Unfortunately, a lot of theft crimes are the result of stupid decisions. But, of course, that doesn't do much to mitigate the crime. Whether you might get jail/prison time depends on the circumstances and the actual offense you are ultimately convicted of. The fact that they charged it as a felony tells you that jail or prison time is a distinct possibility. According to the WI statutes, a Class F felony is punishable by a fine of up to $25,000, imprisonment for up to 12 years and 6 months, or both. WI statute 939.50(3)(f). On the other hand, since you are not a repeat offender, there is no mandatory minimum and the court is authorized to impose probation instead. Thus, if convicted of this crime, your sentence could be anything from a fine and/or probation to 12 and half years in prison. The circumstances of the crime and the attitude of the sentencing judge are important, and without knowing that, no one here can guess the outcome. See a local criminal defense attorney for help. Facing a felony, you don't want to do this by yourself.
