Project Overview

Glendale SPI efforts uncovered two related and persistent problems in the same target area in Glendale. The first involved repeat, career offenders who resided in or near the target area and committed crimes in the area, many of them violent, on a near daily basis. The second problem involved organized retail theft, both at convenience stores and large retail stores (malls, Wal-Mart, etc.). This problem was initially discovered through the targeted efforts at Circle K, in which a substantial percentage of the arrestees indicated that they committed the retail thefts for the purpose of selling the stolen merchandise rather than consuming it. The Glendale Police Department (GPD) and its ASU research partners sought to address repeat violent offenders and organized retail theft with evidence-based practices that reflected the spirit of the SPI.

Data Highlight

  • Using Social Network Analysis (SNA), the SPI team identified 31 suspects and over 100 associates residing at or near crime hot spots.
  • The Arrowhead Town Center location experienced a 27 percent reduction in calls for service.
  • The 6201 West Olive location experienced a more short-term 15 percent reduction in calls for service.
