UNITED STATES COURT OF APPEALS

FOR THE SIXTH CIRCUIT

UNITED STATES OF AMERICA,

Plaintiff-Appellee,

v.

JONATHAN MENDOZARICARDO,

Defendant-Appellant.

ON APPEAL FROM THE UNITED 

STATES DISTRICT COURT FOR 

THE EASTERN DISTRICT OF 

KENTUCKY

BEFORE: CLAY, ROGERS, and DONALD, Circuit Judges.

CLAY, Circuit Judge. Defendant Jonathan Mendoza-Ricardo appeals his criminal 

conviction after pleading guilty to a conspiracy to distribute large quantities of marijuana. See

21 U.S.C. §§ 841(a)(1), 846. On appeal, Mendoza-Ricardo challenges his detention at a traffic stop 

as unreasonable, and thereby seeks to suppress his later confession. For the reasons that follow, 

we disagree and affirm Mendoza-Ricardo’s conviction.

I. BACKGROUND

In early February 2019, Bryn Elton—a special agent with Homeland Security 

Investigations (“HSI”)—was in Phoenix, Arizona, “conducting surveillance on a suspected 

narcotics trafficker.” (Hearing Tr., R. 125 at PageID #397, #400–01.) While monitoring that 

suspected trafficker, Agent Elton and her colleagues saw him load what they suspected to be bales 

of marijuana into the back of a Toyota Highlander. They decided to follow the Highlander, the 

start of what turned into a two-day “trip from hell,” in which the agents were led from state to state 

until finally arriving in Kentucky. (Id. at #401–02.)

When they reached the Lexington area, Elton says the vehicle performed a 

“countersurveillance run” in the parking lot of a shopping mall, after which it proceeded to a 

residence in Nicholasville, Kentucky, and backed into the driveway. (Id. at #402–03.) The HSI 

agents then set up surveillance around the house and began a stakeout. They also asked for support 

from local law enforcement, in case they needed uniformed officers to conduct a traffic stop or 

otherwise assist the agents with their work. One of the HSI agents, Matthew Hall, met with 

Nicholasville Police Department officers, informed them of the operation, and gave them a radio; 

the Nicholasville officers agreed to help if they could.

At one point during the stakeout, a white work truck arrived at the house. The two men in 

the truck exited the vehicle, took small, grocery-store-type plastic bags from the truck, and walked 

into the house without knocking. According to Elton, the house in question appeared to be a stash 

house, meaning a location used for storing drugs. Based on her experience and training, drug 

dealers will not allow third parties into a stash house, and so it is very likely that anyone entering 

the house was involved in the conspiracy.

After spending some time in the house, the two men returned to their truck and started to 

drive away. The car drove directly by Elton, who recognized the man sitting in the passenger seat 

as Fabian Zavala-Romero, an undocumented immigrant who was suspected of involvement in a 

large-scale narcotics operation in the Lexington area. At that point, Elton notified the team over 

the radio that Zavala-Romero was in the truck, and that the agents “had probable cause to stop and 

detain him for a minimum of those immigration violations, in addition to the suspected narcotics

violations that were going on at that house.” (Id. at #406.) Elton then heard officers and agents on 

the radio coordinating a traffic stop of the white truck.

Nicholasville officer Jeff Fryman, one of the officers who previously met with Agent Hall, 

heard over the radio that a white work truck had left the suspected stash house. He then saw a 

white truck near the location reported by the HSI agents and began to follow it under HSI’s 

direction. Fryman says he recalls agents mentioning either one or two occupants of the vehicle, 

that “one of the men in the vehicle was at least one of the ones that they had been watching,” and 

that one of the people in the vehicle was undocumented. (Id. at #424.) Fryman called for marked 

patrol units to come assist them with a potential traffic stop, and Agent Hall was also following 

behind Fryman but was caught in traffic.

Eventually, HSI directed Nicholasville police to stop the vehicle. According to Fryman, 

the stop was “[b]ased on [HSI’s] investigation and the immigration status of one of the occupants.” 

(Id. at #425.) Fryman says that officers then stopped the vehicle, spoke with its occupants, and 

detained both of them. The two people in the car were ultimately identified as Zavala-Romero—

the man whom Agent Elton recognized earlier—and Jonathan Mendoza-Ricardo, the defendant in 

this appeal. Fryman also said that HSI suspected both occupants of the vehicle of involvement in 

the drug conspiracy, and specifically asked Fryman to detain both of them, not just ZavalaRomero.

While Agent Hall had earlier been following the Nicholasville officers, he never made it 

to the scene of the traffic stop. Instead, before he got there, he activated his emergency equipment 

and raced back to the house; Fryman believes this occurred after radio reports came in of a man at 

the stash house trying to flee through a window. Whatever the cause, the Nicholasville officers 

were left at the scene alone, which Fryman describes as follows:

After we detained [Zavala-Romero and Mendoza-Ricardo], we 

pretty much didn’t do anything. We waited. I can’t remember if I 

talked on the cell phone or the radio to Special Agent Hall because

- 4 -

he was the one we had the most conversation with or communication 

with. But he told us that somebody [else] from HSI was going to be 

coming to our traffic stop.

(Id. at #427–28.) Fryman says it took ten to fifteen minutes for this other agent to arrive at the 

scene, during which the officers were still trying to confirm the identities of Zavala-Romero and 

Mendoza-Ricardo.

In his testimony, Fryman also noted the Nicholasville officers’ desire to wait for HSI to 

arrive so they could interview the pair themselves:

Q. . . . [B]ased on your training and experience, you typically, if 

you’re less familiar with the investigation, would you wait for [a

different] officer to question suspects?

A. A hundred percent.

Q. That’s just because they’re more familiar with the facts?

A. Exactly.

(Id. at #428.)

Meanwhile, back at the house, agents saw a man exit the home, open up the Highlander, 

and start moving black objects, which based on the surveillance in Phoenix, the agents believed 

were bales of marijuana. Elton testified that in her experience, once a shipment of drugs reaches a 

stash house, many other vehicles may soon arrive to pick up their share of the drugs, and so the 

time for the agents to act was shrinking. As a result, the agents decided to secure the house and 

moved in to surround it. When they did this, someone tried to jump out of a back window but 

returned into the house when he saw other agents. Officers called out for the occupants to surrender 

and exit the home, and eventually two men left the house and were taken into custody.

After the two men at the house were detained, HSI agent Brian Patterson, who was then at 

the house, was instructed to take his partner and go to the scene of the traffic stop instead. 

 Case: 19-6125 Document: 27-2 Filed: 06/15/2020 Page: 4
United States v. Mendoza-Ricardo No. 19-6125

According to Agent Elton, all of the events at the house occurred within approximately fifteen 

minutes, and Patterson too says he arrived at the traffic stop between fifteen and twenty minutes 

from the time that it started. After Patterson arrived, he introduced himself to the Nicholasville 

officers at the scene, reviewed some documents that the officers recovered, and began interviewing 

the two men from the truck.

Back at the house, one of the men who surrendered there, Fabian Noperi, had previously 

been identified as a suspected narcotics smuggler and was one of the individuals whom agents saw 

in the Highlander as it drove from Arizona to Kentucky. After he was Mirandized, Noperi admitted 

that there were narcotics and guns in the house, and told agents that the two occupants of the white 

work truck had left to get money to pay for the drugs. Agents at the house then told Patterson that 

the occupants of the white truck were part of the drug conspiracy and should continue to be 

detained. Consequently, the two were transported to the Nicholasville Police Department for 

further interviews.

Once at the police department, Mendoza-Ricardo admitted his involvement in the drug 

conspiracy. A federal grand jury then indicted him for conspiracy and possession with intent to 

distribute over 100 kilograms of marijuana.

Following the indictment, Mendoza-Ricardo moved to suppress the statements he made at 

the police station after his arrest. Mendoza-Ricardo admits that officers had adequate grounds to 

make the initial traffic stop of his vehicle, and that they had probable cause to arrest him at the 

time they took him back to the station.1 But Mendoza-Ricardo claims that the traffic stop was 

unconstitutionally prolonged because the purpose of the stop was to arrest his passenger, Zavala1 Mendoza-Ricardo initially argued that his arrest was not supported by probable cause, 

but he expressly abandoned that argument on appeal.

Romero, for his immigration violation. And since that arrest happened immediately after the traffic 

stop began, Mendoza-Ricardo says he should have been free to go. Instead, he was detained at the 

scene of the traffic stop until Agent Patterson arrived, at which point Mendoza-Ricardo was taken 

to the station house and arrested. Thus, Mendoza-Ricardo claims that his subsequent confession 

was a product of this unconstitutional detention, and so should be suppressed.

After holding a hearing, the district court denied Mendoza-Ricardo’s motion. The district 

court found that officers had three purposes for stopping the white work truck: (1) to detain and 

question Zavala-Romero for his immigration violation, (2) to determine the identity of the 

vehicle’s driver, since he was transporting Zavala-Romero, and (3) to question both of them about 

their suspected involvement in the drug conspiracy. On this last point, the court found that the 

agents had a reasonable suspicion that Mendoza-Ricardo was part of the drug conspiracy, and that 

this reasonable suspicion supported detaining him in order to question him about his activities at 

the suspected stash house. Because the total length of the traffic stop was approximately twentyfour minutes, because it took just over fifteen of those minutes for Patterson to arrive, and because 

officers were still searching the truck and attempting to confirm the passengers’ identities during 

that period, the court held that the stop was not unconstitutionally prolonged.

After the district court denied his motion, Mendoza-Ricardo entered into a conditional plea 

agreement in which he reserved the right to challenge the district court’s suppression ruling. The 

court then sentenced him to the mandatory minimum of five years’ imprisonment. On appeal, 

Mendoza-Ricardo says that the district court erred in denying his suppression motion because the 

traffic stop was unconstitutionally prolonged.

II. DISCUSSION

A. Standard of Review

“When reviewing a district court’s decision on a motion to suppress, we use a mixed 

standard of review: we review findings of fact for clear error and conclusions of law de novo.” 

United States v. Cochrane, 702 F.3d 334, 340 (6th Cir. 2012) (quoting United States v. See, 

574 F.3d 309, 313 (6th Cir. 2009)). Further, “[w]hen a district court has denied a motion to 

suppress, this Court reviews the evidence in the light most likely to support the district court’s 

decision.” Id. (quoting United States v. Adams, 583 F.3d 457, 463 (6th Cir. 2009)). The application 

of facts to the law, which in this case includes the question of whether the duration of the stop was 

permissible, is reviewed de novo. United States v. Torres-Ramos, 536 F.3d 542, 550 (6th Cir. 

2008); United States v. Townsend, 305 F.3d 537, 541 (6th Cir. 2002).

B. Analysis

In this appeal, Mendoza-Ricardo argues that his detention at the traffic stop was 

unconstitutionally extended, requiring the suppression of statements he made to police after he 

was arrested at the end of the stop. According to Mendoza-Ricardo, the purpose of the traffic stop 

was to arrest his passenger, Zavala-Romero, for immigration violations, and so once officers 

completed that task, he should have been free to leave. But the record shows that HSI agents 

directed officers to stop the vehicle as part of their narcotics investigation, based on their suspicion 

that both occupants of the truck were involved in a drug trafficking conspiracy being run out of 

the suspected stash house. And while Mendoza-Ricardo also argues that the stop took too long 

because officers held him at the scene until Agent Patterson arrived, it was reasonable for officers 

to wait approximately fifteen minutes until a federal agent responsible for the case could arrive to 

interview the suspects. Accordingly, we must affirm Mendoza-Ricardo’s conviction.

A traffic stop is usually “more akin to an investigative detention rather than a custodial 

arrest, and the principles announced in Terry v. Ohio, 392 U.S. 1 (1968), apply to define the scope 

of reasonable police conduct.” United States v. Davis, 430 F.3d 345, 353 (6th Cir. 2005) (quoting 

United States v. Bailey, 302 F.3d 652, 657 (6th Cir. 2002)). Under that framework, “[a] temporary 

detention for questioning does not require a showing of probable cause if it is justified by specific 

and articulable facts that give rise to a reasonable suspicion of criminal activity.” United States v. 

Palomino, 100 F.3d 446, 449 (6th Cir. 1996).

The Fourth Amendment inquiry for a Terry stop includes two related parts. First, the court 

must determine “whether there was a proper basis for the stop, which is judged by examining 

whether the law enforcement officials were aware of specific and articulable facts which gave rise 

to reasonable suspicion.” United States v. Garza, 10 F.3d 1241, 1245 (6th Cir. 1993) (quoting 

United States v. Hardnett, 804 F.2d 353, 356 (6th Cir. 1986)). Second, the court must decide 

“whether the degree of intrusion . . . was reasonably related in scope to the situation at hand, which 

is judged by examining the reasonableness of the officials’ conduct given their suspicions and the 

surrounding circumstances.” Id. (quoting Hardnett, 804 F.2d at 356); see also Davis, 430 F.3d at 

353 (“[A]ny subsequent detention after the initial stop must not be excessively intrusive in that the 

officer’s actions must be reasonably related in scope to circumstances justifying the initial 

interference.” (quoting United States v. Hill, 195 F.3d 258, 264 (6th Cir. 1999))); Townsend, 305 

F.3d at 541 (same).

The first issue on appeal is the purpose of the traffic stop, and specifically whether that 

stop was performed in part to question Mendoza-Ricardo about his role at the suspected stash 

house. This is important because the purpose of the stop affects what length of detention is 

reasonable and what facts are considered when performing this analysis. See Rodriguez v. United 

 Case: 19-6125 Document: 27-2 Filed: 06/15/2020 Page: 8
United States v. Mendoza-Ricardo No. 19-6125

States, 575 U.S. 348, 354 (2015) (“Like a Terry stop, the tolerable duration of police inquiries in 

the traffic-stop context is determined by the seizure’s ‘mission’ . . . .” (quoting Illinois v. Caballes, 

543 U.S. 405, 407 (2005)); Torres-Ramos, 536 F.3d at 550–51 (noting the scope of the traffic stop 

as a factor in the Fourth Amendment analysis).

The district court found that one of the purposes of the traffic stop was to question both 

Mendoza-Ricardo and Zavala-Romero about their involvement in the drug conspiracy. MendozaRicardo objects to this finding and argues that the traffic stop was really focused on ZavalaRomero’s immigration status, not on Mendoza-Ricardo’s own suspected involvement in the drug 

conspiracy. But this misconstrues the witnesses’ testimony, which confirms that the stop was made 

at HSI’s direction and as part of their investigation of the suspected stash house. (See Hearing Tr., 

R. 125 at PageID #425 (“Q. And what was the basis of the stop? A. Their direction was to go ahead 

and make the stop. Q. Based on the immigration status? A. Based on their investigation and the 

immigration status of one of the occupants, yes.” (emphasis added)); id. at #438 (“Q. Also, with 

respect to Mr. Mendoza, was it your understanding that the HSI agents did suspect him of being

involved in the drug trafficking activity? A. Yes. Q. And they actually asked you to detain him as 

well? A. Correct.”).) Even if there were some ambiguity in this testimony, the district court did 

not clearly err in finding that investigating Mendoza-Ricardo’s involvement in the drug conspiracy 

was one of the purposes of the stop. This is particularly true given the context of this appeal, where 

we must construe the facts in the light most favorable to the government. Cochrane, 702 F.3d at

340.

To be sure, “[a] court cannot determine that an officer had reasonable suspicion on the 

basis of a factor on which the officer did not actually rely.” Townsend, 305 F.3d at 541. But in this 

case, the Nicholasville officers stopped Mendoza-Ricardo at HSI’s direction, which in turn 

 Case: 19-6125 Document: 27-2 Filed: 06/15/2020 Page: 9
United States v. Mendoza-Ricardo No. 19-6125

- 10 -

implicates the collective knowledge doctrine. Under that doctrine, “an officer may conduct a stop 

based on information obtained by fellow officers” rather than information the detaining officer 

herself possesses. United States v. Lyons, 687 F.3d 754, 765–66 (6th Cir. 2012). This doctrine 

applies “whenever a responding officer executes a stop at the request of an officer who possesses 

the facts necessary to establish reasonable suspicion,” since in that case, the responding officer is 

effectively acting as the other officer’s agent. Id. at 766; see also id. at 767 (outlining the scope of 

this doctrine). The record here shows that HSI directed officers to stop the work truck, and so 

HSI’s purpose for making that request is the relevant question for our Fourth Amendment inquiry. 

Because that purpose included questioning the vehicle’s occupants about their activities inside the 

suspected stash house, and because the agents had reasonable suspicion of that criminal activity, 

we proceed to assess whether the length of Mendoza-Ricardo’s detention was reasonable in light 

of that purpose.

While reasonable suspicion can support stopping a vehicle for the purpose of investigating 

non-traffic criminal activity, see, e.g., United States v. Arvizu, 534 U.S. 266, 271–72, 277–78 

(2002), the subsequent detention must still be reasonable under the Fourth Amendment. “Although 

an officer may have reasonable suspicion to detain a person or his possessions for investigation, 

the officer’s investigative detention can mature into an arrest or seizure if it occurs over an 

unreasonable period of time or under unreasonable circumstances.” United States v. Avery, 

137 F.3d 343, 349 (6th Cir. 1997). Thus, “a police stop exceeding the time needed to handle the 

matter for which the stop was made violates the Constitution’s shield against unreasonable 

seizures.” Rodriguez, 575 U.S. at 350; accord, e.g., Miller v. Maddox, 866 F.3d 386, 393–94 (6th 

Cir. 2017).

 Case: 19-6125 Document: 27-2 Filed: 06/15/2020 Page: 10
United States v. Mendoza-Ricardo No. 19-6125

- 11 -

In making this assessment, we look to whether the detention was (1) sufficiently limited in 

time and (2) involved the least intrusive means that were reasonably available. Davis, 430 F.3d at 

354. Thus, “an investigative detention must be temporary and last no longer than is necessary to 

effectuate the purpose of the stop.” Florida v. Royer, 460 U.S. 491, 500 (1983) (plurality opinion). 

This means that the police must have “diligently pursued a means of investigation that was likely 

to confirm or dispel their suspicions quickly, during which time it was necessary to detain the 

defendant.” United States v. Sharpe, 470 U.S. 675, 686 (1985); accord, e.g., Hoover v. Walsh, 682 

F.3d 481, 497–98 (6th Cir. 2012); Davis, 430 F.3d at 356–57. Furthermore, “[o]nce the purpose 

of the initial traffic stop is completed, an officer cannot further detain the vehicle or its occupants 

unless something happened during the stop” that provides additional reasonable suspicion. Davis, 

430 F.3d at 353; accord, e.g., Torres-Ramos, 536 F.3d at 550.

In this case, the record shows that after Mendoza-Ricardo was detained, he was held at the 

scene of the traffic stop for approximately fifteen minutes until Agent Patterson could arrive. 

Officer Fryman testified that this delay was necessary so that HSI agents could be the ones who 

questioned Mendoza-Ricardo, since they were the ones who had knowledge of the facts of the 

case.

There were clear benefits to allowing federal agents—who directed the stop and were 

responsible for the investigation—to question these suspects instead of officers who were just 

informed of the investigation earlier that same day. And in the face of suspected narcotics 

trafficking, this Court has routinely upheld detentions longer than the one at issue here for a drugsniffing dog to arrive. See, e.g., United States v. Perez, 440 F.3d 363, 367–69, 372–73 (6th Cir. 

2006) (approximately one hour); Davis, 430 F.3d at 354–55 (approximately thirty minutes). 

Mendoza-Ricardo does not explain why a delay for an agent to arrive is meaningfully different, 

 Case: 19-6125 Document: 27-2 Filed: 06/15/2020 Page: 11
United States v. Mendoza-Ricardo No. 19-6125

- 12 -

and in fact, he never addresses in his briefing on appeal why waiting fifteen minutes for Agent 

Patterson was unreasonable. The length and manner of this delay were “reasonably related in scope 

to the circumstances which justified the interference in the first place”—namely, HSI agents’ 

suspicion of Mendoza-Ricardo’s involvement in drug trafficking—and so the brief wait for Agent 

Patterson to arrive does not offend the Fourth Amendment. Terry, 392 U.S. at 19–20.

Mendoza-Ricardo also argues that upholding the stop in this case would allow open-ended 

detentions for as long as officers need in order to conduct an interview, but the Supreme Court is 

clear that a Terry stop is only permissible until its purposes either “are—or reasonably should have 

been—completed.” Rodriguez, 575 U.S. at 354 (emphasis added); see also Sharpe, 470 U.S. at 

685 (“Obviously, if an investigative stop continues indefinitely, at some point it can no longer be 

justified as an investigative stop.”). And so, while an extended delay waiting for Agent Patterson 

to arrive at the scene might have violated the Fourth Amendment because Mendoza-Ricardo’s 

interview “reasonably should have been” completed sooner, Rodriguez, 575 U.S. at 354, the 

approximately fifteen-minute wait at issue here falls well short of that goalpost. This is especially 

true when considering the events at the suspected stash house, which required HSI to pull Agent 

Hall off his route to the traffic stop to help secure the scene. See Perez, 440 F.3d at 372–74 (holding 

that investigation activity at another location can support a continued detention following a Terry

stop).

III. CONCLUSION

While Mendoza-Ricardo argues that the purpose of his traffic stop was completed as soon 

as officers arrested his passenger, the record shows that a key purpose of the stop was to question 

Mendoza-Ricardo regarding his activities at the suspected stash house. Having one of the HSI 

agents responsible for that investigation question him was reasonably related to that purpose, and 

 Case: 19-6125 Document: 27-2 Filed: 06/15/2020 Page: 12
United States v. Mendoza-Ricardo No. 19-6125

- 13 -

the delay of approximately fifteen minutes needed for this to happen was not unreasonable under 

the circumstances. Accordingly, the officers’ detention of Mendoza-Ricardo did not violate the 

Fourth Amendment, and so we affirm his conviction.
