The teenage victim told police on March 13 that he had sex with Thao in the classroom where she taught about six weeks earlier.

She resigned in late February and allegedly told a social worker at the Regions Hospital mental health unit where she was being treated.

Thao agreed to plead guilty in Ramsey County District Court this week and will serve up to six months in prison before she is put on probation.

She will also have to undergo a psychosexual examination and register as a predatory offender. Her sentencing is scheduled for September 10. 

St Paul City School sent a letter to parents on May 10 explaining the alleged illicit sex was with a 17-year-old boy after school hours in an empty classroom.
