FOR THE FIFTH CIRCUIT

No. 01-40465

Summary Calendar

UNITED STATES OF AMERICA,

Plaintiff-Appellee,

versus

KENNETH LYONS,

Defendant-Appellant.

-------------------- Appeal from the United States District Court

for the Eastern District of Texas

USDC No. 4:00-CR-96-1

-------------------- January 4, 2002

Before DeMOSS, PARKER, and DENNIS, Circuit Judges.

PER CURIAM: *

Kenneth Lyons a ppeals his conviction after a jury trial of

conspiracy to possess with intent to distribute methamphetamine in

violation of 21 U.S.C. §§ 841(a)(1) and 846; possession with intent

to distribute methamphetamine in violation of 21 U.S.C.

§ 841(a)(1); and being a felon in possession of a firearm (enhanced

as an Armed Career Offender) in violation of 18 U.S.C. § 924(e)(1).2

He argues that the district court erred in shifting the burden of

proof to him, instead of the Government, during the suppression

hearing; th at the evidence was sufficient to support his

convictions; that the district court erred in increasing his

offense level for possession of a dangerous weapon; and that the

district court erred in determining the conversion and purity rates

used to calculate the amount of drugs attributable to him under the

Sentencing Guidelines.

In reviewing a ruling on a motion to suppress, this court

reviews the district court's conclusions of law de novo and its

factual findings for clear error. U nited States v. Jordan

, 232

F.3d 447, 448 (5th C ir. 2000). When filing a suppression motion,

the defendant must “first discharge his initial burden of producing

some evidence on specific factual allegations sufficient to make a

prima facie showing of illegality.” U nited States v. De La Fuente

,

548 F.2d 528, 534 (5th Cir. 1977). As Lyons did not satisfy this

initial burden, the district court did not err in placing the

burden of proof on him during the suppression hearing . Even if

Lyons did satisfy this burden, however, and the burden of proof

shifted to the Government to prove the legality of the searches, we

conclude that this burden was satisfied by the Government at the

suppression hearing. S ee United States v. Chavis

, 48 F.3d 871, 872

(5th Cir. 1995).

We review the sufficiency of evidence to determine whether any3

reasonable jury cou ld have found that the evidence established

guilt beyond a reasonable doubt. J ackson v. Virginia

, 443 U.S.

307, 319 (1979); United States v. Martinez

, 975 F.2d 159, 160-61

(5th Cir. 1992). After reviewing the trial transcripts, we are

satisfied that Lyons’ convictions were supported by sufficient

evidence. S ee United States v. Gon zales , 79 F.3d 413, 423 (5th

Cir. 1996); United States v. Cardenas

, 9 F.3d 1139, 1157 (5th Cir.

1993); United States v. DeLeon

, 170 F.3d 494, 496 (5th Cir. 1999);

United States v . Fields , 72 F.3d 1200, 1212 (5th Cir. 1996). We

also conclude that there was no clear error in the district court’s

decision to enhance Lyons’ offense level for possession of a

firea rm under U.S.S.G. § 2D1.1(b)(1). S ee U.S.S.G. § 2D1.1,

comment. (n.3); United States v. Vasquez

, 161 F.3d 909, 912 (5th

Cir. 1998).

Finally, as the district court’s use of a 55% conversion rate

and a 90% purity rate in calculating the drugs attributable to

Lyons under the Sentencing Guidelines was within the ranges stated

b y one or both of the experts who testified at the sentencing

hearing, there was no clear error in this regard. U nited States v.

Torres , 114 F.3d 520, 527 (5th Cir. 1997).

AFFIRMED.
