Hope your daughters are ok, my 17yr old niece was t-boned by another 17yr old girl running a red light 2 weeks ago. It gave her a concussion from hitting the window and spinning 3 times before hitting another car in the opposite turn lane.
Did the girlfriend have insurance on the vehicle and if so, was the boyfriend an excluded driver? I run into that a lot, along with the uninsured illegal residents. I review every single auto collision report from 6 cities in the Metro daily (roughly 400 accidents a week) and it is an unfortunate, (1 in 4 uninsured) but a common trend. It would make many afraid to drive, if they read some of the reports that come in..
I usually get the District Attorney to add restitution on behalf of the Cities for damages to public property by uninsured motorists. However, it usually is going to take wage garnishment and tax refund interception to get anything, which we don't do, as it is too much for us to manage. It is rare for any of them to pay the restitution and it will just accumulate and be added to the court costs, the next time they get picked up. I usually turn these files back over to client legal and they send it to their collection agency, like the $16K traffic cabinet a guy hit and destroyed a few months ago and the girlfriends insurance company had him as an excluded driver. So now both of them are responsible for 16k plus interest and fees from the collection agency.
Depending on the county, you can check the court docket online, with the drivers name. You can get the District Attorney to file for restitution if there is no insurance. After that, yes you will need a lawyer to start and file garnishment proceedings.
