Three Colorado Boy Scouts and their scoutmaster on their way home from camp in Wyoming Saturday were killed after their car slammed into an RV head-on.

KDVR reports a three-year-old child in the RV also died in the crash, which occurred on Highway 120 in northwestern Wyoming.

Sgt. Stephen Townsend of the Wyoming Highway Patrol says four people were in the car when it crossed into the oncoming lane and slammed into the motor home. Four other passengers in the RV were rushed to the hospital, but authorities did not release any information on their conditions.

The Boy Scouts were reportedly returning to the Colorado Springs area from a camp in northwestern Wyoming. Two other vehicles transporting Scouts were not involved in the accident.
