Probably a neurosurgeon.
My ex-SIL, a nurse of long standing, including a stint in the Israeli army, had a nasty fall, and when she woke up, there was a guy hovering over her. Groggily she asked him - Who are you? He answered, you had a blow to the head, I'm a neurosurgeon. To which she replied - neurosurgeons are assholes!!!

Get the security tapes, even if it's from the exit door to show who left after she arrived. It is hit and run, even if on private property. Also have her look for cars with damaged lights or fenders in the garage
