Division of Internal Investigation
The Illinois State Police Division of Internal Investigation (DII) conducts investigations regarding allegations of administrative and criminal misconduct by State Police employees (civilian and sworn). In addition, DII investigates allegations of criminal misconduct by any state employee committed during the course of their employment at the request of the Governor. Among its diverse responsibilities, the DII investigates use of deadly force incidents by ISP Employees, financial crimes, theft of state property, and charges of abuse or neglect of inmates incarcerated at state correctional institutions and residents of mental health facilities, as well as other criminal allegations.
Background Investigations Unit
The Division is responsible for performing employee background investigations on individuals being considered for code and sworn positions within the Illinois State Police, non-Illinois state law enforcement agencies, other Illinois criminal justice agencies, and non-governmental employees who have regular access to ISP facilities or sensitive data.
Identified Offender Program
The Division manages the statewide Identified Offender Program. The program is designed to improve the safety within the approximately 1,170 licensed nursing care facilities regulated by the Illinois Department of Public Health (IDPH). There is currently at least one long-term care facility in each of state’s 102 counties. The Identified Offender Program (IOP) was developed due to a provision of the Nursing Home Care Act. The program was designed to improve safety within skilled nursing centers by identifying individuals with a criminal conviction history and conducting a behavioral risk assessment to determine the potential risk those identified individuals pose to other patients, staff and visitors. In April of 2010, it was determined by the Governor’s Office, investigative responsibility for the IOP program would transfer from an IDPH vendor to the Illinois State Police (ISP). On June 1, 2010, the Division of Internal Investigation (DII) developed procedures and implemented an initiative to comply with the strict statutorily mandated timelines for the Identified Offender Program utilizing contractual investigators. Investigators complete a Criminal History Analysis (CHA) investigation on individuals with a criminal conviction history. The investigation provides an assessment of a resident’s potential to commit violence against other patients, staff, and visitors. The investigative case file is forwarded to a forensic psychologist who completes a behavioral risk assessment of the identifies offender. The risk assessment is distributed to the IDPH, the facility in which the offender is residing, the local police department where the facility is located, and the State Ombudsman.
