          APPEAL FROM THE UNITED STATES DISTRICT COURT

                 FOR THE DISTRICT OF PUERTO RICO

         [Hon. Francisco A. Besosa, U.S. District Judge]

appellee.



                            August 1, 2013
             Per Curiam.    A jury convicted Antonio García-León of

conspiracy and aiding and abetting possession with intent to

distribute     controlled   substances.         García-León    appeals      his

conviction    on   the   grounds   that   the    evidence     at   trial    was

insufficient to support the jury's verdict because the government's

witnesses lied when they testified about his activities.                   Aside

from correcting a clerical error in the judgment as requested by

the parties, we affirm the conviction.

                              I. Background

             This case involves a drug trafficking organization that

operated in the Altos de Cuba Ward in Vega Baja, Puerto Rico.                 A

grand jury indicted García-León, along with seventy-three others,

for his participation in the organization.          The indictment stated

that García-León was a "runner," meaning that he was responsible

for distributing narcotics to sellers and collecting the proceeds

of drug sales.     García-León was charged with conspiracy and aiding

and abetting possession with intent to distribute cocaine, crack

cocaine, heroin, and marijuana within 1,000 feet of a school.

             At trial, the government called three witnesses who

testified that García-León had sold drugs in Altos de Cuba.                Each

of these witnesses had been charged with crimes related to the drug

trafficking organization, and each was promised that the prosecutor

would recommend a lower sentence in exchange for their testimony.

At the close of the government's case, and again at the close of


                                    -2-
evidence, García-León made both general and specific objections to

the sufficiency of the government's evidence.            The court denied

the Rule 29 motions.          The jury convicted both García-León and his

co-defendant, and García-León appealed.1

             On     appeal,   García-León   abandons   the   two   specific

objections he made at trial to the sufficiency of the government's

evidence.2        He argues instead that the evidence against him was

insufficient generally because it depended on incredible testimony

from government witnesses.

                                  II. Analysis

             The parties agree that the standard of review is de novo.

We have previously explained that there are good reasons to treat

a Rule 29 motion that raises both general and specific objections

as preserving all sufficiency challenges for de novo appellate


     1
      García-León's co-defendant, David Lopez-Ortiz, appealed
separately. We permitted Lopez-Ortiz's counsel to withdraw because
the appeal was frivolous, and we affirmed the conviction.      See
Anders v. California, 386 U.S. 738 (1967).
     2
      Arguably, García-León's brief mentions his original argument:
"[T]he grouping of numerous offenses through a given period of time
does not constitute the establishment of an agreement between
groups of individuals by itself for the entire span of the alleged
offenses committed." Even if this oblique statement refers to the
grounds for García-León's Rule 29 motion, it is not enough to
consider the argument to have been adequately presented on appeal.
See United States v. Zannino, 895 F.2d 1, 17 (1st Cir. 1990)
("[I]ssues adverted to in a perfunctory manner, unaccompanied by
some effort at developed argumentation, are deemed waived."). In
any event, the jury could have rationally credited the testimony of
the government witnesses as directly implying that García-León
intended to join and assist in the wider narcotic network in which
he actually participated.

review.    See United States v. Marston, 694 F.3d 131, 134-35 (1st

Cir. 2012).     Because García-León did precisely that and no party

urges a different standard, we review the denial of García-León's

Rule 29 motion de novo, construing the record evidence in the light

most favorable to the verdict.         Id.

            Although     García-León        asks     us   to   hold    that   the

government's witnesses did not tell the truth, we do not second-

guess the jury's assessment of a witness's credibility.                    United

States v. Paret-Ruiz, 567 F.3d 1, 5 (1st Cir. 2009).                     We have

recognized a narrow exception to this rule for a cooperating

accomplice's     "facially     incredible"         uncorroborated      testimony.

United States v. Rosario-Diaz, 202 F.3d 54, 67 (1st Cir. 2000).

            The testimony of the government's witnesses was not

facially incredible.      García-León contends that these witnesses--

Alfredo Sierra, Xiomara Rosado-Pabón, and Jesus Robles-Santana--

testified that he sold drugs or acted as a runner from 1999 to

2008, which would be impossible because he was incarcerated at

various times during that period, including the years 2003 and

2007. García-León mischaracterizes the witnesses' testimony. Each

witness testified about specific times during that period when they

saw García-León selling drugs (including times that he was out of

jail),    and   times   they   did   not.      For    example,   the    witnesses

testified that they did not see García-León in Altos de Cuba in

2007, which seems accurate because he was incarcerated then. While


                                      -4-
Sierra and Rosado-Pabón did testify incorrectly that García-León

sold drugs in 2003, Rosado-Pabón stated that she had very little

contact with him that year.          Moreover, the witnesses corroborated

each other's testimony on certain facts, such as the name of a

brand of cocaine that García-León sold.               The witnesses' mistakes

(or   even    lies,     if   they   were   lies)   regarding      García-León's

activities in 2003 do not make the rest of their testimony facially

incredible.3      See United States v. Washington, 434 F.3d 7, 14 (1st

Cir. 2006) ("The testimony of the cooperating co-defendants was

corroborated at trial, and [the appellant] has, at most, pointed

out minor inconsistencies that fall far short of rendering the

testimony facially incredible.").

             One final point requires our attention.               The parties

agree that the judgment erroneously failed to indicate that García-

León's    terms    of   supervised    release   are    to   run   concurrently.

Accordingly, although we otherwise affirm, we return this matter to

the district court for correction of the judgment.

                                III. Conclusion

             Because the jury was entitled to believe the government's

witnesses, there was no error in the court's decision to deny a

judgment of acquittal.         Accordingly, we affirm the judgment, but


      3
      García-León points out that the law-enforcement agents who
testified at trial never saw him at the drug distribution points in
2007 and 2008. This is unremarkable; García-León was incarcerated
then. The cooperating witnesses, on the other hand, testified that
García-León sold drugs when he was free.

García-León's terms of supervised release.   Affirmed and remanded.
