CSI New Bedford: Case of the Stained Carpet

The carpets were replaced in the studios yesterday.  They are really nice, but there is just one problem.  The carpets were about 2 hours old when we started to notice that someone tracked their dirty feet onto the carpet and left some very mysterious footprints behind.  Fingers started pointing and blame was immediately being thrown around the room.  Alliances were broken.  Here's 60 seconds of video of us trying to identify the culprit.
