STATE OF NORTH CAROLINA
v.
JOHN AKBAR VENABLE, Defendant.
Appeal by Defendant from judgment entered 9 August 2023 by Judge G. Bryan
Collins in Wake County Superior Court. Heard in the Court of Appeals 8 April 2025.
Attorney General Jeff Jackson, by Special Deputy Attorney General Kathryne E. Hathcock, for the State.
Stephen G. Driggers for Defendant.
GRIFFIN, Judge.
Defendant John Akbar Venable appeals from the trial court’s judgment
entered after a jury found him guilty of felony death by vehicle and driving while
impaired. Defendant raises four issues on appeal. Defendant contends the trial court
erred by (1) denying his Motion to Dismiss for insufficient evidence; (2) admitting
expert testimony of retrograde extrapolation; and (3) declining to give the entire civil
pattern jury instruction on intervening negligence. Defendant also argues he
received ineffective assistance of counsel. We hold the trial court did not err, and
Defendant did not receive ineffective assistance of counsel.
I. Factual and Procedural Background STATE V. VENABLE
Opinion of the Court
This case arises from a car crash resulting in the death of Lee Venable in
Raleigh, North Carolina. The evidence presented at trial tended to show as follows:
Around 7:26 p.m. on 2 August 2021, Defendant crashed his car into a tree at
Old Wake Forest Road and Forest Oaks Drive in Raleigh. Defendant’s wife, Mrs.
Venable, was in the passenger seat of the vehicle. Seth Wood witnessed Defendant
drive off Old Wake Forest Road in his red Kia Rio. Defendant crashed into a tree
seconds later. Mr. Wood immediately called 911 and went to assist Defendant and
Mrs. Venable. Defendant’s vehicle was severely damaged and both airbags were
deployed. Defendant exited the vehicle to check on Mrs. Venable. Mr. Wood observed
Defendant’s balance was poor, his speech was difficult to understand, and he
appeared disoriented. Defendant walked a short distance away from the car and lay
down on the grass while several residents of nearby houses tended to Mrs. Venable.
Mr. Wood found Mrs. Venable’s oxygen tank behind the passenger seat and attached
it to her nose.
Mary Gerow, a registered trauma nurse, was one of the people to help. Ms.
Gerow found Mrs. Venable unconscious and potentially not breathing. Ms. Gerow
performed CPR on Mrs. Venable until EMS arrived. During this time, Ms. Gerow
observed an odor of alcohol on Defendant.
Officer Jenks responded to the scene shortly after the crash. Mr. Wood
explained to Officer Jenks what he had witnessed leading up to the crash and
indicated Defendant had been driving. Ms. Gerow told Officer Jenks Defendant
-2- STATE V. VENABLE
smelled like alcohol. Officer Jenks and Officer Daniel Egan searched Defendant’s
vehicle and found five empty airplane bottles of E&J brandy. Local ABC store
surveillance video footage later revealed Defendant purchased eight airplane bottles
of E&J brandy and one airplane bottle of Fireball whiskey just after 5:00 p.m. on the
day of the crash. Also, inside Defendant’s vehicle, officers found Food Lion grocery
bags and three Food Lion receipts, two of which were time stamped around an hour
prior to the crash. One of the grocery bags contained raw chicken breast.
Paramedic Mark Underhill of Wake County EMS responded to the scene and
treated Defendant for chest pain. He found Defendant alert and aware of the
situation he was in. Defendant admitted he drank “a few beers” and claimed his wife
had “grabbed [his] face,” causing him to crash. Defendant and Mrs. Venable were
transported to Wake Med Hospital for treatment. Mrs. Venable died at the hospital
from blunt force trauma as a result of her injuries in the crash.
At the hospital, Defendant told Officer Egan he had consumed E&J brandy and
Fireball whiskey. Defendant stated he drank one of the airplane bottles around forty-
five minutes prior to driving. Officer Egan later contacted the witnesses present at
the scene. Ms. Gerow stated she “smelled a strong odor of alcohol on [Defendant],”
and Mr. Wood stated Defendant was “generally incoherent.” After investigating the
incident, and through his own observations, Officer Egan believed Defendant was
appreciably impaired at the time of the crash due to alcohol consumption.
While at the hospital, a blood sample was collected from Defendant for medical
-3- STATE V. VENABLE
purposes at 8:37 p.m. The blood test reflected an alcohol concentration of 0.0883
grams of alcohol per 100 milliliters of blood. Later that evening, Defendant consented
to a chemical analysis blood test, and at 10:43 p.m., a second blood sample was
collected from Defendant. The test revealed an estimated alcohol concentration of
0.05 grams of alcohol per 100 milliliters of blood.
Dr. Richard Waggoner, a forensic chemist for the Raleigh-Wake County
Bureau of Identification, performed a retrograde extrapolation analysis to determine
Defendant’s blood alcohol concentration at the time of the accident. Dr. Waggoner
extrapolated Defendant’s blood alcohol concentration was 0.1078 grams of alcohol per
100 milliliters of blood at the time of the crash.
On 29 November 2021, Defendant was indicted for felony death by vehicle and
driving while impaired. Defendant’s case came on for trial on 7 August 2023 in Wake
County Superior Court.
At trial, Defendant requested the jury receive a civil intervening negligence
instruction. A portion of the instruction was given to the jury. On 9 August 2023,
the jury found Defendant guilty of both driving while impaired and felony death by
motor vehicle. Defendant timely appeals.
II. Analysis
Defendant contends the trial court erred by (1) denying his Motion to Dismiss
for insufficient evidence; (2) admitting expert testimony of retrograde extrapolation;
and (3) declining to give the entire civil pattern jury instruction on intervening
-4- STATE V. VENABLE
negligence. Defendant also argues he received ineffective assistance of counsel.
A. Motion to Dismiss
Defendant argues the trial court erred by denying his Motion to Dismiss for
insufficient evidence. Specifically, Defendant contends Officer Egan’s opinion that
Defendant was “appreciably impaired” at the time of the crash was unsupported by
the evidence. We disagree.
We review the denial of a motion to dismiss for insufficient evidence de novo.
State v. Tucker, 380 N.C. 234, 236, 867 S.E.2d 924, 927 (2022) (citation and internal
marks omitted)). “In reviewing challenges to the sufficiency of evidence, we must
view the evidence in the light most favorable to the State, giving the State the benefit
of all reasonable inferences. Contradictions and discrepancies do not warrant
dismissal of the case but are for the jury to resolve.” Id. at 237, 867 S.E.2d at 927. If
there is substantial evidence to support each element of the charged crime, the trial
court properly denied the motion to dismiss. Id. at 236, 867 S.E.2d at 927.
Substantial evidence is more than a scintilla of evidence. Id. at 237, 867 S.E.2d at
927.
To be found guilty of driving while impaired, “the State must prove beyond a
reasonable doubt” the defendant drove a vehicle “upon a public vehicular area” (1)
while appreciably impaired “or (2) after having consumed sufficient alcohol that he
has, at any relevant time after the driving, an alcohol concentration of 0.08 or more.”
State v. Narron, 193 N.C. App. 76, 79 666 S.E.2d 860, 863 (2008) (citation and internal
-5- STATE V. VENABLE
marks omitted) (emphasis added); N.C Gen. Stat. § 20-138.1(a) (2023). Notably, these
are two “separate, independent, and distinct ways” to be convicted of driving while
impaired. State v. Watson, 286 N.C. App. 143, 149, 879 S.E.2d 355, 360 (2022). Thus,
the jury may convict a person of driving while impaired based on appreciable
impairment “without proof of the person’s blood alcohol concentration.” Id. Or “[t]he
jury may independently convict a person of driving while impaired for driving with
an alcohol concentration of 0.08 or more if the State proves that the person’s blood
alcohol concentration was 0.08 or more.” Id. Here, there was sufficient evidence to
convict Defendant under either prong.
1. Appreciable Impairment
A person is appreciably impaired when their impairment can be “recognized
and estimated.” State v. Harrington, 78 N.C. App. 39, 45, 336 S.E.2d 852, 855 (1985).
“[I]t is a well-settled rule that a lay person may give his opinion as to whether
a person is intoxicated so long as that opinion is based on the witness’s personal
observation.” State v. Rich, 351 N.C. 386, 398, 527 S.E.2d 299, 306 (2000) (citation
omitted). This Court has held that “[a]n officer’s opinion that a defendant is
appreciably impaired is competent testimony and admissible evidence when it is
based on the officer’s personal observation of an odor of alcohol and of faulty driving
or other evidence of impairment.” State v. Gregory, 154 N.C. App. 718, 721, 572 S.E.2d
838, 840 (2002) (emphasis added).
Here, Officer Egan did not personally observe an odor of alcohol on Defendant,
-6- STATE V. VENABLE
but he did observe “other evidence of impairment.” Id. See Rich, 351 N.C. at 399,
527 S.E.2d 299 at 306 (holding an officer’s opinion sufficient where it was not solely
based on the “odor of alcohol, but also on his investigation of the accident and upon
his experience enforcing traffic laws and dealing with intoxicated drivers”).
Here, Officer Egan personally observed the collision scene, the roadway marks
and Defendant’s vehicle found in the trees; found five empty E&J brandy bottles
inside Defendant’s vehicle; and spoke with Defendant at the hospital. Defendant
admitted to Officer Egan he had been drinking before driving. Thus, we hold Officer
Egan’s personal observations constitute “other evidence of impairment” sufficient to
support his opinion testimony.
Moreover, the State’s evidence was not limited to Officer Egan’s opinion. The
State presented ample evidence to support Defendant’s impairment at the time of the
crash. See Rich, 351 N.C. at 398–99, 527 S.E.2d at 306 (holding evidence sufficient
to support impairment where an officer “observed the collision scene[,] observed [the]
defendant at the hospital, [] two witnesses testified that they saw [the] defendant’s
car going seventy mph around a curve just before the collision[,] and other witnesses
testified as to [the] defendant’s odor of alcohol”); State v. Hewitt, 263 N.C. 759, 764,
140 S.E.2d 241, 244 (1965) (“The fact that a motorist has been drinking, when
considered in connection with faulty driving such as following an irregular course on
the highway or other conduct indicating an impairment of physical or mental
faculties, is sufficient prima facie to show a violation of [section] 20-138.[1(a)].”
-7- STATE V. VENABLE
(citation omitted)).
Here, in addition to Officer Egan’s testimony, the jury heard Mr. Wood testify
Defendant’s balance was poor, his speech was difficult to understand, and he
appeared disoriented. Ms. Gerow stated Defendant smelled like alcohol, and Officer
Jenks explained what he observed and collected at the scene. Thus, we hold there
was sufficient evidence presented to the jury to support Defendant being appreciably
impaired at the time of the crash.
2. Alcohol Concentration
In addition to the evidence presented to support Defendant’s appreciable
impairment, the State presented evidence of Defendant’s alcohol concentration at the
time of the crash. “The results of a chemical analysis are sufficient to prove a person’s
blood alcohol concentration.” Watson, 286 N.C. App. at 150, 879 S.E.2d at 361 (citing
N.C. Gen. Stat. § 20-138.1(a)(2)).
Dr. Waggoner extrapolated Defendant’s blood alcohol concentration was
0.1078 grams of alcohol per 100 milliliters of blood at the time of the crash. Dr.
Waggoner based his analysis on Defendant’s blood drawn at the hospital at 8:37 p.m.
and 10:43 p.m., Defendant’s own statements, and the evidence found at the scene.
The crash occurred at 7:26 p.m., and Defendant’s blood sample taken at 8:37 p.m.,
just over an hour after the crash, revealed an alcohol concentration of 0.0883 grams
per 100 milliliters of blood. See State v. Patterson, 209 N.C. App. 708, 714, 708 S.E.2d
133, 137 (2011) (holding it was not error to admit a blood sample taken three hours
-8- STATE V. VENABLE
after the defendant’s arrest). Thus, Defendant’s blood alcohol concentration was
sufficient in and of itself to convict Defendant of driving while impaired. N.C. Gen.
Stat. § 20-138.1(a)(2).
Accordingly, we hold there was sufficient evidence presented to support
Defendant’s DWI conviction on grounds of appreciable impairment and blood alcohol
concentration. As a result, the trial court did not err by denying Defendant's Motion
to Dismiss.
B. Retrograde Extrapolation
Defendant alleges the trial court plainly erred by admitting expert testimony
of retrograde extrapolation. Specifically, Defendant contends Dr. Waggoner’s
testimony regarding Defendant’s blood alcohol concentration at the time of the crash
was unreliable because he made “critical assumptions” unsupported by the record.
We disagree.
For this Court to hold a trial court plainly erred, the defendant must satisfy a
three-factor test. State v. Reber, 386 N.C. 153, 158, 900 S.E.2d 781, 786 (2024). First,
the defendant must demonstrate a “fundamental error occurred at trial.” Id. (citing
State v. Lawrence, 365 N.C. 506, 518, 723 S.E.2d 326, 334 (2012)). Second, “that the
error had a ‘probable impact’ on the outcome, meaning that ‘absent the error, the jury
probably would have returned a different verdict.’” Id. (quoting Lawrence, 365 N.C.
at 518–19, 723 S.E.2d at 334). Third, “that the error is an ‘exceptional case’ that
warrants plain error review . . . showing that the error seriously affects ‘the fairness,
-9- STATE V. VENABLE
integrity or public reputation of judicial proceedings.’” Id. (quoting Lawrence, 365
N.C. at 518, 723 S.E.2d at 334).
Rule 702(a) of the North Carolina Rules of Evidence “‘incorporates the
standard from the Daubert line of cases’ in federal evidentiary jurisprudence.” State
v. Babich, 252 N.C. App. 165, 167, 797 S.E.2d 359, 361-62 (2017) (quoting State v.
McGrady, 368 N.C. 880, 888, 787 S.E.2d 1, 8 (2016)). Rule 702(a) permits an expert
witness to testify in the form of an opinion if: “(1) [t]he testimony is based upon
sufficient facts or data[;] (2) [t]he testimony is the product of reliable principles and
methods[;] and (3) [t]he witness has applied the principles and methods reliably to
the facts of the case.” N.C. R. Evid. 702(a) (1–3) (2023).
When the reliability of expert testimony is challenged on appeal, we cannot
consider “data or theories . . . which were neither before the trial court when the
expert opinion was admitted nor made part of the record on appeal.” State v. Gray,
259 N.C. App. 351, 351–52, 815 S.E.2d 736, 738 (2018).
On appeal, Defendant does not dispute that retrograde extrapolation is a
widely acceptable method of proving blood alcohol content. See State v. Cook, 362
N.C. 285, 293, 661 S.E.2d 874, 879 (2008) (“North Carolina courts have consistently
regarded blood alcohol retrograde extrapolation as the domain of expert witnesses.”);
State v. Davis, 142 N.C. App. 81, 90, 542 S.E.2d 236, 241 (2001) (“We have accepted
the reliability of extrapolation evidence since 1985.” (citation omitted)). Rather,
Defendant contends Dr. Waggoner’s opinion that Defendant was in a post-absorptive
- 10 - STATE V. VENABLE
state with a blood alcohol concentration of 0.1078 at the time of the crash was
unreliable because his analysis “was not properly tied to the facts of the particular
case.” Defendant contends Dr. Waggoner assumed, based on information
unsupported by the record, Defendant was drinking on an empty stomach, and that
the crash occurred fifty-one minutes after his last drink.
When an expert performs a retrograde extrapolation analysis, the subject
needs to be in a “post-absorptive or post-peak state–meaning that alcohol is no longer
entering the subject’s bloodstream and thus [his] blood alcohol level is declining.”
Babich, 252 N.C. App. at 168, 797 S.E.2d at 362. Factors, “such as when the person
last consumed alcohol (and how much was consumed), and whether the person
consumed any food that could delay the alcohol’s absorption into the bloodstream”
can impact whether a person is in a post-absorptive state. Id. at 169, 797 S.E.2d at
362.
This Court has held “when an expert witness offers a retrograde extrapolation
opinion based on an assumption that the defendant is in a post-absorptive or post-
peak state, that assumption must be based on at least some underlying facts[.]” Id.
at 172, 797 S.E.2d at 364. “This might come from the defendant’s own statements
during the initial stop, from the arresting officer’s observations, from other witnesses,
or from circumstantial evidence that offers a plausible timeline for the defendant’s
consumption of alcohol.” Id. “When there are at least some facts that can support
the expert’s assumption that the defendant is post-peak or post-absorptive, the issue
- 11 - STATE V. VENABLE
then becomes one of weight and credibility, which is the proper subject for cross-
examination or competing expert witness testimony.” Id. The weight and credibility
of the expert testimony is for the jury to decide. State v. Dew, 225 N.C. App. 750, 760,
738 S.E.2d 215, 222 (2013) (citation omitted).
Defendant relies on State v. Babich, a case where this Court held the trial court
abused its discretion by admitting retrograde extrapolation testimony because “the
opinion of the State’s expert was not sufficiently tied to the particular facts of [the]
case[.]” Babich, 252 N.C. App. at 167, 797 S.E.2d at 361. There, the expert “conceded
[] she had no factual information in [the] case from which she could assume that [the]
[defendant] was in a post-absorptive state.” Id. at 169, 797 S.E.2d at 362. She
admitted she had not been provided with any facts or data “whatsoever” “about when
[the defendant’s] last consumption of alcohol was, or whether [the] [defendant]
consumed food . . . prior[.]” Id.
Here, unlike in Babich, Dr. Waggoner considered several facts in making his
calculations and in determining whether Defendant was in a post-absorptive state at
the time of the crash. Dr. Waggoner explained he based his analysis on the blood
drawn at the hospital at 8:37 p.m. and 10:43 p.m., Defendant’s own statements, and
the evidence found at the scene. Defendant purchased nine airplane bottles of alcohol
just after 5:00 p.m. Defendant admitted he drank three airplane bottles, but seven
were found empty. Defendant also admitted he drank an airplane bottle forty-five
minutes before driving. Defendant left Food Lion at 6:35 p.m., and the crash occurred
- 12 - STATE V. VENABLE
at 7:26 p.m. Defendant did not eat or drink anything after the crash, and there was
no evidence that he had eaten any of the groceries in the car prior to the crash.
Defendant’s blood sample, taken at 8:37 p.m., just over an hour after the crash,
revealed an alcohol concentration of 0.0883 grams of alcohol per 100 milliliters of
blood. Defendant’s second blood sample, taken at 10:43 p.m., revealed an alcohol
concentration of 0.05 grams of alcohol per 100 milliliters of blood.
Thus, because Dr. Waggoner based his opinion on underlying facts and
explained to the jury what those underlying facts were, we hold the trial court did not
err by admitting Dr. Waggoner’s opinion testimony.
Moreover, even if it was error to admit Dr. Waggoner’s testimony, it does not
amount to plain error. Defendant has not shown a reasonable probability that had
the alleged error not occurred, a different result would have been reached at trial.
Reber, 386 N.C. at 158, 900 S.E.2d at 786. See Babich, 252 N.C. App. at 173, 797
S.E.2d at 365 (holding retrograde extrapolation testimony error but not prejudicial
error because there was ample evidence presented to support the defendant’s
impairment outside of the challenged testimony); State v. Taylor, 165 N.C. App. 750,
758, 600 S.E.2d 483, 489 (2004) (holding “even if the admission of [the] [expert’s]
testimony was error, the error was not prejudicial” because of the evidence presented
to support the defendant’s appreciable impairment under the first prong of section
20-138.1). See also State v. Sigmon, 74 N.C. App. 479, 482, 328 S.E.2d 843, 846 (1985)
(rejecting the defendant’s contention that an alcohol concentration of 0.06 must create
- 13 - STATE V. VENABLE
a presumption that the defendant is not impaired; “substantial evidence, separate
and apart from [a] breathalyzer result” can support a conviction on grounds of
appreciable impairment).
Here, like in Babich and in Taylor, as discussed in the section above, there was
ample evidence presented to support Defendant’s conviction on the basis of
appreciable impairment, absent any testimony of Defendant’s blood alcohol
concentration at the time of the crash. Thus, we hold the trial court did not plainly
err by admitting the testimony.
C. Intervening Negligence Jury Instruction
Defendant argues the trial court plainly erred by failing to give the entire jury
instruction on intervening negligence and did not include intervening negligence in
its final mandate on the charge of felony death by motor vehicle. We disagree.
“The elements of felony death by vehicle are: (1) [the] defendant
unintentionally causes the death of another; (2) while driving impaired as defined by
N.C. Gen. Stat. §§ 20-138.1 or 20-138.2 [(2023)]; and (3) the impairment was the
proximate cause of the death.” State v. Bailey, 184 N.C. App. 746, 748, 646 S.E.2d
837, 839 (2007) (citing N.C. Gen. Stat. § 20-141.4(a1)).
In State v. Bailey, a felony death by vehicle case, the jury was instructed the
defendant’s negligence need not be the sole proximate cause. Id. at 749, 646 S.E.2d
at 839. Intervening negligence is found where the negligence of another “break[s] the
causal chain of the defendant’s negligence[.]” Id. (citation and internal marks
- 14 - STATE V. VENABLE
omitted). If it does not break the causal chain, the defendant’s act is still a proximate
cause. Id. (citation omitted). Here, the trial court properly instructed the jury on
proximate cause. The instructions provided:
A proximate cause is . . . a cause without which the victim’s death would not have occurred and one that a reasonably careful and prudent person could foresee would probably produce such injury or some similar injurious result. The defendant’s act need not have been the last or nearest cause. It is sufficient if it concurred with some other cause acting at the same time which, in combination with it, proximately caused the victim’s death.
A natural and continuous sequence of causation may be interrupted or broken by the negligence of a second person. This occurs when a second person’s negligence was not reasonably foreseeable by the first person and causes its own natural and continual sequence which interrupts, breaks, displaces, or supersedes the consequences of the first person’s negligence. Under such circumstances, the negligence of the second person . . . insulates the negligence of the first person and would be the sole proximate cause of the incident.
The intervening negligence jury instruction sufficiently incorporated the
necessary principles outlined in Bailey. Additionally, the trial court’s final mandate
on felony death by vehicle included the appropriate law on proximate cause.
Moreover, even if it was error for the court not to read the entire jury
instruction, the error does not amount to plain error—the jury probably would not
have returned a different verdict—based on the evidence presented to support
Defendant’s guilt. Reber, 386 N.C. at 158, 900 S.E.2d at 786. Here, ample evidence,
including the testimony of two eyewitnesses, was presented to show Defendant drove
- 15 - STATE V. VENABLE
off the roadway into a tree while appreciably impaired and caused the single-vehicle
crash that resulted in his wife’s death.
We hold the trial court did not err in its jury instructions, but even if it did, it
does not amount to prejudicial error.
D. Ineffective Assistance of Counsel
Defendant argues he received ineffective assistance of counsel because his trial
counsel failed to object to the testimony of Officer Egan and Dr. Waggoner, and
because Defense counsel failed to object to the incomplete jury instruction. We
disagree.
To challenge a conviction based on ineffective assistance of counsel, a
defendant must establish that his counsel’s conduct “fell below an objective standard
of reasonableness.” State v. Braswell, 312 N.C. 553, 561–62, 324 S.E.2d 241, 248
(1985) (citing Strickland v. Washington, 466 U.S. 668, 688 (1984)). “[T]o meet this
burden, the defendant must satisfy a two-part test.” Id. at 562, 324 S.E.2d at 248.
First, the defendant must prove that his “counsel’s performance was deficient,” such
that “counsel made errors so serious that counsel was not functioning as the ‘counsel’
guaranteed the defendant by the Sixth Amendment.” Id. Second, the defendant must
prove his counsel’s performance was prejudicial, such that “counsel’s errors were so
serious as to deprive the defendant of a fair trial, a trial whose result is reliable.” Id.
As held above, the challenged testimony was not error, nor was the lack of
objection to the allegedly incomplete jury instruction on intervening negligence.
- 16 - STATE V. VENABLE
Thus, Defendant cannot meet the first prong of the ineffective assistance of counsel
test and Defendant’s argument fails.
III. Conclusion
We hold the trial court properly denied Defendant’s Motion to Dismiss,
properly admitted Dr. Waggoner’s retrograde extrapolation analysis, and properly
gave appropriate jury instructions on intervening negligence. Additionally, we hold
NO ERROR.
Judges ZACHARY and FLOOD concur.
