I find it hard to believe that you could not have a public defender. If thats the case I think your 4th amendment rights were violated and if the miranda rights were not read; "If you can not afford an attorney one will be appointed to you", it will be thrown out, she was arresred right?
I agree with above get a lawyer! If her body and keys were not in the car or ignition there is no DWI, the court has to prove she was actually driving drunk on a public right of way, after the fact is irrelevent!
The dirty cop probable wont even show his face in court and it will be dismissed! The worst she would get is leaving the scene of an accident, if the cop even bothers to show up.
