After deplaning at San Juan International Airport, defendants Amado Fernandez Ventura and Milagros Cedeno were questioned by Customs agents and arrested for illegally transporting money, in violation of 31 U.S.C. § 5316. They filed a motion to suppress all inculpatory statements made in the absence of Miranda warnings, which was granted. The government appealed. Having concluded that the district court applied an erroneous legal test, we remand for reconsideration of the suppression motion under thе proper standard.
BACKGROUND
Facts
Because of his frequent travel between St. Maarten and Puerto Rico, Fernandez was on a “lookout” list kept by the Customs Service. On November 12, 1994, after clearing immigration, Fernandez was taken to a secondary Customs inspеction area. One agent asked Fernandez if he was carrying any money; Fernandez responded “$8000.” Another agent searched his suitcase, discovered women’s lingerie, and asked whom it belonged to. Fernandez answered “mi mujer,” which colloquially means “my wife” or “my woman.” Fernandez was directed to find her.
Cedeno, Fernandez’s girlfriend, had already cleared customs but was still within the customs area. Fernandez, while accompanied by an agent, located Cedeno and returned with her to the seсondary inspections area. On the way there, the agent asked Cedeno whether she was carrying any money. She replied that she was carrying approximately $9,000.
A search of the defendants revealed that the actual amount in their pоssession was $16,166. In response to further questioning, Fernandez revealed that the money belonged to his money exchange company, of which he was president. The agents then placed the couple under arrest and read them their Miranda rights.
The defеndants were charged with failing to report the transportation of monetary instruments in excess of $10,000 in violation of 31 U.S.C. § 5316, and making false statements to the Customs Service in violation of 18 U.S.C. § 1001. Upon their motion alleging a
Miranda
violation, the court suppressed all stаtements made by the defendants after Cedeno was asked whether she was carrying any money.
See United States v. Fernandez Ventura,
The District Court’s Opinion
The district court delineated four relevant inquiries for determining whether the rule enunciated in
Miranda v. Arizona,
1. Was the person in “custody”?
2. Was the person “interrogated”?
3. Had the Fifth Amendment right against self-incrimination attached?
4. Had the Sixth Amendment right to counsel attached?
Under the court’s analysis, a violation occurs when “each element (custody, un-Mirandized interrogation, and attached Fifth and Sixth *710 Amendment rights) ... exist[s] simultaneously.”
The court considered each factor. It stated that custody “depends exclusively upon whether a reasonable persоn in the defendant’s position would have felt free to leave.” Because “Customs is an inherently coercive environment [in that] an individual is never free to simply walk away,” the court concluded that defendants were in “custody.” In the court’s view, “interrogation” was satisfied because “[t]he parties do not dispute that all of the questioning conducted by Customs officers in this ease constituted ‘interrogation’ as defined and explained in
Rhode Island v. Innis,
Most of the court’s analysis focused on whether the rights to silence and counsel had attached. The court held that “in the context of Customs interrogation, these rights attach when the questioning has ceased to be purely investigatory and has become accusatory.” Elaborating further, the court explained
[This] has both an objective and subjective element. The objective element[ ] requires that officers provide Miranda warnings when there exists probable cause to make an arrest.... The subjective element requires that officers provide Miranda warnings when it is аpparent that the interrogating officer’s purpose in questioning is not purely investigatory.
As applied in the Customs setting:
when the questioning extends beyond that asked of the average Customs interrogee at either primary or secondary inspection, we infer that the interrogation has become sufficiently focused upon the interrogee to require Miranda warnings.
Applying the facts to these legal standards, the court concluded that the “interrogation turned accusatorial at the time Inspector Fisher asked Cedeno whether she was carrying any money.” At that point, the “investigation had clearly narrowed to a particular crime with particular defendants, based on what we infer to have been substantial, particularized suspicions.” Accordingly, the court determinеd, all ensuing statements violated Miranda, and were properly suppressed.
DISCUSSION
The government claims that the court’s test for a
Miranda
violation was legally erroneous. Defendants concede that the court’s approach was novel, but argue that, taken as a whole, it comports with settled precedent. Our task in this appeal is straightfоrward: to set forth the
Miranda
test as derived from Supreme Court and First Circuit caselaw and assess whether the district court followed it. Our standard of review is
de novo. See United States v. Lewis,
Miranda
warnings must be given before a suspect is subjected to custodial interrogation.
United States v. Taylor,
The custody determination is the initial and, generally, the central inquiry: it is “the touchstone to the need for
Miranda
warnings.”
United States v. Quinn,
*711
In order to assess the “restraint on freedom of movement,” a court must examine all the circumstances surrounding the interrogation. This test is objective: the only relevant inquiry is “how a reasonable man in the suspect’s shoes would have understood his situation.”
2
Stansbury,
511 U.S. at -,
Relevant circumstances include “whether the suspect was questioned in familiar or at least neutral surroundings, the number of law enforcement officers present at the scene, the degree of physical restraint placed upon the suspect, and the duration and character of the interrogation.”
United States v. Masse,
Determining what constitutes custody can be a “slippery” task.
See Oregon v. Elstad,
In
Pratt,
we made clear that even secondary inspection does not
per se
constitute custodial interrogation. We acknowledged that though “[a]ny person required to submit to a secondary customs search may apprehend some increased level of official suspiсion[,] ... this perception ... is not sufficient by itself to apply coercive pressures equivalent to custodial questioning.”
The other component of custodial interrogation is, of course, interrogation. Interrogation refers to both express questioning and its “functional equivalent,” which includes “any words or actions on the part of the police (other than those normally attendant to arrest and custody) that the police should know are reasonably likely to elicit аn incriminating response from the suspect.”
Rhode Island v. Innis,
In summary,
Miranda
warnings ensure that an individual subject to custodial interrogation has a “full opportunity to exercise the privilege against self-incrimination.”
Miranda,
We will not dwell on all the problems in the district court’s version of the Miranda inquiry, but point out a few significant errors. First, the court toоk the ultimate factual and legal question — were defendants in custody? — and treated it in a per se manner: because travelers “may not simply walk away from an interrogating officer,” they are in custody. This is simply wrong. Individuals subject to routine traffic stops or customs insрections, circumstances which are not custodial, are rarely free to leave while being questioned by an officer. The relevant inquiry, however, as stated above, is whether there was an arrest or restraint on freedom of movement of the degree associated with a formal arrest.
The court’s further assertion that “all reasonable people would agree that Customs is an inherently custodial setting, regardless of the circumstances of the interrogation,” is directly contrary to our decisions in
Tajeddini
and
Pratt
and runs counter to the proper approach articulated by the Supreme Court. A custody determination requires inquiry into
all
circumstances surrounding the interrogation.
See Keohane,
— U.S. at - & n. 11,
Finally, we note that the court, relying on outmoded circuit opinions, discussed certain factors, such as whether there was probable cause to make an arrest and the officers’ focus on the defendants, which are not relevant to a
Miranda
inquiry. At one time, certain courts found these factors relevant,
see, e.g., United States v. Henry,
Defendants argue that the court’s test, taken as a whole, is consistent with our precedеnt. We disagree. Although there may be tests which, though formulated differently, approximate the proper standard, this is not one of them. Accordingly, we remand this case to the district court for application of the correct legal test. On remand, the court may take additional evidence on the relevant factual issues.
See Streifel,
The order suppressing evidence is vacated. We remand to the district court for proceedings consistent with this opinion.
Notes
. This specific formulation was first articulated in
California v. Beheler,
. In
Keohane,
the Court made clear that the ultimate determination of custody is a mixed question of fact and law. The initial examination of the “totality of the circumstances” is factual. The second inquiry, however — whether, objectively, these circumstances constitute the requisite “restraint on freedom of movement of the degree associated with a formal arrest” — requires the “application of the controlling legal standard to the historical facts.” - U.S. at - & n. 11,
. This is not an exhaustive list. Other courts have identified other factors significant to a custody determination.
See Sprosty v. Buchler,
. However, an officer's knowledge " 'concerning the unusual susceptibility of a defendant to a particular form of persuasion might be an important factor in determining' what the [officer] reasonably should have known.”
Pennsylvania
*712
v. Muniz,
. We note that not all questioning of in-custody suspects constitutes interrogation triggering the
Miranda
protections. For example, many courts recognize a “routine booking interrogation” exception to the
Miranda
rule.
