I
On the morning of August 30, 2001, United States Border Patrol Agent
Collier observed Mr. Gandara driving north on U.S. Highway 54 between
Alamogordo, New Mexico and the Mexican border in a pickup truck with
Chihuahua, Mexico license plates. Although that stretch of Highway 54 usually
has a border control checkpoint, the fixed checkpoint had been torn down earlier
in the summer for road construction. The absence of the checkpoint led to an
increased use of the highway for smuggling. The agent followed Mr. Gandara for
fifteen to twenty minutes, both on the highway and through town, during which
time he made several observations that raised his suspicion about possible illegal
behavior by Mr. Gandara. Most noteworthy among those observations were that
the truck had recently crossed the border, the truck had foreign license plates, the
drug checkpoint was temporarily closed resulting in an increase in drug traffic,
and the spare tire appeared much larger than the other truck tires and much
-2-
cleaner than the rest of the truck. After following Mr. Gandara through town,
Agent Collier stopped the truck. Mr. Gandara consented to a canine inspection.
The dog alerted to the gas tank of the truck. Agent Collier found approximately
150 pounds of marijuana in the gas tank and spare tire, which turned out in fact to
be much larger than the truck’s other tires.
Mr. Gandara moved to suppress this evidence on the ground that Agent
Collier did not have the requisite reasonable suspicion to conduct an immigration
stop. The district court granted the motion. United States v. Gandara-Salinas,
215 F.Supp.2d 1207 (D.N.M. 2002).
II
The ultimate determination of reasonableness under the Fourth Amendment
is a conclusion of law that we review de novo. See United States v. De La Cruz-
Tapia, 162 F.3d 1275, 1277 (10th Cir. 1998). We view the evidence in the light
most favorable to the prevailing party, and we accept the district court’s findings
of fact unless they are clearly erroneous. See id. at 1277-78. After reviewing the
record, we are persuaded the court misapplied certain legal standards and
committed clear error in assessing the testimony of Agent Collier.
The district court correctly recited the applicable legal standards. The
Fourth Amendment requires a finding of reasonable suspicion that criminal
-3-
activity may be afoot in order to conduct roving border patrol stops. See United
States v. Arvizu, 534 U.S. 266, 273 (2002) (quotations and citations omitted). See
also United States v. Brignoni-Ponce, 422 U.S. 873 (1975). “Although an
officer’s reliance on a mere hunch is insufficient to justify a stop, the likelihood
of criminal activity need not rise to the level required for probable cause, and it
falls considerably short of satisfying a preponderance of the evidence standard.”
Arvizu, 534 U.S. at 274 (quotations and citations omitted) (emphasis added).
Border patrol agents may thus stop vehicles “if they are aware of specific
articulable facts, together with rational inferences from those facts, that
reasonably warrant suspicion” of criminal activity. United States v. Monsisvais,
907 F.2d 987, 989-90 (1990) (quoting Brignoni-Ponce, 422 U.S. at 884).
The following factors are relevant in determining whether an immigration
stop is supported by reasonable suspicion:
(1) characteristics of the area in which the vehicle is encountered; (2)
the proximity of the area to the border; (3) the usual patterns of
traffic on the particular road; (4) the previous experience of the agent
with alien traffic; (5) information about recent illegal border
crossings in the area; (6) the driver’s behavior, including any obvious
attempts to evade officers; (7) aspects of the vehicle, such as a
station wagon with concealed compartments; and (8) the appearance
that the vehicle is heavily loaded.
Monsisvais, 907 F.2d at 990 (citing Brignoni-Ponce, 422 U.S. at 884-85). A law
enforcement officer may assess these factors in light of his experience and
specialized training, see Brignoni-Ponce, 422 U.S. at 885, and a court should
-4-
accord deference to an officer’s ability to distinguish between innocent and
suspicious actions, see De La Cruz-Tapia, 162 F.3d at 1277. Guided by these
factors, the ultimate assessment of reasonable suspicion depends on the totality of
the circumstances. See id. In making that determination, a court may not
evaluate and reject each factor in isolation. See Arvizu, 534 U.S. at 274-75.
In assessing the totality of the circumstances in this case, the district court
appears to have engaged in the “sort of divide-and-conquer analysis” the Supreme
Court disapproved in Arvizu. See id. at 274. The court looked at each of Agent
Collier’s observations and believed each was, by itself, readily susceptible of an
innocent explanation. More importantly, the district court failed to accord
deference to the agent’s ability to “draw on [his] own experience and specialized
training to make inferences from and deductions about the cumulative information
available to [him] that might well elude an untrained person.” Id. at 273
(quotation and citation omitted). “A determination that reasonable suspicion
exists . . . need not rule out the possibility of innocent conduct.” Id. at 277.
The district court dismissed several of the Brignoni-Ponce factors – the
recent border crossing, the foreign license plates, the temporary closure of the
border checkpoint, and the proximity to the border – as not indicative of criminal
activity because they could be susceptible of an innocent explanation. Gandara-
Salinas, 215 F.Supp.2d at 1210-11. Because each of these factors is explicitly
-5-
listed as an appropriate consideration in the Brignoni-Ponce analysis, however,
the Supreme Court has already determined they are considerations appropriate for
an agent to weigh. The district court also undervalued the ability of the agent to
assess these factors in light of all of his observations and his experience as a
border patrol agent.
In addition to these general errors in the district court’s approach, we have
a definite and firm conviction the court erred in assessing Agent Collier’s ability
to observe the irregular size of the spare tire on the truck. The court stated:
The Court finds it highly improbable that Agent Collier could have
made a reasonable comparison between Defendant’s spare tire and
the other four tires, including the tire treads, while traveling at
speeds up to 65 miles per hour. . . . Without any evidence to indicate
that Agent Collier could, indeed, make a reasonably accurate
estimate as to the size and cleanliness of the spare tire while driving
on a state highway, the Court does not find such testimony credible.
Id. at 1209-10. Our review of the record, however, persuades us there was ample
evidence to support the agent’s testimony. Agent Collier testified at length as to
his view of the tire – why he noticed it, what drew his attention, what indicated
the tire was oversized – and as to his extensive experience and knowledge relating
to tires in general from the years he worked on trucks as a mechanic. Aplt. App.
at 91-96. While the district court couched its finding as a credibility
determination, its statement in reference to the evidence presented indicates that
this was in reality a factual finding, and one that is not supported by the record.
-6-
For example, the court’s reference to the ability of the agent to observe the tire at
high speeds is simply incorrect. The agent followed the truck at varying speeds
for seven miles, including at slow speeds immediately behind the truck while
passing through a town. Id. at 91-92.
The size of the tire is of considerable importance in weighing the totality of
the circumstances to determine whether Agent Collier had reasonable suspicion of
criminal activity. The agent testified that his experience as a border patrol agent
included approximately 110-120 narcotics seizures, id. at 123, experience had
taught him spare tires are commonly used to smuggle narcotics, id. at 92-93, the
spare tire did not look like it fit properly underneath the vehicle, id. at 93, and he
closely examined the spare tire as he followed the vehicle, id. at 94-95. He also
testified that this particular section of highway is a common route for smuggling
undocumented immigrants and illegal drugs into the United States, id. at 77, he
had information the stretch of highway had seen an increase in smuggling while
the checkpoint was closed, id. at 84-85, he checked the truck’s Mexican license
plates and learned the vehicle had crossed the border the previous day, id. at 89-
90, and in his personal experience a high percentage of vehicles found to be
carrying narcotics have recently crossed the border, id. at 122.
Giving proper consideration to Agent Collier’s observations relating to the
factors discussed earlier and the evidence regarding the spare tire, we are
-7-
convinced the totality of the circumstances supports a finding of reasonable
suspicion of criminal activity justifying the stop. The evidence obtained in the
subsequent search of the truck should therefore not have been suppressed.
Accordingly, we REVERSE the district court’s suppression order and
REMAND the case for further proceedings.
