Police Harassing Me About An Accident My Adult Child Was In. What Is Going On?

My child, who lives the next state over, was in an accident in my state. They are not telling me much, except to say, its not a big deal and no one was hurt. Seems they may have left the scene. Over the last four days the police have come to my house, spoke to a neighbor, called me and my other adult child and last night came again to my house, knocked on the door, shined ligts in my house and sat outside for about an hour (I did not answer the door). When they called me, I answered. They told me they had childs liscense plate, address, and name. I told them only that "I live alone, that car is not associated with my address". Later that evening is when they came to my house. They have not tried to contact the child who was in the accident, or go to their address as far as we know. This morning I found tickets between my storm door and front door. Honestly, they blew away when I opened the door, but I did retreive them, but easily could have missed them.

What the hell is going on? They know the address and name of my child, why are they harassing me?

The adult child is contacting an attorney this morning, and again assured me that no real damage was done, and no one was hurt.
