At least one person is dead and five others seriously injured after an 18-wheeler collided with a van this morning.  The van was carrying four kids and two staff members of the Kemmerer Village, a child care agency in Assumption.  One of the staff members was killed.

The semi-driver wasn't injured.  It happened at an unmarked intersection at county roads 800 North and 2500 East in Christian County.  

Christian County Sheriff Bruce Kettelkamp says the semi was carrying a load of rocks and was turning into a company that makes asphalt.  He says they're reconstructing the crash scene to determine what happened.  At this point, he urges all drivers to come to a complete stop at an intersection.
