Aggravated assault is a criminal charge. You sister should file a complaint with the police. As part of adjudication of the criminal case, the court will order the assailant to compensate your sister for all the damages he caused. A criminal court's judge can award a much higher value to your sister's pain and suffering than a civil jury would. And she will not need a lawyer: District Attorney's office will prosecute the case. If she does not get fully compensated by the criminal court, your sister can bring a civil suit for assault and battery, and for personal injury, and for intentional infliction of emotional distress. With a criminal conviction of her assailant, it will be a relatively straightforward case. If the assailant does not get convicted by a criminal court, a civil suit will remain very much possible (remember O.J. Simpson case?). So, my advice is to talk to the police and the District Attorney, first.
