IL HB3632

Allows immediate family members to request case file reviews for "open unresolved murders" (cases older than 3 years with exhausted leads and no identified perpetrator), with agencies required to complete reviews within 6 months and conduct full reinvestigations if probative leads are identified

Requires law enforcement agencies to employ family liaison officers at a ratio of 1 officer per 40 homicides (based on 5-year average), who serve as dedicated points of contact between victims' families and investigators with mandatory contact at least monthly for the first 6 months

Establishes a 5-year waiting period before additional case reviews can be requested if no reinvestigation is warranted or if a reinvestigation fails to identify a suspect, unless materially significant new evidence emerges

Mandates the Illinois Criminal Justice Information Authority to publish annual statistics on open unresolved murders beginning 3 years after enactment, including data broken down by murder degree, weapon type, location, and demographics of solved versus unsolved cases

Applies to all murders occurring on or after January 1, 1970, and requires agencies to adopt compliance rules within one year, including disciplinary sanctions for employees who willfully fail to comply
