Sumner, IL crime: up or down?
Newest FBI monthly report: Sep 2026
Past years either weren't sent in full or are too few, so there's no fair usual to compare with.
Missing or partial reports to the FBI: Jan 2024 – Feb 2026. Those months are left out of every comparison.

Is Sumner safe?
Crime Radar doesn't grade towns as safe or unsafe: one number can't say what a street is like, and the FBI warns against ranking places. What these reports can say is whether Sumner has more or fewer reported crimes than it usually does. For one block, open it on the map.
How this works
Sumner Police Department sends monthly counts of violent and property crime to the FBI. Crime Radar compares the newest complete three months with the same months in past years, and only calls a change when it's bigger than this department's usual ups and downs. Months with missing reports are left out, so a reporting gap never looks like a safe stretch. These are totals for everywhere the department patrols, not one street.
Not every crime reaches these numbers: in the national victim survey, about 6 in 10 serious violent crimes and 3 in 10 property crimes were reported to police in 2024 (BJS).
