DELAWARE, Ohio (WTVN) -- The woman who admitted to causing a crash that killed a beloved teacher and coach will serve four-and-a-half years in prison.

Mary Kathryn Paul, 37, could have received six years behind bars for the death of Robert Lennon. The DeSales teacher and cross country coach was hit while riding his bicycle on Miller Paul Road last September. Paul didn't stop or call for help.

Paul was also ordered to have her drivers license revoked for life, and pay a $10,000 fine.

Many of Lennon's relatives and students spoke in court as the sentence was handed down, with some asking for the maximum sentence of six years be imposed.

"Two years before she hit another bicyclist, knocked him through a mailbox onto concrete. She had to know there was at least a possibility she hit another person. Yet, she drove on," said Lennon's brother, Robert.

Lennon's sister, Beth Kraft, expressed her displeasure in court as well.

"That's one of the most painful parts, just to leave a body there. My brother, he deserved so much better than that when he touched thousands of kids' lives, but he was just left to die."

Paul also apologized to the family and the court for her actions.
