A federal grand jury in the District of Maine indicted Carlos Esquilin on a charge of possession of cocaine with intent to distribute in violation of 21 U.S.C. § 841(a)(1). After the district court denied Esquilin’s motion to suppress physical evidence seized in a search of his motel room and statements he made to the police after his arrest,
see United States v. Esquilin,
I.
On September 17, 1998, Esquilin was staying at the Super 8 Motel in West-brook, Maine. The motel manager suspected possible drug activity in Esquiliris room because there were a large number of telephone calls and visitors to the room and because Esquilin had re-rented the room in his name and that of Martin Wright after the room had originally been rented, and paid for in cash, by Wright alone. The manager telephoned Detective Kenneth Viger of the Westbrook Police to explain her suspicions. Knowing that the manager had been a reliable informant regarding drug activity in the past, Viger went to the motel accompanied by Officer Philip Hebert and Hebert’s drug-sniffing German shepherd, Zena. In the motel hallway, in response to Hebert’s command to *317 find drugs, Zena went to Esquilin’s door and sniffed deeply. The officers knocked at the door and Esquilin answered; a smell of marijuana emanated from the room.
Esquilin consented to the officers and the dog entering his room so that Viger could ask him some questions. 1 Viger told Esquilin that he was there to investigate suspected drug activity and asked Esquilin about the reasons for his trip to Maine. Although Viger and Hebert gave conflicting testimony at the suppression hearing about what Hebert and Zena were doing while Viger and Esquilin conversed, the district court accepted Hebert’s testimony that Zena was sniffing throughout the motel room while Hebert held her on a six-foot leash. See id. at 25. She sniffed at all the furniture, especially the bed, at a GAP shopping bag in the corner of the room, and at Esquilin himself, who patted her playfully and said he had a dog of his own, leading the officers to believe that he was trying to distract her. Esquilin appeared extremely nervous, his hands were shaking, and he gave evasive replies to Viger’s questions.
Believing that Zena had sensed the presence of drugs in the room, Hebert communicated this to Viger by nodding to him. Viger asked Esquilin if he had' any drugs; when Esquilin said he did not, Viger asked if Esquilin minded if they looked around to make sure. Esquilin responded, “No, go ahead, look anywhere you want.” Hebert gave Zena the command to “find the dope,” and she immediately returned to the GAP bag. After pulling out some clothing, she pulled out a plastic bag containing white powder and, according to Hebert, “threw it in the air, [and it] did the somersault and fell in the middle of the floor.” Viger asked Esquilin what was in the bag. He answered, “coke.”
Esquilin was arrested and Viger went to the manager’s office to telephone for backup. After the arrest, Viger and Hebert neither questioned Esquilin nor gave him Miranda warnings. Agent Gerard Brady of the Maine Drug Enforcement Agency arrived and took over the investigation. Viger told Brady that no Miranda warnings had been given to Esquilin. Brady asked Esquilin why he was there and what was going on. Esquilin gestured at the plastic bag and said, “Because of cocaine.” In response to questions from Brady, Es-quilin said that he was from New York, that the bag contained nine ounces of cocaine, and that the cocaine was his. Es-quilin’s pager went off, prompting Brady to ask Esquilin if he minded if he looked at the telephone number that was displayed. Esquilin indicated that he did not; when asked he said that the number was his girlfriend’s. Brady then read Esquilin the Miranda warnings from a preprinted card. After each warning Esquilin said he understood his rights, and both Brady and Esquilin signed the card. Brady asked if Esquilin wanted to speak to him then, without a lawyer present, and Esquilin answered, “I’ll talk to you man to man.” He then made a detailed confession, explaining that he had purchased the cocaine in the Bronx for $6,000 and brought it to Maine to sell.
In the district court Esquilin sought suppression of all the physical evidence discovered in the motel room, including the cocaine, some cash that was discovered under a mattress, and a piece of paper found in his clothing. He also sought to suppress all of the statements he made to police before and after the Miranda warnings. The government did not seek admission of the piece of paper or Esquilin’s pre-warning statements to Brady. The court refused to suppress the other evidence, and Esquilin preserved the issue for ap *318 peal by entering a conditional guilty plea pursuant to Fed.R.Crim.P. 11(a)(2).
II.
On appeal, Esquilin first contends that the district court erred by finding that-the dog sniff inside the motel room was not a search and that his subsequent consent to search the room was voluntary. Both contentions are without merit.
While Viger was conversing with Esquilin, Zena sniffed around the motel room while held on a six-foot leash by Hebert. The court ruled that this sniffing behavior was not a search, relying on
United States v. Place,
Esquilin argues further that his consent to the full-blown search of the motel room, in which Zena found and retrieved the cocaine, was not voluntary. We review the district court’s finding that Esquilin’s consent was voluntary for clear error.
See United States v. Coraine,
Esquilin expressly consented to the search, and the evidence amply supports the district court’s finding that the consent was voluntary. On appeal, Esquilin points to no facts that suggest a contrary conclusion. So far as the record reveals, his extreme nervousness, rather than the result of any coercive conduct by Viger or Hebert, was merely the natural reaction of a person who has inartfully hidden cocaine in his motel room and is faced with an unexpected visit from two policemen and a drug-sniffing dog. The district court did not err in refusing to suppress the physical evidence discovered in the search.
III.
Esquilin contends that the district court erred by refusing to suppress the statements he made to Agent Brady after Brady administered the Miranda warnings. The admission of Esquilin’s pre-warning statement to Brady was. .not at issue. 3 Conceding that that statement was obtained in violation of Miranda, the govern *319 ment did not seek to introduce it in evidence.
When a defendant’s initial statement is obtained in violation of
Miranda,
the admissibility of a subsequent statement made after
Miranda
warnings is governed by
Oregon v. Elstad,
Esquilin does not argue on appeal that his first statement was involuntary or that the subsequent
Miranda
warnings he received were deficient. Thus,
Elstad
would appear to dictate the admissibility of his post-warning statement. Esquilin nevertheless argues that
Elstad
is distinguishable because it involved two temporally separate interrogations (about an hour apart,
see
According to
Elstad,
the lapse of time between interrogations is relevant only when the statement obtained in violation of
Miranda
was actually coerced.
See id.
at 310-11,
Esquilin also argues that his first, unwarned statement was the product of “improper tactics.” In
Elstad,
the Court observed that “absent deliberately coercive or improper tactics in Obtaining the initial statement, the mere fact that a suspect has made an unwarned admission does not warrant a presumption of compulsion”
4
as to the subsequent statement.
*320
Id.
at 314,
This argument focuses on some admittedly imprecise language in
Elstad
while ignoring the Court’s emphasis on volun-tariness throughout the opinion. Although the Court did not explicitly define “deliberately coercive or improper tactics,” it used several more detailed phrases that in context are synonymous with that term: “actual coercion or other circumstances calculated to undermine the suspect’s ability to exercise his free will,”
id.
at 309,
Esquilin cites no cases adopting a contrary interpretation of “improper tactics.” His broader contention that a deliberate failure to give
Miranda
warnings can mandate the suppression of a post-warning confession despite the voluntariness of both statements is supported by language in one circuit case,
United States v. Carter,
Esquilin does not contend that Brady’s allegedly deliberate
Miranda
violation
*321
made his first statement involuntary, and he could not reasonably do so. It is part and parcel of the
Elstad
holding that a failure to give
Miranda
warnings does not, without more, make a confession involuntary.
See Elstad,
Finally, Esquilin suggests that the deterrence rationale of the
Miranda
rule would be undercut if a deliberate violation by Brady did not result in the suppression of Esquilin’s confession, even going so far as to claim that
“Elstad
could not apply to the present situation without implicitly overruling
Miranda.”
We disagree. Although
Elstad
does not permit suppression of Esquilin’s voluntary statement made after he was informed of his
Miranda
rights and voluntarily waived them, the basic
Miranda
rule still operates here to render Esquilin’s initial, unwarned (but voluntary) statement inadmissible. The Supreme Court has judged that
Miranda’s
deterrence rationale requires no more than that,
see Elstad,
The district court carefully considered these issues and correctly determined that Esquilin’s unwarned admissions to Brady were not rendered involuntary by “deliberately coercive or improper tactics.” Because Brady’s “careful and thorough administration of
Miranda
warnings serve[d] to cure the condition that rendered the unwarned statement inadmissible,”
id.
at 311,
Affirmed.
Notes
. Esquilin argued before the district court that he did not voluntarily consent, at least to the entry of the dog. The court concluded that "Mr. Esquilin voluntarily consented to the officers and the drug-detection dog entering his motel room,”
. Esquilin also says that a search occurred when Zena moved various items, particularly the shopping bag, during her initial sniffing around the room. We need not address the legal theory behind this contention, raised for the first time on appeal, because the record is devoid of evidence that Zena moved anything until after Esquilin consented to a full-scale search.
. Esquilin does not argue that the statements he made to Viger before he was arrested, including his admission that the plastic bag contained "coke,” should have been suppressed pursuant to Miranda.
. The
Elstad
Court used the term "presumption of compulsion” (and, equivalently, "presumption of coercion”) in two distinct ways. When a statement is obtained in violation of
*320
Miranda
there arises a presumption of compulsion
as to that statement. See
. The district court did not make a finding that Brady’s
Miranda
violation was deliberate. Instead, the court stated that "to the extent [Brady’s] conduct is a deliberate or an oft-repeated strategy, it is an unwise one.”
