An 84-year-old trust company operator in Florida was sentenced to four years in federal prison for orchestrating a Ponzi scheme whose victims included a widow who lost $750,000, according to prosecutors.

Larry A. Carr of Tampa, Fla., who on May 9 pleaded guilty to selling unregistered securities, was sentenced by U.S. District Court Judge Susan C. Bucklew, who also ordered Carr to pay more than $8 million in restitution, according to the U.S. Attorney’s Office for the Middle District of Florida.

The fraud resulted in losses to multiple victims in the amount of at least $8.2 million—money which Carr used for personal expenses, including a tithe to his church, according to Bucklew.

Carr, according to court documents, was the owner and president of Cita Trust N.A. Inc., Cita Trust Company N.A., Cita Trust Company Ltd., and Cita Trust Company A.G. (collectively called Cita Trust). One or more of the Cita Trust entities operated in Florida while others purported to be trusts or firms in Switzerland.

In 2015, Carr sold unregistered securities to a widow who paid for them with $400,000 from her late husband’s life insurance policy, according to prosecutors. She was told that $100,000 was deposited into a money market account earning 1.77% interest and that the remaining $300,000 was invested in a two-year Cita Trust investment note that earned 4.77% interest.

The widow made a second investment in the purported Cita Trust notes the same year, using $350,000 from the sale of a building related to her late husband’s business, prosecutors said.

Carr, however, did not invest the funds derived from the sale of his unregistered securities, prosecutors said. Rather, he used the money to make interest payments to earlier investors, to pay his employees’ salaries and to pay for personal expenses, including the lease payment for his luxury car, country club expenses, credit card bills, and the tithe to his church, the released noted.
