I'm trying hard to figure out what they can do here.
As I stated before it seems it's much easier in Wisconsin to seal than it is in other states. Typically around the nation facts in a complaint can be sealed to protect an on-going investigation. But other than a few super controversial federal terrorism cases, I haven't seen actual charges sealed in a compliant before trial. That would amount to a secret trial and that's typically deemed unconstitutional in the US.
My sense is the charges we can see are the only charges there are at the moment and that something other than an actual charge is sealed.
Here's the info I could find, some of which is otherwise super interesting:
Judges seal 200 cases from public view (Sealing in lieu of expungement).
Wisconsin Court System - eFile/eCourts - Redaction
Wisconsin Legislature: 801.21
(Motions to seal, what records can be sealed and how to file one. Lots of interesting stuff here that might be relevant).
