The Madison County Coroner's Office is investigating the death of a Pontoon Beach woman whose body was found in a lake.
The coroner's office has identified the woman as 53-year-old Pamela Butkovich, of 328 Osprey Drive in Pontoon Beach. Her body was discovered Friday morning floating in Mallard Lake, located off Illinois 162.
Pontoon Police had also received a missing persons report filed by the woman's husband, 64-year-old Gary Butkovich. The man told police that he found a note that his wife left in their home that indicated she might do harm to herself.
Investigators have not determined if the woman's death was a suicide. An autopsy has been scheduled for Saturday.
Funeral arrangements are pending at Irwin Chapel Funeral Home in Granite City.
