Which Chief of KCFD is NOT listed when considering the last five Chiefs?

The identification of the Chief who is not included in the consideration of the last five Chiefs of the Kern County Fire Department is based on historical leadership records. In this context, Susan McKinney is the correct choice because her tenure, while significant, does not fall within the last five chief appointments. This indicates that the individuals who served in the role of Chief prior to her or after her are the ones making up the last five Chiefs, while she herself may belong to an earlier or different period in the department's leadership history. Understanding the chronological order of leadership is essential for accurately identifying current and past Chiefs, as well as appreciating the organizational structure and evolution of the KCFD over time.
