There was a post back in 2017 where someone had pictures of the alleged Winged Demon up on Facebook, and the local KC news covered it. Here are the images from that post, so you can see what our own Sinister Sarah was out hunting. She braved being swept away by this thing, all while fending off frostbite! Thank you for your efforts, Sinister Sarah.
This reminds me of the show Lucifer when his wings pop out.
