Reducing case delay could reduce the average daily jail population by 450. The single largest driver of the jail population is the length of time people are held pretrial. Today, the average length of stay for individuals facing violent felony charges is 111 days, and for those facing homicide charges 390 days. For the last two years, an initiative called Justice Reboot has brought together leadership from every part of the criminal justice system to identify and resolve causes of delay.
