Did you report you car stolen?
Did you tell the insurance company that you had been in an accident or did you tell them that the car had been stolen or loaned to someone else?
As far as a possible criminal charge, yes you could be charged with Leaving the scene of an accident, with property damage.
The maximum penalty for this is up to 60 days in jail and/or a fine of up to $500. It is a misdemeanor offense.
The police are most likely still investigating this, and if your license plate was on the car, it shouldn't take them too long to locate you, and unfortunately yes, pursue criminal charges.
My recommendation would be to retain a lawyer to assist you with this. If investigators contact you, you should be careful what you say and remember that anything you say can in fact be used as evidence against you in court.
