Illinois Statutes Chapter 725. Criminal Procedure § 5/114-13. Discovery in criminal cases

(a) Discovery procedures in criminal cases shall be in accordance with Supreme Court Rules.

(b) Any public investigative, law enforcement, or other public agency responsible for investigating any homicide offense or participating in an investigation of any homicide offense, other than defense investigators, shall provide to the authority prosecuting the offense all investigative material, including but not limited to reports, memoranda, and field notes, that have been generated by or have come into the possession of the investigating agency concerning the homicide offense being investigated. In addition, the investigating agency shall provide to the prosecuting authority any material or information, including but not limited to reports, memoranda, and field notes, within its possession or control that would tend to negate the guilt of the accused of the offense charged or reduce his or her punishment for the homicide offense. Every investigative and law enforcement agency in this State shall adopt policies to ensure compliance with these standards. Any investigative, law enforcement, or other public agency responsible for investigating any “non-homicide felony” offense or participating in an investigation of any “non-homicide felony” offense, other than defense investigators, shall provide to the authority prosecuting the offense all investigative material, including but not limited to reports and memoranda that have been generated by or have come into the possession of the investigating agency concerning the “non-homicide felony” offense being investigated. In addition, the investigating agency shall provide to the prosecuting authority any material or information, including but not limited to reports and memoranda, within its possession or control that would tend to negate the guilt of the accused of the “non-homicide felony” offense charged or reduce his or her punishment for the “non-homicide felony” offense. This obligation to furnish exculpatory evidence exists whether the information was recorded or documented in any form. Every investigative and law enforcement agency in this State shall adopt policies to ensure compliance with these standards.
