CLEVELAND (AP) — Police say an Ohio school bus driver sacrificed her life to save a 10-year-old girl during an evacuation drill outside a charter school.

A police spokesman says the vehicle rolled over the driver Tuesday morning after she saved a 10-year-old girl who was about to jump out of the emergency exit at the back of the bus. The driver was identified as 51-year-old Laura Zborowski of Akron.

The accident occurred around 8:10 a.m. when about 40 children were participating in the drill at Middlebury Academy in Akron. The girl was the last student to evacuate the bus when it began rolling backward. The driver threw the girl onto a lawn before being struck.

The other children witnessed the accident. Grief counselors have been sent to the school.
