The statute protects four different functions

Minnesota’s degrees use different means, but the prohibited objectives repeat:

1. preventing or dissuading a person from attending or testifying;
2. causing or attempting to cause false testimony;
3. preventing or dissuading a person from giving law enforcement information about a crime; and
4. causing or attempting to cause false information to law enforcement.

First-degree and aggravated first-degree provisions also punish retaliation. A charge should identify the objective, not merely allege “tampering.” Asking someone not to attend a hearing differs from asking the person to lie. Discouraging a police report differs from retaliation after one. Each theory has its own timing and proof.

Actual success is not required for prevention, dissuasion, coercion, or influence theories because the statute expressly reaches attempts. A witness may testify truthfully, report immediately, ignore the speaker, or never receive an indirect message, yet an attempt charge may still be alleged if the defendant intentionally took a qualifying act.

A protected person need not already be subpoenaed

The attendance and testimony provisions protect a person who “is or may become a witness.” That phrase reaches a victim, eyewitness, records custodian, expert, family member, investigating officer, informant, or other person whose information could lead to testimony even before a prosecutor files a witness list.

Police-information clauses are broader in another way. They protect a person providing information concerning a crime, whether or not a trial is pending or the person ultimately testifies. The State must still connect the intended interference to information about a crime rather than an unrelated personal dispute.

For retaliation based on testimony, first degree requires that the person was summoned as a witness. Retaliation based on police information requires that the person actually provided it. The complaint should use the correct alternative and prove the status that alternative demands.

Trials, proceedings, inquiries, and criminal-law limits

Ordinary first, second, and third-degree testimony alternatives cover a trial, proceeding, or inquiry authorized by law. That can include criminal, civil, family, juvenile, grand-jury, administrative, or other legally authorized matters depending on the facts.

Aggravated first degree is narrower for the attendance, testimony, and summoned-witness retaliation alternatives: those provisions refer to a criminal trial or proceeding. The police-information alternatives still concern information about a crime. A civil deposition threat may fit first degree but not necessarily aggravated first degree unless the charged statutory alternative is satisfied.

The State should identify the proceeding or inquiry. An informal workplace meeting, private mediation, news interview, or family discussion is not automatically an “inquiry authorized by law.” Other offenses may apply, but statutory language controls.

First-degree witness tampering: force or threats of injury

First degree applies when force or threats of injury to any person or property are used to prevent or dissuade testimony or police information, or to coerce false testimony or false information. It also applies to specified retaliatory injury or threats. The maximum is five years and a $10,000 fine.

The threatened target need not be the witness. Threats against a child, partner, relative, pet, vehicle, home, business property, or another person can supply the prohibited means if used with the required witness-related intent. “Injury” includes property injury under the statutory text; it is not limited to bodily harm.

The State must prove a threat, not merely anger, criticism, pleading, or prediction. Tone, history, conditional wording, gestures, access to weapons, prior violence, location, and audience may give ordinary words a threatening meaning. Conversely, a harsh statement extracted from an argument may lack the charged witness-related purpose.

Aggravated first-degree witness tampering: great bodily harm or death

Aggravated first degree requires causing great bodily harm or death, or an implicit or explicit credible threat to cause great bodily harm or death, while intentionally committing one of the six listed tampering or retaliation acts. The maximum is twenty years and a $30,000 fine.

A threat need not use the words “kill” or “great bodily harm.” It can be implicit. But it must be credible and concern the statutorily serious result. Credibility is evaluated in context: ability, prior conduct, detail, timing, access, relationship, and how the communication would reasonably be understood may matter. The listener’s fear is relevant evidence but does not alone prove the speaker’s intent or every element.

Great bodily harm has a demanding statutory meaning involving a high probability of death, serious permanent disfigurement, permanent or protracted impairment, or other serious bodily harm. A threat of unspecified trouble should not automatically be elevated to the twenty-year offense.

Causing harm and threatening harm are distinct aggravated theories

The aggravated statute covers actual causation as well as credible threats. If the State alleges actual great bodily harm or death, it must prove the injury level and causal connection to the intentional tampering act. Medical records, forensic evidence, expert testimony, and alternative causes become central.

If the State alleges a threat, it must identify the communication and why it was credible. A conditional statement, lyric, meme, vague social post, report of what another person supposedly will do, or description of lawful consequences may not carry the same meaning as a direct promise of violence.

The jury should know which theory it is deciding. A verdict cannot blur actual harm, an explicit threat, and an implicit threat if the alternatives raise distinct factual disputes or affect unanimity.

Second-degree witness tampering uses three specific coercive threats

Second degree is a gross misdemeanor. It incorporates only clauses (3), (4), and (5) of Minnesota’s coercion statute, section 609.27:

• a threat unlawfully to injure a trade, business, profession, or calling;
• a threat to expose a secret or deformity, publish a defamatory statement, or expose a person to disgrace or ridicule; or
• a threat to make or cause a criminal charge, whether true or false, subject to the statute’s good-faith law-enforcement warning language.

A threat to report truthful misconduct can still be coercive in a private context when used to manipulate testimony or police information. But a lawyer’s legitimate statement that evidence will be presented, or a good-faith report of crime, is not automatically tampering. Purpose, wording, authority, and demanded result matter.

Third-degree witness tampering uses intimidation

Third degree is a misdemeanor and applies when intimidation is used to prevent or dissuade testimony or police information, or to influence false testimony or false information. It operates unless a greater degree applies.

The statute expressly permits proof of intimidation through a specific act or the totality of circumstances. Intimidation may arise from repeated contact, physical presence, reputation, relationship control, coded language, surveillance, gestures, prior abuse, group affiliation, or a combination that would carry meaning beyond isolated words.

Not every uncomfortable conversation is intimidation. A request, emotional appeal, expression of disappointment, assertion of innocence, or effort to obtain truthful information does not become criminal merely because the recipient felt pressure. The State must connect the conduct, intimidation, and intended falsehood or noncooperation.

Witness tampering is a specific-intent offense

The actor must intend the prohibited witness-related result. In State v. Collins, 580 N.W.2d 36, 43–44 (Minn. App. 1998), review denied (Minn. July 16, 1998), the court held that “a single act can support a witness-tampering conviction.” It upheld the conviction based on a threatening letter sent to a crime victim in the circumstances of a pending case.

Intent is usually circumstantial. Evidence may include references to a case, witness, subpoena, trial date, police contact, desired recantation, alibi, changed account, or consequences of cooperation. Timing close to a report, interview, hearing, or release from custody may be probative.

Alternative purposes deserve real analysis. A defendant may be trying to repair a relationship, arrange property, discuss parenting, express anger, ask for truthful correction, or comply with counsel’s investigation. Mixed motives do not automatically defeat specific intent, but the State still must prove the prohibited purpose beyond a reasonable doubt.

Asking for truth is lawful; pressuring a person to lie is not

A person may ask a witness to tell the truth, correct an actual mistake, preserve evidence, or speak with an investigator voluntarily. Defense lawyers and investigators routinely interview willing witnesses. The criminal line is crossed when qualifying threats, force, coercion, or intimidation are used for a prohibited result.

“Drop the charges” can be legally and factually imprecise because witnesses generally do not control prosecution. In context, it may mean decline to cooperate, recant, request dismissal, or simply express a wish. The State should prove what the speaker intended the recipient to do.

A claimed request for truth can be pretextual if paired with a script, threat, reward, destruction request, or demand to deny known facts. The complete exchange matters more than a label supplied later.

Attempt liability requires more than talk or preparation

The statute itself includes attempts to prevent, dissuade, coerce, or influence. Minnesota’s general attempt statute may also be charged in some settings, producing difficult questions when the underlying tampering alternative already contains attempt language.

In State v. Jenkins, No. A25-1580, slip op. at 12–23 (Minn. App. Sept. 8, 2026) (nonprecedential), the Court of Appeals reversed attempted aggravated first-degree tampering because discussions with a cellmate had not advanced beyond preparation toward preventing testimony. The court affirmed third-degree tampering based on evidence that another person was enlisted to pressure a witness to recant.

Jenkins is recent and nonprecedential. It expressly declined to decide whether “attempted aggravated first-degree witness tampering” is a cognizable offense. Its narrower lesson is useful: proof of a plan is not automatically proof of a substantial step, while indirect action actually carried out can support a completed intimidation theory.

Retaliation is separately prohibited after testimony or police cooperation

First degree and aggravated first degree cover specified retaliatory injury or threats. For a summoned witness, the protected period extends one year after the trial, proceeding, or inquiry or one year after the actor’s release from incarceration, whichever is later. For a person who gave law-enforcement information, it extends one year after the information or one year after release, whichever is later.

The release language can extend exposure far beyond the underlying event. The State should prove the incarceration and release date, the protected act, and the causal retaliatory purpose. A later conflict between people with a long history is not automatically witness retaliation.

Retaliation differs from an effort to change future testimony. The former punishes injury or threat because of what the person already did; the latter seeks to alter future participation. A complaint may allege both, but jury instructions and verdict forms should distinguish the theories.

Indirect threats and intermediaries can support a charge

A defendant need not personally contact the witness. A message can travel through a relative, friend, cellmate, social-media account, group conversation, lawyer, investigator, or coded public post. The State must prove attribution, intended communication or influence, and the intermediary’s role.

An intermediary can misunderstand, exaggerate, improvise, or act independently. Obtain the original communication, not only the recipient’s retelling. Compare wording, timestamps, deleted portions, call recordings, and each participant’s motive. If the alleged threat never reached the witness, an attempt theory may remain possible, but the State must prove the defendant’s intended result and qualifying act.

Agency is not assumed merely because people know one another. Evidence that the defendant requested, directed, approved, or later adopted the intermediary’s conduct matters. A third party’s unsolicited threat should not automatically be attributed to the accused.

Domestic-abuse cases require context without automatic assumptions

Witness-tampering allegations frequently arise in domestic-assault, order-for-protection, harassment, and criminal-sexual-conduct cases. Relationship history can give coded statements a threatening or intimidating meaning that would be invisible in isolation. It can also create overlapping disputes about children, housing, property, finances, and reconciliation.

No-contact orders may prohibit communication regardless of message content. A consensual response by the protected person does not necessarily authorize the defendant’s contact. But violating a no-contact order and tampering are separate questions; tampering requires the witness-related intent and means specified by section 609.498.

Prosecutors may rely on recorded jail calls and third-party messages when a witness recants. Recantation alone does not prove the accused caused it. The defense should examine prior accounts, outside pressures, financial dependency, family influence, police interview methods, and the witness’s own reasons.

Lawful witness contact, defense investigation, and counsel

Witnesses do not belong to either party. Unless prohibited by court order or law, a defense investigator may request a voluntary interview, identify the client, explain that participation is optional, and ask for truthful information. The witness may decline or seek counsel.

Lawyers must not advise a witness to ignore a subpoena, conceal evidence, lie, or evade lawful process. They may explain rights, privileges, risks, and procedures. Careful documentation protects both the witness and defense team from later mischaracterization.

A represented person, child, vulnerable adult, government employee, or alleged victim may implicate additional ethical and procedural rules. Counsel should make contact through proper channels and avoid using the client or family members as informal investigators when an order forbids contact.

Jail calls, texts, disappearing messages, and social media

Custody calls are routinely recorded. Defendants may use account numbers belonging to others, coded names, three-way calls, or requests that a listener relay a message. Authentication can use voice identification, account records, call timing, contextual details, and subsequent conduct.

Text and social-media evidence should be collected in native form. Screenshots can omit account identifiers, replies, edited text, disappearing-message settings, timestamps, and surrounding conversation. Subpoenaed provider records, device extractions, backups, and witness testimony can confirm or undermine attribution.

Deleting a message after learning of an investigation can create consciousness-of-guilt arguments and separate evidence issues. Preserve devices and accounts. Do not contact a witness to “clear things up” after a tampering allegation; the follow-up may become a new count.

Speech rights do not protect true threats or criminal intimidation

Witness-tampering charges often depend on words, but the First Amendment does not immunize force, true threats, coercion, or intimidation used to corrupt legal participation. At the same time, criticism of a prosecution, assertion of innocence, political speech, public discussion of a case, and lawful requests for truth remain protected or innocent in proper context.

The court should separate offensive content from the charged criminal function. A vulgar insult may be constitutionally protected yet relevant context; a polite-sounding coded message may be criminal if the shared history gives it a credible threatening meaning.

Overbroad charging can chill lawful defense investigation and family communication. Precision about the intended result and prohibited means protects the justice system without turning every case-related conversation into tampering.

Whether a threat was credible requires the full factual setting

Aggravated first degree uses the word “credible.” The prosecution should not equate disturbing language with a credible threat of death or great bodily harm without showing why the communication could reasonably carry that force. The accused’s ability to act is relevant, but physical distance or incarceration does not automatically defeat credibility when an intermediary, outside associate, weapon access, or detailed personal information is alleged.

The defense should examine specificity, immediacy, conditional wording, prior conduct, audience, relationship, cultural or linguistic meaning, intoxication, mental state, and later actions. A witness’s reaction can help explain meaning, but a subjective fear response cannot replace proof of what was threatened and why it was credible.

Implicit-threat cases require particular care. Shared history may turn an ordinary phrase into a serious threat, yet a court should demand evidence of that shared meaning rather than speculation. Prior incidents offered to supply context raise notice, relevance, proof, and unfair-prejudice issues. Limiting instructions may be necessary so jurors use prior conduct to interpret the statement, not simply to conclude that the defendant is a bad person.

Account ownership is not the same as authorship

A phone number, social-media profile, jail account, or return address can point toward a sender without conclusively proving who composed or transmitted the message. Phones are shared, accounts are accessed from several devices, friends relay messages, and incarcerated people sometimes use another person’s calling credentials.

Attribution evidence can include voice identification, device possession, login history, IP records, location, writing style, fingerprints, handwriting, contextual facts known only to participants, and conduct after transmission. The defense should obtain the underlying records and test whether alternative users had access at the relevant time.

Alteration is another concern. Cropped screenshots, renamed contacts, copied text, missing replies, stitched audio, translation, and paraphrased voicemail can change meaning. Native extraction and provider records often show whether the exhibit is complete. Even when authorship is proved, the State must separately prove witness-related intent and the means required for the charged degree.

Evidence: preserve the whole conversation and relationship history

Core evidence includes recordings, texts, direct messages, letters, envelopes, call logs, video, location data, witness interviews, subpoenas, police reports, court calendars, release records, medical evidence, property damage, weapon access, and prior communications that explain coded language.

Start with chronology. When did the accused learn of the report or witness? When was a subpoena issued? When did communication occur? What happened before and after? Who initiated contact? Was a message forwarded accurately? Did the witness change an account, miss court, or continue cooperating?

Preserve exculpatory context too: requests to tell the truth, disclaimers, efforts to avoid prohibited contact, unrelated reasons for communication, proof an account was shared or compromised, and evidence that an intermediary acted alone. Attribution and intent should not be assumed from a displayed username.

Statements to police and recorded confrontation calls

Investigators may arrange a recorded call or message in which the witness asks why the defendant made a threat or requested a recantation. The answers can be admissions, denials, ambiguity, or attempts to calm the situation. The recording should be evaluated as an investigative technique, not treated as self-interpreting.

A defendant should not guess about prior conversations in a police interview. Investigators may know the exact recording and ask broad questions first. Counsel can obtain discovery, identify counts, and assess whether any voluntary statement is advisable.

Witness interviews also require care. Repeated law-enforcement or family questioning can affect memory and wording. Record the earliest account, exact questions, promises, threats, benefits, and whether the witness reviewed messages before describing them.

Charging notice, alternative theories, and jury unanimity

The complaint should identify the person, protected activity, intended result, means, communication, date, and degree. It should distinguish attendance, false testimony, police information, false police information, and retaliation.

Where several conversations or acts are alleged, the court must decide whether they are one continuing course, separate offenses, or evidentiary facts. Jurors should not convict while disagreeing about which distinct act occurred if unanimity law requires agreement.

Aggravated facts require clear findings: actual great bodily harm or death, or an implicit or explicit credible threat of that result. Second degree must identify one of the three incorporated coercion clauses. Third degree must identify intimidation under the specific act or totality theory.

Assault, threats, harassment, coercion, and no-contact violations

The same communication may produce charges for assault, threats of violence, harassment, stalking, coercion, domestic-assault no-contact-order violation, order-for-protection violation, or witness tampering. Similar evidence does not make the elements identical.

Subdivision 4 expressly permits an aggravated first-degree tampering conviction and punishment alongside other crimes despite the usual statutory rules. For ordinary first, second, and third degree, Minnesota’s normal conviction and single-behavioral-incident rules still require analysis.

Multiple messages can also produce multiple counts, but the unit of prosecution should be tested. Repetition may prove intimidation or intent without necessarily making every text a separate completed offense.

Current penalties and Minnesota Sentencing Guidelines

The statutory maximums are:

• twenty years/$30,000 for aggravated first degree;
• five years/$10,000 for first degree;
• gross-misdemeanor punishment for second degree; and
• misdemeanor punishment for third degree.

The Minnesota Sentencing Guidelines offense table ranks first-degree witness tampering at Severity Level 5 and aggravated first degree at Severity Level 9. Criminal history, custody status, attempt, multiple offenses, weapons, departures, and plea terms affect the presumptive sentence.

Witness tampering can also affect pretrial release, no-contact orders, bail, probation, supervised release, phone privileges, and the underlying case. A new allegation may be used to seek detention even before conviction. The statutory maximum is not the same as the presumptive prison term.

A disciplined defense separates message, meaning, intent, and degree

Build a communication ledger listing every call, text, visit, post, intermediary, recipient, and claimed instruction. Preserve native evidence and obtain full recordings. Identify missing messages, edits, account access, translation, sarcasm, and relationship context.

Map each alleged act to a statutory alternative. Was the objective nonattendance, false testimony, withheld police information, false police information, or retaliation? What supplied the means: injury, threat, coercion clause, intimidation, or a credible great-harm or death threat? Was the person protected under that alternative?

Then test intent, credibility, causation, substantial step, timing, and attribution. The question is not whether the communication looked bad. It is whether admissible evidence proves the exact degree and theory beyond a reasonable doubt.
