Henry Garfias, the son of a Mexican general, was elected Phoenix's first town marshal in 1881. Already famous for apprehending the stagecoach "ghost bandit" as a county deputy, Garfias (above, courtesy of Duran Lugo) was said to have shot dead several outlaws as marshal and brought order to Washington Street's Whiskey Row (16 saloons and four dance halls). Thus was born the Phoenix Police Department.
The department operated out of the old City Hall until it received a more modern space in the City-County Building in 1929. Call boxes were used throughout the city for officers to check in. Phoenix equipped its squad cars with radios in 1932. You can learn more about PPD's history from the Phoenix Police Museum, located in the 1929 Police Headquarters at 17 S. Second Avenue. My new novel, City of Dark Corners, is set in the Depression-era department.
The Phoenix Fire Department came from passage of a bond issue in 1886 to establish a volunteer fire service with modern equipment and an improved water supply. Still, two hose companies (one Anglo, one Hispanic) competed until Frank Czarnowski joined them together as the Phoenix Volunteer Fire Department in 1888. By 1922, it was a paid, full-time department.
