Summary Calendar

UNITED STATES OF AMERICA,

Plaintiff-Appellee,

versus

MONTE HANHOKYU HAINES,

Defendant-Appellant.

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

for the Southern District of Texas

(L-01-CR-275-1)

-------------------- October 2, 2002

Before DAVIS, WIENER, and EMILIO M. GARZA, Circuit Judges.

PER CURIAM: *

Defendant-Appellant Monte Hanhokyu Haines appeals the district

court’s denial of his motion to suppress the marijuana discovered

in his vehicle by border patrol agents at the Agua Nueva permanent

checkpoint. He argues that (1) the agents lacked reasonable

suspicion to detain him beyond the time necessary to check his

immigration status, and (2) he did not voluntarily consent to the

search of his tractor-trailer, the vehicle in which the agents

discovered the marijuana.2

On appeal from the denial of a motion to suppress, we review

the district court’s factual findings for clear error, and we

r eview de novo the court’s legal conclusions, such as whet her

reasonable suspicion existed. U nited States v. Inocencio

, 40 F.3d

716, 721 (5th Cir. 1994). Further, “[t]he evidence presented at a

pre-trial hearing on a motion to suppress is viewed in the light

most favorable to the prevailing party.” I d. We consider the

totality of the circumstances in determining whether reaso nable

suspicion existed at the time of the detention or search. United

States v. Smith , 273 F.3d 629, 634 (5th Cir. 2001).

The district court identified several factors that support the

agents’ contention that they had a reasonable suspicion of criminal

activity. Even if, as Haines asserts, each factor, taken alone,

could be consistent with innocent behavior, the relevant inquiry is

whether the “totality of the circumstances” created a reasonable

suspicion of criminal activity. S ee Smith

, 273 F.3d at 634-35.

Viewed in the light most favorable to the government, as the

prevailin g party, the totality of the circumstances supports the

district court’s conclusion that the agents had a reasonable

suspicion of criminal activity, justifying their continued

detenti on of Haines. S ee id. The district court did not err in

denying Haines’ motion to suppress on this basis.

We review the question whether Haines voluntarily and clearly

consented to the search of his vehicle under the clearly erroneous

standard, which “is particularly strong since the [district court]3

had the opportunity to observe the demeanor of the witnesses” at

the suppression hearing. United States v. Gonzales , 79 F.3d 413,

421 (5th Cir. 1996)(internal quotation marks and citations

omitted). Although Haines was not in the custody of the agents and

the agents did not inform Haines of his right to deny consent, (1)

they did not use any coercive measu res to obtain his consent to

search the trailer; (2) he appeared cooperative; and (3) he was an

experienced t ruck driver who had been through checkpoints

innumerable times. S ee United States v. Olivier-Becerril

, 861 F.2d

424, 426 (5th Cir. 1988). Furthermore, when viewed in the light

most favorable to the government, the testimony of the agents and

Haines suppor ts the district court’s finding that Haines

voluntarily and clearly consented. The district court did not err

in denying Haines’s motion to suppress based on the finding of

clear and voluntary consent.

As Haines concedes, his challenge to the constitutionality of

permanent checkpoints is foreclosed by United States v. MartinezFuerte

, 428 U.S. 543 (1976), which we are bound to follow. S ee

United States v. Dabeit , 231 F.3d 979, 984 (5th Cir. 2000), cert.

denied , 531 U.S. 1202 (2001).

The district court’s judgment is, in all respects,

AFFIRMED.
