v. No. 23-5086 (D.C. No. 4:21-CR-00537-GKF-1) JACOB THOMAS SHELL, (N.D. Okla.)
Defendant-Appellant.
ORDER AND JUDGMENT*
Before HOLMES, SEYMOUR, and BALDOCK, Circuit Judges.
Jacob Shell was charged with, and pled guilty to, one count of Child Abuse in
Indian Country in violation of 18 U.S.C. §§ 1151, 1152, and 13, and Okla. Stat. tit. 21,
§ 843.5(A) (2021). 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”). The district court denied his motion, and Mr. Shell
appeals. Because assimilating the assault provisions of Oklahoma’s child abuse statute
would violate Lewis v. United States, 118 S. Ct. 1135 (1998), we reverse.
* This order and judgment is not binding precedent, except under the doctrines of law of the case, res judicata, and collateral estoppel. While the court generally disfavors the citation of orders and judgments, an order and judgment may be cited under the terms and conditions of 10th Cir. R. 36.3.

I.
The facts of this case are tragic. In February 2020, Mr. Shell violently assaulted
and threw his three-month-old son, H.S.,1 to stop him crying. Mr. Shell’s assault left H.S.
hospitalized for several months and legally blind. As a result of Mr. Shell’s abuse, H.S.
continues to suffer severe physical and mental injuries and developmental delays.
Because H.S. is an Indian and Mr. Shell committed the assault in Indian territory
in Oklahoma, federal prosecutors used the Assimilative Crimes Act (“ACA”) to charge
Mr. Shell in federal court for violating Oklahoma state law. As explained further below,
the ACA allows federal prosecutors to prosecute conduct that would otherwise not be a
federal crime by “borrowing” the laws of the state in which a federal enclave is located.
See generally 18 U.S.C. § 13(a). Prosecutors charged Mr. Shell under the ACA for
violating Oklahoma’s child abuse statute, Okla. Stat. tit. 21, § 843.5(A) (2019) (current
version at Okla. Stat. tit. 21, § 843.5(A)).2
1 To protect the identity of the child, we refer to him as “H.S.” 2 At the time of Mr. Shell’s conduct, Oklahoma’s statute punished “[a]ny parent or other person who [] willfully or maliciously engage[d] in child abuse . . . .” Okla. Stat. tit. 21, § 843.5(A) (2019) (current version at Okla. Stat. tit. 21, § 843.5(A)). The statute defined “child abuse” as the willful or malicious harm or threatened harm or failure to protect from harm or threatened harm to the health, safety or welfare of a child under eighteen (18) years of age by another, or [] the act of willfully or maliciously injuring, torturing or maiming a child under eighteen (18) years of age by another. Id. (emphasis added). Oklahoma’s current child abuse statute moved the definition of “child abuse” to a separate subsection, but is, in nearly all other respects, virtually identical to its predecessor. Compare id., with Okla. Stat. tit. 21, § 843.5(A), (O)(1) (2021). The minor differences between old and new versions have no bearing on our analysis.
2 Appellate Case: 23-5086 Document: 010111081416 Date Filed: 07/18/2024 Page: 3
Mr. Shell moved to dismiss the indictment for failure to state an offense, arguing
that Oklahoma’s child abuse statute could not be assimilated under the ACA and that
prosecutors should have instead charged him under the federal assault statute, 18 U.S.C.
§ 113. He claimed that assimilating Oklahoma’s statute violated the Supreme Court’s
Lewis test by effectively rewriting a federal offense definition and infringing onto a field
Congress intended to wholly occupy, situations in which assimilation is foreclosed. See
Lewis, 118 S. Ct. at 1141. The district court disagreed. It found assimilation of
Oklahoma’s statute was appropriate because the state’s “child abuse statute has no federal
equivalent” and, therefore, the statute “fills a clear and recognized gap in federal law.”
Rec., vol. I at 55. Accordingly, the court denied Mr. Shell’s motion to dismiss. He
ultimately entered a conditional guilty plea and was sentenced to 300 months’
imprisonment with a five-year term of supervised release.
II.
Mr. Shell appeals the district court’s denial of his motion to dismiss, arguing that
Oklahoma’s child abuse statute cannot be assimilated under the ACA. We review de
novo the question of whether a state law is properly assimilated. United States v. Harris,
10 F.4th 1005, 1012 (10th Cir. 2021).
The ACA “provides federal jurisdiction over certain criminal acts committed on”
federal enclaves like military bases, national parks, federal facilities, and Indian

reservations. United States v. Polk, 61 F.4th 1277, 1279 (10th Cir. 2023).3 Often when
criminal acts occur on federal enclaves, they are punishable by federal criminal statutes.
Id. But not always. Sometimes “no particular [federal] statute covers the defendant’s
conduct, meaning that it would not otherwise be a federal crime.” Id. Because gaps in the
federal criminal code remain, see Williams v. United States, 66 S. Ct. 778, 782 (1946),
“the ACA steps in and generates a federal offense using the laws of the state in which the
relevant [enclave] is located.” Polk, 61 F.4th at 1279. Put simply, the ACA “borrows”
state law to fill gaps in the federal criminal law. See Lewis, 118 S. Ct. at 1139. See also
Polk, 61 F.4th at 1279 (“[The ACA] allows federal courts to ‘borrow the relevant crime
from preexisting state law,’ thereby creating an applicable federal offense to fill the gap

The ACA “provides federal jurisdiction over certain criminal acts committed on”

3 In relevant part, the ACA’s statutory language reads:
Whoever within or upon any [federal enclave] is guilty of any act or omission which, although not made punishable by any enactment of Congress, would be punishable if committed or omitted within the jurisdiction of the State, Territory, Possession, or District in which such place is situated, by the laws thereof in force at the time of such act or omission, shall be guilty of a like offense and subject to a like punishment.
18 U.S.C. § 13(a) (emphasis added).
4 Appellate Case: 23-5086 Document: 010111081416 Date Filed: 07/18/2024 Page: 5
The critical question is how to determine whether a “gap” exists in federal law,
such that assimilation under the ACA is appropriate. “By its own terms, the ‘ACA applies
only if the act or omission in question is not made punishable by any enactment of
Congress.’” Harris, 10 F.4th at 1010 (quoting United States v. Rocha, 598 F.3d 1144,
1147–48 (9th Cir. 2010)). “[W]here there is no gap to fill,” state law is not assimilated.
Lewis, 118 S. Ct. at 1141. To determine whether such a gap exists, the Supreme Court
outlined a two-part test in Lewis. First, a court must ask whether “the defendant’s ‘act or
omission . . . [is] made punishable by any enactment of Congress.’” Id. (quoting
18 U.S.C. § 13(a)). If that answer is “no,” then “ACA presumably would assimilate the
statute.” Id.
If the answer is “yes,” we must further ask whether the application of state law is
precluded because: (1) It “would interfere with the achievement of a federal policy”;
(2) “[T]he state law would effectively rewrite an offense definition that Congress
carefully considered”; or (3) “[F]ederal statutes reveal an intent to occupy so much of a
field as would exclude use of the particular state statute at issue.” Id.4 “If any of these
situations apply, then the state statute should not be assimilated, and the charge should be
brought under the federal statute.” Harris, 10 F.4th at 1011. This inquiry’s lodestar “is
one of legislative intent: Does applicable federal law indicate an intent to punish conduct
such as the defendant’s to the exclusion of the particular state statute at issue?” Lewis,
4 We have observed that this list is “non-exhaustive” and that Lewis’s second step “is designed to be a fairly broad inquiry.” Harris, 10 F.4th at 1013.
5 Appellate Case: 23-5086 Document: 010111081416 Date Filed: 07/18/2024 Page: 6
118 S. Ct. at 1142 (emphasis added). The ACA will not apply when both state and federal
statutes “seek to punish approximately the same wrongful behavior,” like, for example,
“where [] differences [between the state and federal crimes] amount only to those of
name, definitional language, or punishment” Id.
A.
Applying the principles in Lewis, we begin by asking whether Mr. Shell’s “‘act[s]
or omission[s] . . . [are] made punishable by any enactment of Congress.’” Id. (quoting
18 U.S.C. § 13(a)). They are.
We look to the indictment to identify the relevant “acts or omissions.” See
Williams, 66 S. Ct. at 780–81. Here, prosecutors charged Mr. Shell for “willfully and
maliciously injur[ing], tortur[ing], and maim[ing] H.S., an Indian child under the age of
18 years . . . by assaulting H.S. . . . with his hands by violently and forcibly throwing and
shaking H.S.’s body.” Rec., vol. I at 110. The government more or less concedes that
such acts are punishable under various provisions of the federal assault statute, 18 U.S.C.
§ 113. Indeed, prosecutors likely could have prosecuted Mr. Shell under at least three
subsections of § 113: § 113(a)(4), which punishes “[a]ssault by striking, beating, or
wounding”; § 113(a)(6), which punishes “[a]ssault resulting in serious bodily injury”;
and, most relevantly, § 113(a)(7), which punishes “[a]ssault resulting in substantial
bodily injury to a spouse or intimate partner, a dating partner, or an individual who has
6 Appellate Case: 23-5086 Document: 010111081416 Date Filed: 07/18/2024 Page: 7
not attained the age of 16 years.” 18 U.S.C. § 113 (emphasis added). Accordingly, we
hold that Lewis’s first step is satisfied.5
B.
We therefore turn to Lewis’s second step and ask whether the federal assault
statute precludes application of Oklahoma’s child abuse statute. Mr. Shell asserts that
assimilating Oklahoma’s statute would both (a) effectively rewrite an offense definition
carefully considered by Congress, and (b) infringe onto a field federal statutes intended to
occupy to the exclusion of state statutes, thereby contravening Lewis’s clear precepts. We
agree and conclude that assimilation of the assaultive provisions of Oklahoma’s child
abuse statute is foreclosed by Lewis’s second step.
We first consider whether assimilating Oklahoma’s statute would “effectively
rewrite an offense definition that Congress carefully considered.” Lewis, 118 S. Ct.
5 We note that, curiously, neither party directly addresses whether Oklahoma’s child abuse statute was divisible. This would seem relevant because Oklahoma’s child abuse statute, then as now, proscribed both abusive acts of commission and abusive acts of omission. See Okla. Stat. tit. 21, § 843.5(A) (2019) (defining “child abuse” as “injuring, torturing or maiming a child” as well as the “failure to protect from harm or threatened harm to the health, safety or welfare of a child”). As Mr. Shell admits, there is no federal law covering abusive acts of omission, like neglectful abuse, emotional abuse, or medical abuse. He thus concedes there is some conduct proscribed by Oklahoma’s statute that is not criminalized by federal law, and he suggests those provisions could be assimilated under the ACA. Reply at 10. These concessions seem to assume, but do not squarely offer, an answer to the question of divisibility. The government similarly acknowledges that Oklahoma’s statute proscribes more conduct than is criminalized by federal law, but never states a clear position on its divisibility. It is not our role to opine on issues not squarely presented, and so we leave the thorny issue of divisibility for another day. See Headrick v. Rockwell Int’l Corp., 24 F.3d 1272 (10th Cir. 1994). Rather, we interpret both parties’ briefs as accepting that the statute is divisible, and we proceed on—but do not adopt—that premise.
7 Appellate Case: 23-5086 Document: 010111081416 Date Filed: 07/18/2024 Page: 8
at 1141. We recently confronted a similar inquiry in United States v. Harris. There, while
camping in Yellowstone National Park, Mr. Harris pointed a gun at another camper amid
a heated argument. Harris, 10 F.4th at 1009. Rather than bringing charges under
18 U.S.C. § 113 (the same federal statute relevant here), prosecutors used the ACA to
assimilate Wyoming’s assault statute, under which they charged and convicted Mr.
Harris. Id. We reversed. We observed that § 113 was comprehensive in the conduct it
criminalized: “The full federal assault statute lays out eight different assaultive acts, each
with a corresponding punishment—from assault with intent to commit murder to simple
assault.” Id. at 1013. Section 113 also provided “specific definitions of terms used in the
statute, including terms such as ‘substantial bodily injury’ and ‘serious bodily injury.’”
Id. at 1013–14. The section’s “detailed and comprehensive nature” convinced us that
assimilating the Wyoming statute “would substantially disrupt Congress’s careful assault
definitions.” Id. at 1014.
All of what we said in Harris about § 113 remains true here. Assimilating the
assault provisions of Oklahoma’s statute would be just as disruptive to “Congress’s
careful assault definitions” in § 113 as assimilating Wyoming’s statute in Harris would
have been. Indeed, we have even more specific concerns in this case. Section 113(a)(7)
punishes “[a]ssualt resulting in substantial bodily injury to . . . an individual who has not
attained the age of 16 years.” 18 U.S.C. § 113(a)(7). Congress’s choices in § 113(a)(7) to
limit one kind of victim to individuals below a fixed age (16); to identify other possible
victims via discrete relationships (“spouses,” “intimate partners,” “a dating partner”); to
insert a detailed, defined term (“substantial bodily injury”); and to set a specific penalty
8 Appellate Case: 23-5086 Document: 010111081416 Date Filed: 07/18/2024 Page: 9
accordingly (“a fine . . . or imprisonment for not more than five years, or both”) all
“indicate an intent to punish conduct such as [Mr. Shell’s] to the exclusion of”
Oklahoma’s statute. Lewis, 118 S. Ct. at 1142. Moreover, as just one example of how
assimilation here would rewrite this federal definition, Oklahoma’s child abuse statute set
its age cutoff at 18—two years beyond the age cutoff in § 113(a)(7) at 16. Okla. Stat.
tit. 21, § 843.5(A) (2019). Such an expansion of a federal offense via state law is
impermissible. See Williams, 66 S. Ct. at 782 (holding that “a conflicting state definition
does not enlarge the scope of the offense defined by Congress”). To assimilate
Oklahoma’s statute, then, would not only generally disrupt the assaultive scheme crafted
by Congress in § 113, but do specific harm to what is, in all but name, the federal
provision aimed at domestic and child assault, § 113(a)(7).
We also defer to Harris’s holding that the “detailed and comprehensive nature of
[§ 113] also suggests Congress” intended to occupy the field of assaultive conduct to the
exclusion of assaultive state provisions, like Oklahoma’s. Harris, 10 F.4th at 1014. We
observed there that (1) the “wide spectrum of assaultive conduct prohibited by § 113” and
(2) the statute’s “broad range of punishments” exhibited specific legislative judgments on
the kinds of assaultive conduct to punish and how severely to punish it. Id. This remains
true here. In Harris, we were loath to undermine the scheme Congress carefully
constructed in § 113 by assimilating Wyoming’s assault statute; we are similarly reticent
here, although there are some distinctions between Harris and this case. The Wyoming
statute in Harris was a “pure” assault statute, see id. at 1012; here, the statute at issue is a
child abuse statute that criminalizes, among other acts, assaultive conduct. See generally
9 Appellate Case: 23-5086 Document: 010111081416 Date Filed: 07/18/2024 Page: 10
Okla. Stat. tit. 21, § 843.5(A) (2019). But Lewis is clear that assimilation is inappropriate
“where both state and federal statutes seek to punish approximately the same wrongful
behavior.” Lewis, 118 S. Ct. at 1142. As noted, the assaultive provisions of Oklahoma’s
child abuse statute and § 113 similarly punish Mr. Shell’s assaultive acts; the differences
we discern “amount only to those of name, definitional language, or punishment,”
differences that do not warrant assimilation. Id. It may be that Mr. Shell’s conduct is
“more easily mapped onto the [Oklahoma] statute,” however, “that is not the test.”
Harris, 10 F.4th at 1014.
Finally, we take seriously in Harris (and in Lewis) the admonition that the “ACA
is only meant to fill gaps in [federal] law, not to provide an additional criminal legal
scheme on every federal enclave.” Id.; see Lewis, 118 S. Ct. at 1141. We are confident
that “the federal assault statute thoroughly covers [Mr. Shell’s alleged] conduct,” Harris,
10 F.4th at 1014, and that there is no federal “gap” for the assaultive provisions of
Oklahoma’s statute to fill. To assimilate here would risk impermissibly “fill[ing]
nonexistent gaps,” which Lewis expressly prohibits. Lewis, 118 S. Ct. at 1141.
III.
Mr. Shell should have been charged under the federal assault statute. He was not,
and assimilation of the assaultive provisions of Oklahoma’s child abuse statute via the
ACA is inappropriate. Accordingly, his motion to dismiss should have been granted. We
reverse.
