Federal and white-collar criminal cases don’t necessarily follow the same path as other criminal cases. You might first learn of the case from contact with a federal agency, which may request records or an interview before they arrest or indict you.
Federal cases usually involve investigations by agencies such as the FBI, IRS, DEA, or the U.S. Department of Justice. All federal agencies have broad authority to gather information and build cases before they file charges. They may not tell you whether you’re a witness, a subject, or a target.
White-collar cases (whether state or federal charges) typically focus on alleged financial, regulatory, or professional misconduct rather than physical harm or contraband. Depending on the conduct and where it occurred, charges may be filed in federal court, state court, or both. Federal courts have jurisdiction over offenses defined under federal law, while state courts prosecute state violations. These cases may use the same set of facts. Therefore, it’s wise to work with an attorney who can handle both federal and state charges. In either case, Halloran Law Offices is ready to help.
Federal and white-collar cases usually involve long investigations and detailed charging decisions, not snap judgments. Attorney Halloran has represented clients charged with white-collar and federal criminal offenses including, but not limited to:
Fraud cases often argue that communications or transactions were misleading or deceptive. Federal prosecutors frequently rely on wire fraud and mail fraud statutes, which can apply broadly to emails, phone calls, and mailed documents connected to a crime. These cases usually hinge on intent.
Healthcare fraud typically involves billing and reimbursement practices, along with alleged misrepresentations to government programs. These cases involve complex regulations and industry standards, often revolving around how practices code their services.
Tax matters can begin as civil audits and later turn criminal. Cases can include evasion, false statements, or failures to file or pay. This is usually based on financial records and communications rather than a single transaction or tax filing.
Identity-related charges involve personal or financial information used without authorization. Aggravated identity theft may involve mandatory penalties when tied to certain underlying offenses, which can significantly affect the potential sentence.
These cases typically involve public officials and government-funded programs. The government may claim that you exchanged payments or benefits for influence or favorable treatment, even if the facts are weak and the relationships are longstanding.
Money laundering allegations typically revolve around how someone moved funds, not just their origin. You may be at risk for asset forfeiture, sometimes before a case is resolved. This can put your property and accounts at risk while your case is still pending.
Federal and white-collar cases are usually built over time and typically involve reams of evidence. Attorney Halloran’s defense strategy starts by stepping back and reviewing their investigation techniques, rather than accepting the government’s version of events.
Attorney Halloran starts with how law enforcement obtained their evidence. Search warrants, subpoenas, and data seizures all have legal boundaries. Part of any defense is determining whether investigators followed the rules and whether they can legally use that evidence in court. For example:
White-collar charges also depend heavily on intent and knowledge. Many statutes require the government to prove that you knowingly and intentionally engaged in misconduct, not simply that a transaction or statement turned out to be problematic. Context and the full record often tell a more accurate story than isolated documents.
When appropriate, Attorney Halloran’s early motion practice can narrow the case before it reaches a jury. Motions challenge whether evidence is admissible, how the prosecution worded or chose their charges, or the legal theory the government relies upon. This limits what the government is allowed to present and influences how the case proceeds.
Many cases can be resolved before trial, and Attorney Halloran will fight to get the best possible outcome. He approaches plea discussions with a clear-eyed view of the evidence and the risks on both sides. Halloran Law Offices fights to get the best possible outcome for every client, whether that’s acquittal, dismissal, or reduced charges.
If your case goes to trial, we’ll be ready. Halloran Law Offices approaches every case as if it’s going in front of a jury. That work typically includes:
