MARSHALL, Minn. (KARE) - A mother in Minnesota says her son's school left him alone at a museum in another state.
The 4-year-old was on a class field trip to South Dakota and the bus went home without him.
The museum is more than an hour away, and the boy's mother says her son was scared, as was she.
The school district has apologized.
"It's the worst nightmare I could have ever been in. I'm still in it," said Jacqueline Whylly.
"It happened as a result of processes and protocols not being followed. The process of counting students before they get on the bus and taking a subsequent head count when the students are on the bus wasn't followed," said Supt. Klint Willert of Marshall Public Schools.
Willert says the teacher is being disciplined and a meeting is scheduled for Thursday to go over head-count policy.
