A post-mortem concluded that a rural US teacher was killed by animals, and the head of the Alaska State Troopers said wolves are the likely suspect.
However, Colonel Audie Holloway said the tests could not say for sure what animals are to blame.
Col Holloway said DNA tests might determine whether wolves are responsible for the death of 32-year-old Candice Berner, who had been teaching in Alaska only since August and was originally from Pennsylvania.
Ms Berner's body was found on Monday night about a mile outside Chignik Lake, a community on the Alaska Peninsula about 474 miles southwest of Anchorage.
The body had been dragged off the road to the village's lagoon and was surrounded by wolf tracks.Reuse content
