An officer was dispatched regarding an unknown white male walking around in the street and striking passing cars with a flag pole. The officer approached the male on foot who then attacked the officer and knocked her down. The male was able to wrap his arm around the officer’s neck and began choking her. The officer regained her stance and tazed the male with negative results. The male continued to charge the officer and ignored her commands to stop. After attempting to create distance, the officer, in fear for her life, discharged her duty weapon once at the suspect, striking and killing the suspect.
