Contact the Clerk of Court where the case was handled. The Clerk's office will be able to provide you with options to retrieve those documents, if possible. If you are only wanting the police report itself, you need to contact that police department and inquire about the procedures for obtaining a police report. There are costs involved with both procedures and some offices only allow for copies if you appear in person and make the copies yourself.
