State v. Warfield (2026 S.D. 20): Alternative Assault Counts May Go to the Jury Without Double Jeopardy Where Only One Conviction Enters; Lost/Skipped Prison Video Is Judged Under Trombetta Absent Apparent Exculpatory Value

1. Introduction

In State v. Warfield, the Supreme Court of South Dakota affirmed the convictions of inmate Kelly D. Warfield for simple assault upon a correctional officer (SDCL 22-18-1(1) and 22-18-1.05) and intentional damage to property (SDCL 22-34-1(1)), arising from an incident at Mike Durfee prison. The central factual controversy was a four-second “skip” in prison surveillance footage occurring between Warfield’s destruction of prison property and the recorded moment when he began punching Correctional Officer Christopher Day.

On appeal, Warfield challenged (i) the State’s decision to charge assault, (ii) admission of the surveillance video, (iii) refusal of self-defense instructions, (iv) alleged suppression/failure to preserve additional video evidence (backup servers and a third camera angle), and (v) submission of two assault counts to the jury as multiplicitous and violative of double jeopardy. The Court rejected all claims.

2. Summary of the Opinion

  • Charging decision unreviewable absent due process concerns: The Court declined to review the prosecutor’s decision to charge simple assault because Warfield alleged no selective/discriminatory prosecution or other due process abuse.
  • Video exhibit challenge waived: Warfield affirmatively failed to object to Exhibit 1 and relied on it at trial; therefore, appellate review was waived.
  • No self-defense instruction required: Evidence did not support a reasonable belief that unlawful force or excessive force was imminent; officers acted within the scope of their duties in responding to Warfield’s property destruction and noncompliance.
  • No constitutional “access to evidence” violation: Missing/overwritten footage fell under California v. Trombetta, and Warfield failed to show apparent exculpatory value or prejudice; the record also undermined any Brady claim.
  • No double jeopardy violation from submitting alternative counts: Consistent with State v. Chavez and later cases, double jeopardy is concerned with multiple convictions/punishments, not the mere submission of alternative theories to the jury; Warfield was convicted of only one assault count.

3. Analysis

3.1 Precedents Cited

A. Prosecutorial discretion and limited appellate review

  • Commonwealth v. Cosby and People v. Herndon were cited for the broad, generally unreviewable nature of charging decisions, reviewable only for constitutional or legal contravention (e.g., arbitrary abuse, discrimination). Warfield’s argument (that the State “should have” charged only property damage because of the video skip) did not fit that mold.
  • State v. Tweeten reinforced deference to prosecutorial evaluation of evidence and charges.
  • The Court contrasted reviewable due process claims by citing People ex rel. W.Y.B. and State v. Muetze, both invoked to illustrate selective/discriminatory prosecution-type claims that could open the door to review—claims Warfield did not make.

B. Waiver/forfeiture of evidentiary claims on appeal

  • State v. Heer supplied the doctrinal hook distinguishing waiver (affirmative assent) from forfeiture (mere failure to object). The Court treated Warfield’s non-objection and strategic reliance on the video as affirmative waiver, ending the inquiry.

C. Self-defense instructions and the “law enforcement officer” limitation

  • State v. Tuopeh, State v. Schumacher, State v. Carter, and State v. Ortiz-Martinez were used to frame the standard of review (abuse of discretion) and prejudice requirement for instructional error.
  • People ex rel. N.A. was central: it articulates the rule that an individual is not justified in using force to resist “arrest or other performance of duty” by an officer acting within official duties; self-defense against an officer is limited to situations involving excessive force or actions outside lawful duty.
  • State v. Bruder and State v. Chamley supplied the baseline that defendants are entitled to theory-of-defense instructions only when supported by evidence; courts need not instruct on unsupported matters.

D. Access to evidence: Brady versus Trombetta categories

  • State v. Turner and State v. Zephier framed the constitutional right to present a complete defense and the “access to evidence” taxonomy.
  • Brady v. Maryland, State v. Peltier, and State v. Delehoy defined the elements of a Brady claim: favorability, suppression, and resulting prejudice.
  • California v. Trombetta supplied the test for destroyed/lost evidence where exculpatory value is unknown: the exculpatory value must have been apparent before destruction, and comparable evidence must be unavailable by other reasonably available means. The Court treated the overwritten third-camera footage and any hypothetical backup-server footage as belonging to this Trombetta category.

E. Double jeopardy, multiplicity, and alternative theories

  • State v. Chavez was Warfield’s anchor. The Court clarified Chavez’s core holding: while multiple charges may be brought, a defendant may not be punished more than once for the same offense based on identical facts under varying subsections of a statute absent legislative intent for multiple punishments.
  • State v. Johnson was cited for the three double jeopardy protections, focusing the analysis on the “multiple punishments” strand.
  • State v. Manning and State v. Washington supported the proposition that the State is not required to choose a single viable theory when evidence supports alternatives.
  • State v. Tuopeh (again) provided the modern synthesis: double jeopardy concerns center on multiple convictions/sentences, not on submitting multiple counts to the jury to meet the evidence that may be adduced.

3.2 Legal Reasoning

A. The Court’s jurisdictional posture toward charging decisions

The Court treated Warfield’s “shouldn’t have been charged because the video skipped” argument as a challenge to prosecutorial discretion, and—absent an alleged due process abuse such as selective or discriminatory prosecution—declined review. The key move is doctrinal: evidentiary weakness arguments are ordinarily tested through motions, trial, and sufficiency review, not by appellate second-guessing of initial charging choices.

B. Video admission: strategic use equals waiver

Because Warfield did not object to Exhibit 1 and used the four-second gap affirmatively to argue reasonable doubt, the Court found waiver. This reflects a practical appellate principle: a defendant cannot invite the jury to rely on an exhibit and then claim on appeal that the exhibit’s mere existence made the trial unfair.

C. Self-defense in a custodial setting: “unlawful force” and “excessive force” thresholds

Under SDCL 22-18-4, self-defense requires a reasonable belief that force is necessary against another’s imminent use of unlawful force. In the law-enforcement context, the Court relied on SDCL 22-18-2 and the limiting rule described in People ex rel. N.A.: force is not justified to resist an officer’s performance of duty; justification arises only if the officer uses excessive force or acts outside lawful duty.

Applying these standards, the Court viewed the officers’ “encircling,” commands to “cuff up,” and use of pepper spray as within the scope of duty given Warfield’s recent violent property destruction (hot pot strike at the front desk monitor; punching a wall-mounted TV) and failure to comply. Warfield’s own testimony largely disclaimed memory of the fight and did not supply concrete facts demonstrating excessive force. The inmate witness (Jones) did not see a punch by officers and described only the end-stage takedown—after the video resumes showing Warfield punching—which weakened any causal self-defense narrative.

D. Missing/overwritten video: why Trombetta, not Brady, controlled

Warfield framed the issue as a “Brady violation,” but the Court categorized the dispute as lost/destroyed evidence where exculpatory value was unknown: the third camera footage was overwritten in ordinary course, and the “skip” was attributed to bandwidth “bottlenecking” affecting recording itself. Under Trombetta, Warfield had to show (1) apparent exculpatory value before destruction and (2) inability to obtain comparable evidence by other reasonably available means.

The Court held Warfield failed at the first prong: nothing showed the third camera had direct sightlines or captured materially different content, and testimony suggested the “skip” would be present across versions (including any backup). The Court also emphasized that Warfield had two camera angles, multiple eyewitness accounts, and the opportunity (via a court order) to inspect servers—an opportunity that did not occur due to a breakdown with his expert. Finally, even under a Brady-style analysis, the Court found no prejudice: additional angle footage would not reasonably undermine confidence in the verdict given the existing evidence.

E. Alternative assault counts and double jeopardy

Warfield’s multiplicity argument rested on the idea that charging two simple-assault counts against the same officer, under different subsections, itself “subjected him to double jeopardy.” The Court rejected that framing. Drawing from Chavez, Washington, and Tuopeh, it clarified that double jeopardy’s multiple-punishment protection is violated when multiple convictions/sentences are entered for the same act, not when alternative counts are presented to the jury to match the proof. The jury acquitted Warfield on Count 2, convicted on Count 1, and he was sentenced only on the one assault conviction, eliminating the multiple-punishment concern.

3.3 Impact

  • Alternative-count charging is reinforced: The decision strengthens prosecutorial practice of pleading alternative statutory subsections and submitting them to the jury, so long as the court prevents multiple convictions/punishments for the same conduct.
  • Prison-video litigation is channeled into Trombetta’s framework: Where surveillance gaps are attributable to system limitations and missing footage is overwritten under routine retention policies, defendants face a high bar to show apparent exculpatory value and prejudice.
  • Self-defense against correctional officers remains narrowly cabined: The Court’s application of SDCL 22-18-2 and the People ex rel. N.A. limitation signals that generalized fear, “encircling,” or standard compliance tactics (including pepper spray) will not, without concrete excessive-force evidence, warrant self-defense instructions in custodial confrontations.
  • Appellate preservation lessons: The waiver holding underscores that defendants must object contemporaneously to evidentiary issues; strategic use of contested evidence at trial can foreclose appellate review.

4. Complex Concepts Simplified

Prosecutorial discretion
The prosecutor generally decides what charges to file. Courts usually do not second-guess that choice unless the defendant shows a constitutional problem like discrimination or retaliation.
Waiver vs. forfeiture
Forfeiture is failing to object; a court might still review for “plain error.” Waiver is affirmatively agreeing (or strategically embracing) the issue at trial; waived issues typically are not reviewed on appeal.
Brady v. Maryland
The State violates due process if it suppresses favorable evidence (exculpatory or impeachment) and that suppression prejudices the defense.
California v. Trombetta
When evidence is lost or destroyed (so its content is unknown), a due process violation requires that the evidence had clearly apparent exculpatory value before it was destroyed and that the defendant cannot get comparable evidence another way.
Multiplicity / double jeopardy (multiple punishments)
Charging multiple counts is not necessarily unconstitutional. The constitutional problem arises if the defendant is convicted/sentenced multiple times for the same offense based on the same act, absent legislative authorization.
Self-defense against an officer
Self-defense is not available to resist an officer’s lawful performance of duties. It becomes relevant only if the officer uses excessive force or acts outside lawful authority.

5. Conclusion

State v. Warfield consolidates several pragmatic criminal-law rules in South Dakota: (1) absent a due process abuse, appellate courts will not review the prosecutor’s decision to charge; (2) evidentiary objections must be preserved—strategic reliance can amount to waiver; (3) self-defense instructions are unavailable in custodial officer encounters without evidence of unlawful or excessive force; (4) missing prison video is evaluated under Trombetta when exculpatory value is unknown; and (5) submitting alternative counts to the jury does not itself create a double jeopardy violation where only one conviction and punishment results.
