Yes, there is. I am not clear about your particular charges as the information is somewhat contrary. An infraction is less than a misdemeanor, yet it showed up in a volunteer background check. Your concern is warranted. Contact any Avvo or other criminal attorney and discuss it.
I have many more questions than answers at the moment. Yes, of course, counsel in the Inland Empire can help you. I understand that you must be somewhat frantic but specifics as to charges, the circumstances initiating the investigation and many other facts need to be known. Contact a criminal attorney out your way or maybe in Victorville. The initial consult is usually free . Take all documents you have with you to the consult and do it now. I wish you well.
