WILLIAM LEE SMARR, Appellant

V.

THE STATE OF TEXAS, Appellee

 

On Appeal from the 115th Judicial District Court

Upshur County, Texas

Trial Court No. 15,237

 

Before Morriss, C.J., Carter and Moseley, JJ.

Memorandum Opinion by Chief Justice Morriss

MEMORANDUM OPINION

No doubt, William Lee Smarr had ingested a mix of legal prescription medications1before 

he attempted to drive his three children home after a day-long fishing trip, ultimately resulting in a 

jury deciding that Smarr was guilty of DWI, with child passengers, and assessing a sentence of 

fifteen months’ confinement. The trial court sentenced Smarr consistent with the jury’s 

assessment. The questions before us on Smarr’s appeal concern the sufficiency of the evidence to 

prove that Smarr drove without his normal mental or physical faculties because he had ingested 

medications. Because we determine that the evidence was legally and factually sufficient, we 

affirm the judgment of the trial court.

As the Smarr vehicle approached Smarr’s house, its erratic movements suggested Smarr’s 

distress. First, the vehicle stopped in the middle of the road with its motor running. Then, with 

Smarr apparently unconscious or semiconscious, the vehicle began moving forward. When 

Smarr did not respond to his children’s calls, and the vehicle passed Smarr’s driveway, one 

quick-thinking son got down on the floorboard and held Smarr’s foot on the brake pedal while the 

other quick-thinking son steered the vehicle off the road. 

By the time the police arrived, Candace Smarr, the children’s mother and Smarr’s ex-wife, 

had taken the children to their residence located ―right back up the road‖ and had returned to the 

scene. Ms. Smarr told the police that Smarr had taken too much medication. Smarr was 

 

1The medications had been prescribed to treat Smarr’s pain caused by ―a herniated disc in his neck and low back,‖ as 

well as a crush injury to his foot. 
3

transported to a local hospital in an ambulance and was diagnosed as suffering from an overdose of 

prescription medication. Approximately nine days later, Smarr was diagnosed as suffering from 

mild hypoglycemia (low blood sugar).

On appeal, Smarr argues the evidence is legally and factually insufficient to support the 

jury’s verdict. The State was required to prove that Smarr did not have ―normal use of mental or 

physical faculties by reason of the introduction of . . . a drug . . . into the body.‖ See TEX. PENAL 

CODE ANN. §§ 49.01, 49.04 (Vernon 2003), § 49.045 (Vernon Supp. 2009). Smarr’s argument is 

limited to whether he was intoxicated by reason of the introduction of a drug. Smarr points out 

that the police and medical personnel at the hospital never bothered to look for any cause of 

Smarr’s impairment other than the one suggested by Smarr’s recently divorced wife—an overdose 

of medication. According to Smarr, his conviction is the result of this myopia. Smarr posits that 

the evidence establishes reasonable doubt that his condition was caused by the introduction of a 

drug into his body, rather than the result of hypoglycemia compounded by dehydration.

In conducting a legal sufficiency review, we consider 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. Laster v. State, 275 S.W.3d 512, 517 

(Tex. Crim. App. 2009). We must give deference to ―the responsibility of the trier of fact to fairly 

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

facts to ultimate facts.‖ Hooper v. State, 214 S.W.3d 9, 13 (Tex. Crim. App. 2007) (citing 
4

Jackson v. Virginia, 443 U.S. 307, 318–19 (1979)). 

In conducting a factual sufficiency review, we consider the evidence in a neutral light. 

Watson v. State, 204 S.W.3d 404, 414–15 (Tex. Crim. App. 2006). We may find evidence 

factually insufficient in two ways: (1) the evidence supporting the conviction is ―too weak‖ to 

support the fact-finder’s verdict, or (2) considering conflicting evidence, the fact-finder’s verdict 

is against the great weight and preponderance of the evidence. Laster, 275 S.W.3d at 518. Both 

legal and factual sufficiency are measured by the elements of the offense as defined by a 

hypothetically correct jury charge. Malik v. State, 953 S.W.2d 234, 240 (Tex. Crim. App. 1997); 

see also Grotti v. State, 273 S.W.3d 273, 280 (Tex. Crim. App. 2008).

David Cruze, a deputy with the Upshur County Sheriff’s Office, testified that, at the scene, 

Smarr had ―difficulty maintaining his balance‖:

As I asked him to walk back to my car, he was stumbling, he had to grab onto the 

side of the truck to keep his - - to keep his balance, and as we got to the back of the 

truck, past the back of his vehicle, I was walking to his right, he just fell to the left 

and started stumbling real hard to the [l]eft and I had to actually grab him by his 

arm to keep him from falling down, which he would have.

Smarr informed Cruze he had not had anything to drink, but had taken his medication. Cruze did 

not smell any odor of alcohol on Smarr and did not find any alcohol in the vehicle. 

Wes Whalen, a paramedic for the East Texas Medical Center, testified that, at the scene, 

Smarr’s speech was slurred and he appeared to be intoxicated. Whalen testified that Smarr told 

him he had ingested a morphine tablet and that Smarr’s vehicle contained prescription bottles of 
5

Alprazolam (Xanax), Soma, and Norco. Smarr had been prescribed a sustained-release form of 

morphine referred to in the record as MS-Contin. Whalen testified he performed a test for blood 

sugar, referred to as a D-stick, at the scene, but did not know the results. Whalen testified that a 

saline solution was administered to Smarr intravenously. 

At the hospital, Smarr was examined by Dr. Brian Kempton, an emergency physician. 

When Kempton first examined Smarr, Smarr had slurred speech, responded slowly to questions, 

and appeared lethargic. Kempton testified that Smarr seemed not to understand he was lethargic 

and concluded Smarr’s ―insight into what was going on seemed impaired.‖ The hospital took a 

sample of Smarr’s blood approximately thirty-three minutes after Kempton’s first visit. Kempton

testified that Smarr’s blood did not contain detectable levels of alcohol. Smarr’s blood tested 

positive for opiates and benzodiazepine, but the quantity of those substances was not determined. 

Smarr denied taking an overdose of his medication. Two of Smarr’s prescribed drugs, 

MS-Contin, which is a sustained-release form of morphine, and Norco, which is a form of 

hydrocodone, would ―show up positive as opiates‖ in a blood test. The Xanax prescribed to 

Smarr is a benzodiazepine. When asked if a person could be intoxicated on a mixture of ―Soma, 

Norco, Xanax, morphine, even if they were within therapeutic levels,‖ Dr. Kempton responded, 

―I’d say there’s a significant interaction among those that would -- I think anybody who took that 

would be intoxicated.‖ When asked if anything in his report would lead him to believe Smarr was 

in hypoglycemic shock, Kempton responded, ―Nothing here . . . Normal people don’t get 
6

hypoglycemic. I mean, that just is vanishingly rare.‖ Kempton testified his notes do not indicate 

a result for the D-stick test for Smarr’s blood-sugar level, but also testified EMS personnel 

normally check a patient’s blood-sugar level. Kempton diagnosed Smarr as suffering from a drug 

overdose and testified it was ―pretty obvious that [Smarr] was heavily intoxicated on multiple 

substances.‖ Kempton testified that he treated Smarr for only forty minutes and that his 

interaction with Smarr was pretty limited. 

Just minutes after the blood sample was drawn, there was a shift change at the hospital. 

Dr. David Buller, a physician who has a family practice and also works as an ER physician at the 

hospital, came on duty. By a coincidence, Buller was Smarr’s family physician. At the hospital, 

Buller diagnosed Smarr as suffering from a drug overdose. Buller did not order any additional 

testing at the hospital, and Smarr was discharged from the hospital approximately forty-four 

minutes after Buller came on duty. Buller, though, was surprised at Smarr’s quick recovery and 

testified he ―would not expect a drug overdose to cure that rapidly.‖2 Buller testified Smarr had 

been a patient of his for more than five years and was taking the medications before becoming his 

patient. Buller testified that, if the medications had been taken as prescribed, Smarr would have 

been safe to drive a motor vehicle. Approximately nine days after Smarr’s hospital visit, Buller 

conducted a glucose tolerance test on Smarr and diagnosed Smarr with mild hypoglycemia.3 The 

 

2Kempton agreed MS-Contin would ―wear off slowly.‖ 

3The State argues that glucose tolerance test performed by Buller ―showed Smarr’s glucose levels to be within the 

normal range‖ and, therefore, ―does not even contradict the jury’s verdict.‖ The State’s argument suggests that 
7

results of the glucose tolerance test caused Buller to revise his diagnosis and to conclude that 

Smarr’s condition was the result of multiple factors including hypoglycemia, dehydration,4and 

the medications. Buller testified, ―[T]here are -- I believe are multiple factors involved, 

hypoglycemia could be a possibility, drinking Monster drinks which he admitted to could be a 

contributing factor in addition to taking his regular dose of medication.‖ Buller admitted that 

Smarr’s blood test at the hospital indicated a glucose level of 97, a normal level. Buller testified 

that Smarr’s body could have corrected the blood-sugar level in the hour between the arrest and the 

blood test through ―a process of glucogensis‖ where ―the body would recognize the sugar is low‖ 

and ―would take protein and fat and convert it back into sugar, raise the blood sugar back up to a 

level that the body likes.‖5 The State cross-examined Buller:

Q. . . . in an hour and 41 minutes you’re telling me it’s normal for you to raise 

your glucose level that high?

A. That’s not what I said.

Q. It’s not normal, is it?

 

Buller’s diagnosis is incorrect and, therefore, does not contradict the jury’s verdict. We have no doubt that the 

diagnosis of hypoglycemia is more complicated than merely comparing the test results to the ranges preprinted on the 

test result form. Buller admitted the glucose levels were within the ranges which might be considered normal, but 

testified the variances in the blood-sugar levels led him to conclude Smarr was hypoglycemic. We are not medical 

doctors, and it is not our role to determine whether Buller’s diagnosis was correct. The State did not present any 

expert testimony that Buller’s analysis of the glucose tolerance test was incorrect.

4Buller testified that Smarr reported fishing all day without eating, but while drinking Monster drinks on ―a pretty 

warm day.‖ Buller opined that, therefore, Smarr was probably ―a little dehydrated as well.‖ 

5Kempton testified that a person who was suffering from hypoglycemic shock would recover only if ―we intervened 

some way,‖ such as giving him ―glucose or even an IV of glucose.‖ Kempton testified that the chart did not indicate 

any fluids were administered to Smarr. However, as noted above, Whalen testified that a saline solution was

administered intravenously.
8

A. That’s not what I said.

Q. Okay. Is that normal?

A. Unlikely.

Q. Unlikely.

A. Uh-huh, to go that big a distance. That’s why my opinion is more than one 

thing involved.

When asked, ―Can you say with any medical probability that he was in the condition he was due to 

a drug overdose on that day,‖ Buller responded, ―I cannot.‖ 

The State limits its appellate argument to whether the evidence is sufficient to show that 

Smarr took an overdose of his prescription medication. The State, though, was not required to 

prove Smarr took an overdose. The fact that a defendant was entitled to use prescribed 

medication is not a defense to DWI. See TEX. PENAL CODE ANN. § 49.10 (Vernon Supp. 2009). 

―[A] person may drive after taking a prescription medication so long as that person has not lost the 

normal use of his mental or physical faculties by reason of introduction of the prescription drug 

into his body.‖ Paschall v. State, 285 S.W.3d 166, 178 (Tex. App.—Fort Worth 2009, pet. ref’d). 

Thus, our review is not concerned with whether the evidence supports a conclusion that Smarr 

took more medication than prescribed. The question, rather, is whether the evidence supports a 

conclusion that Smarr’s impaired condition resulted from ingesting prescription drugs, regardless 
9

of the amount.6

A rational person could have concluded that, beyond a reasonable doubt, Smarr was guilty. 

The jury could have chosen to believe Kempton’s diagnosis over the diagnosis of Buller. 

Kempton testified the prescription drugs could have caused Smarr to be intoxicated even if taken at 

therapeutic levels and, in his opinion, Smarr’s condition was the result of Smarr’s prescription 

drugs. The jury could have rejected Buller’s testimony. The evidence is legally sufficient.

The next question is whether the evidence is factually sufficient to support the jury’s 

verdict. Buller testified Smarr’s hypoglycemia and dehydration may have contributed to Smarr’s 

condition. We note that ―a defendant cannot be found to be intoxicated if he lacks the normal use 

of mental or physical faculties for a different reason, such as disability, illness, fatigue, stress, or 

clumsiness.‖ Hernandez v. State, 107 S.W.3d 41, 51 (Tex. App.—San Antonio 2003, pet. ref’d); 

see Drapkin v. State, 781 S.W.2d 710, 711 (Tex. App.—Texarkana 1989, pet. ref’d) (―Fatigue is 

not an affirmative defense. It is an alternative cause.‖); Massie v. State, 744 S.W.2d 314, 316 

(Tex. App.—Dallas 1988, pet. ref’d); cf. Atkins v. State, 990 S.W.2d 763, 767 (Tex. App.—Austin 

1999, pet. ref’d) (error to give instruction on synergistic effect of fatigue and alcohol).

In a factual sufficiency review, however, we may find the evidence insufficient only when 

necessary to prevent manifest injustice. Laster, 275 S.W.3d at 518. Although we give less 

 

6We are not suggesting the amount of drugs in Smarr’s body is not relevant to the inquiry of whether Smarr’s condition 

was caused by the prescription drugs. Buller testified a quantitative test could have been conducted. A quantitative 

analysis would have greatly strengthened the State’s case. However, the State did not perform any tests to determine 

the quantity of the prescribed medication in Smarr’s blood. While such a quantitative analysis would have 

strengthened the State’s case, such an analysis is not required. 
10

deference to the verdict in a factual sufficiency review, we will not override the verdict simply 

because we disagree with it. Id. Buller testified merely that Smarr’s hypoglycemia was a factor 

in causing the condition. According to Buller, the condition was caused by multiple factors, 

including hypoglycemia, dehydration, and the prescribed medications, acting together. Thus, 

Buller’s testimony does not establish that hypoglycemia and dehydration caused Smarr’s 

impairment by themselves, or conversely that the drugs did not cause it. Even according to 

Buller, the prescribed medication still played a role in Smarr’s condition. The overwhelming 

great weight and preponderance of the evidence does not dictate a finding against Smarr’s drug 

ingestion causing his impairment. Nor is the evidence of medication-caused impairment so weak 

that the State failed to establish Smarr’s guilt beyond a reasonable doubt. Our skepticism about 

the jury’s conclusion is not sufficient to reach the high level required to reverse a jury’s verdict. 

The evidence is factually sufficient.

For the reasons stated, we affirm the trial court’s judgment.
