A U.S. State Department employee and her husband were indicted Thursday on charges stemming from a scheme to steer more than $60 million contracts to a company they controlled, federal prosecutors said.

Kathleen D. McGrade, 64, and Brian Collinsworth, 46, both of Fredericksburg, face a maximum of 20 years in prison if convicted.

The couple operated a Virginia company called Sterling Royale Group, while McGrade worked as a private contract employee for the state department, where she oversaw the awarding of contracts.

The couple concealed their marriage and McGrade's role in SRG, while using their money from the scheme to buy a 41-foot boat, home, penthouse condominium, Lexus automobile and other luxury items.

Prosecutors said SRG was paid $39 million before the scheme was discovered.
