Loren Coleman has posted an entry on the Cryptomundo website concerning the carcass found in the Big Black River in Mississippi roughly a week ago. You can read the post here but I can sum it up for you. Basically, there have been no statements from any officials in Mississippi and no follow up article in The Vicksburg Post. This deafening silence from all involved, along with the lack of any photos of the carcass, has led to wild speculation. The likeliest explanation is that the carcass is that of a black bear. However, the belief that this is a black bear is, at this time anyway, speculation as well.
More on this if I hear anything.
