A former Chesterfield substitute teacher was sentenced to a year behind bars after reaching a plea agreement stemming from charges she had a sexual relationship with a student.

Anna Michelle Walters was originally facing two felony charges, but accepted a plea deal Thursday that reduced the crimes to misdemeanors.

It's a whole new world for Walters, 24, who once taught students. Now she's serving time and will soon have to register as a sex offender.

When she entered the courtroom, the former substitute teacher wouldn't deny or confirm her sexual relationship with an under-age student.
