Narrow and tree-lined, Iris Street is used daily by residents of Robynwood subdivision to get to and from Alston Middle School.
Sidewalks are sparse in the neighborhood, forcing children to sometimes walk on the shoulder of the road.
Sometimes, they walk in the road itself.
On Thursday morning, police said, a woman drove her car into a group of them.
She told investigators after striking the four children that she wanted to knock the daylights out of them.
