TIMOTHY LEDON BOWEN; JUAN CARLOS VEGA; RENE CORTEZ
SALAZAR,

                Appeals from the United States District Court
                      for the Eastern District of Texas

Before HIGGINBOTHAM, OWEN, and ELROD, Circuit Judges.
PER CURIAM:
      Appellants Timothy Bowen, Juan Vega, and Rene Salazar were
convicted of conspiring to possess with intent to distribute methamphetamine
in violation of 21 U.S.C. § 846. Appellants challenge various aspects of their
convictions, and Bowen also challenges his sentence. Because we find no
reversible error in Appellants’ convictions or Bowen’s sentence, we AFFIRM.
                                       I.
      Appellants Bowen, Vega, and Salazar, along with thirty-one other co-
defendants, were indicted by a federal grand jury for conspiracy to possess with
intent to distribute 50 grams or more of methamphetamine or 500 grams or
more of a mixture or substance containing methamphetamine in violation of
     Case: 14-40654        Document: 00513442554          Page: 2     Date Filed: 03/29/2016

21 U.S.C. § 846. See 21 U.S.C. § 841(a), (b)(1)(A)(viii). The relevant evidence
at trial was as follows. 1
       In 2011, local police in the Denison/Sherman area of Texas requested
assistance from the DEA in investigating suspected methamphetamine
distribution activity between Dallas and the Denison/Sherman area. DEA
agent Henry Mata was assigned to the investigation.                       The investigation
initially focused on the Camacho siblings (Manuel, Paul, and Priscilla) in
Dallas who sold methamphetamine to distributors in the Denison/Sherman
area. Paul Camacho led investigators to Andy Nguyen, who was the source of
the Camachos’ supply. Nguyen testified that he worked for a supplier in
Mexico named “Primo” and sold methamphetamine to the Camachos.
       Primo used a carrier named Ramiro Cazares to deliver drugs and drug
proceeds from Mexico to Nguyen’s workers in Dallas. One of Nguyen’s workers,
Manuel Urbina, gave Cazares a black Honda Accord with a hidden
compartment for Cazares to use to store drugs and proceeds. Cazares knew
Appellant Vega from home construction jobs and asked Vega to help him
deliver Primo’s drugs and drug proceeds. Vega agreed and began transporting
the methamphetamine and proceeds, sometimes with Cazares and sometimes
on his own. After Cazares was arrested, Cazares agreed to make a recorded
telephone call to Vega during which Vega recognized “Primo,” mentioned
“cooking” the methamphetamine, and offered to help Cazares move multiple
kilograms of methamphetamine that were hidden in Cazares’s ex-wife’s house.
When Vega was arrested, Vega admitted to Agent Mata that he was a runner
for Cazares and knew there were multiple kilograms of methamphetamine in

       1 We view the evidence in the light most favorable to the jury verdict as it relates to
the sufficiency-of-the-evidence challenges. See United States v. Moreland, 665 F.3d 137, 148
(5th Cir. 2011) (“[J]udges must be highly deferential to the jury’s verdict of conviction: courts
view the evidence in the light most favorable to the prosecution.” (internal quotation marks
and alterations omitted)).

Cazares’s ex-wife’s house. Investigators found the black Honda Accord with
the hidden compartment at Vega’s apartment. A key to the Honda was hidden
inside one of Vega’s home speakers.
         During the time of the alleged conspiracy, Manuel Camacho sold
methamphetamine        to   Appellant   Salazar       who    distributed   it   in   the
Denison/Sherman area.         The Camachos also sold methamphetamine to
Kenneth House, who at first competed with Salazar in the Denison/Sherman
area, but later became Salazar’s partner in distributing methamphetamine
there.     From about 2010 to 2011, House and Salazar also purchased
methamphetamine from another source in Dallas named Fernando Perales.
House’s wife, Christina, would go with House to pick up drugs from Perales.
Perales knew House was distributing the methamphetamine with Salazar in
the Sherman/Denison area.
         An individual named Trey Tibbs purchased methamphetamine from
House and Salazar in 2010 and 2011. Tibbs also worked for House and Salazar
by picking up drug proceeds and delivering methamphetamine for them. When
House went to jail, Tibbs purchased methamphetamine from Salazar. After
Salazar also went to jail, an individual named Charles Quirolo continued the
Salazar/House methamphetamine distribution operation until customers
complained about Quirolo, after which Salazar’s girlfriend, Andrea Reeves,
took over the operation.
         House testified that Salazar sold methamphetamine to both Appellant
Bowen      and   his   brother,   Melvin,       and   that   Salazar   would    “front”
methamphetamine to them when they did not have enough money to pay
Salazar. After Melvin went to jail and still owed Salazar money, Melvin’s wife,
Kisha, started working for Salazar to pay off her husband’s debt. After the
debt was paid, Kisha continued distributing methamphetamine for Salazar.

                                    No. 14-40654

While House and Melvin were in jail, their wives (Christina House and Kisha
Bowen 2) met and became friends. Christina introduced Kisha to Perales, who
had supplied methamphetamine to House and Salazar.
      After House went to jail, Christina House bought methamphetamine
from Perales.      Christina and Kisha pooled their money together to buy
methamphetamine at a better price from Perales. One of Kisha’s customers
was Bowen, who gave her money to purchase methamphetamine for him from
Perales.    Eventually, Kisha and Christina introduced Bowen to Perales
because Bowen had “a lot” of customers and was having trouble getting his
supply from Salazar’s agents.
      Perales testified that he sold two to four ounces of methamphetamine to
Kisha and Bowen per week.            Perales testified that after Kisha stopped
participating, Bowen continued to buy methamphetamine from Perales, and
eventually brought Tibbs with him. Bowen and Tibbs pooled their money to
buy methamphetamine from Perales. According to Perales, Tibbs and Bowen
eventually purchased around ten ounces per week from him. Perales testified
that he knew Tibbs and Bowen were distributing methamphetamine in
Sherman.
      Marie Davila testified that she purchased methamphetamine from
Bowen and that beginning in summer 2011, she was paid by Bowen to drive
him to pick up drugs from Perales. She testified that Bowen paid her $100
cash and a gram of methamphetamine for each trip. Carlos Cabrales, who
lived with Davila, testified that he was paid to supply Davila with a car to drive
Bowen and also to rent cars for them so that Bowen could pick up drugs in a
variety of cars.

      2 Kisha Bowen is Appellant Bowen’s sister-in-law. All references to “Bowen” in this
opinion are to Appellant Timothy Bowen.

                                No. 14-40654

      Davila testified that Bowen purchased “two sandwich bags” half-full of
methamphetamine about every two days from Perales until about mid-October
2011. Davila testified that in the approximately three-month period during
which Davila drove Bowen, they made eighteen to twenty trips to buy drugs
from Perales.   Davila testified that she also helped Bowen package the
methamphetamine for redistribution to Bowen’s customers and would rent
hotel rooms, which Bowen paid for, where she and Bowen would package the
drugs.
      In sum, the evidence at trial demonstrated that Primo sent
methamphetamine from Mexico via Cazares and Vega, who delivered the
drugs to Nguyen in Dallas.      Nguyen sold the methamphetamine to the
Camacho siblings in Dallas. The Camacho siblings sold methamphetamine to
Salazar and his partner House.          Salazar and House also bought their
methamphetamine from Perales in Dallas, and once Salazar and House went
to jail, some of their customers also bought methamphetamine from Perales.
Salazar,   House,    and   some    of       their   customers     distributed    the
methamphetamine in the Sherman/Denison area.                    Bowen purchased
methamphetamine from Salazar and, once Salazar went to jail, from Perales
(first through Kisha Bowen and Christian House, then directly from Perales,
sometimes pooling his money with Tibbs to get a better deal from Perales), and
sold that methamphetamine to customers in the Sherman area.
      When the government rested after the presentation of the evidence,
Appellants moved for acquittal. After hearing argument from each Appellant’s
counsel, the district court denied the three motions for acquittal. Appellants
then waived their right to testify, and defense counsel rested. Appellants
requested a multiple conspiracies instruction, which the district court denied.
The jury found all three Appellants guilty of the charged crime. Vega and

Bowen were sentenced to 324 months of imprisonment, and Salazar was
sentenced to life imprisonment.
       All three Appellants appeal their convictions, and Bowen appeals his
sentence as well. Regarding the challenges to the convictions, Bowen and Vega
argue that the evidence was insufficient to support their convictions; Salazar
and Bowen argue that the district court abused its discretion by refusing to
give the jury a multiple-conspiracies instruction; and Salazar argues that a
statement made by the prosecutor in closing argument was reversible error.
Regarding Bowen’s challenge to his sentence, Bowen argues that the district
court impermissibly granted a three-level enhancement for Bowen’s role as a
manager/supervisor in the conspiracy and that the district court impermissibly
calculated his base offense level using the conspiracy-wide drug quantity,
rather than a drug amount for which Bowen was individually responsible.

                                        A.
       Vega and Bowen argue that the government’s evidence was insufficient
to support their convictions. Because Vega and Bowen made timely motions
for acquittal at trial, we review de novo their challenge to the sufficiency of the
evidence supporting their convictions. United States v. Beacham, 774 F.3d 267,
272 (5th Cir. 2014).    The review, though de novo, is nevertheless “highly
deferential to the verdict.” Id. “The jury’s verdict will be affirmed unless no
rational jury, viewing the evidence in the light most favorable to the
prosecution, could have found the essential elements of the offense to be
satisfied beyond a reasonable doubt.” United States v. Roetcisoender, 792 F.3d
547, 550 (5th Cir. 2015). While we consider evidence that countervails the
jury’s verdict, all reasonable inferences are made in favor of the jury’s verdict.

      To prove a drug conspiracy, the government must prove that “(1) two or
more persons, directly or indirectly, reached an agreement to possess with the
intent to distribute a controlled substance; (2) [the defendant] knew of the
agreement; (3) [the defendant] voluntarily participated in the agreement; and
(4) the overall scope of the conspiracy involved [the drug amount in the charged
crime].” United States v. Castillo-Chavez, 555 F. App’x 389, 398–99 (5th Cir.
2014) (citing United States v. Jimenez, 509 F.3d 682, 689 (5th Cir. 2007)); 21
U.S.C. §§ 841(a)(1), (b)(1)(A), and 846), cert. denied, 135 S. Ct. 161 (2015). “A
reasonable jury may ‘infer the existence of a conspiracy from the presence,
association, and concerted action of the defendant with others.’” Id. (quoting
United States v. Curtis, 635 F.3d 704, 719 (5th Cir. 2011)).
      Vega argues that the evidence against him was “solely based on the co-
defendant testimony of one witness, Mr. Ramiro Cazares.” Vega acknowledges
that a co-conspirator’s uncorroborated testimony can support a guilty verdict—
even if the co-conspirator has accepted a plea bargain—unless the testimony
is “incredible.” See United States v. Villegas-Rodriguez, 171 F.3d 224, 228 (5th
Cir. 1999). Vega argues that Cazares’s testimony is incredible because Cazares
admitted to being a deceptive person and had a motive to testify against Vega
for the possibility of a reduced sentence.
      “Testimony is incredible as a matter of law only if it relates to facts that
the witnesses could not possibly have observed or to events which could not
have occurred under the laws of nature.” United States v. Valdez, 453 F.3d
252, 257 (5th 2006). Neither Cazares’s admission to having deceived someone
in the past nor his possible motive to testify against Vega render Cazares’s
testimony “incredible.” See id. The jurors were adequately informed about
these matters, and we do not review the weight or credibility of the evidence,
including witness testimony. United States v. Hayes, 342 F.3d 385, 389 (5th

                                        7

                                    No. 14-40654

Cir. 2003). Instead, we view the evidence “in the light most favorable to the
verdict, accepting all credibility choices and reasonable inferences made by the
trier of fact which tend to support the verdict.” United States v. Moreno-
Gonzalez, 662 F.3d 369, 372 (5th Cir. 2011).
      Moreover, the premise of Vega’s argument is simply incorrect.               The
evidence against Vega was not “solely based” on Cazares’s testimony—Agent
Mata also testified against Vega.             Agent Mata corroborated Cazares’s
testimony by testifying about physical evidence, including evidence that linked
Vega to the crime, and about Vega’s incriminating statements made to Agent
Mata after Vega’s arrest.      For example, Agent Mata testified that during
surveillance of Vega’s apartment in Dallas, they observed Vega driving the
black Honda Accord with the hidden compartments that, according to trial
testimony, one of Nguyen’s agents gave to Cazares for drug runs. 3 Agent Mata
also testified that after arresting Vega, Vega told him that Cazares’s source
was “Primo”; admitted to being a “runner” for Cazares; stated that there were
multiple kilograms of methamphetamine in a basket upstairs in Cazares’s ex-
wife’s house in Grand Prairie—precisely where agents had just previously
recovered multiple kilograms of methamphetamine; stated that he knew the
Black Honda had a hidden compartment and that Cazares had loaned the car
to him; and, after denying that he had the keys to the Honda, eventually
admitted that the keys were hidden inside a speaker box in his apartment,
which was were agents found the keys. Vega also told Agent Mata that he had
had a cell phone, but he had thrown it on the side of the road after hearing that
Cazares had been arrested.

      3 Specifically, Manuel Urbina testified that he worked for Nguyen in the
methamphetamine distribution scheme and had worked with Cazares to transport drugs and
drug proceeds. Urbina testified that he delivered the Honda Accord with the hidden
compartments to Cazares at the direction of Nguyen. Nguyen testified that he bought the
Honda Accord and put a drug stash box in it that was accessed via a trapdoor.

                                          8
    Case: 14-40654      Document: 00513442554        Page: 9    Date Filed: 03/29/2016

                                    No. 14-40654

      The jury also heard a recorded phone call between Vega and Cazares
that corroborated Cazares’s testimony. According to Cazares, he and Vega had
transported six kilograms of methamphetamine to Cazares’s house and had set
up a lab to make “ice” by “cooking” the methamphetamine. 4 During the phone
call, Vega referred to the “cooking” and offered to “do the cooking” that day.
Cazares told Vega that he was still waiting to hear from Primo, and Vega
indicated that he knew about Primo and knew Primo was in charge. Cazares
also told Vega that he wanted to get the “balls” out of the house, and Vega
responded by offering to help Cazares find a place to “store it for good.”
      This evidence was sufficient to show that Vega knew about the
methamphetamine distribution scheme and voluntarily agreed to act in
furtherance of that scheme. See Jimenez, 509 F.3d at 689. As far as Vega’s
connection to the conspiracy as a whole, various witnesses testified to
Cazares’s connections to Primo and Nguyen, and to Primo and Nguyen’s
connections to the Camacho siblings, who supplied methamphetamine to
Salazar, who sold methamphetamine in the Sherman/Denison area, including
to Bowen who distributed methamphetamine to his own customers in the
Sherman/Denison area.           Finally, the testimony of multiple witnesses
established that the conspiracy easily involved the charged quantity of
methamphetamine. 5       The evidence was easily sufficient to support Vega’s
conviction.

      4    Agent Mata testified that “cooking” is the term for converting powder
methamphetamine to crystal methamphetamine.
        5 Andy Nguyen testified that he sold the Camacho siblings around twenty to thirty

kilograms of methamphetamine. Manuel Camacho testified that he delivered to House on a
single occasion two pounds of methamphetamine, which equates to over 900 grams. Manuel
Camacho estimated that, in all, from mid-2010 to when he was arrested in 2012, he sold
roughly 43.5 pounds (19,731.27 grams) to Salazar and House. Manuel Camacho testified
that all of that methamphetamine was distributed in the Sherman/Denison area.

                                  No. 14-40654

      Turning to Bowen’s sufficiency argument, Bowen argues that the
evidence against him did not show he was a member of the methamphetamine
distribution conspiracy because there was no evidence that Bowen “entered
into an agreement with anyone to distribute methamphetamine.”              Bowen
argues that he acted “independently” of the other co-conspirators because he
“did not depend on anyone other than himself.” Bowen also argues that the
evidence against him was based solely on the testimony of cooperating
witnesses and their testimony was “wholly unbelievable or [un]reliable” or
“incredible as a matter of law” because the witnesses’ testimony was
inconsistent as to the dates when Bowen allegedly met Perales and Salazar to
purchase methamphetamine, as some witnesses said June 2011, while others
said September 2011.
      An express agreement is not required to prove a conspiracy: “It is well-
settled that circumstantial evidence may establish the existence of a
conspiracy, as well as an individual’s voluntary participation in it,” and a “jury
is free to infer the existence of a conspiracy from the presence, association, and
concerted action of the defendant with others.”        Curtis, 635 F.3d at 719
(internal quotation marks and alterations omitted). The evidence showed
many instances in which Bowen depended on other co-conspirators, such as his
buying methamphetamine from Salazar and Perales, giving Kisha Bowen and
Christina House money to buy methamphetamine for him from Perales, and
pooling his money with Tibbs to get a better deal on methamphetamine from
Perales. Finally, discrepancies in witness testimony go to the weight and
credibility of the evidence, which we do not review. Moreno-Gonzalez, 662 F.3d
at 372 (“[A]ny conflict in the evidence must be resolved in favor of the jury's
verdict.”).

                                  No. 14-40654

      The evidence was more than sufficient to show that Bowen knew about
the methamphetamine distribution scheme and voluntarily took part in the
scheme: multiple witnesses testified that Bowen cooperated with many of the
alleged co-conspirators—including Perales, Salazar, Kisha Bowen, Christina
House, and Tibbs—to buy and distribute methamphetamine in the
Sherman/Denison area. For example, Bowen bought methamphetamine from
Salazar until Salazar went to jail, after which he gave money to Kisha Bowen
and Christina House to buy methamphetamine for him from Perales, to whom
Bowen was eventually introduced because Bowen needed a good source to
supply his customers in the Sherman/Denison area. Marie Davila testified
that Bowen sold drugs to her and later paid her to drive him to buy drugs from
Perales after which Davila helped Bowen package the methamphetamine for
redistribution in the Sherman/Denison area. Tibbs testified that Bowen pooled
his money with him so that they could get a better deal on methamphetamine
from Perales. Accordingly, Bowen’s sufficiency challenge also fails. 6
                                        B.
      Salazar and Bowen argue that their convictions must be reversed
because the trial court failed to give a multiple conspiracies jury instruction.
Where, as here, the defense requested a jury instruction and the request was
denied, we review the denial for abuse of discretion.            United States v.
McClatchy, 249 F.3d 348, 356 (5th Cir. 2001). The court affords “substantial
latitude to the district court in describing the law to the jury.” United States
v. Barnes, 803 F.3d 209, 222 (5th Cir. 2015).
      A multiple conspiracies instruction “is generally required where the
indictment charges several defendants with one . . . overall conspiracy, but the

      6  As discussed above, the charged conspiracy-wide quantity was established by
witness testimony. See supra note 5.

                                        11
    Case: 14-40654        Document: 00513442554          Page: 12      Date Filed: 03/29/2016

                                        No. 14-40654

proof at trial indicates that some of the defendants were only involved in
separate conspiracies unrelated to the overall conspiracy charged in the
indictment.” United States v. Castaneda-Cantu, 20 F.3d 1325, 1333 (5th Cir.
1994) (second emphasis added). Salazar and Bowen argue that Bowen was in
only a separate conspiracy unrelated to the drug dealing activities of Salazar
and other co-conspirators because Bowen acted “independently” of the other
conspirators.
       Ordinarily, district courts should give a multiple conspiracies instruction
if there is some evidence that could support a reasonable jury’s finding that the
defendant was in only an unrelated conspiracy. The government argues that
here there is no such evidence that Bowen was in only an unrelated conspiracy.
Assuming, arguendo, that there was such evidence, any error was harmless
because: (1) the jury was given a detailed conspiracy instruction requiring
them to find that Bowen was a member of the charged conspiracy; (2) Bowen’s
counsel was free to, and did, argue that Bowen was not part of the charged
conspiracy; and (3) the evidence against Bowen was overwhelming. 7                          See

       7  In United States v. Erwin, 793 F.2d 656, 663 (5th Cir. 1986), we reversed a district
court’s refusal to give a multiple conspiracy instruction without expressly analyzing whether
substantial prejudice required reversal. Our earlier case law indicates that a prejudice
analysis is required for reversal. See, e.g., United States v. LeCompte, 599 F.2d 81, 82 (5th
Cir. 1979) (holding that the trial court did not err by failing to instruct on multiple
conspiracies when the refusal did not prejudice the defendants). And our “later caselaw has
effectively by-passed” that omission in Erwin. United States v. Frame, 236 F. App’x 15, 18
(5th Cir. 2007); see, e.g., United States v. Johnson, 68 F.3d 899, 904 (5th Cir. 1995) (requiring
defendant-appellant to show that the refusal to give a multiple conspiracies instruction
“seriously impaired the defendant’s ability to present a given defense” and affirming the
district court because “[t]he charge given by the trial court adequately instructed the jury
that it could not convict [the defendant] unless the government proved beyond a reasonable
doubt that the defendant knowingly joined in the conspiracy described in the indictment” and
because appellant’s “defense could not have been seriously impaired by the district court’s
refusal to give the proposed charge”); United States v. Segura, 122 F. App’x 768, 780 (5th Cir.
2005) (requiring a prejudice analysis when determining whether the trial court erred for
failure to instruct the jury on multiple conspiracies defense); cf. United States v. Saldivar, 48

       Salazar also argues that his conviction should be reversed because one
of the prosecutor’s statements during closing argument constituted improper
vouching for the credibility of government witnesses who had testified
pursuant to plea agreements.              “The test for improper vouching for the
credibility of a witness is ‘whether the prosecutor’s expression might
reasonably lead the jury to believe that there is other evidence, unknown or
unavailable to the jury, on which the prosecutor was convinced of the accused’s
guilt.’” United States v. McCann, 613 F.3d 486, 495 (5th Cir. 2010) (quoting
United States v. Ellis, 547 F.2d 863, 869 (5th Cir. 1977)). Salazar contends
that the italicized portion of the following statement during the prosecutor’s
rebuttal argument constituted improper bolstering of government witness
testimony and was unsupported by any evidence at trial:
             . . . [W]hen you are considering the testimony of a person
       who comes into this courtroom, who did you think was gonna come
       in here and testify? . . . Not choirboys, not preachers. It’s gonna
       be the people that are involved. And that’s who we brought you.
       Now, you have to decide whether they’re credible or not; you have
       to decide whether you believe them or not.

indictment and proof regarding a single or multiple conspiracy that “[a] variance between the
indictment and proof is not fatal unless it prejudiced the defendant’s substantial rights”).
       Here, the jury was given a detailed instruction on conspiracy, and Bowen’s defense
counsel argued a multiple conspiracies theory to the jury. Bowen was not substantially
prejudiced by the trial court’s failure to give a multiple conspiracies instruction. See Johnson,
68 F.3d at 904; Ary-Berry, 424 F. App’x at 351 (citing United States v. Storm, 36 F.3d 1289,
1294 (5th Cir. 1994)).

Case: 14-40654    Document: 00513442554       Page: 14   Date Filed: 03/29/2016

                              No. 14-40654

        And we did go over the plea agreements ad nauseam. And
  we do that because we want you to see the restrictions and
  conditions that they’re under when they testify. We want you to
  see that if they lie, there are consequences.
         And how are we going to know that they’re lying to us? We’re
  gonna know that because the people that testify that are giving us
  information, they don’t know what we know. They don’t know who
  we’ve talked to. So if we’re talking to individuals and they differ
  between one another, and we’re telling them, “You have to be 100
  percent honest,” and we’ve heard different stories from those people,
  then they’re gonna be called to task for it. Because they’re being
  interviewed at separate times, and the information that the agent
  has developed through his investigation that he knows, and the
  information that he has developed by debriefing other people, not
  only the one that’s giving the information, that he knows is going to
  be used as a barometer to tell us whether that person is telling us
  the truth or not. . . . [Y]ou saw the conditions that are in the plea
  agreement, that if they don’t testify, other charges can be filed
  against them, obstruction of justice, perjury, and that would be
  stacked on top of the time that they’re already looking at. So ask
  yourself: If the goal is to do less time, if the goal is to be with your
  infant child, then it makes no sense for them to come in here and
  lie to you, where they would be exposed to more time. . . .
         So, yes, there has to be some incentive for them to come in
  here and testify, because nobody wants to come in here and testify
  and point someone out and say, ‘that’s the guy that was selling to
  me.’ . . . No one wants to do that. . . .
        So is there any guarantees or promises made to them? No.
        Is there a hope that they may receive something? Yes.
        And they all said that repeatedly. That’s the information
  that you have, ladies and gentlemen, to judge their credibility. We
  didn’t hide their addictions, we didn’t hide their criminal history,
  because we want you to take all of that into consideration. But
  mostly what we want you to do is for you to take their testimony,
  compare it to another person’s testimony that came into this
  courtroom, and see that their testimony matches.

Salazar notes, quoting our decision in United States v. Gracia, that a
prosecutor “may not make a personal assertion regarding a government
witness’s credibility, cloaking the witness in the Government’s ‘protective
mantle.’” 522 F.3d 597, 600–01 (5th Cir. 2008). Salazar argues that because
the entirety of the evidence against him was based on the testimony of
government witnesses, the prosecutor’s statement—assuring the jury that the
government witnesses were truthful because their testimony had been
compared with other informants’ statements—was an improper bolstering of
witness testimony that casts serious doubt on the jury’s verdict.
      As we have repeatedly observed, “[a] prosecutor is confined in closing
argument to discussing properly admitted evidence and any reasonable
inferences or conclusions that can be drawn from that evidence.” United States
v. Ceballos, 789 F.3d 607, 624 (5th Cir. 2015) (quoting United States v. Reagan,
725 F.3d 471, 492 (5th Cir. 2013)). “We have repeatedly chastised federal
prosecutors for making improper remarks in closing arguments—for example,
for ‘bolstering’ federal agents’ credibility in closing arguments, for attacking
the character of the defendant, and for attacking the character of defense
counsel.” United States v. Rodriguez-Lopez, 756 F.3d 422, 433–34 (5th Cir.
2014) (citing United States v. Aguilar, 645 F.3d 319, 324 (5th Cir. 2011); United
States v. Jefferson, 432 F. App’x 382, 390 (5th Cir. 2011); United States v.
Murrah, 888 F.2d 24, 27 (5th Cir. 1989)). In particular, “[e]xcept to the extent
the prosecutor bases any opinion on the evidence in the case, he may not
express his personal opinion on the merits of the case or the credibility of
witnesses.” Ceballos, 789 F.3d at 624 (quoting United States v. Alaniz, 726
F.3d 586, 616 (5th Cir. 2013)).
      The prosecutor’s closing argument in this case constituted improper
vouching. The prosecutor argued in closing that government witnesses should

                                       15
   Case: 14-40654    Document: 00513442554     Page: 16   Date Filed: 03/29/2016

                                No. 14-40654

be credited because they would be “called to task” pursuant to their plea
agreements for any dishonesty—dishonesty which the government was
positioned to identify based on “the information that the agent has developed
through his investigation that he knows, and the information he has developed
by debriefing other people.” That comment “might reasonably lead the jury to
believe that there is other evidence, unknown or unavailable to the jury,” on
which the prosecutor was basing his argument as to the witnesses’ credibility.
See McCann, 613 F.3d at 495. We are not persuaded by the government’s
response that the challenged statement was a permissible rebuttal to Bowen’s
closing argument, in which Bowen’s attorney argued that the government
would have no way of knowing whether witnesses were lying so as to enforce
those witnesses’ plea agreements.      While we have sometimes permitted
bolstering arguments that specifically respond to attacks on witness
credibility, such arguments must draw only on evidence before the jury. See
id. at 495–96. Here, the jury was not exposed to “the information that the
agent ha[d] developed through his investigation,” and the prosecutor’s
credibility argument based on that information was consequently improper.
      Although the challenged statement was improper, it did not “cast serious
doubt on the correctness of the jury’s verdict.” United States v. Anderson, 755
F.3d 782, 797 (5th Cir. 2014). The conviction was supported by overwhelming
evidence of Salazar’s guilt. See id. at 798–99; Rodriguez-Lopez, 756 F.3d at
434. Nearly every witness throughout the seven-day trial, including several
who had not entered into plea agreements with the government, testified to
Salazar’s significant involvement in the methamphetamine distribution
conspiracy. Salazar is not entitled to a new trial based on the prosecutor’s
improper closing argument.

        Bowen argues that his sentence should be vacated because the district
court improperly granted a three-level enhancement for Bowen’s role as a
manager/supervisor in the conspiracy when the evidence did not support the
enhancement.
        We review the district court’s interpretation and application of the
sentencing guidelines de novo and its findings of fact for clear error.
Roetcisoender, 792 F.3d at 550. When determining whether an enhancement
applies, “a district court is permitted to draw reasonable inferences from the
facts, and these inferences are fact-findings reviewed for clear error as well.”
United States v. Pillault, 783 F.3d 282, 286–87 (5th Cir. 2015). The district
court’s factual finding “is not clearly erroneous if it is plausible in light of the
record read as a whole,” or, put another way, a district court’s factual findings
will be held clearly erroneous “only if, based ‘on the entire evidence,’ we are
‘left with the definite and firm conviction that a mistake has been committed.’”
Id.
        Under § 3B1.1(b) of the U.S. Sentencing Guidelines, a defendant’s base
offense level should be increased by three levels if the defendant “was a
manager or supervisor (but not an organizer or leader) and the criminal
activity involved five or more participants or was otherwise extensive.”
U.S.S.G. § 3B1.1(b). The Guidelines do not define “manager” or “supervisor,”
but the commentary notes state that the defendant “must have been . . . the
manager, or supervisor of one or more other participants.” United States v.
Nava, 624 F.3d 226, 229 (5th Cir. 2010) (citing § 3B1.1 cmt. n.2 (2009)). Bowen
argues that the district court’s finding that he was a manager/supervisor in
the conspiracy was clearly erroneous because there was no evidence that
Bowen forced Davila or Cabrelas to work for him. Bowen also argues that

                                        17
    Case: 14-40654        Document: 00513442554           Page: 18     Date Filed: 03/29/2016

                                        No. 14-40654

because Davila and Cabrelas never sold drugs or collected drug money for him,
Bowen cannot be considered a manager/supervisor.
       At sentencing, the district court found that the evidence at trial showed
that Bowen was hiring individuals to drive him to pick up drugs, to rent cars
for those pick-ups, and to rent hotel rooms where the drugs would be packaged
for distribution, and that such evidence supported a finding that Bowen acted
in a managerial role in the conspiracy. We agree. Accordingly, it was not error
for the district court to enhance Bowen’s offense level for his role as a
manager/supervisor. 8
                                              III.
       Because we find no reversible error in Appellants’ convictions or Bowen’s
sentence, we AFFIRM.

       8 In a 28(j) letter filed after the completion of briefing, Bowen also argued for the first
time that in light of our recently published decision in United States v. Haines, 803 F.3d 713
(5th Cir. 2015), his sentence should be vacated because the district court based its Guidelines
calculation on the drug quantity attributable to the conspiracy as a whole rather than to him
individually. We have made clear that any issue not raised in an appellant’s opening brief is
forfeited. See United States v. Delgado, 672 F.3d 320, 348–49 (5th Cir. 2012). Moreover,
Haines is inapposite because in it “[w]e simply [held] that, for purposes of statutory
minimums at sentencing, the relevant quantity is the quantity attributable to the individual
defendant,” Haines, 803 F.3d at 742, whereas here, Bowen does not challenge the calculation
of his mandatory minimum sentence but rather his offense level under the Guidelines.
