I really hope you find the resolution that you need to heal from this experience and move forward. Best wishes

Could be very expensive, as I’m sure you can imagine. Might also be difficult (not impossible) for the person to get the first hand data they need from other sources such as police, insurance investigators, etc, without a legal case and judicial involvement. FOIA requests of police records is an option though could take time. Good luck. Again, I’m sorry this is even something you have to feel concerned about.
