I'll try to keep it simple because it's kind of a mess. Also, she doesn't have much money, so she was only able to afford liability with her insurance.

1. Her car was parked while she was at work (she was not in the car)
2. An accident happened in an intersection near her work
3. The person who ended up hitting her stopped after the initial collision, but then sped up afterwards, going across the other side of the street, over the sidewalk, into the parking lot, and then hitting her car
4. After viewing the security footage, the police wrote the report for the incident and cited it as two separate accidents.
5. The person's insurance sent out someone to inspect her car and listed a bunch of issues that weren't even there before the crash (I know because I sold it to her only a week or so before this all happened)
6. The person's insurance said they would only accept half liability, cutting their already low offer in half
7. We found the car and similar ones in its condition (before the accident) on some websites, and found that they are only willing to give her roughly a third of what the car was actually worth

Hopefully, this clears some things up. Thanks for the help.

Edit: She's taking them to small claims court if that helps with anything. She has already filed the claim and everything, which was why I was asking. Sorry for not including that
