The Harlow Twins

1938, Evergreen Park, IL (outside Chicago). Billy and Stevie Harlow were riding in the front seat with their mother Tammie when their Ford sedan collided head on with a Chrysler. During the collision, the cars spun in such as a way as to impact two additional vehicles.

Tammie Harlow survived but the boys were ejected through the windshield and killed instantly. A crime scene photographer from the local paper took this shot as a crew of volunteers worked frantically to free John Downing, the driver of the Chrysler. It appears that little Billy and Stevie stuck around to watch. (Source)
