What You Need to Know About Current FBI, IRS, DEA, and OIG Prosecutions in Texas

The U.S. justice system is divided into federal and state court. Federal courts have jurisdiction and authority to adjudicate federal criminal offenses, while state courts decide on violations of state offenses. In total, there are 95 federal districts in the U.S., four of which are located in Texas.

  • Northern District of Texas (with federal courts in Dallas, Fort Worth, Abilene, San Angelo, Amarillo, Wichita Falls, Lubbock)
  • Southern District of Texas (with federal courts in Houston, Galveston, Laredo, Brownsville, Victoria, Corpus Christi, McAllen)
  • Western District of Texas (with federal courts in Austin, Waco, El Paso, San Antonio, Del Rio, Pecos, Midland, Alpine, Fort Hood)
  • Eastern District of Texas (with federal courts in Tyler, Beaumont, Sherman, Marshall, Texarkana, Lufkin)

Combined, the four federal districts are among the largest federal enforcement territories in the country with the highest number of federal investigations of any state. This fact becomes all the more concerning since the Justice Department recently announced to intensify its efforts and to increase the number of federal prosecutions. Texans must be aware of this.

In 2017, Attorney General Sessions directed federal prosecutors to charge the most serious charges and pursue the harshest sentences. This policy significantly limits the discretion of federal prosecutors to charge a less serious offense, negotiate a plea agreement, or agree to more lenient sentencing.  The policy requires a supervising attorney to approve prosecutor decisions to charge a case with less than the maximum sustainable charge or a lesser sentence.  Any departure from the harsh new policy also requires the approval of a supervising attorney.  The rationale justifying the deviation from this harsh policy must be written in the case file.  Some critics argue that few prosecutors will ever risk exercising their discretion given these obstacles. The instructions address all federal agencies investigating federal offenses, such as the:

  • Department of Homeland Security
  • Federal Bureau of Investigation (FBI)
  • Internal Revenue Service (IRS)
  • Drug Enforcement Administration (DEA)
  • Office of Inspector General (OIG)
  • Department of Health and Human Services (HHS)
  • S. Attorney’s Office (USAO)

This policy denying prosecutor discretion to show leniency has even more devastating consequences because of the federal sentencing guidelines.  Federal judges typically follow the sentencing guidelines, which may include mandatory minimum terms.  Between the inflexible practices of the Department of Justice and Office of the Attorney General prosecutors and harsh sentencing guidelines, criminal defendants in federal court need a skilled advocate who understands these tough challenges and possesses a track record of success. This is what Texas is currently experiencing:

  • Increase of Federal Arrests & Federal Charges
  • Expansion of Search Warrant and Arrest Warrants
  • FBI Agents Attempting to Interview
  • Target Letters from the U.S. Attorney’s Office
  • Grand Jury Subpoena Asking for Records/Testimony

Our federal criminal defense attorneys have handled thousands of cases in federal court, but our success is evidenced by going beyond even our exemplary record in federal grand jury proceedings and trials.

FAQs: Important Questions Regarding Federal Prosecutions in the State of Texas

What Are the Penalties for Federal Felonies?

Federal felonies typically range from 0-10 years, but some, like mail and wire fraud and many violent offenses can go up to 0-20 years per each offense. More important than thinking that you will spend 20 years in jail is to understand how sentences within a Texas federal court system are actually imposed. First of all, there is only a sentencing if you got convicted or decided to plead guilty. Our job is to avoid this from happening. Next, most federal judges in Texas follow the Federal Sentencing Guidelines. These guidelines contain complicated arithmetic and mathematical formulas that allow the U.S. Probation Office to recommend a sentence range to the judge. Then, before the sentencing hearing, federal criminal defense attorneys can challenge and object to the recommendation. For example, attorney Nick Oberheiden has repeatedly obtained probation outcomes when the guidelines called for years in prison.

How Will I Know that I Am Under Investigation?

Besides rumors and agents trying to interview you or business affiliates, the safest way to know about an investigation is if you receive formal notice from the U.S. Attorney’s Office by way of a target letter, a grand jury subpoena, or other forms of correspondence from an Assistant United States Attorney. By the same token, you may also find out, then obviously, when agents come to your residence or business to execute a search warrant or federal arrest warrant. Because investigations are not public, it is important to act immediately at the earliest sign of an investigation. The sooner a skilled Texas federal criminal defense attorney can enter the case and defend your interest, the more likely it is that you will walk away with no federal criminal charges.

Does an Arrest Mean I Am Guilty?

Absolutely not! If you get arrested on federal charges in Texas, that means that a federal magistrate judge saw probable cause that you committed a federal crime, either yourself or by assisting someone else. It is important to realize that a simple affidavit from a federal agent investigating the matter can amount to probable cause. In other words, unlike the burden of proof the federal government has to show that you are actually guilty beyond a reasonable doubt, probable cause can be met rather easily. Oberheiden, P.C. has demonstrated the difference between an arrest and a conviction by obtaining dismissal and acquittals. If you or someone you deeply care for got arrested on federal charges you want a Texas federal criminal defense attorney to help with the federal bond hearing or with the defense case, then call Oberheiden, P.C. for a case discussion, a quote, and a free and confidential consultation.

How Should I Respond to a Target Letter?

If you receive a target letter from any of the U.S. Attorney’s Offices in Texas, that means that the federal government formally informs you that they have reason to believe that you violated a federal criminal statute or that you aided and assisted someone else in committing a federal offense (often referred to as a criminal conspiracy). Target letters are fairly common in Texas. They are not public, which means nobody but you and the federal government know about it; it is also important to understand that there is no case filed against you. While target letters essentially conclude the investigation, your receiving notice offers experienced attorneys an opportunity to take on the invitation from the prosecutor that is typically contained in the last paragraph of the target letter to meet, discuss (and possibly clarify) the matter. Oberheiden, P.C. has convinced prosecutors that have issued target letters not to actually bring charges by making compelling presentations at the U.S. Attorney’s Office on behalf of our targeted client. Target letters are extremely serious. You cannot afford to ignore them, you must not hesitate to address the issue. If you received a target letter, contact one of our experienced Texas federal criminal defense lawyers immediately. We will discuss the matter with you, hear your side of the story, and then open a dialogue with the prosecutor.

Should I Talk to the FBI Myself?

Federal agents are case investigators. They are expected to collect information so that the prosecutor can make a decision on whether or not to move forward with charges. One (common) way for federal agents to gather information is to make surprise visits to potential witnesses or targets of their investigation asking for an interview. While these FBI and DEA and OIG agents are well-trained and know how to assure you that their questions have “nothing to do with you,” caution is in order. It is never a good idea, no matter how innocent you are, to talk to FBI agents. Why? Because you don’t know what they actually want from you, you don’t know whether you are actually considered a mere witness. They don’t have to tell you and, often, they deliberately tell you what you want to hear (“it’s not about you”) to make you feel comfortable speaking with them—even if they already made the decision that you are a target and they are simply waiting for you to incriminate yourself. When agents approach you for an interview, politely insist on having a lawyer present. Let Oberheiden, P.C. speak with the agent and the prosecutor first to find out about the purpose of the interview and your role in the case. Talk to Oberheiden, P.C. and let us handle agents to protect your rights and interests.

When Should I Get a Lawyer?

Frankly, if you are even remotely involved in a federal case, be it as a distant witness or as the prime target, you should immediately consult with a Texas federal criminal defense lawyer who understands the federal laws and the federal criminal process. Make sure the lawyer does not handle anything but federal cases and that he/she has specific and compelling answers to your most pressing questions. In general, the sooner the right federal criminal defense attorney joins the defense case, the easier it is to influence the outcome. Feel free to call Oberheiden, P.C. for a free and confidential assessment to see if you need a lawyer and what a lawyer can do for you at this stage of your case.
