 (Tex.
App.—San Antonio 2008, pet. ref’d); Reger v. State, 222 S.W.3d 510, 514 (Tex. App.—
Fort Worth 2007, pet. ref’d); see also Manns v. State, No. 02-19-00312-CR, 2020 WL
1466314, at *7 (Tex. App.—Fort Worth Mar. 26, 2020, no pet.) (mem. op., not designated
for publication).
In Lyon, the appellant asserted that “DNA testing [would] prove he acted in self-
defense when he stabbed” his former wife. See Lyon, 274 S.W.3d at 769. The court
concluded
The purpose of DNA testing under article 64.03 is to provide an avenue by
which a defendant may seek to establish his innocence by excluding himself
as the perpetrator of the offense. . . . We do not believe a trial court is
required to order DNA testing under circumstances where, as here, the
defendant has admitted to being the perpetrator but seeks to establish an
affirmative defense. Therefore, because the identity of the person who
stabbed and killed defendant’s former wife was and is not an issue, the trial
court properly denied defendant’s motion for DNA testing.

Id. at 769–70. We find Lyon to be directly applicable and decline Chapa’s invitation to
revisit the court’s prior holding. See id.; see also Garcia v. State, 327 S.W.3d 269, 273
(Tex. App.—San Antonio 2010, pet. ref’d) (reaffirming Lyon). Chapa does not dispute that
he stabbed and shot Garza. Though Chapa testified at trial that he sustained “[a] couple
of cuts on [his] hand” at one point during the altercation, he also conceded that he had an
opportunity to drive away after disarming Garza, no one else stabbed Garza except him,
Garza was stabbed in the back, and he shot Garza twice after first stabbing him eleven
times and inflicting twelve separate “incise wounds.” See Hall, 569 S.W.3d at 655; LaRue
v. State, 518 S.W.3d 439, 446 (Tex. Crim. App. 2017); Lyon, 274 S.W.3d at 769–70.
“Here, the issue is not who committed an offense, but rather why,” and such issues “are
not identity concerns.” In re State ex rel. Villalobos, 218 S.W.3d 837, 840 (Tex. App.—
Corpus Christi–Edinburg 2007, no pet.).
Because the trial court properly found that identity was not and is not at issue, the
trial court did not abuse its discretion in denying Chapa’s motion for post-conviction DNA
testing. See Hall, 569 S.W.3d at 662; Peyravi, 440 S.W.3d at 250; Lyon, 274 S.W.3d at
770. We overrule Chapa’s sole issue.
III. CONCLUSION
We affirm the trial court’s judgment.
