TAUNTON — A young boy from Taunton was left on a school bus Monday, and now his parents want to know why it went unnoticed for several hours.

ABC6 is reporting that three-year-old Xavier Ebersold was marked present Monday morning at Triumph Head Start, despite never actually arriving at the school. He was found several hours later still in the school bus, all alone, six miles away from the school.

The executive director of the school says all employees involved in the incident have been removed from their positions, and an internal investigation is underway.
