FULL STATEMENT FROM COPA
On March 29, 2021 the Civilian Office of Police Accountability (COPA) received notification from the Chicago Police Department of an officer-involved shooting near 2400 S. Sawyer. COPA investigators arrived at the scene and immediately commenced an investigation.
While COPA is in the very early stages of this investigation, it has been determined that officers were responding to the area as a result of shots fired and encountered two suspects.

The other individual who fled was shot and killed by the pursuing officer. The involved officer discharged his weapon once and the incident has been captured on body worn camera. The deceased individual has been identified as, Adam Toledo, who is reportedly 13 years of age.
Due to the age of the victim, absent the issuance of a court order and pursuant to the Juvenile Court Act (705 ILCS 405/5-905(5)), COPA is prevented from publicly releasing videos involving a juvenile. Materials that can be released including 911 calls, OEMC transmissions, Tactical Response and Incident Reports will be released within 60 days of the incident and in accordance with the City's Video Release Policy.
COPA's is committed to a full and thorough investigation into the officer's use of deadly force to determine if their actions were in accordance with Department policy and training and asks for the public's patience.

FULL STATEMENT FROM CHICAGO POLICE SUPT. DAVID BROWN
My greatest fear as the Superintendent of the Chicago Police Department has been a deadly encounter between one of our own and a juvenile especially given the recent rise in violent crimes involving juveniles throughout our city. Unfortunately, this fear became a reality earlier this week. Any loss of life is tragic, especially when it involves youth. On behalf of the entire Chicago Police Department, I extend my condolences to the family of the juvenile, who was fatally shot by a Chicago Police officer in the early morning hours of Monday, March 29, 2021. I'm not naming this young man because I do not want to violate his privacy as a juvenile.
The split-second decision to use deadly force is extremely difficult for any officer, and is always a heavy burden to bear for officers involved in fatal shooting incidents. We fully support the investigation being conducted by the Civilian Office of Police Accountability (COPA), and adamantly call for the release of any and all video, including body-worn camera footage, related to the incident, as permitted by laws pertaining to juveniles.
The specifics of the incident, including the comprehensive use of force investigation, are being investigated by COPA with full cooperation of the Chicago Police Department. The officer involved has been placed on routine administrative duty for a period of 30 days. This matter is under investigation, and all further inquiries can be directed to COPA at (312) 746-3609.
FULL STATEMENT FROM MAYOR LORI LIGHTFOOT
"As a mother of a thirteen-year-old myself, I can only imagine the incredible pain this boy's parents are experiencing at this moment. My heart goes out to them. The facts and the circumstances around this case are under investigation, but we must ask ourselves how our social safety net failed this boy leading to the tragic events in the early hours of Monday morning.
While the investigation is ongoing, it is critically important that COPA releases relevant videos first to the family, and then to the public, as quickly as possible with appropriate protections given his age. Because his family and the public will undoubtedly have many questions, we must release any relevant videos as soon as possible. Recognizing that these are the most complex cases that COPA investigates, transparency and speed are crucial."
FULL STATEMENT FROM TOLEDO FAMILY
"Adam Toledo was killed early Monday morning, due to the unreasonable conduct of a Chicago Police Officer. We are confident that the Chicago Police Department and the Civilian Office of Police Accountability will conduct a thorough investigation, that there will be transparency, and that Toledo Family will find out the truth of what happened to Adam. Adam was killed on March 29th, 2021, but the Toledo Family was only notified of his death two days later. Adam was a seventh grade student at Garvey School, enjoyed sports and was a good kid. He did not deserve to die the way he did. The Toledo Family will seek justice for this reprehensible crime and requests privacy during this time of mourning. The Toledo Family is represented by Weiss Ortiz PC."
