The Nebraska State Patrol says DNA testing is planned to try to determine whether the skull is that of a woman missing since 1995.
The patrol says the skull was uncovered in early November by a contractor digging on land near Lyons. A forensic examination determined the skull was that of a middle-aged woman.
The Nebraska State Patrol is now gathering DNA evidence from the 1995 disappearance of 48-year-old Wanda Krumwiede for additional forensic examination and testing. Krumwiede 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.
