Appellate Case: 24-8073 Document: 21-1 Date Filed: 10/20/2025 Page: 1 FILED United States Court of Appeals Tenth Circuit UNITED STATES COURT OF APPEALS October 20, 2025 FOR THE TENTH CIRCUIT _________________________________ Christopher M. Wolpert Clerk of Court UNITED STATES OF AMERICA,

v. No. 24-8073 (D.C. Nos. 1:08-CV-00097-SWS RAYMOND DEAN BROWN, & 2:00-CR-00059-SWS-1) (D. Wyo.) Defendant - Appellant. _________________________________

ORDER DENYING CERTIFICATE OF APPEALABILITY * _________________________________

Before HARTZ, MORITZ, and ROSSMAN, Circuit Judges. _________________________________

Raymond Dean Brown, a federal prisoner proceeding pro se, seeks a certificate of

appealability (COA) to challenge the district court’s denial of a motion he filed under

Fed. R. Civ. P. 60(b) in his proceedings under 28 U.S.C. § 2255. We deny Brown’s

request for a COA and dismiss this matter.

I. Background

Brown was arrested in a Wyoming parking lot in 1999. A vehicle search

uncovered a machine gun, and a search of his residence uncovered a methamphetamine

manufacturing operation. While state drug and firearm charges were pending against

* This order is not binding precedent except under the doctrines of law of the case, res judicata, and collateral estoppel.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. Appellate Case: 24-8073 Document: 21-1 Date Filed: 10/20/2025 Page: 2

him, Brown and his attorney met with a state prosecutor to determine if the state would

offer him a deal in exchange for information. Also attending this “proffer meeting” was

Dennis Claman, a deputy sheriff with the Sweetwater County Sheriff’s Office assigned as

a task force special agent with the Wyoming Division of Criminal Investigation. Brown

and his attorney had requested the proffer meeting to share information about an alleged

murder. According to testimony Claman provided at Brown’s federal trial, the state

prosecutor informed Brown that although any information he provided at the meeting

“would not be used against him in state court, the state could not bind federal

authorities.” United States v. Brown (Brown I), 400 F.3d 1242, 1246 (10th Cir. 2005).

“Brown expressly acknowledged that he understood these terms.” Id. at 1255–56.

According to Claman, Brown said he knew the identity and address of the man “who

made that gun” and had “‘converted [Brown’s] gun to full auto[matic] in Illinois.’”

R. vol. 2 at 36–37 (district court order denying § 2255 relief, quoting Trial Tr. vol. 3

at 437–38). Brown’s attorney then advised him not to say anything else about the gun.

Claman later informed federal agents about Brown’s knowledge of the altered gun and its

fabricator.

Brown pleaded nolo contendere to two state drug charges, and the state dismissed

two other charges. A week later, a federal grand jury indicted Brown on three charges:

felon in possession of a firearm, unlawful possession of a machine gun, and carrying a

machine gun during and in relation to a drug trafficking crime. The federal prosecutor

designated Claman as the case agent in the federal case. Brown filed a pretrial motion to

suppress the statements he made at the proffer meeting. The district court reserved ruling

on the motion. Brown did not renew the motion at trial, and the government presented

his proffer-meeting statements through Claman’s testimony without objection.

A jury convicted Brown on all three charges. We affirmed his convictions but

remanded for resentencing. On remand, the district court sentenced Brown to 30 years’

imprisonment on the conviction for carrying a machine gun during and in relation to a

drug-trafficking crime, to be served consecutively to the 30-month sentence on the other

counts. See United States v. Brown (Brown II), 212 F. App’x 747, 750–51 (10th Cir.

2007). We affirmed. See id. at 756.

In 2008 Brown sought relief from his convictions by filing a pro se 28 U.S.C.

§ 2255 motion. He raised numerous claims, including three claims of ineffective

assistance of trial counsel related to the information he provided at the proffer meeting.

The district court denied the § 2255 motion. On appeal we remanded for further

proceedings on the three ineffective-assistance claims. See United States v. Brown

(Brown III), 640 F. App’x 752, 756 (10th Cir. 2016).

On remand the district court appointed counsel for Brown, ordered supplemental

briefing, held an evidentiary hearing, and accepted additional briefing after the hearing.

In 2021 the district court denied all three ineffective-assistance claims. We denied

Brown a COA to appeal from that ruling. See United States v. Brown (Brown IV),

No. 21-8083, 2022 WL 4103071, at *3 (10th Cir. Sept. 8, 2022).

Brown then filed a motion, through counsel, under Fed. R. Civ. P. 60(b). Brown

argued that the district court had never ruled on a claim he presented in ground two of his

§ 2255 motion—that when the prosecutor introduced Claman’s testimony at Brown’s

3 Appellate Case: 24-8073 Document: 21-1 Date Filed: 10/20/2025 Page: 4

federal trial, the United States breached his state plea agreement. Brown contended that

it was “undisputed” that at the proffer meeting, “Claman was working with both the State

of Wyoming and the federal government.” Suppl. R. at 51. Brown asserted that “federal

prosecutors deliberately chose him as the lead case agent for the federal prosecution, fully

aware of his close involvement with the State of Wyoming, including [at] the proffer

meeting,” id., and this made Claman “an arm of the federal prosecution,” id. at 52.

Brown concluded that Claman breached the plea agreement when he testified about

Brown’s statements at the proffer meeting, and Claman’s breach was “legally equivalent

to” the federal prosecutor’s breaching the agreement and violating the prohibition of Fed.

R. Evid. 410(a) against the use of statements made by a defendant during plea discussions

resulting in a nolo contendere plea. Id. at 54. Brown asked the court to reopen his

§ 2255 proceeding as to ground two and set aside his conviction.

The district court treated the motion as a true Rule 60(b)(4) motion based on a

void judgment and denied it. 1 The court first determined that it would not be error to

decline to rule on Brown’s breach claim because it was not among the

ineffective-assistance claims included in the Brown III remand. But the court then
