A Tribune analysis of previously unreleased Illinois State Police data shows that as many as 27,000 Illinoisans over the past four years have failed to surrender or otherwise account for their guns after police stripped them of their Firearm Owners Identification cards.

And as many as 30,000 weapons are unaccounted for, the data indicates, despite laws that require people who lose their FOID cards to turn their guns in to police or transfer them to a legal owner. Commons reasons for FOID revocations include domestic violence-related infractions, mental health concerns and felony convictions.
