*1 Before GARWOOD, SMITH, and BENAVIDES, Circuit Judges.
GARWOOD, Circuit Judge:
Defendants-appellants Miguel Angel Aguero-Miranda (Aguero- Miranda), Ricardo Vasquez (Vasquez), and Antonio Ibarra-Sanchez (Ibarra-Sanchez) were indicted for conspiracy to possess marihuana with intent to distribute in violation of 21 U.S.C. §§ 841(a)(1) *2 and 846. The appellants moved to suppress approximately 344 pounds of marihuana seized on January 6, 1998 from the van in which they were riding, as well as inculpatory statements that they made to law enforcement officials after their arrest. Following an evidentiary hearing, the district court denied the motion. The appellants thereafter were convicted on their pleas of guilty and were subsequently sentenced. The guilty pleas each reserved the right to appeal the denial of the motion to suppress. F ED . R. C RIM . P ROC . 11 (a)(2). The appellants now appeal, challenging only the denial of the motion. We affirm.
Facts and Proceedings Below Between August, 1997, and January, 1998, special agents of the Drug Enforcement Agency (DEA), led by Special Agent Steve Mattas (Mattas), conducted intermittent surveillance of a residence located at 1393 Copper Ridge in El Paso, Texas. This residence was the home of appellant Aguero-Miranda, his wife, Jacqueline Aguero, and her children. Based on their observations over this five-month period, Mattas and the other agents suspected that the Copper Ridge residence housed an on- going illicit drug operation.
From their surveillance of the trash at the Copper Ridge residence, Mattas and the DEA agents discovered phone records revealing that multiple calls had been made to phone numbers associated with other DEA investigations. Their searches also revealed several five-pound zip- lock baggies covered with duct tape, a practice which in Mattas’s experience was consistent with the transportation of drugs and currency. A police dog trained to detect the presence of currency positively *3 identified the baggies as having contained currency. Other suspicious trash findings included plane tickets to Hawaii and Mexico, bills that were all in Mrs. Aguero’s name, and bank statements indicating large monthly deposits, even though the residents at Copper Ridge had no discernable employment.
The trash searches also revealed utility bills and mortgage statements for a residence on Rainbow Ridge, located directly behind the Copper Ridge home. His attention drawn to the Rainbow Ridge residence, Mattas noted that it was unkempt and run-down, which was unusual for that affluent part of El Paso. No one appeared to be living there on any consistent basis, and the agents observed heavy foot and vehicle traffic between the two residences. From these observations, Mattas surmised that the Rainbow Ridge residence was in all likelihood a “stash house,” that is, an unoccupied house used for the storage of drugs.
In the course of his surveillance of the Copper Ridge and Rainbow Ridge residences, Mattas observed approximately six vehicles, including the beige van at issue in this appeal, coming and going from the houses at various times. Some of the vehicles had temporary license tags, some had tags that were associated with other DEA investigations, and some would remain parked in front of the houses, virtually abandoned, for weeks at a time. At the suppression hearing, Mattas testified that this large number of vehicles was unusual even for an affluent area–and especially unusual when the residents did not appear to work. Mattas concluded that this activity was consistent with drug trafficking. He also identified one of the most frequent visitors to the Copper Ridge house as Gilberto Villanueava (Villanueava), whom the agents later (and *4 before January, 1998) determined was wanted for questioning in connection with the abduction of a DEA agent in Mexico in 1995, as well as another DEA investigation. According to Mattas, Villanueava often shuttled back and forth between the Copper Ridge and Rainbow Ridge residences, and unlike most of the other visitors, was actually allowed inside the Copper Ridge residence.
On the evening of January 6, 1998, the beige van made its first appearance in over a month. As the van pulled into the driveway of the Rainbow Ridge residence, Mattas observed the motion-sensitive light above the driveway go on and at least two individuals exit the van and enter the residence. A minute or two later, the van left the Rainbow Ridge residence; after approximately thirty minutes, it returned. Mattas then saw three men loading several large objects, which appeared to be duffel bags, into the van. He testified that sometime during the course of these events the motion-sensitive light had been deactivated, and that the loading of the van took place in the dark. Mattas found it suspicious that these individuals would load the van in the dark “when the average person would have wanted to have light out there so they could see what they were doing.”
Mattas followed the van as it departed from Rainbow Ridge. Believing that the van was loaded with drugs, and that he would need assistance in stopping it, Mattas contacted by mobile phone another DEA agent and the El Paso Police Department (EPPD). [1] He instructed the EPPD *5 dispatcher to relay a message to EPPD officers that a DEA agent needed assistance in stopping the van. Mattas also requested the dispatcher to tell the officers to form their own reasonable suspicion before stopping the van. The dispatcher failed to communicate this last instruction, however, and instead merely issued a radio bulletin that a DEA agent had requested assistance in stopping the beige van because it was possibly transporting drugs or weapons.
After hearing the bulletin, EPPD Patrolman Jose Guerra (Guerra) observed the van heading east on Interstate 10. Guerra activated his emergency lights and began his pursuit. While being followed on the freeway by Guerra, the van passed an EPPD Special Weapons and Tactics (SWAT) team on its way home from a training session at the police academy. Aware of the dispatcher’s message, the SWAT team joined in the chase and aided Guerra in making a “felony stop” of the van at an exit off the highway. [2] The SWAT team, Guerra, and Guerra’s partner all approached the stopped van with pistols and shotguns drawn. As they drew near, but before they looked inside it, the officers could smell a strong odor of marihuana emanating from within the van. [3] The officers ordered the three occupants–driver appellant Ibarra-Sanchez, front seat passenger appellant Aguero-Miranda, and back seat passenger appellant Vasquez–to exit the van and kneel down on the ground. Guerra handcuffed the men and with the help of other officers placed them in the back *6 seats of three separate patrol cars. The officers then conducted a “protective sweep” of the van for other occupants or weapons, and discovered three duffel bags, as well as some smaller bags, which were later determined to contain approximately 344 pounds of marihuana.
At some point during this time period, Mattas arrived and identified himself as the agent who had requested the stop. The officers informed Mattas that they had conducted the protective sweep of the van and had discovered a large amount of marihuana. Mattas later testified that he could smell the marihuana when he was five or ten feet away from the van. After conferring with the EPPD officers, Mattas seized the marihuana. The appellants were then formally arrested and taken to EPPD headquarters, where Aguero-Miranda and Vasquez made inculpatory statements to EPPD officers. Ibarra-Sanchez made no post- arrest statements.
The appellants were charged in a one-count indictment with conspiracy to possess marihuana with intent to distribute in violation of 21 U.S.C. §§ 841(a)(1) and 846. Arguing that the initial “felony stop” constituted an arrest and search for which there was no probable cause, the appellants filed a motion to suppress the marihuana and statements. The district court conducted a suppression hearing on June 12, 1998, and denied the motion on July 7, 1998 in a memorandum order. The appellants then pleaded guilty to the indictment, reserving the right to appeal the denial of the motion. On October 16, 1998, the district court sentenced Aguero-Miranda to sixty months of imprisonment, followed by a four year period of supervised release; Vasquez to thirty- seven months of imprisonment and three years of supervised release; and *7 Ibarra-Sanchez to thirty months of imprisonment and three years of supervised release. The appellants now appeal, complaining only of the denial of their suppression motion. [4]
Discussion
The district court found that in conducting the “felony stop,” the
EPPD officers “effected a warrantless arrest of the van’s occupants and
then proceeded to search it,” all without probable cause. The court
denied the motion, however, on the basis of the “good faith” exception
to the exclusionary rule of the Fourth Amendment. See United States v.
Leon ,
When reviewing a district court’s ruling on a motion to suppress
*8
based on live testimony at a suppression hearing, we will accept the
court’s factual findings “unless the findings are clearly erroneous or
influenced by an incorrect view of the law.” United States v. Lanford ,
I. Reasonable Suspicion to Stop the Van
The appellants contend that the EPPD officers lacked reasonable
suspicion to stop the van. We disagree. Under the principles of Terry
v. Ohio ,
It is clear that when Mattas made the call to the EPPD dispatcher,
he possessed reasonable suspicion to stop the van himself. Over the
five-month period of surveilling the Copper Ridge and Rainbow Ridge
residences, Mattas and the other agents discovered a veritable
*9
cornucopia of factors suggesting drug-related activities: currency
wrappers; phone records connecting the residents to other DEA
investigations; plane tickets to at least one known drug source country
(Mexico); the fact that the Copper Ridge records were all in Aguero-
Miranda’s wife’s name (thus insulating Aguero-Miranda’s identity and
possibly protecting the house from criminal forfeiture); the lack of any
visible employment on the part of the residents; the Rainbow Ridge
“stash house” nearby; the motley fleet of vehicles appearing
sporadically at the two residences; and the regular presence of
Villanueava, a suspected drug trafficker. On the evening of January 6,
1998, Mattas and the other agents also observed the beige van twice
arrive and depart from the Rainbow Ridge residence, and the three men
load the van with large duffel bags while in complete darkness. Any
analysis of reasonable suspicion is necessarily fact-specific, and
factors which by themselves may appear innocent, may in the aggregate
rise to the level of reasonable suspicion. See id. at 1880-81. See
also United States v. Holloway ,
We note that, notwithstanding the appellants’ argument to the
contrary, the fact that Mattas had not previously obtained a search or
arrest warrant is not fatal to the propriety of the stop. Even if
Mattas would have been successful in obtaining a warrant before the
stop, officers are not required to do so as soon as it is practicable
to do so. See United States v. Carillo-Morales ,
The actual stop of the van by the EPPD officers was lawful because
under what is sometimes referred to as the “collective knowledge”
doctrine, the officers shared Mattas’s reasonable suspicion. The
officers stopped the van in reliance on the dispatcher bulletin, and
therefore were not required to have personal knowledge of the evidence
that created Mattas’s reasonable suspicion. See United States v.
Hensley ,
II. Probable Cause to Search
Appellants contend that the EPPD officers had no probable cause to
conduct either a search or an arrest, but in fact it is quite clear that
the officers had probable cause to search the van. After stopping the
van, the EPPD officers approached it with their weapons drawn. As they
did so, they detected the distinct odor of marihuana wafting out. The
officers then ordered the appellants out of the van and conducted a
“protective sweep.” At the suppression hearing, a member of the SWAT
team testified that he smelled the marihuana when he was two or three
feet away from the van, and Mattas testified that he could smell it from
*12
five to ten feet away. Regardless of precisely how near or far from the
van the officers were when they detected the odor, once they did so they
possessed probable cause to search the van. This Court has consistently
held that the smell of marihuana alone may constitute probable cause to
search a vehicle. See , e.g. , McSween ,
The appellants further contend that even if the initial stop of the van was lawful, the EPPD officers violated the appellants’ Fourth Amendment rights by ordering them out of the van, pointing their weapons at them, forcing them to kneel on the ground, handcuffing them, and then placing them in the back of police vehicles. The appellants argue that the EPPD officers converted a Terry stop based on reasonable suspicion into a full-blown arrest for which the officers had no probable cause. We conclude that whether or not this show of force amounted to a de facto arrest is ultimately irrelevant because neither the evidence seized from the van nor the appellants’ later statements were not a product of the alleged arrest.
The EPPD officers acted lawfully by ordering the occupants to exit
the van after the stop. It is settled that officers conducting a lawful
Terry stop of a vehicle may order both the driver and the passengers to
exit the vehicle pending completion of the stop. In Pennsylvania v.
Mimms ,
Whether the officers’ subsequent conduct–training their weapons on
the appellants, ordering them to kneel, handcuffing them, and then
placing them in squad cars–amounted to a warrantless arrest is unclear.
As we have observed, “[t]he line between a valid investigatory stop and
an arrest requiring probable cause is a fine one.” United States v.
Hanson ,
We do not resolve this issue, for even if the show of force by the
officers constituted an illegal arrest, it would not affect our ultimate
disposition because neither the drugs nor the statements were products
*15
of the alleged post-stop arrest. To warrant suppression, the challenged
evidence must have been obtained “by exploitation of [the alleged]
illegality” rather than “by means sufficiently distinguishable to be
purged of the primary taint.” Wong Sun v. United States ,
In this case, the marihuana and statements were not gained by “exploitation” of the allegedly illegal arrest. As discussed above, the EPPD officers smelled the marihuana as they approached the van and thereby had probable cause to search the van while the appellants were still inside. Similarly, the statements were taken at EPPD headquarters after formal arrest based on the discovery of the marihuana. The reasonable suspicion to stop the van developed into probable cause to search it when the marihuana was smelled, and once the marihuana was discovered, the officers lawfully arrested the appellants. After the appellants were ordered out of the van, it made no difference to the ultimate result whether they stood by the side of the road or sat handcuffed in police cars: in either situation, the officers would have discovered the marihuana and arrested them. In short, there is no *16 causal link between the alleged “arrest” of the appellants and the evidence later introduced at trial; the drugs and statements were not fruits of that particular tree. Therefore there is no reason to suppress the marihuana or the statements.
Conclusion The district court’s order denying the appellants’ motion to suppress, and appellants’ convictions and sentences, are AFFIRMED.
Notes
[1] At the suppression hearing, Mattas testified that he did not attempt to stop the van himself because his vehicle was not equipped with emergency lights or a siren, and because he did not want to reveal the existence of the DEA investigation to Aguero-Miranda or any of the van’s other occupants.
[2] While not entirely clear, it appears that a “felony stop” is a detention procedure that involves ordering occupants of a vehicle to exit when police officers believe their safety is at risk.
[3] One member of the SWAT team, Lawrence Lujan, testified at the suppression hearing that he could smell the marihuana two or three feet away from the van.
[4] The separate appeal of Ibarra-Sanchez (No. 98-50999) has been consolidated with that of Aguero-Miranda and Vasquez (No. 98-51044).
[5] “The reasonable suspicion standard does not require . . . that the
circumstances be such that there is no reasonable hypothesis of innocent
behavior.” United States v. Basey ,
[6] The parties make much of the dispatcher’s failure to relate Mattas’s instruction that the EPPD officers form their own reasonable suspicion before stopping the van. This argument is immaterial, however, because under the “collective knowledge” doctrine, the EPPD officers did not need to form their own suspicion. The admissibility of the evidence recovered during this lawful stop turns on whether Mattas, the officer who made the request for assistance, possessed the requisite reasonable suspicion to make the stop. See Hensley , 105 S.Ct. at 681 (discussing a similar point in the context of probable cause to arrest). Having established that Mattas did have sufficient reasonable suspicion to stop the van, the dispatcher’s error is irrelevant.
[7] We note that the subsequent “protective sweep” might also be
justified under Michigan v. Long ,
