    UNITED STATES of America, Plaintiff-Appellee, v. Terry Hayes ESTES, Defendant-Appellant.
    No. 03-50998.
    Summary Calendar
    United States Court of Appeals, Fifth Circuit.
    April 21, 2004.
    Joseph H. Gay, Jr, Assistant US Attorney, San Antonio, TX, for Plaintiff-Appellee.
    Raymond L. Kohler, Austin, TX, for Defendant-Appellant.
    Before HIGGINBOTHAM, DAVIS and PRADO, Circuit Judges.
   PER CURIAM.

Terry Hayes Estes pleaded guilty pursuant to a written plea agreement to the manufacture of methamphetamine, and he was sentenced to 235 months’ imprisonment, three years’ supervised release, a $1,000 fíne, and a $100 special assessment.

Estes argues on appeal that he was improperly sentenced because the district court erred in calculating the amount of methamphetamine involved. Estes’s arguments concern the amount of methamphetamine contained in items seized at his home and at the home of Robert Melton. However, the presentence report (“PSR”), which was adopted by the district court, based Estes’s sentence on evidence of Estes’s production of 3.18 kilograms of methamphetamine during the prior seven months, rather than the amount of methamphetamine seized at the two residences. Because Estes has failed to brief the issue whether the use of the 3.18 kilograms in determining his sentence was accurate, the issue is deemed abandoned. See Brinkmann v. Dallas County Deputy Sheriff Abner, 813 F.2d 744, 748 (5th Cir.1987).

Furthermore, to the extent that Estes does argue that he was not responsible for the 3.18 kilograms of methamphetamine attributed to him, the district court did not clearly err in relying on information contained in the PSR because Estes did not meet his burden of proving that the information was “materially untrue, inaccurate or unreliable.” See U.S.S.G. § 1B1.3; United States v. Vital, 68 F.3d 114, 120 (5th Cir.1995); United States v. Rogers, 1 F.3d 341, 344 (5th Cir.1993).

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       Pursuant to 5th Cir. R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5th Cir. R. 47.5.4.
