Subdivision 4 combines five demanding propositions

The State must prove a criminal assault; great bodily harm; causation; a statutorily protected official performing a duty imposed by law, policy, or rule; and either use of a dangerous weapon or actual or attempted deadly force.

Each proposition is independent. A weapon and serious injury do not prove intent. Great harm and official employment do not prove a covered duty. Deadly circumstances do not prove the accused was the actor.

Subdivision 4 is not simply subdivision 3 with a weapon found nearby. The assault and great harm must be connected to use of the dangerous weapon, or the State must prove the actual-or-attempted-deadly-force alternative.

The complaint should identify the object, manner of use, force theory, injury category, official status, duty, and causal mechanism. Alternative pleading is permitted, but it must give meaningful notice.

The offense applies to conduct on or after its effective date. Earlier cases about dangerous weapons and great harm interpret definitions; they do not necessarily describe the current 25-year minimum enacted in 2021.

Probable cause can rest on preliminary medical and forensic information, but trial proof cannot. A charge filed while an official is in critical care may require reevaluation when recovery, laboratory testing, or complete video changes the factual foundation. Ongoing discovery is substantive, not clerical.

The charging date also matters because the 2021 legislation applies prospectively. A prosecutor cannot use the later mandatory structure for earlier conduct merely because treatment or prosecution continued after the effective date.

The State must prove fear assault or harm assault

Minn. Stat. § 609.02, subd. 10 (2026) defines fear assault as an act done with intent to cause fear of immediate bodily harm or death. Harm assault is the intentional infliction of or attempt to inflict bodily harm.

A completed great-injury case ordinarily relies on harm assault. The physical act must be volitional, but the prosecution does not have to prove a purpose to cause the precise degree of injury.

Fear assault remains specific intent. If injury results from flight or a defensive reaction, the State must prove both the intent to create immediate fear and criminal causation.

Possessing or displaying a weapon is not automatically assault. Context must show the required immediate-fear intent or intentional/attempted infliction of bodily harm.

Severe injury cannot substitute for the intentional act. Reflex, seizure, accidental discharge, vehicle malfunction, being pushed into the official, or another actor’s force can negate assault or identity.

Fear and harm alternatives should not be mixed casually. Fear assault requires a purpose to cause immediate fear; harm assault requires an intentional physical act. Evidence sufficient for one is not necessarily sufficient for the other, and voluntary intoxication has different relevance.

The injury must satisfy one of four great-bodily-harm categories

Great bodily harm means bodily injury creating a high probability of death, causing serious permanent disfigurement, causing permanent or protracted loss or impairment of a bodily member or organ, or constituting other serious bodily harm.

The State needs one category, but should identify it. A fracture is expressly included in the lower “substantial bodily harm” definition and is not automatically great harm.

Hospitalization, surgery, unconsciousness, scarring, blood loss, and work absence are relevant without being conclusive. The actual injury and longitudinal recovery matter.

Medical experts should distinguish possibility from a high probability of death, an open wound from final disfigurement, discomfort from functional impairment, and several lesser injuries from other serious bodily harm.

The defense can acknowledge a real injury while contesting the statutory threshold. That is not an admission to assault, weapon use, official status, or causation.

“Other serious bodily harm” must be read in context with the listed categories. The totality may include blood loss, unconsciousness, surgery, multiple wounds, shock, and continuing effects, but the phrase cannot erase the Legislature’s lower substantial-harm level.

Follow-up evidence is important. A feared permanent deficit may resolve; an injury initially thought minor may produce lasting nerve or organ impairment. The most reliable record includes the complete course, not only the moment most favorable to either side.

A dangerous weapon can be defined by design or by manner of use

Section 609.02, subdivision 6, includes any firearm, loaded or unloaded; a device designed as a weapon and capable of producing death or great bodily harm; combustible or flammable liquid; another device or instrumentality used or intended in a manner calculated or likely to produce death or great bodily harm; and fire used to produce death or great bodily harm.

The categories matter. A firearm qualifies by statute. A knife or club designed as a weapon must also be capable of the required harm. An ordinary object depends on manner of use or intended use.

“Dangerous” in everyday speech is not the legal test. The object or use must be tied to death or great bodily harm, not merely pain or ordinary injury.

Size, weight, material, edge, point, speed, force, target area, number of blows, distance, and surrounding physical conditions affect classification.

The jury may decide disputed facts about use; courts decide legal instruction. Photographs and measurements are better than labels such as “blunt object.”

An object can fall into more than one category, but jurors should not be told that every object capable of some serious misuse is automatically a dangerous weapon. The ordinary-object clause focuses on this use or intended use. Almost any household item can injure; the statute demands more.

Cars, boots, bottles, tools, furniture, and other ordinary objects

An object not designed as a weapon can become one through use. Minnesota cases have analyzed boards, boots, pool cues, bottles, bats, hammers, hatchets, scissors, vehicles, and many other items.

The same object can be a dangerous weapon in one event and not another. A boot used to walk is not a weapon; repeated forceful kicks to a person’s head may transform its role. A slowly moving car used only to depart differs from a vehicle deliberately driven at a person.

The actual manner is critical when great bodily harm occurred through a different mechanism. An object held during a fall is not necessarily the instrument that caused injury.

Intended use can matter even when the act is interrupted. Statements, grip, concealment, preparation, swing, direction, and distance may show intent, but equivocal handling is not enough merely because the item could be dangerous.

Hands and feet are part of the body rather than separate instruments in ordinary analysis. Clothing or footwear can become an instrumentality depending on facts, while deadly-force theory may apply independently of object classification.

Location on the body matters. One blow to an arm with a light object is different from repeated overhead strikes to the head. The actual injury can corroborate force but should not become circular proof: great harm alone does not establish that every object present was used dangerously.

Firearms qualify whether loaded or unloaded, but connection to the assault still matters

A firearm is expressly a dangerous weapon. The State need not prove it was loaded for that definition, though operability and design can still be litigated in unusual cases.

Presence is not use. A holstered firearm, a gun in a vehicle, or a weapon possessed by someone else does not establish that the assault and great harm were inflicted “with” it.

Pointing, striking with, firing, threatening with, or using a firearm to force movement can connect it to assault. Subdivision 4 also independently covers actual or attempted deadly force.

Ballistics, cartridge cases, bullet fragments, trajectory, residue, blood, fingerprints, DNA, magazine condition, safety position, and video can establish or refute use.

A replica, BB gun, airsoft device, or inoperable object may be a dangerous weapon under some facts but is not automatically a firearm under every Minnesota statute. Laboratory identification should precede a legal conclusion.

When a firearm is recovered after several people handled the scene, chain of custody matters. A DNA mixture or absent fingerprint does not identify a shooter by itself. Magazine capacity, fired-cartridge count, bullet defects, and synchronized audio can test witness accounts.

Deadly force and dangerous weapon are overlapping but different concepts

Subdivision 4 incorporates Minn. Stat. § 609.066, subd. 1 (2026). Deadly force is force the actor uses with a purpose to cause, or should reasonably know creates a substantial risk of causing, death or great bodily harm.

Intentional firearm discharge toward a person or at an occupied vehicle is statutorily deadly force, subject to the less-lethal-munition official-duty exception.

Deadly force can involve no separate object: strangulation, stomping, dropping someone from height, or force against a vulnerable body area can create the required substantial risk.

A dangerous weapon can be displayed for fear assault without actual deadly-force application. Conversely, bodily force can be deadly without a weapon. The verdict should reveal the supported alternative when legally important.

“Substantial risk” is more than a theoretical possibility. Mechanism, duration, force, anatomy, distance, and what the actor should reasonably have known require evidence.

The actor’s purpose and the objective risk are alternative portions of the definition. Force used with a purpose to cause death or great harm can qualify even if fortuity prevents the anticipated risk; force without that purpose can qualify when the actor should reasonably know it creates the substantial risk.

Attempted deadly force can satisfy subdivision 4 even when the attempt did not cause the injury

The text includes using or attempting to use deadly force while requiring that the assault inflict great bodily harm. The State must prove both the completed injury and the attempted-deadly-force aggravator, but the statutory wording does not necessarily require the attempted mechanism alone to have produced the harm.

An attempt requires intent and conduct crossing beyond mere preparation. Drawing, aiming, pulling a trigger, accelerating, swinging, or manipulating a device may qualify depending on context.

Possession, anger, threatening words, or preparatory movement alone may be insufficient. The court must instruct the line between preparation and attempt.

Malfunction or factual impossibility does not automatically defeat an attempt if intent and a substantial step are proved. It remains relevant to what the accused believed and whether the act was equivocal.

The defense should identify the exact attempted act and ask whether it was directed against the protected official rather than property, escape, or another person.

Jury instructions should not permit conviction for an “attempt to attempt.” The assault may itself be an attempted harm assault, while the aggravator may be attempted deadly force. The court must identify the conduct and mental state without lowering either requirement.

The assault must cause great harm, and the aggravating weapon or force must fit the incident

Criminal causation generally requires the assault to be a substantial causal factor. It need not be the only cause, and an unusual vulnerability does not automatically relieve liability.

Subdivision 4 also requires the qualifying weapon or force relationship. If great harm resulted from an accidental fall after a separate display, the State must prove its legal theory rather than joining unrelated facts.

Multiple assailants, several weapons, restraint by officials, collisions, medical complications, and later incidents can create alternate causes. Accomplice liability needs separate proof.

A superseding cause can break the chain if it intervenes, changes the natural sequence, and alone produces a result that otherwise would not have occurred. Ordinary treatment or rescue usually does not qualify merely because imperfect.

Biomechanics, pathology, ballistics, vehicle reconstruction, and synchronized video can connect or disconnect the alleged instrument from the diagnosed injury.

Subdivision 4’s wording can produce a difficult case when one act causes great harm and a separate act allegedly constitutes attempted deadly force. Timing, criminal objective, and statutory construction should be litigated rather than assuming that any two acts during the episode may be combined.

Only defined peace officers, prosecutors, judges, and correctional employees qualify

“Peace officer” incorporates Minn. Stat. § 626.84, subd. 1 (2026). Licensing, appointment, law-enforcement duties, and arrest authority should be proved.

“Prosecuting attorney” includes the attorney general and elected or appointed county and city attorneys with criminal or civil responsibilities, plus their deputies, assistants, and special assistants.

“Judge” means a judge or justice of a Minnesota court established by the state constitution. “Correctional employee” means an employee of a public or private prison, jail, or workhouse.

Probation officers, reserve officers, federal agents, security guards, transport contractors, and secure-treatment staff can be protected elsewhere without necessarily fitting subdivision 4.

Uniform, badge, location, and employer testimony help, but the statutory category should be established with proper records rather than assumed.

Knowledge of status can affect perception and intent even when status itself is objective. Plain clothes, masks, unmarked vehicles, a dark cell, cross-commands, hearing limitations, and a sudden entry may alter whether the accused understood the encounter and acted defensively.

The official must be performing a duty imposed by law, policy, or rule

The official need not be making an arrest. Covered duties can include investigation, supervision, transport, security, courtroom work, prosecution, civil legal responsibility, evidence protection, and emergency response.

The State should identify the source of duty. Statutes, agency policy, post orders, assignments, court schedules, job descriptions, and testimony can establish it.

A mistake or policy violation does not automatically turn duty into private action. Excessive force and unlawful conduct can support defenses without necessarily negating employment duty.

A personal dispute, private errand, or off-duty frolic may fall outside the element. Off-duty intervention may still be a statutory duty under particular facts.

Workers’ compensation or internal “line of duty” labels use other standards and do not conclusively prove the criminal element.

Policy evidence can cut both ways. It may establish that an employee was assigned to restrain, transport, search, or intervene. It may also show that the encounter had shifted into an unauthorized personal confrontation or that force escalated contrary to the role being performed.

Intent differs across assault, weapon, and attempt theories

Harm assault requires an intentional physical act, not a purpose to cause the final injury. Fear assault requires intent to cause fear of immediate bodily harm or death.

An ordinary-object dangerous-weapon theory depends on how the object was used or intended to be used. An attempted-deadly-force theory requires intent for the attempt and conduct beyond preparation.

The State should not use great injury as automatic proof of intent. Accident, involuntary movement, reflex, medical event, third-party force, and mechanical failure can negate the act.

Whether knowledge of official status must be separately instructed is a legal issue to assess in the specific case. What the accused perceived remains relevant to intent, self-defense, and identification.

Voluntary intoxication has a limited role for specific intent and is not a broad defense to general-intent harm assault.

Accomplice liability requires intentional aid, advice, hiring, counseling, or conspiracy under Minnesota law. Presence, association, knowledge that another is armed, or failure to intervene is not automatically enough. The aggravating weapon and injury facts must be attributed through a valid theory.

Self-defense, excessive force, accident, and mistaken identity

Self-defense requires an actual and reasonable belief in imminent danger, necessary and proportional force, absence of aggression, and compliance with applicable avoidance rules. Deadly-force defense is governed by section 609.065 and controlling precedent.

A belief that an arrest is legally invalid does not alone authorize force. An official’s excessive force can support a limited defensive response, but deadly force demands evidence of qualifying imminent danger.

Accident can defeat assault, weapon use, or causation. It does not mean merely that an intended strike had an unintended consequence.

Group and vehicle cases can present mistaken identity. DNA mixtures, ownership, driver status, presence, and proximity do not independently prove who used the instrument.

Even when some assault is admitted, the defense can contest great harm, dangerous-weapon use, deadly force, official status, duty, and subdivision 4’s connection among them.

Self-defense should be evaluated moment by moment. Initial defensive force may be justified while later force after withdrawal is not; conversely, an official’s escalation may create a new danger. A single narrative label can hide those changes.

Physical evidence should establish object, use, injury, and sequence

Preserve the object before alteration. Record dimensions, weight, material, edge, damage, blood, fibers, DNA, fingerprints, serial number, operability, and chain of custody.

Collect every body, squad, jail, courthouse, business, traffic, and bystander camera. Wide-angle distortion and obstructed body-camera views require comparison with scene measurements.

Medical records should include original imaging, ambulance notes, surgery, follow-up, therapy, scar development, functional testing, prognosis, and relevant prior baseline.

Vehicle cases need event data, GPS, steering, braking, acceleration, tire marks, mechanical inspection, and position reconstruction. Firearm cases need ballistics, trajectory, discharge residue, cartridge cases, and function testing.

Dispatch, use-of-force reports, policies, witness interviews, and first spontaneous statements can reveal changes in mechanism. Experts may explain science but cannot decide the legal elements.

Original files matter. Exported video may omit frames or metadata, screenshots omit context, and enhanced images can introduce artifacts. A defensible reconstruction retains source media, documents processing, synchronizes clocks, and states uncertainty.

Medical terminology also needs translation. “Critical,” “stable,” “serious,” and “life-threatening mechanism” are often clinical or administrative terms. The provider should explain the diagnosed injury and risk rather than borrowing the statutory conclusion.

Subdivisions 2 and 3 are not merely duplicate charges

Subdivision 2 requires actual or attempted deadly force against a protected official but no completed great harm. It carries a 10-to-20-year mandatory range.

Subdivision 3 requires great bodily harm to a protected official but no weapon or deadly force. It carries a 15-to-25-year mandatory range.

Subdivision 4 combines great harm with a dangerous weapon or actual/attempted deadly force and carries 25 to 30 years. The added element must be proved, not inferred from the injury.

Ordinary first-degree assault, second-degree dangerous-weapon assault, fourth-degree official assault, obstruction, fleeing, weapons offenses, and attempted murder may also be alleged. Attempted murder separately requires intent to kill.

Lesser offenses, alternative verdicts, and multiple punishment under Minn. Stat. § 609.035 (2026) require count-specific analysis.

A rational lesser verdict can preserve accountability without the 25-year minimum when one aggravating element fails. The defense should request instructions supported by the record rather than force jurors into an all-or-nothing choice between subdivision 4 and acquittal.

Subdivision 4 requires an executed 25-to-30-year term

The statutory maximum is 30 years and the maximum fine is $40,000. Subdivision 5 requires commitment for not less than 25 nor more than 30 years.

The court may not stay imposition or execution. The statute restricts probation, parole, discharge, work release, and supervised release until the full term is served as provided by law.

The current Sentencing Guidelines offense table ranks subdivision 4 at severity level 11 and flags special duration treatment. The statutory range remains controlling.

A firearm allegation may also implicate section 609.11, but punishment cannot be stacked mechanically. Convictions, enhancements, and one behavioral incident must be analyzed together.

Restitution, firearm ineligibility, immigration consequences, licensing, civil exposure, and no-contact conditions may extend beyond prison. Precise plea and verdict language matters.

The offense is also treated as a severe violent crime for Guidelines purposes. Criminal-history scoring, custody status, consecutive-sentence rules, and other counts can change total exposure, but no Guidelines calculation may exceed the 30-year statutory maximum for the count.

Minnesota cases require attention to the actual use and actual injury

In State v. Fleck, 810 N.W.2d 303, 309–12 (Minn. 2012), the Supreme Court held that harm assault requires an intentional physical act but not a purpose to cause the particular result. Involuntary movement is insufficient.

In State v. Dye, 871 N.W.2d 916, 922–24 (Minn. App. 2015), the precedential Court of Appeals held that a gunshot’s actual route and injury—not what it might have struck—control the high-probability-of-death inquiry.

The official archived opinion State v. Garcia, No. A03-602, 2004 WL 771307, at *2 (Minn. Ct. App. Apr. 13, 2004) (nonprecedential), explains that even an inherently dangerous object must be considered with the manner of its use when applying the dangerous-weapon definition.

Another official archived decision, State v. Riebe, No. C1-97-985, 1998 WL 204562, at *2–3 (Minn. Ct. App. Apr. 28, 1998) (nonprecedential), illustrates that mere possession during an assault is different from using or intending to use an object as the assault weapon.

These authorities address component definitions. A subdivision 4 case must fit all components together under the current statute and mandatory-sentence structure.
