The Stages of a Federal Investigation: A Timeline From Tip to Indictment
By the time you are under federal investigation, the government has usually built the case for a year or longer. Records have been pulled, and someone you know has already sat down with an agent. Federal white-collar cases are built to stay quiet until prosecutors are ready, and by then, much of the record has been set. Aaron L. Wiley, P.C., defends individuals and businesses under federal investigations in the Northern District of Texas. At the early stages, most clients never see it coming.
The Initial Tip or Complaint
Almost no white-collar case begins with an agent witnessing a crime in progress. It usually begins with information being handed to the government by someone else, such as:
A former employee who has left on bad terms and has knowledge of which files are important.
A bank compliance officer who files a suspicious activity report after noticing a series of unusual transactions.
A competitor’s complaint to a regulatory agency.
Data analytics. Federal agencies continuously run claims and billing data, and a provider whose numbers differ from the norm for their industry can be flagged, even if no one has complained about them.
Qui tam relators filing a False Claims Act lawsuit under seal, which may remain sealed for years as the government quietly investigates.
A tip is not a case. Most of them die quickly. The ones that survive tend to have documents behind them, and these documents are what federal prosecutors use to build their cases.
Preliminary Investigation and Evidence Gathering
An agent’s first job is to decide whether a tip justifies the agency’s time. This work happens entirely behind the scenes. Agents collect corporate filings, license records, property records, previous complaints, and public information. They may return to the source for a second, more detailed conversation. None of this requires you to be notified.
This stage often lasts for several months. It also determines something that is important later: whether the case goes to a prosecutor as a criminal referral or remains with a regulator as a civil or administrative issue.
Formal Federal Investigation
Once an Assistant U.S. Attorney accepts a referral, the process changes. Grand jury subpoenas are issued for documents, search warrants are supported by sealed affidavits, administrative subpoenas come from agencies like the HHS-OIG and the DEA, and IRS summons are issued for financial records. Cooperative witnesses have exposure and a reason to talk about the case.
Which agency leads depends on the alleged conduct. The FBI handles wire and mail fraud, the IRS-Criminal Investigation handles tax and money laundering, and the HHS-OIG works on healthcare matters alongside the FBI and state Medicaid fraud units. Many cases run both criminal and civil tracks simultaneously, and what happens on one side often moves to the other.
Time is on the government’s side here. The general federal statute of limitations gives prosecutors five years from the last alleged act, and bank fraud extends that to ten years.
Interviews, Subpoenas, and Target Letters
The Justice Department sorts people into three categories. Knowing which one applies to you changes everything about what happens next. A witness has information, but no real exposure. A person engaged in conduct within the scope of an investigation is a subject. A target is someone the prosecutors believe has substantial evidence linking them to a crime. These labels are not permanent. Witnesses can become subjects, and subjects can become targets.
Agents often make contact without warning, either at your home in the early morning or at your office in front of colleagues. The visit is not a coincidence of scheduling. It is intended to catch you before you can consult, and you are not required to say anything. Lying to a federal agent is a felony under 18 U.S.C. §1001. No oath, record, or transcript is needed for this charge to stick. People who have never committed a crime have been convicted based on what they said on a driveway.
A target letter is the formal version of the same message. It informs you that you are under investigation by a grand jury and invites you to respond, sometimes via a proffer conducted under a limited use agreement. A proffer may be valuable, but it can also be the worst decision in a case. No conversation should take place without a lawyer present who has read the agreement and can explain exactly what it covers.
Grand Jury Review
A federal grand jury consists of between 16 and 23 citizens, of which 12 must vote to indict. The standard is probable cause, not proof beyond reasonable doubt. No judge presides, and no defense lawyer is allowed in the room.
That is a lopsided process, and it is meant to be a screen rather than a trial. The real decision is not made by the grand jury. It is made by the prosecutor, who decides what to present. That is why the weeks leading up to a vote are so important. A written submission, a meeting with a line prosecutor, and a forensic accountant reading over the same transactions that the government has been looking at for a year – that is the last chance for the case to end without charges.
Indictment or Other Resolution
When the grand jury returns a true bill, the indictment may be sealed until agents are ready to arrest, or it may be issued with a summons directing you to appear. Arraignment follows within days. After that, comes the long middle part of a federal case: discovery disputes, suppression motions, and challenges to whether the charges constitute an offense at all.
Not every investigation ends there. Prosecutors decline cases. Matters are resolved civilly with the regulator instead. A deferred prosecution agreement means that charges are filed, but they are held in abeyance until conditions are met. A non-prosecution agreement means the matter is resolved without any charges being filed. Some defendants waive an indictment and plead guilty to a criminal charge that has been negotiated in advance.
Fewer than one in twenty white-collar indictments reaches a jury. This statistic is not an argument against trials. It is an argument about timing, as the decisions that shape the outcome are often made before an indictment is issued.
What Should You Do If You Learn You’re Under Federal Investigation?
Issue a litigation hold immediately and stop automatic email deletion. Preserve financial records and internal messages and documents that you have done so. Prosecutors will look closely at what happened to records after someone became aware of an investigation, and gaps in the record can turn a fraud case into an obstruction case.
Do not say anything to agents other than confirming your name and requesting their card. Do not call other people who have received subpoenas to compare recollections, as that call could be considered witness tampering.
If this is a corporate matter, understand that the company’s counsel represents the company and not you. Their loyalty is to the entity and what you say to them may not be privileged as it would be with you.
Bring defense counsel in now, not after charges are filed. Almost everything that is worth doing has a deadline attached to the pre-indictment phase.
Why Clients Choose Aaron L. Wiley, P.C.
Knowing how the government builds a case is different from reading about it. Aaron L. Wiley has sat in meetings where charging decisions are made, watched agents weigh conflicting witness accounts, and seen which evidence actually moves a jury versus which evidence only looks impressive in a press release. This perspective shapes how our firm approaches discovery, how we frame negotiations, and where we spend effort during an investigation that has not yet produced charges.
It also means fewer surprises. We generally know what the government’s next move will look like before it happens.

FAQs
Months and multi-year investigations are common at a minimum. Prosecutors usually have five years from the last alleged incident, or longer for some offenses. They often use this time to conduct investigations.
Not necessarily. Subpoenas can be issued to witnesses, defendants, and targets. The document itself does not always indicate which category you fall into, and it is a matter that your lawyer should discuss with the prosecutor.
You can, but you should not. Agents are trained interviewers, and the interview is not under oath. False or inconsistent statements made during an interview can be charged under Section 1001 even if the conduct was legal.
It notifies you that prosecutors are considering you a potential defendant in a grand jury investigation. This is also an opportunity, because charges have not been filed yet. Call a lawyer as soon as you receive this notification.
Sometimes, declinations, civil resolutions, and deferred or non-prosecution agreements can be real outcomes. Each one of these depends on lawyers getting involved, while prosecutors still have the discretion to exercise their powers.
You are arrested or summoned to appear, charged within days, and released on bail in most white-collar cases. Then the case proceeds to pre-trial motions, which usually last for months.
