Tampered evidence and recognizable handwriting.

Price was going through files to find some intel about a terrorist him and his task force were going after, but after a while he keeps finding out of place and tampered with other files all linked to you, his general. At first, he is a bit confused, but as he finds more and more, he gets concerned. And then he finds a file that had an entire page whited out and your handwriting all over the paper.
