AFFIRMED
A jury convicted Trevor John Proby of assault family violence for intentionally,
knowingly, or recklessly causing bodily injury to his wife, S.P. 1 See TEX. PENAL CODE
§ 22.01(a)(1), (b). The trial court assessed Proby’s punishment at confinement for 365 days in the
Guadalupe County jail, suspended his sentence, and placed him on community supervision for 24

months. In three issues on appeal, Proby argues that his trial counsel (1) violated his autonomy to
assert his innocence, (2) rendered ineffective assistance by failing to object on multiple occasions,
failing to request a limiting instruction, and failing to request a defensive instruction in the jury
charge, and (3) committed errors whose cumulative effect requires reversal. We affirm.
BACKGROUND
Proby and S.P. were together for 19 years and have two daughters, “Bailey” and “Bri.” 2
On June 18, 2023, Father’s Day, the family spent the afternoon fishing and playing at a creek near
their home. Bailey, then eleven years old, recalled Proby “drinking a lot that day” and becoming
“really angry.” S.P. confirmed that Proby “drank most of the time when he was awake.” At one
point, Proby yelled at S.P., threw her fishing pole in the water, then ended the outing because he
“didn’t want to be with her attitude anymore.”
S.P. drove the family to Zuehl Airport, a small aviation community about a mile from the
creek. As she drove along the gravel taxiway toward their airplane hangar, Proby abruptly shifted
the moving vehicle into park from the passenger seat. The car “jerked forward” and ground to a
halt. Proby removed the key from the ignition and exited the vehicle, but quickly returned when
he saw S.P. searching for her spare key. He grabbed her arm, slammed her wrist into the shifter,
and repeatedly struck her in the head, briefly rendering her unconscious.
Upon witnessing their father “beating [their] mom,” Bailey and Bri ran in opposite
directions screaming for help. When S.P. regained consciousness, she called out to Bri, and made
her escape. As S.P. ran to Bri, Proby got behind the wheel and sped toward Bailey, who began
“freaking out” and hid under a tarp. From her hiding place, she saw S.P. and Bri running away

authority to disguise parties’ identities in appropriate circumstances in other cases”), 9.10(a)(3).

“after [Proby] tried to run them over.” Bri “was scared [Proby] was going to hit [them] with the
car” as he sped toward them. S.P. testified that Proby came within a few feet of striking Bri, adding:
“If she had tripped, things would be much different.”
S.P. and Bri took refuge in an acquaintance’s home near their hangar, where Bailey soon
joined them. Proby “sped off” to his friend’s hangar, then visited his three-year-old daughter and
her mother later that evening.
Bailey and Bri described S.P.’s injuries as “knots on [S.P.’s] head and bruises everywhere,”
and “[a] big bump on [S.P.’s] forehead.” S.P. photographed her injuries but did not immediately
report the assault. She “was afraid of [Proby] escalating” and “was broken” by his physical and
emotional abuse. She separated from Proby in December 2023 and reported the assault in April
2024 to Deputy Christopher Trinidad with the Guadalupe County Sheriff’s Office.
At trial, S.P., 13-year-old Bailey, and nine-year-old Bri provided consistent accounts of the
assault and surrounding circumstances. After presenting three witnesses, Proby testified in his own
defense. According to Proby, he and S.P. were “bickering back and forth” as they left the creek.
He “grabbed the keys real fast” out of the ignition because “[S.P.] was drunk and [he] needed to
stop the vehicle.” Then “a hand battle over the keys” ensued. S.P. “started biting [his] head,
scratching [him], and she pulled [his] collar,” which “was very traumatic.” On cross-examination,
he stated for the first time: “I didn’t hit my wife.”
RIGHT TO MAINTAIN INNOCENCE AT TRIAL
In his first issue, Proby argues that his trial counsel conceded guilt during opening
statement and closing argument in violation of McCoy v. Louisiana, 584 U.S. 414 (2018). The
Sixth Amendment guarantees to a defendant “the right to insist that counsel refrain from admitting
guilt.” McCoy, 584 U.S. at 417, 421-22; see U.S. CONST. AMEND. VI. When a defendant expressly
-3-
04-25-00501-CR
asserts that the objective of his defense is to maintain innocence of the charged criminal acts, his
lawyer must abide by that objective and may not override it by conceding guilt. McCoy, 584 U.S.
at 423.
A plea of not guilty is insufficient to preserve a McCoy complaint. See Ex parte Barbee,
616 S.W.3d 836, 845 (Tex. Crim. App. 2021). Rather, a defendant must “object[] to a concession
of guilt disregarded by counsel and court and aired before a jury during trial.” Id.; see also Bluntson
v. State, 728 S.W.3d 87, 134 (Tex. Crim. App. 2025) (“a defendant cannot simply remain silent
before and during trial and raise a McCoy complaint for the first time after trial”) (quoting Turner
v. State, 570 S.W.3d 250, 276 (Tex. Crim. App. 2018)). Here, Proby never objected, expressed
dissatisfaction with counsel’s representation, nor informed the trial court of any disagreement with
counsel’s trial strategy. See Bluntson, 728 S.W.3d at 134-35; Turner, 570 S.W.3d at 276. And
rightly so—a McCoy violation requires a showing that trial counsel conceded guilt, yet the record
is devoid of any such concession. See Rubio v. State, No. 05-18-00861-CR, 2023 WL 3749804, at
*11 (Tex. App.—Dallas June 1, 2023, pet. ref’d) (mem. op., not designated for publication).
In opening, counsel described “[a] convoluted situation,” “a troubled marriage,” and a
“horrible day in a flawed family.” He stated that both S.P. and Proby “drank alcohol to excess,”
for which there was “no excuse.” Counsel continued:
[I]t just simply came to a head in a horrific fashion in front of the children, which
there is no excuse, there is no excuse for substance abuse, and there’s no excuse for
what these poor children have been through. . . . [W]hat did occur in the car is some
conflict between them, whether it was Mr. Proby intentionally, recklessly, or
otherwise causing harm or conflict that is simply confused[.]
Counsel nevertheless expressed confidence that the jury would “be able to see that it’s not as clear
as the State is presenting.” He anticipated conflicting accounts and suggested that the pending
divorce and custody suit was S.P.’s true motive for reporting the assault.
-4-
04-25-00501-CR
In closing, counsel acknowledged that “injuries occurred” and “harm was caused,” but
conceded no criminal responsibility. Counsel’s general references to harm conceivably
encompassed the children’s emotional distress, S.P.’s bruising and swelling, and Proby’s
purported injuries. He further challenged S.P.’s and the children’s credibility, emphasized the
delayed report and fading memories, and suggested that any injuries sustained in the “hand battle
over the keys” were accidental. Viewed in context, counsel’s acknowledgment of harm was not a
concession of guilt. Proby has therefore failed to establish that counsel overrode his objective to
maintain innocence. See McCoy, 584 U.S. at 425-26; Bluntson, 728 S.W.3d at 134-35. We overrule
Proby’s first issue.
INEFFECTIVE ASSISTANCE OF COUNSEL
In his second issue, Proby contends that trial counsel rendered ineffective assistance. To
prevail on a claim of ineffective assistance of counsel, an appellant must establish counsel’s
performance was constitutionally deficient, and the deficient performance prejudiced his defense.
Strickland v. Washington, 466 U.S. 668, 687 (1984); Ex parte Lane, 670 S.W.3d 662, 671 (Tex.
Crim. App. 2023). Because the record does not establish deficient performance, we need not
address prejudice. See Hart v. State, 667 S.W.3d 774, 781 (Tex. Crim. App. 2023).
An attorney’s performance is deficient if it “falls below an objective standard of
reasonableness under the prevailing professional norms, considering the facts of the case viewed
from counsel’s perspective at the time of the representation.” Lane, 670 S.W.3d at 671 (citing
Strickland, 466 U.S. at 687-88, 690). To fairly assess a trial attorney’s conduct, reviewing courts
must “eliminate the distorting effects of hindsight” and “indulge a strong presumption that
counsel’s conduct falls within the wide range of reasonable professional assistance.” Strickland,
466 U.S. at 689; Hart, 667 S.W.3d at 781; Lane, 670 S.W.3d at 671.
-5-
04-25-00501-CR
We first address Proby’s challenge to counsel’s failure to object to: (1) Deputy Trinidad’s
explanation for victims’ delayed reporting of abuse; (2) S.P.’s description of their marriage as “a
very abusive relationship”; and (3) testimony that he accelerated the car toward his family
members “and almost hit them.” We then turn to counsel’s failure to request a limiting instruction
and defensive instructions in the jury charge. Because counsel’s reasons for the challenged conduct
are not in the record, we will assume a “strategic motivation if any can possibly be imagined.”
Garcia v. State, 57 S.W.3d 436, 440 (Tex. Crim. App. 2001) (quoting 3 Wayne R. LaFave et al.,
Criminal Procedure § 11.10(c) (2d ed. 1999)). Unless counsel’s conduct “was so outrageous that
no competent attorney would have engaged in it,” it will be deemed reasonable. See Goodspeed v.
State, 187 S.W.3d 390, 392 (Tex. Crim. App. 2005); Garcia, 57 S.W.3d at 440.
Trial counsel may reasonably decline to object to prejudicial evidence to avoid
emphasizing it, to minimize the seriousness of the offense, or to portray the defendant as honest.
Walker v. State, 676 S.W.3d 213, 226 (Tex. App.—Houston [14th Dist.] 2023, pet. ref’d). The
failure to object to proper questions and admissible testimony is not ineffective assistance. Ex parte
Jimenez, 364 S.W.3d 866, 887 (Tex. Crim. App. 2012); McCallum v. State, 311 S.W.3d 9, 16 (Tex.
App.—San Antonio 2010, no pet.). An appellant must demonstrate that the trial court would have
erred in overruling an objection had trial counsel made one. Prine v. State, 537 S.W.3d 113, 117-
18 (Tex. Crim. App. 2017); Gauna v. State, 534 S.W.3d 7, 12 (Tex. App.—San Antonio 2017, no
pet.). We review evidentiary rulings for an abuse of discretion and uphold them if they are correct
under any applicable legal theory. See De La Paz v. State, 279 S.W.3d 336, 343-44 (Tex. Crim.
App. 2009).

04-25-00501-CR
1. Lack of Objection to Deputy Trinidad’s Testimony
Proby impugns Deputy Trinidad’s qualifications to explain typical behavior of abuse
victims. Deputy Trinidad testified that victims of domestic violence may delay reporting abuse
because they fear retaliation, wish to avoid reliving the incident, or depend on their abuser’s
financial support. He described the recurring cycle of violence, apology, and temporary
reconciliation, adding that abusive relationships “usually don’t get better.”
Jurors may be unfamiliar with behaviors common among abuse victims, including
recantation and delayed, reluctant, or inconsistent reporting. See Luna v. State, 687 S.W.3d 79, 96
& n.2 (Tex. App.—Eastland 2024, pet. ref’d) (collecting cases); Kingsbury v. State, 625 S.W.3d
686, 692 (Tex. App.—Fort Worth 2021, no pet.). Expert testimony explaining the dynamics of
power and control in abusive relationships is frequently admitted under Rule 702 of the Texas
Rules of Evidence. See Luna, 687 S.W.3d at 96 & n.2; TEX. R. EVID. 702. Similarly, Rule 701
allows opinion testimony by a lay witness who possesses specialized knowledge and experience
on a subject outside the realm of common knowledge. Osbourn v. State, 92 S.W.3d 531, 536-37
(Tex. Crim. App. 2002) (“A distinct line cannot be drawn between lay opinion and expert
testimony because all perceptions are evaluated based on experiences.”). Relevant here, a police
officer may testify in either capacity, and the designation rests largely in the trial court’s discretion.
See Osbourn, 92 S.W.3d at 536-37; Acree v. State, No. 02-25-00183-CR, 2026 WL 2539775, at
*15 (Tex. App.—Fort Worth Aug. 27, 2026, no pet.) (mem. op., not designated for publication).
Although Deputy Trinidad was not designated as an expert witness under Rules 702 and
705, he was permitted to testify based on his perception and helpful for the jury to clearly
understand the testimony or determine a fact in issue. TEX. R. EVID. 701, 702, 705; Rhomer v.
State, 569 S.W.3d 664, 669 (Tex. Crim. App. 2019); Osbourn, 92 S.W.3d at 535. Indeed, Deputy
-7-
04-25-00501-CR
Trinidad’s familiarity with the cycle of violence arose from his training and firsthand experience
handling domestic violence cases, and his testimony explained S.P.’s post-assault conduct. As
such, the trial court would have properly overruled an objection lodged by trial counsel.
Counsel also could reasonably have chosen to discredit the testimony on cross-examination
without emphasizing its importance by objecting. He elicited that S.P. requested a copy of the
police report to use in the pending divorce, and that Deputy Trinidad knew only of the reported
incident rather than a pattern of violence. On this undeveloped record, Proby has not overcome the
presumption that counsel made a sound tactical choice. See Vega v. State, 610 S.W.3d 79, 84-85
(Tex. App.—San Antonio 2020, no pet.).
2. Lack of Objection to Relationship Testimony
Proby next faults counsel’s lack of objection to S.P.’s description of their marriage as “a
very abusive relationship.” Rule 404(b) precludes evidence of a crime, wrong, or other act to prove
a person’s character to show that he acted in conformity with that character on a particular
occasion. TEX. R. EVID. 404(b). However, such evidence may be admitted for other purposes when
it has relevance apart from character conformity. See id. R. 404(b); Devoe v. State, 354 S.W.3d
457, 469 (Tex. Crim. App. 2011). In prosecutions for offenses involving family violence,
“evidence of all relevant facts and circumstances that would assist the trier of fact in determining
whether the actor committed the offense” is admissible, “including testimony or evidence
regarding the nature of the relationship between the actor and the alleged victim.” TEX. CODE
CRIM. PROC. art. 38.371(b). Under article 38.371(b), extraneous-offense evidence may be used to:
(1) explain why a victim of domestic violence is unwilling to cooperate with prosecution; (2)
confirm the victim’s initial—and later recanted—statements to police; or (3) contextualize the
nature of the relationship between the victim and the assailant. See Rodriguez v. State, 678 S.W.3d
-8-
04-25-00501-CR
375, 386 (Tex. App.—Dallas 2023, pet. ref’d) (collecting cases); Williamson v. State, No. 04-20-
00268-CR, 2021 WL 4976326, at *6 (Tex. App.—San Antonio Oct. 27, 2021, pet. ref’d) (mem.
op., not designated for publication).
Here, S.P.’s testimony contextualized the nature of her relationship with Proby and
explained her reluctance to report the assault, which are permissible purposes beyond character
conformity. See TEX. R. EVID. 404(b); De La Paz, 279 S.W.3d at 342-43; McDonnell v. State, 674
S.W.3d 694, 703-04 (Tex. App.—Houston [1st Dist.] 2023, no pet.). Consequently, any objection
would have been properly overruled. Counsel likewise could have reasonably declined to object
to avoid drawing attention to S.P.’s testimony. See Straight v. State, 515 S.W.3d 553, 573-74 (Tex.
App.—Houston [14th Dist.] 2017, pet. ref’d). Accordingly, Proby has failed to overcome the
presumption that counsel’s conduct fell within the wide range of reasonable professional
assistance. See Garcia, 57 S.W.3d at 440.
3. Lack of Objection to “Extraneous” Conduct
Proby next challenges counsel’s failure to object to his wife and daughters’ testimony that
he drove toward them at a high rate of speed. Evidence of other crimes, wrongs, or bad acts may
be admitted as same-transaction contextual evidence when they are so interwoven with the charged
offense that they form an indivisible criminal transaction. Devoe, 354 S.W.3d at 469. Such
evidence is admissible because the jury is entitled to know all relevant surrounding facts and
circumstances “to the extent that it is necessary to the jury’s understanding of the offense.” Id.
(quoting Pondexter v. State, 942 S.W.2d 577, 584 (Tex. Crim. App. 1996)).
Immediately after he assaulted S.P., Proby drove the family vehicle toward her and their
daughters while the girls sought help. This conduct was inextricably intertwined with the assault
and the family’s flight, and supplied necessary context for the jury to realistically evaluate the
-9-
04-25-00501-CR
evidence and understand the charged offense. See Devoe, 354 S.W.3d at 469; Beltran v. State, 517
S.W.3d 243, 248-49 (Tex. App.—San Antonio 2017, no pet.). It further illuminated the nature of
their relationship, the charged offense, and S.P.’s delayed reporting, and rebutted Proby’s accident
defense. See TEX. R. EVID. 404(b); Inthalangsy v. State, 634 S.W.3d 749, 756-57 (Tex. Crim. App.
2021). It was therefore admissible as same-transaction contextual evidence and for purposes apart
from character conformity. Because the trial court would have properly overruled a Rule 404(b)
objection, counsel’s omission does not constitute deficient performance.
4. Failure to Request a Limiting Instruction
Proby likewise criticizes counsel’s failure to request a limiting instruction. “The failure of
trial counsel to request a limiting instruction is not, by itself, ineffective assistance.” Straight, 515
S.W.3d at 573. “Although hindsight speculation may suggest a limiting instruction of some nature
should have been given, a reasonable explanation for counsel’s actions can be that, as a trial tactic,
requesting a limiting instruction may have highlighted the issue.” Id. Importantly, no limiting
instruction is required for same-transaction contextual evidence. Devoe, 354 S.W.3d at 471;
Wilson v. State, 419 S.W.3d 582, 593-94 (Tex. App.—San Antonio 2013, no pet.). Accordingly,
the evidence that Proby accelerated toward his family members did not warrant a limiting
instruction because it was admissible as same-transaction contextual evidence. See Devoe, 354
S.W.3d at 471. As to the remaining evidence at issue, counsel could have reasonably forgone a
limiting instruction to avoid lending it undue prominence. See Hart, 667 S.W.3d at 783.
5. Failure to Request Defensive Instructions
To demonstrate deficient performance based on trial counsel’s failure to request a
defensive jury instruction, an appellant must first show that he was entitled to such an instruction.
Id. at 782. Even if the appellant was entitled to a defensive instruction, “the decision to forgo such
- 10 -
04-25-00501-CR
an instruction may not be objectively unreasonable, as these decisions are frequently grounded in
trial strategy.” Id. “[J]ust because a competent defense attorney recognizes that a particular defense
might be available to a particular offense, he or she could also decide it would be inappropriate to
propound such a defense in a given case.” Id. (quoting Vasquez v. State, 830 S.W.2d 948, 950 n.3
(Tex. Crim. App. 1992) (per curiam)).
Proby argues that the jury should have been instructed on the laws of self-defense and
necessity. See TEX. PENAL CODE §§ 9.22, 9.31. Section 9.31 of the Penal Code permits the use of
force against another when and to the degree the actor reasonably believes the force is immediately
necessary to protect against another’s use or attempted use of unlawful force. Id. § 9.31. Pursuant
to section 9.22, conduct that is otherwise criminal is justified if:
(1) the actor reasonably believes the conduct is immediately necessary to avoid
imminent harm;
(2) the desirability and urgency of avoiding the harm clearly outweigh, according
to ordinary standards of reasonableness, the harm sought to be prevented by
the law proscribing the conduct; and
(3) a legislative purpose to exclude the justification claimed for the conduct does
not otherwise plainly appear.
Id. § 9.22. Necessity and self-defense are “confession-and-avoidance defense[s] requiring the
defendant to admit to his otherwise illegal conduct.” Maciel v. State, 631 S.W.3d 720, 723 (Tex.
Crim. App. 2021); Jordan v. State, 593 S.W.3d 340, 343 (Tex. Crim. App. 2020). A defendant
cannot simultaneously invoke confession-and-avoidance defenses and flatly deny the charged
conduct. Maciel, 631 S.W.3d at 723; Jordan, 593 S.W.3d at 343. Especially for a necessity
instruction, a defendant must “essentially admit[] to every element of the offense, including the
culpable mental state.” Maciel, 631 S.W.3d at 723 (quoting Shaw v. State, 243 S.W.3d 647, 659
(Tex. Crim. App. 2007)).
- 11 -
04-25-00501-CR
Proby’s purported entitlement to necessity and self-defense instructions presupposes that
he admitted to intentionally, knowingly, or recklessly causing bodily injury to S.P. See TEX. PENAL
CODE § 22.01(a)(1). But, as set forth above, Proby denied culpability at trial and counsel’s tactics
comported with his defense objective. See McCoy, 584 U.S. at 422-23. He has thus failed to
demonstrate that self-defense and the defense of necessity were raised by the evidence at trial. See
Maciel, 631 S.W.3d at 723; Villagran v. State, No. 04-22-00261-CR, 2024 WL 172596, at *3-4
(Tex. App.—San Antonio Jan. 17, 2024, no pet.) (mem. op., not designated for publication). And
even assuming the evidence raised such defenses, counsel could have reasonably determined that
arguing self-defense and necessity would be inconsistent with Proby’s primary defensive strategy
and in turn create a credibility issue with the jury. See Hart, 667 S.W.3d at 784. On this
undeveloped record, counsel’s omission was not “so outrageous that no competent attorney would
have engaged in it.” See Hart, 667 S.W.3d at 783; Villagran v. State, No. 04-22-00261-CR, 2024
WL 172596, at *3 (Tex. App.—San Antonio Jan. 17, 2024, no pet.) (mem. op., not designated for
publication) (quoting Hart, 667 S.W.3d at 783). Therefore, counsel was not ineffective for
declining to request defensive instructions in the jury charge. See id. at 783; Villagran, 2024 WL
172596, at *4.
We overrule Proby’s second issue.
CUMULATIVE ERROR
Finally, Proby contends that the cumulative effect of his trial counsel’s deficient
performance warrants a new trial. The cumulative error doctrine provides relief only when
constitutional errors so fatally infect the trial that they render the trial fundamentally unfair.
Estrada v. State, 313 S.W.3d 274, 311 (Tex. Crim. App. 2010) (citing United States v. Bell, 367
F.3d 452, 471 (5th Cir. 2004)). Non-errors may not in their cumulative effect cause reversible
- 12 -
04-25-00501-CR
error. Collins v. State, No. 04-20-00139-CR, 2022 WL 527668, at *18 (Tex. App.—San Antonio
Feb. 23, 2022, no pet.) (mem. op., not designated for publication) (citing Chamberlain v. State,
998 S.W.2d 230, 238 (Tex. Crim. App. 1999)). Because Proby has not established that trial counsel
was ineffective in any respect, there is no cumulative error. See id.; Poor v. State, 715 S.W.3d 15,
44 (Tex. App.—Eastland 2024, pet. ref’d). We overrule Proby’s third issue.
CONCLUSION
We affirm the judgment of the trial court.
