ANCHORAGE, Alaska (AP) — The remains of an unidentified victim of recently deceased Alaska serial killer Robert Hansen were being exhumed from an Anchorage gravesite, 30 years after her killer led authorities to her body near a lake north of the city.

Hansen confessed to killing 17 women in the 1970s and early ‘80s, hunting victims down in the wilderness as if they were game. Hansen died Aug. 21 at age 75 while serving a 461-year sentence in Alaska.
