South Suburban Major Crimes Task Force (SSMCTF)

The mission of the South Suburban Major Crimes Task Force is to provide comprehensive investigative services to all participating member agencies. These services include, but are not limited to: major drug related violent crimes including homicides, non-parental kidnappings, and other exceptionally heinous crimes when requested to do so by the Police Chief of the member agency with the approval of the Board of Directors. 

The SSMCTF, under the Command of the Cook County Sheriff's Police Department and the Illinois State Police, has the responsibility of supervising 54 south suburban Police Departments who have assigned approximately 150 investigators. These members investigate real or suspected violent crimes which necessitate a substantial commitment of resources for a prolonged period of time, or which require the application of complex or unusual investigative techniques and expertise.
