Wе must decide whether the United States Immigration and Customs Enforcement (ICE) 1 may take custody of a person and fingerprint him without any admissible reason to believe the person is an illegal alien. We conclude that such a custodial detention without justification offends the Fourth Amendment, and therefore, the fingerprints and statements obtained as a result of the detention must be suppressed. We affirm the District Court. 2
I.
Appellant Oscar Flores-Sandoval was taken into custody on July 13, 2003, by *713 local law-enforcement officers in Elk Point, South Dakota. The circumstances of his initial arrest are curiously unavailable and therefore not included in the record. According to Flores-Sandoval’s original motion to suppress, local law-enforcement officers in Elk Point were questioning Florеs-Sandoval, and because he primarily speaks Spanish, the officers called an agent of the United States Border Patrol to act as an interpreter. In the process, Flores-Sandoval allegedly admitted to the Border Patrol agent that he was in the country illegally. There is no indication Flores-Sandoval received a Miranda warning from the police or the Border Patrоl during this custodial encounter. In any event, Flores-Sandoval was placed in the Union County Jail without being chai’ged. Instead, he was the subject of a civil administrative detainer issued by the Border Patrol рursuant to 8 C.F.R. § 287.7 (2005). The Border Patrol then notified ICE Agent Tracy Warner that Flores-Sandoval was being detained as a possible illegal alien. Warner directed ICE detention and removal personnel to transport Flores-Sandoval from the Union County Jail to the ICE office in Sioux Falls, South Dakota. That transportation occurred the next day, after Flores-Sandoval spent the night in jail.
When Flores-Sandoval arrived at the ICE office in Sioux Falls, the setting in the office was relaxed, informal, and others were present, but Flores-Sandoval was still in custody and was not free to leave. Warner scanned electronic fingerprints of Flores-Sandoval’s index fingers using an automated fingerprint identification system. The system searched ICE records to determine if Flores-Sandoval had ever been arrested or deported by the immigration service or had attempted to enter the country illegally. The system indicated that Flores-Sandoval previously had been deported as an alien. After learning this, Warner read Flores-Sandoval his Miranda rights using the Spanish language. Flores-Sandoval then waived his Miranda rights and admitted he previously had been deported. At that point, Warner took a full set of Flores-Sandoval’s fingerprints in ink and retrieved his alien registration file. Flores-Sandoval was subsequently indicted under 8 U.S.C. § 1326(a) (2000) for re-entry after deportation.
Following his indictment, Flores-Sandoval moved to supprеss the statements he made after he was taken into custody by local law-enforcement officers in Elk Point and the statements and fingerprints obtained by Warner, arguing that his detention was illegal and thаt the evidence obtained by Warner was fruit of the poisonous tree. The District Court found that the government had not met its burden to show the initial detention by Elk Point law-enforcement officers was lawful, and therefore, the court held that any evidence obtained as a result of that detention was tainted. Accordingly, the District Court suppressed Flores-Sandoval’s alleged statement to the Border Patrol that he was an illegal alien. Finding no relevant intervening circumstances between Flores-Sandoval’s initial detention and the taking of his fingerprints by ICE, the District Court held that “[tjhere is nothing about sitting in jail thаt sufficiently purges the primary taint of the illegal arrest.” Report and Recommendation of Sept. 14, 2004, at 5 (Simko, J., as adopted by Piersol, C.J.). Consequently, the District Court also suppressed the evidence thereafter obtained by ICE, including Flores-Sandoval’s fingerprints and the admission that he previously had been deported. The government appeals.
II.
In reviewing the District Court’s decision to suppress the evidence, we re
*714
view its findings of fact for clear error and its conclusions of law de novo.
United States v. Guevara-Martinez,
On appeal, the government asserts that ICE’s detention of Flores-Sandoval was constitutional because his admission to being an illegal alien, allegedly made to the Border Patrol, gave ICE a proper basis to detain him pursuant to 8 U.S.C. § 1357(a) (2000). We disagree. “Statements that result from an illegal detention are not admissible.”
United States v. Hernandez-Hernandez,
The two statutory sources the government relies upon for the authority to detain Flores-Sandoval underscore our conclusion that his detention by ICE was not justified. The first is a statute allowing immigration officials to “interrogate any alien or person believed to be an alien as to his right to be or to remain in the United States.” 8 U.S.C. § 1357(a)(1) (2000) (emphasis added). A plain reading of this statute requires the government to show that immigration officials believed Flores-Sandoval was an aliеn before questioning him. Similarly, the second source of authority the government cites is a federal regulation allowing immigration officials to issue a detainer to “seek[ ] custody of an alien рresently in the custody of [another] agency, for the purpose of arresting and removing the alien.” 8 C.F.R. § 287.7(a) (2005). The section of the regulations immediately following the above-quoted section sеts forth “standards for enforcement activities ... [that] must be adhered to by every immigration officer.” Id. § 287.8. Section 287.8 requires that prior to an arrest, an immigration officer must have a “reason to beliеve” the person is an illegal alien. Id. § 287.8(c)(2)(i).
The government has not shown, nor even asserted, that ICE had formed a reason to believe Flores-Sandoval was an illegal alien based on anything other than his initial statement to the Border Patrol admitting he was in the country illegally. Absent that statement, which we again point out was made in circumstances unrevealed by the record and presumably withоut a Miranda warning, the government has demonstrated no evidence to justify detaining him. In other words, because the government has failed to show that the statement was made in circumstances that *715 make its use permissible, we cannot say the government demonstrated a basis for believing Flores-Sandoval was an illegal alien. Consequently, the authority for his full-blown custodial arrest, overnight detention, transportation, and fingerprinting is not to be found in the statute or regulation on which the government relies.
Nor do we find any factual or legal distinction in this case that would permit an outcome different frоm the outcome in
Guevara-Martinez,
which held, in similar circumstances, that fingerprint evidence is subject to the exclusionary rule.
Because the government was able to demonstrate no constitutional justification for detaining Flores-Sandoval, the District Court did not err in granting his motion to suppress his fingerprint evidence and statements.
III.
Following the disposition of this appeal, ICE may issue a detainer to retake custody of Flores-Sandoval because, as a jurisdictional rather than an evidentiary matter, his body and identity cannоt be suppressed as fruit of the poisonous tree.
