It took nearly 28 years for authorities to unlock the identity of Wilma Nissen.
It may have taken just a day to find her daughter.
One day after announcing Nissen's identity, Lyon County Sheriff Blythe Bloemendaal said he is confident a woman who contacted him Friday afternoon is Nissen's daughter.
"I am floored," Bloemendaal said. "This is amazing."
Until this week the sheriff knew few details about a body that was discovered Oct. 4, 1978, in a roadside ditch near the West Lyon School, in Lyon County in northwestern Iowa.
The body wore white gogo boots and a gold friendship ring. Previously known as Jane Doe, Nissen was 23 when she was killed. She grew up in California and had run-ins with the law including a prostitution charge.
