As an example of not being able to find someone:
Three years ago my wife was the victim of a low life who crashed into her and totalled her car. She didn't need medical attention. The low life driver didn't have a license, didn't have insurance and didn't own the vehicle. Supposedly he had borrowed the vehicle from someone out of state. The driver got taken to jail and I don't know what happened to him longer term. Our insurance took care of us except we had to pay the $1000 deductible. The insurance company people tried to find and make contact with the actual owner of the vehicle and were not able to do so. Some people are good at staying ahead of trouble.
