Illinois Statutes Chapter 50. Local Government § 727/1-10. Investigation of officer-involved deaths; requirements

(a) Each law enforcement agency shall have a written policy regarding the investigation of officer-involved deaths that involve a law enforcement officer employed by that law enforcement agency.

(b) Each officer-involved death investigation shall be conducted by at least 2 investigators, or an entity or agency comprised of at least 2 investigators, one of whom is the lead investigator. The lead investigator shall be a person certified by the Illinois Law Enforcement Training Standards Board as a Lead Homicide Investigator, or similar training approved by the Illinois Law Enforcement Training Standards Board or the Illinois State Police, or similar training provided at an Illinois Law Enforcement Training Standards Board certified school. No investigator involved in the investigation may be employed by the law enforcement agency that employs the officer involved in the officer-involved death, unless the investigator is employed by the Illinois State Police and is not assigned to the same division or unit as the officer involved in the death.

(c) In addition to the requirements of subsection (b) of this Section, if the officer-involved death being investigated involves a motor vehicle crash, at least one investigator shall be certified by the Illinois Law Enforcement Training Standards Board as a Crash Reconstruction Specialist, or similar training approved by the Illinois Law Enforcement Training Standards Board or the Illinois State Police, or similar training provided at an Illinois Law Enforcement Training Standards Board certified school. Notwithstanding the requirements of subsection (b) of this Section, the policy for a law enforcement agency, when the officer-involved death being investigated involves a motor vehicle collision, may allow the use of an investigator who is employed by that law enforcement agency and who is certified by the Illinois Law Enforcement Training Standards Board as a Crash Reconstruction Specialist, or similar training approved by the Illinois Law Enforcement Training Standards Board, or similar certified training approved by the Illinois State Police, or similar training provided at an Illinois Law Enforcement Training Standards Board certified school.

(d) The investigators conducting the investigation shall, in an expeditious manner, provide a complete report to the State's Attorney of the county in which the officer-involved death occurred.

(e) If the State's Attorney, or a designated special prosecutor, determines there is no basis to prosecute the law enforcement officer involved in the officer-involved death, or if the law enforcement officer is not otherwise charged or indicted, the investigators shall publicly release a report.
