Overview
- Police found two custodians shot inside Mark Twain Elementary in Garfield Ridge on Monday and are treating the case as a likely murder‑suicide with a weapon recovered and Area 1 detectives leading the probe.
- About six hours later separate shootings and a stabbing left nine people shot and at least five people dead across the city including a double homicide outside a Fuller Park gas station where two victims later died at the University of Chicago Medical Center.
- A Near North Side shootout near the Magnificent Mile left two men critically wounded and a person of interest detained with a weapon recovered as investigators review surveillance, shell‑casing evidence and witness tips.
- Many of the scenes remain under active investigation with few arrests reported so far and police continuing to rely on video, shell analysis and public tips to identify suspects and reconstruct timelines.
- Local reporting from CWB Chicago added a Back of the Yards alley killing to a tally of 91 incidents in areas that lost ShotSpotter coverage and said dispatch records often show no 911 'shots fired' calls before victims were found, a pattern tied to a much higher fatality rate in that subset.
