Business Summary

The ICJIS Justice Web Interface (JWI) is a law enforcement and criminal justice portal developed and owned by Maricopa County. JWI does not store data; it provides access to over 265 legacy data sources along with many integrated data sources. JWI access to data sources is used to assemble related information and photos that can be rendered into an easy to read format for judges, probation officers, investigators, police officers and investigators.

JWI development is very closely tied to the Arizona Criminal Justice Information System (ACJIS) policies and benefits from an open dialogue between the state and the agencies, which are licensed to use the system. Now JWI has expanded its reach into interstate and federal resources and has become a universal application within Maricopa County for criminal justice information and research.

Technical Architecture

JWI is a unique, modular "open-sourced" design (depicted below) which is built expressly for use in city, county, state and federal law enforcement and criminal justice environments. On any given day, JWI is used to:

  • Gather and assess criminal histories for initial appearance, charging and pre sentence reports.
  • Register approximately 90% of the sex offenders in the state of Arizona (AZ).
  • Enter all state and national warrants issued within Maricopa County.
  • Enter and inquire against missing or unidentified persons in the NCIC database.
  • Register and inquire against stolen items such as guns, vehicles, boats, securities, and articles at the local and national level.
    • Identify subjects using AZ driver's license photos. Motor Vehicle Department Photo is used for tasks ranging from traffic stops to probationer identification to the prosecution of check fraud and identity theft.

Internal Usage

External Usage


JWI is enhanced regularly by internal Maricopa County departments as well as external agencies licensed to use and maintain the application. By agreement and practice, the majority of enhancements to JWI by outside entities are shared with internal Maricopa County users. This sharing of enhancements has served Maricopa County well, saving money, time and resources. Examples of shared enhancements:

  • Parsing and rendering of criminal history data from all 50 states
  • Graphical and Night Vision interface improvements
  • Mobile Device capabilities for JWI
  • Research for recidivism studies on multiple persons
  • Additional data sources and data rendering into CHD
