There is actually an incredibly small number (~10) of fully wild red wolves still in the Carolinas (I think it's the only wild population left, but I'm not sure), as well as about 100 in North Carolina's "Red Wolf Recovery Area" as part of a reintroduction program. Unfortunately, coyotes have moved in during the wolves' absence, which makes it harder for the wolves to return to the wild, and has led to breeding between the two species when reintroduction is tried. We did exterminate our grey wolf population though, I think the last confirmed sightings were in the 20s or 30s? You do get the occasional hiker or whatever claiming to have seen one still though. We also don't have wild mustangs though, so you won't see red wolves hunting them even if they get their numbers back (though we do have plenty of horses, which do NOT like wolves or coyotes).
