Received a Federal
Target Letter?

A target letter means the government has been building a case against you. The period between the letter and an indictment is when defense counsel has the most leverage.

Before you do anything else: Do not contact the U.S. Attorney's Office. Do not call the investigator. Do not speak to other subjects of the investigation. Retain federal defense counsel immediately.

What a Federal Target Letter Actually Means

A federal target letter is a letter from a United States Attorney's Office informing you that you are a target of a federal grand jury investigation. "Target" has a specific legal meaning: the government has substantial evidence linking you to a crime and you are a likely defendant in a future indictment.

The letter will typically identify the federal statutes you're suspected of violating, advise you that you have a right to remain silent, tell you that anything you say can be used against you, and invite you to testify before the grand jury — usually an invitation you should decline.

Receiving a target letter does not mean you've been charged. It means federal prosecutors believe they have enough to charge you, and they are either about to or want to give you a chance to cooperate before they do.

The Difference Between Target, Subject, and Witness

Federal prosecutors categorize individuals related to an investigation in three tiers:

Target — the government has substantial evidence linking you to a crime. You are the likely defendant.

Subject — your conduct is within the scope of the investigation, but you're not yet a target. This status can shift.

Witness — not currently suspected. But witnesses can become subjects or targets as investigations develop.

A letter saying "witness" or "subject" is not necessarily safer than one saying "target." If the government invites you to testify before a grand jury and you don't have counsel already, you need one before you respond to anything.

Do Not Contact the Government Without a Lawyer

The single most important thing to understand about a federal target letter is that it is not an invitation to explain yourself. It is notice that the federal government has been building a case against you, likely for months or years, and is now at a stage where they're ready to move.

Calling the Assistant U.S. Attorney whose number appears in the letter — to "explain what really happened," to cooperate proactively, or to find out what they know — is almost always a mistake made without counsel. Federal prosecutors are experienced interrogators. What you say will be documented, can be used against you, and can form the basis of additional charges (particularly false statements under 18 U.S.C. § 1001, which is a separate federal crime and does not require you to have been under oath).

The only call to make is to a federal criminal defense attorney.

Should You Testify Before the Grand Jury?

Almost always, no.

You have a Fifth Amendment right not to incriminate yourself before a grand jury. If you receive a subpoena to testify, that right applies — you can invoke it and refuse to answer questions that could incriminate you, even if the government doesn't like it.

Grand jury proceedings are secret. The government presents its witnesses and evidence without you or your attorney present. Jurors hear one side. The standard for an indictment (probable cause) is far lower than the standard for conviction (beyond a reasonable doubt).

Testifying gives the government a transcript of your words under oath, which can be compared to any prior statements you've made, any documents they have, and anything other witnesses say. Inconsistencies — even on collateral details, even innocent ones — become ammunition.

There are situations where proffer agreements and cooperation with federal investigators make sense, particularly early in an investigation when your cooperation has maximum value. But that decision should never be made without counsel who understands the specific investigation, the charges involved, and what the government likely already has.

What a Federal Defense Attorney Does Before Indictment

The pre-indictment period is often the most important phase of a federal case, and it's the phase most defendants don't know exists.

An experienced federal defense attorney will:

- Contact the AUSA handling the case to assess the state of the investigation - Attempt to determine what charges are contemplated and what evidence the government has gathered - Evaluate whether cooperation or proffer discussions make sense given the specific facts - Challenge unlawful searches, surveillance, or other constitutional violations before charges are filed - Negotiate — in some cases — a reduced or deferred charging agreement before indictment

Federal investigations move slowly, but federal prosecutors move decisively once they're ready to indict. The window between receiving a target letter and an indictment is the period where defense counsel has the most leverage and where the trajectory of a case can be meaningfully affected.

Federal Cases in the Northern District of Illinois

The Northern District of Illinois — prosecuted by the U.S. Attorney's Office for the Northern District of Illinois and investigated by agencies including the FBI, DEA, IRS-Criminal Investigation, and Homeland Security Investigations — is one of the most active federal prosecutorial districts in the country.

Federal practice is different from state court in ways that matter: - Separate admission to the federal bar is required (just being licensed in Illinois is not enough) - Federal sentencing is governed by the U.S. Sentencing Guidelines (USSG), which produce advisory sentencing ranges based on offense conduct and criminal history - Federal charges often carry mandatory minimum sentences with limited judicial discretion - Federal trials, discovery procedures, and motions practice follow separate rules (the Federal Rules of Criminal Procedure)
