Before WOLLMAN, LOKEN, and MURPHY, Circuit Judges.
                         ____________

PER CURIAM.

      A jury found Curtis Lee Dale guilty of conspiracy to manufacture, distribute,
and possess with intent to distribute between 28 and 280 grams of cocaine base, 500
grams or more of a mixture and substance containing cocaine, and 100 grams or more
of a mixture or substance containing heroin in violation of 21 U.S.C. §§ 841(a)(1),
841(b)(1)(B), and 851; possessing with intent to distribute those drugs in violation
of 21 U.S.C. §§ 841(a)(1), 841(b)(1)(B), and 851; and being a felon in possession of
a firearm and ammunition in violation of 18 U.S.C. §§ 922(g)(1) and 924(a)(2). The
district court1 sentenced Dale to 300 months’ imprisonment. Dale challenges the
denial of an evidentiary hearing on his motion to suppress evidence, as well as the
district court’s drug-quantity calculation. We affirm.

       Special Agent Jay Bump of the Drug Enforcement Administration began
conducting surveillance on Dale in May 2016, after receiving information that Dale
was selling crack cocaine. Agent Bump followed Dale to a self-storage facility in
Davenport, Iowa, on at least four occasions. On May 27, 2016, Agent Bump served
an administrative subpoena on the manager of the facility, who then provided a list
of tenants. Two of Dale’s associates rented storage units, including Unit G-15.

       A warrant-authorized tracking device was installed on the sport utility vehicle
(SUV) that Dale had been driving.2 Data from the tracking device revealed that the
SUV visited the storage facility twice on May 31, 2016, and traveled to the Chicago,
Illinois, area on June 1, 2016. The SUV remained near Chicago for twenty minutes
before beginning its return trip to Davenport. While the vehicle was in Illinois, a
drug dog alerted to the presence of drugs as an officer walked it around Unit G-15.

      The SUV proceeded directly to the self-storage facility, stopping at Unit G-15.
Agent Bump observed Dale exit the SUV, open its rear hatch, and enter the unit.
Dale left the area eight minutes later.

the Southern District of Iowa.

       In a pro se appellate brief, Dale challenges the tracking-device warrant. We
discern no good cause for Dale’s failure to raise this argument before trial, and thus
decline to reach the merits. See Fed. R. Crim P. 12(c)(3); United States v. Anderson,

, 740-41 (8th Cir. 2015); see also United States v. Green, 

,
966 (8th Cir. 2012) (“[P]ro se status alone does not constitute good cause.”).

                                         -2-
       In response to Agent Bump’s application, a federal magistrate judge issued
warrants that authorized a search of Dale’s residence, the SUV, and the two storage
units. A deputy clerk of court testified that she renumbered the warrants by hand
because the prosecutor had erroneously used the same number on each warrant.

       Law enforcement officers searched Unit G-15 on the afternoon of June 2, 2016.
The search revealed a wrapped kilogram of cocaine, additional cocaine in plastic
bags, approximately five ounces of crack cocaine separated into five plastic baggies,
more than 100 grams of heroin, packaging materials, and items used for conversion
of powder cocaine into crack cocaine. Officers also found a duffel bag containing a
loaded Ruger 9mm pistol, empty plastic kilogram-sized wrappings, discarded
packaging material, plastic gloves, and plastic bags. An expert testified that the
officers found “at least two and . . . likely three kilogram wrappers.”

       Officers took Dale into custody at a business establishment in Davenport and
explained that drugs and a gun had been found in Unit G-15. A pat-down search
revealed seven small packages of heroin in Dale’s pocket. After explaining that the
officers were heading to Dale’s residence to search it, Agent Bump read Dale the
Miranda warnings.

       Dale elected to speak with the officers, telling Agent Bump that he had
purchased one kilogram of cocaine for $39,500 from an individual in Chicago on
June 1, 2016, and that he typically sold cocaine for $1,500 per ounce. Dale admitted
that he had $20,000 “on the street” and that he had hidden $3,000 under a rug in his
bedroom, which officers later found.

      Sergeant Larry Hufford waited with Dale in a police vehicle while officers
searched Dale’s residence. Sergeant Hufford had worked at the Rock Island Police
Department since 1994, and he knew Dale “pretty much [his] whole career.”
Sergeant Hufford reminisced with Dale about “a few incidents that happened in the

                                         -3-
mid nineties,” with Dale bragging that he used to purchase large amounts of crack
cocaine in Chicago, transport it to the Quad Cities, and sell it for $800 per ounce.
Dale complained about current drug prices, stating that he had to cook the cocaine
into crack cocaine to make a profit, a process that yielded an extra two and a half
ounces of product. Dale told Hufford that he sold the crack cocaine for $1,500 per
ounce.

       After Dale decided to represent himself, an assistant federal defender was
appointed as standby counsel. Dale filed two pro se motions to suppress, which the
district court denied without holding an evidentiary hearing. The jury found Dale
guilty of the above-described charges. Although the government had argued that the
conspiracy involved 280 grams or more of crack cocaine, the jury found that Dale was
responsible for more than 28 grams but less than 280 grams.

       The presentence report attributed one kilogram of crack cocaine and two
kilograms of cocaine to Dale on the basis of the empty wrappers found in the duffel
bag in Unit G-15. Over Dale’s objection, the district court adopted the report’s drug-
quantity calculation.

      Dale first argues that the district court abused its discretion in denying an
evidentiary hearing on his motions to suppress evidence. United States v. Stevenson,

, 830 (8th Cir. 2013) (standard of review). “A district court must hold
an evidentiary hearing only when the moving papers are sufficiently definite, specific,
and detailed to establish a contested issue of fact.” Id.; see United States v. Losing,

, 1177 (8th Cir. 1976).

       In his first motion, Dale claimed that the administrative subpoena was invalid
and that the warrant to search Unit G-15 was illegal because the warrant was not
addressed to Dale or the owner of the unit and because the addressee was not notified
that a search warrant had issued. The motion failed, however, to allege any factual

                                         -4-
basis for finding that Dale had a reasonable expectation of privacy in the list of
individuals who rented storage units or in the units themselves. See United States v.
McIntyre, 

, 1111 (8th Cir. 2011) (finding no reasonable expectation of
privacy in electricity usage records); United States v. Ruiz-Zarate, 

, 689
(8th Cir. 2012) (finding no reasonable expectation of privacy in an associate’s vehicle
that defendant “neither owned nor was near at the time of the traffic stop”).

       Dale’s second motion challenged his warrantless arrest and sought to exclude
his post-arrest statements. Dale claimed that the arrest was illegal because the
officers did not have a warrant, but he did not assert any factual basis for finding that
the officers lacked probable cause for the arrest. See United States v. Winarske, 

, 1066 (8th Cir. 2013) (“A warrantless arrest by law enforcement is
reasonable where there is probable cause to believe that someone has committed or
is committing a crime.”). Dale also claimed that although he had told the officers that
he did not want to cooperate, they nonetheless “badgered” and “coerced” him to
divulge his cell phone pass code and used “fundamentally unfair manners” to pressure
him to provide information. The motion failed, however, to set forth factual
allegations that might support his claim that the officers violated his Fifth
Amendment right against self-incrimination. See United States v. Adams, 

, 323 (8th Cir. 2016) (“To adequately invoke [the right to remain silent] and
effectively cut off questioning, a suspect must indicate a clear, consistent expression
of a desire to remain silent.” (quoting United States v. Johnson, 

, 955 (8th
Cir. 1995))); United States v. Williams, 

, 815 (8th Cir. 2014)
(“Statements . . . are involuntary where an individual’s will is overborne by coercive
police activity and he loses the capacity for self-determination.”).

       Finally, Dale claimed that “three of the search warr[a]nts [were] altered.” But
he did not allege any details that would enable the court to conclude that the
alterations rendered the search warrants invalid. Dale also reiterated his challenge to
the search of Unit G-15, claiming that Agent Bump did not see Dale enter the unit and

                                          -5-
that Agent Bump “could not see if anything illegal was going on” within the unit.
But again, Dale failed to allege facts that might have allowed the court to find that he
had a reasonable expectation of privacy in the unit. We thus conclude that the district
court did not err in not holding an evidentiary hearing on Dale’s motions.

        We also reject Dale’s argument that the district court did not adequately
reconsider the motions to suppress at the close of the evidence. The court gave Dale
the opportunity to present argument and additional evidence. Dale decided to rely
upon the evidence that had been presented at trial, and the district court did not err
in failing to sua sponte order a separate evidentiary hearing.

       Dale contends that the district court erred in finding him responsible for a
quantity of crack cocaine greater than the quantity range found by the jury. While the
jury found beyond a reasonable doubt that Dale was responsible for between 28 and
280 grams of crack cocaine, the government presented sufficient evidence at trial to
permit the district court to find by a preponderance of the evidence that Dale was
responsible for more than 280 grams of crack cocaine. See United States v. Radtke,

, 844 (8th Cir. 2005) (concluding that after jury’s acquittal, the district
court was “free, indeed obliged, to consider whether [the defendant’s] involvement
had been proved by a preponderance of the evidence”). The government established
that there were three empty kilogram wrappers found in Unit G-15, that Dale had
admitted that he had converted a kilogram of cocaine into crack cocaine, and that Unit
G-15 contained crack cocaine and tools used in the conversion of powder cocaine into
crack cocaine. Moreover, two customers testified that they had purchased crack
cocaine from Dale. In light of this evidence, we conclude that the district court’s
drug-quantity finding was not clearly erroneous. See United States v. Bradley, 

, 1126 (8th Cir. 2011) (standard of review).

      The judgment is affirmed.
