Could this be the Florida Skunk ape? Not to sure but it was an escaped exotic that evaded capture for four years in an urban setting.
The monkey showed up in St. Petersburg in 2008 and nobody knew were he came from. He avoided all contact with humans until they started feeding them.
Finally, he fell for the oldest trick in the book. Bananas led him to a trap were a tranqullilzer gun got him.
Many believe the skunk ape is just an exotic in the wild. We wont know until something else is captured.
