Security Threat Group Information

Security Threat Group Introduction

In the late 1980's the Massachusetts Department of Correction (MDOC) began to experience the emergence of street gang members being incarcerated into their system. The numbers were relatively low and the groups themselves were not organized. However, knowing the impact of gangs, the MDOC started to gather intelligence on gangs and worked closely with other agencies in identifying members.

Security Threat Group Process

This process is accomplished by a point based system in which different criteria are assigned point value.
