Becci M. Hill, of Martinsville, was accused of having a sexual relationship with the 15-year-old, whom she had mentored at one point, according to authorities. She was a special-needs counselor with the Wayne Township school district in Indianapolis.

Hill was arrested in July after a police officer saw her and the teen engaging in sexual activity in a car on a rural road, according to the Marion County prosecutor's office. She was 31 at the time.

In addition to sentencing her to prison, a judge ordered Hill to serve three years of probation and register as a sex offender upon her release.
