What to Do If You’ve Been Charged With Conspiracy or Are Under Federal Investigation in South Dakota

Above all else, follow this rule: never speak to law enforcement without an attorney. Investigators are focused on building a case, and even casual statements can be used to support a conviction.

Federal conspiracy cases often begin long before anyone is arrested. Compared to state-level cases in South Dakota, federal investigations often proceed discreetly over long periods of time, relying on informants, surveillance, financial analysis, and electronic communications.

You may be the subject of a federal investigation if:

Being contacted by federal agents seeking an interview or informal conversation
Receiving a subpoena demanding documents, emails, phone records, or financial information
Federal search warrants carried out at residences, workplaces, or storage facilities
Discovering that associates or others connected to you have been arrested or charged
Receiving a target letter or grand jury notice

Even seemingly harmless statements can be portrayed as evidence of participation in a conspiracy. Prosecutors frequently use early statements to form the backbone of federal conspiracy cases.

An experienced federal defense attorney in South Dakota may be able to:

Step in during the investigation stage before formal charges are brought
Communicate with investigators and prosecutors on your behalf
Clarify your legal status as a witness, subject, or target
Help prevent self-incrimination
Begin shaping a defense strategy early in case you are charged
Build a defense team that includes independent investigators and experts

Prompt legal guidance in federal conspiracy cases can make the difference between extreme sentencing exposure and protecting your future.

An experienced South Dakota federal defense lawyer can:

Taking action during the investigation stage before an indictment
Serving as your point of contact with investigators and the U.S. Attorney’s Office
Explaining your legal position within the federal investigation
Reducing the risk of self-incrimination during an investigation
Begin shaping a defense strategy early in case you are charged
Build a defense team that includes investigators and experts to challenge the government’s case

In federal conspiracy cases in South Dakota, early legal guidance can be the difference between decades behind bars or being able to move on with your life quickly.

When Does a Crime Become a Federal Conspiracy?

Under federal law (18 U.S. Code § 371), the government must prove three factors in order to gain a conviction on a conspiracy charge:

Agreement: An agreement exists between two or more individuals to commit a federal offense or defraud the United States, such as submitting false tax returns.
Criminal Intent (Mens Rea): Prosecutors must prove that the accused voluntarily joined the agreement while understanding its unlawful objective.
An Overt Act in Furtherance of the Conspiracy (in most cases): A member of the alleged conspiracy commits an act, even a minimal one, in furtherance of the agreed-upon plan.

Because conspiracy is a separate offense, an individual can face charges regardless of whether the planned crime was completed.

The alleged agreement does not have to be written or explicit and may be inferred from actions, conversations, or surrounding circumstances. This flexibility is why conspiracy statutes are so aggressively applied in federal criminal cases.

To be charged with conspiracy, you do not have to:

Personally carry out the alleged federal offense
Know all alleged co-conspirators
Take part in all aspects of the alleged conspiracy
Receive money or benefits

Even limited or indirect involvement can be portrayed as participation in a conspiracy, particularly when prosecutors argue that actions were “reasonably foreseeable” within the scope of the agreement.

Types of Federal Conspiracy Charges We Defend in South Dakota

Rather than charging conspiracy alone, federal prosecutors frequently rely on conspiracy allegations to widen responsibility, escalate potential penalties, and pursue complex multi-defendant prosecutions. Combs Waterkotte’s experienced South Dakota federal conspiracy defense lawyers represent individuals accused of conspiracy in a broad spectrum of federal cases, including:

Federal drug conspiracy cases brought under 21 U.S.C. § 846, where charges may proceed even if no drugs were seized or personally handled
Mail and wire fraud conspiracy charges under 18 U.S.C. §§ 1343, 1341, commonly supported by emails, financial records, and government interpretations of intent
Healthcare, bank, and financial fraud conspiracies, frequently driven by document reviews and government interpretations of business practices
White-collar conspiracy allegations such as tax-related conspiracies and money laundering conspiracy under 18 U.S.C. § 1956(h)
RICO conspiracy and enterprise conspiracy charges under 18 U.S.C. § 1962(d), even when no individual racketeering acts are attributed to a specific defendant
Public corruption and bribery conspiracy under 18 U.S.C. §§ 201 and 666, often relying on circumstantial evidence of intent or agreement
Conspiracy charges involving murder or violent federal crimes under 18 U.S.C. § 371, § 1959, or related statutes, regardless of whether violence was carried out

Penalties for Federal Conspiracy Charges

Federal conspiracy convictions frequently carry serious penalties comparable to those associated with the substantive offense. Federal law allows courts to impose the same penalties for conspiracy as for the completed offense, regardless of whether the alleged crime was finished.

Federal conspiracy charges carry a maximum sentence of up to five years in prison. Many federal statutes contain separate conspiracy provisions, including those governing drug and money laundering conspiracies, permitting penalties identical to the underlying offense and mandatory minimum terms.

Potential penalties in federal conspiracy cases in South Dakota may include:

Prison terms determined by the substantive offense connected to the alleged conspiracy
Mandatory minimum sentencing requirements in drug, firearms, or other offense-specific conspiracies
Substantial financial penalties, including fines and restitution orders
Forfeiture of assets allegedly connected to the conspiracy
Terms of supervised release imposed after any prison sentence

Federal courts in South Dakota also rely on the U.S. Sentencing Guidelines, which focus on the overall scope of the alleged conspiracy rather than an individual’s isolated actions. Sentencing determinations often involve consideration of:

How long the alleged conspiracy lasted and its overall scope
The number of alleged participants and each person’s role
Whether the defendant is accused of leadership or organizational responsibility
Conduct committed by co-conspirators that was reasonably foreseeable

Federal conspiracy sentencing can expose individuals in South Dakota to punishment for actions taken by co-conspirators. Identifying and challenging these sentencing drivers is a critical part of any federal conspiracy defense.

Defenses to Federal Conspiracy Charges in South Dakota

A successful federal conspiracy defense in South Dakota begins with a thorough evaluation of the evidence and the prosecution’s theory of the case. Based on the specific allegations, potential defenses can include:

No Agreement
An actual agreement must be shown, and parallel conduct or casual communications do not, by themselves, prove a conspiracy.
Lack of Knowledge or Intent
A defendant cannot conspire to commit a crime they did not knowingly or intentionally agree to participate in.
Presence Alone or Association
Simply being around alleged co-conspirators or having relationships with them is insufficient to prove conspiracy.
Withdrawal as a Defense
Demonstrating withdrawal before further acts occurred may limit or eliminate liability in certain cases.
Weak or Unsubstantiated Evidence
Many conspiracy cases rely on cooperating witnesses, informants, wiretaps, or circumstantial evidence that may be challenged for credibility or legality.
Violations of Constitutional Rights
When law enforcement violates constitutional protections, critical evidence may be excluded or charges thrown out.

Skilled South Dakota federal conspiracy defense lawyers focus not only on trial strategy, but also on early motions and challenges designed to weaken the government’s case.
