The Maricopa County Voluntary Vehicle Repair and Retrofit Program has been suspended due to current economic circumstances that have resulted in a loss of funding for the Program. While the Program is unable to provide financial assistance for vehicle emission repairs, the Air Quality Department recommends that the necessary repair work be completed by ASE (Automotive Service Excellence) certified professionals at an Arizona Green Business repair facility. From its introduction in January 1999 through June 2009, the Voluntary Vehicle Repair and Retrofit Program had been funded by the State of Arizona. From July 2009 through November 2010, the program was funded by an Energy Efficiency and Conservation Block Grant from the U.S. Department of Energy. The Program provided monetary assistance to qualifying owners of older, high-emitting vehicles that had failed a required emissions test. Over the years, the program helped over 11,700 vehicles meet Arizona emissions standards, resulting in the reduction of over 2,100 tons of pollution.

In 2006, the Bureau of Justice Statistics awarded a State Justice Statistics grant to the Arizona Criminal Justice Commission’s Statistical Analysis Center to conduct research on homicide in Arizona. The Center, with assistance from local law enforcement officials, and researchers from the School of Criminology and Criminal Justice at Arizona State University, collected homicide data from the following sources: Supplemental Homicide Reports, law enforcement homicide case files, and autopsy reports. The purpose of this report is to provide a general description of the scope and nature of the homicide problem in Arizona. Specifically, this report examines the general characteristics of victims and offenders, the circumstances surrounding homicide incidents, temporal patterns when homicides occur, and the geographic characteristics where homicides took place.
