School bus kills boy in St. Louis

According to a St. Louis Post-Dispatch article:

A 10-year-old boy apparently trying to cross a street was run over by the rear wheels of a turning school bus and killed Tuesday afternoon at Shaw Boulevard and 39th Street, St. Louis police said. . . .

Early indications were that the victim darted off the curb to cross the street before the bus had completed a right turn, authorities said. The child apparently ran into the rear right side of the bus and was run over by the right rear wheels, police said.

The victim was a fifth-grader at Sherman Elementary School, four blocks south of the scene. . . .

The accident happened about 3:30 p.m. The bus had been going east on Shaw and was turning right to go south on 39th. The boy and his younger brother were on Shaw walking east and attempting to cross 39th Street. The victim's brother, identified by the aunt as Dwayne Robinson, was not injured.

Relevant traffic law can be found here and here. Note the references to "unmarked crosswalk"; apparently this boy was waiting to cross the street at just such an unmarked crosswalk; the bus failed to yield to pedestrians waiting to cross in the crosswalk as required by law. Instead of stopping and letting the pedestrians cross, the bus continued with a right-hand turn and that is when the incident occurred.
