Heard at oral argument by Greer, P.J., and Badding and Chicchelly, JJ. 2
GREER, Presiding Judge.
Donna Cox was charged with possession of controlled substance
(methamphetamine) after officers discovered methamphetamine and drug
paraphernalia on her person and in her car. The drug investigation yielding
evidence of the possession of methamphetamine started as a traffic stop for a
broken taillight and crossing the center line while driving, but after a canine alerted
to the presence of an illicit substance, officers searched Cox’s vehicle. Cox argues
that officers impermissibly prolonged the traffic stop by implementing a “systematic
approach” where “the canine officer intentionally delays the issuance of tickets by
calling another officer to the scene of traffic violation to complete the writing or
paperwork required for a ticket, so the initial officer can unlawfully extend the stop
in an attempt to gain probable cause to search the vehicle.”
After review of the record, we find Officers Skyler Verros and Joseph
Weppler did not impermissibly extend the traffic stop. Thus, we affirm the denial
of the motion to suppress.
Background Facts and Proceedings.
Cox claims a drug investigation incident to a traffic stop, where probable
cause to search was established by a canine free air sniff, violated her state and
federal constitutional rights. The district court summarized the pertinent facts as
follows:
On June 16, 2022 Sergeant Skyler Verros (“Verros”) of the Knoxville Police Department was on routine patrol. In addition to being a Sergeant, Verros is also a K9 handler. Verros’ K9 partner is named Rosko. Rosko and Verros have been partners for approximately two (2) years. . . . Rosko is a passive alert K9. He indicates the detection of narcotics by sitting during a deployment. 3
On June 16th, . . . Verros was patrolling within the city limits of Knoxville, when he observed a silver minivan traveling in the opposite direction of him. As the vehicles drove past each other, Verros observed the driver of the minivan, who Verros knew to be Jason Vaughn. Verros then turned his vehicle around to follow the minivan and run an administrative check of the vehicle. Before Verros could run the check, he observed two motor vehicle violations, a defective third break light, and the driver operating the vehicle in the opposite lane of traffic. Upon viewing these violations, Verros activated the lights on his patrol car and initiated a traffic stop of the vehicle. During the suppression hearing, several questions were directed to Verros, by counsel for the defendants, about his reason for following the vehicle. Verros admitted that he had decided to follow the vehicle to see if he could develop either probable cause or reasonable suspicion sufficient to stop the vehicle. Verros had previously explained at a deposition, and subsequently confirmed at the suppression hearing, that he had developed a system to deploy his K9 following a traffic stop, to check for the presence of narcotics. Based on prior knowledge of Vaughn being associated with illegal narcotics, Verros made the determination upon observing Vaughn driving the minivan, that Verros would follow the vehicle and see if he could develop grounds to stop the vehicle and deploy K9 Rosko. After stopping the minivan and approaching the driver’s side of the vehicle, Verros confirmed Vaughn was driving. Verros also observed . . . Cox sitting in the passenger seat of the van. Verros requested the license of Vaughn and registration and proof of insurance for the vehicle. Vaughn was able to produce a valid driver’s license, but after approximately three (3) to four (4) minutes of searching, Cox could not come up with current proof of insurance for the vehicle. Verros then returned to his patrol car to issue a warning for one of the traffic violations and a citation for no insurance. Pursuant to Verros’ system, he had called [Weppler] to come to the scene, at the beginning of the traffic stop. Weppler arrived as Verros was finishing the warning but prior to completing the citation for no insurance. Weppler then took over issuing the no insurance citation while Verros deployed Rosko to sniff for the presence of narcotics around the exterior of the vehicle. Rosko made several passes around the vehicle before finally giving an indication for the presence of narcotics in the vehicle. Weppler was finishing the citation for no insurance at approximately the same time as Rosko indicated the presence of narcotics. The elapsed time from the stop of the minivan to the time Rosko established probabl[e] cause for the presence of a controlled substance, was approximately eleven (11) minutes. 4
After Rosko’s signal, Verros and Weppler asked Cox to step outside the vehicle so
the officers could search the vehicle for methamphetamine. Weppler found a pipe
with methamphetamine residue in Cox’s front pocket. During a search of the
vehicle, officers found methamphetamine and methamphetamine residue in the
vehicle. Both Cox and Vaughn were arrested and charged.
Cox filed a motion to suppress, arguing the search of her vehicle incident to
the traffic stop violated her rights under article I, section 8 of the Iowa Constitution
and the Fourth Amendment of the United States Constitution. The district court
denied her motion to suppress, finding the search did not violate Cox’s state or
federal constitutional rights.
Cox proceeded to an agreed-upon trial on the minutes where the district
court found her guilty of possession of controlled substance (methamphetamine),
first offense, a serious misdemeanor. Cox received a sentence of 120 days in jail,
with all 120 days suspended, and one year of probation as part of a global
judgment entry for this charge and five other unrelated offenses. She was also
required to pay fines and surcharges on each of her six criminal convictions.
Cox appeals the denial of her motion to suppress.

suppress based upon the deprivation of a state or federal constitutional right, our

“When a defendant challenges a district court’s denial of a motion to
suppress based upon the deprivation of a state or federal constitutional right, our
standard of review is de novo.” State v. Coffman, 914 N.W.2d 240, 244 (Iowa

determined by “evaluat[ing] the totality of the circumstances as shown by the entire

fact, “[e]ach case must be evaluated in light of its unique circumstances.” Coffman,
914 N.W.2d at 244 (citation omitted).
Discussion.
Cox contends that both the Iowa and United States Constitutions support
her assertions, but she fails to delineate any difference between the standards in
state and federal jurisprudence. “Article I, section 8 guarantees the right to be
secure against unreasonable searches and seizures, and it contains language
nearly identical to the Fourth Amendment counterpart.” State v. Salcedo, 935
N.W.2d 572, 577 (Iowa 2019). “We generally interpret the scope and purpose of
the Iowa Constitution’s search and seizure provisions to track with federal
interpretations of the Fourth Amendment because of their nearly identical
language.” State v. Brown, 930 N.W.2d 840, 847 (Iowa 2019) (cleaned up). “When
both federal and state constitutional claims are raised, we may, in our discretion,
choose to consider either claim first in order to dispose of the case, or we may
consider both claims simultaneously.” Salcedo, 935 N.W.2d at 577 (citation
omitted). Because Cox does not make independent state and federal claims, we
consider her constitutional claims simultaneously.
Cox begins her challenge by asserting the stop of her vehicle was
“pretextual,” yet she acknowledges that the motivation of the officer stopping the
vehicle is not controlling in determining whether probable cause existed. See
Brown, 930 N.W.2d at 854 (“[W]e made clear that an officer’s ulterior motive for
making the arrest does not limit the right to conduct a search incident thereto under
the Iowa Constitution if probable cause exists for an arrest to be made.” (cleaned
up)). From that statement, Cox’s focus turns to the process Verros used to allow 6
for a drug dog sniff. Cox seems to recognize that the initial traffic stop was
permissible. See Whren v. United States, 517 U.S. 806, 810 (1996) (“As a general
matter, the decision to stop an automobile is reasonable where the police have
probable cause to believe that a traffic violation has occurred.”); Salcedo, 935
N.W.2d at 577 (“It is well settled that a traffic violation, however minor, gives an
officer probable cause to stop a motorist and is therefore a reasonable seizure.”
(cleaned up)). And she does not contest that a free air dog sniff is allowed without
independent reasonable suspicion if the sniff does not prolong the traffic stop. See
generally Illinois v. Caballes, 543 U.S. 405 (2005); State v. Arrieta, 998 N.W.2d
617, 619 (Iowa 2023) (“Officers are allowed to use a drug dog to conduct a ‘free
air sniff’ around the outside of a vehicle during a valid traffic stop without any
suspicion that the vehicle contains drugs under the premise that the driver has no
expectation of privacy in the air outside the vehicle.”). From our review, the traffic
violation was observed on Verros’s car camera video, making the initial stop
justified. So we turn to Cox’s argument over the permissibility of a system she
characterized as the initial officer’s systematic approach.
This initial officer systematic approach, as described by Cox, involves a
canine officer purposefully stalling a traffic stop while writing citations and calling
for a second officer, who responds and takes over writing citations, thereby freeing
the initial canine officer to conduct a free-air sniff. As Cox notes, “[s]imply put, the
initial officer is attempting [to] extend a traffic stop without separate probable cause
other than the original traffic offenses by intentionally slowing down the ticket
issuing process to permit the dog sniff search.” Cox urges that this unconstitutional
system need to be “stopped by the courts.” The suppression court also expressed 7
reservations about the process used by Verros at the overall complexion of the
stop as it
would offer in speculation that the current state of the law [that the motivation of the officer is irrelevant with a valid traffic stop] may not always be the case. Given recent societal focus on profiling, and even some recent legislative efforts to prevent such conduct, it is not beyond this Court’s imagination that in the not-too-distant future there could be a shift of focus to an officer’s subjective reasons for singling out an individual for investigation. Lawmakers may come to recognize that an “ends justifies the means” approach to investigations may cause an otherwise well-intentioned investigation to be tainted by fixed, preconceived ideas that a person is guilty, before any proof is adduced. That shift in focus could be expedited by law enforcement’s systematic and routine use of relying on minor objective reasons for investigation, to support subjective hunches based on a profile. But that is a discussion for another time and in another arena.
Cox contends that the initial officer systematic approach violates the precept that
“when the reason for a traffic stop is resolved and there is no other basis for
reasonable suspicion” the officer must allow a motorist to leave. State v. Coleman,
890 N.W.2d 284, 301 (Iowa 2017). And, Cox argues, the process used here
delayed and extended the stop. We start with this last point.
The Initial Officer Systematic Approach.
We turn to Cox’s central focus that the scheme used by Verros results in a
constitutional problem that should trigger the exclusionary rule. See Herring v.
United States, 555 U.S. 135, 144 (2009) (“[T]he exclusionary rule serves to deter
deliberate, reckless, or grossly negligent [police] conduct, or in some
circumstances . . . systemic negligence.”). As an issue of first impression, Cox
argues the system—which includes the exchange of Weppler for Verros when
writing a citation—constitutes the prolonging of a traffic stop. She contends, “The
sole purpose of calling a second officer to actually write the ticket is to circumvent 8
the limits placed on the officers by” article I, section 8 of the Iowa Constitution and
the Fourth Amendment to the Federal Constitution. But because the officer swap
did not cause an impermissible delay and is consistent with activities found in a
reasonable traffic investigation, we find no violation.
As for the pertinent facts, Verros and Weppler were efficient in swapping
places in the patrol vehicle. Weppler appeared alongside the vehicle; Verros
mentioned he had just completed the warning for the traffic offense but had not
completed the citation for no insurance. Verros then promptly left the vehicle and
Weppler picked up where Verros left off, inputting information on the patrol laptop
to complete the citation. Leaving the area around the patrol vehicle, Verros
completed a canine free air sniff with canine Rosko. Weppler finished scanning in
a signature to the citation, completing the citation, mere seconds after Rosko
finished.
An officer may not “earn bonus time to pursue an unrelated criminal
investigation” by completing traffic-related offenses expeditiously. Rodriguez v.
United States, 575 U.S. 348, 357 (2015). And “[a]uthority for the seizure . . . ends
when tasks tied to the traffic infraction are—or reasonably should have been—
completed.” Id. at 354. “If an officer can complete traffic-based inquiries
expeditiously, then that is the amount of ‘time reasonably required to complete [the
stop’s] mission.’” In re Pardee, 872 N.W.2d 384, 393 (Iowa 2015) (alteration in
original) (quoting Rodriguez, 575 U.S. at 356–57).
In this matter, as part of our de novo review, we reviewed both Verros’s and
Weppler’s bodycam footage for any signs of purposeful and impermissible
sluggishness. Both Verros and Weppler added information into a citation template 9
without obvious procrastination or delay. Weppler struggled to scan in a signature
to the citation, completing what appeared to be this final task seconds after canine
Rosko completed his effort. The district court noted that the entire stop took
approximately eleven minutes; on our review of the body camera footage,
Weppler’s completion of the ticket took just short of four minutes and canine
Rosko’s work took approximately two minutes during the time Weppler finished the
citation. Verros conducted the dog sniff during the time Weppler was still
completing the citation. We find no evidence that Weppler was stalling, as he
worked dutifully to complete the citation. We add, although the two officers worked
on the warning and citation successively, we cannot find the mere presence of two
officers delayed the “mission of the stop.” See id. at 396. Verros and Weppler, by
completing the warning and the citation as a team, did not impermissibly prolong
the traffic stop.
The law prohibits the unreasonably prolonging of a traffic stop “longer than
is necessary to effectuate that purpose.” Rodriguez, 575 U.S. at 354 (cleaned up).
“Ordinary inquiries incident to the traffic stop” are permissible. See id. at 355
(cleaned up). Examples of permissible inquiries include “checking the driver’s
license, determining whether there are outstanding warrants against the driver,
and inspecting the automobile’s registration and proof of insurance.” Id. We also
allow officers to “take certain negligibly burdensome precautions in order to
complete [the] mission safely,” as officer safety remains a paramount concern. Id.
at 356. “Once lawfully stopped, inquiries reasonably related to the mission of
addressing the traffic infraction and attending to related safety concerns are
permissible.” Salcedo, 935 N.W.2d at 578. “[T]he Fourth Amendment will tolerate 10
certain unrelated investigations that do not extend the roadside stop, but the stop
will remain lawful only ‘so long as [unrelated] inquiries do not measurably extend
the duration of the stop.’” Id. at 579 (second alteration in original) (quoting
Rodriguez, 575 U.S. at 355).
Under these facts, we think the officer “swap” is a negligibly burdensome
act that falls under acts normally found during permissible investigations or
“incident to a traffic stop.” Rodriguez, 575 U.S. at 355. Officers often work in pairs,
whether to train, expedite tasks, or ensure safety. To find that officers may not
swap tasks during a traffic stop would impinge the ability of officers to act in
accordance with what the situation demands. See id. at 356. The momentary
delay was not a violation of Cox’s constitutional rights.
Conclusion.
We affirm the denial of Cox’s motion to suppress.
AFFIRMED.
