Federal charges are a different category of serious. The resources behind a federal prosecution are significantly greater than what you’ll find at the state level: FBI agents, federal prosecutors who handle only criminal cases, and a sentencing guidelines system that removes much of the flexibility a state court judge might otherwise have. A federal conviction can mean years in prison with no possibility of parole.
Just Criminal Law defends clients facing federal criminal charges in the U.S. District Court for the District of Wyoming, with divisions in Casper and Cheyenne. Christina L. Williams spent years as a prosecutor before founding the firm. She understands how federal investigations develop, how the U.S. Attorney’s office builds its cases, and where the defense has room to challenge the government’s evidence and strategy.
Federal vs. State Criminal Charges: What Changes
State charges and federal charges aren’t the same thing, even when the underlying conduct looks similar. Federal jurisdiction typically applies when the offense crosses state lines, involves federal property or federal employees, is specifically designated as a federal crime (like certain firearms and fraud offenses), or involves conduct that federal agencies have jurisdiction over by statute.
The most immediate practical difference: federal sentencing is governed by the United States Sentencing Guidelines, a structured system that calculates a recommended sentencing range based on the offense level and the defendant’s criminal history. Judges have some discretion, but mandatory minimums apply to certain offenses and can take that discretion away entirely. A federal drug trafficking conviction involving specific quantities can trigger sentences measured in decades, not years.
Federal prosecutors are also different in how they work. They typically don’t file charges until the investigation is largely complete. By the time an indictment comes, the government has already built its case. That’s why it’s critical to have defense counsel involved as early as possible, including during the investigation phase if you’re under federal scrutiny before charges are filed.
Federal Criminal Charges We Defend in Wyoming
Federal Drug Crimes
Federal drug charges involve trafficking, distribution, conspiracy to distribute, and manufacturing of controlled substances. Federal quantity thresholds trigger mandatory minimum sentences that can be severe. Drug cases that cross state lines or involve large-scale distribution networks are typically prosecuted federally rather than at the state level.
Wire Fraud and Mail Fraud
Using electronic communications or the U.S. mail in furtherance of a scheme to defraud is a federal offense. Wire fraud charges are common in white-collar prosecutions and can apply to a wide range of conduct involving misrepresentation for financial gain. Each individual communication can be charged as a separate count.
Federal Conspiracy Charges
Federal conspiracy law is broad. You can be charged with conspiracy if the government believes you agreed with one or more people to commit a federal offense, even if the underlying offense was never completed. Conspiracy charges are frequently added to other federal charges and significantly expand potential sentencing exposure.
Federal Firearms Charges
Felon in possession of a firearm, using a firearm in furtherance of a drug trafficking crime, and illegal sale or transfer of firearms are all federal charges with mandatory minimum sentences. Weapon offense charges are often added alongside other offenses to increase sentencing leverage.
White Collar and Financial Crimes
Embezzlement, money laundering, bank fraud, securities fraud, and identity theft are frequently prosecuted at the federal level, especially when they involve financial institutions, federal programs, or large amounts of money. These cases are document-intensive and require an attorney experienced in reviewing financial evidence.
Federal Sex Crimes
Child pornography, sex trafficking, and certain internet-related offenses are prosecuted federally under statutes that carry severe mandatory minimums. Sex crime cases require immediate defense intervention and careful handling of digital evidence.
Federal Courts in Wyoming
The U.S. District Court for the District of Wyoming handles all federal criminal cases in the state. The court has two primary locations: the James F. Barrett U.S. Courthouse at 2120 Capitol Ave in Cheyenne, and the Joseph C. O’Mahoney Federal Center at 200 E. B St in Casper. Cases are assigned to these divisions based on where the alleged offense occurred.
Federal cases move on the government’s timeline. Grand jury proceedings, which happen before an indictment is returned, are not public, and you may not know you’re under investigation until charges are filed. If you’ve received a target letter from the U.S. Attorney’s office, been contacted by federal agents, or believe you may be under federal investigation, that’s the time to call an attorney. Not after charges are filed.
Federal Sentencing Guidelines: What They Mean for Your Case
The Federal Sentencing Guidelines assign points based on the offense level (the seriousness of the crime and specific circumstances) and the defendant’s criminal history category. The resulting range is advisory but carries significant weight. Judges who depart from the guidelines must explain their reasoning, and departures can be appealed.
Some federal offenses carry mandatory minimums that override the guidelines entirely. Federal drug trafficking offenses tied to specific drug quantities have mandatory floors that even a sympathetic judge can’t go below without a cooperation agreement or specific safety valve provisions. Understanding your actual sentencing exposure from the beginning of the case shapes every decision that follows.
Cooperation with the government is a factor in many federal cases. Providing substantial assistance to prosecutors can lead to a downward departure in sentencing. But cooperation is a complicated decision with long-term consequences that should be carefully evaluated before any discussions with federal agents or prosecutors.
What a Former Prosecutor Brings to Your Federal Defense
Christina L. Williams built her career understanding how prosecutors think and how cases get built. At the federal level, that perspective is especially valuable. Federal investigations are thorough and methodical. The government doesn’t typically bring charges it doesn’t think it can win. That means the defense work has to be equally thorough.
Just Criminal Law approaches federal cases by examining the investigation itself: how evidence was gathered, whether constitutional protections were observed, what the government’s theory of the case actually requires them to prove, and where the weaknesses are. Federal cases often have more procedural leverage than state cases, and finding that leverage requires an attorney who knows what to look for.
