Summary

The Kansas Court of Appeals affirmed a lower court's decision in State v. Knox, upholding the denial of a motion to suppress evidence in a DUI case. The court found that the deputy had reasonable suspicion to extend the traffic stop based on observations of open containers and the odor of alcohol.

What changed

The Kansas Court of Appeals issued a non-precedential opinion in the case of State v. Knox, affirming the district court's denial of the appellant's motion to suppress evidence. The court found that the deputy's observations, including an open box of beer in the backseat, an open can of beer at the driver's feet, and the odor of alcohol, provided reasonable suspicion to extend a traffic stop for speeding into a DUI investigation. The appellant was subsequently arrested for DUI, transporting an open container, and driving without proof of insurance.

This ruling means that the evidence obtained during the extended traffic stop is admissible. For compliance officers, this case reinforces the legal standard for reasonable suspicion in DUI investigations, emphasizing that a combination of factors, even if individually minor, can collectively justify an extended stop. Regulated entities, particularly those involved in transportation or hospitality where alcohol consumption might be relevant, should ensure their employees are aware of the legal parameters surrounding traffic stops and DUI investigations.

What to do next

  1. Review internal policies regarding traffic stop extensions and DUI investigations for compliance with reasonable suspicion standards.

State v. Knox

Court of Appeals of Kansas

Combined Opinion

NOT DESIGNATED FOR PUBLICATION

No. 128,624

IN THE COURT OF APPEALS OF THE STATE OF KANSAS

STATE OF KANSAS,
Appellee,

v.

DALTON KNOX,
Appellant.

MEMORANDUM OPINION

Appeal from Greenwood District Court; PHYLLIS K. WEBSTER, magistrate judge. Submitted
without oral argument. Opinion filed March 20, 2026. Affirmed.

Nathan M. Geffre, of Hulnick, Stang, Gering & Leavitt, P.A., of Wichita, for appellant.

Andrew J. Lohmann, assistant solicitor general, and Kris W. Kobach, attorney general, for
appellee.

Before BOLTON FLEMING, P.J., ISHERWOOD and COBLE, JJ.

PER CURIAM: Dalton Knox was pulled over for speeding by a Greenwood County
deputy. The deputy observed an open box of beer in Knox's back seat, an open can of
beer at his feet, and observed the odor of alcohol on Knox's person. Knox also made a
statement that he had consumed four or five beers that evening. Based on these facts, the
deputy extended the traffic stop into an investigation for the crime of driving under the
influence of alcohol (DUI). The investigation resulted in Knox's arrest for DUI.

1
As the case proceeded to trial, Knox filed a motion to suppress. Knox argued that
the deputy lacked reasonable suspicion to extend his traffic stop into a DUI investigation.
The district court denied the motion to suppress and held a bench trial on stipulated facts,
where Knox referenced the testimony at the motion to suppress hearing wherein he had
raised the issue of reasonable suspicion.

The district court found Knox guilty of speeding, driving under the influence,
transporting an open container, and no proof of insurance. Knox appeals, arguing the
district court erred in denying his motion to suppress.

After a thorough review of the record, we find that reasonable suspicion supported
the deputy's extension of the traffic stop into a DUI investigation. Considering the totality
of the circumstances, the deputy's observations provided him with reasonable suspicion
that Knox had committed the crime of DUI. The district court did not err in denying
Knox's motion to suppress, and accordingly, we affirm.

FACTUAL AND PROCEDURAL BACKGROUND

On November 25, 2023, Greenwood County Deputy Blake Fisher observed Dalton
Knox driving 69 miles per hour in a 60 miles per hour zone. Deputy Fisher pulled Knox
over for speeding, approached the vehicle, and noticed that the driver-side window was
only partially rolled down. Deputy Fisher spoke with Knox through the window and
observed an open box of beer in the backseat and an open can of beer at Knox's feet.
Deputy Fisher also noted the area around Knox's feet was wet.

Deputy Fisher was initially unable to observe any odor of alcohol due to the
partially opened driver side window, so he instructed Knox to step out of the vehicle. As
Knox exited the vehicle, Deputy Fisher smelled the odor of alcohol. Deputy Fisher
informed Knox that he was not under arrest at that time and asked Knox to sit in the

2
passenger seat of the patrol vehicle for further questioning. During this questioning, Knox
informed Deputy Fisher that he had been arrested when he was 18 years old for the crime
of minor in possession of alcohol, and when he was 21 years old for DUI. Knox also
admitted to having "four to five" beers before the traffic stop.

Deputy Fisher conducted a field sobriety test and then arrested Knox for DUI.
Later, a breathalyzer sample was taken from Knox which was over the legal limit. Knox
was charged with speeding under K.S.A. 8-1558; DUI under K.S.A. 8-1567; transporting
an open container under K.S.A. 8-1599; and no proof of insurance under K.S.A. 40-3104.

As his case progressed, Knox filed a motion to suppress the evidence in his case,
arguing that Deputy Fisher did not have reasonable suspicion to conduct the DUI
investigation. The district court denied the motion, specifically noting the open beer can
at Knox's feet.

The case proceeded to a bench trial on stipulated facts where Knox again
referenced his motion to suppress. The court considered the stipulated facts as well as the
testimony from the suppression hearing and found Knox guilty of speeding, DUI,
transporting an open container, and no proof of insurance.

Knox timely appeals.

ANALYSIS

DID DEPUTY FISHER HAVE REASONABLE SUSPICION TO INVESTIGATE KNOX FOR DUI?

Knox raises a single issue on appeal. While Knox acknowledges that Deputy
Fisher had reasonable suspicion to stop his vehicle for speeding, he argues the evidence
does not support Fisher's extension of that stop to complete a DUI investigation. Knox

3
argues that the district court erred in denying his motion to suppress based on this
argument.

Standard of Review

This court reviews the district court's denial of a motion to suppress using a
bifurcated standard of review. An appellate court determines whether the district court's
findings are supported by substantial competent evidence and then reviews the ultimate
legal conclusion de novo. State v. Garrett, 319 Kan. 465, 469, 555 P.3d 1116 (2024). In
this case, since the facts are generally uncontroverted, the ultimate question is a question
of law reviewed de novo. State v. Mendez, 319 Kan. 718, 735-36, 559 P.3d 792 (2024).

Discussion

The Fourth Amendment to the United States Constitution and section 15 of the
Kansas Constitution Bill of Rights protects the people from unreasonable searches and
seizures. U.S. Const. amend. IV; Kan. Const. Bill of Rights, § 15. These provisions
require that police officers must obtain a warrant before conducting a search or seizure
unless an exception to the warrant requirement applies. State v. Doelz, 309 Kan. 133, 140,
432 P.3d 669 (2019). One of those exceptions is an investigatory detention, or a Terry
stop. State v. Bates, 316 Kan. 174, 182, 513 P.3d 483 (2022); see Terry v. Ohio, 392 U.S.
1, 30
, 88 S. Ct. 1868, 20 L. Ed. 2d 889 (1968).

"[I]nvestigatory detentions are constitutionally permissible if an objective officer
would have a reasonable and articulable suspicion that the detainee committed, is about
to commit, or is committing a crime." State v. Hanke, 307 Kan. 823, 828, 415 P.3d 966
(2018). A traffic stop is an investigatory detention that must be justified by reasonable
suspicion. State v. Arrizabalaga, 313 Kan. 323, 330, 485 P.3d 634 (2021). Extending a
traffic stop beyond the purpose of the original stop requires "an objectively reasonable

4
and articulable suspicion that criminal activity was or is taking place." State v. Jones, 300
Kan. 630, 641
, 333 P.3d 886 (2014). Reasonable suspicion is a lower standard than
probable cause, and what is reasonable is dependent on the totality of the circumstances
in the view of a trained law enforcement officer. State v. Sharp, 305 Kan. 1076, 1081,
390 P.3d 542 (2017).

Here, the evidence before the district court was largely uncontroverted. Deputy
Fisher stopped Knox's vehicle for speeding. As he approached Knox's vehicle, Deputy
Fisher noticed that Knox's window was only partially rolled down. As a result, Deputy
Fisher was unable to observe any odor of alcohol. Still, Deputy Fisher was able to
observe an open box of Busch Light in Knox's back seat and an open beer can at Knox's
feet. Deputy Fisher also noticed that the floor near the open beer can was wet. Deputy
Fisher testified that he believed at this point he had probable cause to arrest Knox based
on transporting an open container of alcohol.

Deputy Fisher asked Knox to step out of the vehicle. Once out of the vehicle,
Deputy Fisher observed the odor of alcohol. Deputy Fisher informed Knox he wasn't
under arrest but asked him to sit in front passenger seat of the patrol car. While speaking
with Knox, Deputy Fisher learned that Knox had been previously arrested for minor in
possession of alcohol at age 18 and DUI at age 21. During this conversation, Knox also
admitted to having "four to five" beers before the traffic stop.

Deputy Fisher did not observe slurred speech, difficulty in communicating,
bloodshot eyes, slow or sluggish movements, or any other indicators consistent with
impairment. But it is uncontroverted that Deputy Fisher observed an open beer box in
Knox's back seat, an open beer can at Knox's feet, and the odor of alcohol coming from
Knox's person. And Knox admitted to drinking prior to the stop. We must then consider
whether this evidence, observed by Deputy Fisher at the time he stopped Knox, created
"an objectively reasonable and articulable suspicion that criminal activity was or is taking

5
place" that would justify the extension of the traffic stop into a DUI investigation. Jones,
300 Kan. at 641.

First, Deputy Fisher observed an open can of beer at Knox's feet. Knox's actions in
transporting an open container of alcohol may be considered in determining whether
there was reasonable suspicion he was driving under the influence. State v. Wagner, No.
112,730, 2015 WL 6620621, at *9 (Kan. App. 2015) (unpublished opinion) (finding
transporting open containers of alcohol were properly considered as evidence of DUI).

Knox argues that an open container alone does not create reasonable suspicion. In
support, Knox cites State v. Krinhop, No. 118,000, 2018 WL 2994290, at *1-2 (Kan.
App. 2018) (unpublished opinion). In Krinhop, the defendant struck a peacock with his
vehicle. The owner of the peacock observed Krinhop holding a can of beer in his hand as
he stepped out of his vehicle. Krinhop was later charged and convicted of DUI. A panel
of our court examined whether Krinhop's possession of an open container of alcohol
constituted reasonable suspicion to conduct a DUI investigation. The panel noted that the
deputy investigating the DUI could not articulate any other fact supporting reasonable
suspicion other than the peacock owner's observation and found the district court erred in
failing to grant Krinhop's motion to suppress. 2018 WL 2994290, at *2.

Knox's situation is distinguishable from Krinhop. Here, rather than a third party,
Deputy Fisher personally observed the open beer at Knox's feet and the spilled liquid on
the driver's side floorboard. And unlike in Krinhop, the open container was not the sole
evidence utilized to determine reasonable suspicion. The open container of alcohol
present in Knox's vehicle was properly considered by Deputy Fisher as part of the totality
of circumstances supporting reasonable suspicion.

Similarly, the presence of an open box of beer in a defendant's vehicle may be
considered as part of an officer's reasonable suspicion that the driver is currently under

6
the influence of alcohol. See State v. McGinnis, 40 Kan. App. 2d 620, 628, 194 P.3d 46
(2008) (12-pack of beer in front seat considered as part of a reasonable suspicion
analysis). It is undisputed that Deputy Fisher observed an open box of Busch Light in
Knox's back seat at the time he pulled Knox over.

Kansas courts have also found that the odor of alcohol is enough to extend a traffic
stop into a DUI investigation. See State v. Johnson, 46 Kan. App. 2d 387, 391, 264 P.3d
1018
(2011). In Johnson, a panel of our court considered whether a traffic stop was
lawfully extended into a DUI investigation. The panel noted that the validity of the
underlying stop was not contested. The panel concluded that "once Johnson's vehicle was
lawfully stopped, Campbell's detection of the odor of alcohol on Johnson's breath
provided sufficient grounds to extend the scope and duration of the stop." 46 Kan. App.
2d at 391
. Similarly, while Deputy Fisher initially could not observe the odor of alcohol
because Knox only partially rolled his window down, he was able to observe the odor of
alcohol once Knox exited the vehicle.

Knox's admission to drinking four or five beers the night of the stop also properly
contributed to Deputy Fisher's reasonable suspicion that Knox was driving while
intoxicated. See State v. Pollman, 286 Kan. 881, 895, 190 P.3d 234 (2008) (defendant's
admission to drinking a few beers properly considered as part of the totality of
circumstances supporting reasonable suspicion).

Knox asks us to consider State v. Mosier, No. 123,715, 2021 WL 3573842, at *1
(Kan. App. 2021) (unpublished opinion). In Mosier, a panel of this court found that a
deputy lacked reasonable suspicion to extend a traffic stop into a DUI investigation
because Mosier's admission of drinking alcohol did not specify the timing of his drinking.
2021 WL 3573842, at *6. The court also noted that Mosier showed no signs of
impairment, and the deputy observed no traffic infractions. But in comparison, here
Deputy Fisher did not rely on only an admission of drinking to begin the DUI

7
investigation. As explained above, his suspicion was based on other observations,
including the odor of alcohol, an open container of alcohol at Knox's feet, a wet
floorboard, and an open box of Busch Light in the back seat.

We conclude this analysis by reviewing the totality of the circumstances. Knox
agrees that his traffic stop was legal. He argues that under the totality of circumstances,
there was no reasonable suspicion to extend that traffic stop into a DUI investigation. We
reiterate the standard that the extension of a traffic stop into a DUI investigation requires
"an objectively reasonable and articulable suspicion that criminal activity was or is taking
place." Jones, 300 Kan. at 641. Reasonable suspicion depends on the totality of the
circumstances in the view of a trained law enforcement officer. Sharp, 305 Kan. 1081.

We find that under the totality of circumstances, reasonable suspicion supported
Deputy Fisher's extension of the original traffic stop into a DUI investigation. Deputy
Fisher articulated a reasonable suspicion of criminal activity which included observing an
open box of Busch Light in Knox's back seat, an open beer at his feet, an odor of alcohol,
and Knox's admission to drinking four or five beers that evening. Kansas courts have
acknowledged that each of these factors may be properly considered within a totality of
the circumstances analysis. These facts, considered in sum, demonstrate reasonable
suspicion that Knox had committed the crime of DUI which allowed Deputy Fisher to
lawfully extend the original traffic stop into a DUI investigation. The district court did
not err in denying Knox's motion to suppress.

Affirmed.
