Your best bet if having your attorney advance the case because of that. If you don't show up, a bench warrant will be issued for you. Also, if you are out on bail, that may mean the bail bonds men will come after you.
If for some reason it does not get charges as a felony, than you can have an attorney make the appearance for you.
Please feel free to call me with any questions, I would be glad to answer them for you.
