Rule 412 Excludes Minor Victim’s Sexting with Others; Similar Grooming Admissible Under Rule 404(b) to Prove Identity in § 2251(a) Cases

I. Introduction

In United States v. Andrew Boltz (7th Cir. July 20, 2026), the Seventh Circuit affirmed Andrew Boltz’s jury convictions for sexual exploitation of a minor under 18 U.S.C. § 2251(a). The case arose from Boltz’s online communications with a 16-year-old, “A.S.,” whom he met on Omegle and then moved to texting, calls, and Snapchat, where he repeatedly solicited sexually explicit images and videos.

On appeal, Boltz challenged several trial rulings: (1) exclusion under Federal Rule of Evidence 412 of evidence that A.S. sent nude images to other men; (2) admission under Rule 404(b) of clips from a police interview in which Boltz admitted grooming and exchanging explicit images with another minor (“M.C.”); (3) admission of A.S.’s mother’s testimony about A.S.’s vulnerability and demeanor; and (4) denial of a new trial based on alleged failure to preserve potentially exculpatory Snapchat evidence under Arizona v. Youngblood.

The opinion is notable for clarifying how rape-shield protections apply in child-exploitation prosecutions, for reaffirming that a “signature” grooming pattern can be used to prove identity under Rule 404(b) when the defense contests the actor behind the communications, and for emphasizing that victim-vulnerability testimony can be probative of § 2251(a)’s “persuaded, induced, or enticed” element.

II. Summary of the Opinion

  • Rule 412: The court held that evidence A.S. sent sexually explicit photos/videos to other men constitutes evidence of “sexual predisposition” and/or “other sexual behavior” under Rule 412(a) and was properly excluded. The court also found Boltz failed to comply with Rule 412(c)’s procedural requirements, which independently supported exclusion. Finally, exclusion did not violate Boltz’s right to present a complete defense because the evidence was not “central” to innocence.
  • Rule 404(b): The court held that video clips of Boltz admitting similar grooming conduct with M.C. were admissible for the non-propensity purpose of proving identity, given Boltz’s identity defense (suggesting someone else used the phone and sent the images). The similarities were sufficiently distinctive, and Rule 403 did not require exclusion.
  • Mother’s testimony: The court held the testimony about A.S.’s susceptibility and behavior was relevant and probative to whether she could be “induced or enticed” under § 2251(a), and it was not unfairly prejudicial.
  • Evidence preservation / new trial: The court found no bad faith by law enforcement and affirmed denial of a new trial under Arizona v. Youngblood.

III. Analysis

A. Precedents Cited

1. Anonymity of victims in sex-crime opinions

  • Doe v. Univ. of S. Ind., 172 F.4th 511 (7th Cir. 2026) and Doe v. Loyola Univ. Chi., 100 F.4th 910 (7th Cir. 2024) framed the court’s practice: adult litigants generally use real names, but courts often protect sex-crime victims’ anonymity. These cases did not decide the merits, but grounded the opinion’s use of initials for the victim.

2. Rule 412 (rape shield) scope and purposes

  • United States v. Young, 955 F.3d 608 (7th Cir. 2020) supported the understanding of Rule 412’s aims and the Seventh Circuit’s willingness to exclude victim sexual-history evidence as irrelevant to charged elements in child-sex cases.
  • United States v. Carson, 870 F.3d 584 (7th Cir. 2017) supplied the abuse-of-discretion standard for Rule 412 rulings and reinforced the irrelevance principle where sexual-history evidence does not bear on the charged mens rea/elements.
  • United States v. Baker, 157 F.4th 1215 (10th Cir. 2025) influenced the court’s classification analysis by treating sexual storytelling/fantasies as “predisposition” evidence under Rule 412(a)(2). The Seventh Circuit used Baker to support the broader proposition that sexually themed content (not only physical contact) can fall within Rule 412.
  • United States v. Ogden, 685 F.3d 600 (6th Cir. 2012) was central to the constitutional-rights discussion: even when Rule 412(b)(1)(C) is invoked, sexting with other people is not “critical” to defending an enticement charge focused on what the defendant induced in the charged incident.
  • Sun v. Xu, 99 F.4th 1007 (7th Cir. 2024) reiterated the policy foundations of Rule 412—avoiding embarrassment and stereotypical thinking— and helped justify exclusion as consistent with the rule’s purposes.
  • Chambers v. Mississippi, 410 U.S. 284 (1973) and Crane v. Kentucky, 476 U.S. 683 (1986) provided the constitutional framework: defendants have a right to present a complete defense, but only evidence “central” to a claim of innocence triggers the constitutional concern.
  • Stephens v. Miller, 13 F.3d 998 (7th Cir. 1994) (en banc) and United States v. Boyles, 57 F.3d 535 (7th Cir. 1995) supported strict enforcement of Rule 412’s notice-and-motion procedures as prophylactic rules preventing unfair surprise and protecting victims.
  • United States v. Cephus, 684 F.3d 703 (7th Cir. 2012) reinforced that irrelevant sexual history cannot be “smuggled in” via constitutional arguments.
  • United States v. Zephier, 989 F.3d 629 (8th Cir. 2021) was distinguished: there, prior-assault evidence was necessary to rebut expert testimony and support a consent defense. Here, the excluded evidence did not exculpate Boltz and did not rebut expert testimony.

3. Rule 404(b) identity and the non-propensity requirement

  • United States v. Gomez, 763 F.3d 845 (7th Cir. 2014) (en banc) supplied the controlling two-step approach: (i) relevance via a non-propensity chain of reasoning; (ii) Rule 403 balancing.
  • United States v. Taylor, 148 F.4th 896 (7th Cir. 2025) provided the abuse-of-discretion standard for Rule 404(b) determinations.
  • United States v. Norweathers, 895 F.3d 485 (7th Cir. 2018) was the opinion’s closest analogue. When a defendant claims “not me behind the account/device,” other communications evidencing child-sex interest can become probative of identity—because it makes it more likely the defendant, not a third party, used the account.
  • United States v. Brewer, 915 F.3d 408 (7th Cir. 2019), United States v. Zahursky, 580 F.3d 515 (7th Cir. 2009), and United States v. Chambers, 642 F.3d 588 (7th Cir. 2011) reinforced that “distinctive method of operation” can be used to establish identity or another permissible purpose, and that limiting instructions matter.
  • United States v. Price, 516 F.3d 597 (7th Cir. 2008) set a boundary: similarities must be distinctive, not generic “this is the defendant’s kind of crime.” The court used Price as a foil to explain why Boltz’s pattern was sufficiently idiosyncratic.
  • United States v. Johnson, 89 F.4th 997 (7th Cir. 2024) underscored how rarely appellate courts reverse on Rule 403 grounds.
  • United States v. Wantuch, 525 F.3d 505 (7th Cir. 2008) supported the proposition that evidence countering an anticipated central defense is highly probative under Rule 403.

4. Relevance/Rule 403 and element-proof evidence

  • United States v. Kapp, 419 F.3d 666 (7th Cir. 2005) supported admitting evidence probative of an element “in all but the most extreme cases,” which the court applied to A.S.’s mother’s testimony as element-directed proof of inducement/enticement.

5. Due process and preservation of evidence

  • Arizona v. Youngblood, 488 U.S. 51 (1988) supplied the governing due-process standard: failure to preserve potentially exculpatory evidence violates due process only upon a showing of bad faith.
  • Tabb v. Christianson, 855 F.3d 757 (7th Cir. 2017) articulated the Seventh Circuit’s Youngblood elements (bad faith, apparent exculpatory nature, and inability to obtain elsewhere).
  • United States v. Sabaini, 161 F.4th 1036 (7th Cir. 2025) provided the abuse-of-discretion standard for denial of a Rule 33 new-trial motion.

B. Legal Reasoning

1. Rule 412: sexting with others as “sexual predisposition”/“sexual behavior,” plus procedural enforcement

The court treated the proffered evidence—A.S. sending sexually explicit photos/videos to other men—as squarely within Rule 412(a)’s prohibitions. It reasoned the material had an obvious “sexual connotation” and thus fit “sexual predisposition” under Rule 412(a)(2), and it could also qualify as “other sexual behavior” under Rule 412(a)(1), consistent with the advisory committee’s broad conception (including sexual contact and “activities of the mind”).

Critically, the court focused on why Boltz offered the evidence: to argue that because A.S. voluntarily sent explicit material to others, she must have done so with him without inducement. That is the kind of inference Rule 412 is designed to block—turning a victim’s sexual history into a proxy for consent, willingness, or credibility.

The opinion also gave independent weight to Rule 412(c)’s procedures: a timely motion describing the evidence and purpose, service, and victim notice. Boltz’s mid-trial attempt to elicit the information (despite a pretrial warning) justified exclusion as a matter of prophylaxis and fairness, not merely relevance.

On the constitutional exception (Rule 412(b)(1)(C)), the court applied Crane v. Kentucky’s “central to innocence” requirement and found the excluded evidence non-central: the government’s burden under § 2251(a) was to show Boltz persuaded/induced/enticed A.S. to produce explicit material in the charged interactions. Whether she also sent explicit material to others did not negate Boltz’s requests or grooming, and it did not impeach the specific charged inducement.

2. Rule 404(b): “signature” grooming pattern as identity evidence once identity is contested

The court framed the dispute through the lens of an identity defense: Boltz’s cross-examination suggested the genital photos could depict someone else and that the examiner could not be sure who used the phone. Once identity became contested, the government could respond with non-propensity evidence tending to show that Boltz, in particular, was the person communicating with A.S.

The interview clips describing M.C. were admitted not to show “once a groomer, always a groomer,” but because the M.C. conduct shared a distinctive sequence and method: meeting minors on Omegle, shifting to Snapchat (with auto-deletion features), employing similar manipulative phrases and tactics, and exchanging explicit images. That pattern functioned like a “signature,” akin to the identity examples discussed in United States v. Beasley and the “distinctive method of operation” analysis in United States v. Brewer.

Under Rule 403, the court acknowledged the evidence was inflammatory but emphasized the distinction between “prejudicial” and “unfairly prejudicial.” The government minimized prejudice by using short, sanitized clips that omitted extraneous inflammatory content and images, and the district court issued limiting instructions. Consistent with United States v. Norweathers and United States v. Wantuch, the need to rebut a central defense increased probative value.

3. Victim-vulnerability testimony as element-directed proof (not sympathy)

The court treated A.S.’s mother’s testimony as relevant to § 2251(a)’s inducement/enticement element: the jury could consider whether A.S. was susceptible to the kind of attention, reassurance, and manipulation that grooming exploits. The court rejected the claim that the testimony was mere sympathy-building, concluding its probative value (element proof) was not substantially outweighed by unfair prejudice.

4. Evidence preservation: no Youngblood bad faith where deletion occurred before law enforcement involvement

Applying Arizona v. Youngblood and Tabb v. Christianson, the court affirmed the denial of a new trial because Boltz did not show bad faith. The record showed officers acted promptly to preserve what they could once they obtained the phone; deletion of Snapchat occurred before law enforcement involvement, and A.S. also stated Boltz asked her to delete messages. The court treated any “skew” from missing messages as insufficient absent the constitutional predicate of bad faith.

C. Impact

  • Stronger Rule 412 gatekeeping in digital communications cases: The opinion squarely applies Rule 412 to modern “sexting” evidence involving minors and underscores that “sexual predisposition” includes sexually explicit media and communications, not only physical sexual history.
  • Procedural compliance as a decisive battleground: By emphasizing Rule 412(c), the Seventh Circuit signals that litigants cannot “trial by ambush” on sensitive sexual-history evidence. Future defendants seeking the constitutional exception will need timely motions and specific proffers.
  • Rule 404(b) identity use in online exploitation prosecutions: The ruling reinforces that when a defendant disputes who used the device/account, prior similar grooming conduct may be admissible as identity evidence if the similarities are distinctive enough to move the inference from “his kind of crime” to “could not be anyone else’s crime.”
  • Broader admissibility of contextual vulnerability evidence: Testimony describing a minor victim’s isolation, social circumstances, and susceptibility may be admitted as element-relevant evidence of inducement/enticement—subject to Rule 403—likely encouraging more contextual proof in § 2251(a) trials.
  • Youngblood remains a high bar: Even where digital platforms auto-delete or accounts are deleted, defendants must show bad faith by law enforcement—not mere loss or incompleteness—to obtain relief.

IV. Complex Concepts Simplified

  • Rule 412 (“rape shield”): A rule that generally blocks evidence about a victim’s other sexual behavior or sexual predisposition when it is offered to suggest the victim was more likely to consent, was “the type” to do something sexual, or is less credible.
  • Rule 412(b)(1)(C) constitutional exception: Even if evidence falls under the shield, it may come in if excluding it would violate the Constitution. But the defendant must show the evidence is truly critical—“central”—to innocence, not merely helpful for character attacks.
  • Rule 404(b) propensity ban: The law generally forbids “he did it before, so he did it again” reasoning. Prior acts can be admitted only for other reasons—like identity, motive, intent, or absence of mistake.
  • “Signature”/modus operandi identity evidence: Prior-act evidence can prove identity if the common features are so distinctive that they identify the actor, not just the type of crime.
  • Rule 403 unfair prejudice: Evidence can be damaging to a defendant and still be admissible. The question is whether it risks an improper emotional or irrational verdict that substantially outweighs its legitimate probative value.
  • Youngblood bad faith: Missing or destroyed evidence does not violate due process unless law enforcement acted in bad faith (e.g., intentionally destroying evidence to prevent its use).

V. Conclusion

United States v. Andrew Boltz strengthens three practical propositions for Seventh Circuit trial practice in online child-exploitation cases: (1) sexually explicit communications or images a victim sent to others are classic Rule 412 material—both substantively barred and tightly policed procedurally; (2) once identity is contested, distinctive grooming patterns with other minors can be admissible under Rule 404(b) to prove identity, so long as the inference is non-propensity and survives Rule 403; and (3) contextual testimony about a victim’s vulnerability may be relevant to § 2251(a)’s inducement/enticement element. The decision also reaffirms that Youngblood relief requires bad faith, not simply the realities of deleted or unavailable social-media data.
