The analysis showed that money from a restricted detention fund which could legally be used only to pay for jail items, such as food, detention officers' salaries, and equipment, was used to pay employees to patrol Maricopa County. The analysis also showed that many sheriff's office employees, whose salaries were paid from the restricted detention fund, were working job assignments different from those recorded in their personnel records. Arpaio's office kept a separate set of personnel books detailing actual work assignments, different from information kept in the county's official human resources records.
