What will happen to Casey Anthony if more evidence is found against her?

Casey Anthony was found not guilty of murder yesterday, a verdict that shocked even her, I believe. What could happen to her if more evidence is later found against her? Would she get death row? How long could she go to jail for the lying to the police charges?What’s going to happen to that lawyer? Is he going to make out like bandit?
I know, alot of questions. Sorry. I’m just still in shock that she’s innocent.
