Survivor speaks after fatal school bus crash in Ohio

At least three students, two parents and a teacher were killed in a fiery, five-vehicle wreck in Ohio on Tuesday. A charter bus carrying students and two semi-trucks collided on an interstate freeway. Two passenger vehicles were also involved in the crash that injured 18, officials said.

Tori Wilson was one of the students sitting at the back of the bus during the crash.

"If I wasn't able to get myself pulled out, I probably would've burned up in that bus," Wilson said.

The National Transportation Safety Board said it would investigate.
