Most federal investigations are already months deep before anyone knocks on a door. There’s no announcement, no formal notice, and no moment where an agent calls to say you’re being looked at. By the time a federal agent makes direct contact, the government has often already reviewed financial records, interviewed associates, and presented evidence to a grand jury. The assumption that silence or polite cooperation will make the situation go away is one of the most dangerous ideas a person can carry into that first conversation.
We represent people at every stage of the federal criminal process, from the earliest signs of scrutiny through trial. Attorney Jed Silverman is Board Certified in Criminal Law by the Texas Board of Legal Specialization, a distinction held by fewer than 10% of Texas criminal defense attorneys, and he’s licensed to practice in the Southern, Eastern, and Western Districts of Texas, the 5th Circuit Court of Appeals, and the U.S. Supreme Court. That range of access matters because federal cases don’t always stay in one district. What matters most, though, is this: the decisions made before any indictment are often the ones that determine how a case ends.
How Federal Investigations Begin & Why You May Not Know
Federal agencies build cases quietly and thoroughly. The FBI, DEA, ATF, IRS Criminal Investigation Division, and Homeland Security Investigations all have the resources to conduct investigations that run for a year or longer without the target knowing. That’s not an exaggeration. It’s the structure of how federal cases are assembled.
Investigations are triggered by a range of sources: whistleblower complaints, Suspicious Activity Reports that financial institutions are required to file under the Bank Secrecy Act, tips from confidential informants, referrals from state law enforcement, and pattern detection by agencies like IRS Criminal Investigation. The Southern District of Texas is one of the busiest federal districts in the country. Drug trafficking, healthcare fraud, wire fraud, tax evasion, and public corruption cases are all common here. If your business, finances, or associates touch any of those areas, the investigative machinery can begin moving without any visible sign.
The Tools Federal Investigators Use to Build Their Case
Federal investigators don’t rely on a single technique. By the time a case reaches the indictment stage, prosecutors have typically layered multiple methods to assemble their evidence.
Grand Jury Subpoenas
A grand jury subpoena compels the production of documents, bank records, emails, and business records, or requires sworn testimony before the grand jury itself. These aren’t optional. Ignoring or improperly responding to one can result in contempt charges. If you or your business receives a grand jury subpoena, it’s a clear signal that an investigation is underway.
Search Warrants & Wiretaps
Federal search warrants can cover homes, offices, vehicles, and electronic devices. Real-time interception of phone calls and electronic communications is authorized under Title III of the Omnibus Crime Control and Safe Streets Act and requires a separate court order. In drug trafficking and organized crime investigations, Title III wiretaps are used routinely.
Confidential Informants
The person recording a conversation at the direction of federal agents might be someone you trust. In drug trafficking and financial crime investigations, informants are frequently people who know the target well: business associates, employees, or longtime acquaintances cooperating under their own legal pressure. The conversation you have over lunch can become government evidence.
Warning Signs You Are Under Federal Investigation
Federal agents often make contact with the edges of a target’s life before approaching the target directly. Recognizing these signs early is critical.
- Agents contacting your associates: If federal agents have approached your family members, employees, or business partners to ask questions about you or your activities, you’re almost certainly at least a subject of an active investigation.
- A target letter from the U.S. Attorney’s Office: This letter tells you directly that prosecutors believe they have substantial evidence and are weighing indictment. It may include an invitation to testify before the grand jury or to cooperate. It should never be responded to without defense counsel.
- An associate’s arrest in the same area of activity: When someone in your professional or personal circle is arrested on federal charges connected to work or conduct you shared, prosecutors are typically seeking cooperation agreements that point to others. That includes you.
Target, Subject, or Witness: What Your Status Means & Why It Can Change
The Department of Justice classifies participants in an investigation into three categories: target, subject, and witness. Understanding the difference matters because many people make serious mistakes based on a false sense of security about where they stand.
A target is someone against whom the government believes it has substantial evidence of criminal involvement, and indictment is considered likely. A subject is someone whose conduct falls within the scope of the investigation but whose status hasn’t been resolved. A witness has information relevant to the investigation but isn’t currently suspected of wrongdoing.
These designations are fluid. A subject becomes a target as evidence accumulates. More critically, a witness who makes a false statement to federal investigators can instantly become a target under 18 U.S.C. § 1001, a federal statute that makes it a felony to knowingly provide a materially false statement to a federal agent, even in a casual, unsworn conversation. No oath is required, and the false statement doesn’t have to concern the central crime; it just has to be material, meaning relevant to something the government is investigating. Federal agents are also legally permitted to use deception during interviews, including misrepresenting what evidence they already have. Any unrepresented conversation with federal agents carries legal risk regardless of whether you’ve done anything wrong.
Why the Pre-Indictment Window Is Your Most Important Opportunity
Once a case is indicted and proceedings begin at the Bob Casey United States Courthouse in Houston, the defense moves into a structured, public process. Hearings, scheduling orders, and the formal machinery of the Southern District take over. The flexibility that existed before indictment is largely gone.
The pre-indictment phase is when we can communicate directly with the assigned Assistant U.S. Attorney to assess the scope of evidence, present exculpatory facts, and sometimes make the case for declining charges entirely. Asset forfeiture can also be addressed before formal proceedings lock in the government’s position. Pre-indictment resolutions, when they happen, typically carry more favorable treatment under the Federal Sentencing Guidelines than agreements reached after charges are filed. This window is real, but it closes. Prosecutors don’t wait while someone decides whether to retain counsel, and once an indictment is returned, the options that existed before it no longer do.
What to Do If You Believe You Are Under Federal Investigation
Three things matter most, and the order matters too.
Invoke Your Fifth Amendment Right to Remain Silent
If a federal agent contacts you, politely tell them you won’t answer questions without your attorney present and say so explicitly. Then stop talking. Simply going quiet without invoking your right isn’t enough: under the Supreme Court’s ruling in Salinas v. Texas, pre-custodial silence that isn’t expressly invoked can be used against you at trial. A clear, verbal invocation is what creates the protection.
Preserve All Documents & Communications
Don’t delete emails, destroy records, or alter any documents once you have reason to believe an investigation is underway. Obstruction of justice and evidence tampering are standalone federal charges that can be added to whatever the original investigation concerned. Preservation applies to digital files, physical records, financial documents, and communications of every kind.
Retain Federal Defense Counsel Before You Need It
The strongest position in a federal investigation is one where defense counsel is already at the table before an indictment arrives. A member of our team has more than 20 years of experience working within the Texas prison system, which gives us real perspective on what a federal conviction means beyond the courtroom. That understanding sharpens every argument we make for early intervention, because we know what’s actually at stake when federal charges go unanswered.
The Investigation Stage Is Where Federal Cases Are Often Decided
Courtrooms get attention. Verdicts get reported. But in federal criminal cases, the investigation stage is frequently where the trajectory of a case is set. The conversations that happen before a charge is filed, the records that get produced or protected, the decisions made about whether and how to engage, all of it shapes what a case looks like by the time it reaches a federal courtroom.
If you have reason to believe you’re under investigation, the time to act is now, not after a target letter arrives.
