    What Can the Agency (or Agencies) Involved Tell You about Your Federal Case?

    Actually, quite a lot. The FBI, OIG, IRS, DEA, and other agencies’ jurisdictions overlap in many respects. Knowing the agency, or agencies, behind your situation is one of the first steps to learn the scope of the inquiry. With this information, we can develop defense strategies likely to be most effective in your case.

    Federal Bureau of Investigation (FBI) Investigations

    The FBI investigates allegations of:

    • Cybercrimes,
    • Public corruption,
    • Organized crime,
    • Corporate fraud,
    • Healthcare fraud, and other serious federal offenses.

    It has field offices around the country, including one in Fresno, CA.

    Office of Inspector General (OIG) Investigations

    The OIG gets involved in cases involving allegations of Medicare and Medicaid fraud. It frequently works with the DOJ, FBI, and other agencies in large-scale healthcare fraud investigations.

    Internal Revenue Service (IRS) Investigations

    Through its criminal enforcement division, the IRS investigates and assists in prosecuting alleged tax evasion and other tax crimes. Like the OIG, the IRS’s criminal enforcement division is often just one of several agencies involved in large operations and other federal law enforcement initiatives.

    Drug Enforcement Administration (DEA) Investigations

    The DEA is the primary agency responsible for enforcing the nation’s drug laws. This includes laws applying to physicians, pharmacists, and other healthcare providers. It works closely with the DOJ to target providers suspected of engaging in opioid drug diversion.

    Frequently-Asked Questions (FAQs): Federal Criminal Defense in Fresno, CA

    Q: What are the potential penalties under the Federal Sentencing Guidelines?


    Federal Sentencing Guidelines establish rules and policies for sentencing in federal criminal cases. Penalties for individual criminal offenses are established by statute. Under the False Claims Act, criminal penalties include up to $25,000 in fines (for individuals) and five years in prison for each offense. Federal criminal cases often involve multiple “counts” of a variety of different offenses. Fresno residents in these investigations can face overwhelming fines and decades of federal imprisonment.

    Along with fines and prison time, licensed providers, executives, board members, and others convicted of federal crimes can face additional penalties including:

    • Recoupments and denial of pending payments
    • Pre-payment review
    • Program exclusion (Medicare, Medicaid, and Tricare ineligibility)
    • Professional licensing action (suspension or revocation)

    Q: What are some potential defense strategies in federal criminal investigations?


    Once again, the specifics will depend upon the statute (or statutes) under which you are being investigated. In healthcare fraud cases involving allegations under the Anti-Kickback Statute, providers can often use the statute’s “safe harbors” as affirmative defenses to criminal guilt.

    The government must prove every element of each alleged offense beyond a reasonable doubt. Identifying problems in the government’s evidence or flaws in its reasoning can be enough to avoid criminal prosecution. This is a preferred tactic as opposed to “proving your innocence” with an affirmative defense. It requires a thorough understanding of the specific statute (or statutes) you are alleged to have violated.

    Then, there are the constitutional and common law defenses. These include defenses such as:

    • Violation of the protection against unreasonable searches and seizures
    • Violation of your right to remain silent or your right to legal counsel
    • Violation of your right to a speedy trial
    • Lack of criminal intent
    • Entrapment or duress
    • Alibi or mistaken identification
    • False “whistleblower” allegations

    Q: What statutes do federal prosecutors use to pursue criminal charges in white-collar cases?


    In white-collar cases, federal prosecutors have numerous statutes at their disposal. For example, our Fresno federal criminal defense lawyers represent clients in investigations involving allegations under:

    • 18 U.S.C. 371 (criminal conspiracy)
    • 18 U.S.C. 1028A (identity theft)
    • 18 U.S.C. 1341 (mail fraud)
    • 18 U.S.C. 1343 (wire fraud)
    • 18 U.S.C. 1344 (bank fraud)
    • 18 U.S.C. 1347 (healthcare fraud)
    • 18 U.S.C. 1357 (money laundering)
    • 21 U.S.C. 841 (distribution of controlled substances)
    • 26 U.S.C. 7206 (tax fraud)
    • 31 U.S.C. 3279 (false and fraudulent claims)
    • 42 U.S.C. 1320a-7(b) (illegal kickbacks)

    Q: How soon will I know the likely outcome of my federal case?


    This is a question we cannot answer until we know the specific facts involved. Sometimes, we can tell our clients with reasonable certainty we can achieve a favorable outcome fairly quickly. In others, it will take time before our attorneys can assess the government’s intentions and determine how likely prosecutors want to go to trial.
