NBC Dallas: A woman was struck and killed by a Dallas police officer as she crossed the street early Sunday morning.

The incident took place at about 3 a.m. as the officer was following an ambulance through the 9900-block of Bruton Road to a disturbance call on Oak Branch Lane.

The ambulance was operating with lights and sirens activated, but the officer was not. After the ambulance passed, 43-year-old Beverly Kirk stepped into the roadway and was fatally struck by the officer’s patrol car.

Officers at the scene told NBC 5 that they are not required to run lights and sirens when responding to disturbance calls.

However, in 2008, after 10-year-old Cole Berardi was struck and killed by a Dallas police officer responding to a disturbance call, then-Chief of Police David Kunkle required officers to use lights and sirens whenever they are driving over the speed limit.
