The family of a 4-year-old left on a school bus for eight hours is outraged. Gavin Cook fell asleep on the way to school in Morrison on Monday.
After dropping off all the kids, the driver never did a final walk through on the bus before parking it for the day.
Inside the bus is where Gavin remained until he was found at the end of the school day.
His family says it never should have happened, especially after teachers realized Gavin wasn't in class Monday.
"They didn't make the call to see where he was and they noticed at 9:15 that he was missing" said Gavin's grandmother Teresa Cook.
The Morrison school system admits a huge mistake was made.
The superintendent Jay Vernon was the first to find Gavin and provided the pre-kindergartner with chips and water before taking him home.
Vernon says he isn't sure how or if the driver of the bus will be disciplined.
The Morrison school system is small, with teachers and even the superintendent himself working as bus drivers as well.
The Cooks say Gavin was traumatized by the experience. The family plans to take their complaint to the State Superintendent.
"I want to make sure this doesn't happen to anyone else," Teresa Cook said.
Gavin's mother says her son tried to get off the bus after waking up, but couldn't open the door. She says she will be driving him to class on Wednesday.
