Man Eater?
Contrary to popular belief, wolves are not dangerous to people. The Superior National Forest of Minnesota has always been home for two hundred to four hundred wolves. Some nineteen million visitor-days have been logged in there, yet not a single soul has been a victim of wolf predation.
There are several cases of wolves in other areas of North America possibly attacking people. One involved a scientist trying to break up a fight between a wolf and his sled dogs; the man ended up with a torn arm when he tried to grab the wolf by the back of the neck. In Minnesota, a wolf apparently mistook a deer-scent-soaked hunter for a deer and knocked him over. When the wolf realized its mistake, it fled. There have been a few similar events.
If a single wolf, or a pack, wanted to kill someone, it could probably do so without trouble. When killing prey, wolves are swift and silent. Wolves, though, are so afraid of man that in one incident they wouldn't even cross over snowshoe tracks.
