Prosecutors in central Nebraska have charged a 21-year-old woman and a 39-year-old man with incest after Grand Island police say the father and daughter had sex in September, according to court records.
Samantha H. Kershner and Travis Fieldgrove face incest charges in Hall and Adams counties, according to court records.
Grand Island police began investigating the relationship between the St. Paul residents on Sept. 18 after Kershner's mother alleged they were in an illegal relationship, according to an affidavit for their arrests.
Investigators believe Kershner didn't grow up with Fieldgrove and three years ago learned he was her father, police said in the affidavit.
Contacted by Grand Island police in September, Fieldgrove denied to investigators that he was Kershner's father.
But DNA testing completed Jan. 14 determined there was a 99.99 percent probability of his paternity, according to an arrest affidavit for the duo in Adams County.
They face incest charges there because Hastings police allege they married at the Adams County Courthouse in Hastings Oct. 1.
This is a rare case where two adults are charged with incest, which under Nebraska law includes both intermarrying and sexual relationships between parents and children.
Commonly prosecutors file incest charges against defendants accused of sex offenses against children.
Nebraska law also declares any marriages between people in an incestuous relationship "absolutely void."
A Hall County judge has ordered them not to contact each other while the case is pending.
The duo have not appeared in Adams County Court on charges there.
Both are being held at the Hall County jail on bond.
If convicted as charged, each faces up to eight years in prison.
