Poor little guy, he has faded into the land of No-Where, of no news, no clues, and nothing to report. There has been nothing to indicate foul play, but this little guy did not go out and decide to explore. Somebody knows something, and it's how not one caring soul dares to speak up about who did what.
I still wonder if the little guy isn't lying a bit beyond the search parameters. I never did, still don't, think it beyond the realm of possibility that he got out somehow and walked away.
