Got a Target Letter in a Fraud Investigation? What to Do

Target vs. Subject vs. Witness: What Do These Words Actually Mean?

If a letter arrived with a prosecutor’s letterhead using the word “target,” or a detective left a voicemail asking you to “come in and chat” about a business deal, a transaction, or a client’s money, you are not imagining the seriousness of it. Both are the visible tip of an investigation that has usually been running quietly for weeks — subpoenaed bank records, interviews with your coworkers or clients, sometimes a grand jury already reviewing evidence — before you were ever contacted. The investigators already have a working theory. What you say next either confirms it or gives your attorney room to challenge it.

This article walks through exactly what a target letter or investigator contact means, the difference between being a target, a subject, and a witness, and the concrete steps — and missteps — that decide whether this stays an investigation or becomes an indictment. For the fuller picture of how we defend fraud and financial-crime allegations, see our Scottsdale white collar crimes practice page, and if a detective has already reached out, read our guide on what to do when police want to question you in Scottsdale.

Prosecutors and federal agencies use three specific labels for people connected to a criminal investigation, and the label you are given tells you almost everything about how much danger you are in.

• Witness. Someone believed to have relevant information but who is not suspected of committing a crime. Witnesses can still be compelled to testify, and their answers can end up hurting someone else — or, if their story shifts, themselves.
• Subject. Someone whose conduct is within the scope of the investigation and who might be involved, but prosecutors have not yet decided whether they have enough to charge. This is the murkiest category — a subject can become a target or can be cleared, depending on what the investigation turns up next.
• Target. Someone prosecutors have substantial evidence linking to a crime and are actively building a case to indict. A target letter is a formal, deliberate step — it is not sent casually, and it is often the last communication you get before a grand jury votes on charges.

A detective’s phone call rarely uses any of these words out loud. That does not mean the label does not apply to you — it usually means no one has told you yet. Part of what a defense attorney does immediately is find out, through contact with the detective, the assigned prosecutor, or the U.S. Attorney’s Office, exactly where you actually stand.

A Detective Called About a Fraud Investigation. What Do I Do Right Now?

Stop and do four things, in this order, before you do anything else:

• Do not call back yourself. Do not return the voicemail, do not agree to “just stop by,” and do not answer follow-up questions over text or email.
• Write down exactly what was said. The detective’s name, agency, badge or case number, phone number, and the exact words used (especially anything about “target,” “subject,” or a specific transaction).
• Do not touch records related to the transaction. Do not delete emails, shred documents, wipe a phone, close an account, or ask anyone else to do so — even documents you believe are unrelated or unhelpful to you.
• Call a criminal defense attorney the same day. Your attorney contacts the detective or prosecutor directly, learns what they are willing to say about the investigation’s status, and controls every future point of contact.

The same rules apply whether the contact was a phone call, a knock at your door, a subpoena to your business, or a target letter in the mail. The format is different; the correct response is not.

Why This Signals a Pre-Charge, Often Grand Jury, Investigation

Both a target letter and a detective’s outreach almost always mean charges have not been filed yet — but the machinery to file them is already running. Arizona felony fraud cases, and federal fraud cases, are frequently built toward a grand jury: under Arizona law, a grand jury is a body of citizens impaneled by the Superior Court and sworn to inquire into public offenses, hear evidence presented by a prosecutor, and vote on whether to issue an indictment. Federal white-collar cases move the same way in front of a federal grand jury convened by the U.S. Attorney’s Office. Neither process requires you, or your attorney, to be present or to cross-examine witnesses — which is exactly why the pre-indictment period, while you still have a voice, matters so much.

A target letter is one of the clearest outward signs that a grand jury presentation may already be scheduled or underway. It typically explains the general nature of the investigation, may invite you to testify or provide a statement, and sometimes references your right to counsel. None of that is a courtesy you should navigate alone — it is a narrow, time-limited opportunity for a defense attorney to present exculpatory evidence, negotiate a proffer, or argue against charges before an indictment ever becomes public.

What Arizona Fraud Charges Could Follow a Target Letter?

What you are ultimately investigated for depends entirely on the facts, but Arizona fraud investigations most often develop toward one or more of the following felony charges. Federal investigations run in parallel on separate, often more severe, federal statutes such as mail and wire fraud, which can carry penalties of up to 20 years in federal prison per count.

One of the most active fraud-investigation tracks in Arizona right now involves healthcare and AHCCCS billing fraud — the state’s sober living home crackdown has generated grand-jury target letters and subpoenas for providers, billers, and clinic operators under A.R.S. 13-2310 and related statutes. If your letter or detective call is tied to Medicaid or behavioral-health billing, that page breaks down the specific charges and defenses.

What NOT to Do After a Target Letter or Detective Call

The instinct to “just explain what really happened” is the single most common way people turn a winnable investigation into an indictment. Avoid every one of the following:

• Do not talk to investigators without a lawyer present — not on the phone, not “off the record,” not to “clear it up quickly.” There is no off-the-record conversation with a detective or federal agent; anything you say can be used, and agents are permitted to take notes that become the government’s version of what you said, right or wrong.
• Do not destroy, alter, or “clean up” records — emails, texts, spreadsheets, receipts, contracts, or devices. Under A.R.S. 13-2809, tampering with physical evidence when an official proceeding is pending or about to be instituted is a separate class 6 felony, on top of whatever the underlying investigation is about. It can also destroy evidence that would have helped you.
• Do not contact co-workers, clients, or business partners to “get the story straight.” Coordinating accounts, even innocently, can look like obstruction and can turn a cooperative witness into someone with a motive to protect themselves at your expense.
• Do not post about it, discuss it on recorded lines, or vent to anyone but your lawyer. Jail calls, voicemails, texts, and social media are all reviewed in fraud investigations far more often than people expect.
• Do not ignore the letter or the call and hope it goes away. Silence toward investigators is fine and often correct; silence toward your own defense is not. Every day without counsel is a day the government builds its case uncontested.

What TO Do: Proffers, Attorney-Managed Contact, and Preserving Evidence

The right response is not simply “say nothing forever” — it is putting a lawyer between you and the investigation so that any contact happens on your terms, not theirs.

Let your attorney make first contact

Once retained, we typically call the detective, agent, or prosecutor directly to learn the status of the investigation, what statutes are being considered, and whether an indictment is imminent. Investigators often tell a defense attorney more than they will ever tell you directly, because there is no risk of an unrepresented person making an admission on the call.

Consider a proffer — carefully, and only through counsel

In some cases, particularly where cooperation, a limited role, or genuine misunderstanding is part of the story, an attorney-negotiated proffer session lets you present your side under controlled, legally protected conditions, sometimes with negotiated limits on how the statements can be used. A proffer without that protection, or offered voluntarily before charges to “show good faith,” gives up the protection and gains nothing.

Preserve, don’t destroy, everything

The flip side of “do not destroy records” is affirmatively preserving them — back up devices, avoid auto-delete settings on email and messaging apps, and route any new document requests through your attorney rather than responding on your own.

Get ahead of the narrative

Where the facts support it, we gather financial records, correspondence, and witness statements early so we can present context — a legitimate business dispute, a bookkeeping error, a third party’s conduct — to the prosecutor or the grand jury’s audience before an indictment is voted, not after.

State vs. Federal: Where Could Your Case Be Charged?

Fraud investigations in the Scottsdale and greater Phoenix area can run through either system, and sometimes both look at the same conduct before deciding who takes it.

• State fraud investigations — run by local police departments, the Arizona Attorney General, or county investigators — are prosecuted by the Maricopa County Attorney in Maricopa County Superior Court under statutes like A.R.S. 13-2310, 13-2002, and 13-2008.
• Federal fraud investigations — run by the FBI, IRS Criminal Investigation, Secret Service, postal inspectors, or other federal agencies — are prosecuted by the U.S. Attorney’s Office before a federal grand jury, often under mail fraud, wire fraud, bank fraud, or conspiracy statutes, and generally carry longer potential sentences.

A target letter on federal letterhead, or a visit from agents who identify a federal agency rather than a local police department, is a strong sign your matter is being built as a federal case, which changes both the stakes and the strategy substantially. Determining which system — or both — is actually involved is one of the first things your attorney should establish.

The Window to Get Ahead of Charges

The period between “someone is asking questions” and “an indictment is filed” is not a formality — it is frequently the single highest-leverage stretch of an entire criminal case. Once a grand jury returns an indictment, the case becomes public, an arrest or summons typically follows, and the options narrow considerably. Before that vote, a defense attorney can still:

• Contact the prosecutor to present mitigating facts, documentation, or an alternative explanation for a disputed transaction;
• Negotiate a proffer or limited-use cooperation agreement where it genuinely helps your position;
• Push back on overbroad characterizations of the conduct before they harden into charging language;
• In some cases, persuade a prosecutor that the matter is better resolved civilly, through restitution, or with lesser charges than what was originally being considered.

None of this is available to someone who talks to investigators alone, destroys records out of panic, or waits for an arrest before calling a lawyer. If you were recently contacted about your case status or booking, our guide to what happens after a Scottsdale arrest covers the next stage; the goal of everything in this article is to keep you from reaching that stage in a worse position than you have to.

How Tamou Law Group Defends Fraud Investigation Contacts

The moment you call us after a target letter or a detective’s outreach, we take over every point of contact with law enforcement. We reach out to the assigned detective, agent, or prosecutor to establish exactly what stage the investigation is at, whether a grand jury presentation is scheduled, and what statutes are being considered. We put every relevant record on legal hold so nothing you touch can later be characterized as evidence tampering, and we start gathering the documentation, witness accounts, and financial records that support your side before the government’s version becomes the only version.

Where it genuinely helps, we negotiate a carefully structured proffer or direct conversation with the prosecutor; where it does not, we make sure you never speak to investigators at all. Our team includes former prosecutors, law enforcement officers, and public defenders who have sat on every side of a fraud investigation and know how the Maricopa County Attorney’s Office and federal prosecutors evaluate pre-charge cases. Same-day consultations are available at our Scottsdale office near Camelback Road, or by phone if you cannot come in.
