Understanding Why Different Agencies and Departments Are Targeting You

The Internal Revenue Service (IRS)

The IRS is a government agency tasked with the work of collecting taxes and enforcing tax laws. This agency also conducts criminal investigations targeting individuals and entities suspected of tax underpayments, income underreporting, and other criminal offenses under the Internal Revenue Code. The IRS is included among other agencies in accusations concerning Medicaid fraud, Medicare fraud, money laundering, and other federal financial crimes.

The Federal Bureau of Investigation (FBI)

The FBI is one of the most crucial federal enforcement agencies in the United States. It specifically holds responsibility for handling matters involving drugs, public corruption, organized crime, computer and internet crimes, terrorism, and other crimes. It also works jointly with other agencies such as the IRS, the OIG, and others depending on the federal crime in question.

The Drug Enforcement Agency (DEA)

This agency is tasked with the work of handling accusations concerning drug-related crimes. While these allegations may vary, they typically involve the manufacture and distribution of illicit drugs such as cocaine, heroin, methamphetamine, Lysergic Acid Diethylamide (LCD), and prescription drugs. Currently, the diversion control program is being prioritized by the DEA. It involves stopping the transfer of legally prescribed controlled drugs to other people, especially for illegal purposes. Opioids are the most common drugs that are diverted.

The Office of Inspector General (OIG)

The OIG is the Department of Health and Human Services’ (DHHS) law enforcement wing, and its mission is to protect DHHS’s programs as well as the health and welfare of individuals who benefit from these programs. It fulfills its mission by investigating and charging individuals or entities suspected of Medicare fraud, Medicaid fraud, Tricare fraud, and fraudulent actions concerning the Department of Labor (DOL), among many other offenses.

Understanding the Penalties for Federal Offenses

Federal criminal offenses carry a wide array of penalties. Imprisonment can last for as long as several decades, and fines can be as huge as millions of dollars. To understand the penalties you’re at risk for, contact a qualified attorney. Your Nashville federal criminal defense lawyer will comprehensively assess your situation to determine its scope and potential risks. If you hire us here are Oberheiden, P.C., we’ll get in touch with the relevant agencies or task forces to know more about the investigations you’re facing.

Penalties for federal crimes are potentially life-altering, and they can adversely affect both individuals and businesses. To increase the chances of achieving a favorable outcome, don’t hire a law firm that will give your case to a junior lawyer. You should only trust your case to an experienced federal defense attorney who knows how to act every step of the way without putting you at any risk of damaging consequences. As we mentioned earlier, we only work with senior attorneys here at Oberheiden P.C., who have many years of experience in handling federal criminal issues.

Frequently Asked Questions

What is a grand jury subpoena?


Federal prosecutors issue grand jury subpoenas when they believe that a party has information relevant to an ongoing investigation. If you receive a grand jury subpoena, you are obligated to comply. If you don’t the court may hold you in contempt. Grand jury subpoenas come in two forms, those that demand you provide certain evidence for the prosecutor’s inspection and those requiring you to physically appear and testify at a grand jury proceeding. In either case, you cannot rule out that the federal government believes you are involved in the case—at least on some level. To learn more about what the subpoena could mean, and what your options are to respond to the subpoena, contact a Nashville, Tennessee federal criminal defense lawyer immediately.

What types of charges can the federal government bring?


Federal prosecutors can file charges based on any violation of federal law. To a large degree, state and federal crimes overlap, giving federal prosecutors the option to prosecute many cases. However, in most situations, the federal government only gets involved in cases of perceived importance. For example, white collar criminal cases involving large amounts of money, complex healthcare fraud cases, and cases involving the transportation of drugs across state lines. Additionally, sometimes, the federal government will bring a case based on the fact that the charges are of national importance. If you face a crime in federal court, you should immediately reach out to a dedicated Nashville federal criminal defense attorney to discuss your options.

What is at stake in a federal prosecution?


Most federal crimes carry a wide range of potential consequences, including incarceration, federal probation, and fines that will make your head spin. In addition to these consequences of a federal criminal conviction, you may also face professional sanctions, such as the loss of a license to practice law or medicine, or the revocation of financial certifications. The bottom line is that there is a lot at stake in a federal prosecution, but you cannot know the full extent of what you are looking at before consulting with a Nashville, TN federal criminal defense attorney.
