It's an embezzlement case involving state funds and investigators say the people responsible did it all from a state prison.
Auditors say state inmates at LaGrange Prison stole about $7,000 worth of tax dollars.
An anonymous tip led investigators to look into the records of inmates working in the Kentucky Correctional Industries at the prison.
Auditors say from January of 2007 to January of 2008, 21 inmates got extra pay by modifying a spreadsheet program.
We're told an inmate with computer expertise had access to a computer as part of his job and he figured out how to change the software.
The so-called "mastermind" of the scheme has been moved to a private cell and we're told he no longer has access to a computer.
The Kentucky Correctional Industries is a self-supporting division of the Department of Corrections and employs about 175 inmates at LaGrange.
