Hawaii Federal Criminal Defense Attorneys

Oberheiden P.C. is a team of senior defense attorneys and former U.S. Department of Justice (DOJ) prosecutors who represent clients in high-stakes federal criminal matters. If you are under investigation, if you have been subpoenaed to appear before a federal grand jury, or if you are facing federal charges in Honolulu, Pearl City, or anywhere in Hawaii, contact us for a free consultation.

At the federal level, criminal charges can lead to enormous fines and long-term imprisonment. For government contractors, federal program participants (i.e. Medicare and Tricare providers), and companies that are subject to federal registration, facing charges can also lead to loss of government business and loss of approval. In many cases, simply facing an investigation can have damaging repercussions as well, as U.S. Department of Justice (DOJ) press releases, media coverage, and social media posts can quickly spread news of the inquiry across Hawaii and throughout the U.S. mainland.

If you are under federal investigation or facing federal criminal charges in Hawaii, avoiding these consequences will require a strategic and effective defense. Federal agents and prosecutors are coming after you, and they are not going to stop pursuing your case unless you give them reason to do so. As a suspect, target, or defendant in a federal criminal case, you need to protect yourself. You need to make smart decisions, and you need to give yourself every possible opportunity to avoid a conviction.

Nick is extremely professional and knows what he is doing. He is also very kind as a person (unless he is in court!) I would recommend him to just about anyone if they need an amazing lawyer that is top notch and would frankly be scary to face in the court room. He will always do a great job representing his clients. Thank you very much.read more

When I was faced with one of the most terrifying and unexpected situations in my life, I called Dr. Oberheiden. I had vetted other attorneys and came right back to him. His knowledge, expertise, and reassuring presence made the decision easy. Throughout my case, his level of communication was what I needed and expected. He constantly updated me on the status and progress of my case and was able to “talk me off the ledge” when the stress of it all would set in. He is simply the best of the best...there’s not a question about it.read more

Federal Investigations: Are You a Witness, Suspect, or Target?

When you are contacted in regard to a federal criminal investigation, one of the first questions you need to answer is: Are you currently being treated as a witness in the government’s investigation; or, are you suspected of committing a federal crime? In many cases, federal agents will approach suspects and targets saying that they are “looking for information,” suggesting that the investigation is focused on someone else. However, this may or may not actually be the case. Contrary to popular belief, federal agents do not have to read suspects’ rights before asking any questions—the Miranda warning is only required prior to custodial interrogations.

In any case, when dealing with a federal investigation, extreme caution is required. Voluntarily sharing information or disclosing records can enhance your risk of prosecution; and, even if you are currently a witness, this could change in an instant. As your federal criminal defense counsel, we will communicate with federal agents on your behalf, and we will work diligently and strategically to prevent the investigation from leading to criminal charges.

In our federal criminal defense practice, we have successfully represented clients who were being targeted by all major federal law enforcement agencies. With our past federal government experience and our experience in thousands of federal matters, we understand what works – and what doesn’t – when it comes to convincing federal agents not to pursue investigations farther. Contact us to learn more about our experience in matters involving:

  • Drug Enforcement Administration (DEA)
  • Federal Bureau of Investigation (FBI)
  • Internal Revenue Service (IRS)
  • U.S. Attorney’s Office (USAO)
  • U.S. Department of Defense (DOD)
  • U.S. Department of Health and Human Services (HHS)
  • U.S. Department of Homeland Security (DHS)
  • U.S. Department of Justice (DOJ)
  • U.S. Postal Inspection Service (USPIS)
  • Securities and Exchange Commission (SEC)
  • Various federal Offices of Inspector General (OIG)

Federal Prosecutions: What are the Chances of Your Case Going to Verdict?

If it is too late or otherwise not possible to prevent charges from being filed, what are the chances of your case going to trial? More importantly, what are the chances that the judge or jury will find you guilty of one or more of the federal crimes alleged?

We don’t know. Or, at least, we don’t know yet. In order to assess your potential exposure, we will need to gain a clear understanding of the current status of your case, from the amount of evidence the government has against you to the number of days until your trial.

If you have already been indicted, then your case will most likely be resolved by a plea deal or by a verdict in court. However, at Oberheiden P.C., we also have experience getting our clients’ indictments dismissed prior to trial. This, we believe, is one of the major factors that sets us apart from other law firms. We never assume that a favorable resolution is off of the table, and we never take our foot off of the pedal until we have achieved the result we are targeting.

I Am Being Targeted by Federal Authorities in Hawaii. What Now?

You are in the federal government’s crosshairs. You are accused of committing a serious white-collar offense, attempting to commit a serious white-collar offense, or participating in a federal conspiracy, and you are facing substantial, life-altering penalties. What do you need to do?

1. Do Not Say Anything

At this point, you should not be saying anything to federal authorities. Assert your right to remain silent and your right to seek legal counsel, and politely decline any requests for information – no matter how innocuous they may seem.

2. Make Sure You Aren’t Breaking the Law

Breaking federal law while you are under investigation is one of the surest ways to fast-track your case to the grand jury. Make sure you know the law, and make sure you are not enhancing your exposure by continuing to do things that could substantiate federal charges.

3. Determine What Deadline(s) You Need to Meet

If you have received a subpoena, summons, civil investigative demand (CID), or any other formal request for information or for your appearance in court, make sure you know all relevant deadlines. Depending on the nature of the request, failing to meet a deadline could result in a federal charge for contempt.

4. Avoid Common Mistakes

There are numerous mistakes that can jeopardize your ability to assert a successful defense during a federal case. Know what mistakes you need to avoid, and make proactive and informed decisions about your defense.

5. Speak with a Federal Criminal Defense Attorney

If you are facing a federal investigation or federal charges in Hawaii, you need experienced federal criminal defense representation. Engaging legal counsel promptly will afford the greatest opportunity to resolve your case short of a conviction.
