What I found when we looked closer
Olympia Fields is a village of 4,718 in southern Cook County, built around the Olympia Fields Country Club, which opened in 1915. It sits on US Route 30 two miles east of Interstate 57, with two Metra Electric stations providing service to the Chicago Loop.
That puts commuter, highway, and major-event traffic through a small jurisdiction, with a correspondingly small department to document it.
Following one report through the building
The first thing we do with a new department is trace where a report goes after the officer hits submit. Here, it passes through 4 hands:
- 1Patrol officer
- 2Sergeant
- 3Investigations
- 4Cook County state’s attorney
Every one of those readers needs the same facts from the first draft. That is what shaped what we built.
What we built for them
What we're watching
These are the signals that will tell us whether it's working here:
- Same-shift report completion
- Follow-up time per case
- Reports per officer per shift
Figures on this page come from the department's own published materials. We only publish Code Four results after the department reviews them.
