A Descriptive Study of Incompetent to Stand Trial and Non-Restorable Defendants in Pinal County Arizona

This thesis examines the demographic, clinical, and criminal characteristics and discharge dispositions of pre-trial defendants deemed incompetent to stand trial and non-restorable (IST/NR) in Pinal County Arizona. Currently, there is limited research on defendants who are deemed IST/NR and even less so on discharge dispositions. The study utilized comparative descriptive analysis of secondary data collected by the Pinal County Attorney Offices on IST/NR defendants and restored defendants. It employed chi-square analyses to compare key variables between defendant groups. The study found few variations in clinical, legal, and criminal characteristics observed by previous studies and no statistical differences amongst IST/NR and restored defendants. However, it found the re-offense rate of IST/NR defendants in Pinal County was considerably lower than the general prison population. Moreover, it identified a narrow use of civil commitment procedures and guardianship amongst the IST/NR defendants who have a mental illness. Implications for further research and policy for Pinal County and Arizona are made.
