A bowhunter figured the wolf for a hungry coyote and arrowed him. Then he discovered the animal's radio collar and an ear tag marked No. 18. The hunter turned the 80-pound canine over to the Missouri Department of Conservation, which traced the collar and tag to Michigan. Turns out No. 18 was a gray wolf that had been trapped and collared in July 1999 near Ironwood, on the Wisconsin border east of Duluth. Michigan wildlife officials monitored the juvenile wolf for nine months, then lost track of it. During that radio silence, No. 18 covered plenty of ground.
