John Mazzella is an Associate Managing Director in Kroll’s Business Intelligence and Investigations practice, based in the New York office. John is a veteran fraud investigator with over 25 years of experience in the U.S. Department of Justice (the DOJ) and the U.S. Department of Labor’s Office of Labor Racketeering. He has led many complex financial investigations involving a global cast of players and is an expert in the acquisition and analysis of data sourced from digital evidence, corporate and financial records, informants, and international fieldwork. John has testified numerous times in both state and federal court. His tenacity and dedication resulted in a number of successful prosecutions of financial frauds, cyber crimes, labor racketeering, public corruption, and international terrorism. Some of his cases also resulted in multimillion-dollar judgments.

Since joining Kroll in 2016, John has specialized in a wide range of financial investigations to include corporate frauds, FCPA violations, embezzlements, bankruptcies, and corporate monitorships. Notably, John has led an FCPA investigation which resulted in the filing of a federal lawsuit and criminal referral to the DOJ.    

John joined Kroll from the DOJ, where he spent almost two decades as a Senior Criminal Investigator for the U.S. Attorney’s office for the Eastern District of New York. For the majority of that time, John was a member of the FBI’s Joint Terrorism Task Force (JTTF) and, most recently, part of the FBI’s Cyber Crime Task Force. Many of John’s cases required years of coordinated effort with domestic and international law enforcement, intelligence, and military agencies. These complex investigations required the use of an exhaustive array of investigative strategies and meticulous gathering of evidence.

John also spent nearly 10 years as a Special Agent for the U.S. Department of Labor, Office of Labor Racketeering. In this role, he successfully investigated cases involving allegations of bribery, embezzlement, money laundering, kickbacks, investment fraud, organized crime, and public corruption. Many of these investigations were international in nature and involved sophisticated fraudulent schemes.

Over the course of his distinguished career, John has received several commendations and awards for outstanding achievement. He was also invited by the DOJ Office of Overseas Prosecutorial Development Assistance and Training (OPDAT) to help train foreign prosecutors and investigators in Nairobi, Kenya.

Professional Experience

The following is a brief list of representative federal investigations and prosecutions:

Asset Searches

Led an investigative team that was responsible for the conviction of multiple defendants for providing material support to the Liberation Tigers of Tamil Eelam (LTTE), a designated foreign terrorist organization. Among other crimes, the investigation uncovered that millions of dollars were raised for the LTTE and laundered through charitable front organizations. The charities were eventually added by the Office of Foreign Assets Control (OFAC) to the Specially Designated Nationals list as terrorist front organizations. All remaining funds in the charities were seized at the time of the designations.

Fraud

Acted as the case agent for an investigation and prosecution of over 30 defendants charged with more than $3 million worth of credit card fraud. Those charged included several travel agency executives who acted as collusive merchants in credit card “bust-out” schemes. All defendants pleaded guilty and shared the responsibility of a multimillion-dollar order of restitution.

Internal Investigations

Investigated and prosecuted several individuals involved in a sophisticated international investment kickback and embezzlement scheme related to a Teamsters Union pension fund, which defrauded the fund of over $8 million.

Financial Investigations

Case agent for an investigation and prosecution of defendants involved in an investment scheme to defraud numerous investors across several states of hundreds of thousands of dollars. The defendants included a managing director for a major bank, an attorney, and an independent investment advisor. The evidence uncovered over the course of the investigation helped lead to convictions for investment fraud and money laundering.

Fraud and Corruption Investigations

Investigated two union officials eventually convicted of embezzling millions of dollars from an employee benefit fund spanning a decade. The union officials were also charged with laundering the criminal proceeds from the embezzlement. In addition to periods of incarceration, the sentencing judge ordered a multimillion-dollar restitution against the defendants.
