Former BizJet Sales Manager Pleads Guilty to Foreign Bribery

Jald Jensen, 73, of Panama City, and previously of Van Nuys, California, a former sales manager of BizJet International Sales and Support Inc. (BizJet), pleaded guilty today for his role in connection with a scheme to pay bribes to government officials in Latin America to secure business for BizJet. 

“This defendant and his co-conspirators put profits above ethics and fair competition,” said Assistant Attorney General A. Tysen Duva of the Justice Department’s Criminal Division. “Mr. Jensen’s arrest, extradition, and guilty plea marks the final conviction in this long-running case. We will continue to enforce the Foreign Corrupt Practices Act by aggressively pursuing those who use bribery and corruption to gain an unfair advantage in international business.”

 “Today’s conviction underscores our commitment to accountability,” said U.S. Attorney Christopher J. Nassar for the Northern District of Oklahoma. “The defendant was returned to the United States to face charges stemming from a 2012 indictment, which alleged his role in a scheme to pay bribes to government officials in Latin America while serving as a sales manager for BizJet. We thank our law enforcement partners whose coordinated efforts made this extradition possible.”

“Today, Jensen finally faces justice for his yearslong scheme to bribe foreign government officials to win business for BizJet,” said Assistant Director in Charge Darren Cox of the FBI Washington Field Office. “His plea reflects the FBI’s long memory and global reach. We remain steadfast in our commitment to holding corporations and individuals accountable for international corruption.”

According to court documents, between 2004 and 2010, Jensen was a regional sales manager for BizJet, the U.S.-based subsidiary of Lufthansa Technik AG, which provides aircraft maintenance, repair, and overhaul services. During that time, BizJet provided services to customers in Latin America, Mexico, and Panama, including services to the air fleet for the Mexican President, the Mexico Federal Police, the Governor of the Mexican State of Sinaloa, and the Panama Aviation Authority. Jensen’s responsibilities as a BizJet regional sales manager included obtaining business from new customers and maintaining and increasing business with existing customers.

In his role as a sales manager, Jensen bribed foreign officials with authority and influence over contract awards and conspired with others to unlawfully direct business to BizJet. Jensen then conspired with others to conceal and funnel money to the foreign officials from various bank accounts throughout the United States, including through Jensen’s shell company, Avionica International & Associates Inc. 

In 2012, BizJet entered a deferred prosecution agreement and paid a criminal penalty of $11.8 million. Between 2012 and 2013, three of Jensen’s co-conspirators pleaded guilty to their roles in their schemes: Bernd Kowalewski, former President and Chief Executive Officer, Peter Dubois, former Vice President of Sales and Marketing, and Neal Uhl, former Vice President of Finance.

Jensen was extradited from Panama to the United States in September 2026. He pleaded guilty to conspiracy to violate the Foreign Corrupt Practices Act (FCPA). The Court will schedule sentencing for a date in 2027, and Jensen and faces a maximum penalty of five years in prison. A federal district court judge will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors.

The FBI’s Washington Field Office, International Corruption Unit, is investigating the case. The Justice Department’s Office of International Affairs secured Jensen’s arrest and extradition from Panama. 

Assistant U.S. Attorney David Whipple for the Northern District of Oklahoma, and Assistant Chief William Schurmann and Trial Attorney Joel Crespo of the Criminal Division’s White Collar and Corporate Enforcement Section are prosecuting the case.

The owner of a Texas construction company was sentenced today to 30 months in prison for obstructing the IRS’s efforts to collect unpaid employment taxes on behalf of the business he owned and operated.

According to court documents and statements made in court, David Stone willfully failed to pay over employment taxes he had collected on behalf of the employees of Engineered Metals Company, a roofing, siding and sheet metal business that he owned and operated. As a result of his willful failure to pay over these employment taxes, the IRS began collection proceedings against him. Knowing the IRS was attempting to collect this tax delinquency, Stone stopped filing individual income tax returns and used business accounts to pay personal expenses, such as child support and alimony, to keep funds out of his own hands and conceal his income from the IRS. Stone’s obstructive actions persisted from 2013 through 2024 and caused a total tax loss to the United States of approximately $1.4 million.

Stone previously pleaded guilty to one count of corruptly endeavoring to obstruct the due administration of the internal revenue laws.

In addition to the term of imprisonment, Stone was ordered to serve one year of supervised release and to pay approximately $1,384,766 in restitution to the United States.

Assistant Attorney General Colin McDonald of the Justice Department’s National Fraud Enforcement Division and U.S. Attorney Justin Simmons of the Western District of Texas made the announcement.

Wenshen Xu, 52, a Honduras-based Chinese national extradited from Guatemala, was sentenced today to 12 years in prison, five years of supervised release, and a $22 million money judgement for conspiring to import cocaine into the United States, conspiring to launder money derived from drug trafficking, and to providing material support to a designated Foreign Terrorist Organization, specifically the Cartel de Jalisco Nueva Generacion (CJNG).

“This defendant conspired to help international drug trafficking organizations bring illegal drugs into the United States and tens of millions of dollars in dirty money out of the United States,” said Assistant Attorney General A. Tysen Duva of the Justice Department’s Criminal Division. “Every case the Justice Department prosecutes as part of the Homeland Security Task Force to dismantle transnational criminal organizations and identify money launderers that prop up designated terrorist organizations makes America safer. Alongside DEA and our law enforcement partners, we will continue to put those who fuel the international drug trade and exploit the United States behind bars.”

“We are determined to stop the transnational criminal organizations that flood our streets with drugs and stem the tide of money that fuels their violence,” said First Assistant U.S. Attorney Theophani K. Stamos for the Eastern District of Virginia. “The Eastern District of Virginia is resolute in our pursuit of anyone content to profit from misery and suffering of others. Together with the DEA and all our law enforcement partners, we will ensure that these narco-terrorists cannot hide from justice.”

“This sentencing highlights the complexity of narco-terrorism and the threat it poses to our nation’s security,” said Special Agent in Charge Dustin Gillespie of the Drug Enforcement Administration (DEA) Special Operations Division. “Transnational criminal organizations operate without regard for borders, but they cannot outrun justice. With our global reach and international infrastructure, DEA is uniquely positioned to dismantle these illicit operations. We will continue to connect the dots, follow the money, and decisively shut down anyone who attempts to traffic poison into our communities — no matter where in the world they operate.”

According to court documents, Xu used a transportation network and contacts in Latin America to smuggle multi-kilogram loads of cocaine into the United States. Xu’s transportation network included access to airstrips, airports, armored cars, couriers, and associates. Xu was arrested in Guatemala, at the request of the United States, on July 17, 2025, after he and others agreed to arrange and facilitate the transportation of a multi-kilogram load of cocaine out of Cali, Colombia, on behalf of an individual who claimed to represent the CJNG. From in or around November 2023 until Xu’s arrest, Xu and his co-conspirators imported over 450 kilograms of cocaine into the United States and coordinated the laundering of over $22 million dollars from the sale of cocaine and fentanyl by drug trafficking organizations. This money laundering network used a variety of concealment methods, including cryptocurrency money transfers, trade-based money laundering, and encrypted communications platforms.
