When a Dodge Ram pickup collided with a Mercedes passenger van near Yellowstone National Park, seven people - all thought to have been tourists - suffered fatal injuries

Idaho State Police say a pickup truck that collided with a tour van near Yellowstone National Park last week, killing seven people, crossed the center line and hit the van.

Idaho troopers say they're still working with international authorities to notify next of kin following a fatal crash between a pickup truck and a passenger van carrying tourists Thursday evening.
