KELLY, Circuit Judge.

      Tyson Trotter was convicted by a jury of a conspiracy to distribute, and to
possess with intent to distribute, methamphetamine in violation of 21 U.S.C. § 846.
The district court1 sentenced Trotter to the statutory mandatory minimum sentence of

        The Honorable Ralph R. Erickson, Chief Judge, United States District Court
for the District of North Dakota.
twenty years’ imprisonment, pursuant to 21 U.S.C. § 841(b)(1)(A). On appeal, Trotter
asserts the district court erred in allowing testimony at trial regarding text messages
in violation of the best evidence rule. He also appeals his conviction on the grounds
that the evidence was insufficient to prove he entered into a conspiracy and that the
court’s jury instructions were erroneous. Finally, he claims error in the calculation of
the amount of drugs attributable to him for purposes of sentencing. Having
jurisdiction under 28 U.S.C. § 1291, and finding no error, we affirm.

                                   I. Background

       In June 2014, Katie Feist took over her husband’s methamphetamine
distribution business after he was arrested and sent to prison. Later that summer, she
started getting methamphetamine from John Dheilly. Dheilly told Feist his supplier
was named “Tyson”—Trotter’s first name—and that they met in the parking lot of a
restaurant named Mabel Murphy’s in Fergus Falls, Minnesota, to exchange drugs and
money.

      In November 2014, Feist approached the Grand Forks Narcotics Task Force
(GFNTF) and offered to help them with their investigation of drug trafficking in the
Grand Forks area in an effort to earn a reduction in her husband’s sentence. On
November 19, 2014, Feist conducted a controlled buy of methamphetamine from
Dheilly, providing him $3,000 in marked money.

       On November 22, 2014, Feist accompanied Dheilly to Mabel Murphy’s
restaurant to obtain methamphetamine. Members of the GFNTF and the West Central
Drug and Violent Crimes Task Force conducted surveillance and observed Dheilly get
something out of the trunk of a white BMW. Law enforcement stopped both Dheilly’s
vehicle and the BMW after they left the parking lot. Trotter was driving the BMW.
During a search of the BMW, officers found $13,000 under the car seat and $3,000
in the center console. The serial numbers on $2,900 of the money found in the

                                          -2-
console matched the serial numbers on the money Feist had given Dheilly in the
controlled buy on November 19, 2014. During a search of Dheilly’s car, officers
found almost half a kilo of methamphetamine, various items associated with the use
of methamphetamine, and three cell phones.

      On November 26, 2014, Feist informed GFNTF officers that additional drugs
would be found in her apartment. The officers conducted a consent search of the
apartment and found approximately 40 grams of methamphetamine, drug
paraphernalia, and $611 in cash. Feist told officers the money was drug proceeds.

      On December 18, 2014, a grand jury indicted Trotter and Dheilly on one count
of a drug conspiracy in violation of 21 U.S.C. § 846. Trotter proceeded to trial.
Various members of the GFNTF testified, as did Feist.

       Joel Lloyd, the agent assigned to work with Feist, testified that after a search
warrant was obtained for the cell phones found in Dheilly’s vehicle, he extracted all
text messages from Dheilly’s contact list, saving the information to a thumb drive.
Agent Karsten Anderson analyzed the drive and prepared a 345-page exhibit
containing all text messages between Dheilly and Trotter from July 26, 2014, through
November 22, 2014. At trial, Anderson testified about the text messages and his
report was admitted as Exhibit 35.

       After trial, Trotter was convicted of conspiracy to distribute, and to possess with
intent to distribute, 500 grams or more of methamphetamine, and he was sentenced
to the statutory mandatory minimum sentence of twenty years in prison. We address
each of Trotter’s alleged errors in turn.




                                           -3-
                                    II. Discussion

        We first address Trotter’s argument that allowing Agent Anderson to testify as
to the content of the text messages between Trotter and Dheilly from July 26, 2014,
through November 22, 2014, violated Federal Rule of Evidence 1002, the best
evidence rule.2 Trotter asserts Anderson’s testimony violated the rule because only
“some of the text messages from November 22” were introduced into evidence.
Trotter did not object to the officer’s testimony before the district court, so our review
is for plain error.3 United States v. White Bull, 

, 1091 (8th Cir. 2011)
(holding that if there is not a timely objection to the admission of evidence at trial,
review is for plain error). To obtain relief under plain error review, Trotter “must
show (1) the district court committed an error, (2) the error is clear or obvious, and (3)
the error affected his substantial rights.” 

these first three requirements are
met, however, we “will only reverse if the error ‘seriously affect[s] the fairness,
integrity or public reputation of judicial proceedings.’” United States v.
Jean-Guerrier, 

, 1091 (8th Cir. 2012) (quoting Puckett v. United States,

, 135 (2009)).

      Trotter cannot meet this burden. Contrary to Trotter’s assertion otherwise,
Anderson’s report contained all the text messages between Trotter and Dheilly from
July 26, 2014, through November 22, 2014, as extracted from Dheilly’s cell phone.
Anderson’s report was then admitted at trial as Exhibit 35. Because the messages
themselves were admitted into evidence, and Anderson’s testimony was based on
them, allowing Anderson to testify about the text messages did not violate the best
evidence rule. See United States v. Buchanan, 

, 523–24 (8th Cir. 2010)

       Rule 1002 provides that “[a]n original writing, recording, or photograph is
required in order to prove its content unless these rules or a federal statute provides
otherwise.”

       Trotter’s appellate attorney did not represent him at trial.

(“The purpose of the best evidence rule . . . is to prevent inaccuracy and fraud when
attempting to prove the contents of a writing.” (quoting United States v. Yamin, 

, 134 (5th Cir. 1989))).

      Trotter next argues the evidence presented at trial was insufficient to prove
Trotter and Dheilly entered into a conspiracy. Trotter contends the evidence showed
no more than a buyer-seller relationship. Our review of the sufficiency of the
evidence is de novo. United States v. Ruiz-Zarate, 

, 689 (8th Cir. 2012).
We will not reverse unless no reasonable jury could have found the defendant guilty.

that Trotter conspired to distribute and possess with the intent to
distribute methamphetamine under 21 U.S.C. § 846, the government must show (1)
he entered into an agreement to distribute and possess with intent to distribute
methamphetamine, (2) he knew the purpose the agreement, and (3) he intentionally
joined the conspiracy. See United States v. Sanchez, 

, 834 (8th Cir.
2015). An agreement to join a conspiracy does not have to be explicit; it may be
inferred from the facts and circumstances of the case. 

agreement of
one person to buy what another agrees to sell, standing alone, does not support a
conspiracy conviction.” United States v. Huggans, 

, 1222 (8th Cir.
2011) (quoting United States v. Prieskorn, 

, 634 (8th Cir. 1981)). While
proof of a conspiracy requires evidence of more than simply a buyer-seller
relationship, we have limited buyer-seller relationship cases to those involving “only
evidence of a single transient sales agreement and small amounts of drugs consistent
with personal use.” United States v. Boykin, 

, 948–49 (8th Cir. 2015)
(quoting United States v. Peeler, 

, 776 (8th Cir. 2015)). As we have
noted, “[e]vidence of multiple sales of resale quantities of drugs is sufficient in and
of itself to make a submissible case of a conspiracy to distribute.” 

(quoting United States v. Conway, 

, 588 (8th Cir. 2014)).



                                         -5-
      Trotter does not dispute that there was evidence to show he sold
methamphetamine to Dheilly on November 22, 2014, but argues the only other
evidence supporting a conspiracy was the testimony of Feist. Trotter asserts Feist’s
testimony was unreliable because she was using methamphetamine and admitted her
drug use negatively affected her memory.4

      Assessing the credibility of witnesses is a task for the jury. United States v.
Malloy, 

, 861 (8th Cir. 2010). “A jury’s credibility determinations are
well-nigh unreviewable because the jury is in the best position to assess the credibility
of witnesses and resolve inconsistent testimony.” United States v. Hodge, 

, 618 (8th Cir. 2010). It is “[o]nly when credibility determinations are internally
inconsistent, based upon incoherent or implausible testimony, or directly at odds with
objective evidence” that a more searching review is warranted. 

not the
case here.

      Feist testified about traveling with Dheilly on more than one occasion to the
Mabel Murphy’s parking lot to get methamphetamine from a person named “Tyson.”
She testified that the amounts of methamphetamine they obtained were not small,
personal use amounts, but larger quantities for distribution. Feist and Dheilly then
repackaged and sold the methamphetamine. Though Feist conceded that using
methamphetamine affected her memory about some things, such as whether she used
methamphetamine after returning from Fergus Falls on November 22, the text
messages between Dheilly and Trotter corroborated much of her testimony. As even
Trotter concedes, the text messages were compelling evidence of a conspiracy. The
text messages showed Dheilly and Trotter were in contact with each other


      4
        Trotter also argues the evidence was insufficient to support the guilty verdict
because Anderson’s testimony was legally deficient and unfairly prejudicial since it
violated the best evidence rule. As we have noted, however, Anderson’s testimony
was properly admitted. Trotter offers no other reason to question its admissibility or
reliability, so we do not consider this argument in our analysis.
                                          -6-
approximately every month from July through November 2014 and the messages
included discussions of when and where they would meet. The text messages showed
Trotter was involved in an ongoing conspiracy with Dheilly rather than a one-time
buyer-seller relationship. We conclude there was sufficient evidence in the record for
a jury to find Trotter had entered a conspiracy with Dheilly.

       Trotter next argues that the court erred in not instructing the jury first that a
buyer-seller relationship alone is insufficient to create a conspiracy and second that
it could only convict him for the conspiracy he was part of, not any other conspiracy.
Trotter did not request either instruction and so our review is for plain error. United
States v. Looking Cloud, 

, 788 (8th Cir. 2005) (“A party cannot preserve
a claim of instructional error for appellate review unless he makes a sufficiently
precise objection and also proposes an alternate instruction.”).

       A defendant is entitled to an instruction explaining his or her theory of the case
“if the request is timely made and if the proffered instruction is supported by the
evidence and correctly states the law.” United States v. Slagg, 

, 848 (8th
Cir. 2011) (citing United States v. Adams, 

, 898 (8th Cir. 2005)). Here,
Trotter did not timely request a buyer-seller or multiple conspiracy instruction, and
the evidence does not support either instruction. As to the buyer-seller instruction,
Feist’s testimony and the text messages between Trotter and Dheilly demonstrated that
Trotter and Dheilly were meeting at least once a month between July and November
2014 at the Mabel Murphy’s parking lot for the purpose of exchanging
distribution-quantity amounts of methamphetamine and money. See 

–49. “Whether trial evidence established a single conspiracy is determined by
the totality of the circumstances, including consideration of the nature and location of
activities and events, identities of the co-conspirators, and the time frame in which the
acts occurred.” United States v. Sanchez, 

, 835 (8th Cir. 2015) (quoting
United States v. McCauley, 

, 1123 (8th Cir. 2013)). Trotter’s argument
that there were multiple conspiracies in this case amounts to little more than an

                                          -7-
extension of his argument that he was not a knowing member of the charged
conspiracy, and he identifies none of the factors relevant to the determination. The
district court committed no error in not submitting either a buyer-seller or a multiple
conspiracy instruction to the jury. See Looking 

.

     Finally, Trotter argues that “the jury clearly erred in attributing 514.07 grams
of methamphetamine to [him]”—an amount triggering the statutory mandatory
minimum sentence of twenty years’ imprisonment under 21 U.S.C. § 841(b)(1)(A).5
He contends there was no evidence to connect him to the 27.75 grams of
methamphetamine Feist purchased from Dheilly on November 19, 2014, or the 39.94
grams found during the November 26, 2014, search of Feist’s apartment. If these
amounts are not included, Trotter asserts, he would not be subject to the twenty-year
mandatory minimum.

        “We review the sufficiency of the evidence de novo, viewing the evidence in
the light most favorable to the jury’s verdict, resolving conflicts in the government’s
favor, and accepting all reasonable inferences that support the verdict.” United States
v. Jefferson, 

, 833 (8th Cir. 2013). As an initial matter, we note that the
jury did not attribute a specific amount of methamphetamine to the conspiracy—it
found that the quantity of methamphetamine that was distributed or intended to be
distributed as part of the conspiracy was 500 grams or more. Thus, we do not know
if the jury included the disputed quantities when reaching the “500 grams or more”
finding. But even if the jury did not include these amounts, there was evidence of
additional transactions between Trotter and Dheilly. For example, Feist testified that


      5
       Section 841(b)(1)(A)(viii) requires a district court to sentence a defendant
convicted of distributing, or possessing with the intent to distribute, “500 grams or
more of a mixture or substance containing a detectable amount of methamphetamine,”
who has a finalized prior conviction for a felony drug offense, “to a term of
imprisonment which may not be less than 20 years and not more than life
imprisonment . . . . ” Trotter does not dispute he has a qualifying conviction.
                                         -8-
she accompanied Dheilly to the Mabel Murphy’s restaurant at the end of August,
where Dheilly obtained a pound of methamphetamine. The text messages between
Trotter and Dheilly around that time corroborate this testimony, showing the two men
planned to meet at this location for the purpose Feist described. Other text messages
indicated Trotter and Dheilly also met at the end of July. We conclude there was
sufficient evidence to support the jury’s finding on the quantity of methamphetamine
attributable to the conspiracy on which Trotter was convicted.

       To the extent that Trotter asserts the district court erred in relying on the jury’s
finding, we disagree. Because Trotter did not make this argument to the district court,
our review is for plain error. United States v. Caballero, 

, 822 (8th Cir.
2005). The jury found beyond a reasonable doubt that Trotter was responsible for 500
grams or more of a mixture containing methamphetamine. Accordingly, that quantity
became the “floor” for sentencing purposes. United States v. Umanzor, 

, 1062 (8th Cir. 2010); see also United States v. Campos, 

,
1015–16 (8th Cir.2004) (“Once the jury found beyond a reasonable doubt that the
amount of methamphetamine [the defendant] intended to distribute was [500] or more
grams, it was a legal impossibility for the district court to find by a preponderance of
the evidence that the amount [the defendant] intended to distribute was less than [500]
grams.”). The district court did not make any drug quantity findings that increased
Trotter’s sentence above the statutory mandatory minimum sentence required by the
jury’s finding in the special interrogatory, and thus committed no error, plain or
otherwise.

                                    III. Conclusion.

      For the reasons set forth above, we affirm the judgment of the district court.
