ORDER AND JUDGMENT * _________________________________
Before CARSON, KELLY, and ROSSMAN, Circuit Judges. ** _________________________________
When a litigant fails to raise an issue to the district court, we usually deem the
matter forfeited. On appeal, we review forfeited issues under the plain error
standard. For an error to be plain, the error must be “contrary to well-settled law.”
Here, the district court sentenced Defendant Brian Keith Bowen, Jr., to forty-eight
months’ imprisonment after determining that no Sentencing Guideline covered the
offense of conviction. Our jurisdiction arises under 28 U.S.C. § 1291. We conclude
* This order and judgment is not binding precedent, except under the doctrines of law of the case, res judicata, and collateral estoppel.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.
After examining the briefs and appellate record, this panel has determined **
unanimously to honor the parties’ request for a decision on the briefs without oral argument. See Fed. R. App. P. 34(f); 10th Cir. R. 34.1(G). The case is therefore submitted without oral argument. Appellate Case: 25-7011 Document: 57-1 Date Filed: 12/05/2025 Page: 2
that even if the district court erred in making that determination, the error was not
plain. We therefore affirm.

When a mother brought her two-year-old son to an Oklahoma hospital, doctors
discovered a spiral fracture on his right humerus. Medical personnel also identified
bruises on his face and swelling under his scalp. A Cherokee Nation investigation
concluded that the child’s injuries occurred while the mother’s boyfriend, Defendant
Brian Keith Bowen, Jr., cared for the child. Defendant told investigators that the child
fell from a porch.
Federal prosecutors indicted Defendant in the United States District Court for the
Eastern District of Oklahoma for committing child abuse in Indian Country under the
Major Crimes Act, 18 U.S.C. §§ 1151, 1153. The government charged Defendant with
violating Okla. Stat. Ann. tit. 21, § 843.5(A), which criminalizes willful and malicious
harms to children under eighteen by persons who bear caretaking responsibilities.
Defendant pleaded guilty.
At sentencing, the government submitted a memorandum arguing that the
Sentencing Guidelines did not apply because the Sentencing Commission did not
promulgate an analogous provision covering the violation of the Oklahoma statute
under which the government charged Defendant. When no Guideline expressly
covers the offense of conviction, Guideline § 2X5.1 instructs the district court to
sentence defendants without calculating an advisory Guideline range and instead
sentence them directly under 18 U.S.C. § 3553(a). Defendant did not challenge the
2 Appellate Case: 25-7011 Document: 57-1 Date Filed: 12/05/2025 Page: 3
government’s argument that the federal aggravated assault guideline, § 2A2.2, was
not analogous. Probation agreed with the government that no analogous guideline
existed. The presentence report concluded that the court could sentence Defendant to
the maximum allowed by Oklahoma statute, which was life. Defendant did not
object to this but filed a sentencing memorandum asking for a nineteen-month, time-
served sentence. The district court determined the Guidelines did not apply and,
relying on § 3553(a), sentenced Defendant to forty-eight months’ imprisonment.
Defendant appealed.
II.
This appeal presents one question: whether the district court plainly erred in
determining that no Guideline provision is analogous to Defendant’s offense of
conviction. “Typically, the interpretation of a provision of the Sentencing Guidelines
would be a question of law that we would review de novo.” United States v. Garcia-
Caraveo, 586 F.3d 1230, 1232 (10th Cir. 2009) (citing United States v. Zuniga-Soto,
527 F.3d 1110, 1116–17 (10th Cir. 2008)). But because Defendant did not present
this argument to the district court, we review for plain error. Id. (citing United States
v. Juarez-Galvan, 572 F.3d 1156, 1158 (10th Cir. 2009)). Plain error exists when
“(1) error, (2) that is plain, (3) which affects substantial rights, and (4) which
seriously affects the fairness, integrity, or public reputation of judicial proceedings”
is present. Id. (citing United States v. Romero, 491 F.3d 1173, 1178 (10th Cir.
2007)). Defendant argued for this standard of review in his opening brief.

Defendant contends the district court committed plain error in two ways. First,
he asserts the district court ignored the “unambiguous text” of 18 U.S.C. § 113, the
federal assault statute, which contemplates assaulting a child. Second, he posits that
the district court ignored applicable case law.
Looking first at the text of the federal assault statute and Oklahoma’s child

Defendant contends the district court committed plain error in two ways. First,
he asserts the district court ignored the “unambiguous text” of 18 U.S.C. § 113, the
federal assault statute, which contemplates assaulting a child. Second, he posits that
the district court ignored applicable case law.
Looking first at the text of the federal assault statute and Oklahoma’s child
abuse statute, the government takes what Defendant calls the “categorical” approach
set forth in United States v. Clark, 981 F.3d 1154 (10th Cir. 2020). The government
says the Oklahoma statute incorporates three distinct offenses: (1) willfully or
maliciously harming (or threatening to harm) the health, safety, or welfare of a child;
(2) willfully or maliciously failing to protect from harm (or threatened harm) the
health, safety, or welfare of a child; and (3) willfully or maliciously injuring,
torturing, or maiming a child. Defendant rejects a “categorical” approach, instead
focusing on his actual conduct: an assault which caused the child to suffer injuries.
The government points out that the indictment charged Defendant with willfully and
4 Appellate Case: 25-7011 Document: 57-1 Date Filed: 12/05/2025 Page: 5
maliciously injuring the child. And under Oklahoma law, a willful and malicious
injury does not require the use of force. Because the use of force is not required to
commit a violation of the Oklahoma statute, the government contends it is not
comparable to the federal assault statute which requires the use or attempted use of
force. The federal assault statute criminalizes eight distinct forms of assault. The
government did not charge Defendant with committing an assault against a young
child, but rather willfully and maliciously injuring a child. The government argues
this distinction is important because the Oklahoma statute does not require proof a
defendant used force against a child, but only proof that Defendant’s willful conduct
(such as leaving a child unattended on a front porch) led to an injury (such as a fall
from the porch—what Defendant said happened). The government says the federal
assault statute does not cover that. The Oklahoma statute also covers a wide range of
conduct that falls outside the orbit of § 113 such as threatened harms to a child’s
health and the willful failure to protect a child from harm.
As to applicable case law, Defendant relies primarily on our unpublished and
non-precedential decision in United States v. Shell, No. 23-5086, 2024 WL 3455033
(10th Cir. July 18, 2024) (unpublished). In that case, the government charged Shell
with one count of Child Abuse in Indian Country in violation of the same Oklahoma
statute at issue here. Shell, 2024 WL 3455033, at *1. He moved to dismiss the
indictment for failing to state an offense, arguing that Oklahoma’s child abuse statute
should not be assimilated under the Assimilative Crimes Act (“ACA”), 18 U.S.C.
§ 13. Id. The district court denied his motion and Shell appealed. Id. We held that
5 Appellate Case: 25-7011 Document: 57-1 Date Filed: 12/05/2025 Page: 6
assimilating the assault provisions in Shell’s case would violate Lewis v. United
States, 523 U.S. 155 (1998). Id. So we reversed. Id. Lewis held that to determine
whether a gap in federal law exists, we must ask whether any enactment of Congress
punishes the defendant’s act or omission. Id. at *2. If the answer is no, then the
ACA presumably assimilates the statute. Id. If the answer is yes, we must further
ask if the application of state law is precluded because applying it “would interfere
with the achievement of a federal policy. . . .” Id. (quoting Lewis, 523 U.S. at 164).
Stated otherwise, we must determine whether the state law would “effectively rewrite
an offense definition that Congress carefully considered”; or federal statutes “reveal
an intent to occupy so much of a field as would exclude use of the particular state
statute at issue.” Id. (quoting Lewis, 523 U.S. at 164). If any of these situations
apply, then the district court should not assimilate the state statute. Id. The inquiry’s
north star is one of legislative intent—does “federal law indicate an intent to punish
conduct such as the defendant’s to the exclusion of the particular state statute at
issue?” Id. (citing Lewis, 523 U.S. at 166). In Shell, the government indicted Shell
for willfully and maliciously injuring, torturing, or maiming a minor by assaulting
him. Id. at *3. We concluded that the government likely could have prosecuted
Shell under at least three subsections of § 113. Id. So, we concluded that
assimilating the assault provisions of Oklahoma’s statute would disrupt Congress’s
careful assault definitions. Id. at *4. We also opined that the detailed and
comprehensive nature of § 113 suggested Congress’s intent to occupy the field of
assaultive conduct to the exclusion of Oklahoma state law. Id. To assimilate, we
6 Appellate Case: 25-7011 Document: 57-1 Date Filed: 12/05/2025 Page: 7
stated, would risk impermissibly filling nonexistent gaps. Id. at *5. There can be no
doubt that Shell’s framework for determining if a gap exists in federal law is distinct
from the framework here, which evaluates the analogousness of the federal guidelines
to a state crime of conviction. But Defendant argues Shell’s logic should apply here.
In Defendant’s view, if Shell should have been charged under the federal assault
statute, then Defendant should have been sentenced under the corresponding federal
assault guideline.
The question of whether the district court erred in this case is a close one, but
one we need not decide. Instead, in determining whether Defendant is entitled to
relief, we assume the district court erred and decide the question on prong two of our
plain error analysis—whether the error is plain. “An error is plain if it is ‘clear or
obvious at the time of the appeal.’” United States v. Koch, 978 F.3d 719, 726
(10th Cir. 2020) (quoting United States v. Salas, 889 F.3d 681, 686–87 (10th Cir.
2018)). An “obvious” error must be “contrary to well-settled law.” Id. (quoting
Salas, 889 F.3d at 687.) “In general, for an error to be contrary to well-settled law,
either the Supreme Court or this court must have addressed the issue” in a published
decision. Id. (quoting Salas, 889 F.3d at 687). The absence of published decisions
from this court or the Supreme Court, however, does not absolutely preclude a
finding of plain error. Id. (citing Salas, 889 F.3d at 687). But such an absence
generally “will close the door on a claim that the error at issue is clear or obvious.”
United States v. Schneider, 704 F.3d 1287, 1304 (10th Cir. 2013) (Holmes, J.,
concurring joined by Martinez, J., to constitute a majority). And where other circuit
7 Appellate Case: 25-7011 Document: 57-1 Date Filed: 12/05/2025 Page: 8
courts disagree with unpublished dispositions from this circuit, that disagreement
weighs against a finding of plain error. See Koch, 978 F.3d at 726. (citing Salas,
889 F.3d at 687) (stating that the lack of “well settled” circuit precedent and circuit
disagreement on a particular issue both weigh against a finding of plain error).
Here, the Guidelines’ plain text does not directly resolve whether federal
aggravated assault is sufficiently analogous to Oklahoma child abuse. We have no
published Tenth Circuit or Supreme Court case on point. Shell provides some
support for Defendant’s position. But that case lacks precedential value and involves
legal principles distinct from those present in this case. And at least two circuits
have reached the opposite conclusion of Shell regarding the assimilation of state
child abuse statutes. See United States v. Scott, 83 F.4th 796, 800 (9th Cir. 2023)
(concluding Montana’s state law regarding child abuse or neglect was properly
assimilated under the Major Crimes Act because felony child abuse or neglect was
distinct from any of the conduct listed in § 113); United States v. Brown, 608 F.2d
551, 553–54 (5th Cir. 1979) (holding that the government properly proceeded under
the state child abuse statute as made applicable by the ACA); and United States v.
Fesler, 781 F.2d 384, 390–91 (5th Cir. 1986) (“Because Congress has not covered the
precise acts of child abuse covered by Texas state law, the ACA was properly
invoked and applied.”). So, even if we agreed that Shell’s logic controlled the
outcome here, the seeming disagreement among circuit courts with Shell weighs
against finding any error here was clear or obvious at the time of Defendant’s appeal.
