Kathleen Reilly, known as Kitty, pictured at her graduation, became the first female Nassau County police officer in 1966, and was the only female officer lost in the performance of duty, killed in an accident on Christmas night 1967. She was off-duty when she stopped to assist a stranded motorist on the Meadowbrook Parkway, where she was struck by a passing car. Legislation to change the inscription on all badges from "Patrolman" to "Police Officer" was put in motion after her death, but it took until 1981 before badges were changed.

The first Nassau County police patrolmen drove convertible Ford runabouts, above, and were forbidden to put the top up except in rain or snow. Patrolmen were also responsible for all vehicle maintenance.
