THOMAS JAMES MAHON, Appellant

V.

THE STATE OF TEXAS, Appellee

________________________________________________________________________

On Appeal from the 9th District Court

Montgomery County, Texas

Trial Cause Nos. 21-03-03821-CR, 21-03-03822-CR, 21-03-03823-CR

________________________________________________________________________

MEMORANDUM OPINION

The State charged Thomas James Mahon in three indictments with three 

offenses: two counts of deadly conduct discharging a firearm, third-degree felonies, 

and one count of aggravated assault with a deadly weapon, a first-degree felony. See

Tex. Penal Code Ann. §§ 22.02(a)(2); 22.05(b)(1). In cause numbers 21-03-03821-

CR and 21-03-03823-CR Mahon was charged with “knowingly discharg[ing] a 
2

firearm at or in the direction of an individual,” namely, “Chris Smith”, and separately 

“Clark Jones”. In cause number 21-03-03822-CR, Mahon was charged with 

“intentionally,knowingly, or recklessly caus[ing] bodily injury to “Jack Green,” by 

SHOOTING THE COMPLAINANT, and during the commission of said assault, the 

defendant did then and there use or exhibit a deadly weapon, to-wit: A FIREARM.”1

On August 4, 2022, the trial court held a plea hearing. In an open plea, Mahon

pleaded guilty to the offenses, the trial court accepted Mahon’s pleas and reset the 

case so a presentencing investigation report could be prepared. On December 2, 

2022, the trial court held a sentencing hearing. After testimony from Green, the trial 

court sentenced Mahon in each case; in cause number 21-03-03822-CR to 

confinement for twenty years, and in cause numbers 21-03-03823-CR and 21-03-

03821-CR to confinement for ten years to be served concurrently, and in each case 

the trial court assessed a $0 fine. 

Issues on Appeal

Mahon argues six issues on appeal. First, he contends that the sentences 

imposed by the trial court violate his due process “because [t]he Trial Court[] 

refus[ed] to consider the full range of punishment[.]”Second, he arguesthat he was 

1We have used pseudonymsto protect the privacy of several individuals who 

are mentioned in the opinion. SeeTex. Const. art. I, § 30 (granting crime victims 

“the right to be treated with fairness and with respect to the victims’ dignity and 

privacy throughout the criminal justice process”).
3

denied due process when the trial court based its decision on a criminal offense not 

listed in the indictment. Third and fourth, he argues that the twenty-yearsentence 

imposed by the trial court is “[g]rossly [d]isproportionate” and is a violation of the 

cruel and unusual punishment clause of the United States Constitution and the Texas 

Constitution. Fifth and sixth, his convictions and punishments for Aggravated 

Assault with a Deadly Weapon and his two convictions for Deadly Conduct

discharging a Firearm violated double jeopardy. We affirm.

Background

We recite only the facts necessary for the resolution of the issues on appeal. 

Mahon was arrested for shooting at police officers Green, Smith, and Jones while 

the officers were investigating a family violence call on his property. 

At the punishment hearing, Green testified that he is a police officer with the 

Montgomery County Sherriff’s Office. On March 18, 2021, he received notifications

from dispatch of multiple calls from the same generalized location, requesting police 

presence due to family violence. After finishing his current call, Green went to the 

location at around 8:30 that night. A second unit, Deputy Smith, accompanied Green. 

He described the area as “rural” with “very little artificial lighting[.]” The officers 

arrived and “pulled probably 200 yards – or 100 yards in front of the actual location 

of where the shooting occurred.” He testified that there were communication issues

from the dispatchers, that Jones was aware of a firearm on the premises and 
4

requested backup, but that Green was told only that it was a “family violence” call.

The three officers exited their vehicles and began to use their flashlight to look for 

the address of the call. Green testified if was “very dark[,]” and properties were not 

close to the roadway, but he observed three structures “further off in the distance.” 

As they approached Mahon’s gate, Jones stated he was going to call the reportee. 

Green then scanned Mahon’s property with his flashlight and observed Mahon “in a 

low ready position...with an object in his hand that I believed to be a firearm.”Green

immediately drew his weapon, he heard Mahon yell “Fuck you[,]” and a gunshot 

“went off[.]”Green said he was shot in the front part of his head. He then began 

shooting and retreated to a ditch to “obtain some type of concealment and intentional 

cover.” Green heard additional gunshots and was also hit in his leg. Green said he 

received medical treatment for gunshot wounds to his head, bicep, and leg. 

Issue One

In his first issue, Mahon argues that the trial court violated his right to due 

process by arbitrarily refusing to consider the entire range of punishment for his 

offenses. Mahon contends that the trial court was not a fair and impartial tribunal 

because the trial judge told him “the case ‘deserve[d] the maximum punishment[]’” 

at the sentencing hearing and sentenced him to the “maximum term” without 

considering a lesser sentence and without considering mitigating circumstances 

presented by Mahon. The State argues that Mahon has not shown the trial court was 
5

biased or that it arbitrarily failed to consider the full punishment range. We agree 

with the State.

The Due Process Clause of the Fourteenth Amendment provides that no State 

may “deprive any person of life, liberty, or property, without due process of law[.]”

See U.S. CONST. amend. XIV, § 1. Similarly, the Texas Constitution provides that 

“[n]o citizen of this State shall be deprived of life, liberty, property, privileges or 

immunities . . . except by the due course of the law of the land.”Tex. Const. art. I, § 

19. “The touchstone of due process is fundamental fairness.” Euler v. State, 218 

S.W.3d 88, 91 (Tex. Crim. App. 2007). Accordingly, “[t]he Constitutional mandate 

of due process requires a neutral and detached judicial officer who will consider the 

full range of punishment and mitigating evidence.”Buerger v. State, 60 S.W.3d 358, 

363-64 (Tex. App.—Houston [14th Dist.] 2001, pet. ref’d) (citing Gagnon v. 

Scarpelli, 411 U.S. 778, 786-87 (1973)). A trial court denies a defendant due process 

by arbitrarily refusing to consider the entire range of punishment for an offense. Ex 

parte Brown, 158 S.W.3d 449, 454, 456 (Tex. Crim. App. 2005). Likewise, a trial 

court denies a defendant due process when it refuses to consider mitigating evidence 

and imposes a predetermined punishment. Buerger, 60 S.W.3d at 364. However, in 

the absence of a clear showing to the contrary, a reviewing court must presume that 

the trial court was neutral and detached in sentencing the defendant and considered 

the full range of punishment. See Brumit v. State, 206 S.W.3d 639, 645 (Tex. Crim. 
6

App. 2006); Jaenicke v. State, 109 S.W.3d 793, 796 (Tex. App.—Houston [1st Dist.] 

2003, pet. ref’d) (op. on reh’g).

Here, the record does not reflect that Mahon objected to the trial court’s 

alleged failure to consider the full range of punishment at the trial court level. 

Nevertheless, Mahon argues that under the Texas Court of Criminal Appeals’

decision in Ex parte Brown, he was not required to make a contemporaneous 

objection because the evidence that the court failed to consider the full range of 

punishment was ambiguous. See 158 S.W.3d at 453 & n.3.

To preserve error for appellate review, a party must present a timely objection 

to the trial court, state the specific grounds for the objection, and obtain a ruling. 

Tex. R. App. P. 33.1(a). But as the Court of Criminal Appeals determined, Rule 33.1 

is not absolute. See Grado v. State, 445 S.W.3d 736, 739 (Tex. Crim. App. 2014). In 

Grado, the Court of Criminal Appeals provided the following guidance in 

determining whether waiver applies to the appellant’s complaint.

The general requirement that a contemporaneous objection must be 

made to preserve error for appeal is firmly established in Rule of 

Appellate Procedure 33.1. But the rule is not absolute. In Marin, we 

held that the general preservation requirement’s application turns on the 

nature of the right allegedly infringed. We separated defendants’rights 

into three categories:

• The first category of rights are those that are “widely 

considered so fundamental to the proper functioning of our 

adjudicatory process . . . that they cannot be forfeited . . . 

by inaction alone.”These are considered “absolute rights.”
7

• The second category of rights is comprised of rights that 

are “not forfeitable”—they cannot be surrendered by mere 

inaction, but are “waivable” if the waiver is affirmatively, 

plainly, freely, and intelligently made. The trial judge has 

an independent duty to implement these rights absent any 

request unless there is an effective express waiver.

• Finally, the third category of rights are “forfeitable” and 

must be requested by the litigant. Many rights of the 

criminal defendant, including some constitutional rights, 

are in this category and can be forfeited by inaction.

Rule 33.1’s preservation requirements do not apply to rights falling 

within the first two categories. Barring these two narrow exceptions, all 

errors—even constitutional errors—may be forfeited on appeal if an 

appellant failed to object at trial.

Id. at 738-39 (citations and footnotes omitted). Grado specifically decided that the 

right for the trial court to consider the appropriate punishment range falls into the 

second category and are forfeitable only by an “effective waiver[.]” Id. at 743. 

Accordingly, although Mahon failed to object at trial regarding the trial court’s 

failure to consider the entire punishment range, absent an express waiver, he did not 

waive his objection for review of this issue on appeal. See id. 

The punishment range for aggravated assault with a deadly weapon, a seconddegree felony, is two to twenty years and a fine of up to $10,000. Tex. Penal Code 

Ann. §§ 22.02(b), 12.33. Additionally, the punishment range for deadly conduct 

discharge of a firearm is two to ten years and a fine up to $10,000. See id. §§ 

22.05(b),12.34. The trial court’ssentence falls within these ranges, although it does 

impose the “maximum term,” as Mahon contends in his brief. See id. §§ 22.02(b),
8

12.33, 22.05(b), 12.34. The record reflects that the trial court heard arguments from 

both the prosecutor and defense counsel and reviewed the evidence before assessing 

punishment. During closing argument, Mahon’s attorney advised the trial court of 

several mitigating circumstances, including Mahon’s neurological and 

psychological issues, his recent medical reports, his sobriety since his arrest, his 

criminal history, and his advanced age. The trial court also reviewed letters from 

Mahon’s brother, neighbor, and bail bondsman requesting leniency. During the 

sentencing hearing, the trial court reviewed a copy of the presentence investigation 

report and heard testimony from Green regarding his injuries and the trauma he has 

experienced since the shooting. Green testified to the following regarding his and 

the other officers’ experiences after the shooting. 

[GREEN]: Well, initially it was inability to sleep. And while the 

shooting was going on and while we were walking up on the property, 

one of his neighbors has peacocks. And I know that’s weird to be 

something to infatuate on or focus on. But I kept hearing that. I would 

wake up in panics. It would consistently occur. So they started putting 

me on medication for that because I was sleeping two, three hours a 

night. And some nights I would just drink and just depend on that. So 

they started treating that. And then on July 4th -- sorry -- the week 

before July 4th, I had a -- I don’t know what the proper term would be. 

I call it a hallucination, but it’s part --it’s kind of half and half because 

I knew it wasn’t a dream, but I still had the physical responses so I could 

still see it at my apartment complex. There’s a guy inside my apartment

that --I mean, I already lived there for a year, and Isee him every night 

when I would take my dog out. But he sits on the balcony and smokes 

cigars. And when I was out there, he lit up the cigar. And I saw the

light, and I was back in Magnolia in the ditch. And whenever I looked 

down at my hand, it was covered in blood. And I panicked and hid in 

the closet until my wife could calm me down, which we were able to.
9

And it didn’t occur for another week or two until we went to July 4th 

because I was like -- kept telling myself, no, I’m good, I’m good. The

dreams at that point were no longer consistent. So we went to July 4th 

on -- it’s one of the bridges in The Woodlands. They do a fireworks 

show every year. And then that’s when I had my worst, I guess, episode.

[THE STATE]: Okay. Can you tell us a little bit about that?

[GREEN]:Yeah. So when we arrived, you know, I was already having 

problems with just being around people and just general anxiety. So I 

know we got there early. And we got -- we’re basically at the very end

of the bridge so where people wouldn’t gather, which I’m thankful that 

we did. And I was perfectly fine even with the people around. I was 

doing okay. And at that time I was on no medication other than, I 

believe, just Adderall for ADHD which I was diagnosed in the ’90s. So 

that was the only medication I was on. And the fireworks show started. 

I had no problems at the -- you know, the first couple minutes. And then

there was just one firework that just sounded like a shotgun, and I was 

there. I was back in Magnolia, but I was still consciously aware that I 

was on a bridge in The Woodlands, but I had the physical response of 

the shooting. I could see the shooting. I could see the ditch. I could see 

Smith to the left of me enough so that I was -- my wife observed it 

enough to take my pistol off of me because it got that bad. And we have

a training sergeant that works for the academy that I really don’t even 

have a relationship with. But he was working an extra job, and he road 

by on the bicycle. And I was on the street. And when I saw him ride 

by on the street while I’m shooting, I’m like what the hell is that? That’s 

what snapped me back and we took off. And that’s when I started going 

to therapy pretty consistently, and they started putting me on

antidepressants and -- or I think it’s – whateverLexapro is what they’re 

treating with at the moment.

[THE STATE]: So that was in July of 2021?

[GREEN]: July 4th exactly.

[THE STATE]:Have you continued to seek treatment from that day?

[GREEN]: Consistently.
10

[THE STATE]: Do you still do that to this day?

[GREEN]: Yes, sir.

[THE STATE]: Are you still being treated with medication for that?

[GREEN]: Yes and no. More so we keep trying and trying different 

stuff. So far the only things that have worked I’m not technically 

allowed to take per department mental policy. So it’s been a -- just a

consistent battle with trying to find something because I would say the 

main issue is just general panic disorder is what they finally or recently 

diagnosed me with. Just random panic attacks, one to two times a week 

at nighttime. And it only happens at nighttime. I don’t know why, but 

that’s the consistent issue.

[THE STATE]:And, Deputy, you know, from our conversationstoday 

that Judge has the decision to make of probation versus prison time. Is 

there anything else you want this Court to know before making that 

decision? A. Oh, man. All I can say is that I believe in the State. I 

believe in the process and whatever the judge deems fit. It’s in the 

Court’s hands. I say that you put me in a prison mentally. I believe you

need to go to prison. I spoke with the other deputies, and I was the lucky 

one even though some people say, like, hey, you know, you got shot. 

That sucks. No, no. Deputy Smith and Deputy Jones– Jones was a 

rookie at the time. He did, like, a month. That dude was going to family 

violence calls the next night. No one gave a shit about him. No one 

called him. No one asked him how he was doing. Smith calls me all the 

time. We have to do peer support through ourselves. No one truly gives 

a shit. And that’s --that’s the crappy part just because the round hit me,

so I was able to get help thankfully. And I’ve talked to all them, and 

they all agree that probation to us is a slap in the face. But, again, if 

that’s what’s ruled then that’s what’s ruled. We move forward and we 

push forward.

After receiving argument from both sides regarding the mitigating and 

aggravating factors, the court announced its sentence:

THE COURT: Mr. Mahon in Cause No. 21-03-03821-CR, the Court 

finds you guilty of the third-degree felony offense of deadly conduct 
11

and assesses your punishment at 10 years confinement in the Texas 

Department of Criminal Justice Institutional Division. I am going to 

give you credit for the time that you’ve already served.

In Cause No. 21-03-03822-CR, the Court finds you guilty of the 

second-degree felony offense of aggravated assault and assesses your 

punishment at 20 years confinement in the Texas Department of 

Criminal Justice Institutional Division. I am going to give you credit 

for the time that you’ve already served.

In Cause No. 21-03-03823-CR, the Courtfinds you guilty of the thirddegree felony offense of deadly conduct and assesses your punishment 

at 10 years confinement in the Texas Department of Criminal Justice

Institutional Division. I am going to give you credit for the time that 

you’ve already served.

I understand everything you’ve done since you were arrested, but 

there’s some criminal offenses that deserve the maximum punishment 

and this is one of them. You almost killed a police officer, and that’s 

just not something that this Court can have sympathy for. All these 

sentences will run concurrently. You’re hereby remanded to the 

custody of the sheriff of Montgomery County, Texas where you’ll be 

remanded to the Texas Department of Criminal Justice Institutional

Division where you will carry out the remainder of your sentences. 

Good luck to you, sir.

Nothing in the record suggests that the trial judge refused to consider the 

mitigating circumstances presented by Mahon’s attorney, imposed a predetermined 

punishment, or arbitrarily refused to consider the entire range of punishment in 

assessing Mahon’s sentence. Instead, the record reflects that the trial court listened 

to the arguments presented by both sides, reviewed the record before it, and 

determined a twenty-year sentence and two ten-year sentences were an appropriate 

punishment. Further, the judge’s comments during the revocation hearing 
12

demonstrate that he was aware of the range of punishment for aggravated assault 

with a firearm, and nothing in the record rebuts the presumption that he considered 

this range in assessing Mahon’s punishment. [3RR 54:6-16] We conclude, therefore, 

that Mahon has not met his burden of demonstrating that the trial court arbitrarily 

failed to consider the full range of punishment. We perceive no denial of due process 

under the state or federal constitution. Accordingly, we overrule Mahon’s first point 

of error.

Issue Two

In his second issue, Mahon argues that he was denied due process when the 

trial court based its punishment decisions on an offense not charged in the 

indictment. Focusing on the court’s comment that Mahon “almost killed a police 

officer[,]” Mahon asserts, “The trial court erred by considering extrajudicial factors 

that were not properly before the court or admitted into evidence when fashioning 

Appellant’s sentence” because he was neither indicted for, nor pleaded guilty to, an 

offense directed at a peace officer. Mahon also argues the evidence did not show he 

knew any of the complainants was a peace officer, nor that any officer was “almost 

killed[.]”

Mahon cites Eaton v. Tulsa, 415 U.S. 697, 699, 94 S. Ct. 1228, 1230 (1974), 

Garner v. Louisiana, 368 U.S. 157, 164, 82 S. Ct. 248, 252 (1961), and Schmuck v. 

United States, 489 U.S. 705, 717, 109 S. Ct. 1443, 1451 (1989), as authority for the 
13

proposition that it is a violation of due process to convict a defendant for an offense 

with which he has not charged in the indictment. But Mahon was not convicted of 

any offense for which he was not indicted. Instead, he complains that the trial court 

considered, during the punishment phase of the trial, the fact that Green was a peace 

officer. As the Court of Criminal Appeals has explained, 

“The factfinder’s role during the guilt phase is different from its role 

during the punishment phase. Unlike the guilt phase, where the 

factfinder must decide discrete factual issues, deciding what 

punishment to impose is a ‘normative process, not intrinsically 

factbound.’ Thus, what is ‘relevant’ to assessing punishment is ‘a 

function of policy rather than relevancy.’Evidence is relevant if it helps 

the factfinder decide what sentence is appropriate for a particular 

defendant given the facts of the case.” Hayden v. State, 296 S.W.3d 

549, 552 (Tex. Crim. App. 2009), citing Sims v. State, 273 S.W.3d 291, 

295 (Tex. Crim. App. 2008), and Rogers v. State, 991 S.W.2d 263, 265 

(Tex. Crim. App. 1999).

Mahon did not object to the admission of evidence that Green was a peace 

officer, nor did he object to the trial court’s statement during sentencing referring to 

the fact Green was a peace officer. As indicated above, it is generally necessary for 

a defendant to make a timely and specific objection in the trial court in order to 

preserve an issue for appellate review. See Tex. R. App. P. 33.1(a)(1). That said, 

even if the issue had been preserved, Texas law permits trial courts to consider a 

wide array of evidence during the punishment phase of a trial:

Regardless of the plea and whether the punishment be assessed by the 

judge or the jury, evidence may be offered by the state and the 

defendant as to any matter the court deems relevant to sentencing, 

including but not limited to the prior criminal record of the defendant, 
14

his general reputation, his character, an opinion regarding his character, 

the circumstances of the offense for which he is being tried, and, 

notwithstanding Rules 404 and 405, Texas Rules of Evidence, any other 

evidence of an extraneous crime or bad act that is shown beyond a 

reasonable doubt by evidence to have been committed by the defendant 

or for which he could be held criminally responsible, regardless of 

whether he has previously been charged with or finally convicted of the 

crime or act.

Tex. Code Crim Proc. Ann. art. 37.07 § 3(a)(1).

“Of course, neither the statute’s demonstrative list nor any general formula 

could fully describe the universe of evidence that might plausibly be considered 

‘relevant to sentencing.’” Beham v. State, 559 S.W.3d 474, 479 (Tex. Crim. App. 

2018) “[T]he sentencing authority has always been free to consider a wide range of 

relevant material.” Payne v. Tennessee, 501 U.S. 808, 820-21 (1991) (citation 

omitted). The statute expressly grants the trial court discretion to allow evidence it 

“deems relevant[.]” Tex. Code Crim Proc. Ann. art. 37.07 § 3(a)(1). Therefore, we 

review a trial court’s relevancy determination under on an abuse-of discretion 

standard. McGee v. State, 233 S.W.3d 315, 318 (Tex. Crim. App. 2007). “A trial 

court abuses its discretion when it acts outside the zone of reasonable disagreement.”

The trial court received evidence, without objection, that Green was a peace 

officer and that one of the shots fired by Mahon struck him in the head, just above 

his left eyebrow. Such were the “the circumstances of the offense[.]” Tex. Code 

Crim Proc. Ann. art. 37.07 § 3(a)(1). The trial court may have reasonably inferred 

from these circumstances that a peace officer could have been killed as a result of 
15

Mahon’s conduct. Considering the trial court’s broad discretion to deem a wide 

range of evidence to be relevant in the normative process of sentencing, we cannot 

say the trial court’s exercise of decision was outside the “zone of reasonable 

disagreement.” McGee, 233 S.W.3d at 318.

We conclude that the trial court did not abuse its discretion by considering 

Green’s occupation and injuries during Mahon’ssentencing. We overruleMahon’s

second issue.

Issues Three and Four

In his third and fourth issues, Mahon argues that his sentence of twenty years

for Aggravated Assault with a Deadly Weapon constituted cruel and unusual 

punishment and is grossly disproportionate to the offense in violation of the U.S. and 

Texas constitutions. See U.S. CONST. amend. VIII; Tex. Const. art. I, § 13.

Ordinarily, to preserve an error for appellate review, the complaining party 

must present a timely and specific objection to the trial court and obtain a ruling. 

Tex. R. App. P. 33.1(a). Generally, the failure to specifically object to an alleged 

disproportionate or cruel and unusual sentence in the trial court or in a post-trial 

motion waives any error for purposes of appellate review. See Rhoades v. State, 934 

S.W.2d 113, 120 (Tex. Crim. App. 1996); Noland v. State, 264 S.W.3d 144, 151 

(Tex. App.—Houston [1st Dist.] 2007, pet. ref’d). The record reflects and Mahon 

concedes on appeal that he did not object to his sentence at the time it was 
16

pronounced or in a post-trial motion. We therefore conclude that Mahonwaived any 

complaint that his sentence was unconstitutionally disproportionate or unreasonable 

for purposes of appellate review. See Tex. R. App. P. 33.1(a). That said, even if 

Mahon had properly preserved his complaints for our review, after reviewing the 

record we conclude that his argument that his sentence is disproportionate and 

unreasonable under the Eighth Amendment of the United States Constitution and 

Article I, section 13 of the Texas Constitution lacks merit.

Generally, a sentence that is within the range of punishment established by 

the Legislature is not excessive, cruel, or unusual, and will not be disturbed on 

appeal. State v. Simpson, 488 S.W.3d 318, 323 (Tex. Crim. App. 2016); Jackson v. 

State, 680 S.W.2d 809, 814 (Tex. Crim. App. 1984). Rarely will an appellate court 

consider a punishment range for the offense excessive, unconstitutionally cruel, or 

unusual under either Texas law or the United States Constitution. See Kirk v. State, 

949 S.W.2d 769, 772 (Tex. App.—Dallas 1997, pet. ref’d); see also Jackson v. State, 

989 S.W.2d 842, 846 (Tex. App.—Texarkana 1999, no pet.). An exception to this 

general rule is recognized when the sentence is grossly disproportionate to the 

offense. Solem v. Helm, 463 U.S. 277, 289-90 (1983). Except for cases involving 

capital punishment, successful challenges to the proportionality of particular 

sentences are exceedingly rare. Id.
17

In determining whether a sentence is grossly disproportionate to a particular 

defendant’s crime, we consider (1) the severity of the sentence considering the harm 

caused to the victim; (2) the defendant’s culpability; and (3) the defendant’s prior 

adjudicated and unadjudicated offenses. Simpson, 488 S.W.3d at 323. In the rare 

case in which this threshold comparison leads to an inference of gross 

disproportionality, we then compare the defendant’s sentence with the sentences of 

other offenders in Texas and with the sentences imposed for the same crime in other 

jurisdictions. Id. “If this comparative analysis validates an initial judgment that the 

sentence is grossly disproportionate, the sentence is cruel and unusual.” Id.

As Mahon challenges only the twenty-yearsentence for aggravated assault 

with a deadly weapon on appeal, we address only that crime in our review. 

Aggravated assault with a deadly weapon is a second-degree felony, which carries a 

punishment range of confinement in the Institutional Division for a term of not more 

than twenty years or less than two years. Tex. Penal Code Ann. §§ 22.02(b), 12.33. 

In addition to imprisonment, a second-degree felony may also be punished by a fine 

not to exceed $10,000. Id. § 12.33(b). As discussed above, the trial judge assessed 

Mahon’s punishment at twenty years’ incarceration and did not impose a fine. The 

trial court heard testimony that the officers were responding to a family violence call 

at Mahon’s property, and that it was rural and dark, with very little artificial light. 

As the officers approached Mahon’s property, Mahon is observed in a “ready”

position with his gun, and fires indiscriminately into the night at the officers,

continuing to shoot after Green retreats to a ditch and returns fire. 

Having reviewed the entire record, we cannot conclude that this is one of those 

rare cases that leads to the inference that the sentence imposed was cruel and unusual 

or grossly disproportionate to the offense. See Solem, 463 U.S. at 289-90; Simpson, 

488 S.W.3d at 323; see also Kirk, 949 S.W.2d at 772. Accordingly, we overrule 

issues three and four.

Issues Five and Six

In issues five and six, Mahon argues that his constitutional right against 

double jeopardy was violated when he was charged and convicted on aggravated 

assault with a deadly weapon and two counts of deadly conduct discharge of a 

firearm. See U.S. CONST. amend. V; Tex. Const. art. I, § 14. He challenges his 

convictions for deadly conduct discharge of a firearm against Bowen and Jones

arguing that the charges arose out of a single criminal transaction and was based on 

“proof of the same facts” as his aggravated assault with a deadly weapon charge, and 

that “although [the State] used different language to describe the prohibited conduct, 

the offenses are functionally equivalent.” Mahon did not allege double jeopardy in 

the trial court and acknowledges on appeal that he did not object to double jeopardy 

either pretrial, during his plea, or subsequent punishment hearing. In Gonzalez v. 

State, the Texas Court of Criminal Appeals held that double jeopardy claims could 
19

be forfeited by procedural default—simply by failing to make an objection at trial. 

8 S.W.3d 640, 643 (Tex. Crim. App. 2000). But there is an exception which allows 

a double jeopardy claim to be raised for the first time on appeal when two conditions 

are met: (1) the undisputed facts show a double jeopardy violation is apparent on the 

face of the record; and (2) enforcement of the usual rules of procedural default serves 

no legitimate state interest.2 Id. Here, we cannot say that a double jeopardy claim is 

apparent from the face of the record. The exception thus does not apply, and Mahon 

forfeited by procedural default his double jeopardy claim.

That said, even if Mahon had preserved his double jeopardy claim, “[f]or 

offenses to be the ‘same’ for double-jeopardy purposes, they must be the same both 

in ‘law’ and in ‘fact.’”Aekins v. State, 447 S.W.3d 270, 283 (Tex. Crim. App. 2014) 

(Keller, P.J., concurring) (citing Ex parte Hawkins, 6 S.W.3d 554, 557 n.8 (Tex. 

Crim. App. 1999)). Under the Blockburger same-elements test, we look to see 

whether each offense contains an element not contained in the other; if not, they are 

the same offense and double jeopardy bars additional punishment and successive 

prosecution. United States v. Dixon, 509 U.S. 688, 696 (1993) (citing Blockburger 

v. United States, 284 U.S. 299, 304 (1932)). When those offenses are proscribed by 

2The Texas Court of Criminal Appeals has also indicated that a double 

jeopardy claim may also be cognizable on post-conviction habeas review so long as 

the same two conditions are met. Gonzalez v. State, 8 S.W.3d 640, 643 (Tex. Crim. 

App. 2000).
20

a single statute or are otherwise the same under an “elements” analysis, the 

protection against double jeopardy is not violated if the offenses constitute separate 

allowable units of prosecution. Ex parte Benson, 459 S.W.3d 67, 73 (Tex. Crim. 

App. 2015). “A ‘units’ analysis consists of two parts: (1) what the allowable unit of 

prosecution is, and (2) how many units have been shown.” Id. (footnote omitted). 

“The allowable unit of prosecution of an offense turns on statutory construction and 

usually requires ascertaining the gravamen, or gravamina, of the offense.” Ex parte 

Castillo, 469 S.W.3d 165, 169 (Tex. Crim. App. 2015). Even when those offenses 

are defined by the same penal section, the protection against double jeopardy is not 

violated if the offenses are distinguished from one another by discrete acts that are 

separate violations of the same penal section and constitute separate units of 

prosecution. Benson, 459 S.W.3d at 73.

Aggravated assault with a deadly weapon is a crime of assault. State v. 

Schunior, 506 S.W.3d 29, 38 (Tex. Crim. App. 2016) (“The offense of aggravated 

assault, Sec. 22.02, is comprised of two elements-‘assault as defined in Sec. 22.01’

and an aggravating factor[.]”); Tex. Penal Code Ann. § 22.02(a)(2). “The allowable 

unit of prosecution for an assaultive offense in Texas is each victim.” Shelby v. State, 

448 S.W.3d 431, 439 (Tex. Crim. App. 2014); see also Phillips v. State, 787 S.W.3d 

391, 395 (Tex. Crim. App. 1990). Thus, in an assault crime each victim constitutes 

a separate offense for which he may be prosecuted and convicted. See Lang v. State, 
21

183 S.W.3d 680, 685 (Tex. Crim. App. 2006). For deadly conduct with a firearm, its 

unit of prosecution is measured by the discharge of the firearm and not the number 

of victims. Miles v. State, 259 S.W.3d 240, 248–49 (Tex. App.–Texarkana 2008, pet. 

ref’d); Lozano v. State, 577 S.W.3d 275, 278 (Tex. App.—Houston [14th Dist.] 

2019, no pet.); Tex. Penal Code Ann. § 22.05(b)(1).

In this case, Mahon’s indictments allege the following:

Cause Number 21-03-03821-CR: Thomas James Mahon on or about 

March 18, 2021, and before the presentment of this indictment, in the 

County and State aforesaid, did then and there knowingly discharge a 

firearm at or in the direction of an individual, namely, [Chris Smith];

Cause Number 21-03-03822-CR: Thomas James Mahon, on or about 

March 18, 2021, and before the presentment of this indictment, in the 

County and State aforesaid, did then and there intentionally, knowingly, 

or recklessly cause bodily injury to [Jack Green], by SHOOTING THE 

COMPLAINANT, and during the commission of said assault, the 

defendant did then and there use or exhibit a deadly weapon, to-wit: A 

FIREARM; [and]

Cause Number 21-03-03823-CR: Thomas James Mahon on or about 

March 18, 2021, and before the presentment of this indictment, in the 

County and State aforesaid, did then and there knowingly discharge a 

firearm at or in the direction of an individual, namely, [Clark Jones].

Mahon pleaded guilty to all three indictments. For aggravated assaultwith a firearm, 

Mahon was convicted for shooting Green. For the deadly conduct with a firearm, 

Mahon was convicted for discharging a firearm at Smith and Jones. Each indictment 

tracks an allowable unit of prosecution for each crime. See Lang, 183 S.W.3d at 685;

Miles, 259 S.W.3d at 248–49. While not apparent from the indictment, evidence at
22

Mahon’s sentencing hearing and in the pre-sentencing reportshowsthat Mahon fired 

multiple shots that evening at the officers approaching his property, some shots 

hitting Green, followed by other shots at or in the direction oftwo other officers.We

find no double jeopardy violation even though the crimes occurred in the same 

criminal transaction. We conclude that Mahon did not face multiple punishments for 

a single offense and there was no violation of the double jeopardy clause. We 

overrule Mahon’s fifth and sixth issues.

Having overruled all of Mahon’s issues on appeal, we affirm the trial court’s 

judgments.

AFFIRMED.
