A business card from a Tampa Police detective tucked into your door. A call from an FBI agent asking if you have a few minutes to talk. A grand jury subpoena with your name on it is arriving by certified mail. If one of these has happened to you or someone in your family, you are already inside what lawyers call a pre-indictment investigation, and the clock is running on decisions that will shape the rest of the case.
I have spent more than two decades in Hillsborough County criminal courts, first as a prosecutor with the 13th Judicial Circuit and now as a Board Certified criminal trial lawyer defending people in exactly this situation. The hardest truth I can share is this: the most important phase of a criminal case often happens before anyone is ever arrested. If you understand what is happening and move quickly, there is a real chance charges will never be filed.
What a Pre-Indictment Investigation Is
A pre-indictment investigation is the phase of a criminal case that takes place before formal charges are filed, while law enforcement and prosecutors decide whether they have enough evidence to bring a case against you. In the Florida state court, this is often called a pre-file investigation. In federal court, it is called a pre-indictment investigation because the government must present evidence to a federal grand jury to obtain an indictment.
The distinction matters. In Hillsborough County, an arrest by Tampa Police or the Sheriff’s Office does not mean you have been formally charged. Only the Hillsborough County State Attorney’s Office can do that by filing a document called an Information. Under Florida Statute § 907.04, if you are held in custody and no charges are filed within 21 days, you must be released. For felonies, the State generally has up to 175 days to file. That window, roughly four to six weeks in most cases, is when the prosecutor assigned to intake reviews the police report and decides whether the case moves forward.
In federal investigations run out of the Middle District of Florida, the timeline is longer and quieter. Federal agents can build a case for months or years before anyone sees a courtroom. You may first learn you are a subject when a target letter arrives from the U.S. Attorney’s Office, or when agents knock on your door asking for a conversation.
How People Learn They Are Under Investigation
Most clients who walk into my office at 2811 W. Kennedy Boulevard learned about the investigation in one of five ways. A detective called and asked them to come down to the station for a “quick chat.” Federal agents showed up at their home or office. A target letter arrived from the government. A grand jury subpoena appeared in the mail. A coworker or family member told them they had been interviewed about something.
Every one of those signals means the same thing: someone with a badge has already gathered enough information to think you may be involved in a crime. From my years on the prosecutor’s side, I can tell you that the detectives who called to ask for a friendly chat were not looking for your side of the story. They were hoping you would fill in the two or three gaps they needed to finish the case.
Why the Pre-Filing Window Matters More Than Almost Any Phase That Comes After
Once the State Attorney files an Information, the case has legal life. It exists in the court system. It shows up on background checks. Getting it dismissed after that point requires a Nolle Prosequi, which prosecutors file in only a small percentage of cases. Even when the case is ultimately dropped or resolved favorably, the arrest record remains unless you qualify for sealing or expungement.
Before that filing decision is made, the math is different. A prosecutor who has not yet filed can simply decide not to. There is no public record, no mug shot, no court docket. The difference between “no charges filed” and “charges filed and later dismissed” is the difference between a clean background check and a permanent mark that follows you through every job application, lease, and professional licensing review for the rest of your life.
This is why I tell people that the pre-filing phase is where a defense lawyer can do the most meaningful work. Once the Information is filed, we are fighting to dismiss a case the State has already committed to. Before it is filed, we are simply giving the prosecutor reasons to walk away.
What a Tampa Pre-Indictment Investigation Attorney Can Do Before Charges Are Filed
The work during this phase is specific and strategic. Here is what the process looks like when our firm gets involved early.
First, we contact the assigned filing prosecutor in the Hillsborough County State Attorney’s Office intake division or the Assistant U.S. Attorney in federal cases. That early conversation helps us understand what the government has, what it is missing, and where the review is headed.
Second, we prepare what is often called a pre-filing memo or mitigation letter. This document lays out the evidence the police report left out, points to weaknesses in the State’s theory, and, in many cases, includes documents, surveillance footage, medical records, or witness statements that change the picture entirely. A good mitigation memo gives a prosecutor a reason to file a lesser charge, decline the case, or reduce a felony to a misdemeanor before anything is ever on the docket.
Third, we shield you from the conversations that typically sink these cases. When a detective calls to follow up, that call comes to me. When federal agents want to ask questions, those questions go through counsel. You preserve your Fifth Amendment right to remain silent without looking evasive, because your lawyer is doing the talking.
Fourth, if the investigation involves a grand jury, we prepare accordingly. Grand jury proceedings are secret, and there is no defense lawyer in the room, but there is still significant work to be done on the outside, from advising any witnesses connected to you to preparing a response strategy if an indictment comes down.
Federal Target Letters and Grand Jury Subpoenas in the Middle District
Federal cases in Tampa move through the Sam M. Gibbons U.S. Courthouse downtown, and they follow their own rules. A federal target letter from the U.S. Attorney’s Office is a serious document. By the time you receive one, federal agents have usually been building the case for months. The letter is both a warning and an opportunity: a warning that you are the focus of the investigation, and an opportunity to respond before an indictment is returned.
If you have received a target letter, a subpoena, or a call from an FBI, DEA, HHS-OIG, or IRS Criminal Investigation agent, this is not a moment to wait and see. Federal criminal defense at this stage is about engaging with prosecutors early, protecting privilege, and making the case that charges should not be filed or, if filed, should be reduced. White-collar investigations, in particular, often turn on what happens in this window, because the paper trail is so extensive that a well-prepared defense response can shift the entire course of the case.
What to Do Today if You Think You Are Being Investigated
If you believe you are the subject of a criminal investigation, your next few decisions matter. Do not call the detective back without a lawyer. Do not delete text messages, emails, or social media posts, because that can create a separate obstruction charge. Do not explain yourself to friends or coworkers who may later be interviewed. Do write down everything you remember about the conduct under review, the people involved, and any contact you have had with law enforcement, and keep those notes in a place only you can access.
Then pick up the phone and call a criminal defense attorney who handles these cases regularly. For a deeper look at how to handle that initial contact, I recommend reading our guide on what to do if you are facing a police interrogation or investigation.
Why Board Certification Matters at This Stage
Board Certification in Criminal Trial Law is granted by the Florida Bar to fewer than 500 attorneys out of more than 100,000 practicing in the state. It requires documented trial experience, peer review, and a rigorous examination. For pre-indictment work, it matters because the prosecutor across the table knows the certification, knows what it took to earn, and knows that the lawyer they are dealing with has the trial credibility to back up a mitigation memo. That credibility affects how seriously your response is taken.
Both my wife, Christina, and I served as prosecutors in the 13th Judicial Circuit before joining the family firm my father founded in 1976. We have stood on both sides of the filing decision, which shapes the way we approach every pre-indictment case that comes through our doors.
Frequently Asked Questions
What is the difference between a pre-indictment investigation and a pre-file investigation in Florida?
The terms are often used interchangeably, but there is a technical difference. A pre-file investigation refers to Florida state cases in which the State Attorney’s Office files charges by Information. A pre-indictment investigation refers to federal cases in which a grand jury must return an indictment before most felony charges can be brought. Both phases share the same strategic reality: charges have not yet been filed, and early legal work can change the outcome.
Can a lawyer really stop charges from being filed in Tampa?
In many cases, yes. When a defense attorney engages with the Hillsborough County State Attorney’s Office during the intake review, presents exculpatory evidence, and raises legal issues the police report missed, prosecutors can and do decline to file charges. The outcome is never guaranteed, and every case turns on its specific facts, but early intervention gives the defense the best chance of a No Information decision.
How long do prosecutors have to file charges after an arrest in Florida?
Under Florida Statute § 907.04, a person held in custody must be released if no charges are filed within 21 days. For felonies not in custody, the State generally has 175 days under the speedy trial rule, though the statute of limitations for the underlying offense also applies. In practice, filing decisions in Hillsborough County are typically made within four to six weeks of the police report reaching the State Attorney’s intake division.
Should I talk to a detective who says they just want to clear something up?
No. A detective who is calling you has already identified you as a person of interest. Anything you say can be recorded, summarized in a report, and used to support charges. Politely tell the detective you are happy to cooperate through your attorney and end the conversation there. Invoking your right to remain silent is not evidence of guilt and cannot be used against you at trial.
What is a federal target letter, and how serious is it?
A federal target letter is a formal notice from the U.S. Attorney’s Office that you are the target of a federal grand jury investigation. It is serious. By the time a target letter is sent, federal prosecutors typically believe they have substantial evidence. The letter is also an opportunity, because it means you now know about the investigation and have the chance to respond with counsel before an indictment is returned.
