Oh yeah, humans are just fine... Oklahoma woman who married mother after two 'hit it off' pleads guilty to incest. An Oklahoma woman who married her biological mother in 2016 after they reunited and allegedly “hit it off” pleaded guilty to incest Tuesday. Misty Spann, 26, of Duncan, Okla., pleaded guilty in Stephens County District Court and under the deal was sentenced to 10 years of probation. Her mother, Patricia Ann Spann, 44, has pleaded not guilty to incest. Her court date was slated for January. She could face 10 years in prison if found guilty. Prosecutors said Patricia Spann also married one of her sons in 2008. The marriage was annulled in 2010 due to “incest,” The Associated Press reported. The mother said she thought the marriage to Misty was legal because she had lost custody of her daughter and two sons years ago and is not listed on their birth certificates.
