A woman's body was reportedly pulled from the North Branch of the Chicago River Saturday morning on the Northwest Side, officials said.
Chicago Fire Department crews responded to a 911 call at 10:10 a.m. from a passerby who observed the body in the river in the 2600 block of West Irving Park Road.
Officials have not confirmed if the body is a man or woman, but say the remains appear to be female.
The Medical Examiner's Office will conduct an autopsy to determine if the death is criminal or suicide, officials said.
The 'death investigation' will reportedly continue until the Medical Examiner determines how the death occured.
