The salesman's car had a parking brake, which was something new to Starkweather. While he attempted to drive away, the car stalled because the brake had not been released. He tried to restart the engine, and a passing motorist, geologist Joe Sprinkle, stopped to help. Starkweather threatened him with the rifle, and an altercation ensued. At that moment, Natrona County Sheriff's Deputy William Romer arrived on the scene. Fugate ran to him, yelling something to the effect of: "It's Starkweather! He's going to kill me!"
