    What Makes a Crime in St. Louis, MO “Federal”?

    The Tenth Amendment of the U.S. Constitution reserves most criminal enforcement to individual states. Typically, charges like assault, theft, or DUI are prosecuted at the state level.

    However, certain offenses trigger federal authority — particularly when they cross state lines, involve federal agencies, or impact national interests.

    Your case may be prosecuted federally under the following conditions:

    • It violates a federal statute such as those involving drug trafficking, wire fraud, or weapons offenses.
    • It involves multiple states or influences economic activity between multiple jurisdictions.
    • It happens on federal property (like property controlled by the federal government, including VA hospitals or administrative buildings).
    • It targets the federal government, involving crimes against institutions like the IRS, federal courts, or elected officials.
    • It involves serious, complex, or national-level criminal activity such as terrorism, large-scale conspiracies, or organized financial fraud.

    Key takeaway:
    What makes a crime federal isn’t just who’s involved — it’s how the entire legal system changes around it. The federal legal process differs in rules, sentencing, and procedural structure from MO’s state court cases. That’s why working with a defense attorney experienced in the federal court system is essential.

    Common Federal Charges We Defend in St. Louis, MO

    The federal system handles an array of serious offenses — from large-scale fraud schemes to trafficking cases that span jurisdictions. Each charge carries its own risks, but all share one thing in common: the federal government brings massive resources to the table.

    Our St. Louis, MO-based federal defense team at Combs Waterkotte defends clients against a wide range of serious federal charges, such as:

    • Federal drug trafficking and distribution
      Involves producing, transporting, or distributing illegal drugs — often with interstate or international elements.
    • Federal wire fraud and federal mail fraud
      Involves schemes that use email, phones, or postal services to carry out fraud – frequently tied to corporate or financial misconduct.
    • Federal money laundering
      Involves structuring or layering financial activity to hide the unlawful origin of assets.
    • Federal tax evasion and financial crimes
      Occurs when individuals or businesses avoid paying federal taxes through deception or omission, often linked to broader fraud cases.
    • Federal weapons offenses
      Covers firearm possession, sale, or transport when linked to other crimes or restricted individuals.
    • Federal child exploitation and federal child pornography offenses
      These highly sensitive cases demand a thoughtful, tactful defense and often carry severe sentencing risks.
    • Federal cybercrimes
      Encompasses internet-based crimes that target individuals, businesses, or government systems across jurisdictions.
    • Federal public corruption and bribery
      Involves schemes to influence federal actions or decisions through illegal payments or favors.
    • Immigration-related offenses
      May involve unlawful entry, visa fraud, or providing aid to noncitizens in violation of federal immigration law.

    To compare:
    A theft case in state court may be resolved quickly by local authorities, but federal fraud charges can trigger complex investigations involving the FBI, expert analysts, and a grand jury. That difference in scale changes not just the risk, but how your defense must be built from day one.

    How the Federal Criminal Process Works in St. Louis, MO

    Federal criminal cases follow a very different path than their state counterparts. The process often begins long before a person is even arrested.

    Here’s what usually happens in a federal criminal case:

    Step 1: Investigation

    Federal investigations are often extensive and conducted in secret. Agencies like the FBI, DEA, or IRS may monitor bank accounts, intercept communications, or build a case over months – even years – before making an arrest.

    Most common mistake: Waiting until formal charges are filed to hire a federal crimes defense attorney in St. Louis, MO. Getting counsel early gives us more options to influence the outcome.

    Step 2: Indictment

    Prosecutors seeking to file formal charges bring the matter to a federal grand jury for review.

    An indictment signals that charges have been authorized, and for many, it’s the first sign they’re being targeted by the government.

    Step 3: Arraignment and Pretrial Motions

    The defendant is required to appear before a federal judge and enter a formal plea. This is the first opportunity for your federal defense lawyer in St. Louis, MO to weaken the government’s case and influence what happens next.

    In some cases, with pretrial investigation we can have the charges dismissed entirely.

    Step 4: Plea Negotiations or Trial

    Many federal cases end in a plea agreement, but not all. If your case goes to trial, we’ll build and present your defense before a federal judge and jury.

    This requires experience with federal rules of evidence, courtroom strategy, and trial advocacy.

    Step 5: Sentencing (if applicable)

    Federal judges rely on detailed sentencing rules set by the Guidelines, considering both the harm done and your record.

    Certain offenses come with non-negotiable minimum prison sentences.

    Step 6: Appeals (if applicable)

    If convicted, you may be able to appeal — but the process demands precision and thorough knowledge of federal appellate rules.

    In summary:
    The federal system is fast-moving and unforgiving in its structure. Federal agents and prosecutors have a head start — your defense should be just as prepared.

    How Our St. Louis, MO Federal Criminal Defense Lawyer Approach Federal Cases

    Defending a federal case requires more than just legal knowledge – it demands strategy, timing, and the ability to adapt to a system where the odds are stacked in the government’s favor.

    Our approach is built around early intervention, thorough investigation, and focused and aggressive client-centered advocacy.

    Step 1: Early Intervention

    Don’t wait until it’s too late — the right time to get legal help is before you’re formally charged. A target letter, subpoena, or visit from federal authorities usually means the government is preparing to charge you.

    Our role starts with direct communication with the prosecution, asserting your rights, and helping shape the case before charges are finalized.

    Step 2: Strategic Investigation

    We don’t wait for prosecutors to define the facts. We collaborate with private investigators, forensic analysts, and expert witnesses to find what the prosecution missed — and use it to your advantage.

    Step 3: Realistic Negotiation

    In many cases where the state’s evidence is strong, especially where mandatory minimums apply, negotiating a smart plea deal is key to avoiding disastrous outcomes.

    We know how to navigate plea discussions while preserving leverage, and we always prepare for trial – whether we expect to go to one or not.

    You’ll get the facts, the risks, and the strategy — but the choice is always yours.

    Step 4: Trial Readiness

    If your case proceeds to trial, you’ll be represented by attorneys with real courtroom experience and federal trial wins. Our strategy focuses on clarity, credibility, and powerful storytelling that resonates with federal juries.

    Step 5: Sentencing Advocacy

    If your case results in a conviction, our work isn’t over. Our team crafts persuasive sentencing arguments, emphasizing mitigating circumstances to secure the lowest sentence possible under — or outside — the Federal Sentencing Guidelines.
