Officers responded to a call of a person shot shortly after 12 a.m. and found the 26-year-old woman unresponsive on a front porch in the 9600 block of South Forest, according to Chicago Police.
She had been shot in the head and was pronounced dead at the scene, police said.
However, the victim's family identified her as Simone McKay, who they said was a student at Chicago State University and an intern with Chicago Public Schools.
The college confirmed that McKay was a biology major.
No one was in custody early Sunday as Area South detectives conducted a homicide investigation.
