v. No. 24-2156 (D.C. No. 1:21-CR-01501-JCH-1)

RUMALDO PESHLAKAI, (D. N.M.)

Defendant - Appellant.

ORDER AND JUDGMENT*

Before HOLMES, Chief Judge, MORITZ, and ROSSMAN, Circuit Judges.

Rumaldo Peshlakai, a member of the Navajo Nation, pled guilty to violating 18 U.S.C. § 922(g)(1)—the federal felon-in-possession statute. Before entering into a plea agreement, Mr. Peshlakai had filed a motion to suppress. He argued his federal arrest on the charged offense was unlawful because the FBI failed to follow the procedures in the Navajo Nation’s federal detainer statute, Navajo Nation Code Ann. tit. 17, §§ 1962–66 (2017) (the Detainer Statute). The district court rejected that argument and denied the motion,

* This order and judgment is not binding precedent, except under the

doctrines of law of the case, res judicata, and collateral estoppel. It may be cited, however, for its persuasive value consistent with Fed. R. App. P. 32.1 and 10th Cir. R. 32.1.

concluding the Detainer Statute did not apply in Mr. Peshlakai’s circumstances. Mr. Peshlakai now appeals the district court’s order denying his motion to suppress. But he never explains in his opening brief why suppression is available even assuming the Detainer Statute was violated, and he never responds to the government’s contrary argument that suppression is not an appropriate remedy. Exercising jurisdiction under 28 U.S.C. § 1291, we affirm.

A1

The events relevant to this appeal occurred within the Navajo Reservation. Mr. Peshlakai and his wife, C.P., are members of the Navajo Nation.

On September 23, 2021, C.P. called dispatch for the Navajo Police Department (NPD). She reported Mr. Peshlakai assaulted her, took their four children, and fled in a truck with a firearm. The NPD contacted the FBI to assist with the investigation. NPD officers then located Mr. Peshlakai’s truck

1 We take these background facts from the appellate record, including

the district court’s order on Mr. Peshlakai’s motion to suppress. The parties do not dispute these facts unless otherwise noted. See United States v. Hudson, 210 F.3d 1184, 1190 (10th Cir. 2000) (“In reviewing a district court’s ruling on a motion to suppress, this court accepts the district court’s factual findings unless clearly erroneous . . . .”).

in a secluded area, and FBI agents soon joined them. The officers did not find Mr. Peshlakai or his children in the truck.

The officers then set up a “command post” at the NPD’s Window Rock station. RI.160. That evening, Mr. Peshlakai called NPD dispatch and spoke to FBI agents. He said the children were safe with his mother, which the NPD and FBI confirmed. He also agreed to turn himself in the next morning.

On the morning of September 24, Mr. Peshlakai reported to the Window Rock station. Three NPD officers met him outside. One of the NPD officers told Mr. Peshlakai he was under arrest and handcuffed him “in a rough manner.” RI.161; RIII.62; see RIII.63, 65 (Mr. Peshlakai describing the arrest). The officers briefly placed Mr. Peshlakai in an NPD vehicle and then brought him to the NPD booking area, where he took a COVID test. But Mr. Peshlakai was not booked. Instead, the officers brought him to a different part of the station and held him there for thirty to forty-five minutes.

Then FBI agent Curtis Imming arrived. Agent Imming uncuffed Mr. Peshlakai, read him his Miranda rights, and questioned him. Mr. Peshlakai shared information about his domestic issues and firearm possession. Because Mr. Peshlakai had a previous conviction for felony assault, Agent Imming arrested him for possessing a firearm after a felony conviction, in violation of 18 U.S.C. § 922(g)(1).

B

On October 14, 2021, a federal grand jury in the District of New Mexico charged Mr. Peshlakai with violating § 922(g)(1).

On April 29, 2023, Mr. Peshlakai moved to suppress evidence “obtained . . . when FBI Agents . . . conduct[ed] their investigation and arrest.” RI.48. The crux of Mr. Peshlakai’s argument was that his federal arrest violated the Detainer Statute and, therefore, violated the Fourth Amendment. In support, Mr. Peshlakai first contended “the Navajo Nation has a sovereign right not to release tribal defendants to other sovereigns except in accordance with appropriate procedures.” RI.51 (citing, inter alia, Treaty Between the United States of America and the Navajo Tribe of Indians, 15 Stat. 667 (1868)2). And these “appropriate procedures,” Mr. Peshlakai argued, are “set forth in the

2 Mr. Peshlakai was likely referencing this provision of the 1868 Treaty:

If bad men among the Indians shall commit a wrong or depredation upon the person or property of any one, white, black, or Indian, subject to the authority of the United States and at peace therewith, the Navajo tribe agree that they will, on proof made to their agent, and on notice by him, deliver up the wrongdoer to the United States, to be tried and punished according to its laws; and in case they wilfully refuse so to do, the person injured shall be reimbursed for his loss from the annuities or other moneys due or to become due to them under this treaty, or any others that may be made with the United States.

Treaty Between the United States of America and the Navajo Tribe of Indians, 15 Stat. 667, 667 (1868); see United States v. Fox, 573 F.3d 1050, 1054–55 (10th Cir. 2009) (discussing this provision).

[Detainer Statute], 17 N.N.C. §§ 1962-1966.” RI.52. But according to Mr. Peshlakai, the FBI “arrested [him] without following the [Detainer Statute] protocols.” RI.53. For example, he argued, the FBI “failed to submit a federal detainer request,” which the Detainer Statute requires. RI.53; see Navajo Nation Code Ann. tit. 17, § 1963.

To show the FBI’s failure to follow the Detainer Statute constituted a Fourth Amendment violation, Mr. Peshlakai invoked our decision in Ross v. Neff, 905 F.2d 1349 (10th Cir. 1990). In Ross, an Oklahoma police officer arrested an Indian suspect in Indian Country. See id. at 1351–52; see also 18 U.S.C. § 1151 (defining “Indian Country”). We held “an arrest made outside of the arresting officer’s jurisdiction violates the Fourth Amendment.” Ross, 905 F.2d at 1353–54. Relying on the logic of Ross, Mr. Peshlakai contended the FBI “acted without jurisdiction” because it violated the detainer procedures rightfully “enacted by the Navajo Nation.” RI.55. And Mr. Peshlakai reasoned suppression is generally a proper remedy for Fourth Amendment violations, so it was a proper remedy here. RI.54 (citing, inter alia, Walder v. United States, 347 U.S. 62, 64–65 (1954)).

The government opposed the motion to suppress. The Detainer Statute was “inapplicable to Peshlakai’s circumstances,” the government argued. RI.61. The government did not dispute that Agent Imming failed to follow the procedures in the statute. But the government contended “no federal detainer

was required because Peshlakai was never transferred from Navajo Nation custody to federal custody.”3 RI.60. Further, the government maintained the Detainer Statute is implicated only as to “crimes that can [be] prosecuted concurrently under Navajo Nation law and under . . . federal [law].” RI.60 (quoting Navajo Nation Code Ann. tit. 17, § 1962). Because “Peshlakai was subject to arrest . . . under federal law only,” the government argued, “there was no concurrent crime,” so the Detainer Statute was inapposite. RI.61.

The government also challenged Mr. Peshlakai’s reliance on Ross v. Neff.
