If you’ve been charged with a crime in Missouri, one of the most important parts of your case happens long before the trial begins — the discovery process. Discovery is how both sides, the prosecution and the defense, share evidence and information about the case.

Understanding how discovery works can make the difference between a strong defense and a conviction. Here’s what you need to know, and why hiring an experienced Kansas City criminal defense lawyer is critical.

WHAT IS DISCOVERY?

In criminal law, “discovery” refers to the exchange of evidence between the prosecutor and the defense before trial. It ensures fairness by giving both sides access to the information they need to prepare their case.

In the state of Missouri, prosecutors must disclose specific types of evidence to the defense. This transparency prevents surprises at trial — like suddenly revealing evidence or witnesses the other side hasn’t had time to investigate.

WHAT EVIDENCE MUST THE PROSECUTION SHARE?

The prosecution in Missouri must turn over any evidence that could be relevant to the case. This includes:

Police reports and investigation notes
Witness statements and contact information
Body-camera and dash-camera footage
Photos, videos, and physical evidence
Lab results (such as DNA, fingerprints, or drug analysis)
Defendant’s statements (anything you said to police)
Criminal history records of witnesses

Most importantly, prosecutors must share any exculpatory evidence — that is, evidence that could help prove your innocence or lessen your guilt. Withholding this type of evidence violates your constitutional rights under the landmark Brady v. Maryland decision.

WHAT EVIDENCE MUST THE DEFENSE SHARE?

Discovery goes both ways. While the prosecution’s obligations are greater, the defense must also share certain materials if they intend to use them at trial, such as:

Expert witness reports
Alibi witnesses
Physical evidence collected by the defense

This allows both sides to evaluate the evidence fairly before trial.

WHY DISCOVERY IS SO CRITICAL IN A CRIMINAL CASE

Discovery often determines the direction of a criminal case. It can reveal:

Weaknesses in the prosecution’s evidence (for example, unreliable witnesses or missing footage).
Opportunities for dismissal if your rights were violated during arrest or evidence collection.
Grounds for plea negotiations, such as reducing charges or penalties.

A skilled Missouri defense attorney knows how to analyze every piece of discovery material to identify inconsistencies, errors, or constitutional violations that could help your case.

Delays and Discovery Problems: In some cases, prosecutors fail to turn over evidence on time or provide incomplete information. This can lead to serious problems, including:

Surprise witnesses appearing at trial,
Missing videos or reports,
Late-discovered forensic evidence, or
Police misconduct being hidden.

Your attorney can file motions to compel discovery — legal requests that force the prosecution to produce evidence. If the prosecution fails to comply, a judge can impose penalties, exclude evidence, or even dismiss the case.

HOW DISCOVERY HELPS BUILD YOUR DEFENSE

An experienced Kansas City criminal defense lawyer uses the discovery process to:

Scrutinize police reports for inconsistencies or errors.
Compare witness statements to find contradictions.
Examine forensic testing for mistakes or unreliable results.
Identify constitutional violations such as illegal searches or coerced confessions.
Negotiate with prosecutors using weaknesses in their evidence.

Many criminal cases are won — or lost — based on what’s uncovered during discovery.

COMMON EXAMPLES IN MISSOURI CASES

DWI Cases: Discovery may reveal body-cam footage showing officers skipping required steps in sobriety testing.

Drug Charges: Chain-of-custody reports may show that evidence was mishandled or contaminated.

Assault or Domestic Violence: Witness statements may conflict or show signs of bias.

Theft or Fraud: Discovery can expose financial discrepancies or lack of proof.

In each example, careful analysis of discovery can lead to evidence being suppressed or charges reduced.

WHY YOU NEED AN EXPERIENCED KANSAS CITY CRIMINAL DEFENSE LAWYER

Trying to handle a criminal case without a lawyer means you won’t know what evidence the prosecution might have — or what they’re required to share. Discovery is governed by complex rules that only an experienced attorney knows how to navigate.

A defense lawyer can:

Demand all evidence you’re entitled to under Missouri law.
Identify missing or incomplete information.
File motions to suppress illegally obtained evidence.
Use discovery materials to craft the best defense strategy.

Discovery is the exchange of evidence between prosecution and defense. Missouri law requires prosecutors to share police reports, videos, witness statements, and exculpatory evidence.
