A former sixth-grade teacher in Cheyenne who pleaded no contest to charges she had sex with a 13-year-old boy has been sentenced to eight to 12 years in prison.
The Wyoming Tribune Eagle reports Anna Andersen, who taught at Freedom Elementary, was sentenced Monday. She previously pleaded no contest to second- and third-degree sexual abuse of a minor.
Andersen was arrested in March 2014.
Prosecutors say she and the boy had an ongoing relationship from 2012 to 2014 and a sexual relationship for two years. Prosecutors say the boy was prepared to testify and investigators had text messages and other evidence to support the charges.
