Defendant-Appellant Guadalupe Quin-tana-Garcia (“Defendant”) entered a con *1268 ditional guilty plea to a three-count indictment charging her with conspiring to possess with intent to distribute less than 50 kilograms of marijuana, in violation of 21 U.S.C. § 846; possession with intent to distribute less than 50 kilograms of marijuana, in violation of 21 U.S.C. § 841(a)(1) and (b)(1)(d) and 18 U.S.C. § 2; and possession of cocaine, in violation of 21 U.S.C. § 844. She reserved her right to appeal the district court’s denial of her motion to suppress evidence obtained as the result of a Border Patrol Agent’s allegedly illegal stop of the vehicle in which she was traveling. We take jurisdiction pursuant to 28 U.S.C. § 1291 and, for the reasons that follow, AFFIRM the district court’s denial of Defendant’s motion to suppress.
I. BACKGROUND 1
On the morning of June 30, 2001, Border Patrol Agent Rudy Sanchez parked his marked patrol vehicle on the side of Highway 26, a road that carries mostly local traffic between the towns of Deming and Hatch in southern New Mexico, approximately 50 to 60 miles from the Mexican border. There are three permanent Border Patrol checkpoints in southern New Mexico but none on Highway 26, which is known as a “back door” for smugglers wanting to avoid the checkpoints.
At approximately 11:45 a.m., Agent Sanchez saw a large, gray Chevy Suburban traveling north on Highway 26, away from the Mexican border. Having previously arrested smugglers of both illegal aliens and drugs who drove sport utility vehicles, he knew that smugglers tended to prefer large vehicles because they can carry more cargo. The Suburban also had tinted windows, which is another feature preferred by smugglers, and Mexican license plates, which was somewhat unusual as most of the traffic on Highway 26 was local traffic used by New Mexico residents in the area. Agent Sanchez learned from a radio dispatcher that the car had passed through a border checkpoint at the Mexican border approximately two to three hours earlier. Agent Sanchez also thought it significant, for two reasons, that the car was approaching his area around lunchtime. First, one week earlier he had apprehended a vehicle carrying illegal aliens around lunchtime. Second, Border Patrol agents had learned through interviews and investigation that smugglers knew the agents’ schedules and would often try to slip past them at lunch or during shift changes.
Agent Sanchez’s vehicle was not equipped with a radar device, but he estimated that ‘the car was traveling about 75 miles per hour, 10 miles per hour above the posted speed limit. The district court found that in Agent Sanchez’s experience, “smugglers move [as] quickly as possible through the border area to make certain that their presence for any protracted period doesn’t expose them to interception.” As the car approached (and presumably saw) Agent Sanchez’s vehicle, it slowed “significantly,” which indicated to Agent Sanchez that the driver did not want to be “detected or be noticed if they were transporting illegal aliens.”
Based on these observations, Agent Sanchez suspected that the driver of the Suburban might be smuggling illegal aliens. He pulled onto the highway and began to follow the Suburban, but he did not at that *1269 time turn on Ms flashing lights or his siren. As he followed it, the Suburban slowed again, this time to approximately 45-50 miles per hour. It soon slowed even further and pulled over to the right side of the road, still moving. Agent Sanchez was worried, based on experience, that the occupants of the Suburban might attempt a “bailout,” which is an escape tactic in which the occupants jump from a slowly moving car and run in different directions to avoid capture. As the Suburban pulled to the side of the road, Agent Sanchez turned on his patrol vehicle’s flashing lights. Unlike most cars, the Suburban did not stop immediately; rather, it continued moving for approximately another minute before it stopped.
Agent Sanchez exited his vehicle and approached the Suburban. He spoke first to the driver, Leahmanda Barnes, and asked her if she was a United States citizen. She said that she was and produced her driver’s license. He then asked the person sitting in the passenger’s seat, Defendant, if she was a U.S. citizen. Defendant produced her border crossing card, which showed that she was a Mexican national. A border crossing card allows the holder to cross the Mexico/U.S. border as long as she stays within 25 miles of the border; to go farther, a special permit is required. 2 Agent Sanchez then asked Barnes if she owned the vehicle, and Barnes told him that Defendant owned it. Agent Sanchez asked Defendant if that was correct, and Defendant indicated that she did not speak English.
Agent Sanchez switched to Spanish and continued questioning Defendant about her ownership of the Suburban. As he did so, he “smelled a strong odor” that he “recognized as silicone sealant.” Agent Sanchez said that based on his experience, “silicone sealant, along with bondo, are the two most commonly used materials to secrete [sic] narcotics[,] to seal trap doors, to seal compartments, and it aroused [his] suspicion that this vehicle might be carrying narcotics.” Based on this suspicion, Agent Sanchez asked Defendant for permission to have his K9 police dog inspect the Suburban. Defendant consented.
During the inspection, the police dog alerted to the Suburban’s gas tank. Agent Sanchez noticed immediately that the bolts attaching the gas tank to the vehicle had been tampered with: “they had shiny tool marks on them, and the hose, the filler neck hose, the camp, was left loose, it was just dangling there, it had not even been tightened down.” When Agent Sanchez used a fiberoptic scope to inspect the gas tank, he saw fresh welding marks inside it, which indicated to him that something was hidden in the tank. He then asked Defendant and Barnes if they would follow him to a nearby Border Patrol checkpoint where he could further examine the tank. They agreed to do so. At the checkpoint, the gas tank was opened and twenty-one bundles of marijuana, weighing approximately ninety-three pounds, were found inside. Defendant also had some cocaine in her purse.
Defendant moved to suppress the evidence obtained as a result of the stop on the ground that Agent Sanchez lacked the required reasonable suspicion to conduct *1270 the stop. After a hearing, the district court denied the motion. Defendant was later sentenced to, inter alia, 330 days’ imprisonment and two years’ supervised release.
II. DISCUSSION
In reviewing a district court’s denial of a motion to suppress, we accept the district court’s factual findings unless they are clearly erroneous.
United States v. Gandara-Salinas,
“The Fourth Amendment prohibits ‘unreasonable searches and seizures’ by the Government, and its protections extend to brief investigatory stops of persons or vehicles that fall short of traditional arrest.”
United States v. Arvizu,
The Supreme Court has emphasized that, in determining whether an investigatory stop is supported by reasonable suspicion, courts must “ ‘look at the totality of the circumstances’ of each case to see whether the detaining officer has a ‘particularized and objective basis’ for suspecting legal wrongdoing.”
Id.
The evaluation is made from the perspective of the reasonable
officer,
not the reasonable
person.
Officers must be permitted “to draw on their own experience and specialized training to make inferences from and deductions about the cumulative information available to them that ‘might well elude an untrained person.’ ”
Id.
(quoting
United States v. Cortez,
In determining whether a stop in a border area is supported by reasonable suspicion, the following factors are relevant;
(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.
Gandara-Salinas,
In the instant case, the district court, after hearing testimony and making factual findings, held that “the totality of the circumstances of which Agent Sanchez was aware at the time he stopped the vehiele[ ] gave him a reasonable suspicion to justify a stop” under Arvizu. 4 , An examination of the eight Brignoni-Ponce factors — seven of which are present in this case — makes clear that the district court’s decision was correct. We address each factor in turn. 5
With respect to the first
BrignoniPonce
factor — the characteristics of the area in which the vehicle was encountered,
The second
Brignoni-Ponce
factor considers the proximity to the border of the area where the stop was made.
The third
Brignoni-Ponce
factor looks to the usual traffic patterns on the road where the stop was made.
The fourth
Brignoni-Ponce
factor- — the agent’s previous experience with alien traffic,
The fifth
Brignoni-Ponce
factor considers information about recent illegal border crossings in the area where the stop was made.
The sixth
Brignoni-Ponce
factor addresses the driver’s behavior prior to the stop.
The seventh
Brignoni-Ponce
factor considers the features of the vehicle, such as its size and capacity for carrying contraband.
The eighth and final
Brignoni-Ponce
factor considers whether the vehicle appears to be heavily loaded.
Our review of the district court’s factual findings and of the eight
Brignoni-Ponce
factors leads us to conclude that under the totality of the circumstances, Agent Sanchez’s stop of Defendant’s vehicle was supported by reasonable suspicion. While “ ‘[a]ny one of these factors is not by itself proof of any illegal conduct and is quite consistent with innocent travel[,] ... taken together they amount to reasonable suspicion.’ ”
United States v. Neufeld-Neufeld,
Notes
. The facts in this section are taken from the district court's factual findings at the hearing on Defendant's motion to suppress and from testimony given at that hearing.
. The parties dispute whether Defendant also produced at that time an 1-94 permit, which was necessary for her to have legally traveled more than 25 miles beyond the border. Because the motion to suppress focused on Agent Sanchez’s initial reasons for stopping the Suburban, however, that dispute is not relevant to our disposition of this case and we therefore need not resolve it.
.In
Arvizu,
the Court unanimously reversed the Ninth Circuit's decision granting the defendant's motion to suppress based on an allegedly illegal stop. The Court considered the following facts — any one of which might be considered innocent standing alone — as supporting the Border Patrol agent's finding of reasonable suspicion when considered in the aggregate: 1) the stop occurred in a remote part of rural southeastern Arizona, a region known by law enforcement to be frequented by drug smugglers; 2) the defendant was driving a minivan, a vehicle known to be used by drug smugglers; 3) the minivan slowed considerably when it saw the Border Patrol agent's car on the side of the road; 4) as he passed, the driver of the minivan (the defendant) seemed stiff and his posture rigid, and he did not look at the agent, as if trying to pretend the agent were not there; 5) the time of day indicated that the defendant intended to pass through the area during the agents' shift change; 6) another Border Patrol agent had apprehended a minivan using the same route several weeks before and saw the occupants throwing bundles of marijuana out the door; 7) despite the fact that two adults and three children were in the minivan, which would suggest a family outing, the minivan had turned away from known recreational areas; 8) the children sitting in the back seat had their knees propped up unusually high, as if they were sitting on something; 9) when the Border Patrol agent pulled behind the minivan, the children, while still facing forward, began to wave at the agent in an abnormal way, as if they were being told to do so; 10) the driver signaled as if he were going to turn off onto the last road that could be used to avoid a nearby checkpoint, but then turned his signal off and then back on again as if he could not decide what to do; moreover, that road was rougher than the one he was currently on and used mostly by four-wheel-drive vehicles; and 11) a registration check of the car showed that it was registered to an address only four blocks north of the border and well known for alien- and drug-smuggling.
Arvizu,
. On appeal, Defendant challenges several of the district court’s factual findings. Having reviewed those challenges as well as the record in its entirety, we find nothing to persuade us that any of the district court's findings were clearly erroneous. For the sake of brevity, we decline to address Defendant's challenges individually.
. We pause at the outset to emphasize that even though Agent Sanchez ultimately found drugs in Defendant’s vehicle, the issue before us is whether Agent Sanchez's stop was justified by a reasonable suspicion that he would find
illegal aliens,
which was his articulated reason for initially stopping Defendant's vehicle.
See United States v. Williams,
. We also find it instructive, although not dispositive, that federal law permits Border Patrol agents to make warrantless stops within a “reasonable distance” from the border. 8 U.S.C. § 1357(a)(3). "Reasonable distance” is defined by a federal regulation as, inter alia, 100 miles from the border. 8 C.F.R. § 287.1(a)(2).
