MEMORANDUM OPINION 1
----------
Appellant Arturo Armijo was charged in trial court cause number
1224172D (02-11-00430-CR) with felony driving while intoxicated (DWI) and in
trial court cause number 1224396D (02-11-00431-CR) with possession of less
than one gram of cocaine. The felony DWI was enhanced with a habitual
offender notice. The possession of cocaine charge was enhanced from a state

See Tex. R. App. P. 47.4.
jail felony to a second-degree felony. The cases were tried jointly before a jury,
which convicted Appellant of both offenses, and, finding the enhancement
allegations to be true, assessed his punishment at thirty years’ confinement in
the felony DWI case and at five years’ confinement in the possession of cocaine
case, with the sentences to be served concurrently. The trial court sentenced
Appellant accordingly in each case.
Appellant brings a single point on appeal, complaining that the trial court
reversibly erred by admitting evidence of retrograde extrapolation in the felony
DWI case and that the error in the DWI case tainted the jury verdict in the
cocaine case, number 1224396D. Because we hold that the trial court did not
reversibly err, and because Appellant cites us to no law or argument to support
his complaint that error in the DWI case created reversible error in the cocaine
case, we affirm the trial court’s judgments.
Officer Jamie Fagan, a City of Fort Worth police officer, was working the
third shift on December 19, 2010, on East Lancaster. She observed a small
pickup approaching her that was driving the wrong way on East Lancaster.
Officer Fagan stopped the pickup. Appellant was its driver. Officer Fagan
testified that Appellant’s speech was slurred, he smelled of alcohol, and he was
unsteady on his feet. Although Appellant could speak English, Officer Fagan
summoned Officer Gilbert Lara to the scene to speak with Appellant in Spanish.
Officer Fagan testified that, inside the pickup, she saw three empty Coors beer
cans and another can of Coors beer that was approximately half-full.
2
Officer Lara performed a horizontal-gaze-nystagmus test, but Appellant
refused to participate in the one-leg stand and walk-and-turn field sobriety tests.
He explained to the officer that he could not perform those tests because of the
injuries he had received in the Vietnam War. At trial, both Officer Lara and
Officer Fagan offered the opinion that Appellant had been intoxicated at the time
of his arrest.
Appellant’s blood test, administered about four hours after his arrest,
showed his blood alcohol concentration (BAC) to be .20.
While he was being booked into the jail, Appellant was discovered to have
a small baggie of white powder in his wallet. When the powder was tested, it
was found to be .05 grams of cocaine.
At trial, Dr. Robert Johnson, chief toxicologist for the Tarrant County
Medical Examiner’s office, offered his opinions regarding Appellant’s BAC at the
time of his arrest, based on retrograde extrapolation and upon the fact that
Appellant’s BAC reading was not obtained until some four hours after his arrest.
Dr. Johnson admitted that he did not have sufficient facts upon which to base an
opinion with reasonable scientific certainty. Specifically, on voir dire, Dr. Johnson
testified to the factors that go into retrograde extrapolation. He testified as
follows:
You need the height and weight of the person that we’re
talking about. We’d like to know the time of the last drink, so we
would be able to tell if all the ethanol is absorbed, and we’d like to
know the time of the last meal, so we could get an idea if there was
3
any food in the stomach that would have delayed absorption of that
last drink.
....
If the last drink was completely absorbed, a retrograde
extrapolation can be done fairly accurately. Because elimination is a
linear function and you just add the number of hours times that
elimination rate to the original result. Without that knowledge, if the
last—or if there is unabsorbed alcohol in the stomach, it makes it
very difficult to follow that extrapolation lying down, because you
don’t know how much was in the stomach at the time of the incident.
....
If there is food in the stomach, that absorption is slowed. So it
affects—while it affects the rate of the absorption and it increases
the likelihood that there was unabsorbed alcohol in the stomach,
which makes that estimate of alcohol concentration more difficult.
....
If you’re still absorbing alcohol, you’re on that upper portion
of—you’re still increasing in alcohol concentration, so it makes
picking a time on the decreasing side of that curve more difficult[. I]t
can be impossible.
If you are purely eliminating ethanol, everything’s been
absorbed, you’re on the linear function on the backside, on the
decreasing side of the curve, it is mathematically valid to estimate an
alcohol concentration at a previous time.
....
We can—we do it three ways. We use the average and we
will present that generally. If someone is a habitual drinker, they
eliminate ethanol faster, so we can do a faster rate of elimination in
that case.
If someone’s a naive drinker, they eliminate alcohol slower, so
we can use a lower elimination rate in that case. I used the average
today.
....
4
The range is .01 on the naive drinker side to .025 on the
habitual drinker side. So it’s more than double, the rate would be
more than double for a—what we consider an alcoholic.
Dr. Johnson testified that he did not measure or weigh Appellant but was
provided a height of 5'7ʺ and a weight of 180 pounds. Dr. Johnson admitted that,
because he was missing several of the necessary factors, his estimates
concerning Appellant’s BAC at the time of his arrest could be different from the
actual BAC. He also said that the fact that the blood test was completed four
hours after the stop made it easier to get a number, because within the first hour,
all ethanol is absorbed. The remaining three hours would be on the linear
backside of the curve, so he could be fairly confident that only elimination was
taking place. But Dr. Johnson admitted that there were many unknowns.
Nevertheless, he testified before the jury that people start losing the use of
their mental or physical faculties at .03 or .04:
The drinking while in the car makes it very difficult, because
we don’t know how much was left unabsorbed in the stomach at the
time of the stop. The . . . fact that it’s four hours between the stop
and the time of the test, that helps a little bit, because all of the
ethanol that would have been consumed prior to the stop would
have been absorbed within the first hour after the stop. So that
leaves us basically from 3:00 a.m. to 6:15. So about three hours of
only elimination and no absorption of additional alcohol.
So if we added three hours worth of elimination to the .2, it
would have been about—on average, about point .24, maybe.
That’s an estimate.
Only at that point did Appellant take Dr. Johnson on voir dire and then
lodge his objections to the testimony. But the question posited to Dr. Johnson
5
when he offered that testimony was, “Are you able to come to a result based on
that set of facts?” The question called for a “yes” or “no” answer, not for his
conclusion.
Appellant contends that the trial court abused its discretion by admitting
the retrograde extrapolation evidence. The State asks us to hold that Appellant
did not preserve this issue for appellate review. Appellant concedes that Dr.
Johnson had testified before the jury concerning his credentials and had begun
to offer opinions regarding Appellant’s BAC at the time of his arrest. Because the
BAC test was not completed until approximately four hours after Appellant’s
arrest, Dr. Johnson’s testimony necessarily involved retrograde extrapolation.
Appellant requested a hearing outside the presence of the jury, and after the
hearing, Appellant contended that Dr. Johnson did not have sufficient facts upon
which to base an opinion with reasonable scientific certainty. Dr. Johnson
conceded that critical factors that he himself had described as necessary for an
accurate retrograde extrapolation conclusion were not known. Appellant
objected to Dr. Johnson’s testimony regarding Appellant’s probable BAC at the
time of his arrest, but the trial court disagreed with Appellant’s position and
permitted Dr. Johnson to testify to the probable BAC before the jury. We hold
that Appellant sufficiently preserved his complaint by objecting to the testimony
regarding retrograde extrapolation and receiving an unfavorable ruling.
After Appellant’s objection was overruled, the State reminded Dr. Johnson
that he had testified that “the person who was driving that car’s [BAC] can be as
6
high as .024 . . . .” Dr. Johnson responded that that was a rough estimate but
that he felt pretty confident that the BAC would be higher than .2.
The Texas Court of Criminal Appeals has held that evidence of retrograde
extrapolation is not admissible unless significant underlying facts are present
rendering the opinion evidence reliable. 2 But the erroneous admission of such
evidence does not typically constitute constitutional error. 3 Consequently, under
rule of appellate procedure 44.2(b), the erroneous admission of such evidence is
not reversible if it had no more than a slight effect on the jury’s verdict. 4
The Texas Court of Criminal Appeals explained in Bagheri v. State that in
determining whether there was harm from nonconstitutional error,
[t]he question is not whether there was sufficient evidence to support
the verdict. Instead, the reviewing court should consider the entire
record when making this determination, including testimony, physical
evidence, jury instructions, the State’s theories and any defensive
theories, closing arguments, and voir dire if applicable. Important
factors are “the nature of the evidence supporting the verdict, the
character of the alleged error and how it might be considered in
connection with other evidence in the case.” More specifically, the
reviewing court should consider whether the State emphasized the
error, whether the erroneously admitted evidence was cumulative,
and whether it was elicited from an expert. 5

Taking Dr. Johnson at his word that he did not have enough information to
perform retrograde extrapolation that was sufficiently reliable to determine
accurately Appellant’s BAC at the time of his arrest, we examine the record to
determine whether erroneous admission of the retrograde extrapolation
testimony substantially affected Appellant’s rights so that it had more than a
slight effect on the jury’s verdict. 6 The felony DWI indictment alleged merely that
Appellant operated a motor vehicle in a public place while intoxicated, without
stating the manner or means of intoxication. The State was free, then, to prove
either per se intoxication or lack of normal use. 7 The police found beer
containers in Appellant’s pickup. His BAC reflected in the blood draw was .20.
The police saw him driving in the wrong direction against oncoming traffic.
Specifically, Officer Fagan testified that she first saw Appellant’s pickup
while she was driving eastbound on Lancaster in Fort Worth. She saw
headlights coming toward her in the same lane. She testified that there were
three eastbound lanes and three westbound lanes. The eastbound lanes and
westbound lanes were separated by a large median with trees. She was
concerned about the safety of the public because the pickup was traveling on the
wrong side of the median, which meant that it was traveling westbound in the
lanes on the eastbound side of the median. After she stopped Appellant, she

spoke with him and realized that his speech was slurred and that he appeared
intoxicated. The officers smelled the odor of alcoholic beverage and testified that
Appellant’s eyes were bloodshot and watery. They also observed that Appellant
was swaying and that his balance was unsteady after he got out of the truck.
The evidence of intoxication, if believed, was overwhelming, even without
evidence of retrograde extrapolation.
The officers also found a baggie of cocaine in Appellant’s pocket.
We therefore hold that the erroneous admission of the retrograde
extrapolation testimony did not affect Appellant’s substantial rights to a fair trial or
substantially affect or in any way undermine confidence in the jury’s verdict in the
felony DWI case and was therefore harmless. We further hold that the improper
admission of the retrograde extrapolation testimony likewise had no effect on the
cocaine case, and therefore likewise caused no harm in that case.
We, therefore, overrule Appellant’s sole point and affirm the trial court’s
judgments.
