Potential Issues in Federal Criminal Cases

Various issues have the potential to arise during the course of a federal criminal defense case, and you need the best Dallas federal criminal lawyers to handle them. When taking timely and effective action can mean the difference between avoiding allegations altogether and facing a conviction at trial in federal court, you need to make sure that you are doing everything possible to resolve your federal case as quickly and strategically as possible. Here is just a small sampling of the issues that can arise during a criminal case at the federal level:


1. Illegally-Obtained Evidence

When conducting federal criminal investigations, federal agents and prosecutors do not have free reign. Their actions are limited by the protections afforded in the U.S. Constitution; and, when they violate suspects’ or defendants’ constitutional rights, any evidence obtained as a result of the violation may be deemed illegally-obtained.

Illegally-obtained evidence is inadmissible in federal court (subject to certain limitations). However, if you wish to keep illegally-obtained evidence out of your case, it is up to you to do so. Unfortunately, many people who lacked an experienced federal criminal lawyer have been convicted on evidence that should have been deemed inadmissible in federal court.


2. Conspiracy Allegations

Under the federal conspiracy statute, 18 U.S.C. § 371, you do not have to commit a substantive offense in order to face substantial fines and long-term imprisonment. Various other federal statutes contain conspiracy provisions as well; and, due to the breadth of these statutes, they are among federal prosecutors’ most-potent tools in federal criminal investigations and prosecutions. If a prosecutor can argue that you were party to a formal or informal agreement to commit a federal crime and any of your alleged co-conspirators executed an “overt act” toward the commission of a federal crime, this can be enough to warrant prosecution in federal district court.


3. Attempt Allegations

Under federal law, the targets of federal investigations can also face charges for attempt in the absence of evidence of a completed criminal offense. Often, charges for attempt carry the same penalties as charges for the allegedly-attempted federal crime. Due to the potential for attempt accusations, individuals and organizations being targeted for federal prosecution must be extremely careful to avoid relying on defense strategies that could expose them to prosecution for an “unsuccessful” federal crime.


4. Multiple Related and Unrelated Charges

While certain federal statutes target specific substantive federal crimes (such as healthcare fraud or drug trafficking), other statutes impose severe penalties for acts taken in furtherance of – or in conjunction with – specific criminal conduct. As a result, in federal cases it is not unusual for defendants to face multiple charges for both related and unrelated federal crimes.

For example, some of the most-common accusations in federal cases are mail fraud, wire fraud, and money laundering. Under the broad language of the mail fraud, wire fraud, and money laundering statutes, almost any criminal conduct will have the potential to trigger prosecution under these statutes. In a healthcare fraud case, providers will often face allegations of multiple healthcare-related offenses; and, in securities fraud cases, companies will often face charges for multiple corporate crimes. Various other alleged “criminal enterprises” can trigger multiple federal accusations as well.


5. Confidential Informant or “Co-Conspirator” Testimony

Another risk in a federal case is the risk of a federal prosecutor obtaining testimony from a confidential informant or an alleged co-conspirator. If someone else who has a vested interest in the outcome of your case testifies against you, you will need to overcome this testimony as part of your defense.


6. Sentencing Guidelines

In most federal criminal cases, the potential sentences are outlined in the Federal Sentencing Guidelines (the “Guidelines”). While the Federal Sentencing Guidelines are not binding, prosecutors and judges will often rely on the Guidelines in determining what penalties to seek and impose in the event of a conviction at trial. However, often it will be possible to obtain a below-guideline plea deal or sentence (assuming penalties cannot be avoided entirely); and, a federal criminal defense lawyer at Oberheiden, P.C. has significant experience protecting clients against the penalties prescribed by the guidelines for federal sentencing.

Potential Penalties in Federal Criminal Cases

While the Federal Sentencing Guidelines establish a range of potential fines and prison sentences for most crimes, various federal statutes impose additional penalties as well. Depending upon the specific federal criminal charges (or charge) involved, the potential penalties can be severe, which is why you need the best federal criminal lawyer to support you. The penalties in a federal criminal case may include:

  • Federal Imprisonment – Most serious federal crimes carry the potential for a minimum of several years of incarceration. Various factors can increase the potential prison sentence that is on the table; and, when prosecutors pursue multiple counts of multiple federal criminal charges, defendants can easily be at risk for being sentenced to decades behind bars.
  • Probation – If penalties cannot be avoided entirely, in many cases, the best defense strategies focus on securing probation in lieu of a term of imprisonment.
  • Fines – Statutory fines vary for individual and corporate defendants; however, in all cases, the aggregate fines imposed for federal offenses can far surpass what most people and companies can afford to pay.
  • Restitution, Recoupments, and Other Financial Penalties – Federal criminal defendants convicted of certain crimes may be sentenced to restitution, recoupments, and other financial penalties as well.
  • Other Statutory Penalties – In certain types of cases, federal criminal defendants can also face additional statutory penalties. Some examples include Medicare and Medicaid exclusion (in cases of healthcare fraud) and loss of eligibility for DEA or SEC registration (for prescription and securities-related offenses, respectively).

Q&A with the Federal Criminal Lawyers at Oberheiden, P.C.

Q: What is different about state and federal criminal cases?

Joanne Fine Delana, federal attorneyThe differences between a state and federal criminal case are almost too many to list. From the agencies involved to the penalties that are on the table, effectively defending against federal criminal charges requires a federal criminal lawyer with particular experience in all of the unique aspects involved.

At Oberheiden, P.C., we focus our practice on federal criminal matters. In addition, many of our attorneys are former federal prosecutors who spent years (and, often, decades) pursuing criminal indictments on behalf of the federal government in federal courts. As a result, we are intimately familiar with the complexities of the federal criminal process and federal cases, and we offer the insights of seeing our clients’ cases from the government’s perspective.

Q: How is facing a federal criminal charge different from facing a criminal charge in state court?

Richard Simmons, federal attorneyFederal and state criminal proceedings bear virtually no resemblance to one another. From the agencies that are involved to the laws and court rules that apply, everything is different in a federal criminal case. The procedures involved in federal criminal cases are very different from those involved in state criminal cases as well; and, generally speaking, the stakes are much higher if you have been charged with a federal crime.

Q: Which federal agencies are involved in investigating and prosecuting alleged white-collar crimes?

Wilfred Rattigan, federal criminal defense attorneyMultiple federal agencies are involved in investigating and prosecuting white-collar federal crimes. The specific agency (or agencies) involved will depend on the type (or types) of allegations at issue. The U.S. Department of Justice (DOJ) and Federal Bureau of Investigation (FBI) are the nation’s top law enforcement and domestic investigative agencies, respectively, but numerous other agencies are involved in investigating various types of crimes and federal offenses as well. At Oberheiden P.C., we have experience representing clients in investigations of federal charges involving:

  • Immigration and Customs Enforcement (ICE) and U.S. Citizenship and Immigration Services (USCIS)
  • Internal Revenue Service Criminal Investigations (IRS-CI)
  • U.S. Department of Defense (DOD)
  • U.S. Department of Labor (DOL)
  • U.S. Department of Health and Human Services Office of Inspector General (HHS-OIG)
  • U.S. Drug Enforcement Administration (DEA)
  • U.S. Securities and Exchange Commission (SEC)
  • U.S. Small Business Administration Office of Inspector General (SBA-OIG)
  • U.S. Postal Inspection Service (USPIS)
  • Other federal administrative and law enforcement agencies

Q: Should you hire a federal criminal defense lawyer to represent you during a federal criminal investigation?

David Raben, federal lawyerYes, without question. If you are aware that you are under investigation, the government already has the upper hand. Investigations often last months, and sometimes years, and federal agents and prosecutors strategically decide when to make their intentions known. You should hire a legal team immediately to intervene in the investigation and begin gathering the information needed to build a strategic defense.

While there are many mistakes that you need to avoid if you are facing a federal white-collar criminal investigation, the biggest mistake you need to avoid is waiting too long to engage federal defense counsel.

Erick Cruz, federal attorneyOften, it is possible to resolve federal investigations without charges being filed. However, in order to achieve this result, you must hire a law firm to intervene in the investigation and deal with the investigating agency (or agencies) on your behalf. Our firm represents individuals and corporations in federal white-collar investigations across the country, and we can take defensive action immediately if necessary.

Q: What does it mean if you have been served with a criminal complaint?

Donald Lykkebak, federal attorneyA criminal complaint is a formal pleading document filed by federal prosecutors at the U.S. Attorney’s Office. Criminal complaints set forth allegations of unlawful conduct; and, once a criminal complaint has been served, this gives federal agents lawful authority to make an arrest. Following an arrest executed pursuant to a criminal complaint, federal prosecutors have 30 days to seek a grand jury indictment.

Karen Pickett, federal lawyerWhile federal prosecutors previously reserved criminal complaints for federal cases involving allegations of violent crimes and high-risk targets, the U.S. Attorney’s Office has recently begun filing criminal complaints in white-collar instances. If you have been served with a criminal complaint, you need to engage a federal criminal defense lawyer immediately.

Q: What are some of the most common criminal charges in federal white-collar cases?

Michael Rataj, federal defense attorneyThere are numerous federal offenses that fall under the “white-collar” umbrella at the federal level, and the charges filed in any particular case will depend on the specific facts (or alleged facts) involved. However, there are a number of federal crimes that are extremely broadly defined, and this allows federal prosecutors to bring accusations for these crimes in a wide range of federal cases. In particular, it is fairly common for federal white-collar indictments to include charges for:

  • Aggravated identity theft
  • Bank fraud
  • Mail fraud
  • Money laundering
  • Tax evasion and tax fraud
  • Wire fraud

Bill Tunkey, federal attorneyThese are in addition to the specific substantive accusations underlying the government’s case. From corporate espionage and intellectual property theft to healthcare fraud and securities fraud, federal white-collar criminal cases can target a broad array of alleged criminal activities.

Q: What defenses can be used to avoid conviction in federal district court?

Kamille Dean, federal attorney The defenses that are available in any particular federal white-collar criminal case will depend on the facts at hand and the federal laws and statutes at issue. Many federal white-collar statutes require proof of multiple “elements,” and challenging the DOJ’s evidence of even a single element can be enough to avoid a conviction in federal courts. Many of these statutes contain specific exceptions and “safe harbors” as well, and affirmatively demonstrating compliance can be an advisable strategy in some instances.

<!– Brandon Johnson, federal defense attorney –>In addition to defenses that are specific to the crime (or crimes) alleged, defendants in federal white-collar cases can also assert defenses under the U.S. Constitution. For example, if federal agents and federal investigators raided your home or office and seized evidence without a valid search warrant, then the evidence they obtained may be inadmissible in court.

Q: What are the possible sentences for white-collar federal crimes?

Aaron Wiley, federal attorneyIf your investigation leads to charges, the outcome of your case may depend directly on the quality of your federal criminal attorney. Being charged does not necessarily mean that you will be convicted – or even that you will face trial. In our decades of experience, our federal criminal attorneys have helped clients across the country obtain favorable resolutions for federal charges through:

  • Negotiating plea deals for probation and reduced sentencing
  • Convincing prosecutors and judges to drop charges prior to trial
  • Obtaining “not guilty” verdicts in open court

Joseph Nascimento, federal defense lawyerEven if you go to court and lose, this does not mean that your case is over. You could have any of a number of different grounds to file an appeal or seek to have your conviction set aside. While challenging a conviction is absolutely a means of last resort, when we take cases to trial, in addition to presenting a vigorous defense we also focus on preserving all potential grounds for having a potential conviction overturned.

Q: Are you safe if you did not go through with committing a contemplated white-collar crime?

Cameron Blazer, federal attorneyNo, you are not. Under federal law, individuals charged with attempt and conspiracy can face the same penalties as individuals charged with the commission of the underlying offense. As a result, when defending against federal white-collar allegations, it is imperative that you execute an informed strategy with the advice and representation of highly-experienced federal defense counsel and federal criminal defense attorneys.

Q: Is it possible to negotiate a plea bargain in a federal white-collar case?

Peter Phillips, federal criminal defense attorneyYes, if you are charged with a white-collar offense at the federal level, it is possible to resolve your case prior to trial through the negotiation of a plea bargain. A federal prosecutor will entertain plea negotiations in most instances; and, if your risk of conviction at trial is high, it may be in your best interests to negotiate a plea. However, it is possible to have criminal charges dismissed prior to trial in some instances as well; and, again, in order to make informed decisions about your defense strategy, you need to hire an experienced federal defense attorney promptly.

Q: What makes Oberheiden P.C. different from other federal criminal defense law firms?

Terry Frank, federal lawyerAt Oberheiden P.C., our practice is devoted to representing clients in high-stakes federal matters. This distinguishes us from most other criminal defense law firms in the United States. Another distinguishing factor is our firm’s composition exclusively of senior attorneys and defense consultants, many of whom are former federal prosecutors and investigative agents with the DOJ, FBI, and other agencies.

Joseph Reinke, federal defense attorneyIf you are under investigation or facing charges for a federal white-collar crime, your choice of legal representation matters immensely. Contact us for a complimentary case assessment and learn why individuals and businesses nationwide trust Oberheiden P.C. law firm for federal white-collar criminal defense.

Q: What are some examples of Oberheiden, P.C.’s case results?

The following are three examples of our recent successes in federal criminal defense matters:

  • Daniel Smith, federal attorney , federal lawyerWe represented a client who was under investigation by the DOJ and the Federal Bureau of Investigation (FBI) for alleged Medicare fraud. Over the course of several meetings with the DOJ’s attorneys, our federal criminal defense lawyers were able to close the investigation without charges being filed.
  • We represented another client in a criminal Medicare fraud investigation involving numerous federal agencies. Despite the extensive resources that the government dedicated to the investigation, we were able to successfully demonstrate that our client had not engaged in criminal conduct. We were also able to successfully disprove any civil liability, resulting in the investigation being closed without any charges or liability.
  • We represented a client who was facing long-term incarceration after being indicted for alleged involvement in a healthcare fraud conspiracy. Despite the fact that the federal sentencing guidelines called for years of incarceration, Dr. Nick Oberheiden was able to convince the federal judge presiding over the case to sentence our client to probation.

Q: What are the potential outcomes if I am charged with a federal crime?

Pascual Meyer, federal criminal defense lawyerThese results are representative of the types of outcomes we have been able to achieve for a significant number of our clients (however, results are not guaranteed). See more examples of our federal criminal case results.

Q: What steps should I take if I am being targeted by the federal government?

If you are being targeted by the federal government, or if you believe that you may be under investigation, there are several steps that you should try to take immediately. These include:

  • Ellen Comley, federal criminal defense attorneyExercising your right to remain silent and not supplying any information or records to the government except on the advice of legal counsel.
  • Avoiding discussing the case with anyone other than your federal criminal attorney, and advising your employees and anyone else familiar with the matter to only discuss the case as directed.
  • Preserving any records, hardcopy or electronic, that may be relevant to the investigation (destroying evidence can lead to additional charges with severe penalties).
  • Assessing whether you need to take any action to prevent ongoing legal violations that could lead to further prosecution.
  • Coordinating a comprehensive defense strategy with a federal criminal lawyer focused on resolving the investigation without charges being filed.
