OIG investigation leads to prison time, $2 million in restitution for four executives of a masonry firm who bribed an Amtrak employee

December 1, 2025

PHILADELPHIA — Khaled Dallo, an executive with a masonry restoration contractor hired by Amtrak for façade restoration and repair at 30th Street Station, was sentenced November 21, 2025, to two months in prison, one year of probation, 120 hours of community service, and was ordered to pay a $20,000 fine and joint restitution of more than $2 million for conspiracy to commit federal program bribery.

Dallo, a vice president at the masonry firm, was the last of four executives with the same firm to be sentenced in the bribery case. The executives at the firm, including the firm’s president and owner, conspired to bribe a former Amtrak project manager with approximately $323,686 worth of paid vacations, jewelry, cash, dinners, entertainment, transportation, and other items of value. In exchange, the former project manager approved over $52 million in additional change orders and contract modifications and provided the contractor with internal information about the project.

As a result of the years-long scheme, Amtrak was overbilled by approximately $2 million for the repair and restoration work. Federal funding supplied 90 percent of the money Amtrak used to pay the contractor for the project. Amtrak OIG initiated the investigation after a hotline tip alerted its agents to the scheme.

Other executives sentenced for their roles in the scheme include:

Mark Snedden, the contracting firm’s president, was sentenced October 1, 2025, to 90 months in prison, one year of supervised release, and a $250,000 fine.

Lee Maniatis, the firm’s Chief Operating Officer, was sentenced October 24, 2025, to 18 months in prison and three years of probation.

Donald Seefeldt, the firm’s senior executive vice president, was sentenced June 3, 2025, to 57 months in prison, one year of probation, 59 hours of community service, and was fined $50,000.

All four of the firm’s executives were also ordered to pay more than $2 million in joint restitution. The Federal Railroad Administration also suspended the four men and Snedden’s firm from participating in all federally funded procurement and non-procurement activities.

In addition to Amtrak’s Office of Inspector General, the case was investigated by the FBI and the U.S. Department of Transportation OIG. U.S. Attorney Jason Grenell prosecuted the case.
