A car returning to Colorado from a Boy Scout camp veered into an oncoming lane and slammed head-on into a motor home, killing five people and injuring four others, the Wyoming Highway Patrol said.

All four people in the vehicle and a 3-year-old passenger in the motor home were killed in the collision on Highway 120 in northcentral Wyoming, Sgt. Stephen Townsend said.

The other four occupants of the motor home were injured in the crash around 10 a.m. MDT Saturday in Hot Springs County, but their conditions were not immediately available.

The person believed to be the driver was flown to a Billings, Mont., hospital, while the other three were rushed to a Thermopolis hospital, about 35 miles south of the crash site, Townsend said in a news release.

The Honda Element was one of three vehicles carrying a group of Boy Scouts back to the Colorado Springs, Colo., area after spending time at a Scout camp in northwest Wyoming, he said. The other two vehicles were not involved in the crash.

No names or other information about the dead and injured were released, and patrol spokesmen couldn't be reached late Saturday night for further details.

Hot Springs County Sheriff Lou Falgoust told The Billings (Mont.) Gazette that the Scout group had been camping around an area known as Pahaska Teepee.

"The driver of the Honda was around 64 years old," Falgoust said. "They were with a convoy of at least two other vehicles that had made the trip. One was 200 yards ahead and the other was the same distance behind when the accident happened."

The patrol said crash investigators were trying to determine why the car crossed into the oncoming lane.

The motor home had been towing a passenger car.
