If your son is under the suspicion of causing a crime but no actual charges have been filed against hime concerning the incident involving him and his car, I suggest that it may be best to consult with a criminal defense attorney about the situation and let the attorney handle things from there.If no charges have been filed yet against your son for the damage claimed that he did and there is no damage to the vehicle he was driving in the locality of the bank where the damage to the bank happened, there is a good chance that no charges will be filed. Had law enforcement had proof that he caused the damage, a criminal action would most likely have been filed by now.
