A tragic crash on I-55 in Logan County, midway between Bloomington and Springfield.
Two children are dead and two others have suffered serious injuries after a six vehicle pileup Sunday afternoon on Northbound I-55 near the Atlanta exit.
State Police investigators say the chain reaction crash was started by a semi driven by a Missouri man. The semi crashed into the back of a van driven by a Chicago man. That van then hit four other vehicles.
The children killed were in that van.
Their ages have not been released. The two other victims injured were airlifted from the scene.
The crash closed that stretch of the interstate for six hours.
