An arrest by federal agents is life-changing. Whether you were taken into custody by the FBI, DEA, ATF, IRS Criminal Investigation, or Homeland Security, your case will be handled in the U.S. District Court for the District of Colorado, typically located at the Alfred A. Arraj Courthouse in Denver. From the moment of arrest, your case proceeds under the strict rules of the federal system—not state or municipal procedures.
At Perlman Defense Federal Criminal Lawyers, we represent clients in Colorado from the very first moment they are arrested through every stage of the federal process. The first major event is your initial appearance and detention hearing, which will determine whether you are released or remain in custody while your case proceeds.
Federal law requires that anyone arrested must be brought before a federal magistrate judge without unnecessary delay, usually within 48 hours of the arrest.
The initial appearance serves several key functions:
You will appear in court under custody of the U.S. Marshals Service.
You will be provided a copy of the complaint or indictment, which outlines the specific violations of federal law you are accused of committing. Common charges we see in Colorado include:
At this hearing, you do not enter a plea. That will occur later at the arraignment.
You have the constitutional right to be represented by legal counsel. If you cannot afford a private attorney, the court will appoint a federal public defender.
You are under no obligation to answer questions from federal agents or the court about the facts of your case. Anything you say can be used against you later.
If the government seeks to hold you without bond, you have the right to a detention hearing to determine if you should be released.
The detention hearing decides whether you will be:
In Colorado, detention hearings usually occur within 3 to 5 business days of the initial appearance if requested by your attorney.
The court considers two main factors under 18 U.S.C. § 3142:
The judge will evaluate whether you are likely to flee before trial. Factors include:
The government must show clear and convincing evidence that you pose a danger to others if released. This is common in cases involving:
If neither condition applies, you must be released under the Bail Reform Act.
The prosecutor files a motion asking the court to hold you without bail pending trial.
At Perlman Defense, we present evidence and arguments to show:
The magistrate judge may:
Even if you are released, the court can impose requirements such as:
Failure to comply with any condition may lead to immediate revocation of release and detention.
In Colorado, this is often at a facility like the Federal Detention Center (FDC) Englewood, near Denver.
You will be escorted by the U.S. Marshals Service for all future court appearances.
Being detained does not end your right to mount a defense. We visit clients in detention to prepare your case, file motions, and prepare for trial.
The first appearance and detention hearing are critical. Decisions made in these early stages can affect the entire course of your case. At Perlman Defense Federal Criminal Lawyers, we immediately:
Our experience appearing before federal judges in Colorado gives us insight into how to structure arguments that maximize the chance of pretrial release.
Do not make these errors. Contact legal counsel immediately after your arrest.
Yes, but only if the government proves by clear and convincing evidence that you are a flight risk or a danger to the community.
Only to answer routine administrative questions (name, age, etc.). You should never discuss the facts of your case at this stage.
Most federal detention hearings in Colorado last between 30 to 60 minutes, depending on the evidence presented.
Yes. You can file a motion to reopen the detention hearing or appeal the detention order to a federal district judge.
Your first appearance and detention hearing are some of the most important moments in your federal case. They set the tone for how prosecutors and judges view you and determine whether you will be able to prepare for trial from home or behind bars. The decisions made here can have long-term consequences on plea negotiations, trial preparation, and sentencing.
At Perlman Defense Federal Criminal Lawyers, we believe in aggressive early action. We know the local Colorado federal courts and understand what it takes to keep our clients out of pretrial detention.
