Tennessee theft charges are based on the dollar amount that was taken.
The more you steal equals more punishment. Now to the little quirk. Prosecutors can aggregate thefts under Tennessee Code Annotated 39-14-105(b)(1). Here is an example. One steals a thousand dollars in a day, which is a misdemeanor. Then, one steals a thousand dollars a day for a year from the same person. You just turned a misdemeanor into a Class A felony. A Class A felony carries 15-25 years in jail. A simple theft charge just turned into a nightmare.
In order to aggregate theft, the state must prove there was a common scheme, purpose, intent, or enterprise. Theft charges must be proven beyond a reasonable doubt even to the common scheme element. Prosecutors have great power to determine how to present these types of charges. I remember a line from Spiderman. “With great power comes great responsibility.”
