IN THE UNITED STATES DISTRICT COURT
FOR THE NORTHERN DISTRICT OF IOWA
WESTERN DIVISION
UNITED STATES OF AMERICA,
Plaintiff, 	No. 25-CR-4055-LTS-KEM
vs. 	ORDER
MANUEL NEGRETE-VACA,
Defendant.
____________________
Defendant Manuel Negrete-Vaca moves to dismiss the indictment charging him
with failing to register as a sex offender under the Sex Offender Registration and
Notification Act (SORNA), 18 U.S.C. §§ 2250(a), (b). Doc. 23. Resolution of Negrete-
Vaca’s motion requires determining whether his prior Iowa conviction of assault with
intent 	to 	commit 	sexual 	abuse 	constitutes 	a 	“sex 	offense” 	requiring 	registration.
Defendant argues that to be a sex offense under SORNA, the crime must have a sexual-
gratification element and that assault with intent to commit sexual abuse lacks that
element. I agree and recommend granting the motion to dismiss.
I. 	BACKGROUND
On June 23, 2020, Negrete-Vaca was convicted of assault with intent to commit
sexual abuse, in violation of Iowa Code § 709.11(3), in the Iowa District Court for Sac
County.1 Doc. 23-2. 	The victim was an adult. 	See Doc. 23-4. 	The indictment in this
case charges Negrete-Vaca with failing to register as a sex offender in violation of
1 The Iowa District Court’s Record of Plea of Guilty and Sentencing Order required Defendant
to register as a sex offender with the state of Iowa pursuant to Iowa Code Chapter 692A. Doc.

SORNA from April 1, 2022, to August 5, 2024. 	Doc. 17. 	The indictment alleges that
he was required to register because of his prior Iowa conviction. 	Id.
Defendant moved to dismiss the indictment, arguing that his Iowa conviction does
not require SORNA registration. 	Doc. 23. 	The Government filed a resistance (Doc.
28), and Defendant filed a reply (Doc. 29). The parties then filed supplemental briefing
at my request. 	Docs. 30, 33, 34. 	The parties’ arguments hinge on whether the federal
SORNA statute and the Iowa assault with intent to commit sexual abuse statute both
require a particular element, which is an issue of statutory interpretation and thus a legal
question. Accordingly, this court can resolve the issue on a motion to dismiss.2
II. 	DISCUSSION
Defendant Manuel Negrete-Vaca’s motion to dismiss the indictment in this case
requires the court to determine whether assault with intent to commit sexual abuse under
Iowa law constitutes a “sex offense” requiring registration as a sex offender under
SORNA. Defendant argues that to be a sex offense under SORNA, the crime must have
a sexual-gratification element and that Iowa’s assault with intent to commit sexual abuse
lacks that element. 	The Government asserts that “Iowa’s definition of ‘sex abuse’
requires a ‘sex act.’ SORNA registration requires an ‘element involving a sex act. . . .
Therefore, defendant’s sex abuse contains an ‘element involving a sex act,’ and defendant
is a ‘sex offender’ under SORNA.” Doc. 28 at 2. However, this simplification ignores
the potential for different definitions of a “sex act” under Iowa law and a “sex act” under
SORNA.

A. 	Sexual Offense Under SORNA
SORNA requires registration by a “sex offender.”3 “Sex offender” is defined as
a person “convicted of a sex offense.”4 The definition of “sex offense” includes “a
criminal offense that has an element involving a sexual act or sexual contact with
another.”5
When 	a 	statute 	requires 	comparing 	a 	defendant’s 	prior 	conviction 	to 	other
offenses, “[f]ederal courts generally use one of two analytical approaches.”6 Under the
categorical approach, the court ignores the defendant’s actual conduct and compares the
elements of a prior offense with the elements of the federal statute.7 If the underlying
offense extends more broadly, punishing more conduct than the federal definition, then
the conviction does not qualify as a predicate offense.8 Under the circumstance-specific
approach, on the other hand, the court considers the “particular circumstances in which
an offender committed the crime on a particular occasion.”9 Because the SORNA
provision defining a sex offense as “a criminal offense that has an element involving a
sexual act or sexual contact with another” requires looking at the “element[s]” of the
offense, the categorical approach applies, and the court does not consider the underlying

offense conduct.10 As such, the underlying conviction will only qualify as a sex offense
under SORNA if the “statute under which he was convicted covers the same conduct as
– or a narrower range of conduct than – SORNA.”11 Both parties appear to agree about
the application of the categorical approach to determine whether an underlying offense
requires registration under SORNA.
SORNA does not define “sexual act” or “sexual contact.” 	When a statute leaves
a term undefined, the court applies its “ordinary, contemporary, common meaning.”12
Relying on dictionary definitions of the word “sexual,” circuit courts have defined a
“sexual act” or “sexual contact” in SORNA as acts or contacts “related to or for the
purpose of sexual gratification.”13 A district court in this circuit has agreed.14 In Barker
v. United States, the Western District of Missouri defined sexual contact and sexual act
consistent with their ordinary meaning to require a sexual gratification component, and

that a Florida conviction for attempted sexual battery does not qualify as a sex offense
under SORNA because it is not so limited.15 The court noted that in a sentencing context
“the Eighth Circuit has held the plain and ordinary meaning of the term ‘sexual’
necessarily 	includes 	that 	an 	‘intent 	in 	committing 	the 	[act] 	is 	to 	seek 	libidinal
gratification.’”16
Some district courts have looked to the definition of sexual act and sexual contact
in 18 U.S.C. § 2246.17 That statute, entitled “Definitions for chapter,” defines terms
“[a]s used in this chapter,”18 Chapter 109A, which sets out the federal offenses of
aggravated sexual abuse, sexual abuse, sexual abuse of a minor or ward, and abusive

(D.S.D. July 16, 2025). Section 2246 defines “sexual act” as follows:
(A) contact between the penis and the vulva or the penis and the anus, and for
purposes of this subparagraph contact involving the penis occurs upon penetration,
however slight;
(B) contact between the mouth and the penis, the mouth and the vulva, or the
mouth and the anus;
(C) the penetration, however slight, of the anal or genital opening of another by
a hand or finger or by any object, with an intent to abuse, humiliate, harass,
degrade, or arouse or gratify the sexual desire of any person; or
(D) the intentional touching, not through the clothing, of the genitalia of another
person who has not attained the age of 16 years with an intent to abuse, humiliate,
harass, degrade, or arouse or gratify the sexual desire of any person.
18 U.S.C. § 2246(2). It defines “sexual contact” as “the intentional touching, either directly or
through the clothing, of the genitalia, anus, groin, breast, inner thigh, or buttocks of any person
with an intent to abuse, humiliate, harass, degrade, or arouse or gratify the sexual desire of any
person.” 18 U.S.C. § 2246(3).

sexual contact.19 Because SORNA is not in Chapter 109A and importing a definition
from § 2246 into SORNA conflicts with the language and structure of the statutes, circuit
courts have uniformly rejected importing these definitions to SORNA.20 Similarly, the
Eighth Circuit has declined to import the Chapter 109A definitions of “sexual act” and
“sexual contact” to a different chapter when analyzing a sentencing enhancement.21
Thus, I reject the importation of a definition from Chapter 109A into SORNA.
Consistent with the Western District of Missouri, I find the Fourth and Eleventh
Circuit’s analysis compelling and construe “sexual act” and “sexual contact” according
to their ordinary meaning, which requires a purpose of sexual gratification. 	The
Government does not identify authority holding that SORNA does not require an element
sexual gratification to constitute a sexual act or sexual contact.
19 The Government does not expressly offer a definition of “sexual act” or “sexual contact”
under SORNA but it does equate Iowa’s law and federal definitions, stating they “substantially
track” and cites 18 U.S.C. § 2246(2), (3) and Iowa Code §§ 702.17, 709.1. See Doc. 28 at 8.
20 Vineyard, 945 F.3d at 1173 (stating that the “argument that the definition of sexual contact
used in 18 U.S.C. § 2246 should be imported into SORNA conflicts with the language and
structure of both statutes” and “there is no legislative relationship between SORNA and [Section]
2246”); Helton, 944 F.3d at 207 (finding there was “no indication that Congress intended to
import the definitions of chapter 109A to [another] chapter” and noting that Section 2246
“explicitly limits the definitions provided therein to the chapter in which it resides” because the
wording and title of that section limits it to that chapter (“[a]s used in this chapter” and
“[d]efinitions for chapter.”) (quoting United States v. Fugit, 703 F.3d 248, 255-56 (4th Cir.
2012)); Westerman, 705 F. App’x at 652 (“We are not persuaded that Congress intended ‘to
import the elements of offenses delineated elsewhere in the U.S. Code,’ and therefore decline to
import the definitions of ‘sexual act’ and ‘sexual contact’ found in 18 U.S.C. § 2246(2), (3).”).
21 See Sonnenberg, 556 F.3d at 670-71 (rejecting the argument that definitions of federal offenses
from Chapter 109A should apply to a sentencing enhancement applicable if a prior state
conviction was “under the laws of any State relating to aggravated sexual abuse, sexual abuse,
or abusive sexual conduct involving a minor or ward,” noting that “the statute does not instruct
us to apply chapter 109A’s definitions”; the court defined “sexual” for “sexual abuse” under its
ordinary meaning as needing intent to seek libidinal gratification, and concluded that a prior
conviction for committing lascivious act with children triggered the enhancement.).

B. 	Iowa Assault with Intent to Commit Sexual Abuse
As previously noted, Defendant was convicted of violating Iowa Code § 709.11(3),
which reads, “[a]ny person who commits an assault, as defined in section 708.1, with the
intent to commit sexual abuse ... [i]s guilty of an aggravated misdemeanor if no injury
results.” Assault with the intent to commit sexual abuse under Iowa law in 2020 required
proof of an assault—which includes things like physical acts of violence or displaying a
dangerous weapon in a threatening manner—“with the intent to commit sexual abuse.”22
Sexual abuse, in turn, is “[a]ny sex act . . . when the act is performed with the other
person” when “[t]he act is done by force or against the will of the other,” with a person
incapable of giving consent due to a “mental defect or incapacity,” or with a child.23 It
is thus “a nonconsensual sex act.”24 Intending to commit sexual abuse requires proof of
“the intent to commit a sex act . . . by force or against the will of the victim.”25 In 2020,
the Iowa Code defined “sex act” to mean:
[A]ny sexual contact between two or more persons by any of the following:
1. Penetration of the penis into the vagina or anus.
2. Contact between the mouth and genitalia or by contact between
the genitalia of one person and the genitalia or anus of another
person.
3. Contact between the finger or hand of one person and the genitalia
or anus of another person . . . .
4. Ejaculation onto the person of another.
22 Iowa Code § 709.11 (2020) (assault with intent to commit sexual abuse); Iowa Code § 708.1
(assault). 	The Iowa Supreme Court has interpreted this statute to mean: “(1) the defendant
assaulted the alleged victim, (2) with the intent to commit a sex act, (3) by force or against the
will of the victim.” State v. Beets, 528 N.W.2d 521, 523 (Iowa 1995).

5. By use of artificial sexual organs or substitutes therefor in contact
with the genitalia or anus.26
Thus, “a ‘sex act’ requires some touching of the anus or genitalia” (although it may be
through clothes).27
Not all contact “between the specified body parts (or substitutes)” qualifies as a
“sex act” for purposes of sexual abuse—the contact “must be sexual in nature.”28 “The
sexual nature of the contact can be determined from the type of contact and the
circumstances surrounding it.”29 In State v. Pearson, the Iowa Supreme Court stated:
[T]he contact between an adult and a child bouncing on his or her lap would
not be sexual in nature unless the circumstances surrounding it suggested it
was. 	Such circumstances certainly include whether the contact was made
to arouse or satisfy the sexual desires of the defendant or the victim.
However, the lack of such motivation would not preclude a finding of sexual
abuse where the context in which the contact occurred showed the sexual
nature of the contact. 	Other relevant circumstances include but are not
limited to the relationship between the defendant and the victim; whether
anyone else was present; the length of the contact; the purposefulness of the
contact; whether there was a legitimate, nonsexual purpose for the contact;
where and when the contact took place; and the conduct of the defendant
and victim before and after the contact.30

27 In re A.G., 2003 WL 289261, at *1.
28 State v. Pearson, 514 N.W.2d 452, 455 (Iowa 1994). In State v. Monk, the court held a jury
could find sufficient evidence of sexual abuse when the defendants and victim were teenagers
who were “good friends” and frequently engaged in “teasing, wrestling, and similar horseplay,”
and during a party, defendants stuck a broom handle into the victim’s anus, after which
“[e]veryone laughed before [the victim] pushed the broom away and ran to the bathroom crying.”
The court recognized, however, that “the jury could have concluded the incident was not sexual
in nature” and found error in the jury instruction defining a “sex act” based on “contact” between
body parts, rather than specifically requiring “sexual contact.” 514 N.W.2d 448, 450-52 (Iowa
1994).

Thus, the Court has held that sexual abuse requires a contact that is “sexual in nature,”
but not necessarily for the purpose of sexual gratification. 	Other circumstances can
demonstrate that the contact is sexual in nature.
Twenty-seven years later the Iowa Supreme Court declined to overrule Pearson
and rejected the defendant’s argument that sexual abuse required proof he sought sexual
gratification.31 In State v. Montgomery, the court stated “[t]he legislature codified a
sexual gratification element for lascivious acts but not for sexual abuse, which can be
proven by sexual contact without a motive of sexual gratification.”32 Pointing to
lascivious acts with a child, indecent contact with a child, lascivious conduct with a
minor, and sexual exploitation by a counselor or therapist, the court stated that “[t]he
legislature knows how to require that conduct be done” for sexual gratification “because
it has codified that element in other criminal statutes.”33 The court “reaffirm[ed] Pearson
and again decline[d] to engraft an additional element the legislature omitted.”34 Relying
in part on the doctrine of legislative acquiescence, the court presumed that the legislature
has acquiesced in the court’s interpretation because so many years passed following
Pearson.35 Because “[t]here are valid policy reasons why the legislature might want to
criminalize sexual abuse that is not for the purpose of sexual gratification,” conduct may
be sexual in nature and thus a sex act when “performed to exert power or control over
31 State v. Montgomery, 966 N.W.2d 641, 645-46 (Iowa 2021).
32 Id., at 646. 	Iowa Code § 709.8 (lascivious acts with a child) makes unlawful specified acts
with a child “for the purpose of arousing or satisfying the sexual desires of either of them.”
33 Id., at 651. Other sections of the Iowa Code also specify that a crime be “sexually motived”
(defined as “one of the purposes for commission of a crime is the purpose of sexual gratification
of the perpetrator of the crime”), such as Iowa sex offender registration (Iowa Code §
692A.126), civil commitment (Iowa Code § 229A.2), harassment (Iowa Code § 708.15 requires
registration if against a minor and sexually motivated).

the victim without a motivation of sexual gratification.”36 As such, under Iowa law the
act required for sexual abuse need not be made to arouse or satisfy the sexual desires of
the defendant or the victim.
Addressing Montgomery and Pearson, the Government does not contest that Iowa
courts declined to add an element of sexual gratification but states that “a sexual nature
is still required to be proven to secure a conviction for any sex act or sex abuse” and that
“[n]o matter the gratification, the contact must still be sexual.” 	Doc. 28 at 5. 	The
Government does not state clearly whether sexual gratification is required but rather
asserts “even with the narrower statutory language here, assault with intent to commit
sexual abuse qualifies as a sex offense.” This conclusion fails to address how, under the
categorical approach, sexual abuse that does not have an element of sexual gratification
can constitute a sexual offense that does include an element of sexual gratification.
Both parties rely on United States v. Carrillo-Topete, which is a non-SORNA case
that held that a prior Iowa conviction for assault with intent to commit sexual abuse
“related 	to” 	sexual 	abuse 	and 	thus 	triggered 	a 	mandatory 	minimum 	sentence 	for
possessing child pornography.37 The Eighth Circuit compared the definition of “sexual
abuse” in the federal statute and under Iowa law and noted: “we have held that the two
definitions are close enough” because “‘sex acts’ by force or against the will of someone
else necessarily involve ‘physical . . . misuse or maltreatment, meaning ‘the full range
of conduct’ covered by the Iowa statute ‘fits squarely within’ the generic federal
36 Id. (favorably citing State v. Davis, 584 N.W.2d 913, 917 (Iowa Ct. App. 1998), in which
the defendant suffocated his girlfriend with a pillow after she declined his request for sex, then
beat her and put his fist inside her vagina, causing lacerations; the court rejected defendant’s
argument that he desired to hurt his girlfriend by putting his fist in her vagina and that the act
was therefore not sexual in nature, noting they were lovers, he asked for sex an hour before the
contact, and her refusal prompted his violent behavior).

definition.”38 The Government relies heavily on that statement, but in characterizing
them as “close enough” and using the term “fits squarely within” the court was looking
at the conduct itself, not any motivation for that conduct. Moreover, as Defendant points
out, 	the 	court 	noted 	the 	“potential 	mismatch 	between 	the 	reference 	to 	‘sexual
gratification’ in the federal definition, and the absence of a sexual-purpose requirement
in Iowa,” concluding that the defendant waived that argument.39 Significantly, in that
case eligibility did not require a statutory match-up of elements, but instead one offense
must simply relate the other. 	As the Government acknowledges, this is an “admittedly
broader” standard. Doc. 28 at 6.
The remaining consideration is whether assault to commit sexual abuse differs
from sexual abuse by requiring a purpose of sexual gratification. 	While sexual abuse
requires general intent, assault with intent to commit sexual abuse requires specific
intent.40 Iowa courts have stated that the standard for determining whether a defendant
had the specific intent to commit sexual abuse is:
The overt act must reach far enough towards the accomplishment, toward
the desired result, to amount to the commencement of the consummation,
not merely preparatory. It need not be the last proximate act to the
consummation of the offense attempted to be perpetrated, but it must
approach sufficiently near it to stand either as the first or some subsequent
step in a direct movement towards the commission of the offense after the
preparations are made.41
Recently, the court clarified that a defendant’s “overt act toward committing sexual abuse
describes only one powerful form of circumstantial evidence from which specific intent

can be inferred” but that specific intent is “to achieve a sex act specifically described in
section 	702.17,” 	without 	mentioning 	any 	purpose 	of 	gratification.42 In 	addition,
“[e]vidence sufficient to prove necessary specific intent includes sexual comment,
touching in a sexual manner, attempt to remove clothing, or an act in any other way
which would indicate a plan to engage in sexual activity.”43 The purpose then is to
commit the defined sex act, not to achieve sexual gratification. 	For example, the Iowa
Supreme Court has noted that the act of a defendant placing a hand on a girl’s breast
“was an assault and may have involved a sex oriented purpose” but “this act alone was
not sufficient” because “the purpose of this conduct might well have been limited to
fondling of the girl’s breast” and not to engage in a sex act as defined in § 702.17.44 In
State v. Beets, the Iowa Supreme Court upheld a conviction for assault with intent to
commit sexual abuse because the trial court found that the defendant “committed an
assault upon the victim by grabbing and fondling her body against her will” and “intended
to commit a sex act of penis to vagina contact or contact between his penis and the hand
of [the victim].”45 The court concluded there was substantial evidence to support the
conviction, without ever addressing any motivation for the defendant’s acts.46 As such,
Iowa courts may require some sort of plan or overt act to achieve a sex act for specific

He is much larger than she. He lunged at her, grabbing and fondling her. She protested and
struggled against the assault. Beets attempted to make contact between his penis and her hand or
her vagina. This evidence sufficiently supports the conviction of assault with intent to commit
sexual abuse.”).

intent, but I have not found any Iowa authority limiting that plan or overt act to those
with the purpose of sexual gratification. 	Indeed, there is no reason to add that element
to the Iowa offense of assault with intent to commit sexual abuse when the Iowa offense
of sexual abuse itself does not require it. And the parties have not identified any caselaw
requiring that the defendant sought sexual gratification to commit assault with intent to
commit sexual abuse under Iowa Code § 709.11.
I agree with Defendant that the Iowa offense of assault with intent to commit sexual
abuse encompasses acts that may not be motivated by sexual gratification. 	Because the
Iowa offense is broader than SORNA’s definition of sex offense, Negrete-Vaca’s
conviction for assault with intent to commit sexual abuse does not categorically qualify
as a sex offense under SORNA. Thus, as a matter of law, Negrete-Vaca was not required
to register as a sex offender under SORNA, and I recommend that indictment be
dismissed.
III. 	CONCLUSION
I recommend GRANTING Negrete-Vaca’s motion to dismiss (Doc. 23).
