A western Kansas police officer who crashed his patrol vehicle into a car, killing its driver, while responding to an emergency call was not using lights and sirens.

Vanessa Guzman drove into the path of the patrol vehicle, and the resulting collision rolled her car over a guardrail. She was ejected as the car rolled and died of her injuries.
