Before KING, JOLLY, and PRADO, Circuit Judges.
PER CURIAM:*
       The appellants, Enrique Mendez, Carlos Flores, Sr., and Carlos Flores,
Jr., were convicted of conspiracy to distribute more than five kilograms of
cocaine. In addition, Mendez was convicted of conspiracy to launder money,
and three counts of aiding and abetting the transfer of currency from the
United States to Mexico to promote drug trafficking. Flores Sr. was also


       * Pursuant to 5TH CIR. R. 47.5, the court has determined that this opinion should not
be published and is not precedent except under the limited circumstances set forth in 5TH
CIR. R. 47.5.4.

                                 No. 14-41284
convicted of aiding and abetting possession with intent to distribute five
kilograms or more of cocaine.
      On appeal, the defendants assert a host of arguments regarding both
their convictions and their sentences.      We find no reversible error, and
accordingly affirm the district court’s judgment.
                                       I.
      This case involves a drug trafficking conspiracy.           Cocaine was
transported from the border city of Laredo, Texas, to Atlanta, Georgia, for
distribution, and the resulting proceeds were transported from Atlanta back to
Laredo. A principal was Elbert Figueroa. Figueroa has been involved in the
drug trafficking business in Mexico for many years. In 2006, Figueroa moved
to Laredo from Mexico, where he was put in charge of coordinating the delivery
of cocaine from Laredo to Atlanta, and the return of cash to Mexico. Flores Sr.
and Flores Jr. were involved on the drug trafficking side of the operation. They
carried large amounts of cocaine from the nearby town of Zapata, Texas, to
Laredo for eventual shipment to Atlanta and, as noted, Figueroa moved the
cocaine on to Atlanta. Mendez, who owned a trucking company, arranged
transport of the proceeds from Atlanta back to Laredo. Figueroa was arrested
in 2010 for his involvement in the conspiracy at issue and, as a cooperating
witness in this case, helped to shatter the operation.
      Eduardo Delgadillo was another important figure in this conspiracy.
Delgadillo worked for Mendez, helping coordinate the transport of proceeds
from Atlanta to Laredo. According to Delgadillo, he served as the point of
contact between Figueroa and Mendez. Delgadillo was also arrested in 2010,
and was also a cooperating witness in the prosecution of the appellants.
      Finally, there are two important forms of documentary evidence in this
case. First, upon arresting Figueroa, law enforcement officers seized a ledger
documenting cocaine and cash shipments. The ledger includes dates, names
                                       2
    Case: 14-41284     Document: 00513463901     Page: 3   Date Filed: 04/13/2016



                                  No. 14-41284
(although often trafficking pseudonyms), and the amounts of drugs/cash
involved in each transfer. Second, law enforcement obtained Title III wire taps
for both Figueroa’s and Delgadillo’s cell phones. According to the government,
many of the intercepted calls record the appellants’ discussions of drug activity.
                                       A.
      Police began monitoring Figueroa’s phone calls in early 2009. Mendez
spoke with Figueroa over the phone several times in March 2009, each time
complaining that he did not receive the cut he was promised.             He also
complained about his trafficking pseudonym, “Kike.” Mendez preferred “La
Jabia.” On March 25, 2009, Figueroa and Mendez again spoke on the phone
after approximately $500,000 in drug proceeds was seized.
      In May 2009, Figueroa called Delgadillo to arrange for transport of
approximately $1 million in drug proceeds from Atlanta to Laredo. Delgadillo
testified that he, in turn, spoke to Mendez about moving the cash. Mendez
arranged for the transfer to occur on May 21, 2009, but became nervous when
he noticed an airplane—actually a Drug Enforcement Agency (“DEA”) spotter
plane—circling his trucking business on the day of the transaction.
Nevertheless, Mendez instructed Delgadillo to proceed with the transfer
attempt. The cash was ultimately seized when local law enforcement pulled
over the courier. Later that evening, Figueroa spoke with Mendez on the
phone, and demanded that Mendez obtain some official documentation of the
seizure so that Figueroa could show his bosses in Mexico what happened to the
money.
      In July 2009, after yet another cash seizure by law enforcement,
Figueroa demanded to meet with Mendez in person. Mendez and Figueroa met
at a grocery store in Laredo. Delgadillo was also present. The group travelled
to a nearby restaurant, where they had a conversation regarding the recent
uptick in cash seizures. Law enforcement officials surveilled this meeting.
                                        3

                                 No. 14-41284
                                       B.
      While coordinating with Mendez regarding the shipments of cash from
Atlanta to Laredo, Figueroa also had dealings with Flores Sr. and Flores Jr.
regarding cocaine to be shipped from Zapata to Laredo, and eventually to
Atlanta. In coordinating these shipments, Figueroa had phone conversations
with a man he knew only as “Gordo.” Figueroa documented these shipments
in his ledger.   Several government agents testified that, based on their
familiarity with Flores Sr.’s voice, they believed that “Gordo” was actually
Flores Sr. Testimony also showed that Flores Sr.’s actions were consistent
with plans made between Figueroa and “Gordo” on the recorded phone calls.
      On May 14, 2009, Figueroa and Gordo held several phone conversations
during which they arranged for transfer of 100 kilograms of cocaine from
Zapata to Laredo. Figueroa documented the cocaine shipment in his ledger as
being attributable to Gordo. On September 13, 2009, Figueroa called Gordo
again, and arranged to meet at a nearby restaurant to exchange another large
load (over 100 kilograms) of cocaine. Two unidentified men arrived in a small
white SUV. One of the men accompanied Figueroa to his house, where they
unloaded the cocaine.     The exchange was once again surveilled by law
enforcement, and is documented in Figueroa’s ledger as being attributable to
Gordo. When following the white SUV to Figueroa’s home, agents noticed a
second car following the vehicle, apparently attempting to discern whether the
load car was being tailed by law enforcement. One of the agents testified that
he “got a good look” at the second car’s driver, and that it was Flores Sr.
      Two weeks later, on September 28, 2009, Gordo called Figueroa and
arranged another drug exchange, this one to be held in the parking lot of a
sporting goods store. Figueroa arrived at the store. Soon after, both Flores Sr.
and Flores Jr. arrived in separate cars. Flores Sr. was in a white Cadillac
Escalade; Flores Jr. was in a Nissan 350z. Flores Sr. was with his wife, and
                                        4
    Case: 14-41284        Document: 00513463901        Page: 5    Date Filed: 04/13/2016



                                      No. 14-41284
did not have any direct contact with Figueroa. Instead, Flores Sr. and his wife
went inside the sporting goods store, while Flores Jr. met with Figueroa in the
Nissan.       Flores Jr. explained to Figueroa how to access the hidden
compartments in the car. Figueroa took Flores Jr.’s Nissan to his house, where
he unloaded approximately 10 kilograms of cocaine. Again, this exchange was
surveilled by law enforcement, and the transaction appeared in Figueroa’s
ledger as attributable to Gordo.
      Flores Sr. and Flores Jr. also were involved in transporting cocaine from
Zapata, Texas, to Peachtree City, Georgia via airplane. 1 Rene Perez, an
associate of Flores Jr. and Flores Sr., was in charge of smuggling this cocaine.
He became a cooperating witness. Beginning in April 2009, Perez flew at least
five loads of cocaine into Peachtree City at Flores Jr.’s and Flores Sr.’s request,
with the average load being approximately 200 kilograms.
       On August 29, 2009, law enforcement officials in Peachtree City were
contacted by the Air Marine Operations Center, which notified them that
Perez’s plane, currently en route from Zapata to Peachtree City, was
considered a “suspicious flight.” An officer disguised as a courtesy van driver
picked up Perez and the other passengers at the airport, and noticed that Perez
was carrying four suitcases. Agents later witnessed Perez give the suitcases
to another individual, who in turn gave them to an individual driving a green
Ford Explorer. Officers eventually pulled over the Explorer, and found 173
kilograms of cocaine in the suitcases. At trial, Perez testified that Flores Jr.
had given him the suitcases.            Perez also testified that, after a previous
successful flight, he watched Flores Sr. and Flores Jr. load the resulting cash
proceeds into a hidden compartment in Flores Sr.’s car. Figueroa apparently




      1   Peachtree City is approximately 20–30 minutes south of Atlanta.

had no knowledge of these cocaine trafficking flights; he did not testify about
them and no entries regarding the shipments appear in his drug ledger.
      In December 2011, approximately fourteen months after Figueroa’s
arrest, Laredo police pulled over Flores Sr. and his wife. The couple were
travelling in the Nissan 350z that had been used in the cocaine exchange at
the sporting goods store in September 2009. Flores Sr.’s wife was driving the
car, and she consented to a search. Officers found a hidden compartment
behind the passenger’s seat that contained approximately $150,000. Before
being told of the discovery, Flores Sr. volunteered knowledge of the money and
the hidden compartment, telling the officers that the money was his and that
his wife did not know anything.
                                       C.
      The three appellants in this appeal, Mendez, Flores Jr., and Flores Sr.,
were indicted in June 2012.       All three were charged with conspiracy to
distribute more than five kilograms of cocaine, in violation of 21 U.S.C. § 841.
Additionally, Mendez was charged with conspiracy to launder money, and
three counts of aiding and abetting the transfer of currency from the United
States to Mexico to promote drug trafficking, in violation of 18 U.S.C. § 1956.
Flores Sr. was also charged with aiding and abetting possession with intent to
distribute five kilograms or more of cocaine, in violation of § 841. Finally,
Mendez was charged with obstruction of justice for threatening a witness.
      This case was tried from July 22 to July 30, 2013. The jury returned a
guilty verdict as to all defendants on all drug-related counts.         Mendez,
however, was acquitted of the obstruction charge. Flores Jr. and Flores Sr.
moved for a new trial, alleging both newly discovered evidence and the
government’s failure to disclose exculpatory evidence.       The district court
denied the motion. Mendez was sentenced to 425 months as to the conspiracy
count and 260 months as to the remaining counts, to run concurrently. Flores

Sr. was sentenced to 405 months as to the conspiracy count and the aiding and
abetting count, to run concurrently. Flores Jr. was sentenced to 405 months
as to the conspiracy court.
                                              II.
       As we have said earlier, the appellants assert myriad and occasionally
overlapping arguments regarding both their convictions and their sentences.
We address the appellants’ challenges to their convictions first. We then turn
to the appellants’ arguments relating to their sentences.
                                              A.
       First, all three appellants argue that the district court erred in allowing
the government to project their respective photographs simultaneous with
recordings of intercepted phone calls before the jury. The government
introduced approximately 100 isolated segments of phone conversations
between either Figueroa or Delgadillo and the appellants.                      Most of the
recordings were in Spanish, and had to be translated for the jury. When
playing the recorded tapes, the government used a computer program that
displayed in real time the English translation of the recorded Spanish
conversation.      The computer program also projected photographs of the
purported speakers for each conversation. According to the defendants, the
purported speaker’s photograph was highlighted as the tapes played. 2
       The photographs were part of a demonstrative aid to assist the jury in
following along during the foreign language conversations. They are thus
subject to Fed. R. Evid. 611. See United States v. Ollison, 555 F.3d 152, 162
(5th Cir. 2009). “[A]llowing the use of . . . pedagogical devices intended to


       2 The photographs were apparently taken from the appellants’ drivers licenses. In
other words, they were not mugshots and did not, on their own, suggest involvement in
criminal activity. Also, the government denies that the photographs were highlighted at any
point, and the district court judge noted that, from her point of view, the photographs did not
appear to be highlighted.
                                              7
    Case: 14-41284       Document: 00513463901        Page: 8    Date Filed: 04/13/2016



                                  No. 14-41284
present the government's version of the case is within the bounds of the trial
court's   discretion   to   control   the       presentation    of   evidence. . . . Such
demonstrative aids typically are permissible to assist the jury in evaluating
the evidence, provided the jury is forewarned that [they] are not independent
evidence.” United States v. Taylor, 210 F.3d 311, 315 (5th Cir. 2000) (internal
quotation marks and footnotes omitted). As an issue within the ambit of Fed.
R. Evid. 611, the district court’s decision to allow the photographic projection
system is reviewed for an abuse of discretion. See United States v. Colomb, 419
F.3d 292, 297 (5th Cir. 2005).
      After thorough review, we conclude that the district court did not abuse
its discretion in allowing the projection of appellants’ photographs when
playing the recorded phone conversations. Before allowing the government to
use the projection system at issue, the district court went to great lengths to
explain to the jury that the photographs were being used merely to help the
jury follow which individual, under the government’s theory of the case, was
alleged to be speaking during the wiretap recordings.                The district court
advised the jury that:
      You’ll see photographs of the speakers on [the screen containing
      the English language translation], just to help in you being able to
      keep track of who it is [] supposedly talking while the tape is
      playing through. But in the end it’s going to be up to you to
      determine if in fact those are the speakers on this particular call.
      And I’ll say not only this call but all the calls. Those are your
      determinations.
This instruction was not an outlier. On at least three other occasions during
the trial, the district court cautioned the jury that the identity of the speakers
was a matter for the jury to determine based solely on admitted evidence and
testimony. The district court’s final jury instructions also informed the jury
that “whether the transcript[s] correctly or incorrectly reflect the . . . identity


                                            8
    Case: 14-41284    Document: 00513463901     Page: 9   Date Filed: 04/13/2016



                                 No. 14-41284
of the speakers, is entirely for you to determine based upon your own
evaluation of the testimony you have heard.”
      The district court explicitly and repeatedly advised the jury that the
photographs represented only the government’s contention, and nothing more,
regarding who was speaking on the wiretap recordings; with such clear
instructions to the jury, we cannot say that the use of the projection system
amounts to an abuse of discretion. See United States v. Patino-Prado, 533 F.3d
304, 313 (5th Cir. 2008) (per curiam) (“We will presume that jurors understand
and follow their instructions, abandoning that presumption only when there is
an overwhelming probability that the jury will be unable to follow the
instruction and there is a strong probability that the effect is devastating.”
(internal quotation marks omitted)).
      The defendants attempt to transform this evidentiary issue into a due
process violation by citing a string of Supreme Court cases regarding “overly
suggestive” pretrial identification procedures. See, e.g., Manson v. Brathwaite,
432 U.S. 98 (1977). These cases are, however, irrelevant to the situation here.
The appellants are not alleging that law enforcement used overly suggestive
techniques to coerce a witness’s in-court or out-of-court identification of a
defendant. Instead, the appellants make what is essentially a Fed. R. Evid.
403 argument, asserting that the photographic projections, although not
actually evidence, nonetheless served to prejudice the defendants by
suggesting that it was a settled fact that their voices appeared on the tapes.
As explained, to the extent that the photographs could have prejudiced the
appellants, the district court’s detailed and repeated limiting instructions were
a sufficient safeguard. Accordingly, we hold that the district court did not




                                       9
    Case: 14-41284       Document: 00513463901          Page: 10     Date Filed: 04/13/2016



                                       No. 14-41284
abuse its discretion in allowing the projection of the defendants’ photographs
as part of a demonstrative aid. 3
       In a related argument, Flores Sr. asserts that the district court erred in
allowing several law enforcement witnesses to identify his voice on the
recorded conversations. This argument is without merit. These government
witnesses stated that they had spoken with Flores Sr. in person, were familiar
with his voice, and could identify it on the recordings.                      Any further
consideration of misidentity was a matter of weight for the jury, not a question
of admissibility for the district court. See United States v. Lampton, 158 F.3d
251, 259 (5th Cir. 1998) (stating that Fed. R. Evid. 901(b)(5) provides that
“[i]dentification of a voice, whether heard firsthand or through mechanical or
electronic transmission or recording, [can be testified to] by opinion based upon
hearing the voice at any time under circumstances connecting it with the
alleged speaker” (internal quotation marks omitted)).
                                             B.
       Mendez alone argues that the district court erred in not granting his
motion for a mistrial after a government witness suggested that Mendez was
also involved in another, uncharged drug offense. This court reviews a district
court’s denial of a motion for mistrial based on prejudicial evidence for an
abuse of discretion. United States v. Richardson, 781 F.3d 237, 246 (5th Cir.
2015). Under this standard, “a new trial is required only if there is a significant
possibility that the prejudicial evidence had a substantial impact upon the jury



       3  Although we hold that the district court did not commit reversible error in allowing
the use of the projection system, we do admonish caution regarding the government’s use of
such methods. Were it not for the district court’s detailed instructions regarding the role of
the appellants’ photographs, as well as the significant amount of other evidence connecting
the defendants to the conspiracy—including surveillance photos, drug ledger entries,
cooperating witnesses’ testimony, eye-witness testimony from law enforcement, and actual
seizures of cash and drugs from the defendants’ associates—we could be faced with a more
difficult question.

verdict, viewed in light of the entire record.” Id (internal quotation marks
omitted).
      Mendez’s argument is based on testimony that occurred during the
government’s redirect of DEA Agent Joe Semidey. On cross examination,
Mendez’s defense attorney asked several questions regarding Semidey’s
familiarity with Mendez’s voice. Semidey’s personal knowledge of Mendez’s
voice having been challenged on cross examination, the government sought
further foundational testimony regarding how Semidey was familiar with
Mendez’s voice.     This line of questioning led to the alleged prejudicial
testimony:
      Q:     Okay. Did you identify Enrique Mendez’[s] voice on some of
             those audios?
      A:     Yes.
      Q:     How is it that you are able to identify his voice?
      A:     Because I have spoken to him before.
      Q:     How many times—well, when did you speak to him?
      A:     I spoke to him on September the 1st when we did the
             takedown, and prior to that, I had—back in 2007, I had
             spoken to him once relating [to] a seizure of some marijuana
             that was found in a ranch that belonged to him, that was
             adjacent to his—
      Mendez contends that Semidey’s comments regarding the seizure of
marijuana from his property amount to impermissible testimony of prior bad
acts under Fed. R. Evid. 404(b). The district court’s prompt remedial action,
however, cured any possible prejudice. The district court sustained Mendez’s
objection, refused to admit the testimony for any purpose, and issued the
following curative instruction:
            There was a question that was asked and then an answer
      provided that referenced a seizure of marijuana on a property that
      allegedly belongs to Mr. Mendez. I’m instructing you right now,


                                        11
   Case: 14-41284     Document: 00513463901     Page: 12   Date Filed: 04/13/2016



                                 No. 14-41284
      you’re not to consider that in any way, shape, or form at all. Do not
      consider that.
            Mr. Mendez has not been charged with that act, and I will
      tell you that there was an individual named Mr. Gamez who
      apparently was leasing that property from Mr. Mendez [and] has
      already been convicted for that particular marijuana.
            So out of your minds, you cannot consider that, that has
      nothing to do with this case. Does everybody understand?
      Such a detailed and forceful curative instruction remedied any prejudice
caused by Agent Semidey’s remark. See Richardson, 781 F.3d at 246, 249
(“[P]rejudice may be rendered harmless by a curative instruction.”).
Accordingly, the district court did not err in denying Mendez’s motion for a
mistrial.
                                       C.
      Flores Sr. and Flores Jr. urge that the district court erred in admitting
evidence regarding the cocaine trafficking flights from Laredo, Texas, to
Peachtree City, Georgia. Defendants contend that the trafficking flights were
“extrinsic” to the single cocaine trafficking conspiracy charged in the
indictment, and that introduction of the evidence essentially violated Fed. R.
Evid. 404(b). Flores Sr. further argues that evidence regarding the $150,000
seized during the December 2011 traffic stop is extrinsic to the charged
conspiracy.
      This court reviews evidentiary rulings for an abuse of discretion;
furthermore, the harmless error doctrine applies when deciding whether to
reverse for erroneous admission of extrinsic evidence. See United States v. Liu,
960 F.2d 449, 452 (5th Cir. 1992). In assessing violations of Rule 404(b), this
court asks (1) whether the evidence is relevant to an issue other than the
defendant's character; and, if it is relevant, (2) whether the evidence possesses
probative value that is not substantially outweighed by the danger of unfair


                                       12

prejudice (i.e., a Rule 403 assessment). See United States v. Beechum, 582 F.2d
898, 911 (5th Cir. 1978) (en banc).
      With certainty, we can say that the district court did not abuse its
discretion in admitting the evidence regarding the cocaine trafficking flights.
As this court has stated numerous times, “[t]he mere entry of a not guilty plea
in a conspiracy case raises the issue of intent sufficiently to justify the
admissibility of extrinsic offense evidence.” United States v. Booker, 334 F.3d
406, 411 (5th Cir. 2003) (internal quotation marks omitted); see also United
States v. Chavez, 119 F.3d 342, 346 (5th Cir. 1997) (“The admission of extrinsic
evidence is permissible under Rule 404(b) when a defendant places his intent
at issue in a drug conspiracy case by pleading not guilty.”).
      Furthermore, the evidence was not unfairly prejudicial. The evidence of
the Atlanta trafficking flights is particularly probative, as it undercuts any
assertion that the defendants lacked the intent or the means to traffic large
amounts of cocaine from southern Texas to the Atlanta area. In addition, the
cocaine trafficking flights were on-going during the period of the charged
conspiracy; thus, the probative value of evidence relating to the flights is not
weakened by a lack of temporal proximity to the charged conspiracy. See id.
      Similarly, the district court did not abuse its discretion in admitting
evidence regarding the $150,000 seized during the traffic stop of Flores Sr. and
his wife. Evidence of the seizure showed that Flores Sr. was aware of the
hidden compartment in his car, as Flores Sr. volunteered knowledge of the
money and the hidden compartment before the arresting officers asked about
it. Furthermore, given Flores’s own admission that he knew of the money and
the hidden compartment, as well as the significant evidence linking Flores Sr.
to drug trafficking within the ambit of the charged conspiracy, a jury could
conclude that the $150,000 was proceeds from the conspiracy, and thus
intrinsic to the conspiracy at issue.

                                       No. 14-41284
       Finally, even if we should assume that the district court erred in
admitting the extrinsic evidence, the error was harmless. Under the harmless
error doctrine, an evidentiary error is reversible only if it affects a party’s
substantial rights. United States v. McCann, 613 F.3d 486, 498 (5th Cir. 2010).
The government has offered ample evidence that Flores Sr. and Flores Jr. were
involved in the conspiracy alleged; such evidence is wholly independent of the
two “extrinsic” incidents challenged here. Accordingly, the district court’s
failure to exclude the extrinsic evidence at issue did not affect the appellants’
substantial rights. 4
                                             D.
       Next, Flores Sr. and Flores Jr. argue that the district court erred in
denying their post-verdict motion for a new trial. Although both Flores Sr. and
Flores Jr. joined in the motion, the “new evidence” at issue concerns only Flores
Sr. “Generally, motions for new trial are disfavored and must be reviewed with
great caution.” United States v. Piazza, 647 F.3d 559, 565 (5th Cir. 2011). To
receive a new trial on the basis of newly discovered evidence, a defendant must
show that: “(1) the evidence is newly discovered and was unknown to the
defendant at the time of trial; (2) failure to detect the evidence was not due to
a lack of diligence by the defendant; (3) the evidence is not merely cumulative
or impeaching; (4) the evidence is material; and (5) the evidence introduced at
a new trial would probably produce an acquittal.” United States v. Franklin,


       4  We also reject the appellants’ argument that the district court erred in not
instructing the jury regarding the difference between a single conspiracy and multiple
conspiracies. Flores Jr. and Flores Sr. do not contend that the government failed to offer any
evidence connecting them to the conspiracy charged, and instead argue only that some of the
evidence offered was extrinsic to the conspiracy at issue. Thus, an instruction regarding
multiple conspiracies was not required. See United States v. Carbajal, 290 F.3d 277, 291 n.25
(5th Cir. 2002) (“A multiple conspiracy instruction is required where the indictment charges
several defendants with one (1) overall conspiracy, but the proof at trial indicates that some
of the defendants were only involved in separate conspiracies unrelated to the overall
conspiracy charged in the indictment.” (emphasis added) (internal quotation marks omitted)).

561 F.3d 398, 405 (5th Cir. 2009). This court reviews a denial of a motion for
new trial on the basis of newly discovered evidence for an abuse of discretion.
Id.
        First, Flores Sr. points to statements that an apparent co-conspirator,
Humberto Gonzalez, made when interviewed by Flores Sr.’s investigator after
trial. According to an affidavit completed by the investigator, Gonzalez, who
was in prison at the time of the interview, asserted that he was one of the two
men driving the white SUV that delivered cocaine to Figueroa on September
13, 2009. After listening to the intercepted recording of “Gordo” and Figueroa
arranging the transaction, Gonzalez asserted that the voice of Gordo was not
that of Flores Sr., and instead belonged to a man named “Manitas.” Gonzalez
further asserted that Manitas, not Flores Sr., hired him to deliver the cocaine.
Gonzalez changed his story in a later interview, asserting that the voice on the
tape was not Manitas, and that someone named “Maria” hired him to deliver
the cocaine. Gonzalez also refused to sign a written affidavit, refused to testify
at any new trial or hearing, and asserted that he would no longer speak about
his involvement in drug trafficking operations without the presence and advice
of an attorney. It follows that the district court did not abuse its discretion in
denying the motion for a new trial on the basis of Gonzalez’s oral statements.
        Flores Sr. also offers evidence that he argues shows he was at a friend’s
house all day on September 13, 2009, mourning the death of one of the friend’s
sons, and thus could not have been involved in the drug transaction that
occurred that day.      Flores Sr. claims that he forgot that he was at the
gathering, but was reminded when photographs of the event appeared on
Facebook in October 2014, which is over five years after the supposed event.
In November 2014, during a hearing on civil forfeiture and sentencing, the
district court heard testimony from Flores Sr.’s friend and her other son.

    Case: 14-41284       Document: 00513463901        Page: 16     Date Filed: 04/13/2016



                                      No. 14-41284
       Flores Sr. has not shown how his failure to offer this evidence during
trial was not a product of a lack of diligence. As the district court noted, Flores
Sr.’s “new evidence” does not depend on the Facebook photos; Flores Sr. could
have, at any time, offered the alibi defense that he was at a friend’s house.
Furthermore, given that so many other friends and family members were also
at the gathering, it would have taken little in the way of retracing his steps for
Flores Sr. to be reminded of this event, assuming that Flores Sr. was at the
gathering for the entire day as he now contends. 5 Accordingly, the district
court did not abuse its discretion in denying Flores Sr.’s motion for a new trial.
       Finally, Flores Sr. asserts that the government failed to disclose
exculpatory evidence. This argument fails, however, for the simple reason that
he has not identified any exculpatory or impeaching evidence that was
supposedly withheld.         At oral argument, Flores Sr. contended that the
government withheld Humberto Gonzalez’s involvement in the September 13,
2009 drug transaction. Flores Sr. asserts that the government had evidence
suggesting that Gonzalez delivered the cocaine to Figueroa on September 13th.
The government, however, has never contended that Flores Sr. actually
delivered the cocaine on that date. Instead, government agents testified that
Flores Sr. followed an unidentified individual—apparently Gonzalez—in a
separate car, and served as a lookout for any law enforcement tails. Even if
Gonzalez were driving the “load” car, this does nothing to exculpate Flores Sr.,
as the government never sought to prove that Flores Sr. actually delivered the
cocaine on September 13th.




       5The district court was skeptical of the testimony regarding Flores Sr.’s presence at
the gathering, asserting that the family friend and her son had nearly identical accounts of
Flores Sr.’s presence at the gathering, but could not remember any of the other events from
that day or week.

                                 No. 14-41284
      Flores Sr. and Flores Jr. also seize upon one agent’s testimony that,
while investigating the defendants, law enforcement was also conducting a
“parallel investigation” of various individuals involved in the conspiracy at
issue, including the defendants themselves. The defendants now contend post-
trial that they are entitled to a review of all files pertaining to the parallel
investigation to see whether any information within those files could have been
used to impeach the government witnesses here. As the district court noted,
defendants are essentially requesting post-trial discovery, not contending that
the government actually withheld exculpatory or impeaching information.
Furthermore, Flores Sr. and Flores Jr. have not taken issue with the
government’s assertion that this “parallel investigation” was merely an
investigation by another federal agency into the defendants’ drug trafficking
activities. Accordingly, the district court did not abuse its discretion when
denying the defendants’ motion for a mistrial based on the withholding of
exculpatory evidence.
                                      III.
      We now turn to the appellants’ challenges to their sentences. Mendez
brings several sentencing-related arguments, contending primarily that (1) the
district court erred in imposing a four-level “leadership” enhancement under
U.S.S.G. § 3B1.1(a); and (2) the district court erred in considering the
allegations that Mendez threatened a government witness, since he was
acquitted of that charge. Mendez also makes a vague, unpreserved argument
regarding the procedural and substantive reasonableness of his sentence.
Flores Sr. and Flores Jr. contend only that the district court erred in
attributing over 450 kilograms of cocaine to them for the purposes of setting a
base offense level under the guidelines.




                                      17
   Case: 14-41284    Document: 00513463901      Page: 18   Date Filed: 04/13/2016



                                 No. 14-41284
                                       A.
      We first consider Mendez’s argument that the district court erred in
assessing a four-level “leadership” enhancement. Mendez does not dispute that
his convictions placed him at a base offense level of 38 under the sentencing
guidelines, which recommends a sentence ranging from 235–327 months. The
district court, however, relied upon U.S.S.G. § 3B1.1(a) to impose a four-level
increase, as the court considered Mendez to be an “organizer or leader” of the
drug trafficking operation at issue. See U.S.S.G. § 3B1.1(a).
      The question of a “leadership” role in a criminal organization is a factual
determination that is reviewed for clear error. United States v. Valdez, 453
F.3d 252, 263 (5th Cir. 2006). When making these factual determinations, the
district court may rely on the information in the Presentence Report (“PSR”)
“so long as the information has some minimum indicium of reliability.” United
States v. Shipley, 963 F.2d 56, 59 (5th Cir. 1992) (per curiam) (internal
quotation marks omitted). The defendant must present rebuttal evidence to
demonstrate that the information contained in the PSR is “materially untrue,
inaccurate or unreliable.” United States v. Washington, 480 F.3d 309, 320 (5th
Cir. 2007) (internal quotation marks omitted). “Mere objections do not suffice
as competent rebuttal evidence.” United States v. Parker, 133 F.3d 322, 329
(5th Cir. 1998).
      That Mendez was a “leader or organizer” for the purposes of the four-
level enhancement is demonstrated by evidence that Mendez was the primary
individual in charge of moving drug proceeds from Atlanta to Laredo. He used
his trucking company to transport large amounts of cash, and employed at
least eight drivers in furtherance of this objective. Mendez organized the
transport of—under the most conservative estimate—at least $2.5 million in




                                       18
    Case: 14-41284       Document: 00513463901          Page: 19     Date Filed: 04/13/2016



                                       No. 14-41284
drug proceeds, 6 and he was entitled to a flat 5% fee. Mendez offers no evidence
rebutting these findings; instead, he merely contends that he is more
accurately described as a mere “supervisor” because the most obvious “leader”
of the drug trafficking operation was Figueroa. There can, however, be more
than one individual who qualifies as a “leader or organizer.” See United States
v. Cooper, 274 F.3d 230, 247 (5th Cir. 2001). Accordingly, Mendez’s argument
that the district court erred in assessing a four-level increase lacks merit.
       We also reject Mendez’s argument that the district court erred in
considering acquitted conduct during sentencing. Mendez contends that the
district court imposed a two-level enhancement for “obstruction of justice”
under U.S.S.G. § 3C1.1, and that it was improperly based on the obstruction
charge for which Mendez was acquitted. Mendez’s argument is, however,
contradicted by the district court’s conclusion at sentencing that Mendez’s total
offense level was 42. Mendez does not dispute that his base offense level was
38, and the only enhancement imposed was the four-level enhancement for his
role as a “leader” in the drug trafficking operation. Thus, the record does not
support Mendez’s assertion that he was assessed a two-level increase for the
obstruction charge. 7
       Finally, we reject Mendez’s unpreserved argument regarding the
procedural and substantive reasonableness of his sentence. Because Mendez
failed to object during sentencing, our review is for plain error. United States
v. Dominguez-Alvarado, 695 F.3d 324, 327 (5th Cir. 2012). This court finds




       6  This figure is simply the amount of cash actually seized. Relying on Figueroa’s
ledgers, the district court found that Mendez was responsible for aiding in the transport of
over $40 million in drug proceeds.
       7 Furthermore, even to the extent that the district court did consider the allegations

of witness tampering, a district court is not foreclosed from considering acquitted conduct at
sentencing, so long as the conduct is proven by a preponderance of the evidence. See United
States v. Watt, 519 U.S. 148, 157 (1997) (per curiam).

                                  No. 14-41284
plain error when: (1) there is error; (2) the error is plain; (3) the error affects
substantial rights; and (4) we may exercise our discretion to remedy the error
if it seriously affects the fairness, integrity, or public reputation of judicial
proceedings. See United States v. Cedillo–Narvaez, 761 F.3d 397, 401–02 (5th
Cir.) cert. denied, 135 S. Ct. 764 (2014); United States v. Mares, 402 F.3d 511,
520 (5th Cir. 2005). “[W]hen a sentencing judge imposes a properly calculated
Guidelines sentence, ‘[this court] will give great deference to that sentence.’”
United States v. Alonzo, 435 F.3d 551, 554 (5th Cir. 2006) (quoting Mares, 402
F.3d at 520).
      Mendez has failed to show that the district court committed any error,
much less “plain error.” Mendez does not contend that, absent the four-level
increase for a “leadership” role, the guidelines range chosen by the district
court was improperly calculated.          Furthermore, contrary to Mendez’s
assertions, the district court acknowledged its obligation to consider the
sentencing factors listed in 18 U.S.C. § 3553. There is also nothing in the
record indicating that the district court failed to appreciate its discretion to
downwardly depart from the applicable guidelines range if warranted.
Therefore, Mendez fails to satisfy the first two prongs of plain error review,
and his sentence is due to be affirmed.
                                        B.
      Flores Sr. and Flores Jr. also challenge their sentences, contending that
the district court erred in attributing over 450 kilograms of cocaine to them
when setting a base offense level under the guidelines. See U.S.S.G. § 2D1.1
(stating that an offense involving in excess of 450 kilograms of cocaine has a
base offense level of 38). The district court’s determination of the quantity of
drugs used to establish a defendant’s base offense level is a factual finding
made under the preponderance of the evidence standard and reviewed for clear
error. United States v. Betancourt, 422 F.3d 240, 247 (5th Cir. 2005).
                                        20
    Case: 14-41284       Document: 00513463901         Page: 21     Date Filed: 04/13/2016



                                      No. 14-41284
       The district court did not err in finding that Flores Sr. and Flores Jr.
were responsible for over 450 kilograms of cocaine, thus in setting a base
offense level of 38.      Ample evidence supports the district court’s finding.
Figueroa testified that his cocaine connection in Zapata was a man named
“Gordo,” and Figueroa’s drug ledger indicates that he received well over 450
kilograms from Gordo. Several agents testified that the voice of “Gordo” was
that of Flores Sr., and further testimony places Flores Sr. at the scene of at
least two drug exchanges arranged with “Gordo.”                   Regarding Flores Jr.,
intercepted phone recordings between Figueroa and Flores Jr. indicate that
Flores Sr. and Flores Jr. worked together closely in their drug trafficking
business. 8 In response, Flores Sr. and Flores Jr. assert only that the district
court erred in attributing drugs to them that, although arguably were within
the scope of the conspiracy, were not “reasonably foreseeable” to them
individually. The district court, however, made clear during sentencing that,
in finding that the defendants were responsible for over 450 kilograms of
cocaine, it relied only on drug quantities that were directly attributable to the
defendants’ actions. Thus, the appellants’ argument is meritless.
                                            IV.
       Mendez, Flores Sr., and Flores Jr. have failed to show reversible error on
the part of the district court. Accordingly, the judgment of the district court is
                                                                             AFFIRMED.




       8 In addition, there is evidence that both Flores Jr. and Flores Sr. were personally
involved in shipping approximately 800 kilograms of cocaine from Zapata to Atlanta via a
series of private plane flights. Even assuming that this evidence is “extrinsic” to the
conspiracy at issue, the district court is allowed to use “similar transactions” to gauge the
scope of a defendant’s trafficking operation. See U.S.S.G. § 2D1.1 cmt. n.5.
