The federal criminal process in South Dakota involves multiple steps, from investigation to trial. Most federal agencies such as the FBI, DEA, and Homeland Security handle these cases. Each stage has strict deadlines and follows the federal rules of procedure, which differ from state court cases.
Understanding these steps helps defendants prepare for what’s ahead.
| Federal Charges | State Charges |
|---|---|
| Handled in federal court | Handled in state court |
| Investigated by federal agencies (FBI, DEA, ATF) | Investigated by local or state police |
| Often involve crossing state lines or national boundaries | Usually happen within a single state |
| Higher penalties and mandatory minimums | Sentences follow state law |
A case is sent to federal court when the alleged crime crosses state lines, affects federal interests, or violates federal law. This often includes crimes like drug trafficking, wire fraud, or offenses that involve federal agencies. The U.S. Attorney’s Office handles prosecution in these cases.
Several federal agencies operate across South Dakota. The FBI investigates violent crimes and national security issues. The DEA focuses on drug possession and trafficking cases. The IRS handles financial crimes like tax fraud, while Homeland Security looks at border and immigration offenses. The ATF investigates firearms and explosives-related crimes.
Federal judges use the Federal Sentencing Guidelines to decide sentences. These guidelines assign points based on the type of crime, criminal history, and harm caused. Many federal crimes have mandatory minimums, meaning the judge must give a certain amount of prison time. These rules often lead to steep fines and long sentences.
Under 21 U.S.C. § 841, it is a federal crime to make, distribute, or have controlled drugs like meth, heroin, or cocaine. Even trying or agreeing with others to traffic drugs is illegal under 21 U.S.C. § 846. Sentences depend on how much and what kind of drug is involved under 21 U.S.C. § 841(b).
The law also allows the government to take any money, homes, or property linked to drug activity under 21 U.S.C. § 853. These crimes often lead to long prison terms and very high fines.
White collar crimes involve using lies or false information for financial gain. Mail fraud under 18 U.S.C. § 1341 and wire fraud under 18 U.S.C. § 1343 cover schemes using mail or electronic communication. Money laundering, listed under 18 U.S.C. § 1956, punishes moving money earned from crimes.
18 U.S.C. § 1957 makes it illegal to make large financial transactions with illegal funds. Stealing from federal programs, such as tribal or nonprofit funds, is a crime under 18 U.S.C. § 666. Convictions often include big fines, restitution, and prison time.
Under 18 U.S.C. § 922(g), certain people like felons or those convicted of domestic violence cannot own or carry guns. Using or carrying a firearm during a crime brings extra penalties under 18 U.S.C. § 924(c). Selling or moving firearms illegally is punished under 18 U.S.C. § 922(a).
Violations of the National Firearms Act, including having unregistered weapons or silencers, are charged under 18 U.S.C. § 5861. These laws are strict, and sentences are often long and mandatory.
Serious sexual offenses on federal or tribal land are handled under federal law. 18 U.S.C. § 2241 punishes aggravated sexual abuse, such as using force or threats. 18 U.S.C. § 2242 covers sexual acts without consent, and 18 U.S.C. § 2243 addresses sexual abuse of minors.
Under the Major Crimes Act (18 U.S.C. § 1153), these cases in Indian Country are handled in federal court. Penalties can include long prison terms and lifetime registration as a sex offender.
Crimes in Indian Country often fall under special laws. The General Crimes Act (18 U.S.C. § 1152) gives the federal government power to handle crimes involving non-Native people in tribal areas. The Major Crimes Act (18 U.S.C. § 1153) covers serious offenses committed by Native Americans, such as murder, assault, or sexual abuse.
The Indian Civil Rights Act (25 U.S.C. § 1302) sets rules for fair treatment under tribal law, though tribal courts have limited sentencing power.
Even though South Dakota sees fewer immigration crimes, they are still serious. Returning to the U.S. after being deported is illegal under 8 U.S.C. § 1326, and using or making false immigration documents is a crime under 18 U.S.C. § 1546. These crimes often lead to deportation, prison time, and permanent bans from entering the U.S. again.
Cybercrimes include hacking, stealing information, and committing fraud online. Under 18 U.S.C. § 1030, it is illegal to access computers or networks without permission. Identity theft, under 18 U.S.C. § 1028, punishes using someone’s personal data for crime.
Access device fraud under 18 U.S.C. § 1029 covers credit card and online payment scams. Wire fraud, under 18 U.S.C. § 1343, applies to online or digital fraud. Penalties can include years in prison and large fines.

The federal criminal process includes several key steps before a verdict is reached. Defendants must attend hearings, review evidence, and decide whether to go to trial or take a plea deal. Every phase follows the federal rules and can take months to complete.
After an arrest, the defendant goes before a federal judge for the first hearing. The court decides if bail is allowed or if the person stays in custody during the case.
Both sides exchange evidence, known as discovery. A skilled federal criminal defense attorney can file motions to dismiss or challenge certain evidence that was collected improperly.
Many federal cases end in plea deals where the defendant agrees to plead guilty for a reduced sentence. If not, the defense prepares for trial, reviewing all evidence and witness statements.
At trial, both the defense and prosecution present their cases to a jury. The prosecutors must prove guilt beyond a reasonable doubt. A skilled South Dakota federal criminal defense lawyer helps you tell your side clearly and strongly.
If convicted, the judge uses the federal sentencing guidelines to set the punishment. Defendants can file appeals to the South Dakota Supreme Court or federal appellate courts to challenge unfair outcomes or legal errors.
A crime becomes federal when it violates federal law, crosses state lines, or involves federal agencies.
