Gadsden County. My brother found a dead one in Leon about 2-3 years ago. Brought it to me for a positive ID. One was brought in dead to my office 15 or so years ago. Dogs had killed it. Owners of dogs wanted to know what it was.
I have spent a lot of time in the woods and it is the first live sighting for me too. Shows their range as coastal, but this one was a long ways from the coast. All 3 were.
We have weasels too, but never seen one, alive or dead.
They really just look like a miniature otter with fluffier tail (about the size of a really big ferret -solid brown- with a bigger tail) Seen lots of otters over the years.
