KANSAS CITY, Mo. (AP) — A 3-year-old boy is dead after breaking away from his father’s hand in downtown Kansas City, Missouri, running into traffic and being struck by a gas company truck.

The accident happened around 1:30 p.m. Wednesday. The boy was in critical condition when officers arrived, but died at a hospital. His name has not been released.

A preliminary investigation showed that the child and his father came out of a store on 11th Street when the child “broke away from his father’s hand” and ran between two parked vehicles into the street.

He was struck by a truck belonging to Spire, a company based in St. Louis.

Police say the truck driver stayed at the scene and cooperated with police.

An investigation continues.
