Bill
SB 1587
Requires ISP to quarterly report homicide and firearm-attack data to ICJIA, which will publish standardized, agency-by-agency statistics for public access.
Status snapshot
- Bill number: SB 1587
- Subject: Criminal justice reform — homicide reporting and victims’ case-review provisions (file contains multiple state versions; this summary focuses on the Illinois version sponsored by Sen. Robert Peters and co-sponsors).
- Key sponsors (IL): Robert Peters (primary), Mattie Hunter (chief co-sponsor) and several other Illinois senators.
- Companion bills: HB 748, HB 1974.
- Major procedural steps: introduced Feb 4, 2025 (IL), multiple floor and committee amendments filed (including Senate Amendments 001 & 002), active through spring 2025.
Purpose and intent
- To increase statewide transparency and consistency in homicide and firearm-related aggravated-assault reporting by requiring the Illinois State Police (ISP) to submit specified homicide-related data to the Illinois Criminal Justice Information Authority (ICJIA). The ICJIA must compile, study, and publish the data publicly on a recurring basis.
Key provisions (Illinois text)
- New Section 16 added to the Illinois Criminal Justice Information Act (20 ILCS 3930/16 — “Homicide reporting”):
- Requires ISP, beginning (original text) Jan 1, 2026 — (amendment) July 1, 2026 — to submit, on a quarterly basis, specified homicide-related information to ICJIA (or provide via a web portal).
- ICJIA must study/compile the submissions and publish the data on its public website in a format it determines (quarterly publication).
- Required published data items for each reporting agency include:
1. Number of homicides;
2. Number of aggravated assaults with a firearm;
3. Number of those aggravated assaults and homicides cleared by arrest;
4. Number of those aggravated assaults and homicides cleared/closed for reasons other than arrest;
5. For cases closed for reasons other than arrest, counts broken out by reason (e.g., alleged perpetrator deceased; prosecution declined; suspect in custody in another jurisdiction; other exceptional means outside law enforcement control);
6. Number of the cases from (1) and (2) referred to the relevant State’s Attorney’s office for prosecution.
- Amends the Uniform Crime Reporting Act (50 ILCS 709/5‑10) to require ISP to provide the above information to ICJIA in a prescribed form.
Who is affected
- Illinois State Police (data collection/submission duties).
- Illinois Criminal Justice Information Authority (compilation, study, publication).
- All local law enforcement agencies that submit homicide/aggravated-assault data to ISP.
- Prosecutors and State’s Attorney offices (tracking referrals).
- Families, researchers, policymakers and the public (access to agency-by-agency homicide clearance and firearm-assault statistics).
Procedural/timeline notes
- Original effective/start date in introduced text: January 1, 2026. Amendment(s) shift the ISP submission start to July 1, 2026, with ICJIA publishing by September 1, 2026, and thereafter on a recurring (quarterly) schedule. Final timing depends on which amendment is adopted.
- Multiple floor and committee amendments have been filed; as of the latest actions the bill has undergone committee consideration and amendment.
Potential impacts and considerations
- Increases public transparency around homicide clearance and firearm-assault outcomes, enabling comparisons across agencies.
- May inform policy debates, resource allocation, and oversight of homicide investigations.
- Implementation will require ISP and ICJIA capacity for standardized, regular data submission, compilation, and public reporting.
- Data publication raises standard considerations around victim privacy and confidentiality of ongoing investigations; the bill allows ISP/Authority to prescribe formats and may limit disclosure of sensitive information per existing laws.
Note on other texts in the file
- The bill file includes unrelated versions/texts from other states (e.g., an Arizona provision on health regulatory boards contracting with private vendors and a Hawaii retainage statute). Those are separate measures and not part of the Illinois criminal-justice reporting proposal summarized above.
