Surveillance video recorded near the crime scene shows Parker struggling with two men or three men as they reportedly tried to take her purse at the corner of Melrose and North Kenmore avenues just before 3 a.m., October 2. She was shot when she tried to flee the scene after the altercation.
After the shooting, Parker was taken to a nearby hospital, where she died in surgery.
The teenager's identity has not been released because he is a minor. Police are seeking two other suspects in connection to the case.
