CHICAGO, ILLINOIS — The Chicago community is grappling with the tragic loss of Gabriella Arellano, 17, who was found shot to death Sunday morning in an alley on the city’s East Side. The fatal incident occurred in the 11000 block of South Mackinaw Avenue, leaving family, friends, and neighbors in shock and mourning.
Police report that Gabriella, affectionately known as Gabby, was discovered around 10:18 a.m. on October 26, 2025, suffering from two gunshot wounds to the head. Emergency responders were called to the scene after a 911 report described an unconscious female lying in the alley.
Officers from the Chicago Police Department’s 4th District arrived promptly and found Gabriella unresponsive. Despite immediate attention from first responders, she was pronounced deceased at the scene. The suddenness of the tragedy has left the East Side community deeply unsettled.
Preliminary investigations indicate that Gabriella was seen walking with two unidentified males shortly before the gunfire occurred. Detectives are reviewing surveillance footage in hopes of identifying these individuals and determining the sequence of events that led to her death.
Authorities have noted that no 911 calls reporting gunshots were received at the time of the incident. This absence of immediate alerts has raised concerns about monitoring and public safety in the neighborhood.
The area had previously been covered by ShotSpotter gunfire detection technology, which could have provided real-time alerts. However, the city’s contract with the program was recently discontinued, leaving residents without this layer of security. Officials are examining how the lack of monitoring may have affected response times.
At present, no suspects are in custody. The Area Two Bureau of Detectives is leading the homicide investigation, working tirelessly to gather evidence, interview witnesses, and piece together the events that led to Gabriella’s death.
Family members, friends, and neighbors are left reeling from the loss. Gabriella is remembered as a vibrant, bright teenager whose life was full of promise. The community has begun organizing vigils and memorials to honor her memory and support those grieving her untimely passing.
Authorities are urging anyone with information regarding the incident to come forward. Tips can be submitted anonymously, and investigators emphasize that even small details could help identify the individuals involved and bring justice for Gabriella.
As Chicago mourns Gabriella Arellano, the community is reflecting on the importance of safety, vigilance, and support for young people in the city. Her family and friends hope that her death will serve as a reminder of the need for stronger protections and swift action to prevent future tragedies.
