MEMORANDUM OPINION1

----------

Appellant Brent Troy Bartel appeals from his conviction for aggravated 

assault on a family member with a deadly weapon and eleven-year sentence and 

his conviction for injury to a child causing bodily injury and concurrent ten-year 

sentence. Bartel argues that the evidence did not support the jury’s implicit

rejection of his insanity defense. Because we disagree, we affirm the trial court’s 

judgments.

I. LEGAL PRINCIPLES

A. AFFIRMATIVE DEFENSE

Texas presumes that a defendant is sane and that he intends the natural 

consequences of his actions. Ruffin v. State, 270 S.W.3d 586, 591 (Tex. Crim. 

App. 2008). Insanity is an affirmative defense that the defendant has the burden 

to prove by a preponderance of the evidence. See Tex. Penal Code Ann. 

§§ 2.04(d), 8.01(a) (West 2011); Tex. Code Crim. Proc. Ann. art. 46C.153(a)(2) 

(West 2006). Insanity excuses a person from criminal responsibility even though 

the State proves all elements of the offense, including mens rea, beyond a 

reasonable doubt. Tex. Code Crim. Proc. Ann. art. 46C.153(a). 

Insanity under the law is defined as a severe mental disease or defect that 

resulted in the actor not knowing that his conduct was wrong—illegal—at the time 

of the conduct charged. See Tex. Penal Code Ann. § 8.01(a); Bigby v. State, 

892 S.W.2d 864, 878 (Tex. Crim. App. 1994), cert. denied, 515 U.S. 1162 (1995). 

In other words, a defendant’s belief that his actions were morally justified does 

not equate to insanity under the law. See Ruffin, 270 S.W.3d at 592. As such, 

the affirmative defense of insanity is a legal issue, not a medical one. See 

Plough v. State, 725 S.W.2d 494, 500 (Tex. App.—Corpus Christi 1987, no pet.). 

The fact-finder’s question then is whether “the defendant factually know[s] that 

society considers this conduct against the law, even though [he], due to his 
3

mental disease or defect, may think that the conduct is morally justified.” Ruffin, 

270 S.W.2d at 592.

B. STANDARDS AND SCOPES OF REVIEW

In four issues, Bartel argues that the evidence was legally and factually 

insufficient to support the jury’s determination that he was guilty of aggravated 

assault and injury to a child in light of the admitted evidence establishing he was 

insane at the time of the offenses. Unlike challenges to the sufficiency of the 

evidence to support the elements of an offense that the State must prove beyond 

a reasonable doubt, challenges regarding an affirmative defense, which must be 

proved by a preponderance of the evidence, are amenable to legal- and factualsufficiency review under the civil standards of review. See Matlock v. State, 

392 S.W.3d 662, 667 (Tex. Crim. App. 2013).

In a legal challenge to the sufficiency of the evidence to support an 

adverse finding on an affirmative defense, we look for more than a scintilla of 

evidence that supports the implied rejection of the affirmative defense and 

disregard all evidence supporting the affirmative defense unless a reasonable 

fact-finder could not disregard that evidence. Id. at 669. If the evidence 

supporting the affirmative defense is subject to a credibility assessment, allowing 

the fact-finder to disbelieve that evidence, we will not consider that evidence in 

our legal-sufficiency review. Id. at 670. “Only if the appealing party establishes 

that the evidence conclusively proves his affirmative defense and ‘that no 

reasonable jury was free to think otherwise,’ may the reviewing court conclude 
4

that the evidence is legally insufficient to support the jury’s rejection of the 

defendant’s affirmative defense.” Id. (quoting Tanner v. Nationwide Mut. Fire Ins. 

Co., 289 S.W.3d 828, 830 (Tex. 2009)).

By challenging the factual sufficiency of the evidence to support the 

adverse finding, Bartel is asserting that the adverse finding on his affirmative 

defense was so against the great weight and preponderance of the entire body of 

admitted evidence as to be manifestly unjust. See id. at 670 n.29, 671. In this 

review, we look at all of the evidence in a neutral light while preserving the factfinder’s weight and credibility determinations. Id. at 671. We may find the 

evidence factually insufficient to support the rejection of an affirmative defense 

only “if, after setting out the relevant evidence and explaining precisely how the 

contrary evidence greatly outweighs the evidence supporting the verdict, [we] 

clearly state[] why the verdict is so much against the great weight of the evidence 

as to be manifestly unjust, conscience-shocking, or clearly biased.” Id. at 671. If 

we so conclude, the remedy is a new trial, not acquittal. See id. at 672.

II. SUFFICIENCY OF THE EVIDENCE 

TO SUPPORT JURY’S SANITY FINDING

A. ADMITTED EVIDENCE REGARDING BARTEL’S MENTAL STATE 

Bartel does not dispute that at midnight on December 12, 2012, he carved 

a large pentagram into his six-year-old son’s back with a box cutter. It is also 

undisputed that Bartel suffers from schizophrenia and that he believed he was 
5

morally justified in carving the symbol into his son’s back.2 Bartel, however, 

relies on the testimony of forensic psychologist Dr. Antoinette McGarrahan, his 

history of mental illness, and his “bizarre” behavior both before and after the 

offense to argue that the evidence, showing that he “believed he did the right 

thing,” was legally and factually insufficient to find him guilty of the offenses 

based on his affirmative defense of insanity. 

Bartel was a long-haul truck driver and was gone from the home he shared 

with his wife, Elaine, and young son, Peter,3for extended periods of time. 

Leading up to December 12, 2012, Bartel’s behavior seemed “weird” to Elaine. 

He began to tell her that “something[]” would happen in 2012. Once when Elaine 

caught Bartel staring at a sleeping Peter, Bartel said, “He looks so innocent.” He 

would frequently read the Bible, which he had not done before, and compulsively 

watched the movie “The Passion of the Christ” and the Daystar Television 

Network.4 On December 10, 2012, Bartel unexpectedly came home, stating that 

he was sick. Bartel later stated that he had “headaches, and [his] stomach felt 

like a large snake was moving through [his] intestines” that day. 

 

2Bartel, who was religious and credited numerology, believed that the end 

of the world would occur on December 12, 2012 at midnight. To save his wife, 

who he believed had engaged in sinful behavior, his blood atonement from an

innocent—his six-year-old son—was required. 

3We use aliases to refer to Bartel’s wife and son. See Tex. R. App. P. 

9.10; 2d Tex. App. (Fort Worth) Loc. R. 7.

4This was a “religious channel.” 
6

The next day, December 11, 2012, Bartel unexpectedly picked up Peter 

early from school and took him to his church,5 where he had the reverend pray 

over Peter and bless him. When the reverend asked why Bartel was adamant 

that Peter be blessed that day, Bartel said, “Tomorrow is a special day.” At 

midnight on December 12, 2012, Bartel took a box cutter and carved a large 

pentagram into Peter’s back, permanently scarring him. When Elaine heard 

Peter screaming and ran to help him, Bartel told her that he did it because “the 

wom[e]n are sinful, so, therefore, the innocent children have to sacrifice their 

blood for forgiveness.”6 After Elaine was unable to get Peter away from Bartel, 

Elaine grabbed the box cutter and ran to their neighbor for help. Both Elaine and 

Bartel called 911. 

When the police arrived, they spoke to Elaine at the neighbor’s house. 

Elaine told the officers that Peter and Bartel were still at the house and showed 

them the box cutter. The officers then went to Bartel’s house. Bartel calmly 

came out of the house and held his arms out from his side. The officers arrested 

Bartel and took him to the police station. In the patrol car, Bartel spontaneously 

told the officers he injured his son to save Elaine’s soul:

 

5Elaine rarely attended church, but Bartel took Peter with him each Sunday 

that Bartel was in town. 

6Apparently, Bartel believed Elaine had sinned based on Facebook 

photographs and videos he either had seen or had heard about in which she was 

“half naked.” 
7

I did what I had to do to save my wife’s soul. I’m 38 years old, my 

son is 6 and the date is 12/12/12. It is all about the numbers. The 

numbers are the key. My wife is a sinner and she refuses to repent. 

So the only way to save her soul is to shed the blood of an innocent 

child. 

The next day, Detective Tye Bell interviewed Bartel, who wrote a fivepage, voluntary statement after waiving his rights. See Tex. Code Crim. Proc. 

Ann. art. 38.22, § 2 (West Supp. 2016). In it, Bartel wrote that in the days before 

December 12, 2012, he came to believe that “the only way to cleanse the wicked 

is through innocent blood cleansing,” which is why he cut Peter’s back—as “a rite 

of passage for [Elaine’s] wicked sins.” He also told Bell that he knew cutting 

Peter was against “man’s law” but that he was “operating under God’s law.” 

McGarrahan examined Bartel several times before his eventual trial7 and 

had reviewed his past history of instability that began in his childhood, Bell’s 

interview with Bartel, and his jail records. Because she could not follow Bartel’s 

logic, she recorded each session, which is the first time she had done so in more 

than fifteen years. During one session she wrote that “he understands that . . . 

the act of cutting someone is wrong, but in the context in which he did it with his 

son, he felt that it was the right thing to do.” McGarrahan equated this 

knowledge as similar to understanding that shooting a person is wrong. She 

testified that Bartel “absolutely believed what he was doing was right” in order to 

 

7Bartel was found incompetent to stand trial three times before he was 

declared competent on September 24, 2015. See Tex. Code Crim. Proc. Ann. 

arts. 46B.053, 46B.054 (West 2006), art. 46B.084 (West Supp. 2016). 
8

save Elaine. In fact, he “believed that God was controlling his behavior on the 

date of the offense and there was a spiritual or end-of-world experience, the 

coming of . . . the end of times.” But she also agreed that he knew “cutting, using 

a knife and hurting another individual is wrong.” During one interview, Bartel told 

her that he “knew [he] was going to get in trouble with the legal system.” He told 

her that he called 911 not because he believed he had done something wrong 

but because Elaine convinced him that Peter’s injuries would be a problem at 

school. 

Ten other mental-health professionals also had evaluated Bartel and 

concluded that he suffers from “a severe mental illness,” schizophrenia.8 

McGarrahan testified that people who suffer from schizophrenia are capable of 

discerning right from wrong. Dr. Randy Price testified that although Bartel was 

suffering from a severe mental illness at the time of the offense, he was not 

legally insane then because he knew his conduct was against the law. In making 

this determination, Price had met with Bartel and reviewed the offense reports, 

Bell’s interview with Bartel, jail records, McGarrahan’s report, the reports of the

ten other mental-health professionals who had evaluated Bartel, Bartel’s criminal 

history, and Bartel’s childhood of neglect and abuse. 

 

8Only two of these doctors opined as to Bartel’s legal sanity on December 

12, 2012: McGarrahan and Dr. Randy Price. 
9

B. LEGAL SUFFICIENCY

Bartel argues that the evidence of his insanity was “conclusive, and no 

reasonable jury could have disagreed.” He relies on McGarrahan’s testimony 

that Bartel suffers from schizophrenia, causing his reasoning to be “skewed and 

illogical,” and on Price’s concession that “but for [Bartel’s] severe mental illness[,] 

the crime would never have occurred.” First, this argument focuses on the fact 

that Bartel has a severe mental illness, which is undisputed. While tragic, 

Bartel’s mental illness alone does not equate to his insanity under the law. See 

Plough, 725 S.W.2d at 500. Insanity as an affirmative defense to guilt requires 

that Bartel’s mental illness caused him to not know that his conduct was 

proscribed by law on December 12, 2012. See Tex. Penal Code Ann. § 8.01(a); 

Fisher v. State, 397 S.W.3d 740, 744 (Tex. App.—Houston [14th Dist.] 2013, pet. 

ref’d). 

Second, we disagree that Bartel conclusively proved his affirmative 

defense. Price testified that Bartel knew his conduct was against the law at the 

time of the offense. Further, Bartel told Bell that he knew his conduct was 

against “man’s law,” and he told McGarrahan that he knew his actions would 

result in legal trouble for him. This evidence is more than a scintilla supporting 

the jury’s rejection of the affirmative defense. See, e.g., Pham v. State, 

463 S.W.3d 660, 672 (Tex. App.—Amarillo 2015, pet. ref’d); Moranza v. State, 

913 S.W.2d 718, 724 (Tex. App.—Waco 1995, pet. ref’d). We overrule issues 

one and three.
10

C. FACTUAL SUFFICIENCY

In arguing that the jury’s rejection of his affirmative defense was against 

the great weight and preponderance of the evidence, Bartel points to 

McGarrahan’s testimony that Bartel believed his actions were right and to the fact 

that McGarrahan spent “three time[s] more time with [Bartel] than Dr. Price [and, 

therefore,] she had greater opportunity to evaluate [Bartel’s] reason for 

committing this offense.” On this record, the jury was free to credit Price’s 

testimony that Bartel knew his actions were illegal more heavily than 

McGarrahan’s statement that Bartel believed his actions were “the right thing to 

do.”9 We will not second-guess these weight and credibility determinations. See 

Matlock, 392 S.W.3d at 671. The jury also heard that Bartel recognized that his 

conduct was against the law during Bell’s interview and Price’s evaluation. This

evidence, even viewed in a neutral light, was factually sufficient to support the 

jury’s rejection of Bartel’s affirmative defense. See, e.g., Reyes v. State, 

480 S.W.3d 70, 74–76 (Tex. App.—Fort Worth 2016, pet. ref’d); McAfee v. State, 

467 S.W.3d 622, 637–39 (Tex. App.—Houston [1st Dist.] 2015, pet. ref’d); 

McCollom v. State, No. 07-00-0282-CR, 2001 WL 121933, at *10 (Tex. App.—

 

9We do not necessarily agree with Bartel and the State that this testimony 

equated to evidence that Bartel did not know his conduct was illegal at the time 

he carved Peter’s back. Indeed, Bartel’s belief that his actions were morally 

right—not morally wrong—is not evidence that he did not know the law 

proscribed his conduct. See Ruffin, 270 S.W.3d at 592. Even McGarrahan 

recognized that Bartel knew cutting another person was “wrong.” But because 

other evidence sufficiently supported the jury’s finding on Bartel’s affirmative 

defense, we need not quibble on this point.

issues two and four.

III. CONCLUSION

Although it was not disputed that Bartel suffered from a severe mental 

illness that caused him to believe his conduct on December 12, 2012 was 

morally right, the jury heard evidence that he knew his conduct was proscribed 

by law at the time of the offense, which was legally and factually sufficient to 

support its rejection of Bartel’s affirmative defense of insanity. We overrule 

Bartel’s issues and affirm the trial court’s judgments. See Tex. R. App. P. 

43.2(a).
