Last I had heard, they were still looking for a Grizzly Bear, a Lion, and a Monkey.... which sounded to me like the lead-in to a joke, until I realized they were serious.
My first thought was an animal rights activist had set them loose. Unfortunately, guys like this preserve owner are a big reason why there are so many over-the-top activists... But it was the owner, himself.
I find it weird that a convicted felon could maintain the licenses to keep those animals, though, especially since he'd had citations for not maintaining them properly.
