THERMOPOLIS, Wyo. (AP) — Five people were killed and four others were injured when a vehicle returning to Colorado from a Boy Scout camp in northwest Wyoming veered into oncoming traffic and slammed head-on into a motor home, according to the Wyoming Highway Patrol.

A 3-year-old passenger in the motor home and all four people in the other vehicle were killed in the crash on Highway 120 in north-central Wyoming on Saturday morning.

The Honda Element was one of three vehicles taking a group of Boy Scouts back to the Colorado Springs, Colo., area. The two other vehicles transporting the Scouts were not involved in the crash.

The Highway Patrol declined to release any other information Sunday, including the names of the victims and the extent of the survivors' injuries.

Hot Springs County Sheriff Lou Falgoust told The Billings (Mont.) Gazette that the troop members were working toward their Eagle Scout badges and had been camping around an area known as Pahaska Teepee, near Yellowstone National Park.

Investigators are still trying to determine why the Honda crossed the center line.
