Criminal Law Questions? Ask a Criminal Lawyer.
Dear JACUSTOMER - The only thing your husband can do is have a trial and defend himself. If there was no paint detected on his keys it would seem that it would be his word against the lady's as to what happened and that may net be enough to convict him. He definitely needs to have an attorney and if he can't afford an attorney the court will appoint one.
He should plead not guilty and ask the court for an attorney. It does no good to try to talk to the police or prosecutor once the charges have been filed so tell him to get a lawyer and plead not guilty.
