I think that even with a live specimen you would get people claiming it a hoax or explaining it away to their refined belief system of what it is.
Unless you criminally cage a humanoid which would be criminal because they would be a human kind. I see there are other creatures out there like monkey and ape that get mixed into big foot accounts, bears, animals not in their normal known habitat, some orangutans found. Not all just hoaxes, some new creatures do get found.
