The government appeals the district court’s 1 suppression of fingerprint evidence obtained as the result of an unlawful arrest and detention. We affirm.
BACKGROUND
On January 31, 2000, two Omaha police officers stopped a car in which Martin Guevara-Martinez was a passenger. The officers found methamphetamine in the car and placed Guevara-Martinez under arrest. During the course of the stop, an officer asked Guevara-Martinez for his name. Initially, Guevara-Martinez did not respond at all; he later told the officer that he had no identification. In fact, Guevara-Martinez had identification. The officer removed an ID from Guevara-Martinez’s wallet, and determined that it did not match Guevara-Martinez’s appearance.
The officers transported Guevara-Martinez to the Omaha jail. Suspecting that he might be an illegal alien, the officers informed a special agent of the United States Immigration and Naturalization Service (INS) of the arrest. The agent went to the jail to interview Guevara-Martinez. Guevara-Martinez gave the agent the false name of Jose Diaz-Ibarra, and admitted that he did not have permission to be in the United States.
On the day following the arrest, after the INS interview, Omaha police took Guevera-Martinez’s fingerprints. Nothing in the record shows that Guevara-Martinez consented to the fingerprinting. Ultimately, the fingerprints revealed Guevara-Martinez’s true identity, which linked him to his INS file. His INS file indicated that he had previously been deported from the United States.
On February 24, 2000, Guevara-Martinez was indicted for possession with intent to deliver methamphetamine. That charge was later dismissed, however, because the district court ruled that the January 31 traffic stop was illegal, and suppressed the drugs seized during the stop. The government did not appeal the district court’s ruling that the traffic stop was illegal.
On June 22, 2000, seven days aftér the government dismissed the drug charge, Guevara-Martinez was indicted a second time, this time for being an illegal alien found in the United States after deportation, in violation of 8 U.S.C. § 1326. Guevara-Martinez again moved to suppress all evidence flowing from the illegal traffic stop, particularly his fingerprints and the statements he made about his identity. Alternatively, Guevara-Martinez moved for dismissal on the grounds that the government had an improper motive for the second prosecution (i.e., retaliation for having to dismiss the drug charge).
The government opposed the suppression motion. The government relied upon the Supreme Court’s statement that the “body or identity of a defendant or respondent in a criminal or civil proceeding is never itself suppressible as a fruit of an unlawful arrest, even if it is conceded that an unlawful arrest, search, or interrogation occurred,”
INS v. Lopez-Mendoza,
Distinguishing Lopez-Mendoza, the district court suppressed both the fingerprint evidence and the statements Guevara-Martinez made about his identity. 2 The government filed this interlocutory appeal pursuant to 18 U.S.C. § 3731, challenging only the suppression of the fingerprint evidence.
DISCUSSION
When a district court grants a motion to suppress evidence, we review its findings of fact for clear error, and its conclusions of law de novo.
United States v. Wells,
1. Lopez-Mendoza
In
Lopez-Mendoza,
the Supreme Court reviewed two civil cases, both involving deportation proceedings that took place following unlawful arrests. Adan Lopez-Mendoza challenged an immigration court’s jurisdiction over his person following his unlawful arrest, but did not object to the admission of evidence offered against him in the proceeding.
In the jurisdictional case (Lopez-Mendoza), the Court said that the “body or identity of a defendant or respondent in a criminal or civil proceeding is never itself suppressible as a fruit of an unlawful arrest.”
Id.
at 1039,
Notwithstanding the Supreme Court’s different approaches to the jurisdictional and evidentiary challenges brought in
Lopez-Mendoza,
two circuits have applied the Supreme Court’s suppression-of-identity reference to evidentiary challenges in criminal proceedings.
See United States v. Roque-Villanueva,
One court has concluded, however, that Lopez-Mendoza has no bearing upon the suppression of unlawfully obtained identity-related evidence in a criminal proceeding:
[T]he Supreme Court language only addresses the jurisdictional concern that the “body” of the defendant is never suppressible, not whether statements by a defendant regarding his identity may be suppressed. This interpretation is supported by an examination of the authorities cited by the Supreme Court: Gerstein v. Pugh,420 U.S. 103 ,95 S.Ct. 854 ,43 L.Ed.2d 54 (1975) and Frisbie v. Collins,342 U.S. 519 ,72 S.Ct. 509 ,96 L.Ed. 541 (1952). In Frisbie, the Court held that “the power of a court to try a person for crime is not impaired by the fact that he had been brought within the court’s jurisdiction” against his will.342 U.S. at 522 ,72 S.Ct. at 511 . The Supreme Court reaffirmed this holding in Gerstein, stating that an “illegal arrest or detention does not void a subsequent conviction.”420 U.S. at 119 ,95 S.Ct. at 865 . These cases deal with jurisdiction over the person, not evidence of the defendant’s identity illegally obtained. The language in Lopez-Mendoza should only be interpreted to mean that a defendant may be brought before a court on a civil or criminal matter even if the arrest was unlawful.
United States v. Mendoza-Carrillo,
The district court found the reasoning in
Mendoza-Garrillo
more persuasive than the broad interpretation given
Lopez-Mendoza
by the Fifth and Ninth Circuits. So do we. We find it significant that the Supreme Court didn’t distinguish between identity-related evidence and other types of evidence when discussing Sandoval-Sanchez’s evidentiary challenge. The Court simply referred to the “general rule in a criminal proceeding.”
Furthermore, the identity-related evidence that the district court suppressed was fingerprint evidence. Prior to
Lopez-Mendoza,
the Supreme Court twice applied the exclusionary rule to fingerprint evidence obtained as the result of unlawful arrests and detentions.
See Davis,
We conclude that Lopez-Mendoza’s statement about the suppression of identity only refers to jurisdictional challenges, not to fingerprint evidence challenged in a criminal proceeding. Therefore, we must *755 determine whether the “general rule in a criminal proceeding” applies, and if so, whether it requires exclusion of the fingerprint evidence under the circumstances present in this case.
II. Fingerprint Evidence and the Exclusionary Rule
In
Davis,
police officers in Meridian, Mississippi, unlawfully arrested and confined a young black man in order to get his fingerprints and compare them to prints found at the scene of a sexual assault.
The Supreme Court revisited the issue sixteen years later in
Hayes,
which also involved a young black man unlawfully detained by police who wanted his fingerprints.
Since Davis and Hayes both suggest that fingerprint evidence has less Fourth Amendment protection than other types of evidence, those two cases “should not be read as declaring that fingerprints taken after an illegal arrest are always inadmissible.” Wayne R. LaFave, Search and Seizure, § 11.4(g) at 323 (3d ed.1996). But should the exclusionary rule apply to the fingerprint evidence involved in this case? Admittedly, the facts aren’t quite like those in Davis and Hayes, because the police did not detain Guevara-Martinez just to get his fingerprints. But neither were the fingerprints obtained under circumstances the Supreme Court suggested might enjoy less Fourth Amendment protection (i.e., a brief detention in the field unsupported by probable cause).
We reject the government’s contention that
Davis
and
Hayes
are inapposite because the police did not detain Guevara-Martinez for the sole purpose of getting his fingerprints. We apply the exclusionary rule whenever evidence has been obtained “by exploitation” of the primary illegality instead of “by means sufficiently distinguishable to be purged of the primary taint.”
Wong Sun v. United States,
We conclude that officers obtained Guevara-Martinez’s fingerprints by exploiting his unlawful detention, instead of by means sufficient to have purged the taint of the initial illegality. First, we note that Guevara-Martinez did not consent to the fingerprinting. We often find that consent is sufficient to purge the taint of an unlawful detention,
e.g., United States
*756
v. Lyton,
Second, the fingerprints were obtained
during
the unlawful detention, not as the result of a
subsequent
investigation.
Cf. United States v. Watson,
Third, we find it significant that the fingerprinting occurred only after the INS had interviewed Guevara-Martinez. The government has offered no evidence that the fingerprints were obtained as a matter of course through routine booking procedures, rather than for the purpose of assisting the INS investigation.
Cf. People v. McInnis,
A district court decision upon which the government relies,
United States v. Ortiz-Gonzalbo,
Here, the authorities desired to gather the fingerprints, and were able to take advantage of the unlawful detention in order to get the fingerprints. Under these circumstances, we believe that suppressing the fingerprint evidence will achieve a deterrent effect.
As a final, separate matter, the government points out that a set of untainted fingerprints can be obtained in the civil deportation proceedings that Guevara-Martinez will inevitably face. Since Guevara-Martinez can be recharged using the new set of fingerprints, the government asks us to ignore its use of tainted evidence in this case. We decline to reverse the district court on this alternate ground. In
Davis,
the Supreme Court refused to affirm a conviction because the authorities there could have used a second set of prints that were validly obtained, stating that “[t]he important thing is that those administering the criminal law understand that they must [obtain the evidence the right way].”
*757 For the reasons stated, we affirm the district court’s suppression order.
Notes
. The Honorable Joseph F. Bataillon, United States District Judge for the District of Nebraska.
. The district court did not rule on the motion for dismissal.
. Ultimately, the Court found the general criminal rule inapplicable to civil deportation proceedings.
