GREER, Judge.
Did a second test for controlled substances and drugs on blood drawn
pursuant to a warrant, initially tested just for blood alcohol content (BAC), violate
Neil Wenzel’s constitutional rights under the Fourth Amendment and article I,
section 8? Prefacing this as an important case of first impression, Wenzel appeals
from the denial of his motion to suppress the results of a chemical analysis for
controlled substances and drugs, as well as his subsequent conviction of operating
while intoxicated (OWI), second offense, in violation of Iowa Code section
321J.2(1) and (2)(b) (2020).1 To narrow the focus, he contends that while the initial
stop, blood draw, and test for alcohol were proper, a second test for controlled
substances and drugs was not. Drilling down further, Wenzel argues the separate
test for controlled substances was not supported by probable cause, thus it
violated both his federal Fourth Amendment and state article I, section 8
constitutional rights. The State asserts that probable cause existed but, even so,
individuals lose their expectation of privacy to the intoxicants in their blood after it
has been lawfully removed, and so the chemical analysis is not a distinct search
for our constitutional analysis. And, the State contends seizing blood under a valid
1 Iowa Code section 321J.2(1) provides:
A person commits the offense of operating while intoxicated if
the person operates a motor vehicle in this state in any of the
following conditions:
a. While under the influence of an alcoholic beverage or other
drug or a combination of such substances.
b. While having an alcohol concentration of .08 or more.
c. While any amount of a controlled substance is present in
the person, as measured in the person’s blood or urine.
It has been said that the purpose of chapter 321J is “to reduce the
holocaust on our highways.” State v. Kelly, 430 N.W.2d 427, 429 (Iowa 1988)
(citation omitted).

search warrant to test for intoxication, followed by testing for drugs, is reasonable.
We do not address head on Wenzel’s argument that the chemical analysis is part
of a constitutional search; instead, we hold the blood test for controlled substances
was both authorized by the warrant and the testing did not exceed the scope
authorized by the issuing judge as supported by probable cause, and so we affirm
Wenzel’s conviction and sentence.
I. Background Facts and Proceedings.
No one contests the facts. In May 2020, Wenzel was pulled over by Deputy
Shawn Syverson after failing to yield to an emergency vehicle. When Deputy
Syverson spoke to Wenzel, he noticed Wenzel’s watery and bloodshot eyes, his
slurred speech, and the smell of alcohol. Wenzel admitted he had a beer earlier
in the day. With those observations and Wenzel’s admission, Deputy Syverson
asked Wenzel to complete field sobriety tests; Wenzel refused. After Deputy
Syverson requested Wenzel submit to a breath test, Wenzel again refused. Rather
than invoking implied consent, Deputy Syverson applied for a search warrant to
draw and test Wenzel’s blood. To obtain the warrant, Deputy Syverson filled out
several pages of the warrant application. He specifically requested a blood
specimen after confirming on the form that there was probable cause to believe a
traffic violation under Iowa Code section 321J.2 occurred. In the first attachment
to the application, the provided language on the form stated the need for testing
was to aid the investigation and determine what role the use of alcoholic
beverages, controlled substances, or drugs played in the traffic offense.
Next, Deputy Syverson completed a second attachment—“A-2
OBSERVATIONS OF IMPAIRMENT”—and on this form the application provided
4
boxes to check for observations of different indicators of impairment. Here, it was
noted that Wenzel refused all field sobriety tests. Deputy Syverson checked
several items that were “observations of Suspect establishing probable cause that
Suspect is under the influence of an alcoholic beverage, and/or controlled
substance and/or drug.” He checked boxes for bloodshot eyes, watery eyes,
slurred speech, smell of alcohol coming from the suspect, judgment impaired, and
poor driving behavior.
5
Below that section, there was also a group of boxes to check under the heading
“controlled substances” that allowed disclosure of controlled substances or drug
paraphernalia found. The final box referenced “Reasonable grounds to believe the
Suspect is under the influence of a controlled substance or drug based on the
following observations,” followed by space for a narrative. While Deputy Syverson
marked behavioral indicators for impairment that applied to Wenzel at the top of
the form, he did not write a narrative or check any of the boxes in the controlled-
substances section.
As a final part of the warrant application, Deputy Syverson attached a
written narrative describing the stop. That narrative read:
Wenzel failed to yield to my police vehicle when I had
emergency lights activated as I was attempting to turn around on the
highway. Wenzel was the lone occupant and driver of the vehicle.
Wenzel had bloodshot and glassy eyes and slurred speech while I
was speaking to him. I had the suspect step out of the vehicle and
sit with me in my patrol car where I could smell an odor of alcoholic
beverages coming from his person. I requested Wenzel perform the
Standardized Field Sobriety Tests but he refused. I asked him if he
would take a preliminary breath test and he refused.
With this written documentation before it, the issuing court granted the
search warrant to take a blood sample to determine if Wenzel violated section
321J.2(1) by operating while under the influence of alcoholic beverages, controlled
substances, or drugs. Meanwhile, Wenzel was arrested and charged with OWI,
second offense. Initially, the Iowa Division of Criminal Investigation (DCI) only
tested for BAC, which came back below .04. See Iowa Code § 321J.2(1)(b)
(setting the legal limit as .08). A month later, DCI ran a second test covering
controlled substances—this test came back positive for amphetamine and
methamphetamine.
6
Wenzel moved to suppress the test for controlled substances. At the
suppression hearing, Wenzel conceded the stop of his car and the search warrant
were all above board. But, he argued, because the warrant was premised only on
reasonable suspicion that he was under the influence of alcohol, not controlled
substances, the second blood test was outside the scope of the search warrant
and violated both the Fourth Amendment of the Federal Constitution and article I,
section 8 of the Iowa Constitution. Conceding he was not trained as a drug
recognition expert,2 Deputy Syverson testified the basis of the application was
premised on the suspicion Wenzel had been drinking alcohol as those were the
overt signs observed. But he explained that asking for both tests is common
practice because of the difficulty with knowing if there is any other type of
substance causing an impairment in combination with alcohol use.
The district court ultimately denied the suppression motion. After reviewing
the application and the warrant, as well as hearing testimony from the deputy, the
district court found that probable cause existed because Deputy Syverson saw
Wenzel commit a traffic violation combined with observations of Wenzel’s condition
and considering his admission to drinking a beer earlier. The court noted “[a]ll of
these factors established probable cause for the issuance of the warrant.” Yet, the
district court determined that “the application for the warrant is devoid of any basis
[Wenzel] was operating a motor vehicle while impaired by something other than
alcohol.” Going further, the court said:
2 Deputy Syverson testified he was employed as a police officer for about five and
a half years in South Dakota and after his move, had served as a deputy in Iowa
for two and a half years.
7
Deputy Syverson did not include any facts to support that conclusion
within the narrative contained in the application, nor did he check any
of the items with respect to purported reasonable grounds to believe
[Wenzel] was under the influence of a controlled substance or drug.
Additionally, the application is devoid of any information upon which
to base a conclusion that Deputy Syverson is qualified to determine
whether a person is operating a motor vehicle while impaired by
drugs or controlled substances.
Still, the district court concluded Wenzel had no expectation of privacy in the
sample once the blood was drawn, finding the subsequent testing was not a
separate or distinct event under the Fourth Amendment. Thus, in the court’s view,
the drawing of Wenzel’s blood was the constitutionally significant event, and the
subsequent testing was not a violation of Wenzel’s privacy rights nor an
unreasonable search.
Following a trial on the minutes, Wenzel was found guilty. Wenzel now
appeals, arguing the district court erred in denying his suppression motion.
II. Analysis.
As framed by him, Wenzel’s claims come under the Fourth Amendment3 of
the Federal Constitution and article I, section 8 of the Iowa Constitution. They each
function “to protect personal privacy and dignity against unwarranted intrusion by
the State.” Schmerber v. California, 384 U.S. 757, 767 (1966); accord State v.
3 The Fourth Amendment of the Federal Constitution states:
The right of the people to be secure in their persons, houses,
papers, and effects, against unreasonable searches and seizures,
shall not be violated, and no Warrants shall issue, but upon probable
cause, supported by Oath or affirmation, and particularly describing
the place to be searched, and the persons or things to be seized.
The language of article I, section 8 of the Iowa Constitution is nearly identical,
though even the minor differences have been well debated. See State v. Gaskins,
866 N.W.2d 1, 6 (Iowa 2015) (discussing a semicolon present in the Iowa
Constitution not present in the Fourth Amendment).
8
King, 867 N.W.2d 106, 110–11 (Iowa 2015) (noting the privacy interests protected
by article I, section 8). Both protect against unreasonable searches and seizures
and require that a search warrant be based on probable cause. State v. Moriarty,
566 N.W.2d 866, 868 (Iowa 1997). A warrantless search is presumed
unreasonable, and when a defendant challenges a warrantless search, the State
bears the burden of proving the search falls into an exception such as consent or
exigent circumstances. Id.
Wenzel argues that the second test conducted on his blood was a
warrantless, unreasonable search that violated both his Fourth Amendment and
article I, section 8 constitutional rights. Because we are reviewing a motion to
suppress premised on the violation of a constitutional right, we employ de novo
review. See State v. Green, 896 N.W.2d 770, 775 (Iowa 2017) (“We look to the
entire record and ‘make “an independent evaluation of the totality of the
circumstances.”’” (citations omitted)). “On factual matters, we give deference to
the trial court, but we are not bound by its findings.” Id.
A. The Second Blood Test as a Separate Search.
As a preliminary step, we start with Wenzel’s argument that testing his blood
is a search that is distinct from the blood draw (which he concedes was properly
completed pursuant to the warrant). “[A] Fourth Amendment search occurs when
the government violates a subjective expectation of privacy that society recognizes
as reasonable.” Kyllo v. United States, 533 U.S. 27, 33 (2001); see also Katz v.
United States, 389 U.S. 347, 361 (1967) (Harlan, J., concurring) (“My
understanding of the rule that has emerged from prior decisions is that there is a
twofold requirement, first that a person have exhibited an actual (subjective)
9
expectation of privacy and, second, that the expectation be one that society is
prepared to recognize as ‘reasonable.’”). The Supreme Court has already
determined that blood draws and the subsequent chemical testing are a search.
See Skinner v. Ry. Lab. Execs.’ Ass’n, 489 U.S. 602, 616 (1989) (“We have long
recognized that a ‘compelled intrusio[n] into the body for blood to be analyzed for
alcohol content’ must be deemed a Fourth Amendment search.” (alteration in
original) (quoting Schmerber, 384 U.S. at 767–68); see also id. at 618 (“[T]he
collection and subsequent analysis of the requisite biological samples must be
deemed Fourth Amendment searches.”).
Still, Wenzel cannot point to an Iowa case that analyzes the initial draw and
the subsequent test as two distinct constitutional events. In a published case
decided by a panel of our court, we answered this question, with some
qualification, stating “though the issue has not been decided in Iowa, we note that
other courts have held that a defendant loses a privacy expectation in blood after
its lawful removal from the body, and therefore, any testing of that blood does not
violate the constitutional protections from unreasonable searches and seizures.”
State v. Frescoln, 911 N.W.2d 450, 456 (Iowa Ct. App. 2017) (listing cases in
various jurisdictions and other authority arriving at this conclusion), further review
denied (Jan. 31, 2018); see also Jacobson v. State, 603 S.W.3d 485, 490 (Tex.
App. 2020) (finding the defendant lost his expectation of privacy in blood seized to
investigate his intoxication while driving, so a second warrant was not needed for
subsequent testing, and listing other jurisdictions4 that found the same).

Without any Iowa authority to back him up, Wenzel points to language found
in Skinner, which states, “The ensuing chemical analysis of the sample to obtain
physiological data is a further invasion of the tested employee’s privacy interests.”
489 U.S. at 616. But while the blood draw and the subsequent testing together
invade the person’s body and privacy, these two pieces—the draw and the test—
work in tandem. See Frescoln, 911 N.W.2d at 456 (determining that a warrant for
a blood draw under section 321J.2 “implie[d] the blood sample would be subjected
to chemical testing”); Schmerber, 384 U.S. at 770 (allowing a warrantless blood
test because the specific facts created exigent circumstances); see also United
States v. Snyder, 852 F.2d 471, 473 (9th Cir. 1988) (“[The defendant] points out,
however, that the exigency justifying extraction of blood is eliminated once the
blood is removed from the suspect’s body, because any traces of alcohol in the
extracted blood will be preserved indefinitely. . . . Removal of blood from a
defendant’s blood stream eliminates immediately the danger that evidence of
blood-alcohol content will be lost. Thus, if [the defendant’s] argument were correct,
the results of the blood test in Schmerber would have been excluded because no
exigent circumstances remained by the time the test was actually conducted.”).
But there are fissures in Wenzel’s reliance on Skinner as outlined in State v.
Randall.
Every . . . search, of course, must have a constitutional justification.
But as . . . Skinner . . . demonstrate[s], the Court’s analytical
approach proceeds with the understanding there is only one search,
even though the government is both: (1) obtaining a biological
Swartz, 517 S.W.3d 40, 48–50 (Mo. Ct. App. 2017); People v. King, 663 N.Y.S.2d
610, 614 (N.Y. App. Div. 1997); State v. Price, 270 P.3d 527, 529 (Utah 2012);
State v. Martines, 355 P.3d 1111, 1116 (Wash. 2015); State v. Sanders, Nos. 93-
2284-CR, 93-2286-CR, 1994 WL 481723, at *5 (Wis. Ct. App. Sept. 8, 1994).
11
specimen; and (2) testing the specimen for the presence of alcohol.
Thus, the Skinner Court referred to a blood draw and test as involving
a single search: “We have long recognized that a ‘compelled
intrusio[n] into the body for blood to be analyzed for alcohol content’
must be deemed a Fourth Amendment search.” Although the Court
recognized in this sentence both the acquisition of the sample and
the subsequent analysis, the entirety of the Court’s reasoning
depended on there having been just one search. If the biological
specimen testing regimen in Skinner involved an invasion of two
distinct privacy interests, the Court would have been duty-bound to
assess the constitutional fidelity of each search separately. It did not.
Instead, it focused exclusively on the acquisition of the sample to be
tested. After the Court satisfied itself that the government had a
constitutionally-sufficient basis for obtaining the biological
specimens, it declared the testing regime sound.
930 N.W.2d 223, 230 (Wis. 2019) (fifth alteration in original) (internal citation
omitted).
Still, even in State v. Fawcett, which the district court here cited as
supporting the premise that an individual loses their right to privacy in their blood
sample after it is drawn, the court recognized that the tests would need to abide by
reasonableness standards. 877 N.W.2d at 561 (“Although such circumstances are
not before us, we note that Schmerber dictates that a standard of reasonableness
controls and that an unnecessary invasion of privacy interests would most certainly
raise concerns of reasonableness. . . . If the state lawfully obtains a blood sample
for the purpose of chemical analysis, then a chemical analysis of the sample that
does not offend standards of reasonableness is not a separate search requiring a
warrant.” (internal citations omitted)); see also Schmerber, 384 U.S. at 768
(analyzing if a blood draw and test “respected relevant Fourth Amendment
standards of reasonableness”). Even here, while arguing the blood draw and test
are not distinct constitutional events, the State concedes that the blood tests would
still be subject to search and seizure requirements of reasonableness.
12
Regardless of if we agree with Wenzel that the second blood test was a
distinct and separate constitutional event involving his reasonable expectation of
privacy and requiring a separate probable-cause review, our analysis of the
warrant process here, as explained below, convinces us it was constitutionally
reasonable for the warrant to authorize a search for controlled substances, in
addition to alcohol, and the testing at issue in this appeal was within that scope.
See Good v. Iowa Dep’t of Hum. Servs., 924 N.W.2d 853, 856 (Iowa 2019)
(employing constitutional avoidance by choosing not to answer the constitutional
question when another could determine the outcome).
B. The Scope of the Warrant and the Question of Probable Cause and
Reasonableness.
Wenzel starts by acknowledging a valid warrant was granted, but he argues
it (1) did not allow for a test for controlled substances or (2) even if it did allow for
the test for controlled substances, it lacked probable cause. To counter, the State
first argues that the warrant authorized the drug test and, beyond that, the warrant
application established probable cause of drugged driving so that a test for
controlled substances was reasonable.
The Fourth Amendment does not protect against all searches, but against
unreasonable ones. Carroll v. United States, 267 U.S. 132, 146 (1925). A search
without a warrant is per se unreasonable unless it fits into one of “a few specifically
established and well-delineated exceptions.” Katz, 389 U.S. at 357.5 Looking at
the actual warrant here, it allowed the officers to obtain “[a] blood, urine, and/or
5 The State does not argue an exception applies in this case.
13
breath specimen from [Wenzel]” because “[o]fficers have probable cause to
believe that a traffic violation under Iowa Code § 321J.2 has occurred and the
specimen(s) sought are/is relevant to a criminal investigation into a violation of
Iowa Code § 321J.2.” Section 321J.2 criminalizes operating while intoxicated by
either alcohol, controlled substances, drugs, or some combination thereof. On its
face then, the warrant allowed for the chemical analyses for alcohol, controlled
substances, and drugs.
Our analysis does not end there, however—Wenzel also argues the warrant
was not supported by probable cause specifically for controlled substances. “[A]s
a reviewing court, we do not independently determine probable cause and instead
‘merely decide whether the issuing judge had a substantial basis for concluding
probable cause existed.’” State v. McNeal, 867 N.W.2d 91, 100 (Iowa 2015)
(citation omitted). An “affidavit of probable cause is interpreted in a common
sense, rather than a hypertechnical, manner.” State v. Gogg, 561 N.W.2d 360,
364 (Iowa 1997). There is probable cause to issue a search warrant when “a
person of reasonable prudence would believe a crime was committed on the
premises to be searched or evidence of a crime could be located there.” Id. at 363
(citation omitted). “Probable cause to search requires a probability determination
that ‘(1) the items sought are connected to criminal activity and (2) the items sought
will be found in the place to be searched.’” Id. (citation omitted). “[W]e draw all
reasonable inferences to support the judge’s finding of probable cause and give
great deference to the judge’s finding,” and “[c]lose cases are decided in favor of
upholding the validity of the warrant.” McNeal, 867 N.W.2d at 100 (first alteration
in original) (citations omitted); cf. Illinois v. Gates, 462 U.S. 213, 236 (1983) (“‘A
14
grudging or negative attitude by reviewing courts toward warrants’ is inconsistent
with the Fourth Amendment’s strong preference for searches conducted pursuant
to a warrant.” (internal citation omitted)). In this analysis, we look only to “that
information, reduced to writing, which was actually presented to the [judge] at the
time the application for warrant was made.” McNeal, 867 N.W.2d at 100 (alteration
in original) (citation omitted).
Our preference is to uphold warrants and construe them in a common-
sense manner so that we resolve doubtful cases in favor of their validity. See State
v. Angel, 893 N.W.2d 904, 911 (Iowa 2017). So, we examine the application here
with that lens. While Wenzel draws our focus to the “Controlled Substances”
section of the warrant application, which Deputy Syverson left blank, we believe
common sense requires we examine all sections of the application. The warrant
paperwork is submitted in several parts. First, Deputy Syverson signed an
application for search warrant confirming “[o]fficers have probable cause to believe
that a traffic violation under Iowa Code § 321J.2 has occurred and the specimen(s)
sought are/is relevant to a criminal investigation into a violation of Iowa Code
§ 321J.2.” See Frescoln, 911 N.W.2d at 456 (addressing a warrant with the exact
same language and applying a “common sense” reading of the warrant). The
application also noted the “facts establishing the grounds for issuance of a search
warrant are as set forth in the attachments made a part of this application.” The
first attachment—“A-1 OBSERVATIONS ON SCENE”—contained standard
language:
Based on my training, education, experience, and discussions
with other members of law enforcement, I know the collection of a
specimen for forensic testing will aid my investigation and determine
15
what role the use of alcoholic beverages, controlled substances, or
drugs played in this traffic offense. Based on my training, education,
experience, and discussions with other members of law enforcement
I know that persons who have prior convictions for operating while
Intoxicated or who have been investigated for operating while
intoxicated on previous occasions are more likely to refuse chemical
testing.
Based on the following information, I have probable cause to
believe suspect has violated Iowa Code § 321J.2.
Thus, as an issuing judge, one could read the application as requesting a
blood draw to investigate the cause of the impaired driving supported by
observations of bloodshot and watery eyes, slurred speech, impaired judgment,
and poor driving. See State v. McIver, 858 N.W.2d 699, 703 (Iowa 2015) (noting
aberrant driving can raise a suspicion of impairment). A judge could also consider
that the objective observations checked by the deputy might support intoxication
by consumption of a controlled substance, drug, alcohol, or a combination of the
three. Partnered with those objective observations, an issuing judge would be
aware of “the reality that a peace officer may only begin to suspect drugs other
than alcohol may be involved to explain impaired driver conduct after a test geared
to detect the presence of alcohol fails to detect any alcohol or enough alcohol to
explain the impaired conduct.” See id. at 707. Our supreme court recognized the
limitations of detection involving impairment by drugs by noting these hurdles:
Unfortunately, there is no procedure comparable to the Standard
Field Sobriety Test that a police officer can administer on a roadside
to determine if a driver is under the influence of drugs. For example,
marijuana diminishes a person’s temporal and spatial judgment, but
the Standard Field Sobriety Test does not measure those effects.
Police officers also rely on nystagmus to determine if a person is
under the influence of alcohol, but drugs that dilate or constrict the
pupils do not also cause nystagmus.
16
State v. Childs, 898 N.W.2d 177, 184 (Iowa 2017) (quoting Paul J. Larkin Jr.,
Medical or Recreational Marijuana and Drugged Driving, 52 Am. Crim. L. Rev. 453,
483 (2015)). While objective observations, such as slurred speech, can be indicia
of intoxication by alcohol or by drugs, the more difficult task of identifying the
specific level of drug use to show impairment should not serve as an impediment
to enforcement. That is why the legislature’s harsh treatment of driving while
drugged “is ameliorated by the fact that the motorist would be asked to submit to
chemical testing only after the officer performed a lawful traffic stop and had
reasonable grounds to believe the driver was impaired.” Id. at 185. This kind of
tension is exactly the situation we face here.6 With impairment established by
objective signs, it is reasonable to allow for blood testing to determine the source
without having to know the specific source from the get-go. Unlike the district court,
we conclude the issuing judge had a substantial basis for concluding probable
cause existed to obtain Wenzel’s blood sample to test for controlled substances
and drugs as well as alcohol.
6 We recognize there are law enforcement officers trained specifically in drug
detection, but not all are. Still, as here, officers trained to spot impaired driving
should have the tools available to determine the cause. The importance of
removing impaired drivers from the road supports the reasonableness of testing
for substances that might have caused that impairment. After all,
[j]ust as a peace officer must possess reasonable grounds to believe
a driver is in violation of the statute, drivers possess common
knowledge that the consumption of alcoholic beverages and
controlled substances alter thinking and impair physical actions.
Persons of ordinary intelligence know that their conduct may be in
violation of the statute if they drive a motor vehicle after intoxicating
drugs are consumed.
State v. Newton, 929 N.W.2d 250, 257 (Iowa 2019).
17
As further support for his probable-cause argument, Wenzel points to the
suppression court’s conclusion that Deputy Syverson gave no factual support in
the application that Wenzel was impaired by drugs or controlled substances. At
that hearing, Deputy Syverson was less than clear about his suspicions over the
cause of Wenzel’s impairment. When questioned, he testified:
Q. Now when you sent the specimen to the Iowa DCI, why did
you check for a drug screen in addition to an alcohol or ethanol
screen? A. Because when we take a sample, we test everything that
we can on that sample to get a true and accurate representation of
what’s going on.
Q. And I understand that. But you did so without any facts or
reasonable basis in the suspicion that he was under the influence of
a controlled substance; correct? A. Well, impairment can be caused
by both alcohol and other drugs. Based on not having any field
sobriety tests or a breath test or anything, I believed there was
impairment. And the main cause I believed was alcohol at the time,
but I had no way of ruling out any other kind of impairment.
Q. Come on now, though. In your application to the Court you
didn’t mention anything about a suspicion of drug impairment, did
you? A. I did not.
Q. And there’s specific boxes there for that; correct? A. Yes,
there is.
Q. And so you sent that blood sample to the lab requiring a
drug screen; correct? A. Correct.
Q. But you didn’t mention a single word of any suspicion of
drugs in your application to [the issuing judge], did you? A. I did not.
Yet, the deputy also answered “Yes, it can” when asked if some of the signs of
impairment could also be caused by use of a controlled substance. While Deputy
Syverson’s testimony at the suppression hearing was that he had no suspicion
Wenzel was under the influence of controlled substances to voice to the issuing
judge, this is not reflected in the pages of the written application. See State v.
Thomas, 540 N.W.2d 658, 662 (Iowa 1995) (explaining that in reviewing the
outcome of a suppression hearing concerning the sufficiency of a warrant, the
reviewing “court may not consider any other relevant information present in the
18
record which was not presented to the neutral magistrate issuing the warrant”).
Important here, while the suppression hearing judge did not account for this
testimony describing the difficulty to establish the specific cause of the impairment
in the field, it cannot be disputed that the question of impairment was established
for probable cause purposes. The lack of additional information in the controlled
substances section of Attachment A-2 does not undermine the full application’s
goal of seeking intoxicants to determine the cause of impairment.
True, Deputy Syverson’s preliminary judgment was that alcohol created
Wenzel’s intoxication, but “[p]robable cause is not the same standard as beyond a
reasonable doubt. Probable cause may exist even if the officer’s perception of the
traffic violation was inaccurate.” State v. Tyler, 830 N.W.2d 288, 293 (Iowa 2013)
(viewing the stop from the standpoint of an objectively reasonable officer). Here,
Deputy Syverson had an objective reason to believe Wenzel was driving while
impaired and that some measure of alcohol might be the cause or part of the
cause. A full review of the application describes the intoxicants sought as alcohol,
controlled substances, or drugs; based on the four corners of the warrant
application, a person of reasonable prudence would believe Wenzel was driving
while intoxicated and the intoxicants would probably be found in Wenzel’s blood.
Deputy Syverson was not trained as an expert in drug recognition, but he was
trained to recognize physical signs of a driver’s impairment, which Wenzel
exhibited.
So, returning to our common-sense analysis, we consider the totality of the
circumstances that are presented in the warrant application and “ask whether the
common-sense inferences a person may draw from them would lead ‘a person of

reasonable prudence [to] believe . . .evidence of a crime could be located’ in the
place to be searched.” McNeal, 867 N.W.2d at 102 (alterations in original) (citation
omitted). And again, “we draw all reasonable inferences to support a court’s
finding of probable cause.” State v. Davis, 679 N.W.2d 651, 656 (Iowa 2004). We
do not make an independent determination of probable cause but look to the
information, reduced to writing, available to the warrant judge to see if there was a
substantial basis for finding the existence of probable cause. Id. The issuing judge
would have considered that Wenzel’s traffic offense involved impaired judgment
by failing to yield to an emergency vehicle, that Wenzel had bloodshot and glassy
eyes and slurred speech, and that Wenzel rejected all field sobriety tests. With an
admission to drinking only one beer, it was reasonable for an issuing judge to
support further investigation into the cause of Wenzel’s impairment beyond alcohol
consumption because impairment might be caused by a combination of alcohol
and other substances. As such, the warrant ordered future testing of the blood
that would aid the investigation and “determine what role the use of alcoholic
beverages, controlled substances, or drugs played in the traffic offense.” This
information contained in the affidavit was sufficient to find probable cause to test
Wenzel’s blood to determine what role the substances listed might play in
committing the traffic offense.
In sum, we find there was probable cause to do a blood draw and it was
reasonable to test the blood for alcohol, controlled substances, and drugs. Finally,
we note that Wenzel takes issue with the second test as being overbroad because
the lab ran screens on fifteen different panels. But the warrant did not limit the
types of intoxicants that could be tested—we find the use of those screens was to
20
establish the reason behind the observed impairment of Wenzel and not for some
other crime-related fishing expedition. And, in all fairness, in some cases the
testing profile could actually exonerate a driver. See State v. Myers, 924 N.W.2d
823, 831 (Iowa 2019) (“Impaired conduct can be consistent with the presence of a
controlled substance, but it can also result from a medical condition or other
causes unrelated to the consumption of a controlled substance.”).
C. Article I, Section 8.
As a final argument, Wenzel attempts to utilize our supreme court’s
prerogative to “jealously guard [the] right to construe a provision of our state
constitution differently than its federal counterpart, though the two provisions may
contain nearly identical language and have the same general scope, import, and
purpose.” State v. Brown, 930 N.W.2d 840, 847 (Iowa 2019) (citation omitted).
“Even where a party has not advanced a different standard for interpreting a state
constitutional provision, we may apply the standard more stringently than federal
case law.” State v. Pals, 805 N.W.2d 767, 771–72 (Iowa 2011). Wenzel asks that,
if we do not believe the search violates his rights under the Fourth Amendment,
we should find it violates his rights under article I, section 8 of the Iowa Constitution.
But, even earlier this year, our supreme court has continued to use the
same analysis for the review of search warrants as our federal counterparts. See
State v. Bracy, 971 N.W.2d 563, 568–70 (Iowa 2022) (refusing to dissect a
“warrant, examining it bit-by-bit” and throw out parts that do not establish probable
cause on their own); but see id. at 574 (Appel, J., dissenting) (“Bracy does not,
however, suggest that the substantive standards to be applied in this case under
the Iowa Constitution are different from those articulated by the United States
21
Supreme Court under the Fourth Amendment. As a result, under our precedent,
we apply the prevailing federal standards, but we reserve the right to apply those
standards in a fashion that differs from federal caselaw for the purposes of this
case.” (footnote omitted)).7 Because our supreme court has remained consistent
with federal jurisprudence in reviewing warrants, we will not deviate from the
course. We hold the warranted blood draw and test did not violate Wenzel’s article
I, section 8 constitutional rights.
III. Conclusion.
We affirm Wenzel’s conviction and sentence on the basis that the test of his
blood for controlled substances and drugs was both allowed under the warrant and
supported by probable cause.
AFFIRMED.
7 In addition to Bracy, our supreme court decided State v. Wright, 961 N.W.2d 396
(Iowa 2021), which involved a warrantless search of the contents of Wright’s trash.
In Wright, a plurality of the court outlined a process for determining whether a
search had occurred—rather than using an individual’s privacy expectation to
determine whether State action was a search, that privacy expectation impacts
only if the search is reasonable. Wright, 961 N.W.2d at 414 (plurality opinion).
While Wenzel argues Wright should change the result here, we disagree because
this search was conducted pursuant to a warrant and that the search was
reasonable.
