The Use of GPS in the Supervision of Sex Offenders and Pretrial Defendants in Maricopa County

1:15 PM - 2:15 PM
Session Type: Workshop

Community supervision of the sex offender population has always been a controversial issue. Advancements in GPS monitoring of this population have served to ease the minds of those concerned, and recent legislative efforts have aimed at requiring even stronger supervision of the sex offender population, with electronic monitoring as a key component. The Maricopa County Pretrial Division, which already had more than 20 years of experience supervising pretrial defendants, initiated an innovative program three years ago enabling the court to order that GPS monitoring be installed before a defendants' release from custody. This enhanced level of monitoring provides the court and community at large with a higher level of confidence, as defendants are subject to immediate supervision upon their release from jail. This presentation will show you how Maricopa County uses GPS monitoring in its supervision of both the sex offender and pretrial population. It will include a review of monitoring of points, the design of inclusion and exclusion zones, and the various alerts with response times.
