The New London Superior Court sentenced Jeremy Doe, 25, of Jasper, Florida, to 15 years in prison for robbing two banks.
In 2007, Doe held up both a Bank of America and People's United Bank in Connecticut.
During both robberies, he put a female teller in a choke hold and held a gun to her head.
Doe robbed the banks of a total of $116,000.
He's already serving a 22 year federal sentence for a bank robbery in Raleigh, North Carolina.
