Detectives Division

The Detectives Division is PCAO’s law enforcement arm. The detectives are highly skilled, Arizona POST-certified, sworn peace officers.They handle thousands of requests each year to ensure prosecutors have the evidence needed for trial. In addition, they maintain our 88-CRIME operations and serve witnesses with subpoenas. They also handle dozens of special investigations and, from time to time, make direct arrests. PCAO detectives also participate as members of multi-agency task forces that include officers from federal, state and local law enforcement agencies.


The mission of PCAO’s 88-Crime program is to collect crime information effectively from anonymous callers and online visitors and channel the information to the appropriate law enforcement agency. Our program provides the community an opportunity to assist in the prevention of crime safely and confidentially. As an added incentive, callers and online visitors may be paid up to $2,500 for information leading to an arrest.
