The GIU is a specialized unit within the Corrections Bureau of the Kane County Sheriff's Office. Each member of the GIU is a volunteer and has accepted this duty as a collateral assignment. The unit is made up of a Lieutenant, who manages its overall operation and direction, a Sergeant as first line supervisor, and nine Corrections Officers. The Corrections Officers come from every shift and duty assignment within the facility. The unit's function is to identify street gang members that are confined in the Kane County Adult Justice Center. The identification of street gang members supports the detainee housing classification system. The proper classification and housing of detainees will prevent incidents and acts of violence among gang members, thereby enhancing the safety and security for everyone. The unit members collect this information by analyzing tattoos, conducting interviews and observing the interaction of detainees with one another. The Officers also analyzes the graffiti that is found during routine cell searches. The unit is also utilized as a valuable intelligence resource by other specialized gang enforcement units within Kane County, the Illinois State Police, the Illinois Department of Corrections and Federal Law Enforcement Agencies. The unit members attend numerous monthly meetings held by local law enforcement agencies regarding gang crime and activities within Kane County. This information allows unit members to assess any potential retaliatory threat due to assault or shooting on the street.
