Law enforcement executed a search warrant at Brian Thurman's residence after a cooperating informant purchased heroin inside. They discovered drug paraphernalia, two handguns, and a large amount of money. Mr. Thurman was arrested and later charged in a three-count superseding indictment with (1) maintaining a drug-involved premises, in violation of
Before trial, Mr. Thurman filed two motions to suppress: one to exclude self-incriminating statements that he made following his arrest and another to exclude evidence obtained from a search of his cell phone. The district court denied both motions. A jury later convicted Mr. Thurman on the distribution charge, but acquitted him on the drug-premise and firearms charges. The court sentenced him to seventy-two months' imprisonment and four years' supervised release.
Mr. Thurman now challenges the court's denial of his motions to suppress and its findings supporting his sentence. He maintains that he did not waive voluntarily his Miranda rights or consent voluntarily to the search of his cell phone. He also challenges the court's findings at sentencing that he was responsible for at least 700 grams of heroin and that he possessed a dangerous weapon. He notes that the jury convicted him of distributing a significantly smaller quantity of drugs and acquitted him of the firearms charge.
We cannot accept these contentions. Mr. Thurman's suppression arguments require

BACKGROUND
A.
In August 2013, Minnesota police officers tracked the movement of Courtney Williams from the west side of Chicago to Minnesota, where they arrested him with 489 grams of heroin hidden inside a spare tire. Williams told the authorities that Mr. Thurman had supplied him with the heroin in exchange for a $17,000 down payment and $20,000 of debt. Later that month, in cooperation with the police, Williams wore a wire to Mr. Thurman's house in Chicago, where he gave Mr. Thurman $10,000 in partial payment of his debt. Williams continued to cooperate with authorities and arranged a controlled drug purchase the next month. Williams sent Mr. Thurman a text message with the number "150," to which Mr. Thurman wrote "Yeap" and later responded with "Touchdown." 1 The next day, Williams went to Mr. Thurman's house and exchanged $23,500 for 148.5 grams of heroin and the satisfaction of his remaining debt. Law enforcement waited outside while Williams completed the transaction.
After confirming that Williams had purchased heroin inside, the officers forced entry into Mr. Thurman's house and executed a search warrant that was contingent on the completion of the controlled buy. They arrested Mr. Thurman and handcuffed him in the back of a police car. His girlfriend and son remained inside. While searching the basement, the officers found plastic bags, packaging tape, electronic scales, a safe with approximately $27,000 in cash, and some of the money Williams had just exchanged. They did not discover any heroin. Mr. Thurman informed the police that there were two firearms in the house: a Glock .40 caliber handgun in a trash bag in the basement and a Bryco .380 caliber handgun in a bedroom closet upstairs. The officers discovered loaded magazines next to both guns; however, they could not recall consistently whether the guns themselves were loaded. When asked, Mr. Thurman told the officers that they could search the common areas of a nearby residential property which he owned. He refused, however, to sign a consent form and specifically instructed the officers not to search inside the apartments where his tenants lived. An officer wrote "refused to sign but consented" on the consent form. 2
Law enforcement took Mr. Thurman to a Chicago office of the Bureau of Alcohol, Tobacco, Firearms and Explosives ("ATF") for questioning. Once inside the interview room, the agents removed Mr. Thurman's handcuffs and provided him with a Gatorade. According to the authorities, they advised Mr. Thurman of his
Miranda
rights, but he refused to sign an advice-of-rights form. Nevertheless, he indicated a desire to cooperate with them and proceeded to admit that he had sold drugs out of his house and owned two guns
The agents eventually released Mr. Thurman on the understanding that he would return the next day to continue cooperating. They retained his cell phone and expected him to initiate recorded calls with his supplier when he returned. Mr. Thurman asked whether he should bring an attorney with him, and the agents said that it was his choice. Mr. Thurman did not return as expected. Instead, his attorney called to say that Mr. Thurman would not be cooperating any further. Law enforcement subsequently conducted a forensic examination of his cell phone and reconstructed the recently deleted text messages between Mr. Thurman and Williams.
B.
In September 2015, Mr. Thurman was charged in a three-count superseding indictment with (1) knowingly using and maintaining a residence for the purpose of distributing a controlled substance, in violation of
Before trial, he filed a motion to suppress any evidence obtained from the search of his cell phone and a motion to suppress any incriminating statements he made during the post-arrest interrogation. 4 He attached copies of the consent-to-search form for his cell phone and the advice-of-rights form, both of which reflected his refusal to sign. He also submitted an affidavit averring that he "refused to give consent to the requested warrantless searches" and "refused to provide any information to law enforcement agents without the presence of an attorney." 5
The district court held a hearing on the motions. At the hearing, the Government presented substantially consistent testimony from three of the agents involved in Mr. Thurman's arrest and questioning. They all testified that Mr. Thurman refused to sign any forms but verbally agreed to the limited search of his second property, to the search of his cell phone, and to their questioning without an attorney present. The agents did not record their interactions with Mr. Thurman. 6 The defense called two law enforcement witnesses. They provided substantially similar testimony to that of the prosecution's witnesses. Mr. Thurman did not testify at the hearing, instead relying on his affidavit.
The court denied both motions. With respect to the motion to suppress the incriminating
At trial, the Government presented similar testimony from the agents as well as testimony from Williams. It also introduced recordings of Williams's meetings with Mr. Thurman, the drug paraphernalia and handguns seized from Mr. Thurman's residence, Mr. Thurman's incriminating statements following his arrest, telephone records and summaries, and reconstructed text messages and contacts that had been deleted from his cell phone. Mr. Thurman did not testify. The jury convicted him on the distribution charge (Count 2), but acquitted him on the drug-premises charge (Count 1) and the firearms charge (Count 3).
At sentencing, the court found that Mr. Thurman was responsible for distributing between 700 grams and one kilogram of heroin, resulting in a base offense level of 28.
See
U.S.S.G. § 2D1.1(c)(6). It also found that he possessed a dangerous weapon in connection with the drug offense, which triggered a two-level enhancement.
See
U.S.S.G. § 2D1.1(b)(1). Combining his offense level of 30 with his criminal history category of I, the court calculated an advisory guidelines range of 97 to 121 months. The court then considered the sentencing factors under
II
DISCUSSION
A. Motions to Suppress
Mr. Thurman challenges the district court's denials of his motions to suppress. We review the court's legal conclusions de novo and its underlying factual findings for clear error, giving special deference to its credibility determinations.
See
United States v. Burnside
,
1.
We first consider Mr. Thurman's motion to suppress his post-arrest statements.
The law is clear that before law enforcement officers can interrogate a suspect in custody, they must inform the suspect of his
Miranda
rights.
United States v. Shabaz
,
The record adequately supports the district court's finding that Mr. Thurman did not invoke his
Miranda
rights. This finding was based primarily on the court's evaluation of the credibility of the agents compared to that of Mr. Thurman. As is often the case with motions to suppress, the court was faced with "a veritable '[ ]he said' versus 'they said,' "
United States v. Smith
,
We next review whether Mr. Thurman waived his rights and, if so, whether his waiver was voluntary. Waiver can be express or implied.
Berghuis
,
Mr. Thurman maintains that his refusal to sign the advice-of-rights form shows that he did not waive his rights, at least not voluntarily. Refusal to sign a waiver form, however, is not enough to defeat credible evidence of an implied waiver.
See
Smith
,
The circumstances of his interview and his particular conduct closely resemble prior cases in which we have affirmed the voluntariness of defendants' waivers. In
Smith
, we rejected the defendant's argument that her refusal to sign a waiver form required the suppression of her incriminating statements.
See
For all of the reasons above, we affirm the court's denial of Mr. Thurman's motion to suppress his post-arrest statements.
2.
Mr. Thurman also challenges the denial of his motion to suppress evidence resulting from the authorities' search of his cell phone. He again points to his affidavit and his refusal to sign a consent form as evidence that he did not consent, at least not voluntarily, to the search of his phone. He also argues in the alternative that his consent was limited to the search of his phone during the interrogation and did not extend to the subsequent forensic examination. Therefore, he claims, the reconstructed text messages and contacts should not have been admitted at trial.
There is no dispute that "[w]arrantless searches are presumptively unreasonable under the Fourth Amendment."
United States v. Strache
,
Here, the question whether Mr. Thurman consented to the search raises an underlying question: did the officers lie when they testified at the suppression hearing, or did Mr. Thurman lie in his affidavit? This is a classic credibility determination. As such, we "defer to the district court's determination ... because, unlike our review of transcripts, the district court 'had the opportunity to listen to testimony and observe the demeanor of witnesses at the suppression hearing.' "
United States v. Biggs
,
Before addressing the voluntariness and scope of Mr. Thurman's consent, we address two of his arguments that the agents' testimony should not be believed. First, he claims that his refusal to sign the consent form constitutes objective documentary evidence that cannot be disproven by supposedly self-serving testimony. Mr. Thurman's argument over-looks the fact that the agents' testimony does not contradict the documentary evidence: they recalled his refusal to sign the forms
as well as
his separate verbal consent.
10
Furthermore, Mr. Thurman cites no authority for the proposition that documentary evidence necessarily outweighs verbal testimony. To the contrary, we, as well as other courts, have affirmed findings of consent despite a defendant's documented refusal to sign a form.
11
Second, Mr. Thurman highlights
Arguing in the alternative, Mr. Thurman contends that his consent was not given voluntarily. The Fourth Amendment requires that "consent not be coerced, by explicit or implicit means, by implied threat or covert force."
Schneckloth v. Bustamonte
,
When viewed as a whole, the record adequately supports the finding that Mr. Thurman's consent was voluntary. By all accounts, Mr. Thurman is an intelligent and educated person. He graduated from Purdue University and was pursuing a master's degree at the time of his arrest. He was advised of his constitutional rights and consented to the search without repeated prompting. Additionally, there are no indications that physical coercion was used to obtain his consent. Although Mr. Thurman was in custody, his handcuffs were removed and he was given a Gatorade. The fact that he limited his consent to an earlier search and refused to sign the consent form further demonstrates that he was comfortable partially granting, and even denying, the officers' requests.
Mr. Thurman's last challenge to the search concerns the scope of his consent. Even if his consent was freely given, he claims, it did not extend to the secondary forensic search of his phone. 12 Based on the record before us, we cannot agree.
It is well established that a criminal suspect may limit the scope of consent to a search,
see
Mr. Thurman's actions and the circumstances of the investigation adequately support a finding that he consented to the forensic examination. "[C]ourts can look at the defendant's conduct to help determine the scope of a consensual search."
United States v. Maldonado
,
Furthermore, the purpose of the search was clear. As the Supreme Court has explained, the "scope of a search is generally defined by its expressed object."
Jimeno

B. Sentencing
Mr. Thurman also challenges the district court's findings underlying its application of the Sentencing Guidelines. The court set Mr. Thurman's base offense level at 28 based on a finding that he was responsible for between 700 grams and one kilogram of heroin.
See
U.S.S.G. § 2D1.1(c)(6). It also applied a two-level enhancement after finding that he possessed a dangerous weapon in connection with the drug offense.
See
U.S.S.G. § 2D1.1(b)(1). Mr. Thurman contends that these determinations violate his Fifth Amendment right to due process and his Sixth Amendment right to trial by jury, respectively. We review the court's application of the Guidelines de novo and its factual findings for clear error.
United States v. Cherry
,
1.
Mr. Thurman first attacks the court's drug-quantity finding. Although the jury convicted him of distributing only 100 grams or more of heroin, the court selected his base offense level based on 700 grams to one kilogram of heroin. The court arrived at that figure by considering the amount of heroin seized from Williams in August 2013, the amount of heroin Williams purchased in the controlled buy, the amount of money and drug paraphernalia found in Mr. Thurman's basement, and Mr. Thurman's own admission that he sold approximately 800 grams to Williams over a three-month period. The court declined to consider Williams's statement to the grand jury that he had obtained an additional 1.15 kilograms from Mr. Thurman between the spring of 2012 and August 2013.
The standards that apply to drug-quantity findings at sentencing are well established:
[A] preponderance of the evidence is all that is required for a factual finding of drug quantity under the Sentencing Guidelines, due process concerns notwithstanding. Determining drug quantities under the Sentencing Guidelines is often difficult, and district courts may make reasonable though imprecise estimates based on information that has indicia of reliability.... At the same time, ... a district court choosingamong plausible estimates of drug quantity should normally err on the side of caution.
United States v. Bozovich
,
After a careful review of the record, we conclude that there was more than sufficient evidence to support the court's drug-quantity finding. When Williams first was arrested in August 2013, the police seized 498 grams of heroin from his spare tire, which he attributed to a recent purchase from Mr. Thurman. This attribution was corroborated by the officers' surveillance records, which placed Williams near Mr. Thurman's house the day before. The $27,000 found in a safe in Mr. Thurman's basement, along with packaging tape, plastic baggies, and electronic scales, also demonstrates the scale of his drug operation.
Moreover, Mr. Thurman admitted to authorities that he had distributed approximately 800 grams of heroin to Williams over a three-month period. "Self-incriminating statements ... clearly against [a defendant's] penal interest, have long been considered reliable enough for use at trial, so we cannot say that they are too unreliable for use at sentencing."
United States v. Tankson
,
We cannot accept Mr. Thurman's contention that the court's reliance on Williams's testimony violated his "due process right to be sentenced on the basis of accurate information."
Bozovich
,
2.
Mr. Thurman's challenge to the firearms enhancement fares no better. He contends that the district court erred in applying an enhancement for possession of a dangerous weapon given the jury's previous acquittal on the firearms charge. Despite the jury's acquittal, the court found that Mr. Thurman was in constructive possession of two firearms in connection with the drug offense. Both handguns were found during the execution of the search warrant. A .40 caliber Glock was enclosed in a box in a trash bag filled with books in the basement; a .380 caliber Bryco was stored in a box in a closet upstairs. Both guns either were loaded or had loaded magazines nearby. We review the district court's finding of a relationship between the weapons and the drug offense for clear error.
United States v. Perez
,
Mr. Thurman maintains that the court's consideration of acquitted conduct violates his Sixth Amendment right to be tried by a jury. He acknowledges the Supreme Court's opinion in
United States v. Watts
, which allows a sentencing court to consider conduct of which a defendant was acquitted at trial if the Government can prove that conduct by a preponderance of the evidence.
Mr. Thurman's position clearly is foreclosed by the Supreme Court's opinions and our circuit precedent. In
Watts
, the Supreme Court upheld a district court's application of the firearms enhancement at issue here despite the jury's acquittal on the same firearms charge that Mr. Thurman faced. The Court explained that its decision did "not punish a defendant for crimes of which he was not convicted, but rather increase[d] his sentence because of the manner in which he committed the crime of conviction."
Watts
,
Mr. Thurman next contends that even within the framework of
Watts
, the court erred in finding that he possessed a dangerous weapon under
Application note 11 for U.S.S.G. § 2D1.1 lays out the relevant framework. It provides that the enhancement "should be applied if the weapon was present, unless it is clearly improbable that the weapon was connected with the offense."
Id
. We have construed this provision as imposing a twofold burden. First, the Government must prove by a preponderance of the evidence that the defendant possessed a weapon either actually or constructively, meaning he "had the power and the intention to exercise dominion or control of the firearm."
United States v. Morris
,
Based on our case law, it is clear that the Government satisfied its burden. We have stated repeatedly that "guns found in close proximity to drug activity are presumptively connected to that activity."
United States v. Bothun
,
Our decisions in
Rea
,
Are
, and
Smith
demonstrate the futility of Mr. Thurman's argument. In order to establish constructive possession, the Government did not need to show that the guns were within his immediate reach. Both of Mr. Thurman's guns were kept in the house from which he distributed large quantities of heroin. One gun was kept in a closet, similar to the scenario in
Rea
, and the other gun was kept in close proximity to the safe where Mr. Thurman stored large amounts of ostensible drug money, much like the situation in
Are
. The hidden location of the latter gun in a packed trash bag does not undermine the district court's finding of constructive possession.
See
Perez
,
Conclusion
The district court properly denied Mr. Thurman's motions to suppress. The court's decision rests on its finding that the agents were credible. It was entitled to make that finding. The record before us supports the conclusions that Mr. Thurman voluntarily waived his Miranda rights and voluntarily consented to the search of his cell phone, including the forensic examination.
Mr. Thurman's challenges to his sentence also must fail. All of his arguments rely on a misconception of the district court's sentencing prerogative. The court was entitled to consider evidence proven by a preponderance of the evidence, and the record adequately supports its findings. Accordingly, the judgment is affirmed.

The agents remembered a similar response by Mr. Thurman when they asked if they could search his second residential property.

See, e.g.
,
United States v. Hicks
(
Hicks I
),
The Government contends that Mr. Thurman has waived this challenge by failing to raise it before the district court and failing to provide good cause for that omission. See Fed. R. Crim. P. 12(b)(3)(C) (providing that a motion to suppress must be raised before trial). Mr. Thurman insists that his claim of non-consent encompasses his challenge to the scope of consent. Because we conclude that Mr. Thurman's consent extended to the forensic search, we need not decide whether Mr. Thurman waived or forfeited this argument. His challenge fails under any standard of review.
We note parenthetically that during trial the officers testified that they asked Mr. Thurman about his recent transaction with Williams, and Mr. Thurman admitted that he had erased his text messages arranging that sale. The agents did not attempt to mislead Mr. Thurman or otherwise obfuscate the purpose of their investigation.
