A 21-year-old woman has been charged with incest after competing with her half-sister over who could have sex with their father first.
Samantha Kershner and her 39-year-old father Travis Fieldgrove were both arrested last week in Hastings, Nebraska after police received a tip about their sexual relationship.
Police said Kershner and Fieldgrove both admitted to having a romantic and sexual relationship even though they knew they were biologically related.
They got married in October - just one month after finding out police were investigating them.
They met for the first time three years ago when Kershner, then aged 17, told her mother she wanted to know who her father was.
Kershner and Fieldgrove met and maintained a father-daughter relationship for three years.
They told police they had sex for the first time in September last year. The pair would not reveal how their father-daughter relationship turned sexual.
According to charging documents, Kershner told police that she had a 'jealous competition' with her half-sister about who could have sex with their father first.
Kershner's mother notified police about their relationship in September.
Fieldgrove married his daughter the following month at the Adams County Courthouse after they found out they were being investigated for incest.
Marriage licensing requirements where they married state that both parties need to provide the full names of their parents before it can be approved.
Fieldgrove is not listed as Kershner's father on her birth certificate.
When they were questioned by police, Fieldgrove said he didn't believe Kershner was his daughter because his name wasn't listed on the certificate.
A paternity test that Fieldgrove and Kershner agreed to have in January found that there was a 99.999 percent probability that he was her father.
They were each charged with one count of incest and are both being held at Hall County Jail.
Fieldgrove's bond was set at $100,000, while Kershner is being held on a $20,000 bond.
They each face eight years in prison if convicted.
