Robert Chiarappa didn't speak at his sentencing Tuesday. He pleaded guilty last month to grand larceny for a scheme involving $1.2 million in fake invoices for items supposedly ordered for dismantling the former Deutsche Bank building.
The now state-owned skyscraper was contaminated when the nearby twin towers collapsed.
Chiarappa was the purchasing agent for demolition contractor John Galt Corp. The firm was fired and charged with manslaughter after two firefighters died in a 2007 blaze at the building.
The company has denied responsibility for their deaths.
