Mildred Hubertz was 59 when she went missing in 1968 from St. Ignatius, Mont., a small town 40 miles from Missoula.
In November 1982, hunters near Newport, Wash. — just across the North Idaho border and an almost four-hour drive from St. Ignatius — found a partial human skull in a remote wooded area north of the small Pend Oreille County community.
