This Is Why You Need Experienced Attorneys For Current Prosecutions in Miami

FBI and DEA investigations are at an all-time height in Miami and throughout Southern Florida. Worse, in light of recent Justice Department instructions to federal prosecutors in Florida to intensify their efforts to prosecute federal offenses, the wave of arrests, search warrant executions, and grand jury proceedings is likely to even increase.

In general, the Federal Bureau of Investigation (FBI) and the Drug Enforcement Administration (DEA) are tasked to detect violations of federal law and to report their investigative findings to federal prosecutors, typically referred to as Assistant United States Attorneys (AUSA). There are several ways federal agents from the FBI, the DEA, but also other federal law enforcement agencies such as the IRS, the Department of Homeland Security, the Department of Health and Human Services (HHS), and the Office of Inspector General (OIG) gather information.

The two most common ways are witness interviews and grand jury subpoenas. Many people contact Oberheiden, P.C. in Florida because they were just contacted by FBI agents or became aware of agents trying to interview business or personal affiliates. When this happens, all caution is in order. Make no mistake: federal agents are trained and paid to put people behind bars. Importantly, unlike you, FBI and DEA agents are under no obligation to tell the truth. By contrast, quite often, to gain your trust and to break the ice, agents will commence an interview request by telling you that they just have a few questions and that the case is not about you. Rarely is that correct. When you become aware of federal agents’ activity, you should immediately contact the proven and winning Miami federal criminal defense attorneys at Oberheiden, P.C. to assess the situation, evaluate your exposure, and make sound decisions that you will not need to regret later on.

Besides receiving a visit from agents for an interview request, the Justice Department in Miami also issues grand jury subpoenas. Purpose of these subpoenas is to collect information, either witness interviews or documents, from people that the federal prosecutor in charge of the investigation believes to be a person of interest or someone possessing information. Anyone subject to a grand jury proceeding must be aware that the grand jury is tasked to determine whom to prosecute and whom to indict. That said, grand jury proceedings are serious matters and anyone involved or being contacted by a federal grand jury is at risk of being dragged into a federal criminal case. Having being previously in charge of grand jury proceedings, the number one advice from the former federal prosecutors of Oberheiden, P.C. is to not underestimate a subpoena. Mistakes cannot be undone and, at the Department of Justice, we have seen many times how bad responses to grand jury subpoenas have turned original witnesses into targets.

What Types of Offenses are FBI and DEA Agents Investigating in Miami?

Of all the federal law enforcement agencies, the FBI is arguably the best known and the one tasked with the broadest jurisdiction when it comes to federal law enforcement investigations. Vice-versa, the DEA is a more specialized agency with a focus on combating drug related offenses, including so-called street drugs like Methamphetamine, Heroin, Marijuana, Cocaine, and the more modern Furanyl Fentanyl and Carfentanil. In addition to these illicit drugs, the DEA has shifted more and more to also investigate physicians, pharmacies, and consumers for allegations of illegal distribution and possession of narcotics and opioids. Recent charges in Miami that involve the FBI and the DEA included:

FBI: Kickbacks & Medicare Fraud

  • 18 U.S.C. 1349 Conspiracy to Commit Health Care Fraud
  • 18 U.S.C. 1347 Health Care Fraud
  • 42 U.S.C. 1320a-7b(b)(1)(2) Payment/Receipt of Illegal Remuneration

DEA: Opioid & Drug Charges

  • Opioids: 21 U.S.C. 841 Distribution and Possession with Intent to Distribute Narcotics/Opioids
  • Street Drugs: 21 U.S.C. 846 Conspiracy to Distribute Furanyl Fentanyl, Carfentanil, Methamphetamine, Heroin, Marijuana, or Cocaine etc.
  • 21 U.S.C. 846 Conspiracy to Possess with Intent to Distribute a Controlled Substance

FBI: Bank Fraud, Mail/Wire Fraud

  • 18 U.S.C. 1344 Bank Fraud
  • 18 U.S.C. 1349 Conspiracy to Commit Wire Fraud
  • 18 U.S.C. 1349 Conspiracy to Commit Mail Fraud
  • 18 U.S.C. 1341 Mail Fraud
  • 18 U.S.C. 1343 Wire Fraud

Having previously supervised federal cases at the Department of Justice for decades, many of our attorneys have first-hand knowledge and an in-depth understanding as to how FBI and DEA agents in Florida and the rest of the country approach a case— and what can be done to intervene into a pending investigation.

This Is Why Clients in Miami Trust Oberheiden, P.C.

When your freedom and your financial future are at stake, the selection of competent counsel becomes one of the most important decisions you will ever make.

Miami is home to many great lawyers and excellent law firms. However, not every lawyer qualifies equally to handle your important case. For example, Miami’s best real estate attorney may not be the best fit for handling a complex DEA investigation and, similarly, the best traffic and DUI attorney in South Florida may lack the day-to-day experience to negotiate with FBI agents and federal prosecutors.

What sets Oberheiden, P.C. and our Miami federal criminal defense lawyers apart is our exclusive focus on federal criminal defense matters and our in-depth understanding of the American federal justice system gained in more than five decades as key prosecutors at the Department of Justice.

If you are facing an FBI or DEA investigation, who could be more knowledgeable than those lawyers that:

  • Previously Supervised DEA and FBI Investigations at the U.S. Attorney’s Office
  • Have Decades of FBI and DEA Defense Experience
  • Can Provide Proven Defense Strategies Against Federal Cases Involving the FBI, DEA, and the Department of Justice

Important Questions About Miami FBI and DEA Investigations

What Should I Do When FBI Agents Want to Speak With Me?

Immediately call experienced Miami federal criminal defense attorneys when agents come by your house or your business. Typically, they will say that the case is not about you and that they just have a few questions—but this statement can be misleading because agents are tasked to investigate federal criminal cases and will apply any technique to get admissions or comments from subjects or targets of an investigation. Remain polite and insist on having your attorney present. It is your constitutional right and the best way to protect your interests.

What Questions Should I Ask Lawyer Candidates to Find the “Best” Federal Criminal Defense Attorney for My FBI Case in Miami?

The seriousness of federal cases requires careful consideration when it comes to selecting the right attorney. Necessarily, the choice must be based on subjective confidence and trust that are based on objective facts like the lawyer’s experience, prior results, and reputation. The following questions may help identifying the best attorney for your specific case.

  • What Percentage of Your Practice Is Dedicated to Federal Criminal Defense?
  • How Often Do You Avoid Charges in Federal Criminal Investigations?
  • How Many Federal Criminal Trials Have You Handled Before?

Oberheiden, P.C. is a federal criminal trial law firm that assists clients in Miami, Dade County, and Southern Florida. Throughout our careers at the Department of Justice and as federal defense attorneys, we have handled more than a thousand federal proceedings. In general, the earlier clients contact us about pending or potential criminal investigations, the higher the chance that we can avoid criminal charges or an expansion of the investigation. We have avoided charges in approximately 90% of such cases. Similarly, our committed Miami federal criminal defense lawyers have obtained acquittals, dismissals, and favorable trial verdicts in federal courts throughout the United States.

If I Get Convicted of a Federal Crime, Will I Go to Prison?

Not necessarily. Federal sentencing is a complicated event. While most federal judges in Miami follow the Federal Sentencing Guidelines, it is nonetheless possible to AVOID jail time even though the recommendation from U.S. Probation suggests incarceration. For example, attorney Nick Oberheiden positively surprised numerous clients by obtaining probationary outcomes in seemingly “hopeless” cases. The best defense against convictions and sentencing is an effective defense strategy from the moment you learn about a potential case against you.
