                            ORDER AND JUDGMENT *


Before TACHA, Chief Circuit Judge, EBEL, and BRISCOE, Circuit Judges.




      After examining the briefs and the appellate record, this three-judge panel

has determined unanimously that oral argument would not be of material

assistance in the determination of this appeal. See Fed. R. App. P. 34(a)(2); 10th

Cir. R. 34.1(G). The case is therefore ordered submitted without oral argument.

      Defendant-Appellant, James Christopher Landshof, pled guilty to one count

of possession of marijuana with intent to distribute, in violation of 21 U.S.C.

                                    I. Discussion 2

      A.     Standard of Review

      We review a district court's denial of a motion to suppress in a light most

favorable to the government, considering the totality of the circumstances. U.S. v.

Long, 

, 1307 (10th Cir. 1999) (citations omitted). “We accept the

district court's factual findings unless those findings are clearly erroneous.” 

The ultimate determination of reasonableness under the

Fourth Amendment, however, is a question of law, which we review de novo. 

      1. Overview of Applicable Fourth Amendment Law

      In reviewing the constitutionality of traffic stops under the Fourth



      1
       United States v. Landshof, No. 02-40004-01-SAC , 

(D.
Kan. April 23, 2002) (order denying defendant’s motion to suppress).
      2
        The events in this case arise from a traffic stop by Kansas Highway Patrol
Trooper Joseph Ziegler on February 13, 2001, which led to a search of Landshof’s
vehicle and the discovery of 236 pounds of marijuana. The facts in this case are
few and, for the most part, uncontested. As the district court’s order sets forth
the relevant facts in ample detail, see United States v. Landshof, No. 02-40004-01-
SAC , 

(D. Kan. April 23, 2002), we do not recount them in full
here.

Amendment, we conduct a two-step inquiry. First, we must determine “whether

the officer’s action was justified at its inception.” United States v. Gonzalez-

Lerma, 

, 1483 (10th Cir. 1994). Second, we must consider “whether

the action was reasonably related in scope to the circumstances that first justified

the interference.” 

or questioning, unrelated to the traffic

stop, is only permissible (1) where the officer has “objectively reasonable and

articulable suspicion that illegal activity has occurred or is occurring,” or (2) “ if

the initial detention has become a consensual encounter.” 

      2. Whether Trooper Ziegler’s Detention of Landshof was Reasonable at Its

             Inception.

      “[A] detaining officer must have    an objectively reasonable articulable

suspicion that a traffic violation has occurred or is occurring before stopping [an]

automobile.” United States v. Soto, 

, 1554 (10th Cir. 1993)

(citation omitted). In this case, Trooper Ziegler observed Landshof’s vehicle

weave within the traffic lane and cross approximately six inches over the right-

side fog line. Further, according to Trooper Ziegler’s testimony, Landshof was

operating his vehicle under optimal road, weather, and traffic conditions. Finally,

Trooper Ziegler noticed that Landshof appeared tired. Based on these

observations, Trooper Ziegler had objectively reasonable, articulable suspicion




                                          -3-
that Landshof was operating his vehicle in violation of Kan. Stat. Ann. § 8-1522. 3

Compare United States v. Ozbirn, 

, 1198 (10th Cir. 1999)

(“[officer] had probable cause to stop [defendant] after he saw the motor home

drift onto the shoulder twice within a quarter mile under optimal road, weather

and traffic conditions”), with United States v. Gregory, 

, 978 (10th

Cir. 1996) (finding no reasonable suspicion because an “isolated incident of a

vehicle crossing into the emergency lane of a roadway . . . . [where] road was

winding, the terrain mountainous and the weather condition was windy” does not

constitute a violation of the relevant Utah traffic law) (citation omitted).

Alternatively, at a minimum, Trooper Ziegler’s observations were “sufficient to

create a reasonable suspicion that . . . [Landshof] might be sleepy or impaired,

and could present a risk of harm to himself and others.” 

(citing cases).

      Based on the above, we conclude that Trooper Ziegler’s initial stop of

Landshof was reasonable under the Fourth Amendment.        4
                                                               See 

        Under Kan. Stat. Ann. § 8-1522, “[w]henever any roadway has been
divided into two (2) or more clearly marked lanes for traffic, . . . . vehicle[s] shall
be driven as nearly as practicable entirely within a single lane . . .”
      4
        We reject Landshof’s invitation to revisit the question of whether
probable cause, rather than reasonable suspicion, must support a routine traffic
stop. As Landshof acknowledges, we rejected an identical argument in United
States v. Callarman, 

(10th Cir. 2001).

1198-99.

      3. Whether Trooper Ziegler’s Actions Were Reasonably Related in Scope to

             the Circumstances That Initially Justified the Detention.

      “During a routine traffic stop, the detaining officer may request a driver’s

license and vehicle registration, run a computer check on the car and driver, and

issue a citation.” 

(citations omitted). In addition, the

detaining officer may question the vehicle’s occupants regarding their travel

plans. United States v. Williams, 

, 1267 (10th Cir. 2001).

      Once an officer has issued a citation in a traffic stop,   “‘[i]f the driver

produces a valid license and proof of right to operate the vehicle, the officer must

allow him to continue on his way without delay for further questioning.’” 

(citing United States v. Pena, 

, 1514 (10th Cir.

1990)). Further detention, unrelated to the traffic stop, is permissible in only two

instances: (1) if the officer has “objectively reasonable and articulable suspicion

that illegal activity has occurred or is occurring”; or (2) “if the initial detention

has become a consensual encounter.” 

(citations

omitted).

      In reviewing reasonable-suspicion determinations, we must consider the

“‘totality of the circumstances ’ of each case to see whether the detaining officer

ha[d] a ‘particularized and objective basis’ for suspecting legal wrongdoing.”

                                            -5-
United States v. Arvizu , 

, 273 (2002) (emphasis added and citations

omitted). Reasonable suspicion may exist, even if “each of the[] factors alone is

susceptible of innocent explanation.”      

In other words, “[a]

determination that reasonable suspicion exists . . . need not rule out the possibility

of innocent conduct.”      

case, Trooper Ziegler possessed reasonable, articulable suspicion of

criminal activity sufficient to justify the fifteen-minute detention of Landshof’s

automobile,   5
                  based on numerous observations he made during the routine traffic

stop. First, Trooper Ziegler testified that Landshof appeared extremely nervous

during the encounter, and this nervousness did not diminish after Ziegler

informed Landshof that he would not issue a citation.        See United States v. Kopp   ,

, 1454 (10th Cir. 1995) (holding defendant’s nervousness, in part,

presented officer with reasonable, articulable suspicion of criminal activity);     Soto ,

988 F.2d at 1556 (same).     6
                                 Second, Trooper Ziegler detected the odor of an air



       5
        We have previously held that reasonable, articulable suspicion can justify
the limited detention of an automobile. See United States v. Brown, 

, 1226 (10th Cir. 1994) (“[A]ny ‘investigative detention’ of the [automobile]
was based on reasonable suspicion and ‘was properly limited in scope,’ only
lasting about 30 minutes at the most.”).

       Conversely, we have held that an officer may not rely upon his “sixth
       6

sense” or that there was “tension in the air” as a reasonable, articulable suspicion
of criminal activity. See United States v. Fernandez, 

, 881 (10th Cir.
1994).

                                             -6-
freshener, which he knew was often used to mask the odor of marijuana, based on

his law-enforcement training.     See , e.g. , United States v. Villa-Chaparro    , 

, 802 (10th Cir. 1997) (“Although the scent of a masking agent alone is

insufficient to establish reasonable suspicion, we have repeatedly held that air

freshener coupled with other indicia of criminal activity supports a reasonable

brief inquiry”) (internal quotation marks and quotation omitted);          United States v.

Stone , 

, 362 (10th Cir. 1989) (finding reasonable suspicion based, in

part, on odor of Patchouli oil). Third, Trooper Ziegler testified that Landshof’s

unusual travel plan—flying from New York to St. Louis, renting a car, and then

driving to Denver 7—coupled with the implausibility of carrying his three large

suit cases through an airport, further heightened his suspicions.      8
                                                                           See 

(finding reasonable suspicion based, in part, on implausibility of

defendant’s explanation of his travel plans and purpose). Fourth, Landshof told

Trooper Ziegler that he was a computer salesman, a statement that was

inconsistent with certain aspects of Landshof’s physical appearance.             Cf. United


       7
        Landshof notes that “his stop in St. Louis could have been to see another
client” or he “may simply have been interested in seeing the Missouri and Kansas
landscape.” Landshof did not, however, offer any such explanation to Trooper
Ziegler in response to his inquiry.

       Trooper Ziegler testified as follows: “I posed him with a couple
       8

questions; why didn’t you fly straight into Denver, why do you have these big
cases. He didn’t really have any answers for me and that kind of added a little bit
more to it . . . .”

States v. Turner , 

, 959 (10th Cir. 1991) (    “Defendant claimed that he

was an auto mechanic, but the officer observed that his hands were well-

manicured and did not appear to be in the condition of someone who works as an

auto mechanic”). Fifth, Trooper Ziegler observed that the back of Landshof’s

vehicle appeared weighted down, sagging some three to four inches.            9
                                                                                  See , e.g. ,

United States v. Sharpe , 

, 683 n.4 (1985) (finding reasonable

suspicion of drug-trafficking based, in part, on the fact that “pickup truck

appeared to be heavily loaded”);     United States v. Summerville     , 

, 395

(5th Cir. 1973) (finding probable cause based, in part, on fact that “vehicle was

riding low ‘as if it were weighted down’”).

                                      II. Conclusion

       In sum, Landshof’s argument employs the same “divide and conquer”

methodology recently rejected by the Supreme Court in          United States v. Arvizu ,

, 274 (2002). In light of the totality of the circumstances, we cannot

say that the district court committed reversible error in concluding that Trooper

Ziegler had reasonable, articulable suspicion of criminal activity.      10
                                                                              Accordingly,


       9
        Landshof argues that the district court erred in accepting Trooper
Ziegler’s testimony on this point. Although we disagree, we note that even if
Landshof is correct, the remaining factors would still support a finding of
reasonable suspicion.
       10
            Although Landshof does not challenge the use of the drug dog or the
                                                                       (continued...)

AFFIRM Landshof’s conviction under 21 U.S.C. § 841(a)(1).
