In Kansas, a driver charged with leaving the scene of an accident faces both criminal and civil liability. You can face jail, fines, loss of license and a civil lawsuit. Considering the implications, I would suggest you contact an attorney. In the meantime, avoiding making statements or signing anything until a lawyer has spoken with you. I handle these types of cases. Feel free to email me at sean@roadlawyer.net if you want to discuss this further.
