In contrast to the traditional consultant's role, which is often limited to assessment of psychopathology or dangerousness, this article argues for a more active and investigatory case management partnership with law enforcement and security personnel. The threat assessment and case management process can be divided into data collection, data analysis and case management implementation. Mental health professionals' contribution to data collection could include reviewing existing documents, using research to increase information's impact, fully exploiting human sources and conducting contact and worksite interviews. A case management interdisciplinary team can estimate the level and type of threat present, identify potential "triggers," design information and monitoring strategies, design contingency plans and interventions and plan and implement termination.
