Why Am I Being Investigated by the…

…Federal Bureau of Investigation (FBI)?

The FBI is the primary federal law enforcement agency responsible for investigating cases involving computer crimes, internet crimes, public corruption, drug crimes, and acts of terrorism. The FBI regularly collaborates with additional federal and state law enforcement entities to prosecute individuals or organizations suspected of federal criminal activity.

…Office of Inspector General (OIG)?

The OIG operates as the law enforcement branch of the Department of Health and Human Services (HHS). Its primary responsibility is preserving the integrity of HHS initiatives as well as safeguarding the recipients of health and welfare programs. It mainly targets fraudulent healthcare providers suspected of Medicare, Medicaid, Tricare and Department of Labor regulatory infractions to accomplish these objectives.

…Internal Revenue Service (IRS)?

The IRS is perhaps the federal government’s most highly-publicized and largest entity. The IRS boasts a significant criminal enforcement division that actively pursues individuals and corporations committing tax fraud and associated crimes implicating the Internal Revenue Code (IRC). Cases involving accusations of money laundering, securities and Medicare fraud, and similar financial wrongdoings are often handled by the IRS in conjunction with other federal law enforcement groups.

…Drug Enforcement Administration (DEA)?

The DEA leads all federal investigations related to suspected federal drug crimes including manufacturing and distribution of controlled substances (cocaine, methamphetamine. and heroin, etc.) and prescription medications. The DEA’s current priority is diversion control and preventing the illegal distribution of opioids and prescription drugs.

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

Q: If convicted, what are the penalties for federal crimes?

Penalties vary in these types of cases, and there is no one-set rule. You could face a few years to decades in a federal penitentiary plus thousands in fines. To determine your exact risks, you would need to meet with an attorney from our law firm for a no-obligation case evaluation. Only then could we estimate your potential penalties if convicted.

Q: How do I know if I’m guilty of committing a federal crime?

There is no need to worry about guilt at this point. Even if you are indicted, that does not mean you are guilty. The prosecution carries the burden of proof in any criminal case. This means they must show that you are guilty beyond a reasonable doubt; that is what matters the most here. Right now, you have an opportunity to defend yourself from these charges and move on with your life.

Q: When will I be officially charged with a crime?

This question is hard to answer because it will depend on the agency investigating you and their progress in the investigation. Hiring a defense attorney as quickly as possible can help determine if you would even face charges. Often, an attorney can intervene before the grand jury is summoned, which means you might not be indicted at all. Our lawyers know whom to contact to find out what stage the investigation is in and the likelihood of a grand jury indictment. If your case is already headed toward indictment, we have an Emergency Defense Package ready to deploy so that we can get started on finding an ideal outcome.

Q: Can I negotiate a plea bargain with the federal government?

As with any criminal case, you can negotiate a plea deal. However, this is not something you should see as your sole option. Instead, work alongside a San Francisco federal criminal defense lawyer to find out what options you have, because your lawyer might get the case dropped without the need for bargaining anything.

Q: Can your firm represent me in San Francisco, California?

Absolutely. Our firm has a national presence, and we have represented clients in 21 states, including California’s major metropolitan areas. We conduct the initial consultation over the phone. Then our team is ready to deploy immediately to your location.
