DUNCAN, Okla. (AP) -- An Oklahoma woman who married her daughter has pleaded guilty to incest.
Court records show 46-year-old Patricia Spann of Duncan pleaded guilty Tuesday in exchange for a two year prison sentence.
Her daughter, 26-year-old Misty Spann, pleaded guilty in November in exchange for probation. However her plea was withdrawn when it was learned the type of probation she was given -- a deferred sentence -- is not allowed under state law.
Court records show the marriage was annulled in October at Misty Spann's request on grounds of fraud and illegality.
Patricia Spann has said she thought the marriage was legal because she lost custody of her daughter and two sons years ago and isn't listed on their birth certificates.
Prosecutors said Patricia Spann also married one of her sons in 2008. That marriage was annulled in 2010.
