PER CURIAM.

      The Government tried Ulises Ariel Lopez and Israel Gonzales-Lara together
on charges arising out of a drug conspiracy that took place in Des Moines, Iowa.
Lopez appeals his convictions after a jury found him guilty of conspiring to distribute
methamphetamine and of possessing methamphetamine with intent to distribute. See
21 U.S.C. §§ 841(a)(1); 841(b)(1)(A); and 846. Lara appeals his conviction and
sentence after a jury found him guilty of conspiring to distribute methamphetamine.
See 21 U.S.C. §§ 841(a)(1) and 846. We consolidated the appeals. For reversal,
Lopez argues that the district court erred by admitting hearsay evidence. Lara raises
additional claims of error that he argues rendered his trial fundamentally unfair.
Lastly, Lara argues that the district court erred in enhancing his offense level for
possessing a firearm. For the following reasons, we affirm Lopez's and Lara's
convictions and Lopez's sentence. We vacate the enhancement to Lara’s sentence for
possession of a firearm and remand his sentence for further consideration.

I.    Background

       We recite the facts in the light most favorable to the jury’s verdict. See United
States v. McCracken, 

, 540 (8th Cir. 1997). Felix Baccam and Israel
Gonzales-Lara a/k/a Isaac Ramos met at a Des Moines, Iowa night club in May of
2002. During their encounter, Baccam expressed interest in distributing
methamphetamine and Lara agreed to supply Baccam with methamphetamine.
According to the agreement, Lara would “front” Baccam the methamphetamine and
would receive payment after Baccam sold it to his buyer, Joe Hernandez. At first,
Lara provided Baccam with one pound of methamphetamine every seven to ten days.
After a few months, Baccam requested more methamphetamine and Lara provided
him with two pounds every seven to ten days. A short time later, Baccam informed

                                          -2-
Lara that he could sell additional amounts of methamphetamine. Lara increased the
amount he provided to three pounds. At the first three-pound delivery, Lara
introduced Baccam to his supplier, Ulises Ariel Lopez. Baccam paid Lara in cash for
the previous delivery and Lara gave the money to Lopez.

      Unbeknownst to Baccam, police arrested his buyer, Hernandez, on simple
possession charges. In cooperation with the police department, Hernandez told police
he bought methamphetamine from Baccam. He provided the police with information
about past drug transactions including the location of the transactions and a
description of the vehicle Baccam drove to the transactions. He arranged to meet
Baccam for another delivery and police set up surveillance at the location.

       On October 2, 2002, Lopez accompanied Lara to deliver another three pounds
of methamphetamine to Baccam. Lara gave the methamphetamine to Baccam.
Baccam left to deliver the methamphetamine to his buyer and Lopez accompanied
him. Police stopped Baccam’s vehicle when it approached the location. The police
recovered three pounds of methamphetamine from the floor behind the passenger seat
and a loaded .380 caliber pistol from under the driver's seat. The police arrested both
Baccam and Lopez. Later that evening, police arrested Lara on unrelated charges and
took him to the Polk County Jail, where police later learned of Lara’s participation
in the conspiracy.

       The Grand Jury returned a three-count indictment. Count one charged Lara,
Lopez and Baccam with conspiracy to knowingly and intentionally distribute
methamphetamine in violation of 21 U.S.C. §§ 841(b)(1)(A) and 846. Count two
charged Lopez and Baccam with possession with intent to distribute
methamphetamine in violation of 21 U.S.C. § 841(a)(1). Count three charged
Baccam with possession of a firearm in relation to a drug trafficking crime in
violation of 18 U.S.C. § 924(c)(1)(A). Baccam pleaded guilty to counts two and three
and testified at trial against Lara and Lopez.

                                         -3-
       Shawn Miller, Lara’s cellmate, also testified at trial. Miller testified that while
in the cell together, Lara described his role in a drug conspiracy with two other
individuals. Lara told Miller that he acted as the middleman between Lopez and
Baccam, receiving methamphetamine from Lopez and then giving it to Baccam to
distribute. Lara also told Miller that he had six to eight more pounds of
methamphetamine that he needed to unload. Miller agreed to help Lara get rid of the
remaining methamphetamine. According to Miller, Lara’s girlfriend deposited
$1,400 in Miller’s account to secure his cooperation in disposing of the drugs. Lara’s
girlfriend and Lara testified that she deposited the money as security for renting
Miller’s apartment.

       Lara’s attorney argued during opening statements that another individual
named Isaac Ramos, not Lara, participated in the conspiracy with Baccam and Lopez.
To support the argument Lara introduced testimony from Paul Feddersen, a state drug
investigator. During the course of one of Feddersen’s investigations he spoke to a
man named Isaac Ramos by telephone. The Isaac Ramos that Feddersen spoke with
had an Asian accent; Lara is Mexican. However, when officer Feddersen arrived to
testify he brought with him a videotape showing Lara with the other drug
conspirators. Before testifying, Feddersen showed the video to Lara and the
Government. Despite the videotape, Lara presented Feddersen’s testimony. The
Government presented the video on cross-examination. Other witnesses, including
Lara’s girlfriend, testified that Lara used the name Isaac Ramos on many occasions.

      The jury returned a guilty verdict on count one for both Lara and Lopez and
count two for Lopez. The jury found beyond a reasonable doubt that the quantity of
drugs possessed during the course of the conspiracy exceeded fifty grams of actual
methamphetamine or 500 grams of a mixture or substance containing
methamphetamine, but no further quantity determination was proved to the jury.




                                           -4-
        The presentence investigation reports for Lopez and Lara recommended a base
offense level of 36. The level reflected the amounts of methamphetamine attributed
to the conspiracy by the Government’s main witnesses, Baccam and Miller. The pre-
sentence investigation reports also recommended that both Lopez and Lara receive
a two-level enhancement for possession of a firearm by Baccam, a co-conspirator,
pursuant to U.S.S.G. §§ 1B1.3(a)(1)(B) and 2D1.1(b) and a two-level enhancement
for obstruction of justice pursuant to U.S.S.G. § 3C1.1 because both dishonestly
testified on their own behalf during trial.

      Lopez and Lara objected to the calculation of the base offense and argued that
the amount attributed to the conspiracy be restricted to the amount seized by police
when they arrested Baccam. The amount seized would support a base offense level
of 32. See U.S.S.G. § 2D1.1(c). Lopez and Lara also objected to the firearm
enhancement and Lara objected to the obstruction of justice enhancement.

      The district court used a base level of 36 based on its calculation of the drug
quantity described in Baccam’s testimony. The district court applied the firearm
enhancement to both Lara and Lopez but only applied the obstruction of justice
enhancement to Lopez. The court sentenced Lopez to a term of 292 months
imprisonment and Lara to a term of 235 months imprisonment. Lara and Lopez
timely appealed.

II.   Discussion

      A.     Lopez’s Conviction

      Lopez argues that the district court erred by allowing Miller’s testimony to be
introduced against him. We review a district court’s decision to admit a co-
conspirator’s statement for abuse of discretion and reverse if the error substantially
prejudiced the outcome. See United States v. Frazier, 

, 848 (8th Cir.

                                         -5-
2002) and United States v. Beckman, 

, 522 (8th Cir. 2000). Rule
801(d)(2)(E) of the Federal Rules of Evidence allows a statement that would
otherwise be hearsay to be admitted if a co-conspirator made the statement “during
the course and in furtherance of the conspiracy.” Lara approached Miller and asked
him to dispose of methamphetamine. At this time, Miller became Lara’s co-
conspirator. Miller’s testimony regarding statements made by Lara in furtherance of
the conspiracy fall within the hearsay exception when introduced to show Lara’s
involvement in the conspiracy. The district court can properly admit evidence
implicating one co-conspirator even if the evidence prejudices the other co-
conspirator if it gives the jury a limiting instruction. See United States v. Frazier, 

, 844 (8th Cir. 2002).

        Regardless of whether the district court properly admitted Miller’s testimony,
we do not reverse because the error did not prejudice the outcome of the case. “An
error is harmless if the reviewing court, after viewing the entire record determines
. . . the error did not influence or had only a very slight influence on the verdict.”
United States v. Hafiz, 

, 1012 (8th Cir. 1997) (citation omitted). Police
arrested Lopez and Baccam en route to deliver drugs to Joe Hernandez. Police found
three pounds of methamphetamine in the car directly behind Lopez on the floor
behind the passenger seat. Additionally, Felix Baccam testified at trial that Lopez
provided the drugs to Lara and that Lara paid Lopez for the drugs. Even without
Miller’s testimony, the jury had enough evidence to find Lopez guilty. Therefore, we
affirm Lopez’s conviction.

      B.     Lara’s Conviction

       Lara makes several arguments for reversal related to the district court’s rulings
on evidentiary matters that require little attention. Lara argues that the district court
(1) erred by allowing Miller to testify about conversations he had with Lara’s
girlfriend, (2) erred by failing to strike Lara’s aliases from court documents, (3) erred

                                           -6-
by refusing to admit documents showing criminal convictions of the Government’s
witnesses and (4) erred by allowing the Government to present the videotape because
the Government improperly withheld the tape from him which prevented him from
preparing a proper defense.

        We review evidentiary rulings for abuse of discretion and reverse only when
an erroneous ruling prejudices the outcome of the case. See United States v. Ball,

, 987 (8th Cir. 1989) and United States v. Kirkie, 

, 767
(8th Cir. 2001). The district court’s evidentiary rulings in this case did not prejudice
the outcome and therefore require little discussion. Prejudice results when an
erroneous evidentiary ruling affects the substantial rights of the defendant or when
the error has a significant impact on the verdict. See United States v. Kirkie, 

(8th Cir. 2001). Even if the district court erred, as Lara argues, the
cumulative effect of the error did not outweigh the overall impact the inculpatory
evidence presented by the Government had on the ultimate verdict. Felix Baccam
testified at trial that Lopez provided the drugs to Lara and that Lara paid Lopez for
the drugs. He also testified that he bought methamphetamine from Lara on numerous
occasions. Additionally, Shawn Miller testified that Lara told him about his
involvement with Baccam and Lopez. Lara asked Miller to dispose of the remaining
methamphetamine and paid him $1,400 to do so. This properly admitted evidence,
taken as a whole, could suffice to convince a reasonable jury of Lara’s guilt. If
indeed the district court made erroneous evidentiary rulings, the rulings did not harm
the outcome of the case.

       Lara also argues that the district court erred by failing to submit his requested
instruction to the jury. We review the district court’s decision to withhold requested
jury instructions for abuse of discretion. United States v. Beckman, 

,
520 (8th Cir. 2000). Lara requested that the district court give the jury an option to
find that the Government had not proven its case. The district court declined and
ordered the jury to find Lara either guilty or not guilty. We give the district court

                                          -7-
considerable discretion in formulating jury instructions. United States v. Richmond,

, 1195 (8th Cir. 1983). We will not reverse a conviction when the jury
instructions given to the jury correctly stated the law. United States v. Paul, 

, 997 (8th Cir. 2000). The Eighth Circuit Model Jury Instructions allow for two
verdicts in a criminal trial: guilty and not guilty. See Eighth Circuit Manual of Model
Jury Instructions – Criminal Instruction 3.06. To our knowledge we have never
approved the use of a “not proven” verdict. Thus, it was within the district court’s
discretion to deny Lara’s jury instructions.

        Lara further argues that the district court erred in denying his motion for a
judgment of acquittal because the Government presented insufficient evidence. “In
reviewing a challenge to the sufficiency of the evidence, we may reverse a jury’s
verdict only where a reasonable fact-finder must have harbored reasonable doubt
relating to the government’s proof on at least one of the essential elements of the
offense.” United States v. Jensen, 

, 833 (8th Cir. 1998). We give the
jury’s verdict the benefit of reasonable inferences gathered from the record. 

conspiracy prosecution the Government must prove beyond a reasonable doubt (1)
that an agreement to achieve an illegal purpose existed, (2) that the defendant knew
about the agreement and (3) that the defendant knowingly became a part of the
agreement. See United States v. Ivey, 

, 383-84 (8th Cir. 1990). Lara
questions the credibility of Baccam and Miller. He argues that the Government did
not satisfy its burden of proof beyond a reasonable doubt because the witnesses
testified in order to receive leniency from the Government on their own charges.
“Jury verdicts are not lightly overturned.” United States v. Hood, 

, 129
(8th Cir. 1995). Although we have commented in the past on the often dubious
credibility of witnesses who testify in exchange for leniency from the Government,
see United States v. Aguilar-Portillo, 

, 747 (8th Cir. 2003), we can
neither weigh the evidence nor assess the credibility of the witnesses. United States
v. Stroh, 

, 440 (8th Cir. 1999).



                                          -8-
      Although the Government presented the jury with largely circumstantial
evidence, the evidence was sufficient for a reasonable jury to convict Lara. See
United States v. Wilcox, 

, 602-03 (8th Cir. 1995). With the use of
testimony from Baccam and Miller coupled with corroborating evidence, the
Government adequately showed that Lara entered into an agreement with Baccam and
Lopez to distribute methamphetamine. Baccam testified that Lara initiated an
agreement with him to supply methamphetamine. The Government also showed that
Baccam sold the methamphetamine that Lara provided to Hernandez on more than
one occasion and gave the money he received from the sales to Lara. Furthermore,
according to Miller’s testimony, Lara solicited him to join the conspiracy and help
unload the remaining methamphetamine. The verdict was supported by a credibility
assessment of Baccam's and Miller’s testimonies, and we cannot review the jury’s
assessment. We affirm Lara’s conviction.

      C.     Lara’s Sentence

      In Lara’s last argument, he contends that the district court erred by applying a
two-level sentencing enhancement for possession of a firearm by a co-conspirator.
He contends the district court incorrectly applied the enhancement because the
Government did not present sufficient evidence showing an adequate nexus between
him and the gun.

      Federal Sentencing Guideline § 2D1.1(b)(1) mandates a two-level sentencing
enhancement for any defendant who possesses a dangerous weapon in connection
with a narcotics crime. U.S.S.G. § 2D1.1(b)(1), app. n. 3 (2003). In order for the
enhancement to apply there must be “a temporal and spacial relation [] between the
weapon, the drug trafficking activity, and the defendant.” United States v. Payne, 

, 763 (8th Cir. 1996).




                                         -9-
       In United States v. Atkins, we upheld a § 2D1.1(b)(1) sentencing enhancement
when the defendant knew his co-conspirator possessed a gun and knew, based on past
experience, that his co-conspirator brought the gun along when delivering drugs. 

, 1213 (8th Cir. 2001). In contrast, when police arrested Baccam and
Lopez, Lara was across town in a hotel room. Police found the gun below the driver’s
seat in Baccam’s vehicle. The Government did not present any evidence that showed
Lara knew Baccam owned a gun. Nor did the Government present evidence that
showed Lara knew Baccam carried a gun when he delivered drugs to Hernandez.

      To support Lara’s sentence, the Government argues that we can infer a
defendant’s knowledge based solely on the nature of drug dealing. Cf. United States
v. Claxton, 

, 423 (8th Cir. 2002) (acknowledging the close connection
between firearms and drugs). We disagree. Under the Guidelines, a two-level
firearm enhancement can only be applied if the Government shows that the defendant
knew or should have known based on specific past experiences with the co-
conspirator that the co-conspirator possessed a gun and used it during drug deals. See
United States v. Highsmith, 

, 1142 (9th Cir 2001) (holding that the
firearm enhancement was not applicable where the defendant had access to the co-
conspirator’s weapon but did not know that the weapon existed). To hold otherwise
would unfairly penalize defendants for conduct over which they have no control.
Here the Government failed to present any evidence showing that Lara knew or
should have known that Baccam possessed a firearm. Thus, we unequivocally vacate
the two-level firearm enhancement for Lara and remand for resentencing.

III.   Conclusion

      As explained above, we affirm Lara's and Lopez's convictions. We also affirm
Lopez's sentence. Finally, we vacate Lara's enhancement for the possession of a
firearm and remand to the district court for resentencing and further consideration.



                                        -10-
      AFFIRMED IN PART, VACATED AND REMANDED IN PART.

BRIGHT, Circuit Judge, concurring and dissenting.

       I concur in affirming both Lara's and Lopez's convictions and vacating Lara's
sentence for further consideration. I dissent in affirming Lopez's sentence. Lopez has
filed a letter pursuant to Federal Rule of Appellate Procedure 28(j) calling our
attention to the United States Supreme Court's opinion in Blakely v. Washington,

(2004), and asserting that his sentence could be subject to adjustment.
In Blakely, the Court held that portions of the State of Washington’s sentencing
guidelines were unconstitutional because they deprived a defendant of his Sixth
Amendment right to “insist that the prosecutor prove to a jury all facts legally
essential to the punishment.” 

The district court has not had an
opportunity to consider the effect of Blakely on Lopez’s sentence. I would, therefore,
also remand Lopez's sentence to the district court for further consideration in light of
Blakely and its progeny.1
