LYONS, Neb. (AP) — Authorities say a piece of human skull found two years ago in northeast Nebraska is not from the body of a woman missing since 1995.

Burt County Attorney Dan Smith said DNA analysis showed the fragment didn’t belong to the body of 48-year-old Wanda Krumwiede. Krumwiede, of Lyons, disappeared shortly after filing for divorce to end her 25-year marriage to Wilhelm Krumwiede.

Wilhelm Krumwiede was charged with her murder but was twice acquitted. He died in 2003 at the age of 66.

Authorities say the fragment was uncovered in early November 2012 by a contractor digging on land near Lyons.
