Police in St. Louis plan to interview survivors, today, of a Friday morning fatal crash on the Martin Luther King Bridge linking Missouri with Illinois. Four people were killed in a head-on collision involving a truck and a van. Police want to determine why the van crossed the centerline. Four occupants of the van were killed in the accident. They were headed from the Illinois side of the Mississippi River to their jobs near Lambert Field. Three other occupants of the van were injured, as was the driver of the truck, who claims he tried to swerve to avoid the collision, but couldn’t get out of the way.
