Samson “Sam” Enzer is a decorated former federal prosecutor and an accomplished trial lawyer, investigator, and problem-solver.  Sam focuses on the defense of companies and individuals in internal investigations, criminal and regulatory investigations and enforcement proceedings, and complex civil litigation, including securities class actions and derivative suits.  In his prior government and private practice roles, Sam handled multiple complex white collar matters involving parallel internal investigations by publicly traded financial institutions and other corporations, grand jury investigations by the Department of Justice (DOJ), regulatory investigations by enforcement authorities such as the Securities and Exchange Commission (SEC) and Commodity Futures Trading Commission (CFTC), and related criminal and civil litigations.  Sam is one of the leading cryptocurrency enforcement practitioners to come out of government service in recent years, and also has extensive experience with matters concerning securities and commodities trading, derivative products, market manipulation, corporate whistleblowers, asset forfeiture, and complex commercial disputes.        

Before joining Cahill, Sam served for eight years in the DOJ as an Assistant United States Attorney in the United States Attorney’s Office for the Southern District of New York (SDNY), where he rose to become a senior member of the SDNY Securities and Commodities Fraud Task Force.  As a federal prosecutor at SDNY, Sam conducted numerous jury trials in significant criminal cases, briefed and argued motions before federal district judges and appeals before the Second Circuit Court of Appeals, and led hundreds of grand jury investigations and prosecutions in a wide range of criminal cases, including several groundbreaking cryptocurrency-related prosecutions as well as matters involving corporate misconduct and whistleblowers, securities fraud, commodities fraud, cybercrime, insider trading, obstruction of justice, false statements to regulators, accounting fraud, market manipulation, money laundering, tax crimes, wire fraud, violations of the Racketeer Influenced and Corrupt Organizations Act (RICO), and murder-for-hire.  At SDNY, Sam worked closely with a variety of federal and state law enforcement agencies and regulators, including the Enforcement Divisions of the SEC and CFTC, as well as DOJ’s Fraud Section, Money Laundering and Asset Recovery Section and Tax Division.  Sam also handled significant asset forfeiture investigations and litigations for SDNY involving seizures of white collar crime proceeds, including the tracing and seizure of $33.4 million in cryptocurrency fraud proceeds and litigation over their forfeiture.         

During his tenure at SDNY, Sam was nominated for the United States Attorney General’s Distinguished Service Award in 2018 and received the Federal Law Enforcement Foundation’s Prosecutor of the Year Award in 2014.   

Sam’s noteworthy white collar matters at SDNY included:

  • Securing a jury verdict of guilty on all insider trading charges against a former investment banker in a difficult, high-profile retrial of what several news outlets dubbed the “silver platter” securities fraud case.
  • Leading the multi-year investigation and resulting criminal prosecution of McAfee antivirus software founder John D. McAfee on commodities fraud, securities fraud, wire fraud, and money laundering charges arising from McAfee’s deceptive cryptocurrency promotions and use of digital asset trading exchanges to launder fraud proceeds.
  • Leading the investigation and successful prosecution of the co-founders of a purported cryptocurrency debit card company called Centra Tech, Inc. in the first criminal securities fraud case in SDNY history based on an initial coin offering (ICO) of cryptocurrency tokens.

Prior to his government service at SDNY, Sam worked in private practice as a litigation associate for nearly four years at another prominent international law firm, where he represented publicly traded corporations and senior corporate executives in complex civil litigation and criminal and regulatory investigations.  Sam’s significant representations there included defending a major financial institution in a multi-billion dollar securities class action and parallel enforcement actions by the SEC and New York Attorney General’s Office, defending a former bank CEO in an internal investigation and parallel criminal and regulatory investigations by DOJ, the Office of Foreign Assets Control (OFAC), and banking regulators relating to anti-money laundering and OFAC compliance, and defending a former energy company COO in parallel DOJ and SEC investigations and a civil securities fraud class action arising from one of the largest marine oil spills in history.  

Before entering private practice, Sam clerked for United States District Judge Louis L. Stanton in the Southern District of New York from 2007 to 2009.  Sam graduated cum laude in 2007 from the University of Pennsylvania Law School, where he was a senior editor of the University of Pennsylvania Law Review.
