The goal of the matrix release system in Multnomah County, Oregon, is to maintain the inmate population within limits established by the Federal court while assuring community safety.
Abstract
In the matrix process, all criminal charges and holds are ranked by seriousness and given a point score. For example, robbery has a score of 135 points, while theft has a score of 14. These scores are tabled in a computerized booking and population management system. As an inmate is booked into custody, the computer identifies the charge with the highest score and then adds points for any additional charges. To classify inmates, staff enter into the computer the type of housing required, as well as any behavior alerts. Points are added to the inmate's matrix score if he or she is assigned to a restrictive housing unit. Negative behavior categories, such as assaultive, escape risk, unstable, gang member, or psychological problems are noted to help staff responsible for supervising and transporting inmates. Inmates charged with violating facility rules are placed on pending discipline hearing status which adds 50 points to the matrix score. When the inmate population approaches capacity, staff request a computer-generated list of potential releases. The Federal court enables the sheriff to release pretrial or sentenced inmates on pass or furlough through the matrix release process. Since the matrix release system started in 1986, more than 10,000 inmates have been released because of overcrowding.
