Law enforcement must collect and submit biometric data to national databases like NamUs if a person remains missing for 60 days. Illinois will soon have new statewide rules for how police handle missing persons cases, requiring immediate reports and expanded use of federal databases. What we know:The Missing Persons Identification Act (SB 24), signed into law Aug. 15 by Gov.
