Well you need an adovocate here with your job to help your bosses start believing you - maybe a polygraph would help as far as the crime at Kohl's involving your plate, you say the plate was stolen and I assume that the person at/near Kohl's who got the plate number did not also I.D. your vehicle ?!? If that is the case you should have no fear of being implicated in the Kohl's crime.
However, if yu feel this is turning sour and you have some risk of prosecution, then hooking up with a good criminal atty early on is best.
They are not going to "Charge you" unless they have evidence that actually implicates you!
All the best,
Well, sounds like they are looking at you, doesn't it?!? So, what to do ... best advice is to hook up with a local criminal aty that you trust and get their advice and do not try to "fix" this on your own ...
