What to Do If You Are Being Investigated for a Federal Crime in Illinois?

There are many federal agencies that conduct investigations into suspected offenses like drug crimes, organized crime, internet offenses, and other criminal activity. What should you do if you are being investigated for a federal crime in Illinois? Federal investigations have the potential to lead to federal criminal charges, so it’s important to take them seriously. You should know the signs of a federal investigation and how to protect your rights.

Assessing Whether You Are Under Investigation

While it can be worrying if you think you are under federal investigation, it’s crucial to assess the facts of your situation to determine if an investigation is truly happening. If you suspect you are under investigation, make sure you are careful of the things you say to others in person, over text, and on phone calls, just in case. Some concrete things to look out for include:

• Contact from an agency for an interview
• A subpoena requesting records, testimony, and other information from you or your place of business
• Search warrants from a federal judge executed by agents to secure specific property or search a specific location
• Surveillance by federal agencies
• An interrogation by a federal agency
• A target letter sent by a U.S. attorney
• A federal agency raid of your home or business
• An arrest

Federal investigations may be conducted by the Federal Bureau of Investigation (FBI), the Drug Enforcement Administration (DEA), the Department of Homeland Security (DHS), the Office of the Inspector General (OIG), the Internal Revenue Service (IRS), or other agencies. If there is concrete evidence of an investigation like this, you should take steps to protect your rights.

What to Do When You Are Under Federal Investigation

If you are under federal investigation, there are several steps you should take to safeguard your future, quickly build a defense, and maybe even avoid criminal charges in the first place.

1. Get an Attorney: You should immediately contact a federal criminal defense attorney if you are under federal investigation. Talking with an attorney promptly can help you assess how serious the case against you is and take steps to prevent violations of your rights by investigators.
2. Keep Track of Information: It’s important to keep records of any communications with federal agencies and note down events related to the investigation. Read each part of any search warrant or subpoena, and ask for a copy of a warrant. Keeping all this information is crucial to better understand the specifics of the investigations and have evidence of the actions taken by the agency for a future case.
3. Do not Give Statements: If your legal counsel isn’t present, you should not answer questions asked by investigative agencies. Many people think that because they have done nothing wrong, there is no harm in a voluntary discussion, but this is not the case. Talking with investigative agencies can leave you in a much worse situation. Always talk with an attorney about the right steps to take.
4. Gather Evidence: You should preserve all documents, devices, and other information that supports your case. Never destroy or alter any information that might be related to an investigation, as this would likely be considered obstructing justice. Don’t discuss the alleged offense or the investigation with anyone else other than your defense attorney.

Criminal offenses at the federal level are very serious. Because investigative agencies have more resources than state investigators, cases are usually much stronger. The consequences of conviction can also be much more significant.

You have to take steps to protect your rights, your future, and your freedom. Working with a criminal defense attorney who knows the federal criminal justice system is crucial to protect yourself and potentially minimize or avoid the consequences of criminal charges.

FAQs

What Happens When You Are Under Federal Investigation?

If you are under federal investigation, you could face subpoenas, search warrants, interviews, and surveillance. If you suspect you are being investigated, it is crucial that you get in contact with an experienced criminal defense attorney who has handled federal cases. The exact process of an investigation varies depending on the agency investigating you, and an attorney can walk you through each step while protecting your rights.

What Triggers a Federal Investigation?

Federal investigations are often triggered by tips, audits, complaints, data breaches, surveillance, and information from other federal and state agencies. The investigation is used to determine if there is any criminal activity associated with the issue and whether there is enough evidence to charge the person or entity with a federal crime.

Federal investigations might revolve around suspected financial crimes, tax fraud or evasion, large-scale identity theft, drug trafficking, human trafficking, and national security concerns.

How Long Do Federal Investigations Usually Last?

How long federal investigations last depends entirely on the offense you are being investigated for, the evidence the agency can uncover, and the statute of limitations on the crime you are being investigated for.

If significant evidence is found quickly, investigations may close quickly, and you could face charges. If the agency cannot find enough evidence to file charges, the investigation may be closed, or the agency may continue investigating until the statute of limitations expires.

How Do You Tell If You Are Under Federal Investigation?

You may be able to tell if you are under federal investigation based on investigative actions like a search warrant of your property, subpoenas for your testimony or documents, interviews by federal agencies, or an interrogation.
