CHICAGO, IL – A disturbing video has surfaced showing the aftermath of a fatal shooting on the CTA Red Line platform at 69th Street Station, where a woman was found dead after being shot in the neck.

Authorities have identified the victim as Kamira McMillen, believed to be between 25 and 35 years old.

The shooting occurred around 9:46 p.m. Tuesday when McMillen became engaged in an argument with another woman on the platform, according to police.

During the dispute, the suspect pulled out a firearm and shot McMillen once in the neck before fleeing the scene.

A single bullet shell casing can be seen in the video footage taken at the scene.

Emergency responders transported McMillen to the University of Chicago Medical Center in critical condition, but despite medical intervention, she was later pronounced deceased.

Chicago Police Department’s Area One detectives have launched an investigation into the fatal shooting and are actively searching for the female suspect involved.

At this time, no arrests have been made, and authorities have not released a description of the shooter.

The motive behind the argument remains unclear, and it is unknown whether McMillen and the suspect had any prior relationship.

Investigators are working to determine whether surveillance cameras captured the incident or if there were any witnesses on the platform during the shooting.

Anyone with information is urged to contact Chicago police or provide an anonymous tip through CrimeStoppers.
