State v. Blackwing (2025 UT 60): Intrinsic-Act Evidence Is Not “Other Act” Evidence Under Utah Rule of Evidence 404(b)

1. Introduction

In State v. Blackwing, the Utah Supreme Court reviewed (on interlocutory appeal) a district court’s in-limine order that largely excluded the State’s proposed “context” evidence in a prosecution for solicitation, conspiracy, and attempted aggravated murder. The State alleged that Kain Blackwing, while jailed awaiting trial in a sexual-assault case involving a fourteen-year-old victim (C.G.), directed three women with whom he had a polygamous relationship (Raven, Theresa, and Tina) to murder C.G. (and later her parents) to prevent testimony.

The key evidentiary dispute was whether details about (i) the underlying sexual-assault case involving C.G., and (ii) Blackwing’s alleged coercive, controlling relationship dynamics with the three women (including “cult-like” demands and threats), were admissible—particularly in light of Utah Rules of Evidence 401–403 and the “other acts” restriction in Rule 404(b). A related issue was whether the jury could be told that Blackwing had a prior rape conviction involving Tina.

2. Summary of the Opinion

• New/clarified rule adopted: The court held that acts “intrinsic” to the charged crime are not “other acts” within the meaning of Rule 404(b). Evidence is intrinsic (and outside Rule 404(b)) when it is an “integral and natural part” of the circumstances surrounding the charged offense or is “directly connected to the factual circumstances of the crime”.
• C.G. evidence: The district court correctly labeled the C.G. sexual-assault evidence as intrinsic, but it misapplied Rules 401–402 and 403 by excluding nearly all details. The Supreme Court reversed the blanket exclusion and held the State may present basic facts necessary to give the jury coherent context and allow evaluation of motive and narrative logic (subject to item-by-item Rule 403 rulings at trial).
• Tina prior conviction: The Supreme Court affirmed exclusion of evidence that Blackwing was convicted of raping Tina, holding that the conviction itself had little independent probative value and carried a substantial risk of unfair prejudice under Rule 403.
• Relationship/coercion evidence: The Supreme Court reversed the district court’s categorical exclusion of specific coercive acts (threats, punishments, “My Lord” requirement), holding that those acts were intrinsic to proving solicitation/conspiracy and that their probative value was not substantially outweighed by unfair prejudice.

3. Analysis

A. Precedents Cited

1) The intrinsic/extrinsic framework and Rule 404(b)

The decision’s doctrinal center is its adoption of an intrinsic-evidence rule that the court had previously acknowledged only cautiously. In State v. Lucero, the court had described (in a footnote) the federal concept that Rule 404(b) applies only to evidence “extrinsic” to the charged crime and that acts “inextricably intertwined” with the charged crime may fall outside the rule, citing United States v. Mower. But Lucero ultimately did not apply that framework on its facts, and later cases often avoided the question.

Here, the court recognizes that pattern explicitly: when the State previously invoked “intrinsic evidence,” the court often resolved admissibility through conventional Rule 404(b) analysis, as in State v. Allen and more recently State v. Andrus. By contrast, the Utah Court of Appeals had squarely treated integral-part evidence as outside Rule 404(b), as in State v. Sorenson (quoting State v. Hood) and State v. Main. Blackwing effectively aligns the Supreme Court’s approach with those appellate decisions and federal formulations.

For the intrinsic standard, the court relies heavily on federal definitions: United States v. Parker (intrinsic evidence is “directly connected” and provides contextual/background information; extrinsic is “extraneous”), and United States v. Irving (intrinsic evidence is an “integral and natural part” of circumstances). At the same time, it adopts a limiting principle from United States v. Bowie (as quoted in State v. Thornton at the court of appeals level): intrinsic does not include acts only “tangentially related” or used merely to “complete the story” or “explain the circumstances.”

The court also addresses skepticism expressed elsewhere. Blackwing urged adoption of a narrow intrinsic concept drawn from decisions like United States v. Green, United States v. Moore, and Rojas v. People that restrict intrinsic evidence largely to contemporaneous acts. Utah rejects that restriction, emphasizing that facilitative conduct often occurs before or after the crime, citing State v. Von Niederhausern and State v. Main as examples where later acts can still be intrinsic to proving the charged offense’s narrative logic.

Finally, the court distinguishes State v. Hood. In Hood, excommunication evidence did not facilitate the charged sexual offenses and was therefore not integral. In Blackwing, by contrast, the coercive household dynamic allegedly enabled the agreement (conspiracy) and the commands (solicitation), making it facilitative rather than merely character-revealing.

2) Standards of review and evidentiary “legal standard” errors

The court reiterates that evidentiary rulings are reviewed for abuse of discretion under State v. Ring, but that a district court abuses discretion if it applies the wrong legal standard, per State v. Cuttler. It emphasizes that identifying whether the correct legal standard was applied is reviewed for correctness, citing State v. Green. This framing matters because the court does not merely “rebalance” the evidence; it finds the district court used an incorrectly elevated relevance test and an infected Rule 403 analysis.

3) Relevance and narrative coherence under Rules 401–402

The court anchors relevance in Rule 401’s low threshold and reiterates (via State v. Martin) that even slight probative value suffices. It then draws from broader authorities to explain that evidence need not be element-by-element essential to be relevant: Old Chief v. United States is used to justify the admissibility of narrative evidence that gives “human significance” and maintains jurors’ willingness to draw necessary inferences. The court also cites United States v. Gonzalez for the proposition that evidence can be admitted even if it does not directly establish an element, and United States v. Boros for the concept that exclusion is problematic when it creates a “chronological and conceptual void.” Preservation doctrine is addressed via Gressman v. State.

4) Rule 403 unfair prejudice

On Rule 403, the court emphasizes a presumption of admissibility from State v. Green and uses State v. Johnson to define probative value (strength, consequential-fact probability shift, and need). It reiterates the classic caution from State v. Killpack that all effective evidence is “prejudicial” but not necessarily “unfairly” so. It uses Olympus Hills Shopping Ctr., Ltd. v. Smith's Food & Drug Ctrs., Inc. for a definition of unfair prejudice as decisions reached by improper means (sympathy, horror, instinct to punish, etc.). The “substantially outweighed” threshold is reinforced using State v. Alinas and State v. Kell.

The district court’s reliance on State v. Jaimez (child-sex-crime evidence being inflammatory) is not rejected as a general observation, but is treated as incomplete given the evidence’s direct role in explaining why the charged witness-murder scheme allegedly existed. Risk mitigation through limiting instructions is acknowledged by reference to MODEL UTAH JURY INSTRUCTIONS 2d CR411. For excluding the prior conviction, the court relies on the jury-abdication concern discussed in Robinson v. Taylor.

B. Legal Reasoning

1) The new Utah rule: intrinsic acts are not “other acts” under Rule 404(b)

The court rejects the idea that “intrinsic evidence” is a judicially created “exception” akin to res gestae. Instead, it treats the doctrine as textual: Rule 404(b) regulates “other” acts, not acts that are part of the charged crime’s factual circumstances. It then supplies an operational definition: evidence is intrinsic when there is a direct relationship between the act and the charged crime—when it is an “integral and natural part” of the surrounding circumstances or “directly connected to the factual circumstances.”

Importantly, the court calls the “inextricably intertwined” phrasing “unhelpful” and warns that relevance naturally implies some degree of “intertwining,” while “inextricable” suggests an unrealistically high bar. The doctrinal move is to replace a rhetorically powerful but vague phrase with a more functional “direct relationship/integral part” test.

2) Application to the C.G. evidence (Rules 401–402 and 403)

After holding the C.G. assault was intrinsic, the court finds the district court committed legal error by treating “relevant” as essentially “element-essential.” Under the correct Rule 401 standard, the nature and seriousness of the underlying case helps prove motive, makes the alleged murder plot more plausible, and prevents a narrative void. Under Rule 403, the court holds that while child-sex evidence is inflammatory, it is not “unfair” prejudice when it is tightly linked to the charged witness-silencing plot. The court nonetheless leaves room for the trial court to exclude needlessly graphic details on an item-by-item basis.

3) Application to relationship/coercion evidence (Rules 404(b) and 403)

The court treats the relationship evidence as intrinsic because it allegedly explains (i) how the conspiratorial agreement formed (conditioned compliance and fear), (ii) why Blackwing chose these specific individuals to execute the plan, and (iii) why they would act at his direction while he was in jail—countering an anticipated “they acted alone” theory. By reclassifying the evidence as intrinsic, the court removes the district court’s “proper inference vs propensity inference” weighing that had been conducted under a 404(b) lens. The Rule 403 analysis then becomes more straightforward: given the evidence’s centrality to proving solicitation/conspiracy, probative value is “at its zenith,” and the remaining prejudice is largely the legitimate force of the evidence.

4) The Tina conviction (Rule 403)

The court draws a sharp line between conduct evidence relevant to relationship/control and the fact of conviction. It holds the conviction itself adds no meaningful probative value beyond “another factfinder credited that evidence,” and it risks the jury substituting the prior jury’s conclusion for its own. Under Rule 403, that risk substantially outweighs probative value, so exclusion is affirmed.

C. Impact

• Doctrinal clarity in Utah evidence law: Blackwing formally adopts an intrinsic-evidence doctrine for Rule 404(b), ending a long period where the Supreme Court acknowledged the concept (e.g., State v. Lucero) but often avoided relying on it (e.g., State v. Allen, State v. Andrus).
• Expanded admissibility of tightly connected context evidence: Prosecutors (and defendants) can now argue more directly that certain background facts are not “other acts” when they are integral to explaining motive, agreement formation, facilitation, or why events unfolded as alleged—especially in conspiracy/solicitation cases where relationship dynamics matter.
• Continued gatekeeping via Rules 401–403: The opinion does not create a free pass. Courts must still apply Rule 401’s low threshold correctly and perform authentic Rule 403 balancing, with attention to tailoring (excluding gratuitous details, limiting cumulative proof, and issuing limiting instructions where appropriate).
• Sharper skepticism toward “conviction” evidence: Even if the underlying conduct is admissible, the fact of conviction may be excluded where it invites jury abdication and undue prejudice, reinforcing a practical separation between proving conduct and proving adjudication.

4. Complex Concepts Simplified

Rule 404(b) (“other acts” evidence)

Generally bars using a defendant’s other wrongs to prove “they’re the kind of person who would do this.” It allows other-act evidence only for non-character purposes (motive, intent, plan, etc.).

Intrinsic vs. extrinsic acts

After Blackwing, Utah treats acts as intrinsic (and not governed by Rule 404(b)) when they are directly connected to the charged crime or are an integral and natural part of the surrounding circumstances. If the act is only tangential or merely “story completing,” it is not intrinsic.

Rules 401–402 (relevance)

Evidence is relevant if it has any tendency to make a consequential fact more or less likely. It need not be indispensable to proving an element; it can supply context that makes the narrative coherent and the inferences rational.

Rule 403 (unfair prejudice)

Even relevant evidence can be excluded if its probative value is substantially outweighed by unfair prejudice—meaning it pushes jurors to decide for improper reasons (horror, sympathy, punishment instinct) rather than the evidence tied to the legal questions.

Why “conviction” evidence is different from “conduct” evidence

A prior conviction can cause jurors to defer to the prior verdict rather than independently evaluate the proof. So, even when the underlying conduct is admissible for context, the conviction may still be excluded as unfairly prejudicial.

5. Conclusion

State v. Blackwing is a significant Utah evidence decision because it squarely holds that intrinsic acts are not “other acts” under Rule 404(b) and provides a workable definition focused on direct connection and integral-part facilitation, while rejecting vague “inextricably intertwined” rhetoric. Applying that framework, the court broadens admissibility of the underlying C.G. case facts and the coercive-relationship evidence as central context for proving solicitation and conspiracy, yet simultaneously reinforces Rule 403’s role by affirming exclusion of the prior rape conviction and by permitting trial courts to trim gratuitous details through item-by-item rulings.
