"It wasn't until I found him that I just absolutely lost it and started crying and became hysterical," says Holly Johnson.
Tuesday, Johnson's young son missed the bus after school, and then started to walk home. It wasn't a short trip -- the distance between the 6-year-old's Queen Creek home and school is at least six miles.
The first grader missed the bus home. The doors back into the school were locked, so he started walking home by himself in 100 degree temperatures, not carrying any water, on a busy road.
You can understand why it would make any parent frantic.
Now, Kelton Murdock is at home having fun. But his mom Holly is still steamed.
She called his school, Jack Barnes Elementary, when he didn't arrive at home.
"So seeing a child that size walking down the road, you really think it is appropriate that your school buses just pass him?"
Kelton told us he wasn't scared, but he was thirsty and tired.
The plucky first grader walked by himself down busy Ellsworth road over two miles in the heat before his mom finally found him. She'd feared the worst.
"He had been wherever he was for 45 minutes. You go straight to he has been taken, who's got him, am I ever going to see him again, those kinds of things."
We were unable to get an on-camera interview with anybody from the Queen Creek Unified School district. But the superintendent did give us a statement: "We are aware of the situation where a student who missed the bus walked home... we are reviewing all procedures to prevent anything like this from happening again."
Meanwhile, Kelton is planning to do things differently too.
"So what are you going to do in the future if you miss the bus?" we asked.
"Bang on the doors!"
The school district is working on ways to keep kids safe going to and from school. But there's no room for error in a hot climate on busy streets.
