Homeland Security Investigation Defense Lawyer
Homeland Security Investigations and DEA Investigations Defense Lawyer in New York City
When Homeland Security Investigations (HSI) or the Drug Enforcement Administration (DEA) targets you or your business, you are facing some of the most well-resourced and aggressive federal law enforcement agencies in the United States. These agencies operate with expansive investigative authority, sophisticated surveillance capabilities, and the full backing of the federal government. At Sosinsky Law, our Manhattan federal criminal defense lawyer has spent more than three decades defending individuals and organizations under investigation by HSI, the DEA, and other federal agencies in New York City and throughout the state.
Understanding Homeland Security Investigations (HSI) in New York
Homeland Security Investigations is the principal investigative arm of the U.S. Department of Homeland Security (DHS) and one of the largest federal law enforcement agencies in the country. HSI has broad jurisdiction over crimes that involve cross-border activity, national security threats, and violations of federal customs, trade, and immigration laws. In New York City, HSI maintains a major field office and conducts investigations in close coordination with federal prosecutors in both the Southern District of New York (SDNY) and the Eastern District of New York (EDNY).
HSI investigations in New York commonly target international narcotics trafficking and drug smuggling operations, human trafficking and forced labor networks, immigration fraud and document fraud schemes, customs fraud and trade-based money laundering, cybercrimes including dark web marketplace operations, and weapons trafficking and export control violations.
What makes HSI investigations particularly dangerous is the agency’s ability to leverage intelligence from across the DHS network, including Customs and Border Protection (CBP), Immigration and Customs Enforcement (ICE), and the Transportation Security Administration (TSA). This gives HSI an unusually broad investigative reach that can draw in individuals who may not realize they are targets until the investigation is well advanced.
DEA Investigations and Federal Drug Enforcement in New York City
The Drug Enforcement Administration is the primary federal agency responsible for enforcing controlled substances laws in the United States. In New York City, the DEA operates one of its largest and most active field divisions, conducting investigations that range from street-level drug distribution networks to international narcotics trafficking organizations.
DEA investigations in the New York area frequently involve large-scale drug trafficking conspiracies involving cocaine, heroin, fentanyl, and methamphetamine, prescription drug diversion and pharmaceutical fraud, money laundering tied to narcotics proceeds, and drug-related violent crime including allegations prosecuted under RICO statutes.
As a Manhattan drug crime lawyer, Fred Sosinsky has extensive experience defending clients targeted by DEA investigations at every level, from individuals caught up in wiretap-driven conspiracy cases to alleged leaders of major trafficking organizations.
How Federal Fraud Conspiracies Are Tied to HSI and DEA Investigations
One of the most significant and often overlooked aspects of HSI and DEA investigations is the role that federal fraud conspiracies play in these cases. Federal agencies do not limit their investigations to the underlying criminal conduct such as drug trafficking or immigration violations. They actively pursue the financial infrastructure that supports and conceals that conduct, and this is where federal fraud charges become a powerful weapon in the government’s arsenal.
Wire Fraud and Mail Fraud as Federal Tools
HSI and DEA investigators routinely work with federal prosecutors to layer wire fraud and mail fraud charges on top of the primary offenses under investigation. Under 18 U.S.C. Sections 1341 and 1343, the federal wire and mail fraud statutes are extraordinarily broad, covering any scheme to defraud that uses interstate communications or the postal system. In the context of HSI and DEA cases, these charges may target individuals who used banks, wire transfers, or electronic communications to facilitate drug trafficking or smuggling operations, businesses that submitted fraudulent invoices or customs declarations as part of trade-based money laundering, healthcare providers who engaged in billing fraud to launder narcotics proceeds, and individuals who created shell companies or fictitious identities to conceal criminal activity.
Conspiracy Charges and the Federal Conspiracy Statute
Federal conspiracy charges under 18 U.S.C. Section 371 and drug-specific conspiracy charges under 21 U.S.C. Section 846 are among the most common charges brought in HSI and DEA investigations. A federal conspiracy charge requires only that two or more people agreed to commit a federal offense and that at least one overt act was taken in furtherance of that agreement. This low threshold allows prosecutors to sweep in individuals who may have played peripheral roles in the alleged scheme.
In HSI fraud investigations, conspiracy charges are particularly dangerous because they allow prosecutors to attribute the statements and actions of co-conspirators to every member of the alleged conspiracy. This means that evidence you never saw and statements you never made can be used against you at trial. Prosecutors in the SDNY and EDNY are well practiced at using conspiracy law to expand the scope of an investigation well beyond the original targets, bringing in family members, business associates, and employees who may have had only tangential involvement.
Bank Fraud, Access Device Fraud, and Identity Theft
HSI and DEA investigations frequently uncover financial fraud schemes that accompany the primary criminal conduct. Bank fraud charges arise when suspects use false information to obtain funds from financial institutions, while access device fraud charges target the use of stolen or counterfeit credit cards, account numbers, and other access devices. These charges carry substantial federal penalties and are often layered on top of narcotics and immigration offenses to maximize sentencing exposure. In New York, where international banking and financial activity intersect with cross-border criminal enterprises, these fraud charges are among the most common additions to HSI and DEA indictments.
Government Contracting Fraud and Healthcare Fraud
HSI has developed specialized units focused on fraud against government programs, including government contracting fraud and healthcare fraud. These investigations often uncover schemes where individuals used federal contracts or healthcare billing as vehicles to launder money derived from drug trafficking or other criminal enterprises. When HSI identifies these connections, the resulting federal indictments can include fraud charges that carry penalties of 20 years or more per count, in addition to any penalties for the underlying narcotics or immigration offenses.
The Investigation Process: What to Expect
Both HSI and DEA investigations typically begin long before the target becomes aware they are under scrutiny. These agencies use court-authorized wiretaps and electronic surveillance, confidential informants and undercover operations, financial record analysis through subpoenas to banks and financial institutions, surveillance of physical locations and digital communications, and cooperation from foreign law enforcement through mutual legal assistance treaties.
If you have received a federal grand jury subpoena, been contacted by federal agents, or learned that associates have been arrested, you may already be in the crosshairs of an HSI or DEA investigation. The decisions you make in the earliest stages of an investigation can determine the outcome of your case.
Defense Strategies for HSI and DEA Cases in New York
Defending against HSI and DEA investigations requires an attorney who understands how these agencies build cases, what tools they use, and where their methods are vulnerable to challenge. At Sosinsky Law, our defense strategies include challenging the legality of wiretaps and electronic surveillance under Title III, moving to suppress evidence obtained through unlawful searches or seizures, attacking the credibility of cooperating witnesses and confidential informants, challenging the scope and application of conspiracy charges, and conducting independent investigations to uncover exculpatory evidence.
Our firm also provides aggressive federal sentencing advocacy for clients who face conviction, working with experts in forensic accounting, psychology, and other disciplines to present the strongest possible case for mitigation at sentencing.
Why New York City Is a Hub for HSI and DEA Enforcement
New York City’s position as a global financial center, major port of entry, and diverse metropolitan area makes it a primary focus for both HSI and DEA enforcement. The SDNY and EDNY are among the most active federal judicial districts in the country for narcotics and fraud prosecutions, and the federal prosecutors in these offices are experienced, aggressive, and well-resourced. The stakes in these cases are exceptionally high, with mandatory minimum sentences for drug offenses and sentencing guidelines that can produce decades-long prison terms for fraud convictions.
Whether you are under investigation in Manhattan, Brooklyn, Queens, or anywhere in the New York metropolitan area, Sosinsky Law provides the experienced, aggressive defense that these cases demand.
