ORDER
Pending before the Court is Defendant’s Motion to Suppress (Dkt.# 14). The Government has filed a response thereto (Dkt.# 21). A hearing was held, and the Court heard testimony relating to the issues raised in the motion. After due consideration, the Court finds that Defendant’s motion should be denied for the following reasons.
I.
Facts 1
On April 25, 2005 at about 9:30 p.m., Defendant and four passengers who were illegal aliens were traveling northbound on IH-35 between Laredo and San Antonio in a 1994 White Infiniti. Border patrol agent Izaguirre was conducting roving patrol duties that night, and his vehicle was positioned at mile marker 74 on North IH 35 with its lights shining toward the interstate. As Defendant’s vehicle passed him, Agent Izaguirre observed a driver, a passenger in front, and a passenger in back. He drew no conclusions at that time, but *589 pulled out and “randomly” followed the vehicle as it proceeded northbound. As he followed the vehicle, Agent Izaguirre could not see clearly inside the car, so he used night vision goggles. He observed the driver and a front seat passenger, but not the back seat passenger that he had noticed earlier. He did, however, observe a “bulge” in the back seat, which is an indication that the passenger is attempting to hide. He also observed that the driver and front seat passenger refused to acknowledge his presence, which is a sign of nervousness. For these reasons, and based on his knowledge that alien smuggling during the night on North IH 35 is commonplace, the agent stopped Defendant’s vehicle at mile marker 84.
When the vehicle stopped, the front seat passenger opened his door and attempted to flee. The agent apprehended him, and asked why he was trying to flee. The passenger stated that he was an undocumented alien and was in the United States illegally. The agent then found three more Mexican citizens in the back seat, and Defendant in the driver’s seat. They were all taken into custody, and Defendant was advised of her Miranda rights. She confessed to transporting illegal aliens, and the aliens gave statements confirming her role in the smuggling scheme. Defendant has been indicted on two counts of transporting illegal aliens for profit.
In her motion, Defendant contends that Agent Izaguirre’s observations with the night vision goggles constituted an impermissible “search” in violation of the Fourth Amendment. Alternatively, she claims that the observations, if permissible, were not enough to establish reasonable suspicion and justify an investigatory stop.
II.
Legal analysis
The first issue is whether the agent’s observations with night vision goggles constituted a search under the Fourth Amendment. Defendant cites
Kyllo v. United States,
In the
Kyllo
case, law enforcement officials used a thermal imaging device to detect the presence of warm objects behind walls. Specifically, they used it to scan the defendant’s home to detect high intensity lights used in an indoor marijuana growing operation. The Court held that when the Government uses a device that is not in general public use to explore details of the interior of a home that would have previously been unknown without physical intrusion, the surveillance is a search and is presumptively unreasonable without a warrant.
Kyllo,
In making this determination, the Court finds two important distinguishing factors. First, the Supreme Court in
Kyllo
was very concerned with the sanctity of one’s home and the expectation of privacy therein. In this case, Defendant was driving down a heavily traveled interstate freeway in a vehicle open to public view. There is a clear distinction between the expectation of privacy behind the walls of one’s home and the expectation of privacy behind the windows of a vehicle.
Compare Kyllo,
121
*590
S.Ct. at 2045 (“In the home, our cases show, all details are intimate details, because the entire area is held safe from prying government eyes”)
with Cardwell v. Lewis,
The second important distinction in this case is the type of technology that was used to observe Defendant and her passengers. In
Kyllo,
the Supreme Court was persuaded by the fact that the thermal imaging device, which was not in “general public use,” penetrated walls to detect something that would otherwise be invisible, and it provided information regarding the interior of the home that could not otherwise have been obtained without “physical intrusion into a constitutionally protected area.”
Kyllo,
District courts addressing the use of night vision goggles since
Kyllo
have determined that there are significant technological differences between the thermal imaging device used in
Kyllo
and night vision goggles such as those used herein.
See e.g., United States v. Dellas,
For these reasons, the Court finds that Kyllo is clearly distinguishable, and the use of night vision goggles by Agent Izaguirre on April 25, 2005 to observe the inside of Defendant’s vehicle did not constitute a “search” in violation of the Fourth Amendment.
*591
The final issue is whether Agent Izaguirre was presented with sufficient facts to warrant a reasonable suspicion that the persons in the vehicle were engaging in criminal activity and to justify an investigatory stop. It is well settled that border patrol agents on roving patrol may stop vehicles if they are aware of specific articulable facts, together with rational inferences therefrom, that reasonably warrant suspicion that the vehicle contains illegal aliens.
United States v. Brignoni-Ponce,
At the hearing, Agent Izaguirre testified that he patrols the 37-100 mile marker area of 1-35 North between Laredo and San Antonio. He stated there is a total of 159 miles between Laredo and San Antonio, and he has made about 65 stops in the area. The farthest distance from the border that he has stopped a vehicle during roving patrol was at the 98 mile marker. The vehicle Defendant was driving was stopped at the 84 mile marker, which is about half way between Laredo and San Antonio. Agent Izaguirre stated that, based on his experience, illegal aliens often walk in a group until they get to Encinal, and then get transportation and travel up IH-35 to San Antonio.
During oral argument, defense counsel correctly noted that the vehicle was not in “close proximity” to the border, which is an important factor. The Fifth Circuit has held that a car traveling more than fifty miles from the border is usually viewed as being too far from the border to support an inference that its journey began there.
See United States v. Orozco,
Defendant does not dispute the evidence relating to the other factors, and the Court has carefully reviewed each of them, based on the facts herein. Agent Iza-guirre testified that he had been a border patrol agent for two years, and his principle duty was to detect and stop vehicles that were transporting illegal aliens. Agent Izaguirre testified, and noted in his investigative report, that IH-35 is a well-known and heavily used route for alien smuggling, and that he has personally handled a significant number of stops in that area. He was very familiar with the route and the manner in which aliens were smuggled on that route. On the night in *592 question, Agent Izaguirre observed a back seat passenger when the vehicle passed his stationary location. When following the vehicle, he could no longer see anyone in the back seat, but he did observe a “bulge” of some sort, which is indicative of an undocumented alien attempting to conceal himself. 3 He also observed that neither the driver nor front seat passenger were acknowledging his presence, and they appeared to be nervous. Agent Izaguirre also noted that illegal aliens are often smuggled during the night, and it was approximately 9:30 p.m. at the time in question. All of these facts support an affirmative finding of reasonable suspicion under the factors set forth above, and Agent Izaguirre was justified in making an investigatory stop. There has been no violation of the Fourth Amendment.
It is therefore ORDERED that Defendant’s Motion to Suppress (Dkt.# 14) is DENIED.
. The Court has relied on the testimony of Agent Izaguirre and the facts contained in the investigative report. Defense counsel confirmed at the hearing that the facts in this case are generally undisputed, and the issues in dispute are legal, rather than factual.
Notes
. At the hearing, defense counsel alluded to a "greater" expectation of privacy when traveling in the dark; however, there is no legal support for such an argument.
