There have been reports of hyenas trotting along the banks of the Mississippi river.
Sceptics say it appears to be a dog. Only DNA testing can confirm whether or not it is a hyena.
With its sloping back and apparently stumped tail (although hyenas only look like they have stumped tails as they don't) the man who captured this sighting, Tim McCary, handed it in in speculation of it being a hyena.
Now, many sightings have died out due to folklore. Mr McCary's "hyena" is one of few American hyena sightings.
