Oscar D. Isaya-Corrales died after an off-duty FBI agent shot him in Pilsen, the FBI and the medical examiner said.

Isaya-Corrales died uncharged. The medical examiner's homicide ruling classifies the death. It does not charge the agent, and the FBI's Inspection Division review is not a state's attorney's decision. Ald. Byron Sigcho-Lopez wants the Illinois attorney general and the Cook County state's attorney to investigate the shooting outside that review.

The FBI said an off-duty agent shot and killed a man Monday evening, Oct. 26, 2026, in Chicago's Pilsen neighborhood. The Chicago Sun-Times reported the agent was driving home from work in an FBI vehicle around 5:30 p.m. when he saw the man "discharging a firearm into a group of innocent people" near 18th Street and Union Avenue, that at least two shots were fired before the agent intervened "to stop the ongoing threat," and that a Chicago police report puts the agent at 41. NBC Chicago reported the shooting was around 5:30 p.m. near West 18th Street and Union Avenue, that the agent was driving home alone in a bureau-issued vehicle, and that the agent "engaged with the individual" to stop him. FOX 32 Chicago reported the location as West 18th Street and South Union Avenue. CBS Chicago reported the 1700 block of South Union Avenue, under the Dan Ryan Expressway. The Cook County medical examiner's office identified him as 27-year-old Oscar D. Isaya-Corrales, NBC Chicago, CBS Chicago, and FOX 32 Chicago reported. The Sun-Times spelled the name Oscar Isaya-Corrales, without the middle initial. ABC7 Chicago used Oscar Corrales.

ABC7 Chicago reported sources said the agent got out of his vehicle and shot Corrales, and that the FBI confirmed the agent engaged with him "to stop the ongoing threat." ABC7 Chicago reported a senior official told ABC News that the group was a homeless encampment. The FBI wording printed by the Sun-Times and by NBC Chicago is "a group of innocent people," and those stories do not use the words homeless encampment. FOX 32 Chicago reported the FBI said he was firing a gun into a homeless encampment. The Sun-Times reported he suffered gunshot wounds to both legs, his chest, and his right flank, that he was pronounced dead at Stroger Hospital less than an hour after he was shot, and that the medical examiner ruled the death a homicide. CBS Chicago reported an autopsy found he died of multiple gunshot wounds and that the death was ruled a homicide. That ruling is the medical examiner's manner of death. It is not a criminal charge against the agent, and Isaya-Corrales was not charged either. The Sun-Times reported a handgun was found under a bicycle. ABC7 Chicago reported video showed what appeared to be a gun beneath an e-bike. CBS Chicago reported video of the agent with his gun drawn at the man, who was on the ground near an e-bike. A bicycle and an e-bike are not the same description. NBC Chicago reported the agent was not injured and that no additional injuries were reported. FOX 32 Chicago reported no other injuries. The FBI said its Inspection Division is reviewing the shooting, the Sun-Times, NBC Chicago, CBS Chicago, and FOX 32 Chicago reported.

The FBI described him as a Venezuelan national without legal status who was taken into custody at the border in 2023 and later released, the Sun-Times, ABC7 Chicago, NBC Chicago, and FOX 32 Chicago reported. NBC Chicago published a Department of Homeland Security statement that said he entered through the southern border in October 2023, was arrested by Customs and Border Protection, and was released, and that said ICE was not involved on Oct. 26. The Sun-Times reported an arrest report filed May 25 said he was allegedly caught shoplifting five necklaces valued at nearly $320 at a Nordstrom store at 55 E. Grand Ave., that he had a Guatemalan passport "that did not belong to him," and that officers could not immediately determine whether the passport was stolen. The Sun-Times reported a warrant was issued June 1 when he failed to appear in court. ABC7 Chicago reported the May retail-theft arrest, the passport allegation, and a June warrant after he failed to appear. FOX 32 Chicago, citing FOX News, reported he had previously been arrested in California and released despite an ICE detainer. That California arrest is not in the FBI statement the other outlets printed. Arrest reports and a warrant are not a finding in the shooting.

Ald. Byron Sigcho-Lopez, of the 25th Ward, called for an independent investigation by the Illinois attorney general and the Cook County state's attorney, FOX 32 Chicago, CBS Chicago, and ABC7 Chicago reported. CBS Chicago and ABC7 Chicago reported he said the FBI and its Inspection Division cannot, "under any circumstances, conduct a thorough, credible investigation of itself," and both used the words "a young man." FOX 32 Chicago printed the same demand and the same sentence about the Inspection Division, and printed "a man" rather than "a young man." ABC7 Chicago reported the name in his statement as Oscar Isaya Corrales, without the hyphen the medical examiner's identification uses. FOX 32 Chicago and CBS Chicago reported he also asked Chicago police to preserve evidence, including body-camera footage and witness statements. The agent has not been charged. The review and the alderman's request are not charges.
