ST. LOUIS (AP) — Five boys are recovering after a car struck the group while they were walking in the St. Louis area.

St. Louis County Police spokesman Officer Benjamin Granda says the crash happened Sunday afternoon. A Kia sedan struck the group of boys, who range in age from 9 to 13 years old, as they walked on a grassy berm near the roadway.

Police said it appears that the 57-year-old woman driving the car had a medical issue before the crash.

One of the boys suffered a serious injury and was in critical condition Sunday. The other boys suffered minor injuries.
