A Polk County judge Thursday sentenced an ex-Central Florida Aerospace Academy teacher to 22 years in prison.
30 year old Jennifer Fichter pleaded guilty to have sex with a 17 year old student.
She admitted to having sex with up to three underage students from the school where she was an English teacher.
Fichter still faces charges in Hillsborough County because she allegedly had sex with at least one of the students across county lines.
