Before WIENER and STEWART, Circuit Judges, and LITTLE, District Judge.*

LITTLE, District Judge:**

Appellant challenges the legitimacy of the investigative stop that led to his arrest for, and

subsequent plea of guilty to, the charge of illegally smuggling aliens into the United States. For the
2

following reasons, we affirm the district court’s finding that the stop was supported by reasonable

suspicion derived from articulable facts and their attendant rational inferences.

FACTUAL AND PROCEDURAL BACKGROUND

On 26 October 1998, at approximately 10:15p.m., Border PatrolAgents Edward J. Kelly and

Paul Backor were on roving patrol in a marked sedan, driving southbound on F.M. 2520. These

agents were on a staggered shift of 4 p.m. to 12 a.m. as the Border Patrol had determined that

smugglers of aliens were taking advantage of the confusion engendered by the standard shift change

at 10 p.m. by perfoming the bulk of their activity at that time. Traffic was light on F.M. 2520 at that

time of night. From a distance of about a quarter-mile, the agents noticed a van turn north on F.M.

2520 from Highway 281. The van appeared to be proceeding east on Highway 281 before turning

on to F.M. 2520. At that junction, Highway 281 is a little less than a mile from the Rio Grande. This

intersection was known by the Border Patrol and these part icular agents to be especially rife with

smuggling of illegal aliens, with transport vehicles picking up the aliens at abandoned houses nearby.

At least twenty times within the preceding year, Agent Kelly had apprehended illegal aliens in the

immediate area fromwhich the van came. The agents slowed and pulled over to the shoulder, hoping

to get a good look at the van as it passed by. The van approached slowly. Illuminated only by the

low beam headlights of the Border Patrol sedan, the van appeared to be a passenger van of older

vintage and riding very low in the rear. The agents then turned to follow the van, tracking it at a

distance of about six car lengths. The headlights of the sedan were situated much lower than the

windows of the passenger van, so the agents decided to rely on illumination provided by oncoming

vehicles proceeding southbound. Over the course of three miles, a few cars passed and the
3

illumination provided thereby indicated that the van had only two people in it. The cause of the

excessive weight could not be determined, but there appeared to be condensation on the windows.

Asthe weather that evening was not conducive to causing condensation on the windows, the Agents

concluded that the condensation would be an indication that there were many more than two people

riding in the van. The agents then tried to get closer to the van so they could run a vehicle

registration and stolen vehicle check. The van however had no license tags. The agents then passed

the van and stopped at an intersection about a mile down the road. The agents had ten seconds to

examine the van as it passed by. Unfortunately, there was no back lighting so they could not see

through the side windows. They confirmed that the van was riding in an obviously overloaded

condition, a condition confirmed by the fact that the back right wheel was obscured. The agents then

pulled in behind of the van and shortly thereafter stopped the van. The condensation on the windows

and the overloaded condition of the van could reasonably be caused by human cargo in excess of the

two known occupants of the van. 

The agents approached the van brandishing their flashlights. Agent Kelly shined his flashlight

through a rear window and saw numerous bodiesstacked on top of each other. The occupants were

lying below the plane of the window. The driver of the van--the appellant--willingly surrendered the

keysto the van and was arrested. The appellant made no effort to flee or otherwise evade the agents’

commands. It was then determined that there were nineteen illegal aliens stacked like cord wood on

top of each other in the van. 

On 4 January 1999, the district court entertained a motion to suppress any evidence gained

from the investigative stop. The district court denied the motion, finding the requisite reasonable
4

suspicion based on the following articulable facts: (1) the proximity to the border; (2) the agent had

personal knowledge of heavy alien traffic in the area; (3) the appearance of the vehicle, particularly

the fact that it was over loaded; (4) there appeared to be only two occupantsin the vehicle; (5) closer

inspection by the agents did not dissuade them of their suspicion. The appellant then entered a

conditional plea of guilty. Appellant was sentenced on 8 April 1999 to a term of imprisonment of

eight months, three years supervised release, and 250 hours of community service. Appellant filed

a timely notice of appeal.

STANDARD OF REVIEW

Appellant does not challenge Agent Kelly’s recitation of the facts but rather maintains that

those facts do not support an investigative stop. We review the district court’s legal conclusion de

novo. See United States v. Aldaco, 168 F.3d 148, 149-50 (5th Cir. 1999). The evidence is viewed

in the light most favorable to the prevailing party; in this case, the government. See United States v.

Gonzalez, 190 F.3d 668, 671 (5th Cir. 1999).

DISCUSSION

Investigative stops bythe border patrolmust complywith the stricturesimposed bythe Fourth

Amendment. See United States v. Brignoni-Ponce, 422 U.S. 873, 878 (1975) (“The Fourth

Amendment appliesto allseizures ofthe person, including seizuresthat involve only a brief detention

short of traditional arrest.”); United States v. Nichols, 142 F.3d 857, (5th Cir. 1998) (“We are, of

course, bound by Supreme Court precedent on the matter, but our reassessment, in light of current

events, of the competing interests at stake in the determination of reasonable suspicion bolsters the
5

continued vitality of the Supreme Court's mandate in Brignoni- Ponce.”). “Border patrol ‘officers

on roving patrol may stop vehicles only if they are aware of specific articulable facts, together with

rational inferencesfromthose facts, that reasonablywarrant suspicion that the vehicles contain aliens

who may be illegally in the country.’” United States v. Orozco, 191 F.3d 578, 581 (5th Cir. 1999)

(quoting United States v. Brignoni-Ponce, 422 U.S. 873, 884 (1975)). “In applying the

Brignoni-Ponce standard, this Court has recognized that the Supreme Court underpinned the

standard with a balancing test; the public interest in addressing the continuing problems of alien and

drug smuggling must be weighed against the private interest of an individual to be let alone in

exercising his or her liberty.” U.S. v. Lopez-Valdez, 178 F.3d 282, 286 (5thCir. 1999). The following

factors are a helpful guide in the reasonable suspicion calculus:

(1) proximity of the area to the border; 

(2) known characteristics of the area; 

(3) usual traffic patterns on that road; 

(4) agent's previous experience in detecting illegal activity; 

(5) information about recent illegal trafficking in aliens or narcotics in the area; 

(6) particular aspects or characteristics of the vehicle; 

(7) behavior of the driver; and 

(8) the number, appearance, and behavior of the passengers. 

Orozco, 191 F.3d at 581; see also Brignoni-Ponce, 422 U.S. at 884-85. “No single factor is

determinative; rather, this Court examines each case based on ‘the totality of the circumstances
1Appellant argues that the fact that the van was riding unusually low in the rear hasbeen accorded low weight by this court. See

United States v. Melendez-Gonzalez, 727 F.2d 407, 412 (5th Cir. 1984); United States v. Orona-Sanchez, 648 F.2d 1039, 1042 (5th Cir.

1981); United States v. Pacheco, 617 F.2d 84, 86 (5th Cir. 1980). Central to the resolution of each of these cases is the fact, however, that

the vehicles in question wereapprehendedat least fifty miles from the border. See Melendez-Gonzalez, 727 F.2d at 409 (60 miles); OronaSanchez, 648F.2d at 1040(50 miles);Pacheco, 617F.2d at 86 (85 miles). The van in this case was apprehended four miles from the border,

having been first sighted one mile from the border.

2Appellant argues that the agents relied on a mistaken belief that there was condensation on the windows. Appellant points to

United States v. Rodriguez-Rivas, 151 F.3d 377, 381 (5th Cir. 1998), as authority for the propostion that mistaken perceptions are not given

great weight. In that case, theagents thought that the driver was slouching to avoid identification; in fact, he was 5'7". This Court however

will credit mistaken perceptions when they are reasonable in light of the circumstances. “It is apparent that in order to satisfy the

"reasonableness"requirement of theFourthAmendment, what is generallydemanded of the many factual determinations that must regularly

be made by agents of the government ... is not that they always be correct, but that they always be reasonable. ... ‘Because many situations

which confront officers in the courseof executing their duties are more or less ambiguous, room must be allowed for somemistakes on their

part. But the mistakes must be those of reasonable men, acting on facts leading sensibly to their conclusions of probability.’” Illinois v.

Rodriguez, 497 U.S. 177, 185-86 (1990) (quoting Brinegar v. United States, 338 U.S. 160, 176 (1949)); United States v. Morales, 191 F.3d

602, 606 (“Theprocess does not deal with hard certainties,but with probabilities. Long beforethe law of probabilities was articulated as such,

practicalpeopleformulatedcertaincommonsenseconclusions about humanbehavior; jurors as factfinders arepermittedtodothesame--and

so are law enforcement officers.”). Agent Kelly testified that the windows were translucent and that windows are not ordinarily spray painted

6

known to the agent, and the agent's experience in evaluating such circumstances.’” United States v.

Chavez-Chavez, 205 F.3d 145, 148 (5thCir. 2000) (quoting United States v. Inocencio, 40 F.3d 716,

722 (5th Cir.1984) (internal quotation marks and citation omitted)).

The above factors counsel a finding of reasonable suspicion in this case. The van was

travelling in a northern direction in an area in close proximity to the border and that area was known

by the agents to be frequented by transporters of illegal aliens. See Aldaco, 168 F.3d at 150 (“This

Circuit has recognized that the proximity of a stop to the border is a paramount factor. ... [In

addition, it] is well established that a road's reputation as a smuggling route adds to the

reasonableness of the agents' suspicion.”). In stark contrast with its riding very low in the rear, the

van appeared to have only two occupants.1 See United States v. Cardona, 955 F.2d 976 (5th Cir.),

reh'g denied, 961 F.2d 215 (5th Cir.), cert. denied, 506 U.S. 942 (1992) (finding reasonable

suspicion where “[the vehicle] was riding considerably low to the ground despite the fact that only

two persons were visible inside it.”). The agents also believed that the van had condensation on its

windows.2See United States v. Garcia, 732 F.2d 1221, 1225 n.2 (5th Cir. 1984) (finding that
black. Given what the agents knew (and should have known) at the time of the stop, their mistaken perception was reasonable.

7

condensation on windows led to reasonable suspicion that “the [heavy] cargo was breathing.”).

These facts, taken together, more than amount to the reasonable suspicion necessary to make an

investigative stop. It is important to note, in this respect, that the agents confirmed their observations

from a variety of angles. This salutory behavior on the part of the agents is exactly what the Fourth

Amendment encourages. See Terry v. Ohio, 392 U.S. 1, 22 (1968) (distinguishing reasonable

suspicion from “inarticulate hunches.”).

For the foregoing reasons, we AFFIRM the district court’s denial of the motion to suppress

and the appellant’s conviction and sentence.
