Officer Krystal Rivera, 36, a four-year Chicago Police Department veteran and mother, was killed on June 5, 2025, after being struck by a single round fired by her partner during a late-night foot pursuit in the Chatham neighborhood. The chase began just before 10 p.m. in the 8200 block of South Drexel Avenue after officers moved on a person believed to be armed; inside a small apartment described as filled with guns and drugs, another man raised a rifle toward officers.

The autopsy found the bullet entered near Rivera’s left armpit, just outside vest coverage, and pierced her lung; the Cook County Medical Examiner ruled the death a homicide. Colleagues rushed her toward a hospital but a squad car malfunctioned, crashed and caught fire, forcing a transfer to a second vehicle; she was pronounced dead less than an hour later. Investigators recovered multiple firearms, including AR-style rifles, a Glock and a 60-round drum magazine, plus heroin, cocaine and marijuana.

The Civilian Office of Police Accountability opened an investigation and a judge blocked release of body camera and related records while criminal and disciplinary matters proceed.

Did anyone in Chatham see officers or activity near the 8200 block of South Drexel Avenue that night, or does anyone have information about the hallway chase?
