In Tennessee, where you are Gollum, Theft offenses are broken down into severity by the amount of money involved. $5000 would be classified as Theft Over $1000. The next highest class is Theft Over $10,000. In Tennessee, Theft Over $1000 is a Class D Felony. D Felonies are generally punishable by 2-4 years incarceration for persons without extensive prior criminal records. D felonies are also probatable, meaning that the assumption made during sentencing is in favor of probation. Again, many other factors are brought into play, but in a general sense, had this event occurred in The Volunteer State, Wynona Ryder would likely receive a 2 year suspended sentence, 2 years probation, and have conditions such as restitution and community service work placed on her. Further, if she had zero prior convictions, she could qualify for a provision which would allow her to have this matter permanently expunged from her record if she successfully completes a term of probation.
Of course, she is in another state, but the laws will be surprisingly similar.
Long and short of it...she will get probation like anyone else.
