U.S. COURT OF APPEALS

FOR THE NINTH CIRCUIT

UNITED STATES OF AMERICA, No. 24-910 D.C. No. Plaintiff - Appellee, 4:23-cr-00941-SHR-LCK-1 v.

MEMORANDUM*

ZACKERY ALLEN MCKENZIE,

Defendant - Appellant.

Appeal from the United States District Court for the District of Arizona Scott H. Rash, District Judge, Presiding

Submitted April 2, 2025** Phoenix, Arizona

Before: HAWKINS, W. FLETCHER, and R. NELSON, Circuit Judges.

Appellant Zackery McKenzie (“McKenzie”) appeals his bench trial

conviction for one count of Conspiracy to Transport Illegal Aliens for Profit and

three counts of Transportation of Illegal Aliens for Profit in violation of 8 U.S.C.

* This disposition is not appropriate for publication and is not precedent except as provided by Ninth Circuit Rule 36-3. ** The panel unanimously concludes this case is suitable for decision without oral argument. See Fed. R. App. P. 34(a)(2). § 1324(a)(1), challenging the denial of his motion to suppress evidence obtained

from a traffic stop in a national wildlife refuge north of the Arizona–Mexico border.

We affirm.

We review de novo the denial of a motion to suppress and the determination

of underlying factual findings for clear error. United States v. Lara, 815 F.3d 605,

608–09 (9th Cir. 2016) (citing United States v. Mayer, 560 F.3d 948, 956 (9th

Cir. 2009)). We also review de novo a district court’s interpretation of a federal

regulation. See United States v. Obendorf, 894 F.3d 1094, 1098 (9th Cir. 2018).

McKenzie was not exempt from 50 C.F.R. § 27.31 simply because he was

traveling on Arizona State Route 286. State traffic laws “shall govern traffic” in

national wildlife refuges. Id. § 27.31(a). Further, Fish and Wildlife Officers are

authorized to “insure the safety of the using public to the fullest degree possible” in

these refuges. 50 C.F.R. § 28.21. Together, these regulations expressly contemplate

Fish and Wildlife Officers conducting traffic stops on roads within refuges.

McKenzie failed to demonstrate that state-owned highways within a refuge

fall outside of § 27.31(a)’s ambit. To read an unstated exception for state-owned

highways would conflict with the duties of Fish and Wildlife Officers. See Barboza

v. Cal. Ass’n of Pro. Firefighters, 651 F.3d 1073, 1078 (9th Cir. 2011) (“Under our

precedent, we construe regulations so as to give effect and meaning to each of a

regulation’s subsections, if possible.”); 50 C.F.R. § 28.21. Therefore, by traveling

2 24-910 10 miles per hour over the posted speed limit in violation of A.R.S. § 28-702.01,

McKenzie violated 50 C.F.R. § 27.31(a), and Officer Amos acted within his

authority in conducting the stop.

McKenzie’s Tenth Amendment argument also fails as Congress delegated its

authority to the Secretary of the Interior to regulate national wildlife refuges. See

United States v. Millis, 621 F.3d 914, 917 (9th Cir. 2010). Given that Congress

exercised its authority over that federal land, “the Tenth Amendment expressly

disclaims any reservation of that power to the States.” New York v. United States,

505 U.S. 144, 156 (1992).

Officer Amos’s actions were permissible under the Fourth Amendment. See

United States v. Becerra-Garcia, 397 F.3d 1167, 1175 (9th Cir. 2005) (rejecting that

a traffic stop “is automatically unreasonable if the officers lacked authority to

conduct the seizure”). Confirming through his radar system that McKenzie was

traveling 10 miles per hour over the posted speed limit, Officer Amos reasonably

believed this to be a violation of federal regulations. This was sufficient justification

to conduct the traffic stop. See United States v. Choudhry, 461 F.3d 1097, 1100 (9th

Cir. 2006) (“A traffic violation alone is sufficient to establish reasonable

suspicion.”). During the stop, the undocumented immigrants were in plain view as

Officer Amos approached the vehicle.

3 24-910 Observing five people wearing camouflage “piled on top of each other in the

back seat” not previously visible in the vehicle, coupled with Agent Weber’s

previous observations, provided a constitutionally sufficient reason to investigate

further. See United States v. Evans, 786 F.3d 779, 788 (9th Cir. 2015) (“[A]n officer

may prolong a traffic stop if the prolongation itself is supported by independent

reasonable suspicion.”); see also United States v. Diaz-Castaneda, 494 F.3d 1146,

1152–53 (9th Cir. 2007) (allowing police to ask for identification at a traffic stop).

No Fourth Amendment violation occurred here.

AFFIRMED.
