Jon Jason Greco, a 41-year-old man from Minneapolis, was sentenced on Tuesday to 10 months in prison for lying to federal investigators as the government attempted to seize assets related to Trevor Cook's $194 million Ponzi scheme, Minnesota's U.S. Attorney's office said.

Greco was charged in March and admitted in July to lying to investigators about foreign currency and coins he had stored in a locker at the Mall of America, according to the U.S. Attorney's office.

He told the investigators that the money was his own, when he knew that it wasn't. According to prosecutors, the money came from Cook's multimillon-dollar fraud.

Cook pleaded guilty in April to federal criminal charges related to the operation of a foreign currency trading scam that defrauded more than 900 investors, and he is currently serving a 25-year prison sentence. As part of his plea agreement, Cook agreed to turn over the proceeds of the fraud.

The government wanted to seize the foreign currency and coins from the locker at the Mall of America, and according to the U.S. Attorney's office, Greco's lies kept federal officials from recovering about $6,000 in assets.

According to a report by the Star Tribune, Greco is a Minnesota National Guardsman and an Iraq War veteran. In addition to serving time in prison, Greco was ordered to serve three years of supervised release and pay $6,000 in restitution, the Minneapolis newspaper reported.

Greco's Tuesday court appearance-one that would have typically been a routine, half-hour hearing-was stretched to 90 minutes as Assistant U.S. Attorney Tracy Perzel, the prosecutor in the case, argued that Greco deserved at least a year in prison, the Star Tribune reported. Chief U.S. District Judge Michael Davis reportedly grew impatient and eventually stopped her. To read more about Tuesday's courtroom events via the Star Tribune, click here.
