Virginia Man Pleads Guilty to His Role in Government Contract Fraud

For Immediate Release
U.S. Attorney's Office, Western District of Texas

SAN ANTONIO – David Joseph Bolduc, Jr., 61, of Herndon, Virginia, pleaded guilty on October 12 to one count of conspiracy to commit wire fraud for his role in a government contract fraud scheme.   Bolduc and QuantaDyn bribed a government official to obtain confidential government information and secure government contracts. Consequently, the government overpaid for flight simulators and training services at the expense of the American taxpayer.

Court documents reflect that QuantaDyn Corporation, a software engineering company based in Virginia, and Bolduc paid Keith Alan Seguin, 56, a former civilian employee at Randolph Air Force Base in San Antonio, more than $2.3 million in bribes from 2007 to 2018 to obtain government contracts and government pricing information. As part of the fraudulent scheme, Bolduc, one of the owners of QuantaDyn, conspired with QuantaDyn; Karen Paulsen, 56, of Beavercreek, Ohio; John G. Hancock, 60, of Fairborn, Ohio; and Seguin, 56, of San Antonio, to defraud the United States by overcharging to offset the bribe payments and inflate profits for the benefit of Bolduc, QuantaDyn, and the prime contractor that employed Hancock and Paulsen. From 2007 to 2018, the conspirators fixed the contract award and pricing on Air Force and General Services Administration (GSA) contracts, which caused the United States to overpay for flight simulator technology and simulator services.

Bolduc is scheduled to be sentenced on January 9, 2023 and faces up to 20 years in prison. A federal district court judge will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors.

On September 15, 2020, QuantaDyn pleaded guilty to conspiracy to commit wire fraud and was sentenced to probation for five years, ordered to pay a $6.3 million fine and pay more than $37 million in restitution. In addition to the fines and restitution, QuantaDyn was ordered to pay a forfeiture money judgment in the amount of $22,834,526.31 and forfeit funds in corporate accounts totaling over $7 million.

On June 15, 2021, Seguin pleaded guilty to one count of conspiracy to commit wire fraud and one count of tax fraud and false statements. Seguin is set for sentencing on January 23, 2023 and faces up to 20 years in prison on the conspiracy charge and up to three years in prison for the tax fraud and false statement charge.

On March 1, 2022, Paulsen pleaded guilty to one count of conspiracy to defraud the United States. Paulsen is set for sentencing on January 23, 2023 and faces up to five years in prison.

On August 16, 2022 Hancock pleaded guilty to one count of conspiracy to commit wire fraud. Hancock is set for sentencing on November 14, 2022 and faces up to 20 years in prison.
