Sorry for having an opinion, but to me it looks very much like the "subject" runs like a man in a gorilla suit.

The "gait" is unsuited to a creature with the body mass implied by the body outline, even assuming a very heavy fur coat. (In US terms, it runs like a basketballer, and should move more like a fat fullback.)

Of course, I'll wait for the DNA analysis of the hairs undoubtedly left on the brush the "thing" ran through. And surely they scared the poop out of this wild and reclusive thing, so a "scat profile" will give a good indication of diet, providing an exceedingly reliable indication of where and how it feeds. Even a cursory "stakeout" of feeding grounds will certainly provide additional sightings, so further documentation (i.e. more pictures) should certainly be expected.

Or it could just crawl in the ATV that carried it and the camera to the woods, and go home and call a press conference.

(A doubter or two is necessary to keep the discussion going, isn't it?)
