My question involves criminal law for the state of: Illinois
I'm currently working on a crime mystery novel, which takes place in Chicago, Illinois. In my book, there's a situation that happened years ago where a character was involved in a bar fight. The character comes from a very influential family. Due to the fight, the other party involved became paralyzed and died a year later from his injuries. There were witnesses that stated the other party started the fight. My character was only defending himself. Here are my questions:
1) I'm assuming this is considered Aggravated Assault, which is a felony. Can the prosecution drop the charges due to self-defense?
2) If the charges are dropped, is there still a criminal record of the occurrence?
3) If there is still a criminal record, can the record be expunged?
4) Can a civil case be brought against my character?
Thanks for any and all information.
