Q: What do I need to know if I am being targeted in a federal investigation?

If you are being targeted in an FBI, OIG, IRS, or DEA investigation, there are several things you need to know. From confirming whether the government’s investigation is criminal in nature to identifying the specific defense(s) you have available, there are several pieces of information it will be important for you to ascertain as soon as possible. It will also be important for you to:

  • Determine the scope of your obligation to respond to any formal or informal requests for information;
  • Advise your employees on how to interact (or, more specifically, how not to interact) with federal agents during the investigation;
  • Identify any prior or ongoing issues that may support civil or criminal federal charges; and
  • Engage experienced defense counsel immediately to intervene in the government’s investigation and begin working toward a favorable resolution.

Q: How do I know if the allegations against me are true?

In order to determine whether the allegations against you are true, you first need to ascertain exactly what those allegations are. Surprisingly, this is not as easy as it sounds. While you might expect to be provided with a clear explanation of why federal authorities are looking into your business or practice, the reality is that it often takes aggressive intervention and extrapolation from factors such as the type(s) of questions you are asked and the agency(ies) involved in order to determine why you are at risk for federal criminal prosecution.

Once you identify why you are under investigation, then you can begin to conduct an internal assessment to determine if, and to what extent, any of the allegations may be true. However, you should never assume that allegations are true simply because the federal government has launched an investigation. Our San Diego federal criminal defense lawyers routinely resolve our clients’ cases without charges being filed. In many cases, investigations are triggered by false allegations from disgruntled former employees and competitors seeking to take advantage of the qui tam (or “whistleblower”) provisions of the False Claims Act.

Q: What result can I hope to achieve in my federal criminal case?

We approach every case with the goal of protecting our client against penalties entirely. This is true whether we get involved during the government’s investigation (which is typically the case), or if we are asked to step in and defend a client at trial. However, the result of every case depends upon numerous different factors. To provide you with a personalized case assessment, we will need to learn about your individual set of circumstances.

Q: How can I defend myself against the federal government?

In order to defend yourself against the federal government effectively, you will need experienced legal representation. When you are facing off against highly experienced federal agents and prosecutors, there is simply no substitute for having an experienced defense team on your side.

Q: How soon can Oberheiden, P.C.’s defense team start handling my case?
