FBI Investigations

Federal Criminal Defense: FBI Investigations

The investigation does not begin with an arrest. In most federal cases involving the FBI, the arrest is one of the last things that happens. The work that precedes it—grand jury subpoenas, witness interviews, document production, surveillance, and the assembly of a case file that may run to tens of thousands of pages—takes months or years, and during that time the subject of the investigation may have no idea it is occurring. The first indication is often something small: a phone call from a business associate who has been contacted by an agent, or the appearance of a grand jury subpoena directed to a bank or an accountant. By the time the subject perceives the investigation, the government has already built most of its case.

That asymmetry defines the problem. The government operates on its own timeline, gathers evidence without constraint of an adversary, and presents its conclusions to a grand jury that hears only one side. The defense, when it begins, starts from behind. How far behind depends on when the subject retained counsel and what was done—or not done—in the interval between the first signal and the first conversation with a lawyer.

The Statutory Landscape

Federal criminal law does not operate the way most business owners expect. The statutes the FBI relies on in white-collar investigations are broad, overlapping, and designed to give prosecutors flexibility in selecting charges that fit the conduct. A single course of business activity can be charged under multiple theories, each carrying its own penalty range, and the government’s decision about which statutes to invoke is often a function of strategy rather than the nature of the offense.

The mail and wire fraud statutes, 18 U.S.C. §§ 1341 and 1343, are the foundation of most federal white-collar prosecutions. They require proof that the defendant devised a scheme to defraud and used the mails or interstate wires in furtherance of it. The wire fraud statute in particular has become the government’s preferred instrument because nearly every commercial transaction now involves an electronic communication. Each email, each wire transfer, each electronic filing constitutes a separate count, and each count carries a maximum of twenty years.

Section 1001 of Title 18 criminalizes false statements made to a federal agent or agency. It does not require that the statement be made under oath. An interview with an FBI agent in which the subject provides inaccurate information—even if the subject does not realize the inaccuracy rises to the level of materiality—can become an independent charge carrying up to five years. The statute is the reason experienced defense counsel rarely permit a client to speak with federal agents without preparation, and sometimes not at all.

The obstruction statutes occupy their own category. Section 1519 criminalizes the destruction, alteration, or concealment of documents with intent to impede a federal investigation. Section 1512 reaches further, covering witness tampering and the corrupt persuasion of another person to withhold testimony or destroy evidence. These statutes carry penalties of up to twenty years. They are not secondary charges. In practice, obstruction counts are sometimes the strongest part of the government’s case, because the conduct that constitutes obstruction—deleting emails, asking a colleague to change a story, shredding records after receiving a subpoena—tends to produce evidence that a jury finds more intuitive than the underlying fraud.

How the Investigation Develops

FBI investigations follow a procedural sequence that is worth understanding because each stage carries different risks and different opportunities for the defense. The government classifies the subjects of its investigation in three categories: witness, subject, and target. A witness is someone the government believes has information but is not suspected of wrongdoing. A subject is someone whose conduct falls within the scope of the investigation. A target is someone the government has substantial evidence to believe has committed a crime. These classifications are not disclosed automatically, and the government is not required to inform someone that their status has changed.

The classification matters because it determines the strategic options available to the defense. A witness can cooperate freely. A subject must make a calculation about whether cooperation will resolve the matter or provide the government with additional evidence. A target is, in almost every case, facing charges, and the question is whether to negotiate a resolution or prepare for trial. The problem is that the subject often does not know which category applies, and the government’s willingness to say is inconsistent.

Grand jury subpoenas are the primary tool. They compel the production of documents and testimony, and they operate under rules that favor the government: the target has no right to be present, no right to present evidence, and no right to cross-examine witnesses. The grand jury’s role is to determine whether probable cause exists, and the practical threshold for an indictment is low. The observation that a grand jury would indict a ham sandwich is overstated, but the structural advantages are real.

Search warrants represent an escalation. When the FBI executes a search warrant at a business or residence, it means a federal magistrate has found probable cause to believe that evidence of a crime will be found at that location. The warrant itself is based on an affidavit that, at the time of execution, is sealed. The defense does not know what the agent told the magistrate. The scope of the warrant defines what the agents may seize, but in practice, digital devices and entire file servers are often taken under broad language authorizing the seizure of electronically stored information. Privilege issues become urgent and immediate.

What happens in the first forty-eight hours after a search warrant execution often determines the trajectory of the case. Whether a privilege review protocol is established, whether the government’s filter team is challenged, whether the client’s employees are instructed on their rights—these are decisions that cannot wait.

The False Statements Problem

Section 1001 deserves separate treatment because it creates a risk that most people do not appreciate until it is too late. When two FBI agents arrive at a place of business and ask to speak with the owner, the natural response is to cooperate. The conversation feels informal. No Miranda warnings are given because the subject is not in custody. The agents are polite and conversational. They may not even identify the specific matter under investigation. But they are recording the interview in their notes—a written summary called a 302—and any material misstatement in that conversation is a federal crime, whether or not the subject knew the statement was material and whether or not the subject was trying to deceive.

The asymmetry is severe. The agents already know the answers to many of the questions they are asking. The purpose of the interview is not primarily to gather information; it is to lock the subject into a version of events that the government can later compare against the documentary record. A subject who understates revenue, mischaracterizes a relationship with a business partner, or provides a timeline that conflicts with email records has created a separate criminal exposure that exists independent of whatever conduct the agents were originally investigating.

We have represented clients whose primary legal exposure arose not from the underlying business conduct but from statements made during an initial interview that no lawyer was present for. The underlying matter might have been resolved administratively. The false statement could not.

Cooperation, Proffers, and the Decision That Defines the Case

At some point in most federal investigations, the government extends an offer: cooperate, and we will consider it at sentencing. The offer arrives through a proffer agreement, sometimes called a “queen for a day” letter, under which the subject agrees to meet with prosecutors and agents and provide a full account of their knowledge of the relevant conduct. In exchange, the government agrees not to use the subject’s own statements against them in its case-in-chief, with significant exceptions.

The exceptions are where the risk lives. If the subject makes a false statement during the proffer, the agreement is voided and the statements become admissible. If the subject’s statements are inconsistent with testimony given at trial, the government may use the proffer statements for impeachment. And the derivative use question—whether the government can use leads obtained from the proffer to develop independent evidence—is governed by the specific language of the agreement and varies by circuit. The proffer is not a safe harbor. It is a negotiated exchange with terms that must be understood before the client walks into the room.

The decision to cooperate or not cooperate is the most consequential strategic choice in most federal cases, and it must be made with imperfect information. Cooperation can result in a substantially reduced sentence, the possibility of a 5K1.1 motion from the government, and in some cases the declination of charges entirely. But cooperation requires the subject to provide truthful, complete information about their own conduct and the conduct of others, and once that process begins, it cannot be undone. A client who cooperates and later decides to go to trial has already provided the government with a detailed account of the facts.

I do not have a default recommendation on cooperation. The decision depends on the strength of the government’s evidence, the client’s exposure, the quality of the potential defense at trial, and the client’s personal circumstances. What I do insist on is that the decision be made after a thorough review of the evidence and a realistic assessment of the likely outcomes at trial, not out of panic in the week after a search warrant.

Document Preservation and the Obstruction Risk

The moment a business or individual becomes aware of a federal investigation—or reasonably should become aware—a document preservation obligation attaches. The obligation is not created by statute alone; it arises from the combination of the obstruction statutes and the practical reality that document destruction after notice of an investigation is among the easiest facts for a prosecutor to present to a jury.

The scope of the obligation is broader than most clients expect. It extends to electronically stored information, including text messages, messaging applications, cloud storage, and metadata. It reaches documents that the client might consider irrelevant. The standard is not whether the document is important but whether a reasonable person would understand that it might be relevant to the investigation. Auto-delete settings on messaging platforms, routine document destruction policies, and the migration of data between systems all create risks when an investigation is pending or reasonably anticipated.

We issue a litigation hold in the first days of any engagement involving a federal investigation. The hold is specific, it is documented, and it is communicated to every person within the organization who may possess relevant information. The hold itself becomes evidence that the client took the obligation seriously, and its absence becomes evidence of the opposite.

The Quiet Part

Most people who contact this firm about an FBI investigation are not calling at the optimal moment. They are calling because something has happened—a subpoena, a search warrant, a call from a co-worker—that has made the situation impossible to ignore. The weeks or months between the first warning sign and that call are the period in which the most damage is typically done: statements made without counsel, documents handled carelessly, strategic options foreclosed by action or inaction.

The federal criminal system is not forgiving of delay, and it is not structured to give the defense a second chance at decisions that were made under pressure. The government has resources, time, and institutional patience. The defense has preparation, judgment, and the ability to act before the government’s theory hardens into charges.

If you are aware of a federal investigation that involves you or your business, the single most valuable step is a conversation with counsel who handles these matters regularly. That conversation is privileged, it costs nothing, and it is the point at which the available options become visible.
