FAQs

01.

What qualifies as a major federal drug case?

Major federal drug cases usually involve large-scale trafficking operations, multi-state or international distribution, conspiracy charges, and high-quantity drug seizures. These cases are often built over time by agencies like the DEA or FBI and may involve wiretaps, confidential sources, or financial tracking.
If the government suspects that you were part of an organized operation, even if you played a limited role, you may face serious charges with mandatory minimum sentencing guidelines.

02.

What should I do if I am being investigated but have not been charged yet?

You should speak with a criminal defense attorney immediately. Federal drug investigations often continue long before charges are filed, and agents gather extensive evidence during that time. Early legal intervention gives your attorney the chance to review what is happening and prepare your defense before an indictment.
In some cases, early involvement can lead to better negotiation options or even prevent formal charges altogether. Waiting until you are arrested puts you at a serious disadvantage.

03.

Can your law firm handle cases involving cartels or international drug organizations?

Yes. We have defended individuals charged as part of cartel-related cases and other international drug operations. Many of these clients were extradited from Mexico or named in multi-defendant indictments filed in federal courts across the U.S. We know how to approach high-level charges, especially those involving international coordination and conspiracy allegations. Our legal team understands the sensitivity of these cases and moves quickly to assess exposure, negotiate with prosecutors, and manage public risk.

04.

Do all major drug cases go to trial?

No. In fact, most do not. Federal prosecutors often build strong cases before ever filing charges. Trials carry significant risks, and prosecutors typically seek resolutions through negotiated agreements. Our focus is on protecting your future, which often means working toward a favorable deal.
However, if the case does proceed to trial, we are fully prepared. Our firm brings deep trial experience and federal courtroom knowledge to every case we handle. We always develop our strategy with both outcomes in mind.

05.

What role does conspiracy play in major drug cases?

Conspiracy is one of the most common charges in major drug cases. You do not need to handle drugs yourself to be charged. Simply being part of a plan, or taking part in actions that support the organization’s operations can trigger conspiracy charges. These are often backed by surveillance, intercepted messages, or statements made by cooperating witnesses.
Because conspiracy can involve a wide range of behavior, it is important to have an attorney who can review the government’s evidence, identify weak links, and push back on overstated allegations.

06.

Why is your law firm a strong choice for defending major federal drug cases?

We bring real federal experience to the table. Mr. Mosbacker served as a U.S. Attorney and led the Brownsville Division of the Southern District of Texas. He has tried over 150 felony jury trials and negotiated with federal prosecutors across the country. That background gives us a unique insight into how federal drug cases are built and how they can be resolved.
We understand the pressure our clients face, and we take a direct, hands-on approach to defending them. Prosecutors know our reputation, and that often leads to more productive conversations and stronger results.
