OPINION
Scott Raymond Shetler (“Shetler”) appeals from his conviction for maintaining his residence “for the purpose of manufacturing, distributing, or using” methamphetamine in violation of 21 U.S.C. § 856(a)(1). Shetler contends that the district court erred in denying his motion to suppress certain inculpatory statements he made to Drug Enforcement Agency (DEA) officials. Because the government did not bear its burden of showing that these statements were not the product of government officials’ concededly illegal searches of Shetler’s home and garage, we reverse his conviction. Shetler further contends that there was insufficient evidence to support his conviction, and that the statute is void for vagueness as applied to him. We conclude that, although the evidence was sparse, it was sufficient to allow a jury to infer that one of the primary or principal uses to which Shetler devoted his property was the manufacture, distribution, or use of methamphetamine. We therefore hold that he is not entitled to a judgment of acquittal on the ground of insufficient evidence. We also reject his void for vagueness argument.
I.
1. Factual Background
At 7:40 p.m. on September 22, 2009, an anonymous tipster later revealed to be Jamie Shetler (“Jamie”) called the Pomona Police Department to report that her father, Shetler, was manufacturing and using methamphetamine in his home in Pomona, California. Three police officers arrived at Shetler’s home shortly after 8 p.m. Shetler’s house has an attached garage. As the officers approached Shetler’s house, they noticed that the door to the garage was open, and one officer smelled a chemical odor associated with possible methamphetamine production emanating from within. The officers observed that the garage was full of boxes, *1154 motorcycle parts, and other equipment. They also saw a partition wall that concealed the back portion of the garage from their view.
The officers entered the garage and conducted a visual sweep to determine if there was an in-operation methamphetamine lab or a person behind the partition wall. They did not find anyone inside the garage or any evidence that methamphetamine was then being cooked. The officers did, however, observe the following items in plain view behind the partition wall: a can of acetone, a duffel bag containing several plastic and glass beakers, and a jug that appeared to contain red phosphorus, a chemical that the officers knew to be related to the production of methamphetamine.
At approximately 8.T5 p.m., the officers left the garage and knocked on the front door of the house. Shetler exited the house from a side door and approached the officers, who handcuffed and detained him. By this point, several additional police officers had arrived. The police then called into the house to Shetler’s girlfriend, Cynthia Marohn, and her daughter, both of whom lived with Shetler. Marohn and her daughter stepped outside, and several officers immediately entered the residence and conducted a sweep. After completing this search of the house, several officers stayed inside the house, near the front door and in view of Marohn, who remained outside. At 8:45 p.m., while these officers were still inside the residence, Marohn signed a consent form that authorized the police to enter the premises and search for “methamphetamine, methamphetamine cooking and packaging material, [and] weapons.”
The police then began to search Shetler’s home and garage. By 9 p.m., DEA agents had arrived. They put on protective suits and masks and performed a more thorough search of Shetler’s garage than the police had previously conducted. By midnight, they had uncovered a number of items associated with methamphetamine production, including acetone, iodine and iodine pellets, hydriatic acid, muriatic acid, Drano, Heet, flasks with residue, empty bottles of lighter fluid, a water bottle with white residue, a yellow bi-layered liquid, a red powder they suspected to be ground up pseudoephedrine, and a hot plate. Inside the house, the police recovered a number of firearms, along with additional items consistent with methamphetamine use.
During this entire period, Shetler was detained outside of his house in view of the extensive ongoing searches. At 1:30 a.m. on September 23rd, a DEA agent read Shetler his Miranda rights. Shetler then confessed to the agent that he had been manufacturing methamphetamine in a laboratory in his garage.
Shetler was taken to the Pomona Police Department, where he was held until September 24th. At 10 a.m. that morning, a DEA agent took custody of Shetler. After reading him his Miranda rights, the agent drove him to his home and interrogated him regarding an additional firearm that he suspected had not yet been recovered. Shetler told the agent that he had a handgun hidden in a tool box in the back of his garage, and signed a consent form to allow the agent to enter the garage and recover the gun. The agent then transported Shetler to a DEA field office.
At 1 p.m., Shetler was again read his Miranda rights. Four DEA agents, including Agent Bradley Clemmer, then interviewed him. During this interview, Shetler made multiple statements regarding his methamphetamine use and production, along with statements regarding the firearms and ammunition in his possession. Shetler had not, at the time he gave these statements, had any contact with a lawyer, *1155 and had been continuously in detention since the time of his arrest.
2. Procedural History
Shetler was charged with maintaining drug-involved premises in violation of 21 U.S.C. § 856(a)(1) and knowingly possessing a firearm in furtherance of a drug trafficking crime in violation of 18 U.S.C. § 924(c)(l)(A)(i). Prior to trial, he moved to suppress all evidence obtained during the warrantless searches of his house and garage on the night of his arrest, the additional handgun found on September 24th, and all statements he had made on the night of his arrest and during his interview at the DEA office.
After conducting two separate evidentiary hearings, the district court held that the initial warrantless sweep of the garage had been justified under the exigent circumstances, emergency, and protective sweep exceptions to the Fourth Amendment, and that the evidence observed during that sweep — the can of acetone, the duffel bag containing several beakers, and the jug of red phosphorus — need not be suppressed. It found, however, that the initial warrant-less sweep of the house could not be justified under any of the exceptions applicable to the initial search of the garage, and was therefore illegal. The court further found that Marohn’s consent to any further searches was tainted because the police sought her consent while officers remained physically inside the house after having already illegally searched it. All subsequent searches on the night of the 22nd were therefore deemed to be illegal, and all evidence obtained during the course of those searches was suppressed. Also suppressed as the fruit of those illegal searches was the additional firearm recovered by the DEA agent on the morning of the 24th, along with any statements Shetler had made relating to his possession of firearms. 1 The district court denied, however, Shetler’s motion to suppress the statements relating to his methamphetamine use and manufacture he had made to DEA agents on the night of his arrest and during the interview at the DEA office. It held that those statements need not be suppressed because they were “sufficiently the product of the initial legal search of the garage, and the Defendant’s lawful arrest for methamphetamine manufacture thereon, and were not tainted by the illegal searches of the garage.”
At trial, the government introduced, through the testimony of Agent Clemmer, the statements Shetler had made at the DEA office. Clemmer testified that Shetler had admitted to manufacturing methamphetamine using a recipe he had obtained on the internet. He described the procedure of cooking and mixing the various chemicals that Shetler claimed to use, as well as how Shetler would go to multiple small pharmacies that would not require him to show identification in order to attain pseudoephedrine, a necessary component of methamphetamine. Clemmer also testified that Shetler had admitted that both he and Marohn consumed the methamphetamine he manufactured, that he would use the drug five times a week, two to three times a day, and that he had begun to use it in 1989. Clemmer could not recall the exact date that Shetler claimed to have begun manufacturing methamphetamine, but Clemmer believed he had said that it was five years before his arrest.
*1156 The government presented three witnesses in addition to Agent Clemmer. The first, Pomona police officer James Suess, described the police’s initial search of Shetler’s garage and the items they had observed behind the partition wall. The second, DEA Chemist Helene Jennsen, described the process of manufacturing methamphetamine, and testified that she had tested two of the chemicals found in Shetler’s garage and determined them to be chemicals often used in this process.
The final government witness was Shetler’s daughter, Jamie. Jamie, who had lived in her father’s house “off and on” during the prior four years, testified that: (1) Shetler spent a great deal of his time in the partitioned area of the garage; (2) while “snoop[ing] around” in that area, she had seen beakers containing fluids, a hot plate, and funnels; (3) she had on a number of occasions smelled a strong chemical odor emanating from the garage; (4) she had found a recipe for making methamphetamine on her father’s computer, witnessed him take a large box of matches and remove all the tips, and had heard him describe going to different stores in different cities in order to buy Sudafed (which contains pseudoephedrine); (5) she had seen pipes in the armoire in Shetler’s bedroom, and had often heard the flick of a cigarette lighter and coughing when Marohn and Shetler were in that room; and (6) “oftentimes” Shetler would host people in the garage; she described one night in particular on which there had been a number of cars parked in the driveway, the doors to the garage were shut, and it “sounded like a party was going on” inside.
At the close of trial, Shetler made a motion for acquittal, contending that there was insufficient evidence to sustain his conviction under 21 U.S.C. § 856(a)(1), and that the statute would be void for vagueness if applied to him. The district court denied the motion. After the jury returned a guilty verdict, Shetler made a motion for new trial or acquittal, renewing his objections that there was insufficient evidence to sustain his conviction and that the statute as applied to him was void for vagueness. The district court denied this motion as well. Shetler now appeals.
II.
Shetler argues, first, that the district court erred in denying his motion to suppress the statements regarding his drug activities that he made to a DEA agent on the night of his arrest outside his home and those he made during his interview at the DEA office 36 hours after his arrest.
2
We review de novo the district court’s denial of Shetler’s motion to suppress these statements, and review factual findings underlying the denial of the motion for clear error.
United States v. Bynum,
The exclusionary rule bars the prosecution from using at trial evidence that has been obtained through a violation of the Fourth Amendment.
Wong Sun v. United States,
Neither party before this Court challenges the district court’s determinations that the initial search of Shetler’s garage was legal, but that all subsequent searches of Shetler’s home and garage— conducted without a warrant, without valid consent, and without any justificatory extenuating circumstances — were illegal. The question, then, is whether the district court erred in finding that the statements made by Shetler at the DEA office were not sufficiently connected to the preceding illegal searches to constitute “fruit of the poisonous tree.” We first ask whether the statements were the product of the illegal searches; if they were, we then ask whether they were nevertheless so attenuated from the searches that suppression was not warranted.
See New York v. Harris,
The government did not bear its burden of showing that Shetler’s statements were not the product of the illegal searches. Contrary to the district court’s determination, there is no evidence in the record to support the conclusion that the statements were “the product of the initial legal search of the garage, ... and were not tainted by the illegal searches of the garage.” Both the district court and the government appear to presume that the relevant inquiry is whether the agents could have questioned Shetler regarding his drug activities but for the illegal search. The logic underlying this position is as follows: because the government had probable cause, regardless of any evidence revealed during the illegal searches of his house and garage, to arrest and question Shetler as to whether he used or manufactured methamphetamine, the statements he made during that questioning cannot be considered the product of the illegal searches.
Although the presence of probable cause may generally be the “dispositive” issue in determining whether a confession stemming from an illegal
detention
should be suppressed,
see Crawford,
*1158
The first additional consideration in an illegal search case is that the interrogating officers may confront the suspect, either physically or verbally, with the evidence that has been illegally obtained.
See Ruiz v. Craven,
A second, related, consideration in an illegal search case such as this is that the answers the suspect gives to officials questioning him may be influenced by his knowledge that the officials had already seized certain evidence. “Confronting a suspect with illegally seized evidence tends to induce a confession by demonstrating the futility of remaining silent.” 6 Wayne R. LaFave, Search and Seizure 307, § 11.4(c) (4th ed. 2004) (quoting
People v. Robbins,
Nor has the government borne its burden of showing that, if Shetler’s statements were the product of the illegal searches of his home and garage, they were nevertheless sufficiently attenuated from the government’s illegal conduct so as not to warrant suppression. “Challenged evidence is not considered the fruit of lawless police conduct when the connection between the illegality and the evidence becomes ‘so attenuated as to dissipate the taint.’ ”
United States v. $186,416.00 in United States Currency,
Although the 36 hours that passed between the illegal search and Shetler’s confession at the DEA office is a relatively long time, the temporal proximity factor does not weigh in the government’s favor. The relevant question for attenuation purposes is whether this passage of time would have in any way dissipated Shetler’s perception that the searches had produced evidence such that his remaining silent would be useless, or decreased the extent to which the government’s confronting Shetler with the illegally seized evidence induced his statements. “[T]o draw any conclusions from [the] timing of [the defendant’s] confessions, we must consider the temporal proximity factor in conjunction with the presence of intervening circumstances.”
United States v. Reed,
There are likewise no intervening circumstances that break the causal chain between the searches and the confession. Shetler spent the intervening period in detention, and did not speak to a lawyer. Although Shetler did receive
Miranda
warnings on at least three occasions after the illegal searches and before his confession in the DEA office, such warnings are insufficient to “purge the taint of a temporally proximate prior illegal” act.
United States v. Washington,
Finally, the government has not shown that the third attenuation factor, the purpose and flagrancy of the illegal search, weighs against suppression of Shetler’s statements. A statement is more likely to be tainted if there is evidence that the illegal conduct that preceded it involved “either purposeful extraction of evidence or flagrant illegality.”
Washington,
We hold that the government did not bear its burden of proving that Shetler’s statements to DEA officials were not the product of the illegal searches of his home and garage, and that the district court therefore erred in denying Shetler’s motion to suppress these statements. The government does not contend that the ad
*1161
mission of the statements at trial through the testimony of Agent Clemmer was harmless beyond a reasonable doubt.
See Bishop,
III.
We now consider Shetler’s claims that, if successful, would entitle him to a judgment of acquittal.
See United States v. Williams,
1. 21 U.S.C. § 856(a)(1)
Under § 856(a)(1), which is also known as the federal “crack-house” statute,
see United States v. Verners,
knowingly open, lease, rent, use, or maintain any place, whether permanently or temporarily, for the purpose of manufacturing, distributing, or using any controlled substance.
21 U.S.C. § 856(a)(1).
Shetler’s challenge to his conviction turns in large part on the meaning of the phrase “for the purpose of’ in § 856(a)(1). Although some circuits have attempted to define the requisite type and degree of purpose connecting a defendant’s use of property and his drug activities under § 856(a)(1), we have not yet directly confronted the issue. Courts to consider the question have agreed that § 856(a)(1) does not apply to occasional drug use in one’s own home. As the D.C. Circuit has held, “The ‘casual’ drug user does not run afoul of [§ 856(a)(1) ] because he does not maintain his house for the purpose of using drugs but rather for the purpose of residence, the consumption of drugs therein being merely incidental to that purpose.”
United States v. Lancaster,
To the extent that there is a meaningful difference between these various formulations, we agree with the Tenth Circuit that “in the residential context, the manufacture (or distribution or use) of drugs must be at least one of the primary or principal uses to which the house is put.”
Id.
Restricting the application of § 856(a)(1) to those individuals whose manufacture, distribution, or use of drugs in their residence constitutes “one of the primary or principle” purposes of their occupancy of that residence ensures that the statute does not extend beyond its intended coverage so as to encompass “incidental” drug use,
see Lancaster,
Shetler contends that § 856(a)(1) should be interpreted to apply only to those who use their property for
commercial
drug activities. Although his argument is not unreasonable, we do not read the statute so narrowly. Nothing in the text of the statute limits its application to commercial drug sales. Nor does the statute’s place within the federal drug laws provide support for Shetler’s construction. Although Shetler is correct that other statutes already criminalize possession and manufacture of a controlled substance, a commercial purpose requirement is not necessary to save § 856(a)(1) from redundancy: in contrast to other federal drug laws, § 856(a)(1) is designed to proscribe particular “use[s] of
property
” to further drug activities.
United States v. Stunnoski,
That said, Shetler is correct that Congress’s primary purpose in enacting § 856(a)(1) was to target those who use their property to profit from drug sales. As then-Senator Joe Biden explained after the enactment of the 2003 amendment to § 856, which he authored, the statute “does not criminalize simple consumption of drugs in one’s home.” 149 Cong. Rec. S10608 (daily ed. July 31, 2003);
see Lancaster,
[T]he “crack-house” statute was designed to punish those who use their property to run drug businesses — hence, *1163 the more characteristics of a business that are present, the more likely it is that the property is being used “for the purpose of’ those drug activities prohibited by § 856(a)(1).
Verners,
2. Sufficiency of the Evidence
We review de novo Shetler’s appeal from the district court’s denial of his motion for acquittal.
United States v. Sullivan,
Although it is a close question, we conclude that the prosecution presented sufficient evidence to permit the jury to infer that one of the primary or principal uses to which Shetler put his property was the manufacture, distribution or use of methamphetamine for a purpose other than consumption by himself and those who shared his home. There was undisputed evidence that Shetler regularly manufactured methamphetamine, and that he often hosted gatherings in his garage. Because the gatherings were held in a garage in which methamphetamine was being manufactured, and because the garage was closed during the gatherings, the jury could have inferred that methamphetamine that Shetler manufactured was consumed at the gatherings.
See Cavazos v. Smith,
*1164
— U.S. -, -,
3. Void for Vagueness
Whether a statute is void for vagueness is reviewed de novo.
United States v. Mincoff,
Shetler contends that § 856(a)(1) does not “give a person of ordinary intelligence a reasonable opportunity to know” that it would apply to the sort of drug manufacture, distribution, and use in which he engaged. Although he is correct to point out that the line drawn to determine the boundaries of the statute if construed broadly would be hazy, it is not unconstitutionally vague if narrowly construed.
See Grayned v. City of Rockford,
IV.
We hold that the district court erred in denying Shetler’s motion to suppress the statements he made to DEA agents regarding his drug activities. We affirm, however, the district court’s denial of Shetler’s motions for acquittal and new trial on the grounds that there was insufficient evidence to sustain his conviction under § 856(a)(1) and that the statute was void for vagueness as applied to him. Accordingly, we reverse Shetler’s conviction, and remand for further proceedings consistent with this opinion.
REVERSED and REMANDED.
Notes
. The district court subsequently dismissed the gun possession charge on the govern-merit's motion at trial.
. Although the district court did not suppress either set of statements, the Government introduced at trial only those statements that Shetler made at the DEA office, not those he made while outside his home on the night of the arrest. We consider, therefore, only whether the district court erred in failing to suppress this former set of statements, as any error with respect to the latter was harmless beyond a reasonable doubt.
See United States v. Bishop,
. The government attempts to analogize this case to
United States v. Green,
. In contrast, in the absence of a deliberate law enforcement decision to conduct an un
Mirandized
interrogation in advance of one with
Miranda
warnings,
see Missouri v. Seibert,
. As the prosecutor emphasized in his closing argument, “[M]ost importantly, ladies and gentlemen, the defendant confessed. He confessed.”
. Because we hold that the failure to suppress Shetler's confession in the DEA office was reversible error, we need not reach Shetler’s claim that aspects of the jury instructions given by the district court were erroneous.
. In
United States v. Basinger,
we upheld a defendant’s conviction under § 856(a)(1) based on evidence showing that he used a shed located on someone else’s property as a clandestine methamphetamine laboratory.
. At the time
Claris
was decided, § 856(a)(1) made it illegal to " 'knowingly maintain or open any place for the purpose of manufacturing, distributing, or using any controlled substance.' ”
