The California mom who slept with her estranged teen son says she didn't commit incest - it was "genetic attraction."
Mistie Rebecca Atkinson, 32, was sentenced to four years and eight months in prison on Wednesday in Napa County Superior Court, according to the Napa Valley Register.
In May, Atkinson, of Lake County, Calif., pleaded no contest to incest, oral copulation, lewd contact with a minor and distribution of lewd material to a minor, the newspaper reports.
But in a letter to the court, Atkinson said she doesn't consider what she did as incest.
"I don't feel like I should have the charge of incest because there is something called genetic attraction that is a very powerful (phenomenon) that happens to 50 (percent) of people becoming reunited with a long-lost relative," she wrote.
