State v. West (Kan. 2026): Joinder Requires Multiple Commonalities; K.S.A. 60-455 Admissibility Not a Prerequisite

1. Introduction

In State v. West (Supreme Court of Kansas, July 24, 2026), Laroy M. West appealed convictions arising from two separate Wichita incidents: (1) a March 2021 confrontation at La Chinita restaurant resulting in aggravated assault and criminal possession of a weapon charges; and (2) a May 2021 confrontation outside a QuikTrip culminating in the shooting death of a security guard and charges including first-degree premeditated murder. West’s defense at trial was self-defense in both incidents.

The appeal centered on whether the district court should have severed the March and May charges, whether several jury instructions were erroneous (including an “initial aggressor” limitation on self-defense and lesser-included homicide instructions), and whether the court improperly excluded evidence (brass knuckles found among the victim’s belongings at the hospital) allegedly supportive of self-defense. West also asserted cumulative error.

2. Summary of the Opinion

The Kansas Supreme Court affirmed. It held that joinder was proper because the two sets of crimes were of the “same or similar character” under K.S.A. 22-3202(1), emphasizing that “same or similar” does not require identical offenses but does require multiple concrete commonalities, not just broad similarities or shared classification.

The court further held:

  • The denial of severance was not an abuse of discretion and did not prejudice West (reinforced by a “separate counts” instruction and the jury’s partial acquittal).
  • The “initial aggressor” instruction accurately stated Kansas law and was supported by evidence.
  • The refusal to instruct on heat-of-passion voluntary manslaughter was proper because the evidence did not reasonably support a heat-of-passion theory.
  • The involuntary manslaughter instruction was not clearly erroneous despite lacking an additional definition for “lawful act in an unlawful manner.”
  • Excluding evidence of brass knuckles did not violate the right to present a defense because the evidence was irrelevant and speculative.
  • With no error, cumulative error failed.

3. Analysis

3.1. Precedents Cited

The court’s joinder and instructional analyses were anchored in a line of Kansas decisions establishing both standards of review and substantive limits on joinder, self-defense limitations, and lesser-included instructions.

Joinder framework and “same or similar character”

  • State v. Ritz, 305 Kan. 956 (2017): Cited for the three-step joinder review and for affirming joinder despite factual differences between episodes where there are sufficient commonalities. West uses Ritz to illustrate that “same or similar” is not “identical,” but still fact-dependent.
  • State v. Smith, 312 Kan. 876 (2021): Cited for defining “substantial competent evidence” supporting factual findings in joinder review.
  • State v. Hurd, 298 Kan. 555 (2013): Cited for discretion at step two and for the prejudice inquiry at step three (reasonable probability of outcome impact).
  • State v. Carter, 311 Kan. 783 (2020): Cited for the substantial-rights prejudice concept (K.S.A. 60-261) in joinder error review.
  • State v. Barksdale, 266 Kan. 498 (1999) (quoting State v. Hodges, 45 Kan. 389 [1891]): Used to describe “same or similar character” in terms of “same general character,” mode of trial, kind of evidence, and kind of punishment.
  • State v. Bunyard, 281 Kan. 392 (2006), disapproved of on other grounds by State v. Flynn, 299 Kan. 1052 (2014): Cited for rejecting an overly narrow “clones” reading of “same or similar character.”
  • State v. Smith-Parker, 301 Kan. 132 (2014): Critical to the newly emphasized limit—joinder should rest on “multiple commonalities,” not mere generalities or classification.
  • State v. Cruz, 297 Kan. 1048 (2013), and State v. Gaither, 283 Kan. 671 (2007): Cited as examples where multiple overlaps (location/time, weapon, circumstances, identification) supported joinder and where limiting instructions and acquittals demonstrated juries can compartmentalize charges.
  • State v. Perez, 306 Kan. 655 (2017): Cited for the presumption that juries follow instructions, supporting the no-prejudice conclusion.

Joinder not dependent on K.S.A. 60-455 admissibility

  • State v. Smith-Parker, 301 Kan. 132 (2014) (quoting State v. Gaither, 283 Kan. 671 [2007]): The court again states a firm rule that joinder under K.S.A. 22-3202(1) is not contingent on whether evidence would be admissible as other-crimes evidence under K.S.A. 60-455.

Instructional-error framework and pattern instructions (PIK)

  • State v. Holley, 313 Kan. 249 (2021): Provides the three-step instructional-error framework (reviewability; legal/factual appropriateness; harmlessness).
  • State v. Broxton, 311 Kan. 357 (2020) and State v. Plummer, 295 Kan. 156 (2012): Cited on legal appropriateness—whether an instruction fairly and accurately states the law.
  • State v. Wimbley, 313 Kan. 1029 (2021); State v. Hollins, 320 Kan. 240 (2025) (quoting State v. Zeiner, 316 Kan. 346 [2022]); State v. Johnson, 321 Kan. 357 (2025); State v. Norris, 226 Kan. 90 (1979): These authorities underpin the court’s approach to “missing definitions”—the question is whether the instructions as a whole misled the jury or needed extra definitions for clarity, not whether the proposed addition would be correct in the abstract.

Initial aggressor/self-defense limitation cases

  • State v. Hunt, 257 Kan. 388 (1995) and State v. Beard, 220 Kan. 580 (1976): Longstanding approval of an initial aggressor instruction where the question is factual for the jury.
  • State v. Keys, 315 Kan. 690 (2022): Used to reject importing limitations into statutes (here, rejecting a “words alone can’t provoke” limitation not found in K.S.A. 21-5226[b]).
  • State v. Bernhardt, 304 Kan. 460 (2016): Cited to show West’s requested “mere words or gestures” language belongs to heat-of-passion voluntary manslaughter doctrine, not to K.S.A. 21-5226(b).
  • State v. Collins, 311 Kan. 418 (2020); State v. Salary, 301 Kan. 586 (2015); State v. Meyers, 245 Kan. 471 (1989); State v. Smith, 278 Kan. 45 (2004); State v. Adam, 257 Kan. 693 (1995); plus unpublished Court of Appeals cases State v. Mainville and State v. Miller: Cited to demonstrate that provocation/initial-aggressor status can arise from conduct short of first physical contact (e.g., rekindling conflict, returning with a weapon).

Heat-of-passion voluntary manslaughter line

  • State v. Thille, 320 Kan. 435 (2025); State v. Brownlee, 302 Kan. 491 (2015): Define “heat of passion” and frame when the instruction is warranted.
  • State v. Berkstresser, 316 Kan. 597 (2022) and State v. Williams, 295 Kan. 506 (2012): Establish the “some evidence” standard and that lesser-included instructions are not discretionary when supported.
  • State v. Gentry, 310 Kan. 715 (2019): Adequate provocation must satisfy an objective standard to reduce murder to voluntary manslaughter.
  • State v. Lowry, 317 Kan. 89 (2023) and State v. Johnson, 290 Kan. 1038 (2010): Ongoing or protracted disputes generally do not support heat-of-passion instruction.
  • State v. Graham, 275 Kan. 831 (2003) and State v. Hill, 242 Kan. 68 (1987): Examples where sudden quarrel/physical altercation immediately preceding the killing supported the instruction.

Involuntary manslaughter / imperfect self-defense

  • State v. Crosby, 312 Kan. 630 (2021): Defines clear-error burdens where no objection at trial.
  • State v. James, 309 Kan. 1280 (2019): Recognizes K.S.A. 21-5405(a)(4) as used in imperfect self-defense/excessive force settings.
  • Unpublished Court of Appeals cases: State v. Collins, No. 125,971 (2024); State v. Collins, No. 117,409 (2018); State v. Falcon, No. 81,121 (1999): Support the conclusion that no additional definition of “lawful act in an unlawful manner” is required when the instruction tracks the statute/PIK and self-defense is separately instructed.

Right to present a defense and relevance

  • State v. Smith, 320 Kan. 62 (2025); State v. White, 316 Kan. 208 (2022); State v. Waldschmidt, 318 Kan. 633 (2024): Frame the right to present a defense as limited to relevant, noncumulative, otherwise admissible evidence, reviewed de novo when constitutional claim is raised.
  • State v. Macomber, 309 Kan. 907 (2019): Provides the subjective/objective two-prong self-defense framework under K.S.A. 21-5222(b).
  • State v. Walters, 284 Kan. 1 (2007): Victim’s violent character can be relevant to the defendant’s state of mind when self-defense is raised.
  • State v. Alfaro-Valleda, 314 Kan. 526 (2022) and State v. McCormick, 305 Kan. 43 (2016): Explain materiality and probativeness within relevance analysis.

Cumulative error

  • State v. Guebara, 318 Kan. 458 (2024) and State v. Lowry, 317 Kan. 89 (2023): Cited for cumulative error doctrine and the rule that it does not apply where no errors are found.

3.2. Legal Reasoning

A. Joinder: “multiple commonalities” as a meaningful constraint

The opinion’s most consequential reasoning lies in the joinder discussion. While reaffirming that “same or similar character” is not a high bar (crimes need not be “clones”), the court stresses that joinder must be grounded in multiple specific overlaps, not mere generalities (e.g., “both involve violence” or “both are felonies”).

Applying that approach, the court catalogued overlaps that together justified joinder: proximity in time (five weeks), geographic proximity (blocks apart on North Broadway), similar setting (public-facing businesses), similar escalation pattern (verbal dispute escalating to threatened/used firearm), overlapping charges (aggravated assault and criminal possession in both incidents), and substantial identity evidence overlap (same cap/backpack/clothing, investigative linkage, later identification). Differences (assault vs. murder, severity level vs. off-grid) did not defeat joinder because the statute requires similarity of character, not identical harm.

B. Joinder is not a K.S.A. 60-455 gatekeeping exercise

West argued joinder effectively admitted propensity evidence that would fail K.S.A. 60-455 scrutiny. The court rejected this as a matter of Kansas law: under State v. Smith-Parker and State v. Gaither, joinder under K.S.A. 22-3202(1) is not dependent on whether each incident’s evidence would be independently admissible as other-crimes evidence. This maintains a doctrinal separation between the joinder statute’s efficiency/administration function and 60-455’s propensity safeguards.

C. Prejudice: compartmentalization instruction plus partial acquittal

Even assuming some arguable misstep, the court found no prejudice. It relied on: (1) the standard “each count is separate” jury instruction; (2) the presumption juries follow instructions; and (3) the jury’s acquittal on one May count as evidence it differentiated charges. This reinforces a recurring Kansas theme: absent strong indicia of spillover, limiting instructions and verdict differentiation often defeat prejudice claims.

D. Instructions: deference to PIK framing and “whole-instructions” review

For both the initial aggressor instruction (PIK Crim. 4th 52.240) and involuntary manslaughter (PIK Crim. 4th 54.180), the court treated conformity to PIK and the statute as a strong indicator of legal correctness. The court’s key methodological point is that missing definitional language is reversible only if, viewing instructions as a whole, the omission likely misled jurors.

E. Initial aggressor: provocation need not be physical contact

The court rejected West’s attempt to import a “words alone” limitation from Washington law and from Kansas voluntary manslaughter provocation doctrine into K.S.A. 21-5226(b). Kansas precedent allows provocation through conduct such as rekindling a conflict or returning to a confrontation in a way that foreseeably triggers violence. Evidence that West taunted Robinson from across the street after leaving the store was enough—however “slim”—to make provocation a jury question.

F. Heat-of-passion voluntary manslaughter: “totality” defeats suddenness narrative

Despite the short timeline, the court emphasized the continuous nature of the dispute and West’s own testimony indicating deliberation (unzipping backpack to access a firearm) rather than an impulsive loss of self-control. Thus, the evidence did not “reasonably justify” conviction on the heat-of-passion theory.

G. Right to present a defense: relevance and non-speculation

The brass knuckles evidence failed not because it related to self-defense in the abstract, but because it required speculation about how the victim came to possess them and because West did not know about them during the encounter. The court treated the proffer as neither probative nor material; it did not meaningfully inform the self-defense inquiry (which focuses on the defendant’s perceptions and a reasonable person standard, not the victim’s inner mindset absent a logical link).

3.3. Impact

A. A clearer joinder limiter: “multiple commonalities” is not optional rhetoric

Although the “multiple commonalities” concept existed in State v. Smith-Parker, State v. West operationalizes it as a practical constraint: prosecutors and trial courts should be prepared to articulate more than broad resemblance. The opinion signals that courts should identify several concrete overlaps—time, location, participants, modus, charges, investigatory linkage, or evidentiary overlap—rather than rely on “both involve guns” or “both are assaults.”

B. Reinforcement that joinder does not hinge on 60-455 analysis

The court again draws a bright line: a defendant cannot convert severance into a backdoor 60-455 exclusion argument. This predictably encourages joinder motions where statutory conditions exist, especially in cases with identity linkage across incidents.

C. Instruction litigation: “missing definition” arguments face an uphill climb

By leaning heavily on PIK compliance and “whole instructions” review, the court makes clear that appellate challenges premised on omitted definitional language—especially unrequested at trial—will rarely succeed absent a showing of genuine jury confusion or a misleading gap.

D. Self-defense evidentiary proffers: speculative “victim mindset” evidence is vulnerable

The brass knuckles ruling signals that evidence offered to prove a victim’s alleged aggressiveness must have a non-speculative chain of relevance to a material issue (often the defendant’s knowledge or the objective circumstances), not merely a character insinuation.

4. Complex Concepts Simplified

  • Joinder vs. severance: “Joinder” allows multiple charges to be tried together. “Severance” splits them into separate trials. Kansas uses a three-step appellate review: statutory permission, discretion, and prejudice.
  • “Same or similar character” (K.S.A. 22-3202[1]): Offenses do not have to be identical, but they must share several meaningful similarities. A single broad similarity (like “both involved a gun”) is not enough by itself.
  • K.S.A. 60-455 (other-crimes evidence): A rule limiting use of prior bad acts to show propensity. This opinion reiterates that joinder is not conditioned on passing 60-455 admissibility tests.
  • Initial aggressor limitation (K.S.A. 21-5226[b]): Self-defense is limited if a person provokes an attack intending to use that attack as a justification to harm the person provoked. Kansas does not require the provocation to begin with physical contact.
  • Heat of passion voluntary manslaughter: A homicide can be reduced if the killing occurred in intense emotion triggered by legally adequate provocation (measured objectively). Continuous disputes and deliberative conduct often defeat this theory.
  • “Lawful act in an unlawful manner” (K.S.A. 21-5405[a][4]): One way involuntary manslaughter can occur; in self-defense contexts it can describe using excessive force during otherwise lawful self-defense, but the court held juries need not receive that extra definition when properly instructed on self-defense and the statutory/PIK elements.
  • Right to present a defense: Constitutional, but not unlimited. Excluded evidence violates this right only if it is relevant, noncumulative, and otherwise admissible.

5. Conclusion

State v. West affirms convictions while sharpening Kansas joinder doctrine in practice: “same or similar character” is broad enough to include non-identical offenses, but joinder must rest on multiple specific commonalities, not vague resemblance. The court also reemphasizes that joinder is not dependent on K.S.A. 60-455 admissibility, reinforces the stability of PIK-based instructions under “whole instructions” review, and rejects speculative evidence offered under the banner of self-defense. Collectively, the opinion strengthens trial-court discretion to manage multi-incident prosecutions while insisting that the statutory bases for joinder be demonstrated with concrete, case-linked facts.
