LLOYD DAVID DEMUS, Appellant 

V. 

THE STATE OF TEXAS, Appellee 

On Appeal from the 283rd Judicial District Court 

Dallas County, Texas 

Trial Court Cause No. F-23-00001-T 

MEMORANDUM OPINION 

Before Justices Partida-Kipness, Pedersen, III, and Carlyle 

Opinion by Justice Carlyle 

A jury found Lloyd David Demus guilty of manslaughter and sentenced him 

to 75 years’ imprisonment. On appeal, Demus challenges the sufficiency of the 

evidence to support his conviction and eight of the trial court’s rulings. We affirm 

the trial court’s judgment in this memorandum opinion. See TEX. R. APP. P. 47.4. 

I. The evidence was sufficient to show Demus drove the car that killed 

S.G. 

We review the evidence in the light most favorable to the verdict to determine 

whether any rational trier of fact could have found the essential elements of the crime 

beyond a reasonable doubt, giving full play to the factfinder’s responsibility to 
 –2– 

resolve conflicts in testimony, weigh evidence, and draw reasonable inferences from 

basic facts to ultimate facts. See Jackson v. Virginia, 443 U.S. 307, 319 (1979). It is 

well established that the State may prove identity by circumstantial evidence, 

coupled with all reasonable inferences from that evidence. See Earls v. State, 707 

S.W.2d 82, 85 (Tex. Crim. App. 1986). 

Demus ran a stop sign going 60 miles per hour in a residential neighborhood 

at 7am on a school day while high on PCP. He crashed into Juan Gomez’s car as 

Gomez drove his three siblings to get doughnuts before school; the crash killed his 

little brother and injured the others. Demus tried to flee on foot but was hampered 

by his ankle having been nearly severed in the crash. 

Demus contests the sufficiency of the State’s evidence by asking this court to 

ignore what that evidence established and to reweigh the evidence. He places 

particular focus on his testimony that he was asleep in the passenger seat while his 

sister, who died after the wreck but before trial, crashed into S.G.’s car and left the 

scene undetected. Demus’s testimony directly contradicts his admission in the 

hospital to police that he was driving and caused the fatal accident. He explained the 

shift in his story by suggesting that he did not want to get his sister in trouble while 

she was alive, but since she was dead, that was no longer an obstacle. 

While in the hospital, Demus asked to meet with Detective Kenneth Watson, 

and Watson recorded their conversation. Initially, Demus said his friend Jeffrey 

Bennett was the driver, but when Detective Watson told him S.G. died in the crash, 
 –3– 

Demus confessed he drove and crashed the car. The conversation continued with 

Demus demonstrating his ability to recall details before and after the wreck, 

including where the driver side airbag hit him and his desire to flee the scene despite 

suffering a compound fracture of his ankle that one witness described as “severed” 

and “barely hanging on.” 

The State presented substantial identity evidence including (1) DNA evidence 

from the driver’s side airbag, gear shift, and driver’s side window; (2) expert 

testimony that the DNA profile from the vehicle matched Demus’s DNA profile; (3) 

the most conservative statistic for matching the DNA profile from the vehicle to a 

randomly selected person “was less than one in 10 trillion”; (4) expert testimony 

connecting the spiderweb crack on the driver’s side windshield to Demus’s forehead 

injury; (5) expert testimony confirming the car’s airbag system was functional and 

concluding it didn’t deploy on the passenger side because the seat was unoccupied; 

(6) witnesses identifying Demus as the driver and sole occupant; and (7) Demus’s 

attempt and plea for help to flee the scene. 

We hold the State provided sufficient evidence from which a rational jury 

could conclude Demus was the driver and reject Demus’s first issue. 

II. The trial court did not abuse its discretion by admitting lay witness 

testimony describing Demus’s ankle injury. 

In his second and third issues, Demus contends the trial court abused its 

discretion when it permitted Dwayne Giddings to testify over his objection about the 
 –4– 

ankle injury Demus sustained in the collision because the testimony was speculative 

and because Giddings was not qualified as an expert. 

We disregard nonconstitutional errors that do not have a substantial injurious 

effect or influence on the jury’s verdict, and examine the entire record in our 

analysis. TEX. R. APP. P. 44.2(b); see Coble v. State, 330 S.W.3d 253, 280 (Tex. 

Crim. App. 2010). Only when we are fairly assured that the error did not influence 

the jury or had but a slight effect will we conclude that the error was harmless. Id.

Assuming error, admitting Giddings’s testimony about Demus’s ankle injury was 

harmless. See TEX. R. APP. P. 44.2(b). 

Giddings was startled by the booming crash and was one of the first witnesses 

to the scene in front of his house. A licensed commercial truck driver, Giddings spent 

the bulk of his testimony describing the scene, including finding Demus in the 

middle of the street with his ankle nearly severed and pulling Demus out of the street 

and onto the curb. Giddings answered two questions giving his opinion about 

Demus’s ankle injury, which he purported to base on his background as a trucker 

seeing numerous wrecks. Giddings’s testimony on this matter was not exactly clear, 

and it was clear he did not know which foot was Demus’s “driving foot,” which 

would have mattered given that he seemed to suggest he had known of vehicle 

accidents causing similar ankle injuries to a driver’s “driving foot.” In any event, 

Giddings final statement on the matter was, “That’s just experience.” 
 –5– 

Out of 260 pages of the State’s witness examinations, only slightly more than 

2 related to Giddings’s trucking experience and his opinion that Demus’s ankle 

injury indicated an injury to a driver. See Gonzalez v. State, 544 S.W.3d 363, 373 

(Tex. Crim. App. 2018) (considering the number of pages that erroneous testimony 

took up relative to the rest of the testimony). The State did not refer to Giddings’s 

testimony about the ankle injury at any other point in trial and causation of Demus’s 

ankle injury was not at issue. The extent to which Giddings’s ankle injury testimony 

put Demus behind the wheel does not rise to the level of affecting Demus’s 

substantial rights. See TEX. R. APP. P. 44.2(b). We reject Demus’s second and third 

issues. 

III. The trial court did not abuse its discretion when it overruled Demus’s 

other evidentiary objections. 

We review a trial court’s decision to admit or exclude evidence for an abuse 

of discretion. Green v. State, 934 S.W.2d 92, 101–02 (Tex. Crim. App. 1996). A trial 

court abuses its discretion when its decision falls outside the zone of reasonable 

disagreement. Henley v. State, 493 S.W.3d 77, 83 (Tex. Crim. App. 2016). Trial 

courts have broad discretion in their evidentiary rulings and are usually in the best 

position to make the call on whether to admit or exclude certain evidence. Guzman 

v. State, 955 S.W.2d 85, 89 (Tex. Crim. App. 1997). We uphold the trial court’s 

ruling if it is reasonably supported by the evidence and is correct under any theory 

of law applicable to the case. State v. Ross, 32 S.W.3d 853, 856 (Tex. Crim. App. 
 –6– 

2000). We reverse a trial court’s ruling on the admissibility of evidence only where 

the court abused its discretion and the error harms appellant. See Solomon v. State, 

49 S.W.3d 356, 365 (Tex. Crim. App. 2001); TEX. R. APP. P. 44.2(b). 

In his fourth issue, Demus argues the trial court erred when it overruled his 

objection when the State asked Detective Watson: “In your opinion, did the 

defendant recklessly cause the death of [S.G.] by operating a motor vehicle at an 

unreasonable speed for the conditions?” Demus timely objected that the State’s 

question called for speculation and for the detective to give an opinion on an ultimate 

issue. Demus has not briefed his speculation argument, see TEX. R. APP. P. 38.1(i), 

and opinions on ultimate issues are permissible. TEX. R. EVID. 704; see Ex parte 

Nailor, 149 S.W.3d 125, 134–35 (Tex. Crim. App. 2004). 

In his fifth issue, Demus argues the trial court erred when it overruled his 

objection to evidence of his non-cooperation when the State executed a warrant to 

get his buccal swab. Evidence is relevant if it has any tendency to make a fact more 

or less probable than it would be without the evidence and the fact is of consequence 

in determining the action. TEX. R. EVID. 401. Irrelevant evidence is inadmissible. 

TEX. R. EVID. 402. “Evidence does not need to prove or disprove a particular fact by 

itself to be relevant; it is sufficient if the evidence provides a small nudge toward 

proving or disproving a fact of consequence.” Anguiano v. State, No. 05-22-00680-

CR, 2024 WL 885042, at *5 (Tex. App.—Dallas Mar. 1, 2024, no pet.) (mem. op., 

not designated for publication). 
 –7– 

Haley Young, a Dallas Police Department crime scene analyst, testified that 

Demus “was not enthused about having to have a buccal swab done” and that he had 

to be restrained while it was performed. On appeal, Demus argues the danger of 

unfair prejudice outweighs the probative value of Young’s testimony. At trial, 

Demus did not object that the danger of unfair prejudice outweighed the probative 

value of Young’s testimony. The point of error on appeal must comport with the 

objection made at trial. Clark v. State, 365 S.W.3d 333, 339 (Tex. Crim. App. 2012). 

Thus, Demus has not preserved his rule 403 argument. See TEX. R. APP. P. 

33.1(a)(1). 

Demus did, however, preserve his objection to relevance. The State argues it 

was relevant because it was an act “designed to reduce the likelihood of prosecution, 

conviction, or incarceration for the offense on trial,” showing consciousness of guilt. 

See Wilson v. State, No. 04-02-00052-CR, 2003 WL 21418463, at *6 (Tex. App.—

San Antonio 2003, not pet.) (mem. op., not designated for publication) (Richardson, 

J.) (citing Ransom v. State, 920 S.W.2d 288, 299 (Tex. Crim. App. 1994)). Though 

it leans more to the “small” part of the phrase “small nudge,” the evidence that 

Demus was uncooperative during a buccal swab some two years after the incident 

could support a conclusion that Demus was trying to “reduce the likelihood of 

prosecution, conviction, or incarceration for the offense on trial.” See id.; Gonzalez, 

544 S.W.3d at 370. 
 –8– 

In his sixth issue, Demus similarly argues the trial court abused its discretion 

when it overruled his objection to Detective Watson’s testimony about the effects of 

PCP on the basis that it was repetitive, “not material,” and “has no probative value.” 

See TEX. R. EVID. 403. To the extent Demus argues on appeal that this evidence 

constitutes impermissible bolstering, he did not make this argument at trial and 

therefore did not preserve it for our review. See TEX. R. APP. P. 33.1(a)(1).1

Dr. Simonson testified that when someone is using PCP, they are easily 

agitated, difficult to restrain, and have increased resistance to pain. Dr. Simonson 

also testified that Demus admitted to using PCP that morning, that in Demus’s drug 

screen upon admission to the trauma center, his results were presumptively positive 

for PCP use, that he had blood pressure of 186 over 121, and that his heart rate was 

122 beats per minute. 

In contrast, Detective Watson testified that PCP “dissociates the brain’s ability 

to feel pain,” that someone who was using it could break their legs and still run down 

the street, that it is a dangerous drug, that officers cannot “inflict enough pain” to 

stop someone who is using it, and that he could run over someone using PCP with 

his car and that they would not feel it. Detective Watson further explained that PCP 

elevates both blood pressure and pulse, that average blood pressure is 120 to 140 

1

 In any event, a bolstering objection may not have preserved anything for our review either. See Rivas 

v. State, 275 S.W.3d 880, 886 (Tex. Crim. App. 2009); Bellard v. State, No. 05-21-00633-CR, 2023 WL 

1097769, at *6 n.4 (Tex. App.—Dallas Jan. 30, 2023, pet. ref’d) (mem. op., not designated for publication). 
 –9– 

over 70 to 90, that the average heart rate is up to 90 beats per minute, and that 

Demus’s vitals were consistent with PCP use. 

Though there was some overlap in what Detective Watson and Dr. Simonson 

testified to, Detective Watson gave more detail in several regards. As a result, there 

was no danger of needlessly cumulative evidence that could have outweighed the 

probative value of his testimony and the trial court did not abuse its discretion when 

it overruled Demus’s rule 403 objection. 

In his seventh issue, Demus argues the prosecutor impermissibly said during 

punishment arguments that S.G.’s sister, also a passenger in the vehicle, suffered a 

“head fracture.” However, the medical records admitted into evidence showed that 

S.G.’s sister suffered a parietal bone fracture. A parietal bone fracture is a head 

fracture. See STEDMAN’S MEDICAL DICTIONARY FOR THE HEALTH PROFESSIONS AND 

NURSING 1251 (7th ed. 2011) (“[P]arietal bone . . . A flat, curved bone . . . at either 

side of the vault of the cranium.”). The trial court did not err. 

IV. There was no harmful error in the trial court’s refusal to issue a 

curative instruction or to grant a mistrial after sustaining Demus’s 

outside-the-record objections to the prosecutor’s closing argument at 

punishment. 

In his eighth and ninth issues, Demus argues the trial court erred when it 

denied his requests for an oral instruction to disregard the State’s argument and for 

a mistrial. The prosecutor told the jury during closing argument that, “[E]veryone 

here has had cases – manslaughter cases that we’ve been involved with 2:00 a.m. on 
 –10– 

75[.]” Demus timely objected that the State was arguing outside the record and the 

trial court promptly sustained his objection. 

Assuming the court’s refusal to instruct the jury to disregard was error, we 

must determine whether it affects Demus’s substantial rights. 

See TEX. R. APP. P. 44.2(b). The prosecutor’s brief, incomplete, and vague 

reference to middle-of-the-night manslaughter cases on a dangerous Dallas highway 

did not, as Demus suggests but does not explain, go “right to the ultimate issue of 

the case.” At best, it is an inapt comparison to the wreck in this case, which happened 

in a residential area as children went to school. The facts of this case are far worse 

than the vague hypothetical the prosecutor offered, and we cannot find the court’s 

failure to instruct the jury to disregard it to have affected Demus’s substantial rights. 

Finally, to evaluate whether the trial court abused its discretion by denying a 

mistrial for improper jury argument, we balance (1) the magnitude of the prejudicial 

effect of the prosecutor’s remarks, (2) the efficacy of any cautionary instructions by 

the judge, and (3) the strength of the evidence supporting the punishment. See Archie 

v. State, 221 S.W.3d 695, 700 (Tex. Crim. App. 2007). As noted, the magnitude of 

the remarks was small and occurred during punishment arguments, yet the court 

declined Demus’s request to disregard. The objectionable statement did not involve 

a comment on Demus’s failure to testify or his non-testimonial behavior during trial. 

See id.; Good v. State, 723 S.W.2d 734, 738 (Tex. Crim. App. 1986) (en banc). And, 

the evidence in support of the punishment was strong, including two prior felony 
 –11– 

enhancement paragraphs and the death of a child in this crash. Though the jury 

recommended a 75-year sentence, we cannot conclude the trial court erred when it 

denied Demus’s motion for a mistrial in light of these factors. 

V. Conclusion 

Having overruled all of Demus’s issues on appeal, we affirm his conviction.
