Elizabeth Cornes, 10, died on February 2007 from a 4-wheeled ATV accident. Elizabeth's neighbor found her on the ground unconscious and bleeding from her head, ears, nose and eyes after riding through fields in Louisiana. She had suffered no broken bones and the ATV had not flipped over; Elizabeth's mother Leslie Cornes suspects that Elizabeth and the neighbor were racing when Elizabeth lost control and hit her head on the metal rack in the rear of the vehicle. "We blame ourselves greatly as she should have never been on something as big and powerful as that," said Leslie Cornes. The American Academy of Pediatrics recommends that under no circumstances should children under the age of 16 operate ATVs due to "immature judgment and motor skills."
