Here in Maryland we have had several mountain lion sightings over the years. First the DNR said everyone was wrong they were mistakenly seeing bobcats or coyotes.
Then when video cameras started getting popular, they received at least 3 different videos of free roaming cougars in Maryland. One of the videos is even a black phase cougar. They said these animals were almost certainly escaped captives.
The last one was a few years ago when several people spotted a 6' cat in the area of Andrews AFB. Lots of deer in this area. It was discovered that it escaped from an enclosure. Never did hear what happened to that one.
