Maybe. But that sort of thing is expensive for a court case, especially when there is sufficient evidence for conviction already. The driver was convicted of vehicular homicide (max five years), and leaving the scene of an accident.

His mother was charged with obstruction-type charges, and her case hasn't been tried yet.
