The courtroom in Richland County was silent as former Ohio teacher Stefanie Erin Kellenberger, 41, learned her fate. Once a respected English instructor at Shelby Middle School, she now faces 15 years in prison for abusing a teenage girl she had known for years.
When the judge announced the sentence, Kellenberger showed no visible emotion. Moments later, deputies placed her in handcuffs and led her out of the courtroom to begin serving her time.
According to prosecutors, Kellenberger began grooming the victim when the child was just 13 years old. What began as attention and mentorship soon escalated into an illegal relationship after the girl turned 14.
The abuse took place in Kellenberger’s own home between February 2020 and October 2021, continuing until the victim reached 16, the legal age of consent in Ohio. The victim, who had been a babysitter for Kellenberger’s daughter, trusted her — a trust that prosecutors said was deeply and deliberately violated.
The Shelby City Schools district learned of the allegations in early 2024 when police notified Superintendent Michael Browning. Kellenberger was immediately placed on paid administrative leave. By September of that year, she was formally indicted, and she resigned from her position the following month.
In August 2025, Kellenberger pleaded guilty to 21 felony charges, including four counts of third-degree battery and 17 counts of unlawful conduct with a minor. Her plea deal set the stage for Monday’s sentencing, where the judge made it clear that while she may qualify for judicial release after 10 years, that possibility depends entirely on her behavior behind bars. “Don’t let anybody be confused,” Judge Brent Robinson said from the bench. “This is a 15-year prison sentence with the hope that you come back in 10 years and you’ve been a model inmate.”
Under the terms of her sentence, Kellenberger must also permanently surrender her teaching license, register as a Tier III offender for life, and re-register every 90 days following her release. She will also spend five years on parole under close supervision.
Before sentencing, Kellenberger addressed her victim through a written apology, acknowledging the devastating impact of her actions. “I know that during this time, you were just a child and I was an adult in a position of trust,” she wrote. “I’m responsible for everything that happened between us.
I put you in a position that no 14 or 15-year-old should ever have to be in. I’m so sorry for all of the emotional pain and hurt that I’ve caused you. I hope that my guilty pleas and this sentence will provide some degree of closure for you as you move on with your life.”
The letter may mark the end of the court proceedings, but for the victim — and for a community left stunned by the betrayal of one of its educators — the damage cannot be undone.
