Tenino , Washington ( CNN ) -- Authorities in Alaska are examining two wolves to see if they are the animals that killed a jogger last week , said a wildlife biologist investigating the attack . The two gray wolves were tracked down Monday and shot to death from a helicopter near the town of Chignik Lake , Alaska , said wildlife biologist Lem Butler . The wolves are suspected of killing special-education teacher Candice Berner last week . Berner , 32 , was attacked while jogging near the town , authorities said . `` We had a systematic search , '' he said . `` These were the only two wolves we could find tracks for . '' The wolves appeared to be the same ones that left tracks at the scene of the attack , and they matched witnesses ' descriptions of the animals seen near Berner 's body , Butler said . Officials will conduct tests on the wolves ' carcasses to determine whether they killed Berner , Butler said . The carcasses will also be examined to see whether the animals were rabid or starving , or suffering from some condition that led them to attack a human , he said . The rare wolf attack shook Chignik Lake , population 105 . `` We see wolves a lot , '' said Johnny Lind , president of the Village Council . `` But we 've never had anything like this happen . '' The killing is thought to be only the second fatal wolf attack in North America in more than a century . In 2005 , a wolf pack killed a geology student in Saskatchewan , Canada . Wolves typically avoid human contact and do not threaten people , said John Blankenship , executive director of Wolf Haven . `` They are not human predators . It 's healthy to have awareness of them , for sure . But to be afraid of them is too strong an emotion , '' he said . Wolf Haven in Tenino educates the public about wolves and serves as a haven for about 50 rescued wolves , many of them once kept as pets .
