What to expect in a South Dakota felony case, step by step

Many felony cases exist for weeks or months before anyone is charged. Detectives interview witnesses, execute search warrants, obtain phone and financial records, and — most consequentially — try to interview the person they are investigating.

This is the stage where the most damage is done and the most good can be accomplished. A person who declines to be interviewed and retains counsel immediately keeps every option open. A person who agrees to 'clear things up' typically supplies the strongest evidence in the eventual case.

Counsel involved at this stage can sometimes affect whether charges are filed at all, or what they are, by presenting information to the prosecutor before a charging decision hardens.

After arrest and booking comes an initial appearance, generally within a short time frame, where the court advises the defendant of the charges and rights, addresses counsel, and sets bond and conditions of release.

Bond arguments matter more than clients expect. Conditions such as no-contact orders, travel restrictions, alcohol monitoring, or employment requirements shape daily life for the entire pendency of the case, and violating any of them creates a separate problem regardless of the merits of the charge.

Where a defendant cannot afford bond, a motion to modify conditions can be filed, supported by employment verification, residence stability, family support, and a concrete supervision plan.

A felony charge must be tested for probable cause. In South Dakota this happens either at a preliminary hearing before a magistrate or through a grand jury indictment.

A preliminary hearing is an evidentiary proceeding at which the State must show probable cause to believe the offense occurred and the defendant committed it. The standard is low and most cases are bound over, but the hearing has independent value: it produces sworn testimony from key witnesses early, on the record, under oath, which can be used later to impeach shifting accounts.

Grand jury proceedings are different — they are one-sided and closed, and the defense does not participate. Whether the State proceeds by information and preliminary hearing or by indictment varies by county and by case, and it changes what early discovery looks like.

At arraignment on the information or indictment, the charge is formally read and a plea is entered. A not-guilty plea preserves everything: discovery, motions, negotiation, and trial. It is not a statement about the facts and it does not foreclose a later resolution.

Trial dates are typically set at or shortly after arraignment, and speedy-trial considerations begin to matter. Whether to press for the earliest date or to allow time for investigation is a strategic decision that should be made deliberately, not by default.

Discovery is where a case is actually learned. It includes police reports, but the reports are only the summary. The material that changes cases is the underlying data: body-worn and squad video, recorded interviews, dispatch and jail audio, forensic reports and the underlying laboratory bench notes, digital extractions from phones, photographs, and the officers' training and disciplinary records where obtainable.

The State also has a constitutional duty to disclose exculpatory and impeachment material. Whether that duty is fully satisfied is something the defense must actively test, not assume, through specific requests directed at known categories of material.

Independent investigation runs in parallel: locating and interviewing witnesses the State did not, visiting the scene, obtaining surveillance from private businesses before it is overwritten, and retaining experts where the State's evidence is technical.

Motions are the defense's opportunity to shape the trial before it starts. Motions to suppress challenge searches, seizures, statements, and identifications. Motions in limine seek to exclude prejudicial evidence. Motions to dismiss test the legal sufficiency of the charge. Motions for discovery sanctions address disclosure failures.

Even motions that are denied have value: they develop the record, produce sworn testimony, and demonstrate to the prosecution that the case will be litigated. Both of those affect what happens next.

The great majority of felony cases resolve by agreement. The terms depend on the strength of the evidence, the defendant's record, the county, the specific prosecutor, and — significantly — the credibility of the defense's willingness to try the case.

A resolution can involve the charge, the sentencing recommendation, or both. Agreements about sentencing recommendations are not always binding on the court, and the difference between a binding and non-binding agreement is something every client should have explained clearly before entering a plea.

Clients should also understand collateral consequences before pleading: firearm rights, professional licensing, immigration status, housing, employment, and any registration obligations. These are frequently more consequential over a lifetime than the sentence itself.

A felony jury trial follows a familiar structure: jury selection, opening statements, the State's case, the defense case if one is presented, closing arguments, instructions, and deliberation. The State bears the burden of proof beyond a reasonable doubt throughout, and the defendant is not required to present any evidence or to testify.

Jury selection is more important than television suggests. It is the only phase where the defense learns anything about the people deciding the case, and it is where cause and peremptory challenges are exercised.

The decision whether the defendant testifies belongs to the defendant alone, after advice from counsel. It is made near the end of the case, once the State's evidence is known.

If there is a conviction, sentencing typically follows a presentence investigation. The PSI is influential and frequently contains errors, and every disputed statement should be challenged on the record with documentation.

Effective sentencing advocacy is prepared, not improvised: evaluations, treatment records, employment verification, letters from credible people, and a specific plan the court can rely on. Judges respond to concrete plans far better than to general assurances.

Afterward come post-trial motions and appellate deadlines, which are short. If an appeal is being considered, that conversation should happen immediately, not weeks later.
