The coroner says that the 52-year-old woman who went missing in Algonquin and was found in the Fox River on Monday is believed to have died as a result of drowning.

The Kane County Coroner’s Office said they were called around 8:50 a.m. Monday to the area of Bolz Road and Williams Road in Carpentersville.

The Carpentersville police and fire departments, East Dundee Fire Department, Kane County Sheriff’s Office, Kane County Forest Preserve Police and Algonquin Police Department were on the scene already.

The body was recovered and transported to the Kane County Coroner’s Office.

The coroner’s office said they were able to positively identify the person as Kimberly L. Koerner, 52, of Algonquin.
