MEMORANDUM OPINION * BY
v. Record No. 2435-09-4 JUDGE ROSSIE D. ALSTON, JR.
NOVEMBER 9, 2010
COMMONWEALTH OF VIRGINIA
FROM THE CIRCUIT COURT OF LOUDOUN COUNTY
Burke F. McCahill, Judge
Joe S. Ritenour (Ritenour Paice & Mougin-Boal, on brief), for
appellant.
Joshua M. Didlake, Assistant Attorney General (Kenneth T.
Cuccinelli II, Attorney General, on brief), for appellee.
Joshua Kenneth Shortt (appellant) appeals from his conviction for driving while under the
influence of drugs in violation of Code § 18.2-266. On appeal, he argues that the trial court erred
when it held: 1) the Commonwealth proved beyond a reasonable doubt that he had the requisite
mens rea to justify conviction under Code § 18.2-266; 2) the Commonwealth’s evidence failed to
exclude every reasonable hypothesis of appellant’s innocence; and 3) appellant failed to establish
the affirmative defense of involuntary intoxication. The primary issue in this appeal is whether
appellant met his burden to present evidence sufficient to establish the affirmative defense of
“unconsciousness” predicated upon a claim of “sleep-driving.” Because we find appellant failed
to meet his burden to establish this defense, and because the evidence established only voluntary
intoxication, we find the evidence was otherwise sufficient to sustain his conviction.
Accordingly, we affirm appellant’s conviction.

Pursuant to Code § 17.1-413, this opinion is not designated for publication.
I. BACKGROUND 1
On appeal, we review the evidence in the “light most favorable” to the Commonwealth.
Commonwealth v. Hudson, 265 Va. 505, 514, 578 S.E.2d 781, 786 (2003). Therefore, we must
“‘discard the evidence of the accused in conflict with that of the Commonwealth, and regard as true
all the credible evidence favorable to the Commonwealth and all fair inferences to be drawn
therefrom.’” Parks v. Commonwealth, 221 Va. 492, 498, 270 S.E.2d 755, 759 (1980) (quoting
Wright v. Commonwealth, 196 Va. 132, 137, 82 S.E.2d 603, 606 (1954)) (emphasis omitted). So
viewed, the evidence was as follows.
On October 7, 2008, at 12:30 p.m., appellant was involved in an automobile accident in
Loudoun County. Appellant was driving east on a four-lane divided highway when his vehicle
collided with another vehicle also moving eastbound. The other driver, George Ryan, pulled his
vehicle over to the “breakdown lane” and came to a stop. After Ryan pulled over, appellant’s
vehicle again collided with Ryan’s vehicle.
Jenny Young, who was a passenger in a car driving on the same highway at the time,
witnessed appellant’s driving immediately before the accident with Ryan. Prior to appellant’s
vehicle’s collision with Ryan’s vehicle, appellant’s vehicle nearly collided with the vehicle in
which Young was a passenger. Appellant’s vehicle had accelerated quickly behind Young’s
vehicle, which was in the right lane, and the driver of Young’s vehicle avoided a collision by
accelerating in an evasive maneuver. Appellant then pulled into the left hand lane to pass
Young’s vehicle. Young observed that appellant was driving erratically by repeatedly speeding
up and slowing down, switching lanes, and braking hard. She also saw that appellant’s

passenger side mirror was broken off and hanging down as he drove. Finally, Young noticed
that appellant seemed to be talking on his cell phone as he drove, and when he got out of his car
after hitting Ryan’s vehicle, appellant put on a pair of sunglasses.
Bryan Graham, another driver on the highway around the time of appellant’s collision
with Ryan, testified at appellant’s trial that appellant got extremely close to his vehicle before
going around his car. He characterized appellant as a “crazy driver” who repeatedly ran off the
road for four to five seconds before coming back on.
After appellant collided with Ryan’s car, both vehicles stopped in the “breakdown lane.”
Young observed appellant get out of his car and described him as unsteady and wobbly. Ryan
attempted to communicate with appellant, but could not fully understand what appellant was
saying. Ryan also asked appellant a question and received no response.
Officer Susan Patterson of the Purcellville Police Department arrived on the scene shortly
after the accident and testified at trial regarding appellant’s demeanor. She indicated that
appellant was acting strangely, his pupils were dilated, and he was unsteady on his feet and
confused. She also testified that the accident was only “a couple miles” from where appellant
lived.
Deputy James Kenna of the Loudoun County Sheriff’s Office also responded to the scene
of the accident and testified at appellant’s trial. He indicated that appellant was unsteady on his
feet and obviously swaying. In addition, appellant’s motions and responses were slow and
sluggish. When Deputy Kenna spoke to appellant, he noticed that appellant had slurred speech
and bloodshot eyes. Appellant was unable to pass or even complete some of the field sobriety
tests that Deputy Kenna directed him to perform.
During Deputy Kenna’s investigation of the incident, appellant told Deputy Kenna he had
gotten off work that morning and taken some medication before going to bed. Appellant told
-3-
Deputy Kenna he had “just gotten up at 1745 hours,” was coming from home and going to work,
and he thought it was between 7:00 p.m. and 7:30 p.m. At the time of the accident, it was
actually approximately 1:00 p.m. Appellant was not wearing a work uniform; he wore sweat
pants and slipper-type shoes. Deputy Kenna indicated that appellant, when asked why he was
dressed that way, acted confused and was unable to explain his clothes. Deputy Kenna located
the sleep aid Ambien in appellant’s vehicle. He testified that the medication was prescribed to
appellant and that the Ambien pills were 10 milligrams each. He did not indicate whether there
were any warnings on the Ambien medication container or label.
A few hours after the collision, appellant’s blood was drawn for analysis. Tests found
concentrations of 0.14 per liter of blood of Zolpidem (Ambien) and 0.14 per liter of blood
Diphenhydramine (Benadryl). There was no presence of alcohol or any drugs other than the
Zolpidem and Diphenhydramine in appellant’s blood test.
Dr. Carol O’Neal, an employee of the Virginia Division of Forensic Science, testified at
appellant’s trial as an expert witness in forensic toxicology and pharmacology. She stated that a
reading of 0.14 is within the normal range for a therapeutic dose of a 10-milligram Ambien
tablet. According to Dr. O’Neal, Ambien’s main use is for the treatment of insomnia, and it
causes sedation and drowsiness and induces sleep. According to Dr. O’Neal, the drug also
causes a loss of balance and coordination, increased reaction time, confusion, disorientation, loss
of short-term memory, and slurred speech. Dr. O’Neal also testified that Benadryl has the side
effects of sedation, drowsiness, loss of balance, and loss of coordination, which could exacerbate
the effects of Ambien.
Furthermore, Dr. O’Neal testified that pharmaceutical medication literature included
warnings against “bizarre behavior or sleep-related behavior that may occur” while a person
takes Ambien, including sleep-walking and “sleep-driving.” She referenced the American
-4-
Journal of Medicine’s recognition of an inability to perform DUI field sobriety tests as another
side-effect of Ambien. Further referencing clinical studies of approximately 3,600 subjects,
Dr. O’Neal testified that sleep-walking was listed as a rare occurrence, which was observed in
less than one out of a thousand subjects. Finally, she stated that sleep-driving has been
recognized as a very rare but actual side effect of the use of Ambien.
Appellant’s mother, Leyla Dingess, also testified at the trial. She said she spoke to
appellant by telephone on the morning of October 7, 2008, and “everything was fine.” However,
she stated that when she spoke with her son at approximately 12:15 p.m. that day, he told her he
was getting ready to go to work and “there were Mexicans in his house.” Dingess became
concerned by appellant’s strange behavior. When she told appellant that it was not yet time for
him to go to work, he acted as if she had not spoken. Dingess testified that appellant was taking
Ambien, which had been prescribed to him, and that he had not had any prior incidents such as
occurred that day.
In consideration of the evidence presented, the trial court acting as fact-finder rejected
appellant’s hypothesis of innocence – that he was sleep-driving – and found him guilty of the
offense of driving under the influence of drugs in violation of Code § 18.2-266. The trial court
held that appellant was not sleep-driving and thus was not unconscious. Furthermore, the trial
court held that voluntary intoxication was not a valid defense and the facts were insufficient to
show involuntary intoxication. This appeal followed.

I. ANALYSIS
Appellant presents three issues on appeal. 2 Because appellant’s assignments of error are
interrelated and predicated on a claim that he was involuntarily intoxicated, we will consider
them under the same analysis. 3
Appellant argues that the Commonwealth failed to satisfy the mens rea requirement of
Code § 18.2-266. Appellant acknowledges that he voluntarily ingested Ambien; however, he
argues that he was involuntarily intoxicated. His argument emphasizes that appellant did not
foresee that taking the prescribed dosage of Ambien would render him unconscious and cause
him to be so intoxicated that he would “sleep-drive.” Appellant argues that the Commonwealth
failed to prove that appellant intended to produce the level of intoxication that resulted, i.e.,
sleep-driving, at the time he took the Ambien, and thus failed to prove that he had sufficient
mens rea to sustain a conviction under Code § 18.2-266. Furthermore, appellant argues that
2
As of July 1, 2010, Rule 5A:12(c)(1) was revised to require a petition for appeal to list
“Assignments of Error” instead of “Questions Presented.” Although appellant’s petition for
appeal was filed before July 1, 2010, appellant stated both “assignments of error” and “questions
presented.” Thus, we will refer to the issues raised by appellant as “assignments of error.” The
three assignments of error by appellant are:
I. The Court erred in ruling that the Commonwealth proved the
guilt of the Defendant beyond a reasonable doubt, and specifically
that the Commonwealth proved that the Defendant possessed the
requisite mens rea to justify a conviction of the offense of Driving
Under the Influence of Drugs.
II. The Court erred in ruling that the Commonwealth’s evidence
excluded each and every reasonable hypothesis consistent with the
innocence of the Defendant and was consistent only with his guilt.
III. The Court erred in ruling that the Defendant failed to establish
the affirmative defense of involuntary unconsciousness to the
offense charged.
3
Although appellant’s first assignment of error is phrased as a question of the sufficiency
of the evidence in support of his conviction, his argument on brief focuses on the trial court’s
rejection of his affirmative defense of involuntary intoxication. As such, we approach this
assignment of error from this perspective.
-6-
because he was unaware of the side-effect of sleep-driving and this side-effect was not
foreseeable, he was involuntarily intoxicated and lacked sufficient mens rea under the statute.
Involuntary intoxication is an affirmative defense. See Riley v. Commonwealth, 277 Va.
467, 479, 675 S.E.2d 168, 175 (2009). When asserting an affirmative defense, “the burden is on
the defendant to present evidence establishing such defense to the satisfaction of the fact finder,”
id. (citing Shifflett v. Commonwealth, 221 Va. 760, 769, 274 S.E.2d 305, 310 (1981)), or by “a
preponderance of evidence,” White v. Commonwealth, 46 Va. App. 123, 129, 616 S.E.2d 49, 52
(2005). Because appellant’s involuntary intoxication defense was predicated on his assertion
that he was sleep-driving, the burden was on appellant in this case to present evidence sufficient
to establish sleep-driving to the satisfaction of the trial court or by a preponderance of evidence. 4
The analysis in Riley is instructive in the instant case. In Riley, the defendant ingested,
before driving, three or four Ambien pills (for which he did not have a prescription), Benadryl,
and a pain reliever. 277 Va. at 474, 675 S.E.2d at 172. Thereafter he struck the victim and hit
two other vehicles. Id. at 474, 675 S.E.2d at 171-72. The defendant relied on an affirmative
defense of unconsciousness, predicated on sleep-driving or sleep-walking. The trial court
rejected this theory of defense. Id. at 477-78, 675 S.E.2d at 174. On appeal, the Supreme Court
of Virginia found that the trial court did not make a factual finding that the defendant was
sleep-walking at the time of the offense. Id. at 481, 675 S.E.2d at 176. Because the defendant’s
unconsciousness defense was entirely predicated upon the claim he was sleep-walking, the
4
The Supreme Court in Riley did not definitively hold that unconsciousness as a result of
sleep-walking is a viable affirmative defense under Virginia law. Riley, 277 Va. at 479-80, 675
S.E.2d at 175 (stating that “unconsciousness” is an affirmative defense, and thus the defendant
“had the burden to present evidence, to the satisfaction of the circuit court sitting as the fact
finder, that he was sleepwalking at the time he committed the charged offenses”). For the
purposes of this opinion, we assume without deciding that sleep-driving is a viable affirmative
defense.
-7-
Supreme Court held that defendant did not meet his burden of presenting sufficient evidence in
support of this defense. Id. at 481, 675 S.E.2d at 176.
Similarly to Riley, the issues raised on appeal by appellant in this case are predicated on
the affirmative defense of involuntary intoxication predicated upon sleep-driving. Thus,
appellant bore the burden of proving at trial that he was, in fact, sleep-driving. The trial court in
this case rejected appellant’s theory of defense, finding as a matter of fact that appellant was not
unconscious or sleep-driving. It stated, “I find insufficient facts to prove involuntary
intoxication, to prove unconsciousness, sleep-walking or sleep-driving.” Appellant argues that
the evidence presented by the Commonwealth was insufficient for the trial court to conclude that
he was not sleep-driving or unconscious. Accordingly, appellant suggests that he was
involuntarily intoxicated or lacked sufficient mens rea. However, this argument inverts the
applicable analysis and mischaracterizes the burden of proof on this issue. Because involuntary
intoxication is an affirmative defense, it was appellant’s burden to prove by a preponderance of
the evidence to the satisfaction of the fact-finder that he was sleep-driving. It was not the
Commonwealth’s burden to prove that appellant was not sleep-driving. See Riley, 277 Va. at
479, 675 S.E.2d at 175; Shifflett, 221 Va. at 769, 274 S.E.2d at 310; White, 46 Va. App. at 129,
616 S.E.2d at 52.
Whether or not an affirmative defense has been established is “usually a question for the
trier-of-fact.” Reed v. Commonwealth, 6 Va. App. 65, 70, 366 S.E.2d 274, 277 (1988) (holding
that “claim of right is an affirmative defense and thus usually a question for the trier-of-fact”).
“The trier of fact determines the weight of evidence” in support of a claim of an affirmative
defense. Gardner v. Commonwealth, 3 Va. App. 418, 426, 350 S.E.2d 229, 233 (1986) (holding
that the trier of fact “determines the weight of evidence in support of a claim of self-defense”).
Furthermore, on appeal, findings of fact made by the trial judge are presumed to be correct and
-8-
are “given the same effect as a jury verdict, settling all conflicts in the evidence in favor of the
prevailing party.” Richmond v. Beltway Properties, 217 Va. 376, 379, 228 S.E.2d 569, 572
(1976) (citing Reiber v. Duncan, 206 Va. 657, 660, 145 S.E.2d 157, 160 (1965)). The trial
court’s findings of fact are given deference, “unless the findings are ‘plainly wrong or without
evidence to support them.’” Carter v. Commonwealth, 42 Va. App. 681, 686, 594 S.E.2d 284,
287 (2004) (citing Timbers v. Commonwealth, 28 Va. App. 187, 193, 503 S.E.2d 233, 235-36
(1998)).
In this case, the trial court reviewed both the Commonwealth’s and appellant’s evidence
and concluded that as a matter of fact appellant was not sleep-driving. Thus, the trial court
concluded that appellant failed to establish the affirmative defense of involuntary intoxication.
Based on the evidence adduced at trial, we cannot say that the trial court’s finding that appellant
was not sleep-driving was plainly wrong or without evidence to support it. Appellant drove
around two vehicles, those in which Young and Graham were riding, prior to hitting Ryan’s
vehicle. He also successfully pulled over and stopped his car after striking Ryan’s vehicle.
Appellant put sunglasses on when he was outside his vehicle on a sunny day and used a cell
phone while in his car roadside. Finally, appellant was able to communicate with the
investigating officer and, albeit unsuccessfully, attempted to perform field sobriety tests. These
facts support the trial court’s factual finding that appellant was in fact conscious as he drove.
Because appellant’s involuntary intoxication argument is predicated on a finding that appellant
was sleep-driving, in light of this evidence, appellant failed to carry his burden to establish
involuntary intoxication.
As a corollary to his arguments regarding mens rea and involuntary intoxication,
appellant argues that the evidence did not exclude the reasonable hypothesis that he was
unconscious and sleep-driving at the time of the accident.
-9-
“‘Whether an alternative hypothesis of innocence is reasonable is a question of fact and,
therefore, is binding on appeal unless plainly wrong.’” Emerson v. Commonwealth, 43 Va. App.
263, 277, 597 S.E.2d 242, 249 (2004) (quoting Archer v. Commonwealth, 26 Va. App. 1, 12-13,
492 S.E.2d 826, 832 (1997)). Where the fact-finder has rejected the hypothesis of innocence,
“the trial court’s judgment must be affirmed unless it is plainly wrong or without evidence to
support it.” Sheppard v. Commonwealth, 250 Va. 379, 387, 464 S.E.2d 131, 136 (1995).
In this case, the trial court rejected appellant’s alternative hypothesis of innocence,
finding as a matter of fact that appellant was not sleep-driving. For the reasons stated above, we
cannot conclude that this finding was plainly wrong or without evidence to support it. Thus,
appellant’s argument fails.
III. CONCLUSION
Appellant’s mens rea argument, involuntary intoxication defense, and hypothesis of
innocence argument are all predicated on his claim that appellant was unconscious. Because the
trial court’s finding that appellant was not in fact sleep-driving was not plainly wrong or without
evidence to support it, the trial court did not err in rejecting appellant’s arguments. For the
foregoing reasons, we affirm appellant’s conviction.
Affirmed.
