The wolf killed by the Department of Natural Resources at a north-central Minnesota campground last month is the same wolf that attacked 16-year-old Noah Graham, according to DNA test results.
The Associated Press says the wolf's DNA matched samples taken from a comforter used when Noah was taken to the hospital.
The Solway, Minn. teenager said he was camping with friends on Aug. 24 at the West Winnie Campground on Lake Winnibigoshish when the wolf attacked and left him with a 4-inch gash in his scalp.
Noah was able to fend off the 75-pound male wolf by kicking it, sending the animal running back into the woods.
The wolf was trapped and killed by DNR officials a two days later.
The wolf tested negative for rabies, but a necropsy performed at the University of Minnesota showed the one-and-a-half-year-old wolf likely experienced a traumatic injury as a pup that developed into severe facial deformity, dental abnormalities and brain damage, the Associated Press reported.
The wolf's stomach contained only fish spines and scales. The DNR says the wolf was likely scavenging for food around the campground because it would have been hard for it to catch prey like a healthy wolf.
The incident is the first documented wild wolf attack on a human resulting in a significant injury in Minnesota.
