UPDATE: The woman found dead in the Rock River has been identified as Katrina Smith.
They tell us an off-duty firefighter spotted the body at around 1:00 p.m. today.
Right now, the Winnebago County Sheriff's Department is stepping in to Ogle County's territory, because Katrina Smith is actively missing.
Investigators want to make sure, if the unidentified woman ends up being Smith, that they are a part of the investigation from the beginning.
To be clear, investigators have not identified the body at this time.
An autopsy is scheduled for tomorrow. Ogle County detectives say they do not see any obvious signs of trauma, although they believe the woman has been in the water for a while considering she was covered in weeds and algae.
To identify the woman, investigators will start checking dental records and x-rays.
We will bring you the latest as more information becomes available.
