An off-duty FBI agent's fatal shooting in Pilsen: Ald. Sigcho-López wants state and county prosecutors to investigate. What the City can and can't do

An off-duty FBI agent shot and killed a 27-year-old man near 18th Street and Union Avenue in Pilsen around 5:30 p.m. Monday, Oct. 26. The FBI says the agent, driving home in a bureau vehicle, saw the man firing at least two shots into a group of people and intervened "to stop the ongoing threat," the Chicago Sun-Times reported. No one else was hurt. Police found a handgun under a bicycle, according to a police report cited by the Sun-Times. The medical examiner ruled the death a homicide.

Why it matters: the shooting is being reviewed by the FBI's own Inspection Division. Ald. Byron Sigcho-López (25th), whose ward includes the site, has asked Illinois Attorney General Kwame Raoul and Cook County State's Attorney Eileen O'Neill Burke to open an independent investigation, Block Club Chicago reported. Residents asking who is accountable for a federal agent's use of force on a City street will find that the City's own tools are limited.

What's been reported

According to a police report cited by the Sun-Times, officers responding to a call of an officer in distress found the agent still aiming at the man after he had been wounded and was on the ground. The FBI said in a statement that it "takes all shooting incidents involving our agents or task force members seriously."

Sigcho-López questioned why the agent kept aiming at the man after he was down and whether the agent was acting alone or as part of a task force, Fox 32 reported. He asked the Chicago Police Department to preserve all evidence, including body camera footage and witness statements, and said the FBI cannot credibly investigate itself. He also said the City should review how it works with federal agencies, beginning with CPD's task force agreements, and that the issue is "no longer only about ICE," Block Club reported.

The FBI's account has not been independently confirmed, and no findings have been released.

What our records add

COPA's reach. The Civilian Office of Police Accountability investigates members of the Chicago Police Department. A COPA FAQ, written for the 2024 Democratic National Convention, says it has jurisdiction "solely" over CPD members and forwards complaints about other agencies' officers to their oversight bodies. In March, the Council voted 50 to 0 for Ald. Jessie Fuentes' ordinance, O2025-0020004, expanding what COPA can investigate about CPD officers, including whether they helped federal immigration enforcement, WTTW reported. That change covers Chicago officers' conduct, not federal agents'.

What the Council has done about federal agents. The Council's tools have been resolutions. In October 2025 it adopted, 47 to 0, a resolution from Ald. Andre Vasquez (40th) calling on Illinois' members of Congress to investigate every instance of potential misconduct by Homeland Security and other deputized agents in Chicago, and a resolution from Sigcho-López condemning federal immigration agents' practices that endanger children. Resolutions state the Council's position; they don't compel an investigation.

Task force agreements. We found no CPD agreement with the FBI among the items the Council has voted on this term in our records. We will update this story if one comes before the Council.

What's next

• The FBI Inspection Division's review is ongoing, with no timeline announced.
• Neither the Attorney General's office nor the State's Attorney had said publicly whether they would investigate, in the coverage we reviewed.
• The Council's budget hearings for COPA (Nov. 5) and the Community Commission for Public Safety and Accountability (Nov. 10) are the next scheduled times members can ask oversight agencies about it on the record, under the hearing schedule.
