What changed

Illinois Senate Bill 1781, introduced on February 6, 2025, proposes significant changes to law enforcement training and investigative procedures concerning homicides of individuals with a history of domestic violence. The bill mandates that State and local police officers receive specific training in investigating homicides where victims were suspected of being subject to domestic abuse. It also amends the Counties Code to require coroners to conduct preliminary investigations into deaths where domestic violence is a suspected factor, in consultation with forensic pathologists. Furthermore, a new article is added to the Code of Criminal Procedure of 1963, outlining specific investigative steps, including interviewing family members about the decedent's history of domestic violence, when certain factors are present.

This legislation will require law enforcement agencies and coroners in Illinois to update their training protocols and investigative checklists to incorporate these new requirements. Sworn law enforcement personnel investigating such deaths must be current in their domestic violence training. The bill defines specific factors investigators must consider and mandates interviews with close family or friends to establish a history of domestic violence. Compliance with these new procedures will be crucial for ensuring thorough and sensitive investigations into these specific types of homicides.

What to do next

Review and update law enforcement training curricula to include homicide investigations of domestic abuse victims.
Implement new investigative procedures for deaths with an identifiable history of domestic violence, including mandatory interviews.
Ensure all investigating sworn law enforcement personnel have current training related to domestic violence incidents.
