My Friend Got In A Car Accident In Texas

My friend got into a car accident involving multiple cars this past Saturday. After her written report of the accident was given to her by the cops she was taken by an ambulance to the hospital. The cops told her a tow truck was on the way to the scene because her truck was not able to start. She left the report on her truck, she went home after the hospital visit in pain. Sunday she is calling Dallas multiple times to find out where her truck is, they claim they don't have it (she lives in fort Worth with no transportation and works on weekends). Calls multiple towing companies to see who might have it, none claim to have it. Monday morning she goes and find her truck left on the scene with wheels missing, doors and all inside belongings stolen. The report of the accident is not in the Dallas system and they are claiming that she refused a tow truck. What can my friend do in this situation?
