What kind of fines/ jail time would a person get for destruction of personal property?

It depends on how the prosecutor charges it. If they charge her with malicious desstruction of property as a misdemeanor, the maximum she will face is 180 days and/or $1000 fine (and most likely some level of restitution for the damage she caused). If it is charged as a felony, the maximum is 10 years and/or $5,000 fine (also with restitution). Whether it is charged as a felony or misdemeanor is at the discretion of the U.S. Attorneys office, which considers the value of the property itself. If they do charge it as a misdemeanor, there are several alternate options that might be available to her so that she can avoid any criminal record (especially if she is a first time offender). However, some of these options require some level of consent with the victim. If she is charged, be sure to hire a lawyer who is willing to look into and discuss these options with you, rather than automtically trying to resolve the case by having her plead guilty at the first chance available. In my opinion, a lawyer who knows these options and tries to use them for his or her client's advantage seperates the good lawyers from the great ones.
