I thought about calling companies individually, but really don't have time for that. If I have to, I'd rather leave it to GEICO to do what they do. I just received the Police Report, which had no, additional identifiable info beyond the plate. The PO is off today, so I'll be checking in tomorrow and we'll see if he'll share (my guess is no and that nobody there will provide it).
@AJK, did you have anything specific in mind when you said file a request? An actual form. Do I need any additional standing, or need to reference something particular? Thanks.
